Problems solved by technology

Because this method of producing biochemical filter ceramics must use special mechanical equipment to fill the foam into the slurry, the production process is complicated, the operation is cumbersome, and the energy consumption is large, resulting in high production costs; The number and size of air bubbles are difficult to control, so the pore size of the produced product is uneven, which affects the effect of water treatment

Abstract

The invention discloses a biochemical filter ceramic used in aquaculture and a preparation method thereof. The biochemical filtration ceramics uses a sponge as a carrier. The sponge is immersed in a slurry with a certain fluidity and viscosity prepared by ceramic raw materials. After the sponge fully absorbs the slurry, it is taken out and dried, and then put into the In the kiln, the product is obtained by high-temperature sintering at a temperature of 800-1600°C. The pore size of the biochemical filtering ceramic is uniform, which is beneficial to improving the effect of water quality treatment; and the production process is simple, the production energy consumption is low, and the production cost is low.

Description

technical field [0001] The invention relates to a biochemical filter ceramic, in particular to a biochemical filter ceramic for purifying water in an aquarium breeding tank, and also relates to a preparation method of the biochemical filter ceramic. Background technique [0002] There are many biochemical filter ceramics used in aquaculture for water treatment on the market. In order to obtain these biochemical filter ceramics, the current method of preparing biochemical filter ceramics is usually to first foam the foaming agent, and then use equipment to foam the foam. It is filled into the slurry prepared with ceramic raw materials and mixed, and the slurry mixed with air bubbles is made into a green body. After drying, the green body is sintered at high temperature to make biochemical filter ceramics. Because this method of producing biochemical filter ceramics must use special mechanical equipment to fill the foam into the slurry, the production process is complicated, t...
