[0038] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0039] Reference below Figure 1-Figure 4 A battery slurry filtering device 100 according to an embodiment of the present invention is described. The battery slurry filtering device 100 is used to filter battery slurry.

[0040] like Figure 1As shown, the battery slurry filtration device 100 according to an embodiment of the present utility model includes: an inlet member 1, the inlet member 1 has an inlet member outlet 12; a plurality of iron removal members 2, the plurality of iron removal members 2 are connected in series to form a battery slurry flow channel 21, the battery slurry flow channel 21 has a flow channel inlet 211 and a flow channel outlet 212, the inlet member outlet 12 and the flow channel inlet 211 are connected, and the plurality of iron removal members 2 are configured to adsorb iron in the battery slurry when the battery slurry flows through the iron removal member 2.

[0041] The feed member 1 can be configured as a hopper, through which the battery slurry can flow into the battery slurry filtration device 100 for filtration. In some embodiments of the present application, the feed member 1 has two opposing ends along the height of the battery slurry filtration device 100. One end of the feed member 1 has an feed member outlet 12, and the other end of the feed member 1 has an feed member inlet. The battery slurry flows into the feed member 1 through the feed member inlet and flows out of the feed member 1 through the feed member outlet 12.

[0042] As some embodiments of the present application, the cross-sectional area of ​​the feed piece 1 gradually decreases along the direction from the feed inlet to the feed outlet 12. Such an arrangement can make the structural design of the feed piece 1 reasonable, which is conducive to the size of the feed inlet being larger than the feed outlet 12, so that the battery slurry can reliably flow into the feed piece 1 and reduce the risk of battery slurry spilling. Furthermore, the feed piece 1 can have a cover plate 13, and the material of the cover plate 13 can be, but is not limited to, metal, acrylic, glass, polytetrafluoroethylene, etc. When it is necessary to filter the battery slurry, the cover plate 13 is opened to open the feed inlet of the feed piece, so that the battery slurry can flow into the feed piece 1. When it is not necessary to filter the battery slurry, the cover plate 13 is closed to seal the feed inlet of the feed piece, thereby reducing the risk of impurities flowing into the feed piece 1.

[0043] There may be multiple iron removal parts 2. As some embodiments of the present application, two iron removal parts 2 may be provided. As some embodiments of the present application, three iron removal parts 2 may be provided. This application is illustrated by taking the case where two iron removal parts 2 are provided as an example. Such a setting can improve the working reliability of the iron removal parts 2, help reduce the iron content in the battery slurry, thereby improving the quality of the battery pole pieces, and further improving the performance and service life of the battery. It can also reduce the risk of increased costs of the battery slurry filtration device 100 due to an excessive number of iron removal parts 2.

[0044] A plurality of iron removal components 2 are connected in series to form a battery slurry flow channel 21. Along the battery slurry flow path in the battery slurry flow channel 21, the battery slurry flow channel 21 has a flow channel inlet 211 and a flow channel outlet 212. The feed member outlet 12 is connected to the flow channel inlet 211 so that the battery slurry can flow from the feed member 1 into the battery slurry flow channel 21 through the feed member outlet 12 and the flow channel inlet 211 in sequence. The battery slurry flows in the battery slurry flow channel 21. When the battery slurry flows through a plurality of iron removal components 2 in the battery slurry flow channel 21, the corresponding iron removal components 2 will absorb iron in the battery slurry to reduce the iron content in the battery slurry. After filtration, the battery slurry can flow out of the battery slurry flow channel 21 through the flow channel outlet 212, thereby achieving a filtering effect of the battery slurry.

