In order to improve the quality of the product, a filter is often installed in the pipeline to filter the slurry passing through and remove impurities and other particles that may be carried in the slurry.

[0003] However, when replacing the filter screen, the pipeline needs to be disassembled to replace it, which is cumbersome and has low replacement efficiency. In addition, during the replacement process, the passage of the slurry must be stopped, which wastes time. Summary of the invention

When the filter structure needs to be replaced, it is only necessary to move or rotate the filter body to move the feed hole provided with the filter structure to be replaced to be connected with the first assembly hole, so that the filter structure can be replaced through the first assembly hole, and the feed hole provided with the filter structure to be replaced can be moved to be connected between the feed hole and the discharge hole. Through the above operation, the replacement demand for the filter structure can be met without disassembling the conveying pipeline, which is convenient for operation and conducive to improving the replacement efficiency. Moreover, while replacing the filter structure, the filter device can still operate normally to filter the slurry without suspending the operation, which is conducive to improving the filtering efficiency.

[0007] In some embodiments, one of the filter structure and the filter body is at least partially inserted into the other and is clipped to each other. In the above scheme, the filter structure can be detachably connected to the filter body by clipping, which is convenient for installation and removal, and is conducive to improving the replacement efficiency of the filter structure.

[0018] In some embodiments, the driving part extends out of the strip-shaped hole and protrudes from a side surface of the housing that is away from the accommodating cavity. This arrangement makes it easier for operators to control the driving part.

[0019] In some embodiments, the driving unit is movably connected to the filter body so that the driving unit can switch between a first position and a second position. In the first position, the driving unit restricts the movement of the filter body, and in the second position, the driving unit releases the restriction on the movement of the filter body. In the above solution, the driving unit can fix the position of the filter body so that the filter device will not be displaced during use, thereby improving the filtering efficiency and reliability of the filter device.

[0024] In some embodiments, the housing includes a first housing and a second housing connected to each other, the first housing and the second housing enclose a receiving cavity, the first housing includes a first wall, and the second housing includes a second wall. By providing the housing as a separate housing, it is helpful to reduce the difficulty of processing and facilitate the assembly of the filter body into the housing.

[0025] In some embodiments, the first housing and the second housing are detachably connected to each other, which makes it easier to replace or maintain the filter body.

[0026] In some embodiments, the filter device further includes a transfer tube, and at least one of the first wall and the second wall is connected to a transfer tube on a side facing away from the accommodating chamber, so that at least one of the feed hole and the discharge hole is connected to the transfer tube.

It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0055] The term "plurality" used in the present application refers to two or more (including two).

[0056] During the battery production process, slurry is transported to various processes in pipelines. In order to improve the quality of the product, a filter is often installed in the pipeline to filter the slurry passing through and remove impurities and other particles that may be carried in the slurry.

[0057] In the related art, a filter screen is usually fixed at the connection of a pipe using a clip for filtering. When replacing the filter screen, the pipe can only be removed for replacement, which is cumbersome and has low replacement efficiency. In addition, during the replacement process, the slurry cannot pass normally, delaying production time.

[0058] Based on the above technical problems, an embodiment of the present application provides a filtering device, which is arranged in a conveying pipeline, and the filtering device includes a shell and a filtering assembly. The shell is connected to the conveying pipeline, and the shell has a accommodating chamber and a first wall and a second wall opposite to each other along its thickness direction. The first wall has a feed hole, and the second wall has a discharge hole and a first assembly hole. At least one of the feed hole and the discharge hole is connected to the conveying pipeline. The filtering assembly is arranged in the accommodating chamber and includes a filtering body and a filtering structure. The filtering body has at least two feed holes distributed at intervals. The filtering structure is arranged in the feed hole and is detachably connected to the filtering body. Among them, the filtering body is movably connected to the shell along a direction intersecting with the thickness direction, so that the feed hole and the discharge hole are connected with any one of the feed holes along the thickness direction, and the first assembly hole is connected with any other feed hole along the thickness direction.

[0059] The slurry can enter the feed hole of the filter body from the feed hole, be filtered by the filter structure and then be discharged from the discharge hole, so that the filter device can meet the filtering demand for the slurry. When the filter structure needs to be replaced, it is only necessary to move the filter body to move the feed hole with the filter structure to be replaced to be connected to the first assembly hole, so as to replace the filter structure through the first assembly hole, and the feed hole with the filter structure to be replaced can be moved between the feed hole and the discharge hole. Through the above operation, the replacement demand can be met without disassembly, which is convenient for operation and conducive to improving the replacement efficiency. Moreover, while replacing the filter structure, the filter device can still operate normally to filter the slurry without suspending the operation, which is conducive to improving the filtering efficiency.

