Sewage cleaning device for sewage treatment

Abstract

The invention discloses a sewage cleaning device for sewage treatment, and relates to the technical field of sewage treatment. The device comprises a sewage treatment tank; a pair of first supportingstrips are arranged above the sewage treatment tank side by side; a pair of mounting holes are formed in the upper surface of the first supporting strips side by side along the length direction; leadscrews vertically penetrate through the mounting holes; the outer walls of the lead screws are provided with directional grooves in the length direction; directional columns are arranged in the directional grooves in a matched mode; the directional columns are fixed in the mounting holes; screw nuts are arranged on the lead screws; the screw nuts are rotatably connected to the upper surfaces of the first supporting strips; first chain wheels sleeve the peripheries of the screw nuts; a driving motor is arranged on one first supporting strip; a second chain wheel is fixed on an output shaft of the driving motor; and the second chain wheel is in transmission connection with the four first chain wheels through chains. The device not only is simple and reasonable in structural design and convenient operate, but also effectively improves the sewage cleaning efficiency and effect, and has a high market application value.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage cleaning device for sewage treatment. Background technique [0002] The per capita level of China's fresh water resources is at the end of the world, and the problem of water pollution caused by large industrial sound fields is becoming more and more serious. Therefore, sewage treatment has attracted more and more people's attention. The existing sewage treatment methods include physical precipitation, chemical precipitation, biodegradation, etc., but no matter which method is used for sewage treatment, in the process of sewage treatment Among them, a layer of sludge will adhere to the side wall of the sewage treatment device after a period of time, and in order to ensure the normal and effective sewage treatment, the staff often need to clean the sludge on the side wall of the sewage treatment device. The existing cleaning methods are usually For manual sludge...

Therefore, sewage treatment has attracted more and more people's attention. The existing sewage treatment methods include physical precipitation, chemical precipitation, biodegradation, etc., but no matter which method is used for sewage treatment, in the process of sewage treatment Among them, a layer of sludge will adhere to the side wall of the sewage treatment device after a period of time, and in order to ensure the normal and effective sewage treatment, the staff often need to clean the sludge on the side wall of the sewage treatment device. The existing cleaning methods are usually For manual sludge removal, this method is not only time-consuming and labor-intensive, but also brings a huge workload to the staff and increases the cost of sewage treatment
