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.

Chinese patent publication number is CN101948301A invention patent "diatomite ceramic filter element and its preparation method" discloses a reusable energy-saving and environmental protection filter element, the ceramic filter element has a good water treatment function, but its preparation process is complicated and complicated. In the process, only the drying and calcination steps will take at least 9 days, the production efficiency is low, and the market competitiveness of the product is reduced; the invention patent "a ceramic filter element" with the Chinese patent publication number CN102824789A discloses a main component of The ceramic filter element of diatomite has good antibacterial and antiseptic effects, but its filtration accuracy is 0.1 μm to 1 μm, the filtration accuracy is low, and the filtration effect needs to be improved; in response to this problem, the Chinese patent publication number is CN101397215A invention patent "A Diatomaceous Earth Microporous Ceramic Filter Element and Its Preparation Method" discloses a diatomite microporous ceramic filter element with a filtration accuracy of 0.1 μm to 0.5 μm. and Protective Materials Safety and Hygienic Evaluation Standards (2001), it can effectively treat drinking water quality, but the preparation process of the material uses grouting molding or pressing molding, which requires preparation of different shapes in advance according to customer needs. The mold has brought a lot of inconvenience to the manufacturer; in addition, the traditional diatomite ceramic filter element is mainly composed of diatomite and other minerals such as zeolite, shells, clay and other components. Porosity and small pore diameter, but because it contains more other minerals, these minerals inevitably contain chemical elements that are harmful to human health, such as copper, lead, hexavalent chromium, etc., so this type of ceramics The use of filter elements is often very limited