[0060] Please also read Figures 1 to 7 According to an embodiment of the present application, a filter device 100 is provided, which is arranged in a conveying pipeline 200. The filter device 100 includes a housing 10 and a filter assembly. The housing 10 is connected to the conveying pipeline 200. The housing 10 has a housing chamber 101 and a first wall 11 and a second wall 12 opposite to each other along its thickness direction X. The first wall 11 has a feed hole 111, and the second wall 12 has a discharge hole 121 and a first assembly hole 122. At least one of the feed hole 111 and the discharge hole 121 is connected to the conveying pipeline 200. The filter assembly is arranged in the housing chamber 101 and includes a filter body 20 and a filter structure 30. The filter body 20 has at least two feed holes 201 distributed at intervals. The filter structure 30 is arranged in the feed hole 201 and is detachably connected to the filter body 20. In which, the filter body 20 is movably connected to the outer shell 10 along a direction intersecting the thickness direction X, so that the feed hole 111 and the discharge hole 121 are connected with any one of the feed holes 201 along the thickness direction X, and the first assembly hole 122 is connected with any other one of the feed holes 201 along the thickness direction X.

[0061] The housing 10 is a component for forming the internal environment of the filter assembly, and the housing 101 formed by the housing 101 can accommodate the filter assembly. The housing 10 is also used to connect with the delivery pipeline 200 in the production equipment, so that the slurry can enter the filter device 100 from the delivery pipeline 200 to be filtered, or the slurry filtered by the filter device 100 can be output from the delivery pipeline 200.

[0062] The feed hole 111 and the discharge hole 121 are respectively connected to the accommodating cavity 101 . External slurry can enter the filter device 100 through the feed hole 111 , and can pass through the feed hole 201 to be filtered by the filter structure 30 . The filtered slurry can be discharged from the filter device 100 through the discharge hole 121 .

[0063] The filter structure 30 is used to filter and remove impurities from the slurry to ensure the cleanliness of the slurry. Particles such as impurities in the slurry may remain on the filter structure 30, and the filter structure 30 is detachably connected to the filter body 20 for easy replacement or maintenance.

[0064] “Active connection” means that the filter body 20 can be connected to the housing 10 in a direction intersecting the thickness direction X, and can be a rotational connection or a movable connection.

[0065] When the filter body 20 moves to a corresponding position relative to the outer shell 10, the feed hole 111 and the discharge hole 121 are connected with any one of the feed holes 201 along the thickness direction X. It can be understood that the feed hole 111, the feed hole 201 and the discharge hole 121 can form a filter channel, so that the slurry can pass through this filter channel to be filtered by the filter structure 30 in the filter channel, and the first assembly hole 122 is connected with any other feed hole 201 along the thickness direction X. It can be understood that there are also a feed hole 201 and a first assembly hole 122 outside the filter channel, and the filter structure 30 in the feed hole 201 can be replaced through the first assembly hole 122.

[0066] In the filter device 100 provided in some embodiments of the present application, the slurry can be filtered by the filter structure 30 through the feed hole 201. When the filter structure 30 needs to be replaced, it is only necessary to move or rotate the filter body 20 relative to the shell 10 to make the new feed hole 201 connected between the feed hole 111 and the discharge hole 121. The feed hole 201 that needs to be replaced is connected to the first assembly hole 122 to replace the filter structure 30 through the first assembly hole 122. Since the shell 10 is connected to the conveying pipeline 200, the filter structure 30 can be replaced without disassembling the conveying pipeline 200, which is easy to operate and is conducive to improving the replacement efficiency. In addition, during the replacement, the filter device 100 can still operate normally without suspending the operation, which is conducive to improving the filtering efficiency.

[0067] In addition, since there is no need to remove the conveying pipe 200 when replacing the filter structure 30, it can also prevent foreign matter from entering the conveying pipe 200 to contaminate the slurry. Therefore, the conveying pipe 200 equipped with the filter device 100 provided in the embodiment of the present application can also improve the cleanliness of the conveyed slurry, thereby helping to improve the production quality of the production equipment equipped with this filter device 100.

[0068] Optionally, the housing 10 may be but is not limited to being made of metal or non-metal materials. For example, the metal material may be copper, aluminum or stainless steel, etc.; the non-metal material may be polyethylene, polypropylene or polyvinyl chloride, etc.

[0069] The shape of the housing 10 can be determined according to the specific shape of the filter body 20 . For example, if the filter body 20 is a rectangular parallelepiped structure, a rectangular housing 10 can be selected; if the filter body 20 is a cylindrical structure, a cylindrical housing 10 can be selected.

[0070] Optionally, the filter assembly can be entirely disposed in the accommodating cavity 101, so that the outer shell 10 can better provide protection for the filter body 20 to prevent the filter body 20 from being bumped, contaminated, etc.; of course, the filter assembly can also be partially disposed in the accommodating cavity 101, and the other part extends out of the accommodating cavity 101.

[0071] The filter structure 30 and the filter body 20 may be detachably connected by fasteners, or may be detachably connected by snap-fitting or threaded fitting.

[0072] Optionally, the number of the feed holes 201 is set to two, which can satisfy the requirement that when the filter structure 30 in one of the feed holes 201 is replaced, the other feed hole 201 can also be connected between the feed hole 111 and the discharge hole 121 to meet the filtering effect on the slurry, and can also reduce the number of openings on the filter body 20 to reduce the impact on its structural strength, which is beneficial to extending the service life of the filter body 20, thereby helping to improve the reliability of the filter device 100.

