Description

A flocculant stirring device

technical field

The utility model relates to the field of stirring equipment, in particular to a flocculant stirring device.

Background technique

The rapid dissolution or dispersion of flocculants has always been a problem in the sewage treatment industry. Since flocculants are mostly high-molecular organic substances, when they are dissolved in water, they are often dissolved or dispersed insufficiently, resulting in a large amount of flocculants that have not been fully dissolved or dispersed. When it is added to the sewage, it does not have the proper flocculation and sedimentation effect, but has a negative impact on the subsequent sludge dehydration. When the flocculant dissolves or disperses, in addition to a certain intensity of stirring, it is also necessary to control the water temperature. Generally, the higher the water temperature, the faster the flocculant dissolves or disperses, and the more completely it dissolves or disperses.

At present, the flocculant stirring device includes a motor, a reducer, a transmission frame, a stirring shaft, a stirring blade, and a body, and several baffles are installed vertically or obliquely on the inner wall of the straight cylinder on the upper part of the body; when the stirring shaft drives the stirring blade to rotate, the pulp and flocculation The agent is thrown onto the inner wall of the upper straight cylinder of the body, and then the baffle plate is used to prevent the rotation of the pulp and flocculant, which plays a simple mixing role. The flocculant is not completely dissolved, the molecular chain is short, and the flocculation effect of the flocculant is poor.
