Description

Technical Field

[0001] The utility model relates to the technical field of aerators, in particular to a lifting device for an aerator. Background Art

[0002] Aeration tank is a kind of equipment used for oxygenation in sewage treatment system. Its basic principle is to use aerator. Aerator sprays or stirs air in water to increase oxygen content in water, promote microbial metabolism in water, accelerate oxidation and decomposition of organic matter in water, and promote the sedimentation of particulate matter in water. Traditional aerators are generally fixed at the bottom of sewage aeration tank. After a period of use, microporous aerators may be affected by suspended matter or water flow state, and may become blocked or malfunction, requiring maintenance.

[0003] After searching, the patent document with publication number: CN217377482U discloses a lifting device for a microporous aerator; by closing the gas volume regulator and disassembling the detachable joint, the crank handle of the driving wheel is turned counterclockwise, and the lifting device lifts the frame and the bracket upward through the wire rope. When the required height is reached, the fixing pin is slid down along the slide groove into the card slot of the driving wheel. In this way, the height of the wire rope can be fixed. Repair the tubular microporous aerator.

[0004] When the above device is in use, since the existing aeration tank generally adopts a circular or rectangular structure with a certain depth and area, multiple aerators need to be installed for aeration; after the frame and the bracket are lifted upward by the wire rope, the tubular microporous aerator is driven to rise, but a large number of microporous aerators have a certain distance between each other during installation and laying. If the aerator assembly is lifted as a whole, the aerator installed in the center cannot be reached. If it is lifted individually, multiple lifting devices are required for installation. The overall structure is complicated and the cost is high. After it is installed in the center of the aeration tank, it is not easy to maintain. Therefore, we propose an aerator lifting device to solve the above problem. Utility Model Content