[0073] See also Figure 5 and Figure 6 In some optional embodiments, the filter assembly further includes an adapter 50 and a fastener 40, a first portion of the adapter 50 abuts against a side of the filter body 20 along the thickness direction X toward the second wall 12, and another portion abuts against a side of the filter structure 30 along the thickness direction X toward the second wall 12, and the fastener 40 connects the adapter 50 and the filter body 20 along the thickness direction X.

[0074] The fastener 40 can connect the adapter 50 and the filter body 20 so that the filter structure 30 is limited in the feed hole 201 by the adapter 50. In the filter device 100 provided in some embodiments of the present application, the filter structure 30 can be detachably connected to the filter body 20 by using the fastener 40, which is convenient for installation and disassembly, and helps to improve operational efficiency.

[0075] Alternatively, the fastener 40 may include, but is not limited to, any one of a bolt, a screw, a stud, and the like.

[0076] Please continue reading Figure 5 and Figure 6In some optional embodiments, the filter body 20 has an assembly groove 202 connected to the feed hole 201 on one side of the filter body 20 along the thickness direction X toward the second wall 12, and the orthographic projection of the assembly groove 202 in the thickness direction X falls into the first assembly hole 122, and a portion of the adapter 50 is arranged in the assembly groove 202.

[0077] The orthographic projection of the assembly groove 202 in the thickness direction X falls into the first assembly hole 122 , which can be understood as the operator can pass the adapter 50 and the fastener 40 through the first assembly hole 122 to install or remove them to the assembly groove 202 .

[0078] The specific assembly process is as follows: first, the filter structure 30 can be placed in the feed hole 201, and then the adapter 50 is set in the assembly groove 202 and abutted against the filter structure 30, and finally, the fastener 40 is used to pass through the adapter 50 and the filter body 20 in sequence along the thickness direction X to connect the two, so that the filter structure 30 can be fixed in the feed hole 201; the specific disassembly process is as follows: first, the fastener 40 is disassembled, then the adapter 50 is disassembled, and finally the filter structure 30 is disassembled.

[0079] Please continue reading Figure 5 and Figure 6 In some optional embodiments, the first assembly hole 122 includes a main assembly hole 1221 and a sub-assembly hole 1222 that are connected to each other, the orthographic projection of the feed hole 201 in the thickness direction X falls into the main assembly hole 1221, and the orthographic projection of the assembly groove 202 in the thickness direction X falls into the sub-assembly hole 1222.

[0080] By configuring in the above manner, the filter structure 30, the fastener 40 and the adapter 50 can all pass through the first assembly hole 122 along the thickness direction X to be assembled and disassembled on the filter body 20, which is convenient for operation. In addition, by configuring the sub-assembly hole 1222, the area of ​​the opening on the first wall 11 can be reduced to reduce the impact on the structural strength of the first wall 11, thereby facilitating the improvement of the strength of the housing 10 and further improving the reliability of the filter device 100.

[0081] In some optional embodiments, the number of the assembly slots 202 and the adapter 50 are both set to at least two, and the assembly slots 202 and the adapter 50 are set one to one.

[0082] The assembly grooves 202 can be set to two, three, or even more, with at least two assembly grooves 202 distributed at intervals along the circumference of the feed hole 201. Correspondingly, the adapters 50 can be set to two, three, or even more, with at least two adapters 50 distributed at intervals along the circumference of the feed hole 201.

[0083] By configuring in the above manner, it is beneficial to improve the connection strength between the filter structure 30 and the filter body 20 to prevent the filter structure 30 from shaking, displacing or even detaching from the filter body 20 during use, so that the filter structure 30 is stable and reliable during use, and the slurry can be better filtered, which is beneficial to improve the reliability of the filter device 100.

[0084] Exemplarily, each feed hole 201 is connected to two symmetrically arranged assembly grooves 202, and each assembly groove 202 is correspondingly provided with an adapter 50. By arranging in this way, it is possible to improve the connection strength between the filter structure 30 and the filter body 20 while also helping to reduce costs.

[0085] Optionally, one adapter 50 may be provided with one fastener 40 , or may be provided with more than two fasteners 40 .

[0086] In some optional embodiments, a stopper or step structure is provided in the feed hole 201, and the filter structure 30 abuts against one side of the stopper or step structure along the thickness direction X toward the second wall 12 to facilitate assembly positioning of the filter structure 30 and provide support for the filter structure 30.

[0087] In some optional embodiments, the filter body 20 is rotatably connected to the housing 10 with the thickness direction X as the axial direction.

[0088] When a filter structure 30 is used up, a new filter structure 30 can be directly assembled in another feed hole 201. The newly installed filter structure 30 can be rotated between the feed hole 111 and the discharge hole 121 by rotating the filter body 20. The rotated filter structure 30 can be removed, cleaned and reused, so as to achieve the purpose of quick replacement.

