[0048] In addition, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more features. In the description of the present application, unless otherwise stated, the meaning of "multiple" is two or more.

[0049] As shown in the background, in the prior art, the filter includes a cylinder and a filter structure arranged in the cylinder, the filter structure includes a skeleton and a filter screen, the filter screen is connected to the outside of the skeleton by a plurality of screws. The cylinder is provided with an inlet and an outlet, and the slurry enters the cylinder through the inlet, and then passes through the filter screen and the skeleton from the outside to the inside, and is discharged from the outlet. Due to the bridging phenomenon in the filtering process, the pressure of the filter increases after bridging, the aperture of the filter screen is enlarged under pressure, which easily leads to deformation and damage of the aperture, therefore, the filter screen needs to be replaced frequently.

[0050] However, the existing filter needs to disassemble a plurality of screws in sequence to remove the old filter screen when replacing the filter screen, and then install a new filter screen, and then reinstall a plurality of screws during installation, which is complicated and low in replacement efficiency.

[0051] Based on this, the filtering device and the filtering system provided by the application, the filtering device is provided with a filtering assembly, a support and a shell, the filtering assembly includes a support member and a filter screen, the filter screen is sleeved on the support member. The support is arranged at the first end of the support member, the support has a discharge port and a plurality of locking members, the locking members are rotatably arranged on the support, and the locking members collectively clamp the filter screen and the support member. The shell is detachably connected to the support, the shell is provided with an inlet and a containing cavity in communication with the inlet, the filter screen and the support are located in the containing cavity, and the slurry to be filtered can enter the containing cavity through the inlet and be filtered through the filter screen in the containing cavity. Since the discharge port is located in the area surrounded by the filter screen and is in communication with the filter holes on the filter screen, the slurry filtered through the filter screen can be discharged from the discharge port. When replacing the filter screen, the shell can be first detached from the support, and then the locking members are rotated along their own axes relative to the support, so that the locking members release the filter screen and the support member, so that the filter screen can be replaced. After the filter screen is replaced, the locking members are rotated again, so that the locking members collectively clamp the replaced filter screen and the support member. The filtering device and the filtering system provided by the application are convenient for replacing the filter screen, easy to operate, and improve the replacement efficiency.

[0052] In order to make the purpose, technical scheme and advantages of the application clearer, the technical scheme in the embodiments of the application will be described in more detail below with reference to the drawings in the preferred embodiments of the application. In the drawings, the same or similar reference signs represent the same or similar components or components with the same or similar functions throughout. The described embodiments are part of the embodiments of the application, not all embodiments. The embodiments described below by reference to the drawings are exemplary and are intended to explain the application, and cannot be understood as limiting the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the application.

[0053] Referring to Figures 1 to 5 The filtering device provided by the application includes a filtering assembly 100, a support 200 and a shell 300, the filtering assembly 100 includes a support member 110 and a filter screen 120, and the filter screen 120 is sleeved on the support member 110.

[0054] The support 200 is arranged at the first end 112 of the support member 110, and the support 200 has a discharge port 210 and a plurality of locking members 220. The discharge port 210 is located in the area surrounded by the filter screen 120 and is in communication with the filter holes on the filter screen 120, and the locking members 220 are rotatably arranged on the support 200.

[0055] The locking members 220 are configured to rotate along their own axes relative to the support 200 to collectively clamp or release the filter screen 120 and the support member 110.

[0056] The shell 300 is detachably connected to the support 200, and the shell 300 is provided with a feeding port 311 and a containing cavity 320 communicating with the feeding port 311. The filter screen 120 and the support 110 are both located in the containing cavity 320.

[0057] The filter assembly 100 is provided with the filter screen 120 and the support 110. The support 110 provides support for the filter screen 120. The filter screen 120 is used to filter metal impurities, particles and bubbles in the slurry, so as to improve the purity of the slurry and the quality of the pole piece. The support 110 provides structural support for the filter screen 120, which can reduce the possibility of deformation or damage of the filter screen 120 during use.

