    Description FIELD OF THE INVENTION
    The invention relates to an operating and changing device for a filter body with a particulate filter, each having the features according to the preamble of claim 1 and with the features according to the preamble of claim 2. The filter body is located within the operating and changing device a designated and operational filter position. The filter body preferably has a filter body symmetry axis. By the (filter body) symmetry axis is meant a reference and / or directional line or point set, which may include, for example but not necessarily, features of a geometric axis at least in sections. At least one particle filter for removing particles from a particle-loaded fluid is integrated in the filter body. The particulate filter may be a HEPA filter (HEPA: High Efficiency Particulate Arrestance, meaning: high-performance particle separation, suspended matter filter), for example a Class 14 HEPA filter. An EPA fil (EPA: Efficient Particulate Air Filter, meaning particle filter) or a ULPA filter may be provided (ULPA: Ultra Low Penetration Air, high-performance particulate filter). The fluid flow can be formed as a compressed air flow (with overpressure relative to the normal pressure) or as a suction flow (with suppression relative to the normal pressure). The particles may be, for example, dusts. The filter body has at least one filter body opening through which fluid can flow (for example on the front side and / or in a jacket section) and at least one fluid-tight filter body wall section (for example the jacket sections adjoining the front sides).
    The operating and changing device comprises a flow-through by the fluid and otherwise fluid-tight housing (containment) with a flow channel. The flow channel can be limited by the housing or be formed or be arranged in the housing with its own channel boundary. The channel may have a (right-) angled, a round or an oval cross-section. In the flow channel of the filter body can be arranged so that the particle filter can be flowed through by the fluid. In the housing, a plurality of (in particular parallel) flow channels can be arranged. The cross section of the filter body substantially corresponds to the cross section of the channel, so that the filter body fits into the channel so that there is no or only a small distance between the filter body and channel inner wall.
    In the housing, the flow channel is arranged with at least one flow inlet for flowing the particle-loaded fluid and at least one flow outlet for discharging the particle-relieved fluid so that the fluid flow passes between the flow inlet and flow outlet in the flow channel through the particle filter of the filter body. At a conceivable reversal of the flow direction, the fluid flows in through the flow outlet and out of the flow inlet.
    It can also be provided that in the channel two filter body are arranged one behind the other as a double filter. Usually one of the two filters serves as a safety filter if the other one fails. The filter bodies have a common, longitudinally oriented, expansion and / or filter body axis of symmetry. In this case, "longitudinal direction" essentially means the longitudinal direction of the containment, along which the flow can run at least in sections. In each filter body, a particulate filter is integrated in each case. In this case, the operating and exchanging device comprises a housing through which the fluid can flow with a flow channel in which a first filter body with a first particle filter and a second filter body identical in construction, in particular to the first filter body, with a second particle filter, which is preferably identical to the first particle filter can be arranged so that, for example, first of the first particle filter and / or the second particle filter can be flowed through by the fluid. The fluid flow can pass between the flow inlet and the flow outlet in the flow channel through the first particle filter of the first filter body and (from there) through the second particle filter of the second filter body. If the filter change is to take place with filters that are not identical, the replacement filter may for example be longer or shorter or more stable or lighter than the filter to be replaced. If the filters involved are not identical, the filter body change can be accompanied, for example, by a filter class change, for example from HEPA class 14 to HEPA class 12 or vice versa. The particulate filter of the replacement filter could, for example, have a higher or a lower filter class than the particulate filter of the filter body to be replaced.
    The device may comprise a housing having at least two housing sections, each housing section comprising the features described above. The flow channel according to the first housing section can be connected in fluid-parallel with the flow channel of the second housing section in series or fluidically.
    The invention further relates to a filter body with a particle filter or consisting of a particle filter for removing particles from a particle-loaded fluid having the features according to the preamble of claim 8 or according to the preamble of claim 9.
    The invention also relates to a method for (almost) constant flow change of a particle filter used in a fluid flow according to claim 10 and / or according to claim 11.
    Finally, the invention relates to a conveying device for conveying a product by means of a fluid flow in a conveying channel with the features according to the preamble of claim 14 and / or with the features according to the preamble of claim 16. Accordingly, the fluid flow flows through a filter device with at least a filter body.
    TECHNOLOGICAL BACKGROUND
    The problem with transporting or conveying dusty products by means of a, in particular gaseous, transport fluid is often the effort in connection with the cleaning / filtering of the transport fluid. The invention is therefore based on the object to reduce the effort when cleaning / filtering a fluid.
    PRESENTATION OF THE INVENTION
    The cleaning of the fluid is carried out regularly with EPA, HEPA or ULPA filters, but they must be replaced after some time. The effort associated with the filter change can be significantly reduced with an operating and changing device for a filter body according to claim 1, whereby the total cost in connection with the cleaning / filtering of the fluid is reduced. Embodiments of the invention will become apparent from the dependent claims.
    The flow channel preferably has a channel axis of symmetry which is parallel to the filter body axis of symmetry, in particular collinear. Similar to the filter axis of symmetry axis, the channel symmetry axis means a reference and / or directional line or point set which, for example-but not necessarily-can have features of a geometrical axis at least in sections. For example, based on this reference line (channel axis of symmetry), the flow inlet and the flow outlet of the flow channel are offset from one another and / or arranged at a distance from one another. If a cylindrical symmetry is given, or a cylinder-like shape of the containment, an (exclusively) radial offset between the flow inlet and the flow outlet can be provided, so that the flow inlet and the flow outlet are arranged opposite one another.
    The flow channel, in particular the flow channel and the housing, comprise a filter insertion opening and a filter ejection opening. Through the filter ejection opening, the filter (body) is removable from the device, such as by falling out, pushing out or pushing out, generally by moving out. At the filter removal opening or filter ejection opening, an (old) filter reservoir can be arranged, for example as a pipe or chamber or bag, in which the (old) filters are at least temporarily stored (temporarily). The filter insert opening and the filter ejection opening can be arranged in a geometrical alignment, for example along the channel axis of symmetry. A change of the particulate filter takes place by replacing the filter body with a replacement filter body with a replacement filter. The replacement filter body is pushed through the insertion opening in the flow channel. The filter body to be replaced can be pushed out of the channel through the ejection opening by inserting the replacement filter body. During the insertion / ejection of the filter body, the flow inlet and / or the flow outlet are fluidly blocked by the fluid-tight filter body wall section until the replacement filter body has reached the filter position, so that the flow channel is not opened when the particle filter is changed, and so the replacement of the particulate filter almost free of interruption takes place.
    When in accordance with the housing positioned filter body are the filter body opening respectively the filter body openings in the flow channel between the flow inlet and the flow outlet. When the filter body is displaced due to shifting or shifting, at least one filter body wall section is located between the flow inlet and the flow outlet, as a result of which the flow channel is sealed in a fluid-tight manner. Preferably, a filter body wall section is located sealingly in front of the flow inlet and another filter body wall section sealingly in front of the flow outlet during filter pushing.
    The flow channel, so to speak, forms a lock during the filter change. The duration of the air arrest within the channel and during the filter change is shorter than about 10 seconds, especially shorter than about 1/10 second. The flow channel or the housing may comprise a plurality of flow inputs and a plurality of flow outlets. For example, three flow openings may be provided: two on the inflow side and one on the (opposite) outflow side, or one on the inflow side and two on the outflow side.
    The effort in connection with the filter change can also be reduced with an operating and changing device with multiple filters / filter bodies according to claim 2.
    Accordingly, the flow channel preferably has a channel axis of symmetry which is parallel to the filter body axis of symmetry, in particular collinear. With respect to the channel axis of symmetry, the flow inlet and the flow outlet are offset from each other and / or arranged at a distance. The flow channel, in particular the flow channel and the housing, comprise a filter insertion opening and a filter ejection opening, wherein, preferably, the filter insertion opening and the filter ejection opening are arranged along the channel axis of symmetry in a geometrical alignment, for example at the end faces of the housing. If the floor plan of the housing includes a bend or a curve, the filter body along the bend / curve are arranged one behind the other. A particle filter change takes place by inserting a replacement filter body with a replacement filter into the flow channel. The replacement filter body is pushed through the insertion opening in the channel. The first filter body is slidable by pushing the replacement filter body to the original position of the second filter body. By moving the first filter body and the second filter body with the particle filter to be replaced is displaced. By inserting the replacement filter body and moving the first filter body, the second filter body with the particle filter to be replaced can be pushed out of the channel through the ejection opening. After the filter change, the first filter body assumes the position of the second filter body in the flow channel. During the insertion / ejection of the filter body, the flow inlet and / or the flow outlet is fluidly blocked by the fluid-tight filter body wall section at least until the second filter body has assumed the original filter position of the first filter body and the replacement filter body has the original position of the second filter body that when changing the particulate filter, the flow channel is not opened, and so that the replacement of the particulate filter is virtually free of interruption. In this filter (body) arrangement, more than two, for example, three, four, five, and more, linearly arranged filter body may be provided in the flow channel. Involved in the filter change are always the first and the last filter body in the filter body row: The last is pushed out by the arranged before when pushing, the first becomes the second, the second to the third, etc.
    According to one embodiment it can be provided that one or more sealing portions, in particular seals, are arranged between the flow channel and the filter body or the filter bodies. The flow inlet or the flow inlets and the flow outlet or the flow outlets are arranged offset relative to one another in relation to the flow direction or relative to the symmetry direction. As a result of the offset, when the filter bodies are displaced, a closure or constriction of the openings is achieved either on the inflow side or on the outflow side or on both sides, in particular by one or more filter bodies. A flow interruption or an air stoppage is particularly effectively avoided if during the displacement of the filter body, the flow passes through only the filter that remains throughout the filter change in the channel (for example, the first filter). During the change and when moving the filter so briefly takes over the remaining in the channel (first) filter only the filter function of the device. At least one flow inlet and / or at least one flow outlet are fluidically blocked by the first and / or the second filter body during displacement of the filter body. For this purpose, based on the axis of symmetry and / or with respect to the flow direction, a spatial offset of at least one input relative to at least one output may be expedient. The width of the offset can be determined by the geometry of the filter body used. For example, the flow opening can be arranged on the outflow side in the region of the filter insertion opening or in the region of the filter ejection opening, while the flow opening on the inflow side is arranged substantially centrally or almost centrally between the filter insert and filter ejection openings.
    For packing the removed filter body may be provided on the outside of the housing in the region of the filter ejection opening arranged hose device. The packaging is expedient insofar as the filter to be removed in enriched in most Wechselanlässen with particles from the fluid and thus "full" is. Since the particles regularly pose a health risk (dusts in the pharmaceutical industry contain active ingredients, dusts in the industry at least partly consist of harmful dusts), the expense of filter replacement is significantly reduced by the packaging of the filter / filter body immediately following the change. The filter body with the removed filter can be arranged for this purpose in a hose section, which can come about from a supply of tubing, which is arranged on the housing. The hose reservoir surrounds a peripheral housing portion, whereby the housing is the dispenser for the hose.
    Preferably, a tubular film is arranged on the hose device respectively on a housing portion, which forms in particular a hose supply. The pushed out of the filter body filter tube section may be closed with the filter body therein, for example by a clamp, by a lacing or by (hot) sealing.
    In order that the contents of the containment between two filter replacement measures is better protected, whereby the filter durability and thus the change effort is reduced, at least one closure device for closing the filter inlet opening and / or the filter ejection opening can be provided. The device may comprise a hose closure device with which the hose of the hose device is closable, in particular closable and separable.
    The operating and changing device according to the invention may comprise at least one safety device. By the safety device operating errors when operating the operating and changing device should be avoided. A possible operator error would be, for example, pulling (pulling) a filter (the first filter) instead of pushing the filter or filters as described above. Such an operating error could be accompanied by an opening of the flow channel or the containment, which can lead to contamination of the channel and / or the environment of the changing device as well as overload / damage of the devices connected to the device. In order to prevent this, for example, a recharging device (outside) may be provided on the housing into which the (replacement) filter body to be inserted as intended can be inserted, and which at least supports the insertion of the filter body and ensures the exact positioning of the (replacement) filter body. The recharging device may comprise at least one guide, such as a rail, for the filter body with which the (replacement) filter body can be pushed into the housing. Tilting or tilting of the filter body when pushing in are avoided, which in turn means that the user does not come up with the idea to perform the filter change differently than intended. Alternatively or cumulatively, a movement barrier could be provided in the housing, which allows the movement of the filter bodies in a first (intended) direction, and which inhibits the movement of the filter bodies in the opposite direction ("wrong" direction). For this purpose, a particular spring-loaded hook or folding mechanism may be provided in the housing of the operating and changing device, which folds when moving the filter body in the intended direction and allows moving the filter body, and blocks the filter body in the unfolded state, when the filter body contrary to the intended Direction is being moved.
    The effort in connection with the filter change can be reduced with a filter body with a particle filter for removing particles from a particle-loaded fluid according to claim 8. Accordingly, the filter body has a body geometry which is suitable for the filter body being usable in an operating and changing device described here. Preferably, the filter body may have a conventional substantially cylindrical geometry, i. H. the end faces of the filter body are (circular) round. Alternatively, a cuboid geometry may be provided, so that the end faces are rectangular or square. The cross section could optionally be triangular, so that the filter body has a prismatic geometry. The reference line of the filter body referred to here as the "symmetry axis" could, for example, pass through an excellent point such as the (geometric) center of gravity of a cross-sectional area in angular geometry, and preferably i. W. parallel to the direction of the longitudinal extension of the body.
    The effort in connection with the filter change can be reduced optionally or additionally with a filter body with a particle filter for removing particles from a particle-loaded fluid according to claim 9. Accordingly, the filter body / particle filter comprises at least one sealing section, in particular a seal. The sealing portion or the seal may be formed by a portion of the particulate filter or by a portion of the filter body. The sealing section or the seal seals the channel from the housing fluidly. The filter may be formed as a component that includes both the properties of the particulate filter and the sealing properties of the filter housing. In this case, the particle filter would not only have (dust) filtering but also (fluid) sealing function in the housing.
    The effort in connection with the filter change can also be reduced by a method according to claim 10. The method serves for virtually constant flow change of a particle filter used in a fluid flow. The particle filter is arranged in a filter body and the filter body in a flow channel through which the fluid can flow. For filter replacement, a replacement filter body with a replacement filter is pushed into the channel via a filter insertion opening. By pushing the replacement filter body into the flow channel, the filter body to be replaced is pushed out of the flow channel through a filter ejection opening. During the displacement of the filter body to be replaced, the flow channel is closed by a fluid-tight wall section of the filter body, so that the flow channel or the containment is not opened by the filter change.
    The effort in connection with the filter change can also be reduced by a method according to claim 11. A first particle filter is arranged in a first filter body and the first filter body in a flow channel through which the fluid can flow together with at least one further, second filter body with a second particle filter in succession / side by side. For filter replacement, a replacement filter body with a replacement filter is pushed into the channel via a filter insertion opening. By pushing the replacement filter body into the flow channel, the first filter body and the second filter body to be replaced are displaced in the flow channel in the direction of a filter ejection opening. By moving the second filter body is pushed out of the channel through the filter ejection opening.
    Preferably, the pushed-out filter body is packed in a film tube, wherein the film tube a, in particular endless, tubular film supply is removable. In this context, "endless" means a hose supply which comprises a large number (approximately 50, preferably approximately 200 or more) hose sections before the hose supply is exhausted. A hose section in this case has a hose length which corresponds approximately to twice the length of a film body, possibly even only 1.5 times this length. The film tube can, after the packaging of the pushed-out filter, in particular tight, be closed, and preferably separated after closure.
    The effort in connection with the filter change can also be reduced with a conveying device according to claim 14 or claim 16. The conveying device serves to convey a product by means of a fluid flow in a conveying channel, in which the fluid stream flows through a filter device with at least one filter body. The conveying device comprises an operating and changing device described here for a, in particular here described, filter body. A filter can be changed in the conveying device according to the invention by a filter change method described here.
    The above-mentioned and claimed and described in the embodiments according to the invention to be used components are subject to their size, shape design, choice of materials and technical design no special conditions of exception, so that the well-known in the field of application selection criteria can apply without restriction.
    Further details, features and advantages of the subject matter of the invention will become apparent from the dependent claims, as well as from the following description and the accompanying drawings, in which - by way of example - an embodiment of an operating and changing device is shown. Also, individual features of the claims or of the embodiments may be combined with other features of other claims and embodiments.
    BRIEF DESCRIPTION OF THE FIGURES
    In the drawing show
    1 is a Filterbetriebs- and changing device in perspective view,
    Fig. 2 shows an operating and changing device in a side view, and
    Fig. 3 to 6 are sectional views of a device according to FIG. 2, each in different operating conditions. DETAILED DESCRIPTION OF EMBODIMENTS
    Fig. 1 shows a perspective view of an operating and changing device 1 for (HEPA) filter 2. The filter 2 may be an EPA, HEPA or ULPA filter (ULPA: Ultra Low Penetration Air, high performance suspended matter -Filter). A fluid, for example a gas-containing suction flow, flows through the device 1. Alternatively, a gas stream with a gas pressure can be passed through the device 1. In the following, the fluid is referred to as suction flow. Fig. 1 shows the housing 6 of the device 1. The housing 6 forms a channel 8, through which the suction flow is feasible.
    With the gas-containing suction flow products or product particles can be conveyed in a conveyor, not shown here. The device 1 can be connected to a conveying device, for example in the area of suction flow generation or for suction flow preparation. The suction flow passes through the filter operation and change device 1, wherein the suction flow of HEPA filters 2, which are arranged within the device 1, is cleaned of (dust) particles.
    A side view of the device 1 can be seen in FIG. 2. In Fig. 2, flow inlet 3 and flow outlet 4 can be seen. The flow inlet 3 and the flow outlet 4 each comprise a flange for connecting the openings 3, 4 to conduits or channels (not shown) for passing the suction flow. According to FIG. 2, the inflow side of the device 1 is above, the outflow side is arranged on the underside 5 of the device 1. On the bottom there are also fastening means for securing the device 1 on a base or on a pump housing.
    FIGS. 3 to 6 can be seen lateral sectional views of the device 1 according to FIGS. 1 and 2. FIGS. 3 to 6 each show two HEPA filters 2, 2 'arranged next to one another. The filters 2, 2 'are each arranged in a filter body 7, 7'. Filter 2 and filter 2 'are identical, as are filter body 7 and filter body 7 ". With reference to the axis of symmetry x (see also Fig. 2) of the housing 6 of the device 1, the filter bodies 7, 7' with the filters 2, 2 'in The filter bodies 7, 7 'are arranged next to one another in relation to the flow direction.
    The filter body 7, 7 'are located in a channel 8, which is formed by the housing 6. Channel 8 and filter body 7, 7 'have almost the same cross section, so that the filter body 7,7' sealing in the channel 8 can be arranged. Accordingly, the suction flow passes only through the HEPA filters 2, 2 'and not past the filter material or not past the filter bodies 7, 7'. The flow is symbolized by arrows in FIG. The flow passes through the flow inlet 3 into the particle filter 2 'of the filter body 7 ", from where the flow reaches the region between the filter body 7 and the filter body 7' via a filter body opening in the end face of the filter body 7 'The flow then reaches the flow outlet 4 If the filter body 7 and therefore also the filter body 7 'are displaced (to the left in Fig. 3), the flow outlet 4 and flow inlet 3 are closed in a fluid-tight manner by wall sections of the filter body T. This means that during displacement, ie when changing, the filter body 7, 7 'the flow channel in the housing 6 of the device is not opened, the particle-loaded fluid flow does not enter the surroundings of the changing device even when the filter body is being changed, ie with the housing open at the end is carried out.
    The symbolized in Fig. 3 flow can also be in the opposite direction, d. H. It can also be provided a bypass, so that during the filter change the first arranged in the housing ("parked") filter (filter 2) is briefly flowed through the bypass until he then alternately in the proper position sitting. The bypass may be partially disposed in the housing and / or partially outside the housing. The bypass may comprise at least its own flow opening of the housing.
    A replacement filter body 7 "is intended to replace one of the filters (7, 7") used: The procedure is as follows: First, a filter insertion opening 9 on the housing 6 is removed by removing a closure device 14 The opened state is shown in Fig. 4, the closed in Fig. 3. The replacement filter body 7 "with the new, unused HEPA filter 2" is pushed laterally as shown in FIG. 4 in the housing 6 of the device 1 This is possible since replacement filters (7 "and 2") and the filters (7, 2; 7 ', 2') used are of identical construction, in particular with regard to the geometric dimensions.
    By inserting the replacement filter 7 "along the axis of symmetry x (according to FIGS. 3, 4, 5 and 6, then to the" left "), the filters 7, 7 'inserted in the housing 6 along the direction of the axis of symmetry x (FIG. also after

    «Left»). The filter which is closest to the filter ejection opening 10 (filter 7 ') is pushed out of the housing 6 and from there enters a section 12 of the hose 11. This state is shown in FIG. 5. The filter body T with filter 2 'was pushed out of the housing 6. Filter body 7 with filter 2 takes the original position of the filter body 7 'with filter 2' a. At the original position of the filter body 7 with the filter 2 now sits the replacement filter body 7 "with filter 2". The exchanged or removed filter T, 2 'is packed in the tube section 12 of the tube. The hose 11 is stored on the housing 6 insofar as a hose supply 13 is arranged on the outside of the housing. From the hose supply 13, a hose section 12 can be removed at each filter change. 6, the closed by lacing or setting hose section 12 can be removed. The tube portion 12 can be separated from the tube 11 with a suitable release agent (knife, scissors, filament). The removed and regularly contaminated filter 2 'in the filter body 7' can now be safely disposed of without the particles collected in the filter 2 ', 7' reaching the surroundings of the device 1. If the filter class of HEPA filters (2, 2 ', 2 ") are changed (class 12 instead of class 14, for example), two replacement filters would be 2" with new HEPA class ready and the method described above would be twice, respectively with the new filter classes.