[0089] The filter device 100 provided in some embodiments of the present application, by setting the filter body 20 to be rotatable, at least two feed holes 201 can be set at intervals along the circumference of the filter body 20, and the filter body 20 can change the position of the feed holes 201 by rotating, so that the second wall 21 only needs to be provided with one first assembly hole 122 to realize the replacement of the filter structure 30, which is beneficial to reducing the overall occupied space of the filter device 100, thereby helping to improve the space utilization rate of the filter device 100.

[0090] Please continue reading Figure 5 and Figure 6 In some optional embodiments, the filter device 100 includes a connecting shaft 60 extending along the thickness direction X, and the filter body 20 is rotatably connected to the housing 10 via the connecting shaft 60 .

[0091] The connection shaft 60 is provided to realize the rotation connection between the filter body 20 and the housing 10 , which has a simple structure and is easy to assemble.

[0092] Optionally, the number of the connecting shaft 60 may be set to one, and the connecting shaft 60 is passed through the filter body 20 to be connected with the first wall 11 and the second wall 12 .

[0093] In some optional embodiments, the filter body 20 has a rotation hole 203 that penetrates along the thickness direction X and is spaced apart from the material passing hole 201, and the connecting shaft 60 is passed through the rotation hole 203 and connected to the housing 10. This arrangement facilitates assembly.

[0094] The rotating hole 203 is disposed at the center of the filter body 20 .

[0095] Optionally, the connecting shaft 60 may be passed through the rotating hole 203 and loosely matched therewith, and one end of the connecting shaft 60 along the thickness direction X is fixedly connected to the first wall 11 , and the other end is fixedly connected to the second wall 12 .

[0096] Among them, the connecting shaft 60 can be fixedly connected to the side of the first wall 11 facing the accommodating cavity 101, or the first wall 11 can also be provided with a first through hole 113, and the connecting shaft 60 is passed through the first through hole 113 to be fixedly connected to the first wall 11; the connecting shaft 60 can be fixedly connected to the side of the second wall 12 facing the accommodating cavity 101, or the second wall 12 can also be provided with a second through hole 124, and the connecting shaft 60 is passed through the second through hole 124 to be fixedly connected to the second wall 12.

[0097] Optionally, the connecting shaft 60 may also be passed through the rotating hole 203 and fixedly connected to the filter body 20 , and one end of the connecting shaft 60 along the thickness direction X is rotatably connected to the first wall 11 , and the other end is rotatably connected to the second wall 12 .

[0098] Among them, the connecting shaft 60 can be rotatably connected to the side of the first wall 11 facing the accommodating cavity 101, or can also be passed through the first through hole 113 and loosely matched with it; the connecting shaft 60 can be rotatably connected to the side of the second wall 12 facing the accommodating cavity 101, or can also be passed through the second through hole 124 and loosely matched with it.

[0099] In other embodiments, the number of the connecting shafts 60 may also be set to two, wherein one connecting shaft 60 is connected between the first wall 11 and the filter body 20 , and the other connecting shaft 60 is connected between the second wall 12 and the filter body 20 .

[0100] In addition to the above-mentioned use of the connecting shaft 60 to achieve the rotational connection between the filter body 20 and the housing 10, the filter body 20 can be rotationally connected to the housing 10 through a pin, or the filter body 20 can also be rotationally connected to the housing 10 by means of a slider and a slide rail.

[0101] In addition to the above-mentioned rotational connection, in some embodiments, the filter body 20 can be movably connected to the housing 10 along a direction intersecting the thickness direction X. In this structure, the filter body 20 is sequentially provided with at least two material passing holes 201 along the moving direction.

[0102] For example, the filter body 20 can be connected to the housing 10 by being movable along the height direction of the housing 10. Under this structure, at least two first assembly holes 122 spaced apart along the height direction can be provided on the second wall 12, and the discharge hole 121 is provided between any two adjacent first assembly holes 122, and at least two feed holes 201 spaced apart along the height direction are provided on the filter body 20, and the filter body 20 can be moved up and down along the height direction to change the position of the feed hole 201.

[0103] See also Figure 1 In some optional embodiments, the shell 10 also has a strip hole 102 connected to the accommodating cavity 101, and the filter assembly also includes a driving part 70, which is arranged on a side surface of the filter body 20 facing the strip hole 102. The driving part 70 can move along the extension direction of the strip hole 102 to drive the filter body 20 to move relative to the shell 10.

[0104] “The extension direction of the strip hole 102” refers to the strip direction of the strip hole 102. For example, the strip hole 102 can be arranged on the side wall 13 connected between the first wall 11 and the second wall 12 and extend along the circumference of the outer shell 10. At this time, the extension direction of the strip hole 102 is the circumferential direction. For another example, the strip hole 102 can be arranged on the first wall 11 and / or the second wall 12 and extend along the direction of gravity. At this time, the extension direction of the strip hole 102 is the direction of gravity.

