TECHNICAL FIELD
[1] The present disclosure relates to magnetic impellers, and more particularly to magnetic impellers adapted for mixing a fluid. BACKGROUND TECHNIQUE
[2] Traditionally, magnetic fluid impellers used a magnetic stir bar containing a hermetically sealed bar magnet. Such magnetic impellers often do not provide desirable mixing efficiency, particularly in large scale operations. Additionally, traditional magnetic stir bars have a tendency to “walk” or disengage with the magnetic drive magnet, which can disturb mixing and decrease efficiency. Other magnetic impellers have been developed to increase mixing efficiency, such as superconductor driven stir sets, but such sets typically require the use of a specialized vessel or physical engagement or retention with the vessel.
[3] Therefore, there is a need to develop a magnetic impeller that overcomes the above mentioned disadvantages, namely a magnetic impeller with improved mixing efficiency over a traditional magnetic stir bar that can be used in a wide range of designs. container and does not require physical attachment or connection to a container.

[64] Expert technicians recognize that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help improve understanding of embodiments of the invention. DETAILED DESCRIPTION OF THE PREFERRED MODALITY(S)
[65] The following description in combination with the figures is provided to aid in understanding the teachings revealed here. The following discussion will focus on specific implementations and modalities of the teachings. This focus is provided to help describe the teachings and should not be interpreted as limiting the scope or applicability of the teachings. However, other modalities may be used based on the teachings as revealed in this application.
[66] The terms “comprises”, “comprising”, “includes”, “including”, “has”, “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a method, article or apparatus comprising a list of features is not necessarily limited to just those features, but may include other features not expressly listed or inherent in such method, item or apparatus. Also, unless expressly stated to the contrary, “or” refers to an inclusive-or and not an exclusive-or. For example, a condition A or B is met by any of the following: A is true (or present) and B is false (or not present), A is false (or not present), and B is true (or present), and both A and B are true (or present).
[67] Also, the use of “a” or “an” is employed to describe elements and components described here. This is done purely for convenience and to provide a general sense of the scope of the invention. That description should be read to include one, at least one, or the singular as well as including the plural, or vice versa, unless it is clear that it is otherwise intended. For example, when a single item is described here, more than one item can be used in place of a single item. Similarly, where more than one item is described here, a single item may be substituted for more than one item.
[68] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by a person of ordinary skill in the art to which this invention belongs. The materials, methods and examples are illustrative only and are not intended to be limiting. To the extent not described here, many details regarding specific materials and processing acts are conventional and can be found in books and other sources understood in the fluid mixing art.
[69] Unless otherwise specified, the use of any numbers or ranges when describing a component is approximate and illustrative only and should not be limited to include only that specific value. Reference to values mentioned in ranges is intended to include each and every value included in that range.
[70] The following description is directed to embodiments of a magnetic impeller adapted to mix a fluid.
[71] In a specific aspect, a magnetic impeller according to one or more embodiments described here may be capable of aerodynamic levitation. As used herein, "aerodynamic levitation" refers to the translation of a blade along a pressure gradient towards a relatively lower pressure formed by the blade in the fluid. Magnetic impellers, such as that disclosed in US Patent 7,762,716 and US Patent 6,758,593, are not capable of aerodynamic levitation. For example, although these patents describe “levitation”, such “levitation” is caused by fragmented turbulence generated below the magnetic impeller or by a superconducting element. This type of “levitation” is not aerodynamic levitation as defined here, since aerodynamic levitation can be achieved only by generating a relatively lower pressure in the fluid which effectively pulls the impeller towards the lower pressure, thereby causing translation of at least least a portion of the impeller. Certain embodiments of the magnetic impeller described here can aerodynamically levitate and generate efficient mixing action at very low speeds without the build-up of frictional heat.
[72] In a specific embodiment, the magnetic impeller may be a decoupled magnetic impeller capable of aerodynamic levitation. In this way, the blade can be decoupled from a rotating element and adapted to translate in a direction perpendicular to the rotating element.
[73] In another aspect, a magnetic impeller according to one or more embodiments described here may be non-superconducting. As used herein, "non-superconducting" refers to a magnetic impeller that does not incorporate or otherwise use a superconducting element to induce levitation or rotation. Indeed, a specific advantage according to one or more of the embodiments described here is that the magnetic impeller can levitate, in particular, levitate aerodynamically, at low speeds without the need or use of superconducting elements, which are extremely expensive and require ultracold temperatures. (eg -183°C) to induce a superconducting field.
[74] In a further aspect, a magnetic impeller according to one or more embodiments described herein may include a collapsible blade element. In a specific embodiment, the magnetic impeller may have a first configuration and a second configuration, where the magnetic impeller is adapted to have a narrower profile in the first configuration than in the second configuration. A specific advantage according to one or more of the embodiments described herein is that the magnetic impeller may be positioned in a vessel having an opening that defines a diameter that is smaller than the diameter of the collapsible paddle element in the operating configuration.
[75] In yet another aspect, a magnetic impeller according to one or more embodiments described herein may include a blade adapted to change shape, orientation, size or characteristic after being rotatably engaged. In a specific embodiment, a main surface of the blade may increase in width during rotation. In another embodiment, the blade may include at least one opening extending through the blade adjacent a leading or trailing edge thereof. In an additional embodiment, the paddle may be flexible. A specific advantage according to one or more embodiments described herein is that a paddle adapted to change after being rotatably engaged can be adapted to provide varying mixing characteristics upon varying rotational speeds.
[76] In yet a further aspect, a magnetic impeller according to one or more embodiments described herein may include a magnetic impeller having a cage at least partially bounding a blade. According to one or more embodiments, a cage can improve the stability of the magnetic impeller and prevent disengagement of the magnetic coupling between the magnetic impeller and a magnetic drive. Furthermore, embodiments of the present disclosure may allow consistent mixing action with a low variability of paddle velocity during mixing.
[77] In yet another aspect, a magnetic impeller according to one or more embodiments described herein may include a magnetic impeller disposed, or adapted to be disposed in a flexible or partially flexible vessel. In a specific embodiment, the flexible vessel may include a flexible surface and a rigid surface. In a further embodiment, the rigid surface may be disposed on a lower wall of the vessel. In a specific embodiment, the rigid surface may be substantially flat. The magnetic impeller can be physically decoupled from the flexible vessel. In this way, the magnetic impeller can swivel along a surface of the flexible vessel.
[78] Referring now to the figures, Figures 1 to 9B include a magnetic impeller 100 in accordance with one or more embodiments described herein. Magnetic impeller 100 may generally include a rotating element 102 rotatably coupled to an impeller bearing 104 along an axis of rotation AR. the rotatable element 102 may have a first surface 108 and a second surface 110 disposed opposite the first surface 108. The rotatable element 102 can be rotatably induced to impart a mixing action on a fluid surrounding the magnetic impeller 100.
[79] In a specific embodiment, the rotatable element 102 may include a center 112 and a plurality of blades 114 extending radially from the center 112. The blades 114 may extend perpendicular to the center 112 or at an angle relative thereto, for example , an angle other than 90 degrees with respect to an outer surface of center 112. Blades 114 of rotating element 102 may extend off center 112 by a length, LB, as measured by a longer length of blade 114. , LB, is the same among all blades 114. In a specific embodiment, blades 114 may be substantially straight when viewed from a top view so as to form a substantially straight main surface 116. In another embodiment, blades 114 may be have an arched or otherwise polygonal configuration when viewed from a top view.
[80] In a specific embodiment, the magnetic impeller 100 may include at least 2 blades, such as at least 3 blades, at least 4 blades, at least 5 blades, at least 6 blades, at least 7 blades, at least 8 blades, at least 9 paddles or even at least 10 paddles. In an additional embodiment, the magnetic impeller 100 may include not more than 20 blades, such as not more than 15 blades, not more than 10 blades, not more than 9 blades, not more than 8 blades, not more than 7 blades, not more than 6 blades, not more than 5 blades, or even not more than 4 blades. In a more preferred embodiment, the magnetic impeller 100 may include 4, 5 or even 6 blades 114. The blades 114 may be dispersed around the hub 112 in equal increments, for example, so that the magnetic impeller 100 may be rotationally symmetrical. .
[81] In a specific embodiment, at least one of the blades 114 may have a density that is less than a density of the fluid in which the magnetic impeller 100 is to be disposed. In this way, the blades 114 can be more buoyant than the fluid. In an alternative embodiment, the paddles 114 may have a density that is greater than the density of the fluid being mixed. In yet another embodiment, the blades 114 may have a density substantially similar to the density of the fluid being mixed.
[82] The main surface 116 of each blade 114 may have a width, WB, as defined by the distance between a leading edge 118 of blade 114 and a trailing edge 120 of blade 114, when viewed from a top view. in a specific embodiment, an LB/WB ratio can be at least 1, such as at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, or even at least 10. A blade surface area, SAB, may be defined by the surface area of the main surface 116 of blade 114 as measured by LB and WB.
[83] As shown in Figures 3 and 4, the rotating element 102 may have an internal hole 122 defining an interior surface 124 oriented parallel to the axis of rotation AR. hole 122 may extend through the height of rotary element 102. Hole 122 may also define an internal diameter, IDB, of rotary element 102.
[84] The inner surface 124 of the rotatable element 102, as defined by the bore 122, may have a pump gear 126 having a plurality of splines 128 or channels therein. The splines 128 can increase and directionally channel a fluid flow through the pump gear 126 while simultaneously assisting in the generation of a hydrodynamic bearing surface between the inner surface 124 and the impeller bearing 104.