[0045] Specifically, when it is necessary to filter the battery slurry, the cover plate 13 is opened to open the feed port of the feed piece, and the battery slurry is poured into the feed piece 1 from the feed port of the feed piece. No external power source is required. The battery slurry can flow naturally in the feed piece 1 under the action of gravity, and flows into the battery slurry flow channel 21 through the feed piece outlet 12 and the flow channel inlet 211 in turn. Under the action of gravity, the battery slurry can continue to flow in the battery slurry flow channel 21. When the battery slurry flows through multiple iron removal parts 2 in the battery slurry flow channel 21, the corresponding iron removal parts 2 will adsorb the iron in the battery slurry to reduce the iron content in the battery slurry. The filtered battery slurry can flow out of the battery slurry flow channel 21 through the flow channel outlet 212, thereby achieving the effect of filtering the battery slurry. When it is not necessary to filter the battery slurry, or after the battery slurry filtration is completed, the cover plate 13 is closed so that the cover plate 13 seals the feed port of the feed piece, thereby reducing the risk of impurities flowing into the feed piece 1.

[0046] Therefore, by setting up multiple iron removal members 2 in series to form a battery slurry flow channel 21, when the battery slurry flows in the battery slurry flow channel 21, the multiple iron removal members 2 can adsorb the iron in the battery slurry, so as to achieve the effect that the multiple iron removal members 2 can adsorb the battery slurry multiple times, so that the battery slurry passing through the battery slurry filtering device 100 meets the battery process requirements, which is beneficial to improving the quality of the battery electrode, and thus improving the performance and service life of the battery.

[0047] In some embodiments of the present invention, Figure 1 As shown, multiple iron removal parts 2 may include: a first iron removal part 22 and a second iron removal part 23, the first iron removal part 22 is formed with a first flow channel 221, the second iron removal part 23 is formed with a second flow channel 231, the first flow channel 221 and the second flow channel 231 are connected to form a battery slurry flow channel 21, and the first flow channel 221 is connected to the second flow channel 231 and the feed part outlet 12.

[0048] Among them, as some embodiments of the present application, the axis of the first iron removal member 22 can be perpendicular to the axis of the battery slurry flow channel 21, and the axis of the second iron removal member 23 can be parallel to the axis of the battery slurry flow channel 21. Further, the axis of the second iron removal member 23 can coincide with the axis of the battery slurry flow channel 21. As some embodiments of the present application, the axis of the first iron removal member 22 can be parallel to the axis of the battery slurry flow channel 21, and the axis of the second iron removal member 23 can be perpendicular to the axis of the battery slurry flow channel 21.

[0049] The first iron removal member 22 may be formed with a first flow channel 221. When the battery slurry flows through the first flow channel 221, the first iron removal member 22 may absorb the iron in the battery slurry. The second iron removal member 23 may be formed with a second flow channel 231. When the battery slurry flows through the second flow channel 231, the second iron removal member 23 may again absorb the iron in the battery slurry. The first flow channel 221 and the second flow channel 231 are connected to form a battery slurry flow channel 21. It should be noted that the inlet of the first flow channel 221 is configured as a flow channel inlet 211, and the outlet of the second flow channel 231 is configured as a flow channel outlet 212.

[0050] Along the battery slurry flow path in the battery slurry flow channel 21, the first flow channel 221 has two opposite ends, one end of the first flow channel 221 is connected to the feed outlet 12, and the other end of the first flow channel 221 is connected to the second flow channel 231, so that the first flow channel 221 is connected to the second flow channel 231 and the feed outlet 12.

[0051] Specifically, the battery slurry naturally flows into the first flow channel 221 through the feed and discharge port 12, and the first iron removal component 22 absorbs the iron in the battery slurry. After the first adsorption is completed, the battery slurry continues to flow into the second flow channel 231, and the second iron removal component 23 absorbs the iron in the battery slurry again, thereby achieving the effect that the first iron removal component 22 and the second iron removal component 23 can cooperate with each other. During the filtration process of the battery slurry, the iron in the battery slurry can be adsorbed for the second time, thereby further reducing the iron content in the battery slurry, and effectively improving the quality of the battery electrode.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first iron removal component 22 may include: a shell 222 and a first magnetic rod 223, a first installation space 224 is formed in the shell 222, the first installation space 224 is constructed as a first flow channel 221, the first magnetic rod 223 is arranged in the first flow channel 221, and the first magnetic rod 223 is perpendicular to the first flow channel 221.

