Sewage linkage mixing and multi-stage blocking type purification device for environmental protection treatment

Abstract

The invention provides a sewage linkage mixing and multi-stage blocking type purification device for environmental protection treatment. The invention relates to the technical field of sewage treatment, and solves the problems that linkage work of multiple mixing structures cannot be realized through structural improvement so as to improve the mixing effect, and water flow vortex cannot be realized through structural improvement so as to further improve the mixing effect, and vibration cleaning of impurities on a filter screen cannot be achieved in a linkage mode while stirring and mixing areconducted. The sewage linkage mixing and multi-stage blocking type purification device for environmental protection treatment comprises a mixing box body and a mixing seat, a mixing structure is mounted in the mixing box body, and a second mixing structure is mounted on the mixing structure. Due to the facts that flow guide blocks are of a triangular prism structure, and the flow guide blocks welded to the top end face and the bottom end face of the mixing plate are arranged in a mirror image shape, when the flow guide blocks reciprocate along with the mixing seat, the flow guide blocks can reduce moving resistance, vortexes can be formed at the flow guide blocks of the triangular prism structure, and the mixing effect is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and more specifically relates to a sewage linkage mixing and multi-stage blocking type purification device for environmental protection treatment. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. A large amount of sewage will be generated in daily municipal work, which needs to be treated. The general sewage treatment is to add sewage treatment agent into the sewage pool to make it undergo a chemical reaction and purify the harmful substances in the sewage to achieve the cleanliness of the sewage. Emission Standards. [0003] For example, the application number: CN201910070541.4, the invention discloses a municipal sewage treatment device, including a box body, the bottom of the box body is provided with a support frame, both sides of the bottom of the box body a...

Problems solved by technology

[0008] In order to solve the above technical problems, the present invention provides a sewage linkage mixing and multi-stage blocking purification device for environmental protection, to solve the existing problem that the existing devices often use stirring teeth to stir the sewage in the process of mixing Mixed, it is not possible to realize the linkage work of multiple mixing structures through structural improvements to improve the mixing effect, and it is impossible to realize the vortex of the water flow through structural improvements to further improve the mixing effect; moreover, the existing devices are used in sewage In the process of filtering foreign matter, the filter screen is often easily contaminated with foreign matter, and it is impossible to realize the vibration cleaning of the foreign matter on the filter screen at the same time as stirring and mixing
