    BACKGROUND Field of Revelation
    [001] The present disclosure is generally directed to various methods and devices that can be used for vibratory separation of materials and, in particular, to various screens for vibratory separation devices that can be configured to increase and / or maximize the effect of forces generated by vibratory separation devices. DESCRIPTION OF RELATED TECHNIQUE
    [002] Vibratory separation devices are used in a wide variety of industries to separate materials such as liquids from solids or solids from liquids. A type of vibratory separation device that is often used to separate materials during well drilling operations, such as oil and gas drilling operations and the like, is known as a vibrating screen (vibrating screen). On many drilling platforms, a vibrating screen is typically the first component of equipment used to treat mixtures of drilling fluid that resume from the well bore and is used to remove unwanted solid materials, such as drill cuttings, from the fluid, that is, drilling mud, which is used to drill the well.
    [003] In general, a vibrating screen includes a box-type frame, called a basket, which receives the material to be separated, for example, a mixture of drill cuttings and drilling mud or fluid. A deck, or other screen mounting or containment structure, is supported within the basket and includes one or more sections of screen that remove solid particles from the fluid as the fluid passes through the screen. A vibrating device is attached to the vibrating screen to vibrate the screens to improve the separation process.
    [004] In operation, the mixture of drill cuttings and drilling fluid is fed into the vibrating screen at the top of the screen sections, and particles that are larger than the openings in the screen section are captured on top of the screen. The vibrating screen is configured to vibrate the screen in such a way that particles trapped by the screen are moved along and, eventually, out of the screen section. Therefore, the screen sections need to be configured to process a high volume of fluid, separate particles of various different sizes from the fluid and withstand the high forces that are generated by the vibration of the vibrating screen and the movement of the cuttings and drilling fluid. .
    [005] Consequently, there is a need for continuity in the technique by the development of new methods and separation devices that can provide sections of screen that mitigate, or even resolve, these and other limitations of existing separation equipment and methods. DESCRIPTION SUMMARY

    [028] Although the material disclosed in the present disclosure is susceptible to several modifications and alternative forms, the specific illustrative modalities of the same have been shown by way of example in the drawings and will be described in detail below. It should be understood, however, that the description in the present invention of specific modalities is not intended to limit the invention to the revealed particular forms, but, on the contrary, the intention is to cover all modifications, equivalents and alternatives that fit the spirit and scope of the present disclosure as defined by the appended claims. DETAILED DESCRIPTION
    [029] Several illustrative modalities of the present matter are described below. For clarity, not all the features of an actual deployment are described in this specification. It will, of course, be evident that in the development of any such real modality, a number of specific implementation decisions must be made to achieve the specific objectives of the developers, such as compliance with system-related and business-related constraints, which will vary from one deployment to another. Furthermore, it will be evident that such a development effort can be complex and time-consuming, however, it will nevertheless be adapted to the routine for the elements of common skill in the technique that have the benefit of this revelation.
    [030] The present matter will now be described with reference to the attached Figures. Various systems, structures and devices are schematically revealed in the drawings for purposes of explanation only and in order not to obscure the present disclosure with details that are well known to those skilled in the art. However, the accompanying drawings are included to describe and explain the illustrative examples of the present disclosure. The words and phrases used in the present invention must be understood and interpreted as having a meaning consistent with the understanding of those words and phrases by those versed in the relevant technique. No special definition of a term or phrase, that is, a definition that is different from the common and usual meaning as understood by those skilled in the art, is intended to be implied by consistent use of the term or phrase in the present invention. To the extent that a term or phrase is intended to have a special meaning, that is, a meaning different from that understood by versed elements, such a special definition will be expressly presented in the specification by definition which directly or unequivocally provides the special definition for the term or phrase. .
    [031] Referring initially to the schematically illustrated screen panel revealed in the planar and isometric views of Figures 1A and 1B, respectively, a screen panel 100 is shown as a substantially flat body that is substantially aligned with a plane 111. Typically, the screen panel 100 may include one or more layers of tiling material (not shown for clarity), for example, wire mesh screen, which is arranged along an upper surface of screen panel 100. In operation, the panel screen 100 can be subjected to vibrational acceleration along a displacement vector 112a which can be at an angle 114a to a vector 116a which is substantially perpendicular to plane 111 of screen panel 100. Additionally, a mixture of material , for example, a mixture of drilling fluid and drill cuttings, can be directed over the screen panel 100 in a flow direction 118 which is substantially parallel to a ge axis longitudinal ometric 101 of the screen panel 100. As the material mixture moves along the screen panel 100 in the direction 118, the vibration of the screen panel 100 can accelerate the material mixture along the displacement vector 112a. This vibrational acceleration results in a force acting to push at least a portion of the fluid through openings in the tiling material in the screen panel 100, while the screen material can act to prevent solid particles larger than the openings in the screen material. through the screen panel 100.
    [032] Generally, the angle 114a of the displacement vector 112a relative to the vector 116a (which can be substantially perpendicular to the plane 111 of the screen panel 100) may be dependent on the design parameters of the specific vibratory separation device, such as a screen vibratory and the like, on which screen panel 100 can be installed. For example, in certain illustrative embodiments, the angle 114a of displacement vector 112a can be between approximately 35 ° and 55 ° with respect to vector 116a. It should be appreciated, however, that the angle 114a of the displacement vector 112a may be less than approximately 35 ° or greater than approximately 55 °, depending on the design of the vibrating separation device on which the screen panel 100 is installed.