[85] In a specific embodiment, gear pump 126 may have at least 1 spline per inch (FPI), such as at least 2 FPI, at least 3 FPI, at least 4 FPI, at least 5 FPI, at least 10 FPI , or even at least 20 FPI. Also, in an additional embodiment, pump gear 126 can be no more than 100 FPI, such as no more than 80 FPI, no more than 60 FPI, or even no more than 40 FPI.
[86] In a specific embodiment, the splines 128 may be oriented substantially parallel to the axis of rotation AR, or may be inclined thereto. The angle, AF, as defined by the angle between the splines 128 and the axis of rotation AR, may be at least 2 degrees, such as at least 3 degrees, at least 4 degrees, at least 5 degrees, at least 10 degrees, at least 15 degrees, or even at least 20 degrees. The selected angle, AF, can impact internal fluid flow through the pump gear 126, as will be apparent to one of ordinary skill in the art. Splines having a larger AF can create increased fluid flow through the pump gear 126, thereby increasing mixing efficiency by moving fluid in a vessel more quickly.
[87] The splines 128 may define a radial depth, DF, as measured by a distance the splines 128 extend radially outward from the inner surface 124 of the spinner 102. The splines 128 may extend radially outward from the surface interior 124 of rotary member 102. Flutes 128 may extend radially outward from interior surface 124 and terminate in a flute base 130. Flute base 130 may be formed from a flat surface spanning between two substantially parallel side walls 132 , 134.
[88] Alternatively, the flute base 130 may be formed by interfering between two angled side walls 132, 134 at a junction point. As will be apparent to one of ordinary skill in the art, flute base 130 may also comprise any other similar profile sufficient to generate a pressure gradient in magnetic impeller 100. For example, flute base 130 may be arcuate, triangular , crested or having any other similar geometric shape. It should be understood that pump gear 126 and splines 128 are optional. In an embodiment not illustrated, each of the components of the magnetic impeller 100, e.g., the inner surface 124, may be smooth, or otherwise free from corrugations, ridges, projections, or any combination thereof.
[89] Referring to Figure 5, an outer surface of the impeller bearing 104 may contain a plurality of splines 128. These splines 128 may be of any art-recognizable shape sufficient to generate a flow of fluid upon rotation. In a specific embodiment, the outer surface of impeller bearing 104 may have at least 1 spline per inch (FPI), at least 2 FPI, at least 3 FPI, at least 4 FPI, at least 5 FPI, at least 10 FPI, or even at least 20 FPI.
[90] The splines 125 may be oriented parallel to the axis of rotation, AR, or may be inclined thereto. The flute angle, AF, as defined by the angle between the flutes 50 and the axis of rotation AR, may be at least 2 degrees, at least 3 degrees, at least 4 degrees, at least 5 degrees, at least 10 degrees, at least minus 15 degrees, or even at least 20 degrees. The selected angle, AF, can affect fluid flow, as will be evident to a person of ordinary skill in the art will readily understand from the above discussion.
[91] In addition, the splines 128 may have a radial depth, DF, as defined by the distance the splines 128 extend radially inwardly from the outer surface of the impeller bearing 104. The splines 128 may extend radially inwardly from from the outer surface of the impeller bearing 104 and may terminate in a spline base 130. The splines 128 disposed on the impeller bearing 104 may have any similar number of features or aspects as the splines 128 disposed on the rotatable element 102.
[92] In one aspect, a ratio of splines 128 on impeller bearing 128 on rotating element 102 may be at least 1, at least 5, at least 10, at least 50, at least 100, at least 500, or even at least minus 1000. In another aspect, the ratio of splines 128 on impeller bearing 104 to splines 128 on rotary member 102 may be not greater than 1.0, not greater than 0.5, not greater than 0.2, not greater than 0.1, not greater than 0.05, not greater than 0.005, or even not greater than 0.0005.
[93] As illustrated in FIGS. 9A and 9B, the rotatable element 102 may be engaged with a column 132 of the impeller bearing 104. The bore 130 of the rotatable element 102 may have an internal diameter, and the column 132 of the impeller bearing 104 may have an external diameter, where the inner diameter of the rotary member 102 is greater than the outer diameter of the column 132 so that the column 132 can be freely inserted into the hole 130 along the axis of rotation AR. In such a manner, the impeller bearing 104 can slide towards and through the rotatable element 102 until the first impeller surface 134 makes contact and rests approximately flush against the rotatable element 102.
[94] In one specific aspect, column 132 may have an outside diameter, ODC, as measured perpendicular to the axis of rotation, AR. the inside diameter of the rotating member 102 may be not less than 1.01 ODC, such as not less than 1.02 ODC, not less than 1.03 ODC, not less than 1.04 ODC, not less than 1.05 ODC, not less than 1.10 ODC, not less than 1.15 ODC, not less than 1.20 ODC, or even not less than 1.25 ODC. Also, the inside diameter of the rotating element 102 may be no greater than 1.5 ODC, such as no greater than 1.45 ODC, no greater than 1.4 ODC, no greater than 1.35 ODC, no greater than 1, 3 ODC, not greater than 1.25 ODC, not greater than 1.2 ODC, or even not greater than 1.15 ODC. In such a way, an annular cavity 136 can be created in the space defined between the column 132 and the inner surface 124 of the rotatable element 102.
[95] In a specific embodiment, the annular cavity 136 may define a passage for the passage of a layer of fluid between the impeller bearing 104 and the rotating element 102. As the rotating element 2 is rotated about the axis of rotation, AR, the spline combination 128 may draw fluid through the annular cavity 136, providing a fluid bearing 138 therebetween. As such, the relative coefficient of kinetic friction, μk, as measured between the impeller bearing 104 and the rotating element 102, may be less than the relative coefficient of static friction, μs, as measured between the impeller bearing 104 and the rotating element. rotary 102. In one embodiment, a ratio of μs/μk may be at least 1.2, such as at least 1.5, at least 2.0, at least 3.0, at least 5.0, at least 10.0, at least 20.0, or even at least 50.0. However, in an additional embodiment, μs/μk can be no greater than 150.0, no greater than 125.0, or even no greater than 100.0.
[96] In another aspect, a fluid may be drawn through annular cavity 136 after formation of a relative pressure differential between a first opening 140 of fluid bearing 138 and a second opening 142 of fluid bearing 138. As such, a first pressure, P1, may be generated at the first opening 140 of the fluid bearing 138, and a second pressure, P2, may be generated at the second opening 142 of the fluid bearing 138. The resulting pressure gradient between P1 and P2 may cause flow of fluid. fluid through annular cavity 136.
[97] In a specific aspect, a P1/P2 ratio can be at least 1, at least 2, at least 5, at least 10, at least 15, or even at least 20. As the P1/P2 ratio P2 increases, the fluid flow rate in the annular cavity 126 may increase. This in turn can reduce μk and increase the operating efficiency of the magnetic impeller 100.
[98] In a specific aspect, the fluid bearing 138 may be adapted to provide a fluid flow layer, e.g. a hydrodynamic bearing, in the annular cavity 136 at a relative rotational speed between the impeller bearing 104 and the element. rotary 102 of less than 65 revolutions per minute (RPM), such as less than 60 RPM, less than 55 RPM, less than 50 RPM, less than 45 RPM, less than 40 RPM, less than 35 RPM, less than 30 RPM, less than 25 RPM, less than 20 RPM, less than 15 RPM, less than 10 RPM, or even less than 5 RPM. In one embodiment, the fluid bearing 138 may provide a fluid flow layer, e.g., a hydrodynamic bearing, into the annular cavity 136 at a relative rotational speed of not less than 0.1 RPM, such as not less than 0.5 RPM, not less than 1 RPM, or even not less than 2 RPM.
[99] In a specific embodiment, the annular cavity 136 may have a minimum radial thickness, TACMIN, as measured at a first location in the annular cavity 136 in a direction perpendicular to the axis of rotation, AR, and a maximum radial thickness, TACMAX, as measured at a second location in annular cavity 136 in a direction perpendicular to the axis of rotation, AR. In a specific embodiment, a TACMIN/TACMAX ratio can be at least 1.1, at least 1.2, at least 1.3, at least 1.4, at least 1.5, at least 1.6, at least at least 1.7, at least 1.8, at least 1.9, or even at least 2.0. A large ratio of TACMIN/TACMAX may indicate the use of flutes 128 having a large DF, for example flutes 128 extend a greater distance from the interior surface 124. This can facilitate increased fluid layer flow between the element. 102 and impeller bearing 104, which in turn can reduce the coefficient of kinetic friction, μk.
[100] In a specific embodiment, one or more components of impeller bearing 104 may include a polymer layer formed along an outer surface thereof. Exemplary polymers may include a polyketone, polyaramid, polyimide, polyetherimide, a polyphenylene sulfide, a polyethersulfone, a polysulfone, a polyphenylene sulfone, a polyamideimide, ultra high molecular weight polyethylene, a fluoropolymer, a polyamide, a polybenzimidazole, or any combination thereof.
[101] In one example, the polymer may include a polyketone, a polyaramid, a polyimide, a polyetherimide, a polyamideimide, a polyphenylene sulfide, a polyphenylene sulfone, a fluoropolymer, a polybenzimidazole, a derivative thereof, or a combination thereof. of the same. In a specific example, the thermoplastic material includes a polymer, such as a polyketone, a thermoplastic polyimide, a polyetherimide, a polyphenylene sulfide, a polyether sulfone, a polysulfone, a polyamide imide, a derivative thereof, or a combination thereof. In a further example, the polymer may include a polyketone, such as polyether ether ketone (PEEK), polyether ketone, polyether ketone ketone, polyether ketone ether ketone, a derivative thereof, or a combination thereof. In a further example, the polymer may be ultra high molecular weight polyethylene.
