Problems solved by technology

[0006] 3. Before each grouting, the temperature of the mud in the original pipeline drops, causing the mud entering the mold to be lower than the control range, and streaks are easy to appear on the surface of the green body after molding

Abstract

The invention relates to a high-pressure forming slurry supply method which comprises the following steps: selecting one adjusting tank as a working adjusting tank and the other adjusting tank as a backup adjusting tank; the aged slurry in the aging tank is injected into the work adjusting tank, and the slurry in the work adjusting tank is adjusted; the slurry in the work adjusting tank is injected into the grouting tank, and grouting is stopped after the slurry in the grouting tank reaches the second liquid level; a slurry discharging pipe connected with the grouting tank is opened, and slurry in the grouting tank is injected into the mold; when the liquid level of the grouting tank is lower than the first liquid level, the slurry in the work adjusting tank is injected into the grouting tank; after the ceramic green body of the mold is formed, residual slurry is pumped back into the backup adjusting tank through a pipeline, and slurry returning treatment is carried out on the slurry; the mud in the work adjusting tank is used up, and the mud in the backup adjusting tank is prepared; and the backup adjusting tank is connected into the grouting tank, the previous backup adjusting tank serves as the working adjusting tank, the previous working adjusting tank serves as the backup adjusting tank, and the steps are repeated.

Description

technical field [0001] The invention relates to the field of ceramic product production, in particular to a high-pressure forming mud supply method. Background technique [0002] Existing ceramic products are usually formed by grouting. The conventional production process is: the raw material department injects new slurry into the old tank for aging, and then injects the slurry in the old tank into the grouting tank for adjustment, so that the specific gravity, viscosity, and The thickness and temperature reach the control range, and then the adjusted forming slurry is pumped into the mold by the diaphragm pump through the lower slurry pipe. After the slurry is formed in the mold, the excess slurry in the mold is discharged to the row through natural slurry discharge in the pulp bucket. In the above process, a plurality of stale tanks and two grouting tanks are usually set up, and the two grouting tanks are used alternately to meet production needs. [0003] There is follo...