    [033] As is shown schematically in Figures 1A and 1B, the screen panel 100 may include a raised screen component 120 that has an inclined front surface 122. In some illustrative embodiments, the raised screen component may be at least partially constructed from tiling material that is adapted to allow the fluid to pass through it, as described above. For example, at least the inclined front surface 122 of the raised screen member may include tiling material (not shown) disposed thereon. In addition, in certain embodiments, the inclined screen surface 122 may be inclined with respect to the plane 111 of the screen panel so that the inclined screen surface 122 is aligned with a plane that is substantially perpendicular to a vibrational acceleration displacement vector. 112b. As described in relation to the displacement vector 112a above, the displacement vector 112b can be at an angle 114b with respect to a vector 116b which is also substantially perpendicular to the plane 111 of the screen panel 100. Therefore, it must be appreciated by those elements of common knowledge in the art after a complete reading of the present disclosure that the displacement vector 112b can be substantially parallel to the displacement vector 112a.
    [034] In certain exemplary embodiments, the orientation of the tilted screen surface 122 so that it is aligned with a plane that is substantially perpendicular to the displacement vector 112b can act to effectively increase the total screen area that is available to process the fluid mixture. Additionally, in these illustrative embodiments in which multiple layers of tiling material can be arranged on the inclined screen surface 122, alignment of the inclined screen surface 122 as described above can also reduce the amount of friction wear between multiple layers of tiling material, as can be caused by the various layers of tiling material that move relative to each other during operation. In addition, alignment of the inclined screen surface 122 in this way can also increase the effective capacity of the screen panel 100 compared to a conventional flat panel, i.e., a screen panel without elevated screen components 120.
    [035] As noted earlier, the inclined screen surface 122 can be aligned with a plane that is substantially perpendicular to the displacement vector 112b, which in turn is generally substantially parallel to the longitudinal geometric axis 101 of the screen panel 100. As shown in Figures 1A and 1B, lines 108 indicate the direction of a plane that is arranged exactly perpendicular to the longitudinal geometric axis 101, and to the displacement vectors 112a and 112b. However, for purposes of the present disclosure, the term "substantially perpendicular" when used in relation to the orientation of the inclined screen surface 122b with respect to the longitudinal geometric axis 101 is intended to mean an orientation that is close to, but not exactly, perpendicular to the geometric axis longitudinal 101, as is the case with plans that include lines 108.
    [036] For example, in some exemplifying embodiments, the inclined screen surface 122 may be aligned with a plane that includes line 128, which may be at an angle 126 to perpendicular line 108. In such modalities, the vector of offset 112b can be rotated about a geometrical axis 124 which is contained within the plane of the inclined screen surface 122, in which, however, displacement vector 112b remains perpendicular to geometry axis 124. Therefore, according to with the present disclosure, displacement vector 112b is considered to be "substantially perpendicular" to a plane that is aligned with the inclined screen surface 122 and includes line 128, which may be at 126 relative to perpendicular line 108.
    [037] Therefore, in certain embodiments, the inclined screen surface 122 can be considered to be aligned with a plane that is "substantially perpendicular" to the displacement vector 112b when the inclined screen surface 122 is aligned with a plane that is oriented at an angle 126 to the perpendicular line 108 which is less than approximately 45 °. In other embodiments, the inclined screen surface 122 can be considered to be aligned with a plane that is "substantially perpendicular" to the displacement vector 112b when the inclined screen surface 122 is aligned with a plane that is oriented at an angle 126 that is less than approximately 22.5 °. In still other embodiments, the inclined screen surface 122 can be considered to be aligned with a plane that is "substantially perpendicular" to the displacement vector 112b when the inclined screen surface 122 is aligned with a plane that is oriented in a plane. angle 126 which is less than approximately 10 °.
    [038] Figure 2A is a perspective view of an exemplary screen panel assembly 200 in accordance with the present disclosure, and Figure 2B is a perspective view of an elevated screen component 220 illustrative of the panel assembly. 200 shown in Figure 2A. In some embodiments, the screen panel assembly 200 may include a plurality of individual screen panels 202, each of which may include an elevated screen component 220, as will be described in more detail with reference to Figure 2B below. In other embodiments, each screen panel 202 may include a plurality of elevated screen components 220, for example, two or more, coupled thereto, while, in still other embodiments, the screen panel assembly 200 may include a single substantially continuous screen panel 202. In those embodiments where the screen panel assembly 200 includes a single substantially continuous screen panel 202, each of the plurality of elevated screen components 202 may be coupled to the screen panel assembly 200, for example, to screen panel 202.
    [039] As shown in Figure 2A, the elevated screen components 220 can have one or more inclined front screen surfaces 222, each of which can be arranged substantially perpendicular to a vibrational acceleration displacement vector 212 which is based on the operational characteristics of the vibrating separation device, for example, a vibrating screen (not shown), on which the screen panel assembly 200 can be installed. As shown in Figure 2A, the plurality of raised screen components 220 can be arranged by mounting the screen panel 200 in a staggered or offset pattern, so that the centerline of a given raised screen component 220 in a row of raised screen components 220 can be substantially aligned with a flow span 215 between immediately adjacent pairs of raised screen components 220 in an upstream and downstream row of raised screen components 220. See Figure 2C.
    [040] In some embodiments, a mixture of material, for example, drilling fluid and drill cuttings, can generally flow through the screen panel assembly 200 in a nominal material flow direction 218 that is substantially parallel to the geometric axis longitudinal 201 of the screen panel assembly 200. However, in view of the staggered or displaced pattern arrangement of the elevated screen components 220, the material mixture may have a serpentine or locally indirect flow path 217, that is, where the material flows around each of the raised screen components 220, through the flow spans 215 between each raised screen component 220, and then to the next row of raised screen components 220. See Figures 1 and 2C.