[102] An example fluoropolymer may include a fluorinated ethylene propylene (FEP), a PTFE, a polyvinylidene fluoride (PVDF), a perfluoroalkoxy (PFA), a terpolymer of tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride (THV), a polychlorotrifluoroethylene (PCTFE), an ethylene tetrafluoroethylene (ETFE) copolymer, an ethylene chlorotrifluoroethylene (ECTFE) copolymer, or any combination thereof. The inclusion of the polymer layer on the outer bearing surface can increase the longevity of the magnetic impeller 100, and can additionally decrease friction therein. Furthermore, the polymer layer can increase the relative inertia of the impeller bearing 104 within a fluid.
[103] In a specific embodiment, the interior surface 124 of the spinner 102 may additionally include a polymer layer to facilitate translation of the spinner 102 in the column 132 and increase inertia. The polymer selected may at least partially include, for example, a polytetrafluoroethylene (PTFE), a polyvinylidene fluoride (PVDF), a polyaryletherketone (PEEK), or any combinations thereof.
[104] As indicated in Figure 6, the spinner 102 may further include a magnetic member 144 at least partially disposed in a cavity 146 of the spinner 102. The magnetic member 144 can include any magnetic, partially magnetic, or ferromagnetic material. Magnetic element 144 need only be able to couple with a magnetic field provided by a drive magnet (not shown). Accordingly, in a specific embodiment, the magnetic element 144 may be ferromagnetic and selected from the group consisting of a steel, an iron, a cobalt, a nickel, and a rare earth magnet. In a further embodiment, the magnetic element 144 may be selected from any other magnetic or ferromagnetic material as would be readily recognizable in the art. In specific embodiments, the magnetic element 144 may be a neodymium magnet. In additional specific embodiments, the magnetic drive (illustrated, for example, in Fig. 57) may include a magnetic magnet. In very particular embodiments, both the magnetic element in the rotating element and the magnetic element in the magnetic drive may include neodymium magnets. A specific advantage of certain embodiments of the present disclosure is the discovery that at least one of and even both of the magnetic element in the rotating element and the magnetic element in the magnetic drive can have a magnetic coupling which greatly reduces the risk of decoupling during operation. Furthermore, in certain embodiments, the blades may be adapted to provide lift to the rotating element that can overcome the increased friction between the rotating element and the surface on which it is rotating due to the stronger magnetic coupling.
[105] In a specific embodiment, the magnetic element 144 may have a mass, MME, in grams, and the driving magnet may have a power, PDM, as characterized by its magnetic flux density, and as measured in teslas. In a specific embodiment, a PDM/MME ratio can be at least 1.0 g/tesla, such as at least 1.2 g/tesla, at least 1.4 g/tesla, at least 1.6 g/tesla, at least 1.8 g/tesla, at least 2.0 g/tesla, at least 2.5 g/tesla, at least 3.0 g/tesla, or even at least 5.0 g/tesla. In a specific embodiment, as the mass of the magnetic element 144 increases, the power required from the driving magnet may decrease.
[106] In a further embodiment, the magnetic element 144 may further comprise a plurality of magnetic elements arranged around the axis of rotation AR of the rotating element 102.
[107] In a specific embodiment, a cover 148 may be placed in an opening of the cavity 146 to form an interference fit and contain the magnetic element 144 in the cavity 146. In another embodiment, the cover 148 may be hermetically sealed to the opening of the cavity. cavity 146. In yet another embodiment, cap 148 may be threadedly engaged with cavity opening 146 by a corresponding threaded structure. In another embodiment, cover 148 may include a gasket that forms an interference fit with the opening of cavity 146. The gasket may include a gasket extending around cover 148 or any number of gaskets substantially parallel therewith. . The gasket may also be angled relative to the outer surface of the cap 148. In yet another embodiment, the cap 148 may be overmolded over the cavity opening 146. In yet a further embodiment, the cap 148 may be sealed to the cavity opening 146. by any other easily recognizable method of joining two elements.
[108] In a further embodiment, cover 148 may include a spacer 150. Spacer 150 may extend from cover 148 to engage with and secure magnetic member 144. Spacer 150 may be sized to substantially fill the volume in the cavity after the magnetic element 144 has been disposed thereon. In a specific embodiment, spacer 150 may be integral with cap 148.
[109] In one embodiment, the spacer 150 or cap 148 may be formed of a high density material that is substantially incompressible. In such a way, the spacer 150 can be sized to fit the cavity to generate compression between the cover 148 and the magnetic element 144. In another embodiment, the spacer 150 can be a compressible material that is sized to be larger than the cavity. . Upon application of the cap 144 to the cavity 146, the spacer 150 can compress, generating increased security and stability of the magnetic element 144.
[110] The compression between the spacer 150 and the magnetic element 144 can reduce relative vibration of the magnetic element 144 in the cavity, while simultaneously reducing unwanted vibration and oscillation of the rotating element 102 during operation. Additionally, the reduced vibration of the magnetic element 144 can facilitate increased engagement of the magnetic element 144 with an external drive magnet (not shown). This, in turn, can increase the efficiency of the magnetic impeller 100 by reducing unwanted disconnection between the magnetic element 144 and the driving magnet (not shown).
[111] Referring again to Figures 1 and 2, the magnetic impeller 100 may further include a plug 152. The plug 152 may be adapted to retain the rotating element 102 in the impeller bearing 104. The plug 152 may include an axial element substantially hollow adapted to engage with column 132 of impeller bearing 104.
[112] In a specific aspect, the impeller bearing 104 may include a cutout extending into the column 132. The axial plug member 152 may be inserted into the cutout until a portion of the column 132 makes contact with a portion of the plug 152 .
[113] In a specific aspect, the plug 152 may form an interference fit with the column 132. In this and other embodiments, the plug 152 may be removable from the column 132. After the rotating element 102 has been inserted over the impeller 104, plug 152 may be inserted into column 132 so as to prevent rotatable member 102 from axially decoupling therefrom.
[114] In addition, plug 152 may include a plurality of holes 154 adapted to block large debris in fluid from entering fluid bearing 138.
[115] As illustrated in Figure 8, in operation fluid may be drawn through plug 152 and into fluid bearing 138. Plug 152 may include one or more holes 154 adapted to allow fluid to pass therethrough. In such a way, the fluid can pass between the rotating element 102 and the impeller bearing 104 and can be dispersed in a radially outward direction.
[116] Figure 10 illustrates an embodiment according to an alternative magnetic impeller 200 that includes blades 206 axially decoupled from the rotatable element 202. The magnetic impeller 200 may include the rotatable element 202 rotatably decoupled from an impeller bearing 204 along of an axis of rotation, AR, and axially decoupled therefrom. Rotatable element 202 may act as an intermediary between impeller bearing 204 and vanes 206. Rotatable element 202 may rotate relative to impeller bearing 204. Rotatable element 202 may define a first surface 210 and a second surface 212. A mullion 214 can extend from the first surface 210 of the rotatable element 202 and can extend along the central axis of rotation 208 a distance HP. The mullion 214 may have any geometric arrangement, but preferably comprises a generally cylindrical shape having a diameter, DP.
[117] The rotatable element 202 may include a cavity in which a magnetic element 216 may be received. Magnetic element 216 can include any magnetic, partially magnetic or ferromagnetic material. Magnetic element 216 need only be able to couple with a magnetic field provided by a drive magnet (not shown). Accordingly, the magnetic element 216 may be ferromagnetic and selected from the group consisting of a steel, an iron, a cobalt, a nickel, and a rare earth magnet. Furthermore, the magnetic element 216 may be selected from any other magnetic or ferromagnetic material as would be readily recognizable in the art.
[118] In a specific embodiment, the magnetic element 216 may have a mass, MME, in grams, and the driving magnet may have a power, PDM, as characterized by its magnetic flux density and measured in teslas. A PDM/MME ratio can be at least 1.0 g/tesla, at least 1.2 g/tesla, at least 1.4 g/tesla, at least 1.6 g/tesla, at least 1.8 g /tesla, at least 2.0 g/tesla, at least 2.5 g/tesla, at least 3.0 g/tesla, or even at least 5.0 g/tesla. As the mass of the magnetic element 216 increases, the power required of the driving magnet to remain magnetically coupled to the magnetic element 216 may decrease.
[119] The magnetic element 216 may further comprise a plurality of magnetic elements arranged around the central axis of rotation 208 of the rotary element 102. For example, as illustrated in Figure 10, the rotary element 102 may house two magnetic elements 216 arranged in a row. rotational symmetry around the mullion 214.
[120] According to one or more embodiments, the blades 206 may include a hub 218 extending between the blades 206.
[121] In a specific embodiment, the blades 206 may define a mass, FB, with the resultant force oriented substantially parallel to the axis of rotation, AR. The 206 blades can also be adapted to generate a lifting force, FL. In a specific aspect, the blades may be adapted to translate in the opposite direction from the rotating element 202 when the magnitude of FL reaches a magnitude that is greater than the magnitude of FB.
[122] In a specific embodiment, the mullion 214 may extend from the rotatable element 202 along the axis of rotation, AR. The mullion 214 may have a height, HP, where the blades 206 are rotationally coupled to the mullion 214 along HP. Additionally, the hub 218 of the blades 206 may have a height, HH, as measured in a direction parallel to the axis of rotation, AR. In a specific embodiment, the blades 206 may be adapted to translate along the riser 214 by a distance, HT, where HT is equal to the difference between HP and HH.
