[0022] See also Figure 1-5 As shown, the utility model is a solid-liquid separation component for a lithium battery crusher, comprising a mounting bracket 1 and a collecting hopper 2 arranged in a crusher box, wherein the bottom discharge end of the collecting hopper 2 is connected to an inclined material guide pipe 3; a centrifugal drive component 4 is provided on the mounting bracket 1 at the discharge end of the material guide pipe 3, and a filter cartridge 5 is provided in the centrifugal drive component 4; the filter cartridge 5 is connected to the centrifugal drive component 4 by a first spring 6, and the number of turns of the first spring 6 is 1-1.5 wires.

[0023] The crushed waste battery materials are collected by the collecting hopper and transported to the filter cartridge through the guide pipe for centrifugal dehydration. The liquid attached to the surface of the solid material is separated by centrifugal action, which can quickly and efficiently separate the liquid from the solid material.

[0024] The filter cartridge is connected to the centrifugal drive assembly through the first spring. When the centrifugal drive assembly rotates, the filter cartridge will shake, which can vibrate the material in the filter cartridge, improving the dehydration efficiency while preventing solid materials from sticking to the inner wall of the filter cartridge or in the filter through hole of the filter cartridge. The number of turns of the first spring is set at 1-1.5 wires. The vibration amplitude of the filter cartridge can effectively prevent solid materials from sticking and will not be too large, which will not affect the rotation of the filter cartridge with the centrifugal drive assembly and the spring is not easy to break under the action of centrifugal force.

[0025] The diameter of the filter cartridge 5 is larger than that of the guide tube 3 and the discharge end of the guide tube 3 is located inside the feed end of the filter cartridge 5. A leak-proof flange 7 having a diameter larger than that of the filter cartridge 5 is provided near the discharge end of the guide tube 3; an elastic discharge assembly 8 is provided at the discharge end of the filter cartridge 5. When the filter cartridge shakes during the rotation, it will collide with the end of the guide tube, further enhancing the vibration of the filter cartridge.

[0026] The leak-proof flange is provided to prevent solid materials from leaking out of the gap between the feed end of the filter cartridge and the guide tube during rotation.

[0027] In this embodiment, the centrifugal drive assembly 4 includes two annular frames 4b connected to the mounting bracket 1 through bearings 4a, at least three connecting beams 4c are evenly distributed along the circumferential direction between the two annular frames 4b, and a driving gear ring 4d that cooperates with the rotary drive device is provided on the outer wall of the middle part of the connecting beam 4c. After adopting this structure, there is sufficient support strength between the annular frame and the connecting beam, and there can be enough space for the liquid to fall.

[0028] The rotary drive device includes a gear matched with a driving gear ring, a driving motor and a transmission shaft, etc. Its specific structure and connection method are common knowledge to those skilled in the art and will not be described in detail here.

[0029] In this embodiment, a plurality of first hanging ears 9 are evenly distributed along the circumferential direction on the inner walls at both ends of the annular frame 4 b , and second hanging ears 10 corresponding to the first hanging ears 9 are provided on the outer wall of the filter cartridge 5 .

[0030] C-shaped blocks 11 are provided at both ends of the first spring 6, which are matched with the first hanging ear 9 and the second hanging ear 10 respectively, and the openings of the C-shaped blocks 11 at both ends are arranged oppositely; when the filter cartridge 5 is hung in the annular frame 4b, the C-shaped block 11 matched with the first hanging ear 9 is located at the inclined upper end, and the C-shaped block 11 matched with the second hanging ear 10 is located at the inclined lower end. When in use, the two C-shaped blocks can cling to the outer wall of the corresponding hanging ear under the action of gravity to hang the filter cartridge. When disassembly is required, the filter cartridge can be taken out by simply pushing it toward the inclined upper end, which is convenient for disassembly and assembly of the filter cartridge.

[0031] In this embodiment, both ends of the collecting hopper 2 are installed in the crusher box through the second spring 12, the number of turns of the second spring 12 is 1-1.5 wires, and a number of hemispherical impact blocks 13 are evenly distributed along the circumference on the outer wall of the discharge end of the guide pipe 3. When the crushed solid material falls into the collecting hopper, it will cause the collecting hopper to vibrate, causing the impact blocks to hit the filter cartridge, further strengthening the vibration of the filter cartridge.

[0032] In this embodiment, the mounting bracket 1 includes two annular brackets 1a connected to the two ends of the centrifugal drive assembly 4, and T-shaped plugs 1b are integrally formed at the two ends of the annular bracket 1a, and a card slot 1c corresponding to the T-shaped plugs 1b is provided on the inner wall of the crusher box. With this structure, the centrifugal assembly can be assembled outside and then installed as a whole into the crusher box, which is convenient for disassembly and assembly of the entire centrifugal assembly.

[0033] In this embodiment, the elastic discharge assembly 8 includes a material blocking door plate 8a hinged on the mounting bracket 1 at the discharge end of the filter cartridge 5, a mounting crossbeam 8b is provided in the crusher box on one side of the lower end of the material blocking door plate 8a, and a third spring 8c is provided on the mounting crossbeam 8b to cooperate with the lower end of the material blocking door plate 8a. During operation, the material blocking door plate is closely attached to the mounting bracket and the surface of the discharge end of the filter cartridge under the action of the third spring. When the solid material in the centrifugal drum assembly reaches a certain amount, the lower end of the material blocking door plate is pushed open for discharge. After a certain amount of solid material is discharged, the material blocking door plate is reset and closed under the action of the third spring, ensuring that the solid material can be fully centrifugally dehydrated without affecting the discharge of the filter cartridge.

[0034] During operation, the liquid and solid materials generated by the crushing components of the waste batteries are collected by the collecting hopper and transported to the filter cartridge through the guide pipe. They are rotated with the annular frame for centrifugal dehydration. The liquid attached to the surface of the solid material is separated by centrifugal action. After a period of centrifugal separation, the solid material pushes open the material blocking door and falls down for collection.

[0035] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
