Sewage treatment device with stirring roller being replaced conveniently

Abstract

The invention discloses a sewage treatment device with a stirring roller being replaced conveniently. The sewage treatment device comprises a shell, a protection cover is connected with the upper endof the shell, a water inlet pipe is mounted on one side of the shell, a protection shield is mounted on the other side of the shell, a protection pipe is mounted at the upper end of the protection cover, and a grid net is arranged in the shell; and a gas gasket is mounted on the upper surface of the grid net, a stirring shaft is arranged at the position, close to the lower part of the grid net, ofthe interior of the shell, and an oxygen pipe is arranged in the protection pipe. Through an electric heating wire and the protection pipe, the sewage treatment device can heat the oxygen when the oxygen passes through, thus the reaction rate of the oxygen and sewage can be improved. Through the grid net and the gas gasket, the gas gasket can lift the grid net up through the floating force when the sewage is injected, the relative speed of the grid net and the sewage is increased, and the filtration efficiency is improved. Through a fixer, the stirring roller can be conveniently replaced whenbeing damaged, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device which is convenient for replacing stirring rollers. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, Various fields such as catering are increasingly entering the daily life of ordinary people. The traditional sewage treatment device has a complex structure and single function. The traditional sewage treatment device does not have a grille net, or the grille net is not equipped with an air gasket. , leading to low filtration efficiency of the grid mesh. The traditional sewage treatment device does not heat the oxygen when the oxygen is introduced, resulting in a slow r...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the complex structure and single function of the traditional sewage treatment device in the prior art. The traditional sewage treatment device is not equipped with a grid net, or the grid net is not equipped with an air gasket, resulting in low filtration efficiency of the grid net. , the traditional sewage treatment device does not heat the oxygen when it is fed with oxygen, which leads to a slow reaction between the sewage and oxygen inside the device. When stirring the sewage, it is necessary to use the stirring roller, which leads to a large loss of the stirring roller. However, the traditional It is inconvenient to replace the mixing roller in the sewage treatment device. The traditional sewage treatment device cannot automatically isolate the interior of the device from the water inlet pipe after the sewage enters.
