Vertical bowl loading method for production of lithium battery cathode material

Abstract

The invention provides a vertical bowl loading method for production of a lithium battery cathode material. The vertical bowl loading method comprises the following steps: S1, feeding fall adjustment: controlling a specific position of a carrier through a module system, and butting the carrier with a feeding port by controlling the carrier to move in three X-axis, Y-axis and Z-axis directions; and S2, feeding precision control: carrying out variable pitch design through carrying out matching on a feeding bin and a stirring system and through a screw in a screw feeding system. The vertical bowl loading method for production of the lithium battery cathode material, which is provided by the invention, is applicable to a vertical feeding process for the lithium battery cathode material, and is accurate to control dust raising and precision; the material compactness condition can be improved; the production capacity can be improved; moreover, in the feeding process, the situation that dust escapes all around is avoided; in addition, faults during operation are reduced; the vertical bowl loading method can be effectively compatible to multiple batches of materials; the bowl loading precision is improved; raised dust is reduced; the feeding efficiency is effectively improved; the sealing grade is greatly improved; dust is effectively isolated; and the like.

Description

technical field

[0001] The invention relates to the field of preparation of lithium battery materials, in particular to a vertical bowl filling method for the production of positive electrode materials of lithium batteries. Background technique

[0002] With the gradual development of new energy technologies, the demand for clean energy is increasing at home and abroad. Lithium battery cathode material, as one of the four core materials of battery materials, restricts the overall performance of batteries. Foreign manufacturers have been based on lithium battery cathode materials earlier and have accumulated rich experience. In the fierce competition and cleaning of the market, a group of advanced lithium battery cathode material equipment manufacturers have emerged. Due to insufficient technical reserves, domestic equipment manufacturers are still unable to form effective competitiveness.