[0058] Specifically, the containing cavity 320 is arranged in the shell 300 to provide a containing space for the filter screen 120 and the support 110. The feeding port 311 is arranged on the shell 300 and communicates with the containing cavity 320. The slurry to be filtered can enter the containing cavity 320 through the feeding port 311.

[0059] Since the filter screen 120 and the support 110 are both located in the containing cavity 320, the slurry entering the containing cavity 320 can be filtered by the filter screen 120 in the containing cavity 320.

[0060] In addition, the support 200 is arranged at one end of the support 110, and the discharge port 210 is arranged on the support 200 and located in the area surrounded by the filter screen 120 and communicates with the filter holes on the filter screen 120. Therefore, the filtered slurry can be discharged through the discharge port 210 on the support 200.

[0061] The filter screen 120 is sleeved on the support 110. Exemplarily, the filter screen 120 and the support 110 can both be conical, or can both be cylindrical, or can have other shapes, and the embodiments of the present application do not make too many limitations in this regard.

[0062] In specific implementation, the support 110 can be made of a corrosion-resistant and high-strength material, such as stainless steel or high-strength plastic, to ensure stability in high pressure and chemical environment, so that it can withstand the pressure generated during the filtering process and provide sufficient support force for the filter screen 120.

[0063] The filter screen 120 can select filter holes with appropriate pore size according to the characteristics of the slurry to ensure effective filtration of impurities without affecting the flow of the slurry.

[0064] Exemplarily, the filter screen 120 can be made of a wear-resistant and chemical corrosion-resistant material, such as a polymer or a metal mesh, or can be made of other materials, and the embodiments of the present application do not make too many limitations in this regard.

[0065] It should be noted that multiple locking elements 220 are provided on the support 200. The locking elements 220 are rotatably mounted on the support 200. Each locking element 220 clamps the filter screen 120 and the support member 110 together, which can fix the filter screen 120 and prevent the filter screen 120 from falling off or shifting.

[0066] When the filter 120 needs to be replaced, the housing 300 can be detached from the support 200 first. Then, the locking members 220 can be rotated relative to the support 200 along their own axis to release the filter 120 and the support member 110. This allows the old filter 120, which is fitted onto the support member 110, to be removed, and the new filter 120 to be fitted onto the support member 110. Next, the locking members 220 are rotated further so that they collectively clamp the filter 120 and the support member 110. Finally, the housing 300 is connected to the support 200, thus realizing the replacement of the filter 120. This operation is convenient and improves replacement efficiency.

[0067] The housing 300 is detachably connected to the support 200. For example, the housing 300 and the support 200 can be connected by a snap fastener, a clamp, or other means. This application embodiment does not impose too many restrictions on this.

[0068] Understandably, compared to the inconvenience of replacing the filter screen 120 in existing filters, the filtration device provided in this application embodiment, by setting up a filter assembly 100, a support 200, and a housing 300, includes a support member 110 and a filter screen 120, with the filter screen 120 sleeved on the support member 110. The support 200 is located at the first end 112 of the support member 110, and has a discharge port 210 and multiple locking members 220. The locking members 220 are rotatably mounted on the support 200, and all locking members 220 together clamp the filter screen 120 and the support member 110. The housing 300 is detachably connected to the support 200. The housing 300 has an inlet 311 and a receiving cavity 320 communicating with the inlet 311. The filter screen 120 and the support member 110 are both located within the receiving cavity 320. The slurry to be filtered can enter the receiving cavity 320 through the inlet 311 and be filtered by the filter screen 120 within the receiving cavity 320. Since the outlet 210 is located within the area enclosed by the filter screen 120 and communicates with the filter holes on the filter screen 120, the slurry filtered by the filter screen 120 can be discharged through the outlet 210. When replacing the filter screen 120, the housing 300 can be detached from the support 200 first, and then the locking member 220 can be rotated relative to the support 200 along its own axis to release the filter screen 120 and the support member 110, thereby allowing the filter screen 120 to be replaced. After the filter screen 120 is replaced, the locking member 220 is rotated so that all locking members 220 together clamp the replaced filter screen 120 and the support member 110. The filtration device provided in this application facilitates the replacement of the filter screen 120, is easy to operate, and improves the replacement efficiency.

