Rolling enclosed slurry filtering device

Abstract

The invention discloses a rolling enclosed slurry filtering device. The rolling enclosed slurry filtering device includes a discharging pipe, a cylindrical support, a rolling sieve assembly and a material storage tower; the upper end of the discharging pipe is fixed on a discharging opening of a ball grinder; the upper end of the cylindrical support is fixedly connected to the lower end of the discharging pipe; the lower end of the cylindrical support is connected to a fine screen; the fine screen is fixed on a material inlet of the material storage tower; the rolling sieve assembly is fixedly arranged in the cylindrical support; the rolling sieve assembly includes a sieve disc, the center of the sieve disc is rotatably provided with a plurality of rolling shafts which are arranged side by side; and the sieve disc is provided with circular grooves around the peripheries of the rolling shafts, and the bottom surfaces of the circular grooves are provided with small holes allowing exudation of slurry. The rolling enclosed slurry filtering device can completely filter impurities in permanent magnetic ferrite raw material slurry, improve the purity of the slurry, decrease the failure rate of products, and remarkably improve the production efficiency.

Description

technical field [0001] The invention relates to the field of filtering devices for raw material slurry of permanent ferrite wet-pressed magnetic tiles, in particular to a rolling closed type slurry filtering device. Background technique [0002] Before the production process of permanent ferrite wet-pressed magnetic tiles, there is an important process of ball milling raw materials, so that the particle size of ferrite raw materials can meet the requirements of convenient molding and product performance (the particle size is generally a few tenths of a micron) . Since the product is formed by wet method, the ball milling process of raw materials is a certain proportion of raw materials plus a certain proportion of water plus a certain proportion of small steel balls are mixed and milled together. When the raw materials are ground to the required particle size, they are The ground slurry should be transported to the storage tower with compressed air through pipelines for pre...

AI Technical Summary

Problems solved by technology

Because the fine screen is made of fine steel wire, under the action of compressed air, some of the small broken steel balls in the slurry are directly thrown into the slurry in the storage tower due to the elasticity of the steel wire; because the fine screen The steel wire diameter of the mesh is small, and some irregular broken steel balls will break through the steel mesh and fall into the storage material. At the same time, the steel mesh will be damaged and more impurities will be mixed into the slurry, thus damaging the mold and making the product defective. rate increased significantly