[123] In a specific embodiment, the magnetic impeller may further include a plug 220. The plug 220 may be adapted to retain the blades 206 on the mullion 214. The plug 220 may include a substantially hollow axial member adapted to engage with the mullion 214. The axial element may be inserted into the mullion 214 until a portion of the mullion 214 makes contact with a portion of the plug 220.
[124] In a specific aspect, the plug 220 can form an interference fit with the mullion 214 so that the plug 220 can be removed from the mullion 214. After the blades 206 have been inserted over the mullion 214, the plug 220 can be inserted into the mullion 214 so as to prevent the blades 206 from axially decoupling from the mullion 214.
[125] As illustrated in Figure 10, the mullion 214 and hub 218 may individually contain one of a radial protrusion 222 and a radial recess 224. As illustrated in Figure 11, the hub 218 may contain a protrusion 222 and the mullion 214 may contain a radial recess 224. Conversely, in an embodiment not illustrated, the hub 218 may contain a radial recess 224 and the upright 214 may contain a protrusion 222. The protrusion 222 and the radial recess may extend the entire length of the hub 218 and the full length of mullion 214, allowing relative axial sliding between hub 218 and mullion 214 over a distance, HLEV. This distance, HLEV, in turn can define a maximum obtainable height of levitation that can be displayed during rotational mixing operation.
[126] In another embodiment not illustrated, the mullion 214 may have a non-symmetrical cross section. Hub 218 may have a cross-section substantially identical to mullion 214. In such an embodiment, hub 218 may remain rotationally coupled to mullion 214 during rotation, however, hub 218 may remain axially uncoupled from mullion 214 in a direction parallel to the axis of rotation. central rotation 208. This may allow the blades 206 to translate along the mullion 214 while simultaneously coupling the blades 26 rotationally to the mullion 214.
[127] Referring to Figures 11 and 12, blades 206 can translate along mullion 214 by a distance, HLEV, while remaining rotationally coupled to mullion 214. As blades 206 are induced along central axis of rotation 208 , the blades 206 can be adapted to translate parallel thereto, or levitate away from the first surface 210 of the rotatable element 202. The levitation of the blades 206 can allow increased mixing of the fluid by optimizing the location of the blades 206 away from an inner surface 226 of a vessel 228.
[128] In a specific aspect, the 206 blades can be adapted to levitate during operation at a speed less than 900 revolutions per minute (RPM), such as at a speed less than 800 RPM, less than 700 RPM, less than 600 RPM, less than 500 RPM, less than 400 RPM, less than 300 RPM, less than 200 RPM, less than 100 RPM, less than 75 RPM, or even less than 65 RPM. The blades 206 may be further adapted to levitate during operation at a speed of at least 10 RPM, such as at least 20 RPM, at least 30 RPM, at least 40 RPM, or even at least 50 RPM.
[129] During levitation of the blades 206, a flow of fluid may be allowed through the fluid bearing formed between the hub 218 and the upright 214. As illustrated in Figure 13, and in accordance with one or more embodiments described herein, the fluid can be pulled through plug 220 and into fluid bearing 230. Fluid can pass between rotating member 202 and impeller bearing 204 and can be dispersed out of fluid bearing by radial notches 232.
[130] The magnetic impeller 200 may be adapted to provide improved mixing efficiency by axially decoupling the blades 20 from the rotating element 202. In other words, the blades 206 may be capable of axial translation away from the rotating element 202. while simultaneously maintaining rotational engagement with it. In a specific aspect, decoupling the blades 206 from the rotating element 202 may allow the blades 206 to translate toward the center of the vessel into which the magnetic impeller 200 is positioned, thereby reducing friction between the blades 206. and an inner wall of the vessel, while simultaneously allowing for improved magnetic coupling between the magnetic element 216 and the driving magnet. In that regard, decoupling the blades 206 can increase mixing efficiency.
[131] Figure 14 illustrates an alternative magnetic impeller 300 that can be adapted to transition between a first configuration with a narrower profile and a second configuration with a wider profile. In this way, the magnetic impeller 300 can be inserted into a vessel having a narrow opening and expand after being inside the vessel to a second configuration that provides increased mixing efficiency characteristics.
[132] In a specific embodiment, the magnetic impeller 300 may generally include a plurality of blades 306, a rotating element 302, a retaining element 304 and a magnetic element 308.
[133] The rotatable element 302 may include a body 310 and a mullion 312 that can extend from a surface of the body 310. In specific embodiments, the mullion 312 may extend generally perpendicular to a longer length of the body 310.
[134] At least one of the plurality of blades 306, and in specific embodiments, at least two of the plurality of blades 306, may each have a hub 314 adapted to engage with mullion 312. For example, as illustrated in Figure 14, the hub 314 may define an opening 316. Opening 316 may have a diameter that is larger, and preferably slightly larger, than the diameter of mullion 312. Retaining member 304 may then be coupled to mullion 312 to retain blades 306 rotatably around of the mullion 314 and thereby engaged with the body 310.
[135] The magnetic impeller 300 may have a first configuration and a second configuration so that in the first configuration the magnetic impeller can be adapted to be inserted through an opening in a vessel and cannot be inserted through the opening in the second configuration. For example, with reference to Figure 15, the magnetic impeller of Figure 14 is illustrated in a first configuration, as seen from a top view. in the first configuration, a first blade 318 and a second blade 320 may generally align rather than intersect. With generally aligned blades 318 and 320, the magnetic impeller may have a narrower profile than in configurations where blades 318 and 320 extend in different directions. Therefore, the magnetic impeller may be able to be inserted through a vessel opening when in a first configuration.
[136] Figure 16 illustrates a magnetic impeller 300 during transformation between the first configuration and the second configuration. Figure 17 illustrates a magnetic impeller in the second configuration. The second configuration may be the desired configuration for operation of the magnetic impeller 300. The magnetic impeller 300 may transform into the second configuration from the first configuration by a relative rotation of the first or second blades 318 and 320 about the mullion 312.
[137] For example, the first or second blades 318 and 320 can be configured to partially rotate freely relative to each other so that the first blade 318 can partially rotate without affecting the position of the second blade 320 or physically engaging the second blade. 320. Similarly, the first or second blades 318 and 320 can be configured to partially rotate freely with respect to the housing 302 so that the first or second blades 318 and 320 can partially rotate without affecting the position of the housing 302. first blade 318, second blade 320, and housing 302 may all be generally aligned in the first configuration and partially pivot to a second configuration where the first blade 318, second blade 320, and housing 302 can extend at an angle to each other. As will be discussed in more detail below, the free rotation of the blades 318 and 320 and housing 302 in relation to each other can be partial, for example, by a series of corresponding flanges 322, 323 and 326 which limit the relative free rotation. Thus, after the blades 318 and 320 and housing 302 have fully transformed to the second configuration, the corresponding flanges 322, 324 and 326 can engage and the blades 318 and 320 and housing 302 can rotate together and maintain their relative positional relationship in the second configuration.
[138] When the magnetic impeller 300 is in the second configuration, the magnetic impeller may be adapted to not fit through a vessel opening. For example, in the second position, the blades 318 and 320 can rotate, in relation to each other, so that the blades 318 and 320 extend in a different direction from the axis of rotation. The blades 318 and 320 may have a length that is greater than an opening in the vessel into which the magnetic impeller is adapted to be inserted. As such, when the blades may extend in a different direction in the second configuration, the profile of the magnetic impeller may be such that the magnetic impeller may not fit through the same opening that the magnetic impeller would fit through in the first configuration.
[139] Magnet impeller 300 may include a single blade, or a plurality of blades as illustrated in Figure 14. In a specific embodiment, magnetic impeller 300 may have at least 1 blade, such as at least 2 blades, at least 3 blades or even at least 4 paddles. The number of blades 306, and their relative size can be molded depending on the size and shape of the vessel and particularly the vessel opening. The plurality of blades 306 may include a first blade 318 and a second blade 320. Each of the first blade 318 and second blade 3290 may be adapted to engage with the mullion 312 in a manner as described above. Therefore, the first blade 318 and the second blade 320 can be adapted to rotate about a common axis. Furthermore, as illustrated in Figures 14 to 17, the first blade 318 and the second blade 320 can be adapted to rotate in different planes. For example, the first blade 318 may be arranged above the second blade 320.
[140] As discussed above, at least one of the first blade 318 and second blade 320 are partially free to rotate about the mullion 312 and in relation to each other. When the magnetic impeller transforms to the second configuration, the first blade 318 or the second blade 320 may partially rotate and then engage with each other and with the rotating element 302. For example, Figure 18 illustrates a close-up view of the mullion 312. , rotary member 302 and blades 318 and 320, and a plurality of separate flanges 322, 324, and 326 on each of first blade 318, second blade 320, and retaining member 304 in the first configuration. As the blades 318 and 320 rotate to the second configuration, corresponding flanges 322, 324 and 326 may engage and thereby rotate together rather than freely rotating in relation to each other as illustrated in Figure 19. For example, flanges 322 in the first blade 318 may be adapted to engage with a mating flange 324 on retaining member 304 after the desired relative position between the first and second blades 318 and 320 is reached. The desired relative position between the first and second blades 318 and 320 and the rotatable element 302 can be molded as desired by altering the relative position of the correspondingly engaging flanges 322, 324 and 326.
[141] Referring again to Figure 14, the rotatable element 302 can be adapted to retain the magnetic element 308. The rotatable element 302 can be of any desired shape. In specific embodiments, the rotatable element 302 may have a profile that is smaller than an opening in a vessel so that the magnetic impeller 300 can be inserted into the vessel through the opening as described in detail above.
