1. The working principle of the porous ceramic filter
The shape and mechanism of the porous ceramic filter are similar to the working principle of the disc vacuum filter, that is, under the action of the pressure difference, when the suspension passes through the filter medium, the particles are trapped on the surface of the medium to form a filter cake, while the liquid flows out through the filter medium. , to achieve the purpose of solid-liquid separation, the difference is that the filter medium—porous ceramic filter has micropores that produce a capillary effect so that the capillary force in the micropores is greater than the force applied by vacuum, so that the micropores are always filled with liquid state, no matter under what circumstances, the ceramic filter plate does not allow air to pass through, because there is no air to pass through, the energy consumption is low during solid-liquid separation, and the vacuum degree is high. The ceramic filter mainly comprises a rotor, agitator, scraper assembly, slurry Tank, distributor, ceramic filter plate, vacuum system, cleaning system, and automatic control system.
2. Technical performance and technical advantages of ceramic filter:
Ceramic filter is a new type of high-efficiency and energy-saving solid-liquid separation equipment. It appeared in the 1980s. Adtech Jiaozuo Metallurgical Materials Co., Ltd. developed a PC series porous ceramic filter with independent property rights used in the aluminum liquid. filter. The difference between the porous ceramic filter and other solid-liquid separation equipment is that the filter medium is a ceramic filter plate. The ceramic filter plate has micropores that generate capillary action so that the capillary force in the micropores is greater than the force exerted by the vacuum, making the micropores The hole is always kept full of liquid, no matter what the situation is, it is permeable and airtight, and the vacuum degree is high. Its main characteristics are:
1. The vacuum degree is generally between -0.095-0.098MPa, the filter cake has low moisture and high output;
2. Less vacuum loss and significant energy saving;
3. The micropores of the ceramic foam filter are generally around 0.5-2um, the filtrate is clear, there is no environmental pollution, and water resources are recycled;
4. The equipment has a high degree of automation, low labor intensity, easy maintenance, and a small workload.
