Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a demagnetizing device for powdery lithium battery negative electrode materials. Background Technique

[0002] Lithium batteries are a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high requirements for the environment. With the development of science and technology, lithium batteries have become the mainstream.

[0003] At present, most of the existing demagnetizing devices for powdery lithium battery negative electrode materials focus on the realization of the demagnetizing function, but pay insufficient attention to the cleaning of impurities on the surface of the magnetic plate during the demagnetizing process. In actual use, the powdery negative electrode materials are likely to adhere to the surface of the magnetic plate. As the use time increases, impurities accumulate continuously, which will not only affect the magnetic field distribution of the magnetic plate, reduce the stability and reliability of the demagnetizing effect, but may also lead to incomplete demagnetization and affect the product quality. At the same time, the power transmission structure of some existing demagnetizing devices is not reasonably designed, and problems such as large power loss and unstable operation are likely to occur during the transmission process, resulting in low demagnetizing work efficiency and difficulty in meeting the requirements of large-scale production. In addition, the impurity cleaning of existing demagnetizing devices mostly relies on manual operation. Manual cleaning not only consumes a large amount of time and labor costs, but also the cleaning effect is difficult to guarantee. At the same time, there are certain safety hazards when workers frequently come into contact with the equipment. Content of the Utility Model