[142] In another embodiment, as, for example, illustrated in Figures 20 to 22, the rotatable element 302 may have a generally disk-shaped profile. As used herein, the term "generally disc-shaped" refers to a deviation from a circular shape, when viewed from a top view, by no more than 20% at any location, such as no more than 15% at any location, not more than 10% at any location, not more than 5% at any location, or even not more than 1% at any location. A disc-shaped rotating element 302 can be adapted to impart minimal mixing action in a nearby fluid. In this way, mixing can be facilitated almost exclusively by the paddles 318. This can be particularly advantageous for mixing operations including delicate fluids or fluids that require a specific mixing action. When viewed from a side view (Figures 21 and 22), the disc-shaped spinner 302 may have an arched or flat bottom surface.
[143] In additional embodiments, as, for example, illustrated in Figures 20 to 22, the rotatable element 302 may enclose magnetic elements therein. The magnetic element can be any of those described herein and in specific embodiments can include elongate magnets and/or disc magnets. It should be understood that the disc-shaped rotating member 302 may be used with any paddle and/or vessel configuration described herein.
[144] As illustrated in Figures 21 through 24, in certain embodiments, the rotating element 302 may include a contact flange 328. The contact flange 328 may be disposed at least on the lower surface of the rotating element 302. The contact flange 328 may be parabolic or otherwise arcuate in shape and provide a point of contact between the magnetic impeller and the vessel when the magnetic impeller 300 is engaged and rotating. Contact flange 328 can reduce friction generated during rotation of magnetic impeller 300 by reducing the amount of surface area in contact with the vessel during operation. In addition, the symmetry of the contact flange 328, in either configuration, can improve the stability of the rotating member 302 during operation.
[145] Contact flange 328 can be any desired shape. In specific embodiments, the contact flange 328 may be parabolic or arcuate in shape. Also, as illustrated in Figure 23, the contact flange 328 may extend around the width or circumference of the rotating element 302. In other embodiments, as illustrated in Figure 24, the contact flange 328 may extend along the length of the element. rotator 302. It has been found that a contact flange 328 extending the length of the rotatable element 302 can greatly reduce vibration of the magnetic impeller 300 during operation. in certain additional embodiments, as particularly illustrated in Figure 22a, the contact flange may extend from the center towards the outer edge of the rotating member in two directions. In other embodiments, as particularly illustrated in Figure 22b, the contact flange 328 may extend from the center towards the outer edge of the rotary member 302 in four directions. Therefore, in certain embodiments, contact flange 328 may extend from the center toward the outer edge of rotary member 302 in at least two, at least three, or even at least four directions.
[146] Referring now to Figure 22c, in certain embodiments, the rotatable element 302 may include an arcuate top surface 29 extending from the outer edge of the rotatable element 302 toward axis 312. In specific embodiments, the arcuate top surface 329 can assist in preventing particulate matter from settling on the surface of the rotating element 302.
[147] Referring again to Figure 14, the rotatable element may further include one or more support elements 330 and 332. One or more support elements 330 and 332 may be adapted to assist the magnetic impeller 300 in maintaining a vertical position when inserted into a vase. For example, during insertion into a vessel, if the magnetic impeller 300 contacts the bottom of the vessel in a position other than a generally vertical position, the support elements 330 and 332 may facilitate translation or rolling of the magnetic impeller 300 to a generally vertical position. vertical. In addition, support elements 330 and 332 can help provide stability to the magnetic impeller 300 during rotation. For example, during operation, support elements 330 and 332 can help lower the center of gravity of magnetic impeller 300 to provide stability. In addition, the support elements 330 and 332 can provide an anti-rolling feature, where if the magnetic impeller 300 starts to vibrate too much, the support elements 330 and 332 can facilitate keeping the magnetic impeller 300 in an upright position and discourage or prevent the magnetic impeller 300 from rolling.
[148] Support elements 330 and 332 can be of any desired shape. In specific embodiments, support elements 330 and 332 may include an arcuate surface projecting from rotatable element 302. The arcuate surface may be ring-shaped, or semicircular-shaped, or any other shape that assists magnetic impeller 300. maintain a vertical position during insertion or operation.
[149] In a very specific embodiment, the magnetic impeller 300 may include more than one support element 330 and 332. For example, as illustrated in Figure 14, the magnetic impeller 300 may include a first support element 330 and a second element. support element 332. The first support element 330 may be disposed above the second support element 332. The first support element 330 may extend further from the rotatable element 302 than the second support element 332. The first and second support elements 330 and 332 may have the same general shape or may have a different shape.
[150] Magnetic impeller 300 may further include a magnetic element 308. In general, magnetic element 308 may be disposed in any arrangement on rotatable element 02. In specific embodiments, magnetic element 308 may be substantially centered on body 310 so that that the magnetic impeller 300 can be substantially symmetrical.
[151] In a specific aspect, as seen in Figure 14, the rotating element 302 may include a cavity 334 for placement of the magnetic element 308. The cavity 334 may include an opening to allow installation of the magnetic element 308 therein. Cavity 334 may be molded to receive magnetic element 308 and may include a cap 336 to form a substantially liquid-tight seal of magnetic element 308 therein. In certain embodiments, cavity 334 may include more than one opening 334 and include a corresponding number of caps 336.
[152] In a specific embodiment, the cover 336 may be placed in the opening of the cavity 334 to form an interference fit and secure the magnetic element 308 in the cavity 334. In another embodiment, the cover 336 may be hermetically sealed in the opening of the cavity. 334. In yet another embodiment, cap 336 may be threadedly engaged with the opening by a corresponding threaded structure. In another embodiment, cap 336 may include a gasket 338 that forms an interference fit with cavity opening 334. In yet another embodiment, cap 336 may be overmolded with cavity opening 334. In yet another embodiment, the cap 336 may be sealed at the opening by any other readily recognizable method of joining two elements.
[153] The magnetic impeller 300 may further include a vessel 340. The magnetic impeller 300 may be used with any size or shape of vessel. Referring to Figures 25 through 28, in specific embodiments, vessel 340 may have an opening 342 that is smaller than the cross-sectional area of body 344 of vessel 340. In very specific embodiments, vessel 340 may be a carboy. As used herein, a "carboy" refers to any vase having a neck that is narrower than the body of the vase, as illustrated in Figures 25 to 28. As illustrated in Figures 25 to 28, the vase 340 may be of a generally cylindrical. In other embodiments, vessel 340 may be of any shape, such as rectangular, cylindrical, polygonal, or any other shape suitable for retaining fluid therein.
[154] As shown in Figure 25 and discussed above, the magnetic impeller 300 may have a blade length that may be longer than the opening 342 of the vessel 340. Thus, the magnetic impeller 300 cannot be inserted into the vessel 340 with the blades fully deployed and positioned at an angle to each other. As shown in Figure 26, when the magnetic impeller 300 is the first configuration, the magnetic impeller 300 can be inserted into the vessel 340 with the blades pointing through the opening 342 of the vessel 340. When the blades are aligned, the magnetic impeller 300 can adapt through opening 342. Figure 27 illustrates magnetic impeller 300 falling through vessel 340. As magnetic element 308 is heavy and disposed in the lower half of vessel 340, magnetic impeller 300 tends to self-orient to the vertical position. correct as it is falling through the body 344 of the vessel 340. This effect is even more pronounced when dropping the magnetic impeller into a vessel 340 filled with fluid. Figure 28 illustrates the magnetic impeller in the second configuration and in operation at the base 346 of the vessel 340. As seen in the second operational configuration, the blades and rotating element are spaced at an angle to each other and thereby intersect. The second configuration may have a higher mixing efficiency than the first configuration. For example, separating the paddles and rotating element from each other so that the paddles and rotating element cross each other imparts improved mixing action on the fluid being mixed by increasing surface area contact with the fluid and improving fluid flow efficiency. through and around the magnetic impeller.
[155] In a specific embodiment, the blades 306 or the magnetic impeller may be injection molded using a polymer material. The blades 306 may also be formed by any other suitable construction method, including, for example, molding, bending, extrusion, twisting, machining, or a combination thereof. Furthermore, the blades or magnetic impeller may comprise any material suitable for use in fluidic mixing. For example, the blades may comprise a polymer material, a metallic material, an epoxy, ceramic, glass, a fibrous material such as wood, or any combination thereof. In specific embodiments, elements of the magnetic impeller may include the rotating element, vanes and plugs, all of which may contain a polymeric material, and preferably contain a polymeric material that will be generally chemically inert with the specific fluid being mixed.
[156] In a specific embodiment, the blades 306 may comprise a flexible material. In a specific aspect, a flexible material may allow the blades 306 to further compress during insertion of the magnetic impeller into the vessel 340. In this regard, the magnetic impeller may be used in vessels 340 having an even smaller opening. Of specific importance in this regard, the blades 306 may have a minimum compressible width, WBMIN, as defined by the tangential distance between the two most distant points thereof. In a specific modality a WB/WBMIN ratio can be not less than 1.05, not less than 1.1, or even not less than 1.2.
[157] To facilitate a flexible blade 306, in specific embodiments, the blades 306 may be constructed at least partially of a material having a Young's modulus not greater than 5 GPa, such as not greater than 4 GPa, not greater than 3 GPa, not greater than 2 GPa, not greater than 1 GPa, not greater than 0.75 GPa, not greater than 0.5 GPa, not greater than 0.25 GPa, or even not greater than 0.1 GPa. In additional embodiments, the 306 blades may be constructed from a material having a Young's modulus of not less than 0.01 GPa.
