Intelligent grinding equipment capable of screening raw material particles

Abstract

The invention belongs to the technical field of grinding equipment, and particularly relates to intelligent grinding equipment capable of screening raw material particles. A grinding unit is mounted in the shell; a screen plate is arranged in the shell below the grinding unit; a box body is fixedly connected to one side of the shell; a collecting opening and a recycling opening are formed in the side face of the shell. A lifting unit is mounted in the box body; a collecting box is slidably connected into the box body. The inner side wall, away from the shell, of the collecting box is fixedly connected with an electric control spray head. Large-particle unqualified materials roll into the collecting box through the inclined surface of the screen plate, after a certain amount of materials are collected in the collecting box, the collecting box is lifted to a recycling opening through the lifting unit, an electric control spray head is opened and sprays air, and the materials in the collecting box are blown into the grinding unit; and large-particle unqualified materials can be recycled and ground again, the percent of pass of graphite powder is increased, and the recycling efficiency of the unqualified materials is improved.

Description

technical field [0001] The invention belongs to the technical field of grinding equipment, in particular to an intelligent grinding equipment capable of screening raw material particles. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. During the production of lithium batteries, grinding equipment is required to grind graphite into powder. [0003] A Chinese patent with the publication number CN106861839B discloses a graphite crushing and grinding device for lithium batteries, including a crushing device and a grinding device; the crushing device is provided with a material inlet, a fastener, a first motor, a pipeline, a casing, Spherical screens, connecting rods, spheres, spherical rods, blades, conveyor belts, raw material storage boxes, handles and turning points; the feed inlet has two symmetrical fixed connections at both ends of the...

AI Technical Summary

Problems solved by technology

[0004] In the current prior art, after the graphite is ground into powder, it is necessary to sieve the graphite powder, separate the powder with larger particles, and manually return the powder with large particles to the grinder for regrinding, so as to save materials and To improve the qualified rate of graphite powder, the process of manual refeeding is more cumbersome, it needs to be transported up and down continuously, and the work efficiency is low
