Sewage treatment pool structure based on sewage drug purification treatment

Abstract

The present invention provides a sewage treatment tank structure based on sewage drug purification treatment, comprising: a sewage treatment tank main body; a group of lifting brackets are slidably connected to the inner side of the sewage treatment tank main body; two shafts are axially connected to the upper inner side of the sewage treatment tank main body A group of stirring transmission seats; a group of drug pipelines are fixedly connected to the inner side of the lifting bracket. By using two sets of stirring shafts to stir the sewage, the stirring speed is fast. At the same time, by setting the stirring paddles at the bottom and driving the stirring shafts up and down through the lifting bracket, the sewage of different depths is stirred to improve the stirring effect, and at the same time Realize the synchronous lifting of the drug pipeline, dosing at different depths, ensure the dosing effect, increase the diffusion speed of the drug, realize the rapid mixing of the drug and sewage and increase the mixing speed, and at the same time, the output of the stirring motor can be greatly reduced by layered stirring Power, with better economy.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and more particularly, particularly relates to a sewage treatment tank structure based on sewage drug purification treatment. Background technique [0002] In sewage treatment, it is necessary to add flocculants, coagulants, redox agents and other drugs to sewage to treat sewage. After a certain drug is added to the wastewater, the drug must first be diffused quickly and evenly into the wastewater. The water is fully mixed with the sewage, so in the sewage treatment, it is often necessary to set a stirring motor on the sewage treatment tank to stir the sewage. [0003] For example, the application number: CN201510114978.5 is a kind of medicine dosing and stirring equipment for sewage treatment, the purpose is to fully integrate the powder medicine and sewage; Shaft, liquid level gauge and guide cylinder; the primary stirring tank and the secondary stirring tank share a box body, and the...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a sewage treatment tank structure based on sewage drug purification treatment, to solve the problem that the stirring motor and dosing device on the existing sewage treatment tank are generally fixed, and the dosing position cannot be changed during use. The diffusion of the drug after the drug is slow, and the position of the stirring paddle is fixed to ensure the uniformity of mixing. At the same time, a group of motors stir the sewage at different depths at the same time. The motor load is large, which is easy to damage the motor. The motor speed is slow and it is difficult to meet the mixing needs. The problem
