Flocculation and sedimentation device for sewage

Abstract

The invention relates to the technical field of sewage flocculation precipitation, and discloses a sewage flocculation and sedimentation device which comprises a tank body, a driving rod is arranged in the tank body, a driving groove is formed in the surface of the driving rod, a steering groove is formed in the surface of the driving rod, and a sliding seat is arranged outside the driving rod. Atop column is arranged in the sliding seat, a supporting rod is arranged on the surface of the sliding seat, a first gear is arranged on the surface of the supporting rod, a stirring rod is arranged at the end, away from the sliding seat, of the supporting rod, and a toothed rod is arranged in the tank body. According to the sewage flocculation and sedimentation device, through cooperative use ofa second gear and the toothed rod, cooperative use of the second gear and a rotating cylinder, cooperative use of a piston rod and a cylinder body, and cooperative use of an air inlet sliding block and discharging sliding block, a flocculating agent can be intermittently and movably added, the contact area of the flocculating agent and sewage is increased, the flocculating agent is added more uniformly, the adding effect of the flocculating agent is improved, and the flocculating agent and the sewage are fully mixed.

Description

technical field [0001] The invention relates to the technical field of sewage flocculation sedimentation, in particular to a sewage flocculation sedimentation device. Background technique [0002] Sewage flocculation and sedimentation is to add flocculant to the sewage to make the particulate impurities in the sewage flocculate and precipitate, so as to remove the suspended solids in the sewage and achieve the effect of sewage treatment. When the existing sewage is flocculated and precipitated, the flocculant is directly Adding to the sewage at one time, this method of adding is not easy to fully mix the flocculant with the sewage, the efficiency of flocculation and sedimentation is not high, and the effect is not good. The sewage is fully mixed, the stirring effect is not good, and the flocculation and sedimentation efficiency is not high. [0003] In order to solve the above problems, we proposed a sewage flocculation and sedimentation device, which has a good effect of f...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sewage flocculation and sedimentation device, which has good flocculant addition effect, sufficient mixing of flocculant and sewage, good mixing and stirring effect of sewage and flocculant, good sewage flocculation and sedimentation effect, and good flocculation and sedimentation effect. The advantage of high efficiency solves the problems of poor flocculant addition effect, insufficient mixing of flocculant and sewage, poor mixing and stirring effect, low flocculation and sedimentation efficiency, and poor effect when the existing sewage is flocculated and precipitated.
