Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation, in particular to a solid-liquid separation device suitable for graphite negative electrode material fluid. Background Art

[0002] Whether it is lithium cobalt oxide, lithium manganese oxide, ternary, or lithium iron phosphate batteries, the mainstream negative electrode materials used are graphite, including natural graphite and artificial graphite. Graphite negative electrode materials account for up to 10% of batteries. The production of graphite negative electrode materials consumes resources such as petroleum (needle coke, asphalt, etc.) and crystalline natural flake graphite ore, and is an energy-intensive industry. Green recycling of discarded lithium battery graphite negative electrode materials and reuse in batteries can reduce resource and energy consumption, which is conducive to the sustainable low-carbon development of the lithium battery industry. Therefore, solid-liquid separation equipment is needed.

[0003] At present, in the prior art, graphite negative electrode materials are generally placed in a filter barrel, and then the filter barrel is rotated and centrifugal force is used to separate the solid and liquid, so as to facilitate the subsequent recovery of the graphite negative electrode materials. However, after the device is used for a long time, solid debris may adhere to the inner wall of the filter barrel, affecting the subsequent separation effect of the filter barrel. In view of this, we propose a solid-liquid separation device suitable for graphite negative electrode material fluid. Utility Model Content

[0014] The utility model provides a solid-liquid separation device suitable for graphite negative electrode material fluid. It has the following beneficial effects:

[0015] (1) The solid-liquid separation device suitable for graphite negative electrode material fluid uses a rotating device so that when the rotating shaft of the device rotates clockwise, it can drive the elastic telescopic rod 1 to rotate. Under the unidirectional limiting action of the annular ratchet, the annular ratchet drives the filter barrel to rotate, so that the graphite negative electrode material in the filter barrel can be separated into solid and liquid.

By rotating the filter barrel 5, the graphite negative electrode material in the filter barrel 5 can be separated into solid and liquid, a rotating device 6 is provided inside the shell 1, and an anti-blocking component 7 is fixedly connected to the lower side of the cover plate 2.

[0028] In the embodiment of the utility model, in order to prevent the filter barrel 5 from being blocked after long-term use, specifically, the rotating device 6 includes a rotating shaft 61, which is fixedly connected to the output shaft of the motor 3; a one-way limit assembly 62, which is fixedly connected to the bottom inner wall of the filter barrel 5, and the one-way limit assembly 62 includes an annular ratchet 621, which is fixedly connected to the filter barrel 5, and the annular ratchet 621 is clamped with an elastic telescopic rod 622, which is fixedly connected to the outer wall of the rotating shaft 61; and a connecting rod 63, which is fixedly connected to the rotating shaft On the outer wall of 61, a cleaning brush 64 is fixedly connected to one end of the connecting rod 63 away from the rotating shaft 61. The rotating shaft 61 is driven to rotate clockwise by the output shaft of the motor 3, which can drive the elastic telescopic rod 622 to rotate, and then drive the annular ratchet 621 to rotate, so that the filter barrel 5 can rotate to achieve solid-liquid separation of the graphite negative electrode material. After the filter barrel 5 is used for a long time, the cleaning brush 64 is rotated by rotating the rotating shaft 61 counterclockwise. At this time, the elastic telescopic rod 622 will not drive the annular ratchet 621 to rotate, and the cleaning brush 64 rotates relative to the filter barrel 5 to prevent the filter barrel 5 from being blocked by solid impurities.

[0029] Furthermore, in order to further prevent the filter barrel 5 from being blocked, the anti-blocking component 7 specifically includes an elastic telescopic rod 71, which is fixedly connected to the outer wall of the fixed plate 75, and a fixing frame 72 is fixedly connected to the telescopic end of the elastic telescopic rod 71, and a vertical rod 73 is fixedly connected to the fixing frame 72.

The output shaft of the motor 3 drives the rotating shaft 61 to rotate clockwise, which can drive the elastic telescopic rod 622 to rotate, and then drive the annular ratchet 621 to rotate, so that the filter barrel 5 can rotate to achieve solid-liquid separation of the graphite negative electrode material. After the filter barrel 5 is used for a long time, the cleaning brush 64 is rotated by rotating the rotating shaft 61 counterclockwise. At this time, the elastic telescopic rod 622 will not drive the annular ratchet 621 to rotate, and the cleaning brush 64 rotates relative to the filter barrel 5 to prevent the filter barrel 5 from being blocked by solid impurities. In this process, the protrusion 51 can squeeze the elastic ball 74. After the elastic ball 74 passes through the protrusion 51, the elastic ball 74 resets and knocks on the outer surface of the filter barrel 5, thereby accelerating the falling off of solid impurities on the inner surface of the filter barrel 5.
