Preparation method of kieselguhr ceramic filter cartridge

Abstract

The invention relates to a preparation method of a kieselguhr ceramic filter cartridge. The method comprises the following steps of (1) weighing the following raw materials by mass percent: 93% to 97% of kieselguhr, 1% to 5% of fluxing pore-enlarging agent, 1% to 5% of adhesive and 0.1% to 1% of embryonic body enhancer and putting the raw materials into a stirrer to be mixed evenly by adding water after the starting of the stirrer; (2) pelleting the raw materials; (3) performing extrusion molding on an embryonic model of the ceramic filter cartridge by using a molding machine and drying the embryonic model in the air; (4) roasting; (5) firing; and (6) polishing and removing powder. Other minerals are not contained in the raw materials for preparing the kieselguhr ceramic filter cartridge, so that the injury to a human body, caused by harmful chemical elements, is avoided. In addition, the filtration precision of the kieselguhr ceramic filter cartridge is high, so that a good filtration effect is obtained. The preparation method is in the extrusion molding manner, so that the trouble caused by manufacturing the models in different shapes is avoided, which is favorable for a manufacturer to improve the production efficiency. The preparation method is short in time spending. As a result, the market competitiveness of the kieselguhr ceramic filter cartridge is further improved.
