[0026] In order to utilize centrifugal force to screen graphite auxiliary materials of different specifications and thus meet the use requirements, the centrifugal assembly includes a first motor 409, a centrifugal barrel 410 and a limiting ring 412. The first motor 409 is fixedly connected to the upper end of the mounting shell 401. The upper end of the centrifugal barrel 410 is provided with a feed hole 414. The centrifugal barrel 410 is rotatably arranged in the mounting shell 401. The centrifugal barrel 410 is fixedly connected to the output end of the first motor 409.

A plurality of connecting rods 413 are fixedly connected to the inner wall of the limiting ring 412. The connecting rods 413 are fixedly connected to the outer wall of the centrifugal barrel 410. The inner wall of the mounting shell 401 is provided with a limiting groove 408. The limiting ring 412 is rotatably adapted to the limiting groove 408.

[0027] In order to reduce the friction between the centrifugal cylinder 410 and the bottom end of the mounting shell 401 and reduce the power consumption of the first motor 409, a first annular groove 416 is provided at the lower end of the centrifugal cylinder 410, and a second annular groove 407 is provided at the bottom end of the inner wall of the mounting shell 401.

The discharge hole 415 is connected to the discharge port 406, and the discharge port 406 is connected to the feed pipe 5. The feed pipe 5 is connected to a control valve 501. The screened materials pass through the discharge hole 415 and the discharge port 406 in sequence and are then transported to the crushing mechanism 3 by the feed pipe 5.

[0030] The crushing mechanism 3 includes a second motor 303, a shell 301 and a rotating shaft 305. The shell 301 is connected to the upper end of the second bracket 2. The second motor 303 is fixedly connected to the lower end of the shell 301. The rotating shaft 305 is fixedly connected to the output end of the second motor 303. The rotating shaft 305 rotates and extends into the shell 301. A supporting sheet 304 is fixedly connected to the rotating shaft 305. The supporting sheet 304 is rotatably adapted to fit in the shell 301. A plurality of crushing blades 306 are fixedly connected to the outer periphery of the rotating shaft 305.

[0031] A protective ring 101 is fixedly connected to the upper end of the first bracket 1, and the protective ring 101 is fitted to the mounting shell 401.

The height of the shell 301 is controlled by the hydraulic rod 201. When the hydraulic rod 201 is extended, the connecting ring 302 at the upper end of the shell 301 is adapted to the feed pipe 5. When the hydraulic rod 201 is contracted, the connecting ring 302 is connected to the feed pipe 5, so that the crushing mechanism 3 can be pushed away from the lower end of the separation mechanism, and then the crushed graphite material can be collected.

[0032] When the utility model is used, the feed port 402 on the mounting shell 401 and the feed hole 414 at the upper end of the centrifugal cylinder 410 are matched and connected, and graphite materials of different specifications are sequentially put into the centrifugal cylinder 410 through the feed port 402 and the feed hole 414, and the feed port 402 is closed, and the first motor 409 is started, and the first motor 409 drives the centrifugal cylinder 410 to rotate, and the limit ring 412 rotates in the limit groove 408 to make the centrifugal cylinder 410 rotate more stably, and the centrifugal cylinder 410 rotates to generate centrifugal force so that the materials meeting the use specifications are filtered out from the filter hole 411 into the mounting shell 401, and then the materials are leaked out from the collection port 405 at the lower end of the mounting shell 401 to be collected and used, and the screened materials are sequentially filtered out.

The output end of the second motor 303 drives the rotating shaft 305 to rotate, and the support sheet 304 rotates in the shell 301 to increase the stability of the rotating shaft 305. The rotation of the rotating shaft 305 drives the crushing blade 306 to crush the material. After the material is crushed to meet the use specifications, the hydraulic rod 201 at the lower end of the second bracket 2 is controlled to contract, so that the connecting ring 302 is away from the feed pipe 5, and the second bracket 2 together with the crushing mechanism 3 is pushed out of the lower end of the first bracket 1, and the crushed graphite material that meets the use specifications in the shell 301 is taken out.

[0033] In summary: in the embodiment of the utility model, the graphite material is introduced into the centrifugal barrel 410 from the feed port 402 through the feed hole 414, and the centrifugal barrel 410 is driven to rotate by the first motor 409. The centrifugal barrel 410 is stably connected to the mounting shell 401 through the limit ring 412, thereby effectively improving the stability of the rotation of the centrifugal barrel 410. The centrifugal barrel 410 rotates so that the materials that meet the use specifications in the graphite material are filtered out of the centrifugal barrel 410 through the filter hole 411 and enter the mounting shell 401, and then fall out of the mounting shell 401 through the collecting port 405 to be collected and used. After the screening is completed, the control valve 501 is used to control the opening and closing of the feed pipe 5 so that the screened materials enter the shell 301, and the second motor 303 drives the crushing blade 306 to rotate to crush the graphite material so that it meets the use specifications.