[158] As the Young's modulus decreases, the relative flexibility of the blades 306 may increase, however, the ability for the blades 306 to maintain structural rigidity during mixing may decrease. Accordingly, the blades 306 may be constructed at least partially of a material having a low Young's modulus (eg, 0.05 GPa) and partially of a material having a relatively high Young's modulus (eg, 7.0 GPa).
[159] In specific embodiments, material having a relatively high modulus may be positioned along a central portion of blade 306, and may extend substantially along the length thereof, while material having relatively low modulus may be positioned along the sides of the blade 306.
[160] In specific embodiments, the blades 306 may at least partially comprise a silicone. In additional embodiments, the blades 306 may be silicone based. In that regard, the blades 306 may be adapted to curve or flex and accommodate entry into a vessel having a relatively narrow opening. Of course, it should be understood that the blades 306 may comprise any other materials having a relatively low modulus of elasticity (as described above), and that this exemplary embodiment should not be interpreted as limiting the scope of the present disclosure.
[161] Referring now to Figure 29, which illustrates a top view of one embodiment of a blade design, blades 306 may have a central hub 314 and a blade extending in generally opposite directions. As illustrated the blade may have a first section 348 and a second section 350, where the first section 348 extends from the hub in a different direction than the second section 350. As illustrated, the first and second sections 348 and 350 may have the same general shape, and may be rotationally symmetric.
[162] Referring now to Figure 30, which illustrates a top view of another embodiment of a blade design, the first and second sections 348 and 350 may be rotationally symmetrical, but not identical. Also, the maximum width of the WBMAX blade can be greater than the maximum width of the 314 hub.
[163] In a specific embodiment illustrated in Figures 31 and 32, the blades 306 may have a non-rectilinear cross-section. For example, a major surface 352 of blades 306 may be an arcuate surface extending between a leading edge 354 and a trailing edge 356. The arcuate surface may be concave or convex with respect to the blade 306. In this regard, the arcuate surface may extend outward (i.e., away from) from a tangent line drawn between the leading edge 354 and the trailing edge 356 or may extend inward (i.e., towards) to a tangent line drawn between the leading edge 354 and trailing edge 356. This arcuate surface may be adapted to generate lifting forces in a fluid and push fluid down by a water hammer effect, thereby improving circulation beneath the blades.
[164] Referring to Figure 31, the non-rectilinear blades 306 may have a larger average surface, as defined by the direct angle between the leading edge 354 and the trailing edge 356. The non-rectilinear blades 306 may have an angle of attack, AA , as measured by the shaped angle between the mean major surface and the central axis of rotation of the blades 306. In specific embodiments, AA may be at least 20 degrees, such as at least 30 degrees, at least 40 degrees, at least 50 degrees, at least at least 60 degrees, at least 70 degrees, at least 80 degrees, or even at least 85 degrees. In additional embodiments, AA can be no greater than 85 degrees, such as no greater than 80 degrees, no greater than 70 degrees, no greater than 60 degrees, no greater than 50 degrees, or even no greater than 40 degrees. In even more particular embodiments, AA may also be in a range between any of the values described above.
[165] As AA increases, the lift generated by the blades 306 can correspondingly increase, generating increased lift characteristics of the blades 306 in a fluid. Specifically, as the angle of attack, AA increases from 90 degrees to 135 degrees, the lift characteristics of the 306 blade may increase. It should be understood that conversely, as the angle of attack AA increases from 135 degrees to 180 degrees, the lift characteristic of the blade 306 may decrease. However, although the lift characteristic of the blades 306 may decrease in a range between 135 degrees and 180 degrees, the mixing efficiency of the magnetic impeller may increase as the relative surface area of the blades 306 contacting the fluid increases, thereby increasing the relative force exerted by the blade 306 on the fluid.
[166] Thus, in a more particular embodiment, AA may be in a range between and including 105 degrees to 130 degrees. In yet a more specific embodiment, AA may be in a range between and including 115 degrees and 130 degrees.
[167] Referring now to Figure 32, the blades 306 may also define an angle of curvature, AC, as defined by an outside angle formed by the intersection of the tangents of leading edge 354 and trailing edge 356. In specific embodiments, AC may be greater than 5 degrees, such as greater than 10 degrees, greater than 20 degrees, greater than 30 degrees, greater than 40 degrees, greater than 50 degrees, or even greater than 60 degrees. In additional embodiments, AC can be less than 100 degrees, such as less than 90 degrees, less than 80 degrees, less than 70 degrees, less than 60 degrees, less than 50 degrees, less than 40 degrees, or even less than 30 degrees. In even more particular embodiments, AC may also be in a range between any of the values described above. As AC increases, the lifting forces generated by the blades 306 in the fluid can increase. This in turn can lead to increased fluid mixing efficiency.
[168] Referring to Figure 33, which illustrates a cross section of a different embodiment of a blade design, the blades 306 may have a straight cross-section as measured perpendicular to the major surface 352 of the blade 306. In such an embodiment, the blades 306 may have an angle of attack, AA, as measured by the shaped angle between the major surface 352 of the blade 306 and the central axis of rotation of the rotary member 302. The angle of attack is a lifting parameter. As the angle of attack increases, the ability of the blades 306 to generate a lifting force in a fluid can increase. Correspondingly, as the angle of attack decreases, the ability of the blades 306 to generate a lifting force in a fluid may decrease.
[169] In paddle embodiments having a straight cross-section, AA may be at least 20 degrees, such as at least 30 degrees, at least 40 degrees, at least 50 degrees, at least 60 degrees, at least 70 degrees, at least 80 degrees degrees, or even at least 85 degrees. In additional embodiments, AA can be no greater than 85 degrees, such as no greater than 80 degrees, no greater than 70 degrees, no greater than 60 degrees, no greater than 50 degrees, or even no greater than 40 degrees. In even more particular embodiments, AA may also be in a range of any of the values described above.
[170] Referring to Figure 34, which illustrates a cross-section of an additional embodiment of a blade design, blades 306 may individually comprise a distal flange 358 extending from blade 306 at its distal end. Distal flange 358 can facilitate increased fluid agitation and mixing of the fluidic ingredients of the fluid. Distal flange 358 may extend generally perpendicular to major surface 352 of blade 306, or at any other suitable or desirable angle to effect desired mixing. Distal flange 358 can be shaped straight or non-straight, as desired to increase fluid flow and alter the lift and mixing characteristics of paddle 306.
[171] Referring now to Figure 35, which illustrates a cross-section of yet another embodiment of a blade design, the blade 306 may have a larger arcuate surface 352 over the top surface between the leading edge 354 and the trailing edge 356. In additional embodiments, the blade 306 may have at least one generally linear surface on a second major surface 360 which is disposed opposite the major arcuate surface 352. In general, the second major surface 360 may be closer to the bottom of the vessel than the arcuate major surface 352. In this regard, during rotational operation, the second major surface 360 may push, or force, fluid to the bottom of the vessel, generating a lifting action. Furthermore, in certain embodiments, pushing the fluid to the bottom of the vessel can further enhance the suspension characteristics in the fluid.
[172] Referring now to Figures 36 and 37, which illustrate a cross-section and top view of another embodiment of a blade design, the blade 306 may have an extendable or deployable leading edge 362. The extendable or deployable leading edge 362 may be deployed during rotation when a sufficient amount of force is applied by the fluid to extend the leading edge 362.
[173] In specific embodiments, the Extendable or Deployable Advanced Edge 362 can begin to deploy at rotational speeds less than 1 RPM. In other embodiments, the 362 Deployable or Extensible Advanced Edge can start deploying at 1 RPM, at 5 RPM, or even at 10 RPM.
[174] In certain embodiments, the Extendable or Deployable Leading Edge 362 can be fully deployed, or fully extended, at a rotational speed not greater than 200 RPM, such as not greater than 90 RPM, not greater than 80 RPM, not greater than 70 RPM, not greater than 60 RPM, not greater than 50 RPM, not greater than 40 RPM, not greater than 35 RPM, not greater than 30 RPM, not greater than 25 RPM, or even not greater than 20 RPM. Additionally, the 362 deployable or extensible advanced edge can be fully deployed at any rotational speed between 1 RPM and 100 RPM, such as 35 RPM.
[175] When deployed, the extendable or deployable leading edge 362 may move relative to the remainder of the blade 306. In certain embodiments, the extendable leading edge 362 may translate away from the remainder of the blade 306 in a direction perpendicular to the larger surface. arcuate 352. Extendable leading edge 362 is translational along the axis of rotation of the fluid stirring element. In that regard, the aggregate width of the blade, WB, may increase after deployment of the extendable leading edge 362 as seen from a view perpendicular to the larger arcuate surface 352. In one respect, as the width of the blade, WB, increases , the surface contact between the paddle 306 and the fluid may increase. This increased surface contact can affect a higher fluidic suspension and mixing characteristic at a reduced rotational speed.
[176] During deployment of the blades 306, translation of the extendable leading edge 362 may generate or increase in size an opening 364 on the major surfaces 352 and 360 of the paddle 306 at a location adjacent to the leading edge 364. In a specific aspect, this opening 364 can increase fluid circulation and flow in vessel 340 by diverting at least some of the fluid from a coplanar path around major surfaces 352 and 360 to a transection path between major surfaces 352 and 360. In other words, fluid can be deflected through the thickness of the blades 306 so that a turbulent fluid pattern can be generated in vessel 340. It should be understood that turbulent fluid patterns can enhance suspension characteristics of fluid flow while simultaneously affecting a more homogeneous mixing action and complete.