[0053] Among them, a first installation space 224 can be formed in the shell 222, and the first installation space 224 can provide an installation position for the first magnetic bar 223. By installing the first magnetic bar 223 in the first installation space 224, the first magnetic bar 223 can be installed in the shell 222. The first installation space 224 can be configured as a first flow channel 221, and the battery slurry can flow in the first installation space 224. As some embodiments of the present application, along the height direction of the battery slurry filtering device 100, the cross-section of the shell 222 can be configured as a circle. When the first magnetic bar 223 is set to one, the cross-sectional shape of the shell 222 can be adapted to the shape of the peripheral wall of the first magnetic bar 223. When the first magnetic bar 223 is set to multiple, the multiple first magnetic bars 223 can be stably installed in the first installation space 224, thereby improving the structural stability of the first iron removal member 22.

[0054] When the battery slurry flows in the first flow channel 221, the battery slurry will flow through the first magnetic bar 223, so that the first magnetic bar 223 absorbs the iron in the battery slurry. By arranging the first magnetic bar 223 and the first flow channel 221 perpendicularly, the coverage area of ​​the first magnetic bar 223 on the first flow channel 221 can be increased, thereby reducing the risk of the battery slurry passing through the first flow channel 221 without flowing through the first magnetic bar 223, which is conducive to improving the adsorption effect of the first magnetic bar 223 on the iron in the battery slurry, thereby improving the iron removal effect of the first iron removal member 22.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, there are multiple first magnetic bars 223 , the multiple first magnetic bars 223 are parallel to each other, and a flow gap 225 is formed between any two adjacent first magnetic bars 223 .

[0056] The number of the first magnetic bars 223 may be, but is not limited to, two, three, seven or more. This application takes the number of the first magnetic bars 223 as an example for explanation. Figure 2 As shown, by providing seven first magnetic bars 223 and the seven first magnetic bars 223 being parallel to each other, the coverage area of ​​the first magnetic bars 223 on the first flow channel 221 can be further increased, and the risk of the battery slurry passing through the first flow channel 221 without flowing through the first magnetic bars 223 can be further reduced, thereby further improving the adsorption effect of the first magnetic bars 223 on iron in the battery slurry.

[0057] A flow gap 225 is formed between any two adjacent first magnetic bars 223 among the multiple first magnetic bars 223. That is, a flow gap 225 is formed between any two adjacent first magnetic bars 223 among the multiple first magnetic bars 223, so that the battery slurry can smoothly pass through the first flow channel 221 through the flow gap 225, reducing the risk of battery slurry clogging in the first flow channel 221. Furthermore, along the height direction of the battery slurry filtering device 100, the cross-section of the shell 222 can be constructed as a circle. Such a configuration can improve the arrangement effect of the first iron removal member 22, facilitate the shell 222 to reliably fix the multiple first magnetic bars 223, reduce the risk of relative position changes of the multiple first magnetic bars 223 in the shell 222, and further improve the structural stability of the first iron removal member 22.

[0058] In some embodiments of the present invention, Figure 3 As shown, the outer peripheral wall of each first magnetic bar 223 is formed with an annular groove 226 recessed toward the first magnetic bar 223 . The annular groove 226 extends along the circumference of the corresponding first magnetic bar 223 , and the peripheral walls of any two adjacent first magnetic bars 223 abut against each other.

[0059] An annular groove 226 is formed on the outer peripheral wall of each first magnetic bar 223. The annular groove 226 extends along the circumference of the corresponding first magnetic bar 223. In other words, the annular groove 226 is arranged around the outer peripheral wall of the first magnetic bar 223. Furthermore, at least one annular groove 226 can be provided. For example, the annular groove 226 can be provided as one, two, four, seven, or more annular grooves 226. This application uses seven annular grooves 226 as an example for description. By providing seven annular grooves 226, the battery slurry can flow through any of the seven annular grooves 226, thereby reducing the risk of battery slurry clogging in the first flow channel 221.

