Slurry filtering device for lithium battery

Abstract

The invention discloses a slurry filtering device for a lithium battery. The slurry filtering device comprises a bottom plate and a tank body, wherein supporting columns are vertically and fixedly connected to two sides of the top of the bottom plate; a vibration motor is fixedly connected to the center of the top of the tank body; sliding rods are transversely and fixedly connected to the tops oftwo sides of the tank body; a matched sliding sleeve is arranged at the end, away from the tank body, of each of the sliding rods in a sleeving manner, and the bottom of the sliding sleeve is fixedlyconnected with the inner side of the top of each of the supporting columns; a filtering plate is arranged in an inner cavity of the tank body; the right side of the tank body communicates with a slagdischarging pipe. By the arrangement of the tank body, the sliding sleeves, the vibration motor, the sliding rods, the filtering plate and a material feeding pipe, the slurry filtering device can effectively filter and block large particles in slurry by vibrating the tank body, and the large particles in the slurry are prevented from entering the next processing procedure to affect the quality ofthe lithium battery; by the arrangement of the slag discharging pipe, the filtered-out large particles can be discharged out of the tank body, and the filtering effect of the filtering plate is enhanced.

Description

technical field [0001] The invention relates to the technical field of lithium battery processing, in particular to a slurry filter device for lithium batteries. Background technique [0002] For the manufacture of electrodes of lithium-ion batteries, the positive electrode slurry is composed of binder, conductive agent, positive electrode material, etc.; the negative electrode slurry is composed of binder, graphite carbon powder, etc. The preparation of positive and negative electrode slurry includes liquid and A series of technological processes such as mixing, dissolving, and dispersing between liquids, liquids and solid materials, and in this process are accompanied by changes in temperature, viscosity, environment, etc. The slurry after mixing needs to have better stability , which is an important indicator to ensure the consistency of the battery during the battery production process. With the end of the slurry mixing, the stirring stops, the slurry will settle, floccu...