[0069] In some embodiments, refer to Figure 2 and Figure 4 As shown, the locking member 220 includes a locking part 221 and a first connecting part 222. The locking part 221 is rotatably connected to the support 200 through the first connecting part 222. Each locking part 221 together clamps or releases the filter screen 120 and the support member 110.

[0070] Understandably, the locking part 221 is rotatably connected to the support 200 through the first connecting part 222, and the clamping or releasing of the filter screen 120 and the support 110 can be achieved through a simple rotation action, which is convenient to operate and improves the replacement efficiency.

[0071] For example, the first connecting part 222 can be a connecting shaft, and the locking part 221 can be provided with a connecting hole. One end of the connecting shaft is connected to the support 200, and the other end of the connecting shaft is inserted into the connecting hole, so that the locking part 221 can rotate relative to the connecting shaft.

[0072] In some embodiments, refer to Figure 2 and Figure 4As shown, the locking part 221 has a first state and a second state. When the locking part 221 is in the first state, the locking part 221 abuts against the filter screen 120; when the locking part 221 is in the second state, the locking part 221 disengages from the filter screen 120.

[0073] Understandably, by rotating the locking part 221, the locking part 221 can switch between a first state and a second state, thereby clamping or releasing the filter screen 120 and the support member 110. Specifically, when each locking part 221 is rotated to the first state (not shown in the figures), the locking part 221 abuts against the filter screen 120, thereby clamping the filter screen 120 and the support member 110 together. When each locking part 221 is rotated to the second state (refer to...), the locking part 221 abuts against the filter screen 120, thereby clamping the filter screen 120 and the support member 110 together. Figure 3 As shown), the locking part 221 disengages from the filter screen 120, thereby releasing the filter screen 120 and the support member 110.

[0074] In some embodiments, refer to Figure 4 As shown, the locking part 221 is in the shape of a ring.

[0075] It should be noted that when each locking part 221 is in the first state, the edge of each ring abuts against the filter screen 120, thereby the locking parts 221 together clamp the filter screen 120 and the support member 110. When each locking part 221 is in the second state, the edge of each ring disengages from the filter screen 120, thereby the locking parts 221 release the filter screen 120 and the support member 110.

[0076] It should also be noted that the annular locking part 221 has smooth edges, which can prevent the locking part 221 from damaging the filter screen 120. In addition, the annular locking part 221 has a circular hole in the middle, which facilitates driving its rotation and makes operation convenient.

[0077] In some embodiments, refer to Figure 4 As shown, the locking member 220 also includes a second connecting part 223, which is connected to the support 200. The first connecting part 222 is rotatably connected to the second connecting part 223, and the rotation axis of the first connecting part 222 is perpendicular to the rotation axis of the locking part 221.

[0078] Specifically, the first connecting part 222 is rotatably connected to the support 200 by providing a second connecting part 223. The first connecting part 222 can rotate relative to the second connecting part 223 within a certain range. The first connecting part 222 can drive the locking part 221 to move synchronously. Since the rotation axis of the first connecting part 222 is perpendicular to the rotation axis of the locking part 221, the first connecting part 222 can adjust the position of the locking part 221 to change the distance between the locking part 221 and the filter screen 120. Thus, the locking part 220 can more easily clamp or release the filter screen 120 and the support 110.

[0079] For example, the second connecting part 223 can be bolted to the support 200, and a collar can be provided on the first connecting part 222. The first connecting part 222 is sleeved on the second connecting part 223 through the collar. The first connecting part 222 can not only rotate relative to the second connecting part 223 and the support 200, but also can move along the extension direction of the second connecting part 223.