    [041] As noted earlier, in at least some embodiments, screen panel 202 may include a single elevated screen panel component 220 (as shown in the illustrative embodiment shown in Figure 2B), while in other embodiments, the screen panel 202 may include a plurality of raised screen panel components 220. If the screen panel 202 includes a single raised screen panel component 220 (as shown in Figure 2B) or a plurality of raised screen panel components 220, each of the elevated screen panel assemblies may include one or more angled front-side screen surfaces 222, side panels 213, a wedge surface, or ditch, 210, and one or more vertical rear-side screen surfaces 206. The raised screen panel assembly 220 may include a frame 203 which is adapted to support the inclined screen surfaces 222, the vertical screen surfaces 206 and the side panels 21 3. As shown in Figure 2B, frame 203 may include a first edge or bottom edge 207 that runs along the bottom edge of the sloped screen surfaces 222 that can be aligned with the top surface of the screen panel 202. Additionally, the frame 203 can also include second edges or side edges 209 extending upwardly from the top surface of the screen panel 202 to a third edge or top edge 211, thereby forming a substantially triangular shaped frame which has a height of 203h when viewed in cross section or from the side.
    [042] The height 203h of the frame 202 can be established based on the design parameters of the vibrating separator, for example, vibrating screen, where in the screen panel assembly 200 it can be installed, such as the material flow rate through the assembly screen panel 200, the anticipated depth of the material group in the screen panel assembly 200, the upward angle at which the screen panel assembly 200 can be vibrated and the like. For example, in certain exemplifying modalities, the height 203h can be in the range of approximately 2.5 centimeters (1 inch) to 7.6 centimeters (3 inches), while in at least some modalities the height can be approximately 5.1 centimeters (2 inches). However, it should be appreciated that other heights 203h of the raised screen components 220 can also be used. In addition, it should also be understood that the height 203h of each of the raised screen components 220 may be different for each of the various screen panels 202 of the screen panel assembly 200 and / or the height 203h of the various raised screen components 220 on a given screen panel 202 may be different.
    [043] In certain embodiments, frame 203 may include one or more inclined screen panel frame members 222f that are positioned between and adapted to support each of the inclined screen surfaces 222. In other embodiments, frame 203 may include one or more vertical screen panel frame members 206f which are also positioned between and adapted to support each of the vertical screen surfaces 206. Additionally, the screen panel 202 may include tiling material 221 disposed on the upper surface thereof as well as a plurality of screen panel frame members 202f that are adapted to support the tiling material 221.
    [044] As shown in Figure 2B, the inclined screen surfaces 222 can be inclined with respect to the screen panel 202, that is, perpendicular to the displacement vector 212 and, additionally, can be aligned with a plane that is oriented in a angle 226 with respect to a plane that is perpendicular to the longitudinal geometric axis 201 and the displacement vector 212, for example, the front edge 202e of the panel 202, as previously described. In some illustrative modes, the angle 226 may be less than approximately 45 ° and, in certain other modalities, the angle 226 may be less than approximately 22.5 °. In addition, one or both of the side panels 213 and / or the wedge surface 210 may be a mesh surface, for example, the tiling material, whereas, in other embodiments, the side panels 213 and / or the surface of cu -line 210 can be solid surfaces, for example, foil and the like. In other embodiments, the frame assembly 203 can be arranged so that the inclined web surfaces 222 form a shallow-side or “V” shaped configuration, where the wedge surface 110 can be positioned at the intersection of surfaces vertical screens.
    [045] As noted earlier, each of the elevated screen components 220 can be arranged in a staggered or offset pattern in the screen panel assembly 200. As shown in Figure 2C, which is a plan view of the screen panel assembly 200 shown in Figure 2A, the center line of each raised screen component 200, that is, the wedge surface 210 of each respective frame 203 (see Figure 2B), can be aligned with the flow gap 215 between the frames 203 of an adjacent pair of raised screen components 220 which are immediately upstream thereof. In the illustrative embodiment of Figure 2C, each flow span 215 can be scaled in relation to the adjacent flow spans 215 so that the wedge surfaces 210 of each respective frame 203 act to change the flow path of the material mixture over the assembly screen panel 200 and thereby form a serpentine or indirect flow path 217 that generally moves along the material flow direction 218. It should be understood that, in light of the general operating characteristics of typical vibratory separation, for example, vibrating screens, the solid particles that are separated by the screen assembly 200 will typically tend to move along the serpentine flow path 217 as the screen panel assembly 200 is vibrated along the vector of offset 212 during operation.
    [046] Figure 2D is a plan view approaching the illustrative screen panel 202 and the raised screen component 220 shown in Figure 2B and described above. Additionally, Figure 2E is a front elevation view of screen panel 202 when viewed along the line of sight “2E-2E” of Figure 2D, and Figure 2F is a side elevation view of screen panel 202 when viewed along the “2F-2F" line of sight. As shown in Figure 2D, the front edge 202e can be perpendicular to the longitudinal geometric axis 201 (and, that is, the offset vector 212), and the sloped screen surfaces 222 they can be oriented at an angle 226 to the front edge 202e (that is, to a plane that is perpendicular to the displacement vector 212), and partial flow spans 215 are positioned adjacent to each side panel 213. As shown in Figures 2D at 2F, the wedge surface 210 can typically be positioned substantially on the centerline of frame 203, that is, between each side of the raised insignia-shaped screen component 220. As shown in Figure 2F, frame 203 can be of a height 203h, and side panels 213 may have a substantially triangular shape.
    [047] In certain exemplary embodiments, the frame 203 of each raised screen component 220 can be constructed as an integral component of an individual screen panel 202. In other embodiments, the frames 203 can be separately constructed and coupled to the panel assembly 200 fabric by adhesives, cold welding, welding or other coupling methods. Additionally, in at least some embodiments, the frames 203 for individual raised screen components 220 can be removably attached to the screen panel 202, thereby facilitating the removal of frames 203 from the screen panel assembly 200 for replacement or repair as needed regardless of other raised screen components, ie without replacing the entire screen panel assembly 200.
