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

Abstract

The invention discloses a novel flocculation device which comprises a flocculation tank, a feeding device, a stirring device and a sludge scraping device. The feeding device is connected with the flocculation tank, the stirring device is arranged in the flocculation tank and matched with the feeding device and comprises a stirring shaft, a stirring paddle and a driving part, the stirring paddle isdetachably connected with the stirring shaft, the driving part is used for driving the stirring shaft to rotate, a storage channel is arranged in the stirring shaft, a discharging channel and a discharging port are formed in the stirring paddle, the discharging channel is communicated with the storage channel, the discharging port is formed in the outer surface of the stirring paddle and communicated with the discharging channel, and a unidirectional discharging device matched with the discharging port is arranged on the stirring paddle. As the discharging port is directly formed in the stirring paddle, flocculants can be directly sprayed into a water body in stirring, flocculation effects are greatly improved, impurities remaining in the finally obtained water body are basically omitted,and the water body is clean.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a novel 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 flocculat...
