[0002] Lithium-ion battery slurry preparation is a crucial process for manufacturing positive and negative electrode materials. It involves uniformly mixing active materials and additives through stirring and other methods to create a homogeneous paste. The slurry process improves the specific energy, electrochemical performance, and stability of the electrode materials, thereby enhancing the overall performance and cycle life of the lithium-ion battery. However, impurities and small particles that may remain after the lithium mixture preparation process often clog the steel mesh roller filter element used in the slurry process, affecting its performance. Therefore, regular cleaning and maintenance of the filter element are necessary to ensure its proper functioning.

[0003] Common cleaning methods include rinsing the surface with a high-pressure water gun and using ultrasonic technology, such as the ultrasonic cleaning method described in CN201110286129.X. However, this cleaning solution is mainly for cleaning sheet-shaped steel mesh. For cleaning drum-shaped filter elements, this device will cause uneven force on the surface of the filter element, resulting in ineffective cleaning. In addition, the specifications of steel mesh drum filter elements are not completely the same, the pore size of the filter screen is not completely the same, the density of the filter screen pores and the size of the dirt and impurities to be cleaned are different. The same ultrasonic frequency cannot take into account all working conditions, resulting in incomplete cleaning during use. After cleaning, the waste liquid contains a large number of dirt and dust particles. During the drainage process, the dirt and dust will stick to the surface of the filter element, affecting the cleaning effect.

[0004] In view of this, there is an urgent need to provide a lithium battery slurry filter cleaning device to solve the problem. Utility Model Content

[0005] To address at least one or more of the technical problems mentioned in the background section, this invention proposes a lithium battery slurry filter cleaning device.

[0019] Embodiments will now be described with reference to the accompanying drawings. It should be understood that, for the sake of simplicity and clarity, reference numerals may be repeated in the drawings to indicate corresponding or similar elements where deemed appropriate. Furthermore, numerous specific details are set forth in this invention to provide a thorough understanding of the embodiments described herein. However, those skilled in the art will understand that the embodiments described herein can be practiced without these specific details. In other instances, well-known methods, processes, and components have not been described in detail so as not to obscure the embodiments described herein. Moreover, this description should not be construed as limiting the scope of the embodiments described herein.

[0020] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, a lithium battery slurry filter element cleaning device is provided. It includes: a base plate 11, and a cover 12 sealed to the base plate 11. Multiple supports 13 are rotatably disposed above the base plate 11, the supports 13 being used to mount the filter element 10. It also includes a drive assembly for driving the supports 13 to rotate. A first spray assembly 14 is provided at the rotation center of the supports 13, and second spray assemblies 15 are provided inside opposite sides of the cover 12. When the filter element 10 is mounted on the supports 13, the first spray assembly 14 and the second spray assembly 15 respectively rinse the inside and outside of the filter element 10. Multiple sets of ultrasonic transducers 16 are provided on the outside of opposite sides of the cover 12.

[0021] When the cleaning device is in operation, the filter element 10 is mounted on the support 13 and rotates with the rotation of the support 13. Ultrasonic waves generated by the ultrasonic transducers 16 located on opposite sides of the housing 12 remove dirt adhering to the surface and mesh of the filter element 10. Simultaneously, the first spray assembly 14 and the second spray assembly 15 rinse the dirt. Because the filter element 10 mounted on the support 13 rotates continuously, the horizontal tangent at every point on the filter element 10 is perpendicular to the direction of ultrasonic wave propagation. This ensures that every point on the filter element 10 receives maximum exposure to the ultrasonic waves generated by the ultrasonic transducers 16, thereby improving the cleaning effect.

[0022] In one embodiment, each support 13 is fixedly connected to a rotating shaft 21, each rotating shaft 21 is fixedly connected to a bearing, each bearing is disposed in a bearing housing, each bearing housing is fixedly connected to the base plate 11, the rotating shaft 21 passes through the base plate 11 and extends to the underside of the base plate 11, and also includes a sealing ring for sealing the gap between the rotating shaft 21 and the base plate 11, the drive assembly drives the rotating shaft 21 located under the base plate 11 to rotate so that the support 13 rotates, and the sealing ring can prevent the cleaning liquid of the sealing cover 12 from flowing out when the rotating shaft 21 rotates relative to the base plate 11.

[0023] The rotation of the rotating shaft 21 can be achieved by setting a gear on the rotating shaft 21 extending below the base plate 11 and using a sprocket and chain transmission mechanism.

[0024] In another embodiment, each of the rotating shafts 21 has a hollow structure, and the first spray assembly 14 includes a cylindrical nozzle that passes through the hollow structure and extends upward to the outside of the rotating shaft 21. This allows the cylindrical nozzle of the first spray assembly 14 to be positioned inside the filter element 10 when the filter element 10 is mounted on the support 13, thus cleaning the interior of the filter element 10.

[0025] In another embodiment, the second spray assembly 15 includes square spray pipes horizontally arranged along the arrangement direction of the support 13, the square spray pipes being respectively arranged in the upper and middle parts of the housing 12. The square spray pipes arranged in the upper and middle parts of the housing 12 are used to rinse the dirt outside the filter element 10, and then, as the cleaning liquid flows downward along the outer surface of the filter element 10, it carries the dirt to the bottom plate 11, preventing the washed-off dirt from sticking to the surface and internal mesh of the filter element 10.

[0026] In some embodiments, the ultrasonic transducer 16 includes a low-frequency ultrasonic transducer and a high-frequency ultrasonic transducer, which are alternately arranged on opposite sides of the outer surface of the housing 12. The combined action of the two ultrasonic transducers, which can generate ultrasonic waves of different frequencies, can maximize the thorough cleaning of both large and small particles of dirt, further improving the cleaning effect.

[0027] To prevent the bottom of the filter element 10 from sticking with the dirt that has been washed away, in some other embodiments, when the filter element 10 is installed on the support 13, the bottom of the filter element 10 can be made not to contact the upper surface of the base plate 11, that is, the height of the filter element 10 relative to the upper surface of the base plate 11 is increased. At the same time, a drain hole can be provided on the base plate 11 to facilitate timely drainage of dirt during the cleaning process.