[0105] The filter device 100 provided in some embodiments of the present application is configured in the above manner, and an operator can use the driving unit 70 to drive the filter body 20 to move relative to the housing 10 to achieve replacement of the filter structure 30, which is easy to operate.

[0106] Optionally, the driving part 70 and the filter body 20 may be an integrated structure. Of course, the two may also be provided separately.

[0107] like Figure 5 As shown, in some optional embodiments, the driving portion 70 extends out of the bar-shaped hole 102 and protrudes from a side surface of the housing 10 facing away from the accommodating cavity 101 .

[0108] It can be understood that one end of the driving part 70 facing the filter body 20 is connected to the filter body 20 , and the other end extends out of the strip hole 102 and protrudes from a side surface of the housing 10 facing away from the accommodating cavity 101 .

[0109] The filter device 100 provided in some embodiments of the present application is configured in the above manner, which makes it easy for an operator to control the driving part 70 to drive the movement of the filter body 20 .

[0110] In other embodiments, the driving portion 70 is recessed in the surface of the filter body 20 in the direction from the filter body 20 to the strip-shaped hole 102 , so as not to interfere with other structures.

[0111] In some optional embodiments, the driving unit 70 is movably connected to the filter body 20 so that the driving unit 70 can switch between a first position and a second position. In the first position, the driving unit 70 limits the movement of the filter body 20. In the second position, the driving unit 70 releases the movement restriction on the filter body 20.

[0112] When the filter body 20 moves to the corresponding position, that is, it has a feed hole 201 connected between the feed hole 111 and the discharge hole 121, and has a feed hole 201 connected to the first assembly hole 122, the driving part 70 can be driven relative to the filter body 20 to make it in the first position to limit the movement of the filter body 20; when the filter structure 30 has a replacement requirement, that is, the position of the feed hole 201 needs to be changed, the driving part 70 is driven relative to the filter body 20 to make it in the second position, and the driving part 70 can release the movement restriction of the filter body 20, so that the filter body 20 can move relative to the outer shell 10 to adjust its position.

[0113] In some embodiments, the driving unit 70 can move or rotate relative to the filter body 20 in a certain direction so that it is engaged with the outer shell 10 to be in a first position to limit the movement of the filter body 20; the driving unit 70 can be driven to move or rotate relative to the filter body 20 in the opposite direction so that it is disengaged from the outer shell 10 to be in a second position to release the restriction on the movement of the filter body 20.

[0114] In some embodiments, the driving unit 70 can move or rotate relative to the filter body 20 in a certain direction so that it is engaged with the external component and is in a first position to limit the movement of the filter body 20; the driving unit 70 can be driven to move or rotate relative to the filter body 20 in the opposite direction so that it is disengaged from the external component and is in a second position to release the restriction on the movement of the filter body 20.

[0115] The filter device 100 provided in some embodiments of the present application is configured in the above manner, and the driving unit 70 can fix the position of the filter body 20 so that the filter device 100 will not be displaced during use, thereby improving the filtering efficiency and reliability of the filter device 100.

[0116] See also Figure 7 In some optional embodiments, the strip hole 102 includes a first hole 1021 and at least two second holes 1022 that are connected to and intersect with the first hole 1021, and the at least two second holes 1022 are spaced apart. The driving part 70 is movably connected to the filter body 20 along the extension direction of the second holes 1022. In the first position, the driving part 70 is engaged with any one of the second holes 1022. In the second position, the driving part 70 is disengaged from the second hole 1022.

[0117] “Intersecting arrangement” means that the extension direction of the first hole 1021 and the extension direction of the second hole 1022 intersect.

[0118] As an example, the number of the second holes 1022 may be two, and they are respectively disposed at two ends of the first hole 1021 .

[0119] That is to say, when any one of the feed holes 201 is connected between the feed hole 111 and the discharge hole 121, the drive unit 70 can move toward the second hole 1022 relative to the filter body 20 so that it is engaged with the second hole 1022 to limit the rotation of the filter body 20. At this time, there is still a feed hole 201 connected to the first assembly hole 122; the drive unit 70 can also move relative to the filter body 20 away from the second hole 1022 to disengage from the second hole 1022, thereby releasing the rotation restriction on the filter body 20.

[0120] The filtering device 100 provided in some embodiments of the present application is configured in the above manner, has a simple structure, and is easy to process.

[0121] See also Figure 1 and Figure 7 In some optional embodiments, the housing 10 further has a side wall 13 connected between the first wall 11 and the second wall 12, the first wall 11, the second wall 12 and the side wall 13 enclose a accommodating cavity 101, the side wall 13 has a strip hole 102, and the driving part 70 is arranged on the peripheral side of the filter body 20.

[0122] In the filter device 100 provided in some embodiments of the present application, at least one of the first wall 11 and the second wall 12 is connected to the delivery pipe 200, and the side wall 13 is provided with a strip hole 102. The above arrangement can avoid interference between the operator and the delivery pipe 200 when the filter body 20 is driven to move by the driving part 70. The layout is reasonable and easy to operate. In addition, the impact on the structural strength of the first wall 11 and the second wall 12 can be reduced to ensure the structural strength of the outer shell 10.

