Flocculation equipment

Abstract

The invention discloses flocculation equipment which comprises a flocculation tank, a feeding device, a stirring device and mud scraping equipment, wherein the feeding device is connected with the flocculation tank; the stirring device and the mud scraping equipment are arranged inside the flocculation tank and are matched with the feeding device; the stirring device comprises a stirring shaft, stirring paddles detachably connected with the stirring shaft and a driving part for driving the stirring shaft to rotate; a storage channel is formed inside the stirring shaft; discharge channels communicated with the storage channel and discharge holes which are formed in the outer surfaces of the stirring paddles and are communicated with the discharge channels are formed inside the stirring paddles; one-way discharge devices matched with the discharge holes are arranged on the stirring paddles. The discharge holes of the flocculation equipment are directly formed in the stirring paddles, a flocculant can be directly ejected into a water body when being stirred, then the flocculation effect can be greatly improved, and a finally obtained water body is free of impurity residue and is clean.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a flocculation device. Background technique [0002] In the process of water treatment, the operation of flocculation is required. The suspended solids and other impurities in the water are gathered and enlarged by flocculants to form flocs, so as to accelerate the coagulation and sedimentation of these substances, realize solid-liquid separation, and purify the water body. In the existing flocculation, the flocculant is usually put into the flocculation tank through the feed pipe at the upper part of the flocculation tank, and then stirred by a stirring device, so that the flocculant and the water body fully react to achieve the purpose of flocculation. However, in this way, most of the flocculant has already reacted with the water body in the upper part of the flocculation tank during the input process. After stirring in the later stage, the flocculation ef...

AI Technical Summary

Problems solved by technology

However, in this way, most of the flocculant has already reacted with the water body in the upper part of the flocculation tank during the input process. After stirring in the later stage, the flocculation effect is poor, and there will still be a large amount of suspended solids or impurities in the water body. The effect of water purification is poor
