Description

Technical Field

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

[0002] Aerators generally use stirring mechanisms to dissolve more organic matter in sewage with oxygen. The stirring mechanism includes a driving device, a transmission mechanism, a rotating shaft and a stirring impeller. The driving device drives the rotating shaft to rotate through the transmission mechanism, and then drives the stirring impeller to rotate. The stirring impeller stirs the sewage to increase the contact area between oxygen and sewage. However, the stirring mechanism needs to be cleaned regularly. When cleaning, the cover of the entire aerator needs to be disassembled, and then the stirring impeller of the stirring mechanism needs to be washed with water. The whole process is time-consuming and labor-intensive, and affects the working efficiency of the aerator.

[0003] For example, the utility model disclosed in the publication (announcement) number: CN217797641U discloses an aerator self-cleaning device. It includes: a loading plate, an annular integrated water pipe, a plurality of nozzles, a water supply assembly and four electric telescopic cylinders, the loading plate has a circular hole in the middle; the annular integrated water pipe is fixedly arranged on the inner side wall of the loading plate where the circular hole is located, each nozzle is arranged at intervals along the inner side wall of the annular integrated water pipe and is connected to the inside of the annular integrated water pipe, all nozzles are spaced from the outer edge of the stirring impeller of the stirring mechanism in the aerator, the water supply assembly is fixedly arranged on the loading plate and is located at the periphery of the circular hole and is connected to the annular integrated water pipe, the four electric telescopic cylinders are arranged in a quadrilateral and are arranged on the top cover plate of the aerator, and the lower end of the telescopic rod of each electric telescopic cylinder is fixedly connected to the loading plate.

[0004] The utility model realizes the goal of self-cleaning the part where the stirring impeller is located inside the aerator.

[0005] The device of the above-mentioned utility model is provided with an annular integrated water pipe and a plurality of nozzles for cleaning the surface of the stirring impeller. However, since the nozzle is installed on one side of the structurally fixed annular integrated water pipe, the radiation range of the nozzle is limited. This results in the above-mentioned device being unable to adjust the width when cleaning stirring impellers of different sizes, so that the radiation range of the device's nozzle can meet the cleaning process of impellers of different diameters.