    [048] In operation, the screen panel assembly 200 can be displaced, or vibrated, along displacement vector 212 while a mixture of fluid, for example, a mixture of drilling fluid and drill cuttings, is fed through of the screen panel assembly 200 in the direction of material flow 218. As the material mixture moves along the screen panel assembly 200, at least some of the fluids that make up the material mixture may pass through the surfaces of the screen 221 of the screen panels 202, the vertical screen surfaces 206 and the angled screen surfaces 222. Solid particles of the mixture that cannot pass through the surfaces of the screen 221, the vertical screen surfaces 206 or the inclined screen surfaces 222 may tend to rest on the surfaces 221 of the screen panels 202. The combination of material flow in the general direction 218 and the acceleration or vibrational displacement of the screen panel assembly 200 along the The displacement vector can therefore cause the solid particles to move continuously through the screen panel assembly 200 along the serpentine flow path 217 (see Figures 2B and 2C).
    [049] Figure 3A is a perspective view of an additional illustrative screen panel assembly 300 of the present invention, and Figure 3B is an approximate perspective view of an elevated screen component 320 exemplifying the screen panel assembly. 300 shown in Figure 3A. Similar to the screen panel assembly 200 illustrated in Figures 2A to 2F above, the screen panel assembly 300 may include a plurality of individual screen panels 302, each of which may include an elevated screen component 320. See , for example, Figure 3B, described in further detail below. In other embodiments, each screen panel 302 may include a plurality of raised screen components 320, for example, two or more, coupled thereto, while, in yet other embodiments, the screen panel assembly 300 may include a single substantially continuous screen panel 302. In those embodiments where the screen panel assembly 300 includes a single substantially continuous screen panel 302, each of the plurality of raised screen components 320 can be coupled to the screen panel assembly 300, for example, to screen panel 302.
    [050] As shown in Figure 3A, the elevated screen components 320 can have an inclined front screen surface 322, which can be arranged substantially perpendicular to a vibrational acceleration displacement vector 312 which is based on the operational characteristics of the device. vibrating separator, for example, vibrating screen (not shown), on which the screen panel assembly 300 can be installed. As shown in Figure 3A, the plurality of raised screen components 320 can be arranged by mounting the screen panel 300 in a staggered or offset pattern, so that the centerline of a given raised screen component 320 in a row of raised screen components 320 can be substantially aligned with a flow span 315 between immediately adjacent pairs of raised screen components 320 in an upstream and downstream row of raised screen components 320. See Figure 3c.
    [051] In some embodiments, a mixture of material, for example, drilling fluid and drill cuttings, can generally flow through the screen panel assembly 300 in a nominal material flow direction 318 that is substantially parallel to the geometric axis longitudinal 301 of the screen panel assembly 300. However, in view of the staggered or displaced pattern arrangement of the raised screen components 320, the material mix may have a serpentine or locally indirect flow path 317, that is, where material flows around each of the raised screen components 320, through the flow spans 315 between each raised screen component 320, and then to the next row of raised screen components 320. See Figures 3B and 3C.
    [052] As noted earlier, in at least some embodiments, screen panel 302 may include a single raised screen panel component 320 (as shown in the illustrative embodiment shown in Figure 3B), while in other embodiments, screen panel 302 can include a plurality of raised screen panel components 320. If screen panel 302 includes a single raised screen panel component 320 (as shown in Figure 3B) or a plurality of raised screen panel components 320, when the screen panel includes a single elevated screen panel assembly 320, each of the elevated screen panel assemblies can include an inclined front-side screen surface 322, side panels 313, a wedge surface, or ditch , 310, and rear rear vertical screen surfaces 306. The raised screen panel assembly 320 may include a frame 303 which is adapted to support the inclined screen surface 322, its surfaces and vertical screen profiles 306 and side panels 313.
    [053] As shown in Figure 3B, frame 303 can include a first edge or bottom edge 307 that runs along the bottom edge of the sloped screen surface 322 that can be aligned with the top surface of the screen panel 302. Additionally , frame 303 may also include second edges or side edges 309 extending upwardly from the top surface of the screen panel 302 to a third edge or top edge 311. In some embodiments, the third edges 311 are arranged in a internal angle to a center line of the frame 303 and upwards to an upper point 303u at a height 303h above the screen panel 302, so that the inclined screen surface 322 forms a modified pentagon shape. As noted with respect to raised screen components 220 in Figures 2A to 2F above, the height 303h of raised screen components 320 can be in the range of approximately 2.5 centimeters to 7.6 centimeters (1 inch to 3 inches), although other heights can also be used depending on the design parameter of the vibrating separation device.
    [054] In some embodiments, frame 304 may extend downward from the top point 303u to the top surface of the screen panel 302 to form the wedge surface 310. Additionally, the screen panel 302 may include tiling material 321 disposed on the upper surface of the same. In some embodiments, one or both of the side panels 313 and / or the wedge surface 310 may be a mesh surface, for example, the tiling material, while in other embodiments, the side panels 313 and / or the surface wedge 310 can be solid surfaces, for example, foil and the like.