[0060] The annular groove 226 is recessed toward the inside of the first magnetic bars 223, and the peripheral walls of any two adjacent first magnetic bars 223 abut against each other, thereby forming a flow gap 225 between any two adjacent first magnetic bars 223. In some embodiments of the present application, the annular groove 226 is configured as the flow gap 225, so that the battery slurry can smoothly pass through the first flow channel 221 through the flow gap 225, reducing the risk of battery slurry clogging in the first flow channel 221.

[0061] It should be noted that, along the extension direction of the first magnetic bar 223, the first magnetic bar 223 has two opposite ends, one of which can have a hand-held handle 24. After the battery slurry filtration device 100 has been used for a period of time, the first magnetic bar 223 will absorb a large amount of iron, and the first iron removal member 22 is prone to clogging. The first magnetic bar 223 and the iron adsorbed by the first magnetic bar 223 can be pulled out of the housing 222 by pulling the hand-held handle 24, and a new first magnetic bar 223 can be assembled in the corresponding position, thereby achieving the effect of replacing the first magnetic bar 223. Furthermore, the metal surface of the hand-held handle 24 can be embossed with an anti-slip treatment process, thereby reducing the difficulty of replacing the first magnetic bar 223, and facilitating the cleaning of the replaced first magnetic bar 223 so that the first magnetic bar 223 can be reused.

[0062] In some embodiments of the present invention, Figure 1 As shown, the second iron removal component 23 may include: a discharge pipe 232 and a second magnetic rod 233, the discharge pipe 232 defines a second installation space 234, the second installation space 234 is constructed as a second flow channel 231, the second magnetic rod 233 is arranged in the second flow channel 231, and the second magnetic rod 233 and the second flow channel 231 are parallel.

[0063] Among them, the discharge pipe 232 can define a second installation space 234, and the second installation space 234 can provide an installation position for the second magnetic bar 233. By installing the second magnetic bar 233 in the second installation space 234, the second magnetic bar 233 can be installed in the discharge pipe 232. The second installation space 234 can be configured as a second flow channel 231, and the battery slurry can flow in the second installation space 234. As some embodiments of the present application, along the height direction of the battery slurry filtering device 100, the cross-section of the discharge pipe 232 can be configured as a circle. When the second magnetic bar 233 is provided as one, the cross-sectional shape of the discharge pipe 232 can be adapted to the shape of the peripheral wall of the second magnetic bar 233 to increase the coverage area of ​​the second magnetic bar 233 on the second flow channel 231, thereby facilitating the second magnetic bar 233 to reliably adsorb iron in the battery slurry.

[0064] When the battery slurry flows in the second flow channel 231, the battery slurry will flow through the second magnetic rod 233, so that the second magnetic rod 233 absorbs the iron in the battery slurry. By setting the cross-sectional shape of the discharge pipe 232 to be adapted to the peripheral wall shape of the second magnetic rod 233, and the second magnetic rod 233 being parallel to the second flow channel 231, the coverage area of ​​the second magnetic rod 233 on the second flow channel 231 can be increased, thereby reducing the risk of the battery slurry passing through the second flow channel 231 without flowing through the second magnetic rod 233, which is beneficial to improving the adsorption effect of the second magnetic rod 233 on the iron in the battery slurry, thereby improving the iron removal effect of the second iron removal component 23.

[0065] In some embodiments of the present invention, Figure 4 As shown, a groove 235 is formed on the outer peripheral wall of the second magnetic bar 233 , and the groove 235 extends along the axial direction of the second magnetic bar 233 .

