Multi-level graphite powder equipment and grinding method for production of new energy batteries

Abstract

The invention discloses multi-level graphite powder equipment for production of new energy batteries in the technical field of new energy batteries. The equipment comprises a grinding box, a feeding hole is formed in the left side of the top of the grinding box, a baffle plate is vertically arranged at the left side of the top of an inner cavity of the grinding box, multiple groups of feeding holes are uniformly formed in a top grinding disc in a penetration manner, and a collection box is arranged at the right side of the bottom of the inner cavity of the grinding box; when graphite particlesare added into the grinding box through the feeding hole, a motor drives a cam to rotate through a motor shaft, the cam can intermittently strike a moving rod when rotating, then the moving rod drives a top plate to move towards the left side, the top plate can drive a cutting knife group to move towards the left side until striking the baffle plate when moving towards left side, meanwhile afterthe cutting knife group strikes the baffle plate, the top plate can reset through a spring, and the cutting knife group can cut and extrude the graphite particles falling from the feeding hole to cutand smash the graphite particles when on the baffle plate.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a multi-stage grinding equipment and grinding method for graphite powder used in the production of new energy batteries. Background technique [0002] New energy battery refers to a new type of non-traditional energy battery, and new energy batteries will add graphite powder during processing and production. The chemical properties of graphite powder are relatively stable at room temperature, and it is insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and electrical conductivity, and can be used as refractory materials and conductive materials. Before graphite is processed into graphite powder, it is in the form of particles of different sizes.

[0002] New energy battery refers to a new type of non-traditional energy battery, and new energy batteries will add graphite powder during processing and production. The chemical properties of graphite powder are relatively stable at room temperature, and it is insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and electrical conductivity, and can be used as refractory materials and conductive materials. Before graphite is processed into graphite powder, it is in the form of particles of different sizes. Most of the traditional graphite powder grinding equipment can only process smaller graphite particles. Grinding treatment, when encountering larger graphite particles, it will not be able to effectively grind, resulting in unqualified quality of the ground graphite powder. For this reason, we propose a multi-stage grinding equipment and grinding method for graphite powder used in new energy battery production