    [055] In some embodiments, the angled screen surface 322 can be angled with respect to the screen panel 302 at an angle that is perpendicular to the offset vector 312. Additionally, although Figure 3B shows that the angled screen surface 322 can be aligned with a plane that includes the front edge 302e of the screen panel 302, and that the front edge 302e can be oriented at an angle 326 that is perpendicular to the longitudinal geometric axis 301, it should be appreciated that the front edge 302e of the screen panel screen 302 - and the plane of the inclined screen surface 322 - need not be perpendicular to the longitudinal geometry axis 301. Instead, as with the illustrative screen panel 202 shown in Figures 2B to 2F above, the inclined screen surface 322 can be aligned with a plane that is oriented at an angle to a plane that is perpendicular to the longitudinal axis 301 and to the displacement vector 312, in which in some modalities the angle is less than approximately 45 °.
    [056] As noted earlier, each of the raised screen components 320 can be arranged in a staggered or offset pattern in the screen panel assembly 300. As shown in Figure 3C, which is a plan view of the screen panel assembly 300 shown in Figure 3A, the center line of each raised screen component 300, that is, the wedge surface 310 of each respective frame 303 (see Figure 3B), can be aligned with the flow gap 315 between the frames 303 of an adjacent pair of raised screen components 320 which are immediately upstream thereof. In the illustrative embodiment of Figure 3C, each flow span 315 can be scaled in relation to the adjacent flow spans 315 so that the wedge surfaces 310 of each respective frame 303 act to change the flow path of the material mixture over the assembly screen panel 300 and thereby form a serpentine or indirect flow path 317 that generally moves along the material flow direction 318. It should be understood that, in light of the general operating characteristics of typical vibratory separation, for example, vibrating screens, the solid particles that are separated by the screen assembly 300 will typically tend to move along the serpentine flow path 317 as the screen panel assembly 300 is vibrated along the vector of offset 312 during operation.
    [057] Figure 3D is a plan view approaching the illustrative screen panel 302 and the raised screen component 320 shown in Figure 3B and described above. Additionally, Figure 3E is a front elevation view of screen panel 302 when viewed along the line of sight “3E-3E” of Figure 3D, and Figure 3F is a side elevation view of screen panel 302 when viewed along the “3F-3F" line of sight. As shown in Figure 3D, the front edge 302e can be perpendicular to the longitudinal geometric axis 301 (and, that is, the offset vector 312), in this case, the screen surface angled 322 will be aligned with a plane that is oriented at an angle 326 that is perpendicular to the offset vector 312. However, as noted above, the front edge 302e of the screen panel 302 - and the plane of the inclined screen surface 322 - will not it needs to be perpendicular to the longitudinal geometric axis 301. Therefore, in at least some embodiments, the inclined screen surface 322 can be aligned with a plane that is oriented at an angle to a plane that is perpendicular to the longitudinal axis 301 and at the time displacement torus 312, in which in some embodiments the angle is less than approximately 45 °.
    [058] Also as shown in Figure 3D, the partial flow spans 315 are positioned adjacent to each side panel 313 of the raised screen component 320. Additionally, as shown in Figures 3D to 3F, the wedge surface 310 can typically be positioned substantially along the center line of the frame 303, where the frame 303 can have a height 303h, the side panels 313 can have a substantially triangular shape and the rear side screen surfaces 306 can have a substantially trapezoidal shape.
    [059] In certain exemplary embodiments, the frame 303 of each raised screen component 320 can be constructed as an integral component of an individual screen panel 302. In other embodiments, the frames 303 can be separately constructed and coupled to the panel assembly of screen 300 by adhesives, cold welding, welding or other coupling methods. Additionally, in at least some embodiments, the frames 303 for individual raised screen components 320 can be removably attached to the screen panel 302, thereby facilitating the removal of frames 303 from the screen panel assembly 300 for replacement or repair as needed regardless of other elevated screen components, ie without replacing the entire 300 screen panel assembly.
    [060] In operation, the screen panel assembly 300 can be displaced, or vibrationally accelerated, along displacement vector 312 while a mixture of fluid, for example, a mixture of drilling fluid and drill cuttings, is fed through the screen panel assembly 300 in the direction of material flow 318. As the material mixture moves along the screen panel assembly 300, at least some of the fluids that make up the material mixture may pass through the surfaces of the screen 321 of the screen panels 302, the vertical screen surfaces 306 and the angled screen surfaces 322. Solid particles of the mixture that cannot pass through the surfaces of the screen 321, the vertical screen surfaces 306 or the inclined screen surfaces 322 can tend to rest on the surfaces 321 of the screen panels 302. The combination of material flow in the general direction 318 and the vibrational acceleration or displacement of the panel assembly t it 300 along the displacement vector can thus cause the solid particles to move continuously through the screen panel assembly 300 along serpentine flow path 317 (see Figures 3B and 3C).
    [061] Figure 4A is a perspective view of an additional illustrative screen panel assembly 400 of the present invention, and Figure 4B is an approximate perspective view of an elevated screen component 420 exemplifying the screen panel assembly. 400 shown in Figure 4A. Similar to the screen panel assembly 200 illustrated in Figures 2A to 2F above, the screen panel assembly 400 may include a plurality of individual screen panels 402, each of which may include an elevated screen component 420. See , for example, Figure 4B, described in further detail below. In other embodiments, each screen panel 402 may include a plurality of raised screen components 420, for example, two or more, coupled thereto, while, in yet other embodiments, the screen panel assembly 400 may include a single substantially continuous screen panel 402. In those embodiments where the screen panel assembly 400 includes a single substantially continuous screen panel 402, each of the plurality of raised screen components 420 can be coupled to the screen panel assembly 400, for example, to screen panel 402.
    [062] As shown in Figure 4A, the raised screen components 420 may have an inclined front screen surface 422, which can be arranged substantially perpendicular to a vibrational acceleration displacement vector 412 which is based on the operational characteristics of the device. vibrating separator, for example, vibrating screen (not shown), on which screen panel assembly 400 can be installed. As shown in Figure 4A, the plurality of raised screen components 420 can be arranged by mounting the screen panel 400 in a staggered or offset pattern, so that the centerline of a given raised screen component 420 in a row of raised screen components 420 can be substantially aligned with a flow span 415 between immediately adjacent pairs of raised screen components 420 in an upstream and downstream row of raised screen components 420. See Figure 4C.
