A sludge stirring device for environmental treatment

Abstract

The invention relates to the technical field of sludge flocculation, and discloses a sludge stirring device for environmental treatment, including a stirring tank, the inner wall of the stirring tank is equipped with a lifting component, and the lifting component is used to drive the installation component along the central axis of the stirring tank The direction is lifted, and the stirring assembly, the spraying assembly and the pumping assembly are installed on the installation assembly. In the present invention, the lifting component drives the installation component to lift at a fixed distance, so that the stirring component, the spraying component and the pumping component carry out layered sedimentation of the particulate matter in the sewage in the stirring tank, and discharge the sewage in which the particulate matter has been flocculated and precipitated, realizing the separation. The layer-by-layer sedimentation avoids the problem that the flocs are still floating in the entire container under the action of the overall swirling flow, and cannot achieve regionalized sedimentation.

Description

technical field [0001] The invention relates to the technical field of sludge flocculation, in particular to a sludge stirring device for environmental treatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Flocculation and sedimentation tank is currently the most economical and efficient process for treating suspended solids at home and abroad. Sludge is formed by sedimentation of particulate matter in sewage by adding flocculants....

AI Technical Summary

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a sludge stirring device for environmental treatment, which has the advantages of layer-by-layer sedimentation, accelerated flocculation and sedimentation, etc., and solves the problem that the flocs are still in the entire container under the action of the overall swirl. Floating, unable to achieve fixed-area sedimentation and slow settling speed and low efficiency of flocs after flocculation of sewage and chemicals

[0011] In order to solve the technical problems that the flocs are still floating in the entire container under the action of the overall swirling flow, the sedimentation in a fixed area cannot be realized, and the settling speed of the flocs after the flocculation of sewage and chemicals is relatively slow and the efficiency is low, the present invention provides the following Technical solutions:
