However, these embodiments can be implemented in various forms and are not limited to the embodiments described herein. It is to be understood that these embodiments serve to fully and thoroughly disclose the present application and are intended to fully convey the concepts of these embodiments to those skilled in the art. In the accompanying drawings, the thickness of the layers and regions is shown enlarged for clarity. Like reference numerals represent like devices, and therefore their description is omitted.

[0023] With reference to the Fig. 1 to 5, a separation device for dry filtration is provided according to a specific embodiment of the present application.

[0024] In particular, the separating device for dry filtration as described in the Fig. 1 to 5, a support frame 2 and a filter device 1, wherein the support frame 2 comprises a frame body 20 and a sealing door 21, wherein the frame body 20 has a vent opening 200, wherein the sealing door 21 is movably connected to the frame body 20 such that the sealing door 21 has a blocking state for blocking the vent opening 200 and an evasive state for evading the vent opening 200, wherein a first cooperation mechanism 22 is arranged on the support frame 2; wherein the filter device 1 is movably arranged relative to the support frame 2 and a second cooperation mechanism 11 is arranged on the filter device 1;wherein the first cooperation mechanism 22 and the second cooperation mechanism 11 cooperate during a movement of the filter device 1 along a predetermined distance towards the vent opening 2 to drive the sealing door 21 such that the sealing door is changed from the blocking state to the avoidance state;

[0025] In the technical solution of this embodiment, when the filter device 1 moves along the predetermined distance toward the vent hole 200, the first cooperation mechanism 22 on the support frame 2 cooperates with the second cooperation mechanism 11 on the filter device. The first cooperation mechanism 22 drives the sealing door 21, so that the sealing door 21 switches to the evasive state, thereby avoiding the vent hole 200, and the filter device 1 performs the filtering work. When the sealing door 21 switches to the locked state, the filter device 1 can be separated from the production line, which facilitates personnel maintenance of the filter device 1 or replacement of filter components and materials in the filter device 1.Through the interaction of the support frame 2 and the filter device 1, the filter material can be replaced during operation, which improves the filter work efficiency and reduces maintenance costs.

[0026] It should be noted that the filter device 1 may move along a predetermined path via a rail provided in a paint mist filter structure of an automobile painting line, or may be moved along a predetermined path via a control module with a wired or wireless control signal.

[0027] In one embodiment of the present application, the frame body 20 is arranged on the paint mist filter structure of an automobile painting line. In the frame body 20, the interior of the paint mist filter structure communicates with the outside environment via the vent 200, and the sealing door 21 avoids the vent 200. The filter device 1 performs the filtration work in the paint mist production line. When the filter material needs to be replaced or maintenance needs to be performed in the filter device 1, the filter device 1 is controlled to move away from the vent 200 along a predetermined distance. The sealing door 21 is changed from the avoidance state to the blocking state after the first cooperation mechanism 22 cooperates with the second cooperation mechanism 11 to facilitate maintenance of the filter device 1.

[0028] As in Fig. 1, Fig. 3 and Fig. 4, the support frame 2 specifically includes a return mechanism 26, which is connected to the sealing door 21. The return mechanism 26 is provided for driving the sealing door 21, thereby switching the sealing door from the evasive state to the locking state. The return mechanism 26 exerts a driving force on the sealing door 21 and automatically returns it to the locking state after the first cooperation mechanism 22 is separated from the second cooperation mechanism 11. As a result, the sealing performance of the filter device is maintained after the filter device 1 exits the vent opening 200, thereby ensuring the sealing performance, preventing the leakage of unfiltered air, protecting the air environment of the workshop, and maintaining the air balance of the paint spraying line. At the same time, operation is simplified and the reliability of the system is improved.

[0029] Optionally, the return mechanism 26 may adopt a spring return mechanism, a cylinder return mechanism, a magnetic return mechanism, etc. After the first cooperation mechanism 22 is separated from the second cooperation mechanism 11, the mutual abutment force between the first cooperation mechanism 22 and the second cooperation mechanism 11 disappears, and the return mechanism 26 drives the sealing door 21 by the return force to move it in the opposite direction, thereby changing it from the avoidance state to the blocking state and blocking the vent 200 again.

[0030] As in the Fig. 1 and Fig. 4, the first cooperation mechanism 22 further comprises a guide rail 221, a counter element 222, and a first tension element 223, wherein the guide rail 221 is arranged on the frame body 20; wherein the counter element 222 is movably arranged on the guide rail 221 along the extension direction of the guide rail 221, so that the counter element 222 has an initial position and an extreme position; wherein one end of the first tension element 223 is connected to the counter element 222 and the other end of the first tension element 223 is connected to the sealing door 21; wherein the counter element 222 can cooperate with the second cooperation mechanism 11, and the counter element 222 can be driven by the second cooperation mechanism 11 to move it from the starting position to the extreme position, so that the sealing door 21 is driven by the first pulling element 223 to change it from the blocking state to the avoidance state.The guide rail 221 is arranged on the frame body 20 and can extend along the predetermined path of the filter device 1. A counter element 222 is arranged in the guide rail 221, and the counter element 222 can slide along the guide rail 221. The guide rail 221 is used to guide the counter element 222 along the predetermined path. The counter element 222 further drives the first pulling element 223 to pull the sealing door 21 into movement. By utilizing the principle of mechanical transmission, the driving force of the second cooperation mechanism 11 is transmitted to the counter element 222, and then the force is transmitted to the sealing door 21 by the first pulling element 223. Thus, the state is automatically changed, the degree of automation of the device is improved, the operation process is simplified, and the practicality and maintenance efficiency of the device are increased.

[0031] It should be noted that the extension direction of the guide rail 221 can also be set to a specific curve. When the counter element 222 abuts the second cooperation mechanism 11, the second cooperation mechanism 11 can drive the counter element 222 to slide along the guide rail 221, so that the counter element 222 moves from the initial position to the extreme position. In the initial position of the counter element 222, the sealing door 21 is locked. As the counter element 222 moves from the initial position to the extreme position, the sealing door 21 also changes from the locked state to the evasive state. At this time, the sealing door 21 gradually opens until it completely evades the ventilation opening 200.

[0032] In one embodiment of the present invention, a plurality of steering gears are provided on the frame body 20. The first tension element 223 can extend close to the frame body 20 via these steering gears, wherein the direction in which the sealing door 21 is driven by the first tension element 223 can be pulled in a predetermined direction by the steering gears. At the same time, the first tension element 223 can be arranged along a predetermined path via these steering gears such that the first tension element bypasses the predetermined path of the filter device 1 and the movement of the filter device 1 is avoided. Preferably, the steering gear is a fixed roller, wherein the plurality of fixed rollers are arranged on the frame body 20.The first tension element 223 is a tension cable whose direction of movement can be changed via the fixed pulley, allowing the vent opening 200 to be blocked or deflected in various directions through the sealing door 21. For example, the tension cable can pull the sealing door 21 to rotate and pull it in a hinged manner, or the tension cable can pull the sealing door 21 to push and pull it in a sliding manner.

[0033] In particular, the second interaction mechanism 11 comprises, as in Fig. 2, a guide element 111, wherein the guide element 111 has a connected state in which it is connected to the counter element 222, and a separated state in which it is separated from the counter element 222, wherein the guide element 111 can drive the counter element 222 and thereby move the counter element 222 from the starting position to the extreme position when the guide element 111 is connected to the counter element 222. The guide element 111 controls the movement of the counter element 222 and thus controls the change in state of the sealing door 21 by the guide element 111 coming into contact with and detaching from the counter element 222.When the guide member 111 moves toward the counter member 222 until the guide member abuts the counter member 222 and causes the counter member 222 to move, the counter member 222 is moved from the initial position to the extreme position, and the sealing door 21 is also changed from the locking state to the escape state, thereby realizing the automation of the replacement process of the filter device 1 and improving the flexibility and response speed of the device.

[0034] In one embodiment of the present application, in a car painting production line, upon completion of car maintenance, the filter device 1 is moved toward the vent opening 200, wherein the guide element 111 cooperates with the counter element 222 to move the counter element 222 along the guide rail 221. The counter element 222 allows the sealing door 21 to be opened quickly and precisely using the first pulling element 223, so that the filter device 1 can be quickly put into the operating state. This reduces the complexity and time required for manual operation.

[0035] As in the Fig. 1, Fig. 3 and Fig. 4, the return mechanism 26 further includes a first sliding groove 261, a first sliding block 262, and a second pulling member 263, wherein the first sliding groove 261 is arranged on the frame body 20, and the first sliding groove 261 extends along the width direction of the opening of the vent port 200; wherein the first sliding block 262 is slidably arranged in the first sliding groove 261, and the first sliding block 262 is connected to the seal door 21; wherein one end of the second pulling member 263 is connected to the first sliding block 262, and the other end of the second pulling member 263 is connected to a driving member 264; wherein the driving member 264 can drive the first sliding block 262 to slide, so that the seal door 21 is driven to change from the avoidance state to the locking state when the guide member 111 is in the separation state.The first sliding block 262 can slide along the first sliding groove 261 in the width direction of the vent opening 200, thereby moving one end of the sealing door 21 along the extension direction of the first sliding groove 261 and switching the sealing door 21 to the avoidance state. When the guide member 111 is separated from the counter member 222, the first sliding block 262 is connected to the drive member 264 via the second tension member 263, and a driving force is applied to the first sliding block 262 by the drive member 264, so that the first sliding block 262 can be moved in the opposite direction in the first sliding groove 261. Thus, the first sliding block 262 can move the sealing door 21 in the opposite direction to switch the sealing door 21 from the avoidance state to the blocking state.The driving force of the drive element 264 is transmitted via the second tension element 263 to the first sliding block 262, which slides in the first sliding groove 261, and the sealing door 21 is thereby finally driven back to the locked state. This ensures the sealing of the device in the maintenance-free state, prevents the leakage of unfiltered air, simplifies the maintenance process of the device, and improves the overall performance of the device.

[0036] Optionally, the drive element 264 is a plumb line that can be moved in the vertical direction of the frame body 20 via the second tension element 263 and the steering transmission element. After the guide element 111 has been separated from the counter element 222, the plumb line can set the first sliding block 262 in motion through its gravity, thus returning the sealing door 21 to the locked state.

[0037] In one embodiment of the present application, the steering transmission element is arranged on one side or both sides of the frame body 20 in the width direction of the ventilation opening 200. At the same time, the sealing door 21 can move along the first sliding groove 261 toward the first pulling element 223. Through this steering transmission element, the first pulling element 223 can pull the sealing door 21 so that it slides along the extension direction of the first sliding groove 261. When the sealing door 21 is in the evasive state, it slides as a whole to one side of the ventilation opening 200.

[0038] Specifically, the return mechanism 26 also includes a second sliding groove 265 and a second sliding block 266. The second sliding groove 265 is provided on the frame body 20, and the second sliding groove 265 extends along the width direction of the opening of the vent 200. The second sliding groove 265 and the first sliding groove 261 are disposed opposite each other on two sides of the frame body 20. The second sliding block 266 is slidably disposed in the second sliding groove 265, and the second sliding block 266 is connected to the sealing door 21. The second sliding groove 265 is disposed opposite the first sliding groove 261 on the other side of the vent 200. The second sliding groove 265 and the second sliding block 266 perform the same functions as the first sliding groove 261 and the first sliding block 262.The second sliding block 266 is also connected to one side of the sealing door 21, so that the top and bottom of the sealing door 21 are respectively pulled by the sliding blocks. This dual sliding groove and sliding block design improves the stability and accuracy of the movement of the sealing door 21, ensures smooth opening and closing, improves operational reliability, prevents the sealing door 21 from tilting or jamming during movement, and ensures the normal operation of the device. At the same time, the lateral movement of the sealing door is effectively limited, allowing the door panel to move only along a predetermined distance. This increases the reliability and efficiency of the entire system.

[0039] As in Fig. As shown in Figure 2, the filter device 1 comprises a housing 12 and a filter assembly, wherein the housing 12 has a receiving chamber 100, wherein the receiving chamber 100 has an air inlet 101 and an air outlet 102, and wherein the air inlet 101 is arranged corresponding to the sealing door 21 when the sealing door 21 is in the avoidance state; wherein the filter assembly is arranged in the receiving chamber 100, and a filter material is arranged in the filter assembly, and the filter assembly is provided at least for filtering the air in the paint spraying chamber. The air inlet 101 and the air outlet 102 each serve for air supply and exhaust. The air inlet 101 serves primarily to receive paint mist air from the paint spraying chamber, while the filtered, clean air is discharged to subsequent process sequences through the air outlet 102.When the sealing door 21 is in the evasive state, the position of the air inlet 101 is fully aligned with the vent opening 200. The filter component is located inside the receiving chamber 100 of the housing 12, and the filter component is used to filter the air entering the paint spraying room through the air inlet 101, capture and remove paint mist particles, and thus purify the air.

[0040] As in the Fig. 1, Fig. 3 and Fig. 5, the frame body 20 comprises a first frame body 23, a second frame body 24 and a third frame body 25, wherein the plane in which the first frame body 23 is located is arranged parallel to the upper end of the housing 12, wherein the first frame body 23 is formed by a plurality of support rods 201 which are connected to each other in series end-to-end, and a guide rail 221 is arranged on the first frame body 23; wherein the plane in which the second frame body 24 is located is arranged parallel to the air inlet 101, wherein the second frame body 24 has the vent opening 200, and the second frame body 24 is formed by a plurality of support rods 201 which are connected to each other end-to-end in series, wherein the sealing door 21 is arranged on the second frame body 24, and the air inlet 101 and the vent opening 200 are arranged opposite each other,when the sealing door 21 is in the escape state; wherein the plane in which the third frame body 25 is located is arranged parallel to the air outlet 102, wherein the third frame body 25 is formed by a plurality of support rods 201 connected end-to-end in series. The first frame body 23 is arranged in the upper region of the device, and a guide rail 221 is arranged on the first frame body 23 so that the movement cooperation between the first cooperation mechanism 22 and the second cooperation mechanism 11 within the first frame body 23 can be limited to prevent the first cooperation mechanism 22 and the second cooperation mechanism 11 from influencing the movement of the filter device 1. The second frame body 24 is provided with a vent opening 200, wherein the plane in which the vent opening 200 is locatedmust be aligned with the air inlet 101. A sealing door 21 is arranged on the vent opening 200. When the sealing door 21 is in the evasive state, it ensures that the air inlet 101 is aligned with the vent opening 200 to facilitate filter operation on the production line. The combination of various frame bodies creates a stable support structure that simultaneously facilitates the repair and replacement of the filter device 1. This improves the structural strength and stability of the device, simplifies the maintenance process, and improves the availability and maintenance efficiency of the device.

[0041] It should be noted that the first frame body 23 and the second frame body 24 share a common first support rod, the first frame body 23 and the second frame body 24 being integrally formed by the first support rod, and the first sliding groove 261 being arranged on the first support rod. The second frame body 24 and the third frame body 25 share a common second support rod, the second frame body 24 and the third frame body 25 being integrally formed, and the second sliding groove 265 being arranged on the second support rod. In this way, the frame body 20 is integrally formed, which can improve the support of the filter device 1 and the reliability of the support frame 2.

[0042] Furthermore, the sealing door 21 comprises a plurality of plate bodies 210, wherein at least one of the plate bodies 210 is connected to the second frame body 24 via a connecting element 27, and two adjacent plate bodies 210 are connected via the connecting element 27. The sealing door 21 is divided into a plurality of plates 210 that are connected to one another. During the transition from the blocking state to the evasive state, the overall movement of the sealing door 21 is enabled by the connection of the plurality of plates 210, while simultaneously maintaining the stability and tightness of the structure. This improves the flexibility and adaptability of the device, makes it suitable for ventilation openings 200 of different sizes, and ensures the sealing performance of the device under various operating conditions.

[0043] As in the Fig. 1 and Fig. 3, in particular, the plurality of plate bodies 210 each comprise an active plate body 211 and a driven plate body 212, wherein one side of the active plate body 211 is connected to the second frame body 24 via the connecting element 27 and the other side of the active plate body 211 is connected to the driven plate body 212 via the connecting element 27, wherein the two opposite sides of the driven plate body 212 are each connected to the first sliding block 262 and the second sliding block 266, and a side of the active plate body 211 close to the driven plate body 212 is connected to the counter element 222 via the first tension element 223, wherein the active plate body 211 is provided for driving the driven plate body 212 in order to change the driven plate body from the locking state to the evasive state,and the driven plate body 212 is provided for driving the active plate body 211 to change the active plate body from the evasive state to the blocking state. The first tension element 223 is connected to the active plate body 211. Under the tensile force exerted by the first tension element 223, the active plate body 211 is moved relative to the second frame body 24 via the connecting element 27. In this case, the active plate body 211 drives the driven plate body 212. Since the other side of the driven plate body 212 is connected to the sliding block, the sliding block can ensurethat the active plate body 211 and the driven plate body 212 are moved along the width direction of the vent opening 200. The movements of the active plate body 211 and the driven plate body 212 are closely linked and form a coordinated closed-circuit system. When the filter device 1 begins to move, the active plate body 211 reacts first and then drives the driven plate body 212 via the connecting element 27 located between the active plate body and the driven plate body to follow the movement and thus achieve complete opening. After the exchange, the return mechanism 26 first returns the driven plate body 212 through the return action of the tension element and the sliding block, and then the active plate body 211 is returned via the driven plate body 212.This completes the automatic closing of the door panel. The movement is smooth and natural, effectively avoiding errors and inconveniences that may arise from manual operation.

[0044] In addition, the active plate body 211 is rotatably connected to the second frame body 24, and the active plate body 211 is rotatably connected to the driven plate body 212, wherein when the sealing door 21 changes from the blocking state to the evasive state, the active plate body 211 rotates about the second frame body 24 as the axis of rotation, so that an angle is included by the active plate body 210 and a plane in which the vent opening 200 is located, and the driven plate body 212 rotates about the connecting element 27 as the axis of rotation, so that the driven plate body 212 overlaps with the active plate body 211.Because the active plate body 211 is rotatably connected to the second frame body 24 and the active plate body 211 is rotatably connected to the driven plate body 212, when the active plate body 211 is pulled by the first pulling element 223, the active plate body 211 performs a circular movement around the second frame body 24 as the rotation axis, and the driven plate body 212 follows this circular movement. However, the other side of the driven plate body 212 is restricted in its linear movement along the sliding groove by the sliding block. As a result, during the transition of the sealing door 21 to the escape state, the active plate body 211 and the driven plate body 212 are finally supported in an overlapping manner on both sides of the vent opening 200. This reduces the space required by the sealing door 21 in the escape state and ensures the sealing performance of the device under various operating conditions.

[0045] Optionally, the connecting element 27 has a hinge structure, via which the active plate body 211 and the second frame body 24, as well as the active plate body 211 and the driven plate body 212, are hingedly connected to one another. In the deflection state of the sealing door 21, the active plate body 211 and the driven plate body 212 are mounted in an overlapping manner on both sides of the vent opening 200.

[0046] In one embodiment of the present application, as shown in the Fig.1 to 5, the number of first cooperation mechanisms 22, second cooperation mechanisms 11, return mechanisms 26, and sealing doors 21 is two each. Each half of the vent opening 200 is blocked by the two sealing doors 21, and is controlled by a set of first cooperation mechanisms 22, second cooperation mechanisms 11, and return mechanisms 26 to alternate between the blocking state and the escape state. Each of the sealing doors 21 includes an active plate body 211 and an aborted plate body 212. When the sealing door 21 is in the escape state, the active plate body 211 and the aborted plate body 212 are respectively supported on both sides of the vent opening 200.

[0047] The present application also provides a preferred embodiment of a hot-swappable dry filtration separator device, i.e., when a used dry filtration device is detached, its docking opening can be closed by mechanical locking, and when a new dry filtration device is installed, its docking opening can be opened by mechanical locking, thereby realizing a hot-swappable dry spray chamber filtration device replacement.

[0048] Specifically, the dry filtration separator comprises a support frame 2, an active plate body 211, a driven plate body 212, a first sliding groove 261, a first sliding block 262, a plurality of residual rollers, a second sliding groove 265, a second sliding block 266, a guide rail 221, a plumb line, a first tension member 223, a second tension member 263, an air inlet 101, an air outlet 102, a filter device 1, and a connecting member 27.

[0049] The support frame 2 has a structure in which profiles are welded into a body, thereby providing stable support for the entire dry filtration separation device. On each side of the support frame 2, there are a shaped steel and a support rod 201 as a pillar, with the shaped steel at the back and the support rod 201 at the front. At the bottom of the support frame 2, a support rod 201 is used to connect the shaped steel and the support rod 201. At the top of the support frame 2, two shaped steels are connected by a support rod 201, and in addition, a support rod 201 is used to connect the shaped steel and the top of the support rod 201, and two support rods 201 are arranged on the top to further connect the support rods 201 on both sides.