[0123] Exemplarily, the side wall 13 is provided with a first hole 1021 extending along the circumference of the housing 10, and is also provided with at least two second holes 1022 extending along the thickness direction X and communicating with the first hole 1021. One end of the driving part 70 in the radial direction is connected to the peripheral side of the filter body 20, and the other end extends from the strip hole 102 and protrudes from the side of the side wall 13 facing away from the accommodating cavity 101. The radial direction refers to the direction from the center of the filter body 20 to a certain point on the peripheral side of the filter body 20.

[0124] In some optional embodiments, the filter device 100 further includes a wear-resistant structure, and the surface of the filter body 20 facing the housing 10 is provided with the wear-resistant structure.

[0125] Specifically, a wear-resistant structure is provided on a surface of the peripheral side of the filter body 20 facing the side wall 13 .

[0126] In some optional embodiments, a surface of the housing 10 facing the filter body 20 is provided with a wear-resistant structure.

[0127] Specifically, a wear-resistant structure is provided on a surface of the side wall 13 facing the peripheral side of the filter body 20 .

[0128] It is understandable that when the filter body 20 moves relative to the outer shell 10, there may be a certain friction at the contact point between the two. Therefore, by providing a wear-resistant structure on the surface of the filter body 20 facing the outer shell 10 and / or the surface of the outer shell 10 facing the filter body 20, the friction between the filter body 20 and the outer shell 10 can be reduced when the filter body 20 moves, thereby reducing the possibility of particulate matter generated by friction, thereby avoiding the possibility of introducing foreign matter during the process of replacing the filter structure 30.

[0129] As an example, the filter body 20 and the housing 10 are both provided with wear-resistant structures on one side surface facing each other.

[0130] As an example, the peripheral side of the filter body 20 and the surface of one side of the side wall 13 facing each other are both provided with a wear-resistant structure.

[0131] Optionally, the wear-resistant structure can be set as rubber or sponge, and the rubber or sponge can be set on at least one of the filter structure 30 or the housing by bonding; the wear-resistant structure can also be set as a wear-resistant coating, which can effectively reduce wear and corrosion, and also has excellent lubrication properties, which can reduce friction to extend the service life of the filter device 100. The wear-resistant coating can be set on at least one of the filter structure 30 or the housing by chemical coating or thermal spraying. The wear-resistant coating can be made of a variety of materials, such as aluminum oxide, titanium oxide, tungstate, etc.

[0132] The wear-resistant structure of the filter device 100 provided in some embodiments of the present application can be made using any of the above, which is beneficial to improving the flexibility and applicability of the filter device 100.

[0133] like Figure 7 As shown, in some embodiments, the housing 10 includes a first shell 110 and a second shell 120 that are connected to each other. The first shell 110 and the second shell 120 enclose a receiving cavity 101 . The first shell 110 includes a first wall 11 , and the second shell 120 includes a second wall 12 .

[0134] By providing the housing 10 in a separately provided form, it is helpful to reduce the difficulty of processing and also convenient to assemble the filter body 20 into the housing 10 .

[0135] In some embodiments, the first shell 110 may further include a side wall 13 connected to the first wall 11 , that is, the first shell 110 is configured as a cylindrical structure, and the second shell 120 is configured as a plate-like structure.

[0136] In some embodiments, the second shell 120 may further include a side wall 13 connected to the first wall 11 , that is, the second shell 120 is configured as a cylindrical structure, and the first shell 110 is configured as a plate-like structure.

[0137] In some embodiments, the side wall 13 includes a third wall 131 connected to the first wall 11 , and a fourth wall 132 connected to the second wall 12 , and the first shell 110 and the second shell 120 are both configured as cylindrical structures.

[0138] like Figure 7 As shown, exemplarily, at least a portion of the third wall 131 is recessed along the thickness direction X toward the first wall 11 to form a first docking hole 1301, and at least a portion of the fourth wall 132 is recessed along the thickness direction X toward the second wall 12 to form a second docking hole 1302, and the first docking hole 1301 and the second docking hole 1302 together form a strip hole 102.

[0139] In some optional embodiments, the first shell 110 and the second shell 120 are detachably connected.

[0140] By configuring in the above manner, it is convenient to maintain or replace the filter body 20, thereby increasing the service life of the filter device 100 and reducing costs.

[0141] Optionally, the first shell 110 and the second shell 120 may be detachably connected by fasteners 40 such as bolts, screws, and studs.

[0142] Optionally, one of the first shell 110 and the second shell 120 is at least partially inserted into the other and snap-fitted to each other, or the first shell 110 and the second shell 120 may also be connected by welding or bonding.

[0143] See also Figures 5 to 7 In some embodiments, the first wall 11 further has a second assembly hole 112 connected to the accommodating cavity 101 , and in the thickness direction X, the orthographic projection of the second assembly hole 112 overlaps with the orthographic projection of the first assembly hole 122 .