    [063] In some embodiments, a mixture of material, for example, drilling fluid and drill cuttings, can generally flow through the screen panel assembly 400 in a nominal material flow direction 418 that is substantially parallel to the geometric axis longitudinal 401 of the screen panel assembly 400. However, in view of the staggered or displaced pattern arrangement of the elevated screen components 420, the material mixture may have a serpentine or locally indirect flow path 417, that is, in which material flows around each of the raised screen components 420, through the flow spans 415 between each raised screen component 420, and then to the next row of raised screen components 420. See Figures 4B and 4C .
    [064] As noted earlier, in at least some embodiments, screen panel 402 may include a single raised screen panel component 420 (as shown in the illustrative embodiment shown in Figure 4B), while in other embodiments, screen panel 402 can include a plurality of raised screen panel components 420. If the screen panel 402 includes a single raised screen panel component 420 (as shown in Figure 4B) or a plurality of raised panel components raised screen 420, each of the raised screen panel assemblies may include a slanted front side screen surface 422, side panels 406 and a wedge surface, or ditch, 410. The raised screen panel assembly 420 may include a frame 403 which is adapted to support the inclined screen surface 422 and side panels 406.
    [065] As shown in Figure 4B, frame 403 may include a first edge or bottom edge 407 that runs along the bottom edge of the sloped screen surface 422 that can be aligned with the top surface of the screen panel 402. Additionally the frame 403 may also include second edges or top edges 409 which are arranged at an inward angle to a center line of the frame 403 and upward to an upper point 403u at a height 403h above the screen panel 402, so that the inclined screen surface 422 forms a triangular shape. As noted with respect to the raised screen components 220 in Figures 2A to 2F above, the height 403h of the raised screen components 420 can be in the range of approximately 2.5 centimeters to 7.6 centimeters (1 inch to 3 inches), although other heights can also be used depending on the design parameter of the vibrating separation device.
    [066] In some embodiments, the frame 404 may extend downward from the upper point 403u to the upper surface of the screen panel 402 to form the wedge surface 410. In some embodiments, the side panels 406 may be solid surfaces , for example, foil and the like. In other embodiments, one or both side panels 406 may be a screen surface, for example, tiling material, in which case the wedge surface 410 may also include an extended wear plate 410w in order to reduce wear as the material mixture flows around the wedge surface along the serpentine path 417. In addition, the screen panel 402 can include tiling material 421 disposed on the upper surface thereof.
    [067] In some embodiments, the tilted screen surface 422 can be tilted relative to the screen panel 402 at an angle that is perpendicular to the offset vector 412. Additionally, although Figure 4B shows that the tilted screen surface 422 can be aligned with a plane that includes the front edge 402e of the screen panel 402, and that the front edge 402e can be oriented at an angle 426 that is perpendicular to the longitudinal geometric axis 401, it should be appreciated that the front edge 402e of the screen panel screen 402 - and the plane of the inclined screen surface 422 - need not be perpendicular to the longitudinal geometric axis 401. Instead, as with the illustrative screen panel 202 shown in Figures 2B to 2F above, the inclined screen surface 422 can be aligned with a plane that is oriented at an angle to a plane that is perpendicular to the longitudinal axis 401 and the displacement vector 412, in which in some modalities the angle is less than approximately 45 °.
    [068] As noted earlier, each of the raised screen components 420 can be arranged in a staggered or offset pattern in the screen panel assembly 400. As shown in Figure 4C, which is a plan view of the screen panel assembly 400 shown in Figure 4A, the center line of each raised screen component 400, that is, the wedge surface 410 and / or the wear plate 410w of each respective frame 403 (see Figure 4B), can be aligned with the gap flow rate 415 between frames 403 of an adjacent pair of raised web components 420 which are immediately upstream of them. In the illustrative embodiment of Figure 3C, each flow span 415 can be scaled in relation to the adjacent flow spans 415 so that the wedge surfaces 410 and / or wear plates 410w of each respective frame 403 act to change the flow path of the material mix on the screen panel assembly 400 and thereby form a serpentine or indirect flow path 417 that generally moves along the flow direction of material 418. It should be understood that, In light of the general operating characteristics of typical vibratory separation equipment, for example, vibrating screens, the solid particles that are separated by the screen assembly 400 will typically tend to move along the serpentine flow path 417 as the panel assembly is installed. screen 400 is vibrated along the displacement vector 412 during operation.
    [069] Figure 4D is a plan view approaching the illustrative screen panel 402 and the raised screen component 420 shown in Figure 4B and described above. Additionally, Figure 4E is a front elevation view of screen panel 402 when viewed along the line of sight “4E-4E” of Figure 4D, and Figure 4F is a side elevation view of screen panel 402 when viewed along the line of sight “4F-4F". As shown in Figure 4D, the front edge 402e can be perpendicular to the longitudinal geometric axis 401 (and, that is, the displacement vector 412), in this case, the screen surface inclined 422 will be aligned with a plane that is oriented at an angle 426 that is perpendicular to the displacement vector 412. However, as noted above, the front edge 402e of the screen panel 402 - and the plane of the inclined screen surface 422 - will not it needs to be perpendicular to the longitudinal geometric axis 401. Therefore, in at least some embodiments, the inclined screen surface 422 can be aligned with a plane that is oriented at an angle to a plane that is perpendicular to the longitudinal axis 401 and the veto displacement r 412, in which in some modalities the angle is less than approximately 45 °.
