Screening device for silicon monoxide composite negative electrode material

Abstract

The invention discloses a screening device for a silicon monoxide composite negative electrode material, and belongs to the technical field of composite negative electrode materials. The screening device comprises a box body; rotating plates are rotationally connected inside the box body; connecting rods are fixedly welded on one side of the bottoms of the rotating plates; screw rods are symmetrically arranged on two sides of the box body; fixed plates are welded on the inner wall of the box body; fixed blocks are fixedly welded on two sides of the inner wall of the box body; a filter screen is connected to one side of each fixed block in a sliding manner; mounting grooves are formed in two sides of each filter screen; an insertion block is movably inserted in one side of each mounting groove; and a spring is fixedly mounted in each mounting groove. Through the coordinated use of the screw rods, the connecting rods and the rotating plates, the feeding quantity and the feeding speed canbe effectively controlled, and the blocking is avoided, so that the screening efficiency is improved, and through the coordinated use of the insertion blocks and the springs, the filter screens can be quickly dismounted and replaced, convenience is brought to a user, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of screening composite negative electrode materials, in particular to a screening device for silicon oxide composite negative electrode materials. Background technique [0002] Sieving is a method of separating particle groups according to particle size, specific gravity, chargeability, magnetic properties and other powder properties. The operation of using a perforated sieve surface to divide mixed materials with different particle sizes into various particle size levels is called sieving. . However, there are some disadvantages in the traditional use process, such as: the filter screen and the box body of the screening device of the existing silicon oxide composite negative electrode material are fixed and welded, and the filter screen cannot be disassembled for cleaning, and most The filter screen can only filter silicon oxide composite negative electrode material of one particle size. Since the particle...

However, there are some disadvantages in the traditional use process, such as: the filter screen and the box body of the screening device of the existing silicon oxide composite negative electrode material are fixed and welded, and the filter screen cannot be disassembled for cleaning, and most The filter screen can only filter silicon oxide composite negative electrode materials of one particle size. Due to the different particle sizes of silicon oxide composite negative electrode materials after crushing, the device cannot meet the screening of particles with different diameters, and the practicability is low.

Most of the existing screening devices for silicon oxide composite negative electrode materials are fed at one time, and the amount and speed of the feed cannot be controlled. As a result, too much feed will easily cause the blockage of the filter screen, thereby reducing the efficiency of screening
