Description

Technical Field

[0001] The utility model relates to the technical field of tubular aerator installation, in particular to a liftable tubular aerator. Background Art

[0002] The tubular aerator is a relatively new aeration device in sewage treatment. The aeration bubble diameter of this device is small, the gas-liquid area is large, the bubble diffusion is uniform, there will be no hole blockage, and it has strong corrosion resistance. It is particularly suitable for the construction and expansion of urban sewage and large factories and the renovation of old aeration tanks, and the aeration tanks can be operated intermittently.

[0003] The installation form of the tubular aerator is flexible and can be installed as a liftable aerator. The maintenance requirements of the liftable tubular aerator are low after installation, and regular maintenance and replacement can be achieved without draining water or stopping production.

[0004] The prior art publication number is CN112125391B, which includes a complete set of liftable aeration devices, including a rectangular aerator frame and an aeration membrane tube arranged on the aerator frame, and also includes a lifting system for lifting and lowering the aeration frame and at least one set of fixing mechanisms for locking the aerator frame underwater; the fixing mechanisms include a vertical upper guide rod, a lower guide rod and a guide earmuff, and the upper end of the upper guide rod is installed on the upper edge of the biological pool wall.