[177] Or In addition, the addition or increase in size of the openings 364 in the blade 306 may serve to break up or eliminate fluidic dead spots or inefficiencies typically associated with relative planar motion of an object in a fluid.
[178] With further reference to Figures 36 and 37, the blade 306 may additionally include an extendable or deployable trailing edge 366. The extendable or deployable trailing edge 366 may deploy during rotation when a sufficient amount of force is applied by the fluid to extend the trailing edge 366.
[179] In specific embodiments, the deployable or extendable trailing edge 366 can begin to deploy at a rotational speed of less than 1 RPM. In other embodiments, the 366 extendable or deployable trailing edge can start to deploy at 1 RPM, 5 RPM, or even 10 RPM.
[180] In certain embodiments, the deployable or extendable trailing edge 366 may be fully deployed, or fully extended, at a rotational speed not greater than 100 RPM, such as not greater than 90 RPM, not greater than 80 RPM, not greater than 70 RPM, not greater than 60 RPM, not greater than 50 RPM, not greater than 40 RPM, not greater than 35 RPM, not greater than 30 RPM, not greater than 25 RPM, or even not greater than 20 RPM. In addition, the 366 extendable or deployable trailing edge can be fully deployed at any rotational speed between 1 RPM and 100 RPM, such as 35 RPM.
[181] When deployed, the extendable or deployable trailing edge 366 can move relative to the rest of the blade 306. Similar to the extendable leading edge 362 discussed above, in specific embodiments, the extendable trailing edge 366 can translate away from the rest of the blade. 306 in a direction perpendicular to the major arcuate surface 352. Thus, the aggregate width of the blade, WB, may increase after deployment of the extensible leading edge 366 as seen from a view perpendicular to the major arcuate surface 352.
[182] Similar to what is disclosed above, during deployment of the blades 306, translation of the extendable trailing edge 366 can generate or increase in size an opening 368 in the major surfaces 352 and 360 of the blade 306 at a location adjacent to the trailing edge 366. In particular, that opening 368 can increase fluid circulation and flow in vessel 340 by diverting at least some of the fluid from a coplanar path around major surfaces 352 and 360 to a transection path between major surfaces 352 and 360. In other words, fluid can be deflected through the thickness of the blades 306 so that turbulent fluid patterns generate in the vessel 340. It should be understood that turbulent fluid patterns can increase the suspension characteristics of fluid flow while simultaneously affecting a more homogeneous and complete mixing action.
[183] In addition, as described above, the addition or increase in size of the openings 364 and 368 in the blade 306 can serve to break up or eliminate fluidic dead spots or inefficiencies typically associated with the relative motion of an object in a fluid.
[184] Having implantable or extendable portions of the blades can serve at least two additional purposes. The first is to facilitate the ability of the paddles to be inserted into a vessel since in a non-extended or non-implanted state, the paddles have a smaller width WB. Additionally, when deployed, the increased surface area and changes in angle of attack, AA, and angle of curvature, AC, can increase mixing efficiency, and particularly enhance the ability to deliver particulate suspension at low RPMs and simultaneously transmit a low shear force on the suspended particulate substance.
[185] Specifically, as the width and angle of curvature adjust during their rotational movement, the blades can affect improved suspension and fluid mixing properties. For example, as the width of the blades, WB, increases, the surface area contact between the blades and the fluid may increase. This in turn can reduce the necessary RPMs required to mix a fluid or generate a desirable suspension in it. Correspondingly, by reducing RPMs, the magnetic impeller can facilitate equal or even improved mixing characteristics over higher RPM sets while imparting a lower shear force to the fluid. This can allow effective mixing of delicate components, such as biological organisms or pharmaceuticals, without reducing their effectiveness.
[186] Figure 38 illustrates an alternative magnetic impeller 400 including a rotating element 402, at least one blade 404 and a cage 406.
[187] In certain embodiments, the cage 406 may be coupled to another element, such as the floor of a vessel, a base, or a mixing plate to limit or confine the rotating element 402. Embodiments according to such pre-assembly of magnetic impeller can be assembled, packaged and transported and then, at a later time, when the desired mixing action is determined, a desired paddle type can be selected and engaged with the mixing pre-assembly. The formed magnetic impeller can then be sealed, sterilized, and filled with fluid(s) to be mixed.
[188] In certain embodiments, the cage 406 may confine the rotatable element 502 to the cage 406 while at least one blade 404 is disposed outside the cage 406. In such a configuration, the rotatable element 402 and the blades 404 are in assembled form as particularly illustrated, for example, in Figure 39. In certain embodiments, each of the blades 404 (when a plurality is present) may be disposed outside the cage 406.
[189] Referring now to Fig. 40, cage 406 may have an upper surface 408, a lower surface 410, and at least one side wall 412 disposed between the upper surface 408 and the lower surface 410. The cage 406 may form any shape. desired, such as, for example, a dome shape, a box shape, or any other polygonal shape that may allow the rotary member 402 to rotate freely when engaged with a magnetic drive.
[190] In additional embodiments, cage 406 may have at least one opening 414, and preferably a plurality of openings 414, extending through side wall 412 of cage 406. In a specific embodiment, at least one opening 414 may allow communication of fluid between a first cavity 416, as defined by cage 406, and a second cavity, as defined by a vessel, and as described in more detail below.
[191] In specific embodiments, at least one side wall 412 of cage 406 may have at least one opening 414, and preferably a plurality of openings 414, extending through cage 406 which may allow fluid communication with first cavity 416. particularly illustrated in Figure 40, the plurality of openings 414 may be spaced apart. The plurality of openings 414 can take any desired shape or spacing. Indeed, a specific advantage of certain embodiments of the present disclosure is the ability to customize the pattern of openings 414 or design of the cage 406. For example, the profile of the plurality of openings 414 and the overall cage design can be customized to provide an effect. of deflector, ensuring that the fluid does not settle in the first cavity 406 or elsewhere with the second cavity defined by a vessel, as will be described in more detail below.
[192] In a specific embodiment, cage 406 may include one or more fins 418. Fins 418 may at least partially extend from side wall 412 of cage 406 toward rotatable element 402 disposed in first cavity 416. Fins 418 can increase breakage and mixing of fluids including solid material or particulate matter. The fins 418 may extend towards the rotatable element 402, however the edge of the fins 418 must still be separated from the rotatable element 402 to allow the rotatable element 402 to rotate freely.
[193] In specific embodiments, at least one of the plurality of openings 414 can extend through a substantial portion or even essentially the entire height CH of the cage 406. The height CH is defined by the distance between the top surface 408 and the bottom surface 410 from cage 406.
[194] In specific embodiments, as illustrated in Figure 40, cage 406 may include a profile having at least one arcuate surface 420 forming an outer surface of cage 406. Further, in specific embodiments, cage 406 may include a profile which includes at least two arcuate surfaces 406 forming an outer surface of the cage 406.
[195] With particular reference to Figures 42 and 43, cage 406 may include a central opening 422 disposed around a desired or predetermined ideal axis of rotation AR of rotary element 402. An upright 424 on rotary element 402 may extend through the central opening 422 of cage 406. The profile of central opening 422 can determine the maximum translational movement of the rotary element, particularly the upright 424, in a direction perpendicular to the axis of rotation AR. therefore, cage 406 may be adapted to provide maximum translational movement of rotary member 402 in a direction perpendicular to an axis of rotation AR through central opening 422. In certain embodiments, central opening 422 may have a different shape than than the other openings in the plurality of openings 414, such as the opening disposed in at least one side wall 412 of the cage 406 described above. In specific embodiments, the central opening 422 may have a generally annular or circular profile. In additional embodiments, the opening 414 disposed in at least one side wall 412 of the cage 406 may be polygonal.
[196] As particularly illustrated in Figure 43, which shows a top view of a cage 406, the central opening 422 of the cage 50 may have a diameter COD. Also, as illustrated in Fig. 51, the rotatable element 402 may have a diameter HD. in certain embodiments, the diameter of the rotating element, HD, may be greater than the diameter of the central aperture COD. thus, the rotatable element 402 cannot be removed in its operating orientation through the central opening 422 of the cage 406 after the cage 406 is connected to a vessel, base, or mixing plate. In a more specific embodiment, the rotating element 402 may be sized so that it cannot be removed through the central opening 422 of the cage 406 even when reoriented from its operating orientation.
[197] Referring again to Figures 38 to 43, in specific embodiments the cage 406 may further include a flange 426 which may be disposed adjacent the side wall 412 of the cage 406 at a location opposite the top surface 408. The flange 426 may extend from side wall 412 and form a mounting surface. For example, flange 426 can be adapted to be connected to the floor of a vessel, a base or a mixing plate, as described in more detail below. In specific embodiments, flange 426 may be welded to the floor of a vessel, a base, or a mixing plate. In other embodiments, flange 426 may be connected to the floor of a vessel, a base, or a mixing pan by a plug-in connection or any other suitable connection method.
[198] As illustrated in Figure 44, the flange 426 may further include a sealing portion 428 adapted to prevent unmixed fluids and powders from being trapped under the flange 426. The sealing portion 428 may include an offset from the remainder of the flange 426. cage 406. The offset may include a angled edge 430 connecting sealing portion 428 and cage 406.
[199] The cage 406 can be formed of any desired material. In specific embodiments, cage 406 may be formed of a material that does not chemically interact with the fluid being mixed. In very specific embodiments, cage 406 may be formed from a polymer material, such as high density polyethylene (HDPE).