[0080] In some embodiments, refer to Figure 2 and Figure 5 As shown, the filtration device also includes a first fixing member 400, and a support member 110 is provided with an abutment portion 113. The first fixing member 400 is sleeved on the filter screen 120 and the support member 110. The filter screen 120 is clamped between the first fixing member 400 and the support member 110, and the first fixing member 400 abuts against the abutment portion 113.

[0081] It should be noted that the first fixing member 400 is sleeved on the filter screen 120 and the support member 110, and the first fixing member 400 abuts against the abutting part 113 on the support member 110, so that the filter screen 120 is firmly fixed between the first fixing member 400 and the support member 110, so that the filter screen 120 and the support member 110 remain stable during use and reduce the possibility of displacement of the filter screen 120.

[0082] In some embodiments, refer to Figure 2 , Figure 4 and Figure 5 As shown, the abutting part 113 has a plurality of first grooves 1131, the first fixing member 400 has a plurality of second grooves 410, the first grooves 1131 and the second grooves 410 are connected, and each first connecting part 222 is sequentially inserted into the first groove 1131 and the second groove 410, and the locking part 221 abuts against the first fixing member 400.

[0083] Understandably, by setting the first groove 1131 and the second groove 410, the first groove 1131 and the second groove 410 provide an insertion position for the first connecting part 222, which can provide additional mechanical support and stability to fix the first connecting part 222 to the support member 110 and the first fixing member 400. The locking part 221 abuts against the first fixing member 400, and the first fixing member 400 can limit the locking part 221, prevent the locking part 221 from rotating automatically, improve the reliability and stability of the locking part 221, and prevent the filter screen 120 from loosening and shifting.

[0084] In some embodiments, refer to Figure 2 and Figure 3As shown, the filtration device also includes a second fixing member 500, which is connected to the second end 114 of the support member 110. At least a portion of the filter screen 120 is located within the second fixing member 500 to fix the filter screen 120 to the support member 110.

[0085] Specifically, a second fastener 500 is connected to the second end 114 of the support member 110. The second fastener 500 provides a fixing function for the filter screen 120 and the support member 110, so that the filter screen 120 remains stable during the filtration process and prevents displacement or loosening due to fluid pressure or vibration.

[0086] In some embodiments, refer to Figure 2 and Figure 3 As shown, the filtration device also includes a connector 600, which connects the second fixing member 500 and the support member 110.

[0087] It should be noted that the second fixing member 500 is connected to the support member 110 via the connector 600, which improves the connection strength, prevents the second fixing member 500 from detaching from the support member 110, and improves the reliability of the device. Exemplarily, the connector 600 can be a screw or bolt, or other connection structures; this application embodiment does not impose excessive limitations on this.

[0088] In some embodiments, refer to Figure 3 and Figure 5 As shown, the second fixing member 500 has a through hole 510, one of the connecting member 600 and the support member 110 has an external thread 610, and the other has an internal thread 115 that matches the external thread 610. The external thread 610 is connected to the internal thread 115 through the through hole 510.

[0089] Understandably, threaded connections provide a reliable and robust connection method, capable of withstanding significant mechanical stress and vibration, ensuring a secure connection between the second fastener 500 and the support 110. Threaded connections also possess self-locking properties, effectively preventing loosening during operation due to vibration or other external forces.

[0090] For example, refer to Figure 3 and Figure 5 As shown, an external threaded portion 610 can be provided on the connector 600, and a matching internal threaded portion 115 can be provided on the support 110; alternatively, a threaded portion can be provided on the support 110, and a matching internal threaded portion 115 can be provided on the connector 600 (not shown in the figure). This application embodiment does not impose too many restrictions on this.

[0091] In some embodiments, refer to Figure 2 As shown, the dimensions of the support member 110 increase sequentially from the second end 114 to the first end 112.

[0092] It should be noted that since the support 200 is located at the first end 112 of the support member 110, the outlet 210 on the support 200 is connected to the filter hole, that is, the filtered slurry flows out from the first end 112. The gradually expanding design helps to guide the fluid to flow naturally to a wider area, reduce flow resistance, thereby promoting the outflow of slurry and improving filtration efficiency.

