Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment agitators, in particular to a sewage treatment agitator. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Sewage treatment is widely used in various fields such as urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people.

[0003] When treating sewage, an agitator is used to stir the sewage to make the sewage treatment more rapid. After the treatment, a lot of impurities will remain inside the shell. If the impurities are not cleaned in time, they will easily be fixed inside the shell, which will easily corrode the shell for a long time and shorten the service life of the shell. After searching, the prior art (application number: CN202320649154.8) records "a sewage treatment agitator, which relates to the field of sewage treatment technology, including an agitator assembly and a cleaning assembly. The agitator assembly includes a shell, three support legs vertically fixed to the lower end of the shell, and a mounting cover installed on the upper end of the outer side of the shell. A motor is fixed to the bottom of the shell, a stirring shaft is fixed to the output end of the motor, and stirring blades are fixed to the outer wall of the stirring shaft. The stirring shaft and the stirring blades are located inside the shell. The cleaning assembly includes a hydraulic push rod vertically fixed to the middle of the lower end of the mounting cover, and a fixing plate vertically fixed to the lower end of the hydraulic push rod. The sewage treatment agitator drives the annular water tank to move up and down inside the shell through the hydraulic push rod. During the up and down movement of the annular water tank, its outer nozzle sprays water to the outside. The sprayed water washes away the impurities remaining on the inner wall of the shell, thereby facilitating the cleaning of the impurities attached to the inner wall of the shell, preventing the impurities from corroding the shell and shortening the service life of the shell."

[0004] Although the sewage treatment agitator in the prior art achieves the flushing effect on the inner wall of the agitator shell, the cleaning component involved occupies a large space inside the shell, and the hydraulic push rod included therein cannot coexist with sewage, which affects the sewage treatment efficiency. If the cleaning component is disassembled for sewage treatment, it must be reinstalled for cleaning, which is inconvenient to use. Secondly, there is a blind spot in the spray angle of the nozzle involved, and the top of the shell cannot be cleaned. Utility Model Content
