Flocculation tank for wastewater treatment based on rack and gear lifting principle

Abstract

The invention discloses a flocculation tank for wastewater treatment based on a rack and gear lifting principle. The flocculation tank comprises a tank body, two lifting devices are symmetrically and fixedly connected to the side walls of the tank body, the lifting device comprises a mounting seat, the mounting seat is fixedly connected to the outer side wall of the tank body, a support column is fixedly connected to the upper side of the mounting seat, a groove is arranged in the support column, the opening of the groove faces up, a rack is arranged in the groove, the lower part of the rack is engaged with a gear, the gear is fixedly connected to a first rotating shaft and the first rotating shaft is erected on the support column. A second motor drives a second rotating shaft to rotate, the second rotating shaft drives a crank to rotate, and the crank drives a connection rod to rotate so that the connection rod drives a sliding block to move left and right in a chute and the sliding block drives a stirrer to move left and right in the tank body and thus stirring effects are improved. Horizontal turbulent flow through holes on a turbulent flow plate carry out perturbance on sewage and a flocculant so that the flocculation effect of the sewage is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a flocculation tank for sewage treatment based on the lifting principle of rack and pinion. Background technique [0002] In recent years, the discharge of industrial sewage and domestic sewage in my country has been increasing year by year. The direct discharge of untreated or improperly treated sewage into the nature has seriously affected environmental sanitation and threatened people's drinking water safety. Therefore, the treatment of sewage is imminent. Sewage treatment (wastewater treatment): 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 various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of or...

AI Technical Summary

Problems solved by technology

Common flocculants are generally in powder or granular form, and they are directly put into the sewage, causing insoluble phenomena and reducing the flocculation effect

[0004] In the prior art, stirring blades are generally used to stir the sewage in the flocculation tank. At that time, the position of the stirring blades was only limited to the same position, and it was difficult to mix the sewage and the flocculant well, resulting in flocculation. less effective
