Ceramic slag separator and gel injection molding manufacturing process thereof

Abstract

The invention discloses a ceramic slag separator and a gel injection molding manufacturing process thereof, and belongs to the technical field of slag separators. The ceramic slag separator is characterized in that a ceramic slag separator main body is made from aluminum oxide ceramic; the inner wall of the slag separator is 0.01 to 0.1mu m in roughness; the aluminum oxide ceramic is prepared from the following raw materials in percentage by mass: 54 to 60 percent of aluminum oxide, 0.8 to 1.2 percent of chitosan, 0.7 to 0.85 percent of acetic acid, 0.015 to 0.027 percent of glutaraldehyde, 0.2 to 0.35 percent of polyacrylamide and 37.985 to 43.873 percent of water. The manufacturing process comprises the following steps: adding the aluminum oxide, the chitosan and the polyacrylamide into a ball mill in batches to perform ball milling, adding the acetic acid and the glutaraldehyde into a vacuum conical stirrer, and injecting slurry into a chromium-plated steel mold for curing and molding; placing a cured and molded product into a kiln for sintering to obtain the ceramic slag separator. The inner wall of the ceramic slag separator has a mirror effect, so that the problem of loss of accepted stock is solved, the recovery rate of the accepted stock is improved, and the equipment running utilization rate is high.

Description

technical field [0001] A ceramic slag remover and its gel injection molding manufacturing process belong to the technical field of slag remover. Background technique [0002] The slag remover is a device that uses Archimedes' law and centrifugal principle to remove impurities whose density is different from that of slurry. Slag cleaners are widely used in the fields of papermaking and chemical industry. The slurry forms a high-speed swirling flow on the inner wall of the slag cleaner. During the high-speed swirling flow, the rough inner wall of the slag cleaner will cause poor slag discharge and loss of good pulp. The good pulp recovery rate of the pulp is reduced. Moreover, because the interior of the slag remover is not smooth enough, impurities often accumulate, which in turn leads to blockage of the slag remover. The running resistance of the inner wall of the slag remover is large, and the friction between the particulate impurities in the slurry and the inner wall of...

AI Technical Summary

Problems solved by technology

The slag cleaner is widely used in papermaking and chemical industry. The slurry forms a high-speed swirling flow on the inner wall of the slag cleaner. During the high-speed swirling process, the slag removal will be poor and the good pulp will be lost due to the rough inner wall of the slag remover.

Lead to a reduction in the good pulp recovery rate of the pulp

Moreover, because the interior of the slag remover is not smooth enough, impurities often accumulate, which leads to the blockage of the slag remover

The running resistance of the inner wall of the slag remover is large, and the friction between the particulate impurities in the slurry and the inner wall of the slag remover is large. In the high-speed swirling flow, the inner wall of the slag remover will be continuously worn, resulting in frequent maintenance and repair of the equipment. The loss of good pulp is serious, the power consumption is large, the actual working time is shortened, the work efficiency is reduced, and the labor intensity of operators and maintenance workers is increased.

And will repeatedly pollute the environment in the process