[0066] Among them, the outer peripheral wall of the second magnetic bar 233 can be formed with a groove 235, and the groove 235 is recessed toward the second magnetic bar 233 to form a gap between the second magnetic bar 233 and the discharge pipe 232, which is conducive to the smooth passage of the battery slurry through the second flow channel 231 and reduces the risk of clogging of the battery slurry in the second flow channel 231. The groove 235 extends along the axial direction of the second magnetic bar 233, so that the extension direction of the groove 235 is consistent with the extension direction of the battery slurry in the second flow channel 231. The groove 235 can guide the battery slurry. Such a setting can make the arrangement of the groove 235 reasonable, which is conducive to the flow of the battery slurry along the groove 235, thereby reducing the risk of the second magnetic bar 233 blocking the battery slurry, and further reducing the risk of clogging of the battery slurry in the second flow channel 231.

[0067] Furthermore, the groove 235 can be set to at least one. This application takes the example of setting the groove 235 to seven. Such a setting can further facilitate the battery slurry to flow through the second iron removal component 23. By setting the groove 235 to seven, the contact area between the battery slurry and the second magnetic rod 233 can also be increased, thereby improving the iron removal effect of the second magnetic rod 233, which is beneficial for the second iron removal component 23 to better adsorb iron in the battery slurry.

[0068] It should be noted that, along the extension direction of the second magnetic bar 233, the second magnetic bar 233 has two opposite ends, one of which may also have a hand-held handle 24. After the battery slurry filtration device 100 has been used for a period of time, the second magnetic bar 233 will absorb a large amount of iron, and the second iron removal member 23 is prone to clogging. The second magnetic bar 233 and the iron adsorbed by the second magnetic bar 233 can be pulled out of the discharge pipe 232 simultaneously by pulling the hand-held handle 24, and a new second magnetic bar 233 can be assembled in the corresponding position, thereby achieving the effect of replacing the second magnetic bar 233. Furthermore, the metal surface of the hand-held handle 24 can be embossed with an anti-slip treatment process, thereby reducing the difficulty of replacing the second magnetic bar 233, and facilitating the cleaning of the replaced second magnetic bar 233 so that the second magnetic bar 233 can be reused.

[0069] In some embodiments of the present invention, Figure 1 As shown, the battery slurry filtering device 100 may further include: a filter element 3, the filter element 3 is located between the flow channel inlet 211 and the feed outlet 12, and the battery slurry flowing out of the feed outlet 12 flows to the flow channel inlet 211 through the filter element 3.

[0070] Wherein, as some embodiments of the present application, the filter element 3 may include a shell 31 and a filter element 32. As some embodiments of the present application, the filter element 3 may be constructed as a filter screen. As some embodiments of the present application, the filter element 3 may be assembled between the feed member 1 and the first iron removal member 22 through a quick-card structure, so that the filter element 3 is located between the flow channel inlet 211 and the feed member outlet 12. After the battery slurry enters the hopper, it can flow out from the feed member outlet 12, and the battery slurry is first filtered through the filter element 3 before flowing to the flow channel inlet 211, which is beneficial for the battery slurry to be fully filtered before iron removal, further reducing the clogging effect of the first iron removal member 22 and the second iron removal member 23.

[0071] It should be noted that after the battery slurry filtration device 100 has been used for a period of time, the filter element 3 may become clogged. In some embodiments of the present application, the quick-release mechanism can be removed, allowing the housing 31 and filter element 32 to be replaced as a whole. In some embodiments of the present application, the quick-release mechanism can be removed to open the housing 31, allowing the filter element 32 to be replaced separately. This allows for flexible placement of the filter element 3, allowing the battery slurry filtration device 100 to select the installation and removal method based on actual filtration needs.

[0072] The material of the filter element 3 can be, but is not limited to, a bladder filter element 32, a gauze, or a metal mesh material. The number of layers of the filter element 3 can be set to at least one layer. This application takes the number of layers of the filter element 3 as two layers as an example for explanation. By setting the number of layers of the filter element 3 to two layers, the filtering effect of the filter element 3 on impurities in the battery slurry can be improved, and the risk of increased production costs due to too many layers of the filter element 3 can be reduced.

