Description

Technical Field

[0001] The utility model relates to the technical field of microporous aerators, in particular to a microporous aerator for sewage treatment. Background Art

[0002] Microporous aerator is an essential equipment for aeration and oxygenation. The selection of aeration equipment not only affects the biological treatment effect of sewage, but also affects the land occupation, investment and operation cost of sewage treatment plant. Microporous aerators mainly include hanging chain aerator, membrane microporous aerator, rotary aerator, tube aerator, disc aerator, microporous ceramic aerator, hose aerator, etc.

[0003] After searching, it was found that the publication number is CN217398571U, and the name is a microporous aerator for sewage treatment. The application proposes that during the use of the microporous aerator, a large amount of sludge will generally accumulate on its outer wall. If the sludge is not removed, the sludge will cause certain blockage and corrosion on the surface of the aerator, thereby affecting the normal operation of the aerator. In the prior art, the treatment of the sludge on the surface of the aerator is generally done by manual regular cleaning. If the cleaning is not timely, it will cause certain troubles for people. The gas is supplied to push the slide plate and the connecting rod to move, so that the two connecting rods push the two moving blocks to move toward the middle. During the movement of the moving blocks, the brush at the lower end of the moving blocks cleans the sludge on the outer wall of the aerator body to avoid sludge accumulation for a long time and damage to the aerator body. However, the application structure is very complicated and requires a large degree of modification of the existing gas pipeline. The installation and replacement are complicated. It is also necessary to provide electricity and electronic control for the solenoid valve, which is expensive and not conducive to large-scale promotion and use. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
