Environment-friendly sewage treatment equipment adopting throwing type mixing

Abstract

The invention relates to environment-friendly sewage treatment equipment adopting throwing type mixing. The equipment comprises a tank, wherein a support sleeve is fixedly connected to the middle of the bottom in the tank, and a plurality of first through holes are formed in the contact position of the bottom of the support sleeve and the tank; a rotating cylinder is arranged in the support sleeve, a spiral screw conveyer is fixedly connected onto the outer side wall of the rotating cylinder, a cavity is formed in the rotating cylinder and communicated with the supporting sleeve through a plurality of second through holes formed in the side wall of the rotating cylinder, and a yielding through hole is formed in the top of the rotating cylinder; a gear ring is fixedly connected with the topof the rotating cylinder, and a plurality of third through holes are formed uniformly in the bottom of the gear ring. The equipment has the beneficial effects that sewage firstly flows downwards along diversion channels, at the same time, a second motor drives a second rotating shaft to rotate, the second rotating shaft drives a throwing body to rotate, and the sewage can collide with impact plates when flowing out of bottoms of the diversion channels, so that the sewage and a flocculating agent are better mixed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a throwing and mixing environment-friendly sewage treatment equipment. 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 ordinary people.

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
