Technical Field

The application relates to the field of sewage treatment, in particular to a flocculation device.

Background

Flocculation and sedimentation are necessary links in sewage treatment. Flocculation and sedimentation refer to that after a flocculating agent is put into sewage, colloid and dispersed particles of suspended matters in the sewage generate floccules and generate sedimentation under the interaction of molecular force.

At present, flocculation among the sewage treatment subsides and uses the flocculation device to go on usually, has seted up into medicine mouth on the flocculation device, with the flocculating agent through advancing in medicine mouth input flocculation device, be provided with the (mixing) shaft in the flocculation device for mix the sewage among flocculating agent and the flocculation device, reach the mesh of intensive mixing. However, since the dosing port is single and located at the top of the flocculation device, even if the flocculation device is provided with the stirring shaft to mix the flocculant and the sewage, the sewage close to the dosing port will be mixed with more coagulants than the sewage far from the dosing port due to the influence of temperature and diffusion speed, resulting in poor effect of flocculation and sedimentation.

SUMMERY OF THE UTILITY MODEL

In order to guarantee flocculating agent and sewage misce bene and promote the flocculation and subside the effect, this application provides a flocculation device.

The application provides a flocculation device adopts following technical scheme:

the utility model provides a flocculation device, including installing subaerial flocculation device main part, set up the setting bucket in the flocculation device main part and the inlet tube and the outlet pipe that are connected with the setting bucket, the inside of setting bucket is provided with carries out the (mixing) shaft that mixes the stirring and installs the stirring vane at the (mixing) shaft both sides to sewage and flocculating agent, stirring vane sets up along the (mixing) shaft interval, the (mixing) shaft all sets up to hollow and be linked together with stirring vane, the outside part of flocculation device main part is arranged in to the (mixing) shaft has been seted up into medicine mouth, the medicine mouth has all been seted up on every stirring vane.

Through adopting the above technical scheme, when needs carry out flocculation treatment to sewage, let in sewage from the water inlet in the setting vat, through stirring epaxial medicine mouth that advances, lead to the flocculating agent to the (mixing) shaft in, the flocculating agent is from stirring in axial compressor to stirring vane, rotate the (mixing) shaft, the (mixing) shaft drives stirring vane and rotates, the flocculating agent flows from the play medicine mouth on the stirring vane, the stirring vane interval sets up and makes the flocculating agent can follow the play medicine mouth of a plurality of positions and flow, simultaneously (mixing) shaft and stirring vane play the effect of stirring, flocculating agent and sewage misce bene have been guaranteed, thereby the flocculation sedimentation effect has been promoted.

Optionally, a one-way valve is installed in the wall of the medicine outlet of the stirring blade, and the one-way valve controls the flocculating agent to enter the flocculation device main body from the stirring blade so as to prevent sewage in the flocculation device main body from entering the stirring blade.