    [070] Also as shown in Figure 4D, the partial flow spans 415 are positioned adjacent to each side panel 406 of the raised screen component 420. Additionally, as shown in Figures 4D to 4F, the wedge surface 410 and / or the wear plate 410w can typically be positioned substantially along the centerline of frame 403, where frame 403 can be height 403h, and side panels 406 can be substantially triangular in shape.
    [071] In certain exemplary embodiments, the frame 403 of each raised screen component 420 can be constructed as an integral component of an individual screen panel 402. In other embodiments, the 403 frames can be separately constructed and coupled to the panel assembly 400 fabric by adhesives, cold welding, welding or other coupling methods. In addition, in at least some embodiments, the frames 403 for individual raised screen components 420 can be removably attached to the screen panel 402, thereby facilitating the removal of frames 403 from the screen panel assembly 400 for replacement or repair as needed regardless of other elevated screen components, that is, without replacing the entire 400 screen panel assembly.
    [072] In operation, the screen panel assembly 400 can be displaced, or vibrationally accelerated, along displacement vector 412 while a mixture of fluid, for example, a mixture of drilling fluid and drill cuttings, is fed through the screen panel assembly 400 in the direction of material flow 418. As the material mixture moves along the screen panel assembly 400, at least some of the fluids that make up the material mixture may pass through the surfaces of the screen 421 of the screen panels 402, the vertical screen surfaces 406 and the angled screen surfaces 422. Solid particles of the mixture that cannot pass through the surfaces of the screen 421, the vertical screen surfaces 406 or the inclined screen surfaces 422 can tend to rest on the surfaces 421 of the screen panels 402. The combination of material flow in the general direction 418 and the vibrational displacement of the screen panel assembly 400 around it Thus, the displacement vector can cause the solid particles to move continuously through the screen panel assembly 400 along the serpentine flow path 417 (see Figures 4B and 3C).
    [073] Figures 5A to 5D are various perspective views of an exemplary modular construction configuration of a raised screen component 520 according to an illustrative embodiment of the present disclosure. As shown in Figure 5A, the exemplary raised screen component 520 includes a plurality of angled front-side screen subpanels 522, side panels 513 and a plurality of rear-side vertical screen subpanels 506, which can be oriented and configured accordingly. with any of the elevated screen component embodiments disclosed in the present invention. For example, the raised screen panel assembly 520 may include a frame 503 that is adapted to support the inclined screen subpanels 522, vertical screen subpanels 506 and side panels 513. Additionally, as shown in Figures 5A to 5D, the frame 503 can include lower front and rear support members 507a and 507b that can be positioned, that is, aligned with, on the top surface of a screen panel (not shown; see, for example, screen panel 202 shown in Figure 2B). In addition, frame 503 may also include front and rear support members 509a and 509b that can extend upwardly from the top surface of the screen panel. In addition, support members 507a / b and 509a / b can be attached to side panels 513.
    [074] In certain embodiments and, as shown in Figures 5B to 5D, the front and rear support members 507a / b and 509a / b can have a channel-shaped configuration and the like, which can be adapted to receive a respective frame. 522f or 506f screen subpanel. For example, angled front-side screen subpanels 522 may include a screen sub-panel frame 522f, while vertical rear-side screen subpanels 506 may include a screen sub-panel frame 506f. In some embodiments, the front side and bottom front channel support members 507a and 509a, respectively, can be adapted to receive the 522f screen subpanel frames, that is, the inclined screen subpanels 522. Additionally, the members 507b and 509b rear lateral and lower channel support brackets, respectively, can be adapted to receive the 506f screen subpanel frames, that is, the 506 vertical screen subpanels. In addition, in at least one example embodiment, the front and rear channel support members 507a / b and 509a / b can be adapted to slide the 522f screen subpanel frames (as shown in Figure 5B) and / or the 506f screen subpanel frames ( as shown in Figure 5C).
    [075] Once installed, the screen subpanel frames 522f and / or 506f can be attached to the frame 503, that is, to the front and rear support members 507a / b and 509a / b, and to the adjacent screen subpanel frames 522f and / or 506f, through adhesives, cold welding, welding, mechanical fasteners or any other fastening methods known in the art. In certain illustrative embodiments, the frame 503 consisting of the channel-shaped support members 507a / b and 509a / b illustrated in Figures 5A to 5D and described above may allow individual screen subpanels 522 and / or 506 to be replaced without replacing the entire the raised screen component 520. Additionally, as shown in Figure 5C, the rear vertical screen subpanels 506 may include portions of a wedge surface, or ditch 510, that can be constructed from a solid material for the purpose to avoid undue wear of the 506 screen subpanels during operation. In certain embodiments, the individual screen subpanels 522 and / or 506 can be replaced without removing the raised screen portion 520 from a larger screen panel assembly, such as the screen panel assemblies 200, 300 and / or 400 described above .
    [076] Figures 6A to 6C are various views of a modular construction configuration of a screen panel assembly 600 that includes a plurality of raised screen components 620 according to another illustrative of the present disclosure. More specifically, Figure 6A is a perspective view of a partial screen panel assembly 600 that includes a plurality of raised screen components 620 that can be modularly assembled to form the complete screen panel assembly 600, Figure 6B is a plan view of the screen panel assembly shown in Figure 6A, and Figure 6C is a perspective view in approach of a single raised screen component 620 shown in Figure 6A.
