[0023] See also Figures 1 to 4The utility model provides a technical solution: a negative electrode material filtering and separating device, comprising a filtering and separating device body, the filtering and separating device body comprising a box body 1, a power mechanism 2 is fixedly installed on the top of the box body 1, the power mechanism 2 is a DC motor, the DC motor provides power for the rotation of the output shaft 15, a feed hopper 3 is fixedly installed on the side of the power mechanism 2, a conical seat 8 is fixedly installed inside the box body 1, a fixed barrel 11 is welded and fixed at the bottom of the conical seat 8, a cavity 10 is opened inside the fixed barrel 11, a block 9 is welded on the side of the top of the cavity 10, an opening 12 is opened on the fixed barrel 11, a filter assembly is fixedly installed inside the opening 12, an output shaft 15 is fixedly installed on the power mechanism 2, a support column 16 is movably installed inside the output shaft 15, and the support column 16 is movably installed inside the cavity 10, a discharge pipe 7 is fixedly installed on one side of the box body 1, and the filter assembly is a filter plate, which is used to separate graphite and materials.

[0024] In this embodiment, a stirring plate 20 is welded to one end of the support column 16, a movable plate 21 is movably installed inside the fixed barrel 11, and the movable plate 21 is in contact with the stirring plate 20. A discharge box 4 is fixedly installed between the conical seat 8 and the box body 1, and a lifting mechanism 13 is fixedly installed at the bottom of the box body 1. A movable rod 14 is installed on the lifting mechanism 13, and one end of the movable rod 14 is welded to the movable plate 21. An ultrasonic generator 22 is fixedly installed inside the fixed barrel 11, and an installation cavity 23 is opened inside the output shaft 15. One end of the support column 16 is movably installed inside the output shaft 15. The ultrasonic generator 22 generates ultrasonic waves to vibrate the solution, and the vibration facilitates the rapid shedding of graphite on the material.

[0025] In this embodiment, a limiting groove 24 is formed on the inner wall of the installation cavity 23, a limiting block 25 is welded to one end of the support column 16, and the limiting block 25 is movably installed inside the limiting groove 24. An inclined plate 17 is fixedly installed at the bottom of the box body 1, and one end of the inclined plate 17 cooperates with the feed hopper 3. An annular tube 18 is fixedly installed at the bottom of the conical seat 8, and a drain pipe 19 is fixedly installed on the annular tube 18, and one end of the drain pipe 19 is fixed on the fixed barrel 11.

In the later stage, the solution and the graphite are discharged through the discharge pipe 7 at the same time, which is convenient for the processing and recycling of the graphite again in the later stage.