[0093] In some embodiments, refer to Figure 2 and Figure 5 As shown, the support member 110 has multiple flow holes 111. The diameter of the flow holes 111 is larger than that of the filter holes. The flow holes 111 connect the filter holes and the discharge port 210.

[0094] Understandably, the diameter of the flow hole 111 is larger than that of the filter hole, which means that the filtered slurry can pass through the support 110 more quickly, reducing the residence time of the slurry in the device and improving the overall flow efficiency.

[0095] In practical implementation, the position and number of flow holes 111 can be reasonably distributed according to the principles of fluid dynamics to optimize the fluid flow path and filtration performance.

[0096] In some embodiments, refer to Figure 3 As shown, a cover plate 310 is provided on the housing 300. The cover plate 310 is detachably connected to the housing 300, and the feed port 311 is provided on the cover plate 310.

[0097] It should be noted that the removable cover 310 design makes cleaning and maintenance of the interior of the housing 300 more convenient. Operators can easily remove the cover 310 to directly access the internal structure for cleaning and inspection.

[0098] For example, the cover plate 310 can be connected to the housing 300 by a snap fastener, a clamp, or other means. This application embodiment does not impose too many restrictions on this.

[0099] In some embodiments, refer to Figure 3 As shown, the cover plate 310 is also provided with a discharge port 312, which is connected to the receiving cavity 320.

[0100] By setting a discharge port 312 on the cover plate 310, metal impurities and particles intercepted by the filter screen 120 can be discharged through the discharge port 312, making the discharge process more direct and convenient, eliminating the need for additional discharge pipes and reducing the complexity of the system.

[0101] In practice, the size and position of the discharge port 312 can be set according to different slurry characteristics and operational requirements to ensure smooth discharge.

[0102] In some embodiments, refer to Figure 2 As shown, the filter device also includes at least one seal 700, which is disposed between the support 200 and the housing 300.

[0103] Understandably, by providing the seal 700, the sealing performance of the device can be improved, effectively preventing leakage of slurry or other fluids from the gap between the support 200 and the housing 300, thereby improving the reliability of the device. In a specific implementation, the seal 700 can also be provided between the housing 300 and the cover plate 310 to improve the sealing performance between the housing 300 and the cover plate 310.

[0104] It should be noted that, depending on the operating environment and fluid characteristics, corrosion-resistant, high-temperature-resistant, and wear-resistant sealing materials, such as rubber, silicone, or polytetrafluoroethylene, can be selected.

[0105] This application also provides a filtration system, including a system body and a filtration device disposed on the system body.

[0106] The specific structure and operation of the filtration device have been described in detail in the above embodiments, and will not be repeated here.

[0107] Those skilled in the art will understand that the filtration device and system provided in this application comprise a filtration assembly, a support, and a housing. The filtration assembly includes a support member and a filter screen, with the filter screen fitted onto the support member. The support member is located at the first end of the support member and has an outlet and multiple locking members. The locking members are rotatably mounted on the support member and collectively clamp the filter screen and the support member. The housing is detachably connected to the support member and has an inlet and a receiving cavity communicating with the inlet. The filter screen and the support member are both located within the receiving cavity. The slurry to be filtered can enter the receiving cavity through the inlet and be filtered by the filter screen within the receiving cavity. Since the outlet is located within the area enclosed by the filter screen and communicates with the filter holes on the filter screen, the slurry filtered by the filter screen can be discharged through the outlet. When replacing the filter screen, the housing can be detached from the support member first, and then the locking members can be rotated relative to the support member along their own axes to release the filter screen and the support member, thereby allowing the filter screen to be replaced. After replacing the filter screen, rotate the locking mechanism to clamp the replaced filter screen and support component together. The filtration device and system provided in this application facilitate filter screen replacement, are easy to operate, and improve replacement efficiency.
