Description

TECHNICAL FIELD

[0001] The utility model relates to filter technical field, specifically point to a detachable ceramic piece filter screen. BACKGROUND

[0002] The ceramic filter screen is a new type of filter material, and its main material is high-purity alumina and silicate, which is formed through high-temperature sintering and pressing. Due to the high hardness and chemical inertness of the ceramic material, it can withstand high temperature and high pressure, and acid and alkali, and has strong wear resistance and corrosion resistance. The filtering principle of the ceramic filter screen is mainly realized through the action of pores. Since the ceramic material itself has a fine pore structure, it can be made into a pore structure with a certain pore size and distribution through a specific manufacturing process. When liquid or gas passes through the ceramic filter screen, the tiny pores will play a screening role, separating and filtering out impurities, particles and other impurities, thereby achieving the filtering effect.

[0003] The existing ceramic piece filter screen is mostly used with a filter frame. The ceramic filter screen is connected in the filter frame, and then the filter frame is installed on the corresponding equipment. The existing filter frame is mostly provided with sliding insertion, and is fixed by relying on the friction between the filter frame and the equipment after installation. Since there is no limiting position, the filter frame is easy to shift during use, and fluid is easy to pass through the gap between the filter frame and the installation slot when the installation is not in place, resulting in incomplete filtration. Or some have a limiting position, but it is troublesome to remove the limiting position, and then the filter frame needs to be pulled out, which needs to be done in multiple steps, reducing the efficiency of maintenance and disassembly.
