Description

Technical Field

[0001] This utility model relates to the field of demagnetizing equipment technology, specifically to a powder demagnetizing equipment. Background Technology

[0002] Magnetic foreign matter in lithium battery cathode materials can affect the material's self-discharge, safety, and cycle performance. During the production process, electromagnetic separators and permanent magnet separators are used to remove magnetic foreign matter from the material. However, when preparing cathode powder materials in the laboratory, dust, equipment wear, and other factors can lead to an increase in magnetic foreign matter in the material, affecting its electrical performance. Furthermore, the amount of cathode material prepared in the laboratory is small, making it unsuitable to use large-scale electromagnetic demagnetizing equipment. Currently, the small amount of material prepared in experiments is almost not demagnetized after crushing, and the magnetic foreign matter in the material affects the electrical performance test results. Therefore, small-scale demagnetizing equipment is needed to remove magnetic foreign matter from the material. Chinese Patent Publication No. CN221558688U, entitled "A Demagnetizing Equipment for Powder Materials," includes a vacuum feeding device, a uniform feeding device, a first demagnetizing device, and a finished product collection device. This equipment uses a primary uniform feeding device to evenly disperse the material falling from the vacuum feeding device, and a secondary uniform feeding device to pneumatically disperse the material, so that the material falling into the demagnetizer's media mesh is in a dispersed state. A collection system is added at the finished product outlet. After the demagnetized material is dispersed by a vibrating screen, it passes through an automatic permanent magnet demagnetizing device to intercept residual magnetic impurities in the material and reduce the risk of demagnetized impurities falling into the finished product due to malfunction. Furthermore, this equipment can effectively improve the demagnetizing efficiency of the demagnetizer for materials with low magnetic properties and poor flowability. The shortcomings of the above solution are as follows: although it can demagnetize, it cannot remove impurities during use, resulting in low product purity, which may affect product quality. It also cannot easily clean magnetic impurities, as the equipment cannot easily clean them, leading to impurity accumulation and increasing the difficulty and cost of equipment maintenance and cleaning. The inconvenient cleaning process may require operators to spend more time and effort, increasing the technical problems of operational difficulty and labor intensity. Utility Model Content