    [077] As shown in Figures 6A and 6B, the screen panel assembly 600 can include a plurality of substantially identical screen subpanels 602, each of which can be connected to adjacent screen subpanels 602 by a plurality of connectors 602c. In some embodiments, each of the screen subpanels 602 may have a substantially rectangular shape and may include a raised screen component 620 removably attached thereto, as will be further discussed in relation to Figure 6C below. In addition, as with the screen panel assemblies 200, 300 and 400 described in the present invention and illustrated in Figures 2A to 4F, the screen subpanels 602 can be arranged in a staggered or offset pattern, so that a flow gap 615 between immediately adjacent pairs of raised screen components 620 can be substantially aligned with an axis of raised screen component 620 in an adjacent row downstream thereof. In this way, the flow of a mixture of materials along a nominal material flow path 618 can be allowed to flow around the sides of each raised screen component 620 and through a corresponding flow gap 615, flowing from there. form, through the screen panel 600 on a substantially serpentine type 617 flow path, as described in greater detail below.
    [078] It should be understood that the configuration of the partial screen panel assembly 600 shown in Figures 6A and 6B is intended to be exemplary only, and is not limiting to the scope of the material currently disclosed. For example, as shown in Figures 6A and 6B and noted above, each of the plurality of screen subpanels 602 that make up the partial screen panel assembly 600 includes a respective raised screen component 620 attached thereto. However, such a panel configuration is illustrative only, due to the fact that at least some of the 620 screen subpanels may not include a respective 620 raised screen component. In addition, the 620 screen subpanels without such 620 raised screen components can be randomly distributed over the screen panel assembly 600 or can be distributed through the screen panel assembly in a recognizable and / or repeated pattern or sub-pattern.
    [079] Referring now to Figure 6C, each screen subpanel 602 may include a subpanel base 602b which may have a plurality of partial circular openings 602p arranged around the perimeter thereof, as in each corner and along at least some sides of the subpanel base 602b. In certain embodiments, the partial circular openings 602p correspond to, that is, fit into, similarly positioned and shaped partial circular openings 602p in adjacent sub-panels of screen 602, thereby forming a complete circular opening that can be adapted to receive a corresponding connector 602c, thus facilitating the interconnection of adjacent screen subpanels 602.
    [080] In some embodiments, the raised screen component 620 disclosed in Figure 6C may include a frame 603 that has a plurality of frame members. For example, frame 603 can include a lower front frame member 607f, upper front frame members 609, lower side frame members 607s and a rear frame member 610, which may also be called wedge frame member 610. In at least some embodiments, an additional wedge wear plate 610w can be attached to and positioned between each of the lower side frame members 607s and the rear frame member 610, thereby providing additional wear resistance during the operation of the 600 screen panel assembly.
    [081] As shown in Figure 6C, the lower frame members 607f and 607s can be aligned with the plane of the base screen subpanel 602b, thereby forming a triangular base of the raised screen component 620 that travels substantially horizontally across of the upper surface of the base 602b. In certain embodiments, the upper frame members 609 may extend upwardly from the corners of the triangular base of the raised screen member 620 which are defined by the intersections of the lower side and front frame members 607f and 607s. In addition, the rear frame member 610 can extend upwardly from the corner of the triangular base of the raised screen component 620 which is defined by the intersection of the lower side frame members 607s. Additionally, the upper front frame members 609 and the rear frame member 610 can extend upward as noted above for the purpose of meeting at a common upper point or apex 603u, thereby substantially forming a raised web component 620 which is shaped like a modified triangular prism.
    [082] For clarity of the drawing, the tiling material was not illustrated in Figures 6A to 6C. However, the tiling material can be arranged on the upper surface of the base screen subpanel 602b, as shown in Figure 6C by element numbers 621. Additionally, the tiling material can also be arranged on the front plane of the raised screen component 620 which is defined by the lower front frame member 607f and the upper front frame members 609, thereby defining an inclined screen surface 622, like the inclined screen surfaces 222, 322, 422 or 522 described above. Additionally, the tiling material can be arranged on two lateral planes of the raised screen component 620 which are defined by a lower side frame member 607s, an upper front frame member 609 and the rear frame member 610, thereby defining , rear or side screen surfaces 609. In addition, in some embodiments, the tiling material can also be arranged over the triangular opening at the bottom of the raised screen component 620 which is defined by each of the three lower frame members 607f and 607s, identified by element number 622, although in other exemplary embodiments, aperture 622 may not have tiling material arranged therein.
    [083] As shown in Figure 6C, a plurality of tabs 620t can extend from the lower frame members 607f and 607s. In some embodiments, the base 602b of the screen subpanel 602 can have a plurality of corresponding slots 602s, each of which can be adapted to receive a corresponding tab 620t. In at least one embodiment, one or more of the tabs 620t and one or more corresponding slots 602s can be additionally adapted to have an interference fit, so that the frame 603 of the raised screen component 620 fits in place on the base 602b of the screen sub-panel 602. In addition, such a configuration facilitates relatively easy removal and replacement of damaged and / or defective (e.g. clogged) elevated 620 screen panel components.
    [084] Although the modalities described above illustrate screen assemblies that have an identical frame assembly arrangement, it should be understood by those of ordinary knowledge after a thorough reading of the present disclosure that, in certain embodiments, a variety of different screen components can be used in a single screen panel assembly. In addition, the illustrative elevated screen components disclosed in the present invention may be present only in a portion of a particular screen panel assembly while other portions of the screen panel assembly may be substantially flat or have other screen arrangements.
    [085] The particular modalities disclosed above are only illustrative, as the invention can be modified and practiced in different, but equivalent, apparent ways to those skilled in the art that have the benefit of the teachings in this document. For example, the method steps presented above can be performed in a different order. In addition, none of the limitations are intended for the details of construction or design shown in this document, other than as described in the claims below. Therefore, it is evident that the particular modalities disclosed above can be altered or modified and all such variations are considered within the scope and spirit of the invention. Consequently, the protection sought in the present invention is as set out in the claims below.