[0144] The second assembly hole 112 is used to cooperate with the first assembly hole 122 to enable the filter structure 30 to be disassembled. For example, when disassembling the filter structure 30, the filter structure 30 can be pushed out of the feed hole 201 through the second assembly hole 112, so that the filter structure 30 can be disassembled from the first assembly hole 122, which is conducive to improving the disassembly efficiency.

[0145] Optionally, the second assembly hole 112 and the feed hole 111 are spaced apart from each other, which is beneficial to improving the strength of the first wall 11 and further to improving the structural strength of the housing 10 ; of course, the second assembly hole 112 and the feed hole 111 can also be holes connected as one.

[0146] Optionally, the first assembly hole 122 and the discharge hole 121 are spaced apart to improve the strength of the second wall 12 and further improve the structural strength of the housing 10 ; of course, the first assembly hole 122 and the discharge hole 121 may also be holes connected as one.

[0147] See also Figure 1 and Figure 2 In some optional embodiments, the filter device 100 also includes a transfer tube 80, and at least one of the first wall 11 and the second wall 12 is connected to the transfer tube 80 on the side facing away from the accommodating chamber 101, so that at least one of the feed hole 111 and the discharge hole 121 is connected to the transfer tube 80.

[0148] The filter device 100 is connected to the conveying pipeline 200 through a transfer tube 80. Specifically, the first wall 11 is connected to a transfer tube 80, which is connected to the feed hole 111, and the second wall 12 is connected to a transfer tube 80, which is connected to the discharge hole 121.

[0149] This arrangement facilitates the connection of the filter device 100 to other components via the adapter tube 80 .

[0150] like Figure 3 As shown, at least one of the first wall 11 and the second wall 12 may also be directly connected to the conveying pipe 200 .

[0151] Optionally, the first wall 11 can be connected to the conveying pipe 200, and the feed hole 111 is connected to the conveying pipe 200, the second wall 12 can be directly connected to an external device that receives the filtered slurry, and the discharge hole 121 is connected to this device, that is, the slurry can enter the feed hole 201 through the conveying pipe 200 and the feed hole 111, be filtered by the filtering structure 30 in the feed hole 201, and then flow out to the external device through the discharge hole 121.

[0152] Optionally, the second wall 12 can be connected to the conveying pipe 200, and the discharge hole 121 is connected to the conveying pipe 200. The first wall 11 can be directly connected to an external device having the slurry to be filtered, and the feed hole 111 is connected to this device. That is to say, the slurry in the external device can enter the feed hole 201 through the feed hole 111 to be filtered by the filtering structure 30 in the feed hole 201, and then flow out from the discharge hole 121 to the conveying pipe 200.

[0153] Optionally, the housing 10 and the delivery pipe 200 are detachably fixedly connected, which helps to improve the flexibility of use of the filtering device 100.

[0154] The filtering device 100 provided in the embodiment of the present application can be used to filter slurry, and can also be used to filter materials with other components. It is only necessary to replace the matching filtering structure 30 according to different products.

[0155] It can be understood that in the production process of the coating process, the slurry will pass through a filtration system composed of a multi-stage filter element and be transported along the delivery pipe 200 to the coating extrusion head. After the slurry passes through the coating filtration system, a certain number of particles will still enter the coating extrusion head with the slurry, and will eventually be blocked between the lip of the extrusion head and the coating back roller, causing production operation abnormalities such as particle scratches, dark marks, and scraping, which will affect the production quality of the membrane. Therefore, the filtration device 100 provided in the embodiment of the present application can be installed on the delivery pipe 200 that transports the slurry from the filtration system to the extrusion head in the coating process, which can not only further filter the slurry, but also facilitate disassembly without affecting production efficiency.

[0156] Optionally, the filter device 100 can be arranged on a side of a delivery pipe 200 for delivering slurry between the filter system and the extrusion head in the coating process, close to the extrusion head. The slurry in the embodiment of the present application can be cathode slurry or anode slurry.

[0157] In some optional embodiments, one of the filter structure 30 and the filter body 20 is at least partially inserted into the other and is snap-connected to each other.

[0158] One of the filter structure 30 and the filter body 20 is provided with a protrusion, and the other is provided with a slot.

[0159] Optionally, a convex portion is provided in the material passing hole 201 of the filter structure 30, and a slot matching the convex portion is provided on the side of the filter structure 30 facing the filter body 20, and the convex portion and the slot are snap-fitted to make the filter structure 30 and the filter body 20 detachably connected.

[0160] Optionally, a convex portion extending along the thickness direction X is provided in the feed hole 201 of the filter structure 30, and a groove recessed along the thickness direction X is provided on the side of the filter structure 30 facing the filter body 20, so that the filter structure 30 can be assembled into the feed hole 201 along the thickness direction X.

[0161] In the filter device 100 provided in some embodiments of the present application, the filter structure 30 can be detachably connected to the filter body 20 by snap-fitting, which is convenient for installation and disassembly and helps to improve the replacement efficiency of the filter structure 30.