[200] Referring now to Figures 45a and 45b, in certain embodiments, cage 406 may have a small number of side walls 412, and relatively large cavities 414. In specific embodiments, cage 406 may have no more than 6 side walls. , not more than 5 side walls, not more than 4 side walls, not more than 3 side walls, not more than 2 side walls, or even not more than 1 side wall. For example, Figure 45a illustrates an embodiment having four side walls 412, and Figure 46a illustrates an embodiment having two side walls 412.
[201] Referring now to Fig. 45c, in certain embodiments, the magnetic impeller may further include a vessel 432. The interior of vessel 432 may define a second cavity 436 which may be adapted to retain a fluid or fluids to be mixed. Furthermore, as discussed above, cage 406 may define a first cavity 416 so that first cavity 416 and second cavity 436 may be in fluid communication. For example, as discussed in more detail above, cage 406 may have at least one opening, and particularly a plurality of openings, through which fluid can flow between first cavity 416 and second cavity 436.
[202] As described above, in specific embodiments, the swivel 402 may have a mullion 424 disposed between and coupling the swivel 402 and at least one blade 404. In such embodiments, the mullion 424 may extend into the first cavity 416 and second cavity 436. In addition, mullion 424 may extend into first cavity 416 and second cavity 436 through at least one opening, and particularly through a central opening 422 disposed around the desired axis of rotation AR of rotatable element 402 .
[203] The vessel 432 may have a top surface 438, a side surface 440, and a bottom surface 442, defining a floor 444. In specific embodiments, the floor 444 may have a generally or even substantially flat surface.
[204] In certain embodiments, cage 406 may be connected to floor 444 of vessel 432. For example, as described above, cage 406 may have an upper surface 408, a lower surface 410, and a side surface 412, and the surface lower surface 410 of cage 406 may be connected to floor 444 of vessel 432. In specific embodiments, the lower surface 410 of cage 406 may be directly connected to floor 444 of vessel 432. As used herein, the phrase "connected directly to floor" is refers to any method of connection, such as soldering, as well as removable connections, such as plug-in connections, or the like. Also, the phrase "connected directly to the floor" excludes the cage 406 being directly connected to a side wall 440 of vessel 432 or a side wall of a mixing pan. As used herein, the phrase "mixing pan" includes any structure having a base and an annular sidewall attached to the base 442.
[205] Referring to Fig. 46, in specific embodiments, the magnetic impeller may include a mixing plate 446, and the mixing plate 446 may form a part of the vessel 432, or be disposed in or otherwise connected to or form an integral part of vessel 432. In specific embodiments, as illustrated in Figure 47, mixing plate 446 may form an interior surface 448 of vessel 432. In certain embodiments, mixing plate 446 may have a floor 450, and the floor 450 of mixing plate 446 can form floor 444 of vessel 432 as described above. Therefore, in such embodiments, cage 406 may be connected, or even directly connected, to floor 444 of mixing pan 446.
[206] In specific embodiments, mixing pan 446 may have at least one annular sidewall 452, which in certain embodiments, may also have greater rigidity than that of at least one flexible sidewall 440 of vessel 432. As described above , cage 406 can be connected to floor 444, and when mixing pan 446 includes an annular side wall 452, side surface 414 of cage 406 can be separated from annular side wall 452 of mixing pan 446 by a predetermined distance or desired.
[207] In other embodiments, as particularly illustrated in Figure 48, a magnetic impeller may not include a mixing pan, but may instead include a base 454. Base 454 may be exempt from an annular side wall extending at an angle. sharp around the entire outer profile of base 454. As used herein, the term "base" includes a generally flat surface that does not include a complete annular sidewall unitary with the base. The definition of the term "base" includes a structure having a partial annular sidewall unitary with the base. Further, the definition of the term "base" includes a structure having a partial or complete annular side wall forming a part of the cage when the cage 406 is connected to the base 454. The base 454 can form any desirable shape. In certain embodiments, base 454 may be circular or generally disk-shaped. In other embodiments, the base 454 can be any polygonal shape. In additional embodiments, base 454 may have a higher rigidity than at least one flexible sidewall 440 of vessel 432. Base 454 may have a generally flat outline, or in other embodiments, may be tapered toward the center.
[208] Referring to Fig. 49, in very specific embodiments, the base 454 may have a bulge 456 disposed around the desired axis of rotation AR of the swivel element 402. The bulge 456 may be in the form of a ring or have a generically annul format. The bulge 456 may act to limit the translational movement of the turning element 402 perpendicular to the desired axis of rotation AR of the turning element 402 when the turning element 402 is rotating. The bulge 456 may have a generally small height.

[234] The rigid or flexible vessel may be made of any desirable material. For example, the rigid or flexible vessel may contain a polymer, a metallic or metal material, ceramic, glass or a fibrous material. In specific embodiments, the rigid vessel may include a rigid polymeric material.
[235] Additional embodiments of the present disclosure pertain to magnetic impellers having improved mixing performance, which can be described, for example, as high suspension of particles at low RPMs. Such an improvement can be seen both in circulation and, particularly, in the ability to keep particulate substances in suspension during a mixing operation. For example, one type of particulate substance suspension is cell suspension, which is used in the pharmaceutical and biological industries. One way to describe and quantify the ability of a magnetic impeller to keep particulate matter in suspension is the Particulate Suspension Test. The Particulate Suspension Test measures the amount of particulate matter in suspension and provides results as a percentage of suspended particulate matter (ie, particulate matter suspension efficiency). The procedure for performing the Particulate Substance Suspension Test is provided in detail below in the examples.
[236] In certain embodiments, a magnetic impeller as described herein may have a particulate matter suspension efficiency of at least 50%, at least 60%, at least 70%, at least 75%, and at least 80%, at at least 85%, at least 90%, at least 95%, at least 97%; or even at least 99% as measured according to the Particulate Substance Suspension Test. Additionally, in very specific embodiments, the magnetic impeller described herein may have all particles in suspension, such as 100% particulate suspension efficiency.
[237] An additional specific advantage of certain embodiments of the present disclosure is the achievement of the aforementioned particulate suspension efficiency at low RPMs. In certain embodiments, a magnetic impeller as described herein may have the above-mentioned particulate matter suspension efficiency of not more than 30 RPMs, not more than 40 RPMs, not more than 50 RPMs, not more than 55 RPMs, not not exceeding 60 RPM, not exceeding 65 RPM, not exceeding 70 RPM, not exceeding 75 RPM, not exceeding 80 RPM, not exceeding 85 RPM, not exceeding 90 RPM, not exceeding 95 RPM, not exceeding 100 RPM, not exceeding 110 RPM, not exceeding 120 RPM, not exceeding 130 RPM, not exceeding 140 RPM, not exceeding 150 RPM, not exceeding 160 RPM, not exceeding 170 RPM, not exceeding 180 RPM , not exceeding 190 RPM, or even not exceeding 200 RPM.
[238] In very specific embodiments, the magnetic impeller described herein may have a suspension-mixing efficiency of at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95 %, at least 97%, or even at least 99% and no more than 200 RPMs.
[239] In very specific embodiments, the magnetic impeller described herein may have a suspension-mixing efficiency of at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95 %, at least 97%, or even at least 99% and no more than 150 RPMs.
[240] In very specific embodiments, the magnetic impeller described herein may have a suspension-mixing efficiency of at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at minus 95%, at least 97%, or even at least 99% and no more than 100 RPM.
[241] Similar to the advantage described above of being able to achieve improved particulate suspension efficiencies at low RPMs, a magnetic impeller described herein can also impart low shear to the medium being mixed.
[242] As used herein, “shear” is synonymous with “shear stress” and refers to a force that deforms, or causes to deform, a fluid (eg, liquid or gas). Shear stress is generally a measure of the frictional force between a fluid and a body. As should be understood, a fluid at rest cannot withstand shear stress. Conversely, when a fluid is in motion, shear stresses can develop within the fluid. In this regard, any fluid moving along a boundary will incur shear stress in a region along that boundary. Typically, if the friction force along the boundary is constant, the shear stress will be linearly dependent on the velocity gradient. However, the introduction of particles into the fluid can distort traditional shear equations. EXAMPLESExample 1 - Levitation
[243] A magnetic impeller as illustrated in Figure 1 is physically installed inside a container such that the magnetic impeller will not slide inside the container during operation. A fluid comprising purified water is introduced into the container such that the fluid completely covers the magnetic impeller. A drive magnet is positioned concomitantly with the magnetic member of the magnetic impeller such that a magnetic coupling is formed therebetween. A quarter of a cup of sea salt is introduced into the fluid inside the vessel and the trigger magnet is turned on.
[244] The drive magnet is rotated, causing the magnetic impeller to rotate. The fluid stirring element begins to aerodynamically levitate and translate along the column from a rotation of approximately 65 revolutions per minute. Example 2 - Suspension of Particulate Substance
[245] A magnetic impeller, as illustrated in Figure 1, with the blades as illustrated in Figures 19-20 was constructed and tested for its ability to suspend particulate materials at various rotational speeds. A cylindrical container was filled with 100 L of water. 1000 spherical polymer beads having a specific gravity of 1.2 and a method diameter of 2 cm were added to the water. A magnetic trigger was positioned under the vessel and activated. The container was visually observed with a GoPro® camera and the number of suspended and suspended pellets was counted. A pellet was considered out of suspension if it did not rise above the plane of the blades after an interval of 10 seconds. Similarly, a pellet was considered to be in suspension if the pellet rose above the plane of the blades within a 10 second interval. The particulate matter suspension efficiency was then calculated as a percentage of the total number of beads in suspension divided by the total number of beads.
[246] Additionally, the amount of shear imparted to the fluid by the magnetic impeller was determined. The following results were obtained.Table 1: Particulate Substance Suspension Test Results