[0073] In some embodiments of the present invention, Figure 1 As shown, the battery slurry filtering device 100 may further include: a handheld portion 4 , which is fixedly connected to the feed piece 1 .

[0074] Among them, when it is necessary to filter the battery slurry, the staff can hold the battery slurry filtering device 100 by grasping the handheld portion 4. The handheld portion 4 can be constructed of a metal material. Furthermore, the surface of the handheld portion 4 can be subjected to a metal surface embossing and anti-slip treatment process, which can reduce the risk of the battery slurry filtering device 100 falling off and being damaged when the staff grasps the handheld portion 4. As some embodiments of the present application, the handheld portion 4 and the feed piece 1 can be welded to each other so that the handheld portion 4 is fixedly connected to the feed piece 1. As some embodiments of the present application, the handheld portion 4 and the feed piece 1 can be connected by bolts so that the handheld portion 4 is fixedly connected to the feed piece 1. This application is illustrated by taking the welding connection between the handheld portion 4 and the feed piece 1 as an example. The welding connection can improve the connection reliability between the handheld portion 4 and the feed piece 1, reduce the risk of cracking or even disconnection between the handheld portion 4 and the feed piece 1, thereby improving the structural stability and safety of use of the battery slurry filtering device 100.

[0075] In some embodiments of the present invention, Figure 1 As shown, the battery slurry filtering device 100 may further include: a vacuum pumping component 5 , which is used to vacuum the most downstream iron removal component 2 along the battery slurry flow path in the battery slurry flow channel 21 .

[0076] Among them, as some embodiments of the present application, the vacuum member 5 can be constructed as a vacuum generator. During the filtration process of the battery slurry, the battery slurry will pass through the filter member 3 and multiple iron removal members 2 respectively. Due to the gap resistance, the battery slurry flows slowly by its own gravity. Along the battery slurry flow path in the battery slurry flow channel 21, by arranging a vacuum member 5, and the vacuum member is used to vacuum the most downstream iron removal member 2, a negative pressure can be generated at the most downstream iron removal member 2, and by using pressure to push the battery slurry, the flow speed of the battery slurry in the battery slurry flow channel 21 can be increased, thereby increasing the filtration speed of the battery slurry by the battery slurry filtering device 100. Furthermore, by using the vacuum member 5 to vacuum the most downstream iron removal member 2, it is also beneficial to eliminate bubbles in the filtered battery slurry, thereby improving the quality of the battery slurry.

[0077] In some embodiments of the present invention, Figure 1 As shown, the battery slurry filtering device 100 may further include an outflow port 6 and an outlet valve 7. After the battery slurry is filtered, the outlet valve 7 may be opened to open the outflow port 6, and the battery slurry may flow out of the battery slurry filtering device 100 from the outflow port 6, thereby facilitating the collection of the filtered battery slurry and facilitating the use of the filtered battery slurry in subsequent production.

[0078] As some embodiments of the present application, the weight of the battery slurry filtering device 100 can be limited to within 10 kg, and the total height of the battery slurry filtering device 100 can be limited to within 1 meter, so as to control the battery slurry filtering device 100 to a smaller volume. Such a setting can improve the operability of the battery slurry filtering device 100, which is beneficial for personnel to hold the battery slurry filtering device 100, thereby improving the convenience of use of the battery slurry filtering device 100, so that the battery slurry filtering device 100 can be used in laboratories or other small-batch filtration work scenarios, reducing the risk of most of the battery slurry adhering to the battery slurry filtering device 100 due to the battery slurry filtering device 100 being too large, thereby reducing the risk of too little battery slurry output in the battery slurry filtering device 100, and also helping to reduce the difficulty of maintenance of the battery slurry filtering device 100 by experimenters.
