Description

Technical Field

[0001] The utility model relates to the technical field of graphite negative electrode material production, in particular to a cleaning device for graphite negative electrode material production. Background Art

[0002] Graphite negative electrode materials usually refer to negative electrode materials used in lithium-ion batteries and other batteries. They are mainly composed of graphite particles. Graphite materials have the characteristics of good conductivity, stable capacity, long cycle life and low price. In battery production, graphite negative electrode materials are processed by crushing, pulverizing, mixing and other processes and then assembled into batteries together with other electrode materials. The selection and processing of graphite negative electrode materials have an important impact on battery performance. Therefore, the quality and process parameters of graphite negative electrode materials need to be strictly controlled during the production process to ensure battery performance and stability.

[0003] During the crushing process of graphite negative electrode raw materials, graphite residues will adhere to the surface of the crushing roller. The long-term accumulation of graphite residues will affect the crushing effect and even cause poor operation or damage of the equipment. A large amount of dust will be generated during the crushing process of graphite raw materials. If the dust is not cleaned in time and effectively, it will cause environmental pollution and affect the health of the workers, which will really affect the normal service life of the equipment. Dust will also adhere to the surface of the equipment. Manual cleaning increases maintenance costs and workload, and also increases the risk of equipment failure. In response to the above problems, the inventor proposes a cleaning device for the production of graphite negative electrode materials to solve the above problems. Utility Model Content