[0050] The active plate body 211 is connected to the frame body 20 via a hinge structure. There are two active plate bodies 211, one on each side. The active plate body 211 is a flat, rectangular, closed shell. The aborted plate body 212 is connected to the active plate body 211 via the hinge structure. There are two aborted plate bodies 212, one on each side. The aborted plate body 212 is a flat, rectangular, closed shell.

[0051] The first slide groove 261 is fixed to the frame body 20. There are two first slide grooves, one on each side. The cross-section of the first slide groove 261 is a long bar with a recess in the center. The first slide block 262 is installed to fit the first slide groove 261. A first slide block is installed in each of the first slide grooves 261. A plurality of fixed rollers are fixed to the support frame 2. The guide rail 221 is inclined and fixed between the two support rods 201 on the top of the support frame 2. There are two guide rails that are symmetrically distributed. The cross-section of the guide rail 221 is a C-shaped bar. The opening of the guide rail faces upward and the bottom of the guide rail is flush with the bottom of the support rod 201. The counter member 222 is installed to fit the guide rail 221. A counter member is installed on each rail.

[0052] The plumb line is suspended at the end of the second tension member 263, and the driven plate body 212 is connected to the plumb line by the second tension member 263, and the active plate body 211 is connected to the first sliding block 262 by the first tension member 223.

[0053] The filter device 1 is a movable component and comprises a housing 12. Two guide elements 111 are located on the top of the housing 12, and a roller is located on the bottom. An opening is located on one side of the housing, and there are two openings distributed over one another. The upper opening is the air inlet 101 of the filter device 1, and the lower opening is the air outlet 102 of the filter device. The air inlet 101 is connected to the vent 200, and the air outlet 102 is connected to the air outlet on the support frame 2.

[0054] The support frame 2 also includes several connecting elements. The first sliding block 262, the driven plate body 212, and the second tension element 263 are connected to each other by a connecting element. The connecting element is a structure with a round steel bar on a rectangular plate. The rectangular plate is fixed below the first sliding block 262, and the second tension element 263 is fixed to the round steel bar. The round steel bar passes through the hole of the eyelet plate on the driven plate body 212. The active plate body 211 and the first tension element 223 are connected to each other by another connecting element. The rectangular plate is fixed above the active plate body 211, and the first tension element 223 is fixed to the round steel bar.

[0055] The connecting elements 27 have a hinge structure for connecting the frame body 20 and the active plate body 211 as well as the active plate body 211 and the driven plate body 212, wherein there are twelve connecting elements 27 in total.

[0056] The active plate body 211 and the driven plate body 212 are connected to the frame body 20 and can then be opened and closed with the hinge structure. After opening, the active plate body 211 and the driven plate body 212 are folded and placed on both sides of the air inlet 101. At the same time, the active plate body 211 and the driven plate body 212 can be automatically opened and closed with the movement of the filter device 1 along a predetermined path.

[0057] The automatic opening process is as follows: On the filter device 1 near the vent opening 200, the counter element 222 is pressed by its upper guide element 111 to move it, which in turn drives the first tension element 223 to move and thus sets the active plate body 211 in a circular motion via the fixed rollers. During the circular motion, the active plate body 211 drives the driven plate body 212 to move. The movement of the driven plate body 212 is restricted by the lower second sliding groove 265 and the upper first sliding groove 261, so that the movement of its end portion is a linear movement. This ensures that after the active plate body 211 is opened, the driven plate body 212 can be folded together with the active plate body 211.

[0058] The automatic closing process proceeds as follows: Accordingly, when the filter device 1 moves away from the vent opening 200, the limiting effect of the upper guide element 111 on the counter element 222 disappears and the solder bypasses the connection of the fixed rollers with the driven plate body 212 via the second pulling element 263. The gravity of the solder pulls the driven plate body 212 so that it moves linearly along the first sliding groove 261, and the driven plate body 212 pulls the active plate body 211 so that it moves, thereby achieving automatic closing.

[0059] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: thanks to the avoidance of the vent hole 200 by the sealing door 21, it is convenient for the workers to maintain the filter device 1 or replace the filter components and materials in the filter device 1, so that the replacement of the filter material can be realized during operation.
