Description

Technical Field

[0001] The utility model relates to the technical field of negative electrode material preparation, in particular to a biomass derived hard carbon negative electrode material preparation device. Background Art

[0002] As an energy storage body, lithium battery has a relatively stable structure, especially its internal components, which are very chemically stable. In the production process of lithium batteries, the raw materials need to be sterilized after mixing, and in the sterilization process, the raw materials need to be treated with sterilizing liquid. After the sterilization treatment, the raw materials will contain a certain amount of moisture, so they need to be dried. At this time, drying equipment is needed; according to the "lithium battery raw material drying equipment" provided by Chinese patent publication number CN117781647A, the size of the feed port is changed by extending and retracting the electric telescopic rod, and at the same time, the diversion baffle on the baffle plate is used to guide the raw materials before they fall on the conveyor belt, and then the amount is controlled, so that the raw materials are formed along the first baffle and the feed port. When the raw materials enter the conveyor belt through the gap, they can be spread out and have a certain uniformity. A first scraper is arranged in the connecting pipe at the front end, and the raw materials on the transmission belt are more evenly distributed through the first scraper. At the same time, the first scraper can adjust the upper and lower positions through the gear transmission structure composed of the upper rotating control rod, the second bevel gear and the first bevel gear through the threaded rod, so that the raw materials can be evenly spread out at different heights on the transmission belt according to different needs; however, in the preparation process of biomass-derived hard carbon negative electrode materials, the biomass needs to be dried, and the wet biomass raw materials directly enter the interior of the drying box, resulting in a long drying time for the raw materials and a relatively low drying efficiency. The faster biomass raw materials are transmitted inside the drying box, which is not conducive to the drying of the raw materials;

[0003] To this end, a biomass-derived hard carbon negative electrode material preparation device is designed to solve the above problems. Utility Model Content
