Background Art

[0002] The negative electrode is the primary component of a lithium battery. It's made by mixing the negative electrode active material, a binder, and additives into a paste, which is evenly applied to both sides of the copper foil, dried, and rolled. Currently, the mainstream applications are artificial graphite and natural graphite. The raw materials for artificial graphite negative electrodes are categorized into three main types: coal-based, petroleum-based, and a mixture of coal and petroleum. Artificial graphite negative electrodes dominate high-end consumer and power batteries. The processing of ordinary artificial graphite requires four major steps: crushing, granulation, graphitization, and screening.

[0003] Granulation of lithium-ion battery raw materials is a key step in artificial graphite processing. The material is placed in a reactor and electrically heated according to a specified temperature curve under an inert gas atmosphere and a certain pressure. Stirring is performed at 200-300°C for 1-3 hours. The material is then heated to 400-500°C and stirred until a particle size of 10-20 mm is achieved. The material is then cooled and discharged. To ensure the stability and consistency of the granulated material's particle size, the material in the reactor and the filter in the settling tank must be regularly cleaned. Manual cleaning of the tar and material adhering to the filter is labor-intensive and time-consuming.

[0041] An industrial hot air blower 4 connected to the cleaning chamber 2 through a pipeline and used to increase the internal temperature of the cleaning chamber 2;

[0042] A carrier plate 201 for carrying a plurality of filter cartridges 3 is provided in the cleaning chamber 2, and the cleaning device further comprises a driving assembly connected to the carrier plate 201 and driving the carrier plate 201 to rotate;

[0043] The carrier plate 201 is driven to rotate by a driving assembly to drive the plurality of filter cartridges 3 to revolve around the center of the carrier plate 201 .

[0044] Specifically, this embodiment discloses a cleaning device for the filter cartridge of the reactor flue gas settling tank in the granulation production process of lithium-ion battery raw materials. The cleaning device includes a main frame 1, a cleaning chamber 2 and an industrial hot air blower 4; wherein the cleaning chamber 2 and the industrial hot air blower 4 are connected by a hot air duct, so that the industrial hot air blower 4 continuously delivers hot air to the cleaning chamber 2 to achieve the purpose of increasing the internal temperature of the cleaning chamber 2. Specifically, the industrial hot air blower 4 delivers hot air to the cleaning chamber 2 to increase the temperature in the cleaning chamber 2 to 180°C-210°C. At this temperature, the tar and dust on the surface of the filter cartridge 3 will be softened to reach a fluid state, which is more convenient for subsequent cleaning. The cleaning method of this embodiment is to drive the filter cartridge 3 to revolve and rotate. The revolution is to use the drive component to drive the carrier plate 201 to rotate to drive the filter cartridge 3 to revolve. The high-speed rotation can allow the softened tar and dust on the surface of the filter cartridge 3 to be thrown off.

[0045] Secondly, based on the above embodiment, a wire brush 205 is provided on the side wall of the cleaning chamber 2 of this embodiment; the wire brush 205 can contact the outer wall of the filter cartridge 3 close to it to drive the filter cartridge 3 to rotate by friction of the wire brush 205 on the outer wall of the filter cartridge 3.

[0046] The revolution can shake off the tar and dust on the surface of the filter cartridge 3, and the continuous friction of the outer wall of the filter cartridge 3 by the wire brush 205 can not only further brush off the tar and dust on the surface of the filter cartridge 3, but also drive the filter cartridge 3 to rotate by friction, thereby achieving the design purpose of comprehensive cleaning of the outer wall of the filter cartridge 3.

Rotating the carrier plate shaft 202 simultaneously drives the carrier plate 201 to rotate, ultimately achieving the orbital revolution of multiple filter cartridges 3 around the center of the carrier plate 201. The power of the drive motor 502 is set to achieve the purpose of driving the carrier plate 201 to rotate at high speed.

[0052] Preferably, in this embodiment, multiple filter cartridge support frames 204 are arranged at intervals along the circumference of the carrier plate 201 near its edge. The filter cartridge 3 is sleeved within the filter cartridge support frames 204. A wire brush 205, through friction with the outer wall of the filter cartridge 3, drives the filter cartridge 3 to rotate about the axis of the filter cartridge support frames 204. Finally, to remove impurities removed by brushing, a cleaning port 206 is provided in the cleaning chamber 2 of this embodiment, located below the wire brush 205.

[0053] In the above technical solution, the utility model provides a filter cartridge cleaning device for a flue gas sedimentation tank of a lithium-ion battery raw material granulation kettle, which has the following beneficial effects:

[0054] The filter cartridge cleaning device of the present invention utilizes an industrial hot air blower to heat the temperature in the cleaning chamber 2, so that the tar and dust on the surface of the filter cartridge 3 are softened to a fluid state, and utilizes a driving component to drive the carrier plate 201 to drive the filter cartridge 3 to rotate so as to use centrifugal force to shake off the tar and dust on the surface of the filter cartridge 3. At the same time, the wire brush 205 continuously rubs the surface of the filter cartridge 3 and drives the filter cartridge 3 to rotate, thereby achieving efficient and environmentally friendly cleaning of the sedimentation tank filter cartridge 3, thereby improving the quality and production efficiency of lithium-ion battery raw materials.
