Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery slurry filtration technology, and in particular to a lithium-ion battery slurry filtration device. Background Technology

[0002] Currently, lithium-ion battery production requires filtering slurry to remove impurities. However, existing filtration devices are not easy to clean after filtration. Therefore, a lithium-ion battery slurry filtration device is proposed. Utility Model Content

[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides a lithium-ion battery slurry filtration device, comprising: a filter tank, an inlet pipe integrally connected to the top of the filter tank, an outlet pipe integrally connected to the bottom of the filter tank, a plurality of mounting slots sequentially opened from top to bottom in the middle of the filter tank, a plurality of bearing rings corresponding one-to-one with the mounting slots integrally connected to the inner wall of the filter tank, the upper surface of the bearing rings being flush with the bottom edge of the mounting slots, and filter components being detachably installed inside the mounting slots.

[0004] Furthermore, the filter assembly includes a support ring movably connected inside the mounting groove. The inner wall of the support ring is coaxial and flush with the inner wall of the bearing ring. The outer wall of the support ring fits the inner wall of the filter tank and the mounting groove. An installation step is provided on the top inner side of the support ring, and a filter screen is provided inside the support ring through the installation step.

[0005] Furthermore, a handle is integrally connected to the outer wall of the support ring.

[0006] Furthermore, the pore size of the filter screen in the filter assembly gradually decreases from top to bottom.

[0007] Furthermore, an internal groove is provided in the middle of the top wall of the mounting groove, and a sealing element is provided inside the internal groove. The bottom end of the sealing element is sealed to the top wall of the support ring.

[0008] Furthermore, the inner wall of the filter screen's frame is angled.

[0009] Furthermore, the filter screen is designed with a conical surface. Beneficial effects

[0010] When filtering lithium-ion battery slurry, the raw material is squeezed in through the feed pipe. As the raw material passes through several filter components, it is filtered. When it is necessary to clean the impurities filtered out by the filter components, the filter components are removed from the inside of the mounting tank, and the impurities on the filter components are cleaned, thereby achieving the purpose of easy cleaning.

[0011] When installing the filter assembly, insert the support ring into the mounting groove, making the inner wall of the support ring coaxial and flush with the inner wall of the bearing ring to complete the installation of the filter assembly. At this time, the filter assembly is supported and fixed by the bearing ring. When cleaning the inside of the filter screen, remove the entire filter screen from the mounting step to complete the disassembly of the filter screen, and then clean the filter screen.

[0012] The filter screen is designed with a conical surface, which can effectively increase the filtration area and guide the filtered raw materials towards the central area.

[0013] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0020] Please refer to Figures 1 to 5 ;

[0021] This embodiment provides a lithium-ion battery slurry filtration device, see reference. Figure 1 and Figure 2 The filter includes: a filter tank 1, an inlet pipe 101 integrally connected to the top of the filter tank 1, an outlet pipe 102 integrally connected to the bottom of the filter tank 1, a number of mounting slots 103 sequentially opened from top to bottom in the middle of the filter tank 1, a number of bearing rings 104 corresponding to the mounting slots 103 integrally connected to the inner wall of the filter tank 1, the upper surface of the bearing rings 104 being flush with the bottom edge of the mounting slots 103, and filter components 2 being detachably installed inside the mounting slots 103.

[0022] In practice, when filtering lithium-ion battery slurry, the raw material is squeezed in from the feed pipe 101. When the raw material passes through several filter components 2, it is filtered by the filter components 2. When it is necessary to clean the impurities filtered out by the filter components 2, the filter components 2 are removed from the inside of the mounting groove 103, and the impurities on the filter components 2 are cleaned, thereby achieving the purpose of easy cleaning.

[0023] Further reference Figure 3 and Figure 4 The filter assembly 2 includes a support ring 201 movably connected inside the mounting groove 103. The inner wall of the support ring 201 is coaxial and flush with the inner wall of the bearing ring 104. The outer wall of the support ring 201 fits the inner wall of the filter tank 1 and the mounting groove 103. An installation step 212 is provided on the top inner side of the support ring 201. A filter screen 202 is provided inside the support ring 201 through the installation step 212.

[0024] In specific implementation, when installing the filter assembly 2, the support ring 201 is inserted into the installation groove 103 so that the inner wall of the support ring 201 is coaxial and flush with the inner wall of the bearing ring 104, thus completing the installation of the filter assembly 2. At this time, the filter assembly 2 is supported and fixed by the bearing ring 104.

[0025] When cleaning the inside of the filter screen 202, remove the entire filter screen 202 from the mounting step 212 to complete the disassembly of the filter screen 202, and then clean the filter screen 202.

[0026] Further reference Figure 3 A handle 211 is integrally connected to the outer wall of the support ring 201.

[0027] In practical implementation, by setting the handle 211, when the support ring 201 is removed, the handle 211 can better form a force-bearing structure, making the filter assembly 2 easy to remove as a whole.

[0028] Further reference Figure 2 The pore size of the filter screen 202 of the filter assembly 2 gradually decreases from top to bottom.

[0029] In practical implementation, by setting up multiple layers of filter screens 202 with different pore sizes, the filter assembly 2 can filter debris of different diameters, which can also reduce the pressure of a single filtration and reduce the burden on the filter screens 202.

[0030] Further reference Figure 2 An internal groove 105 is provided in the middle of the top wall of the mounting groove 103. A sealing element 106 is provided inside the internal groove 105. The bottom end of the sealing element 106 is sealed to the top wall of the support ring 201.

[0031] In practical implementation, the built-in groove 105 allows the seal 106 to be placed inside the built-in groove 105. When the support ring 201 is inserted into the mounting groove 103, the seal 106 and the top wall of the support ring 201 form a sealing structure.

[0032] Further reference Figure 5 The inner wall of the frame 221 of the filter screen 202 is inclined.

[0033] In practice, avoid leaving the raw material on the top of the border 221.

[0034] Further reference Figure 5 The filter screen 202 is arranged in a conical shape.

[0035] In practice, this can effectively increase the filtration area and guide the filtered raw materials toward the central area.