[0162] In some optional embodiments, the inner circumference of the feed hole 201 is provided with a first threaded portion, the outer circumference of the filter structure 30 is provided with a second threaded portion, and the first threaded portion and the second threaded portion are threadably matched.

[0163] Specifically, the filter structure 30 can be screwed to be threadedly connected with the feed hole 201 .

[0164] In the filter device 100 provided in some embodiments of the present application, the filter structure 30 can be detachably connected to the filter body 20 by means of threaded engagement, which is convenient for installation and disassembly and helps to improve the replacement efficiency of the filter structure 30.

[0165] In the embodiment of the present application, the filter structure 30 may include a filter screen, which may be composed of a mesh or a fiber grid, occupying a small space and having a high filtering speed; the filter structure 30 may also include a filter element, which may be a hollow cylindrical or rectangular structure, which is conducive to improving the filtering effect; the filter structure 30 may also include a sponge, which has a porous structure and can absorb fine particles of magazines and has a good filtering effect. The filter structure 30 may select any of the above structures, which is conducive to improving the flexibility of use of the filter device 100.

[0166] In some optional embodiments, the orthographic projection of the outer shell 10 in the thickness direction X is a circular structure, so that the shapes of the outer shell 10 and the external delivery pipe 200 are adapted to each other, making the layout more reasonable, and the design of the circular outer shell 10 is not easy to interfere with external components, which is conducive to improving the versatility of the filtering device 100.

[0167] Optionally, the orthographic projection of the filter body 20 in the thickness direction X can be a circular structure so that it can adapt to the shape of the outer shell 10. Optionally, the orthographic projection of the filter structure 30 in the thickness direction X can be a circular structure so that it can adapt to the shape of the external delivery pipe 200, which is beneficial to improve the versatility of the filter device 100.

[0168] In other embodiments, the strip holes 102 can also be arranged on the first wall 11 and / or the second wall 12, and a driving part 70 is provided on at least one side of the filter body 20 along the thickness direction X. By arranging in this way, the first wall 11 and the second wall 12 are easy to process and form the strip holes 102, which is conducive to processing and manufacturing.

[0169] Optionally, the strip-shaped hole 102 may be a linear hole body, and of course, it may also be set as an arc-shaped hole body.

[0170] Optionally, in the thickness direction X, the orthographic projection of the feed hole 111 overlaps with the orthographic projection of the discharge hole 121. "Overlapping" means that the orthographic projection of the feed hole 111 in the thickness direction X and the orthographic projection of the discharge hole 121 in the thickness direction X have at least a partially overlapping area.

[0171] Exemplarily, in the thickness direction X, the orthographic projection of the feed hole 111 and the orthographic projection of the discharge hole 121 are arranged to overlap.

[0172] As an example, the feed hole 201 penetrates the filter body 20 along the thickness direction X, and the feed hole 111, the discharge hole 121 and the feed hole 201 located therebetween are coaxially arranged along the thickness direction X. "Coaxial arrangement" can be understood as that the centers of the feed hole 111, the discharge hole 121 and the feed hole 201 located therebetween are located on the same extension line.

[0173] The above arrangement facilitates the processing and manufacturing of the filter body 20 and can also reduce the space occupied by the feed hole 201 on the filter body 20, thereby reducing the space occupied by the filter body 20, and further helping to reduce the overall space occupied by the filter device 100, so as to improve the space utilization rate of the filter device 100.

[0174] Of course, in other embodiments, in the thickness direction X, the orthographic projection of the feed hole 111 may be staggered with the orthographic projection of the discharge hole 121. "Staggered" means that the orthographic projection of the feed hole 111 in the thickness direction X and the orthographic projection of the discharge hole 121 in the thickness direction X do not have an overlapping area. The height position of the feed hole 111 may be higher than the height position of the discharge hole 121, or may be lower than the height position of the discharge hole 121.

[0175] Optionally, the height position of the feed hole 111 is higher than the height position of the discharge hole 121, and the height position of the opening of the feed hole 201 toward the first wall 11 is higher than the height position of the opening toward the second wall 12, so that the slurry can move downward along the direction of gravity when passing through the filter device 100, which is beneficial to increase the speed of the slurry, thereby helping to improve the filtration efficiency of the filter device 100.

[0176] Please continue reading Figure 5 In some optional embodiments, the orthographic projection of the feed hole 201 connected to the first assembly hole 122 in the thickness direction X falls into the first assembly hole 122 .

[0177] By configuring in this manner, the filter structure 30 can pass through the first assembly hole 122 along the thickness direction X to be assembled into the feed hole 201, or be removed from the first assembly hole 122 along the thickness direction X, which facilitates the assembly and disassembly of the filter structure 30, thereby improving the replacement efficiency of the filter structure 30 and facilitating operation.

[0178] In other embodiments, the orthographic projection of the first assembly hole 122 in the thickness direction X falls into the feed hole 201 connected thereto, and the circumferential sides of both the filter body 20 and the outer shell 10 are provided with connected through holes.
