Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a filtering device for sewage purification. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care and catering, and is increasingly entering the daily lives of ordinary people.

[0003] Sewage usually contains garbage such as plastic and oil. When filtering sewage, solid garbage such as plastic can easily clog the filter net, slowing down the flow of sewage, while sticky garbage such as oil can easily clog the mesh, making it impossible for sewage to be filtered and flow, reducing the filtration efficiency of sewage purification and filtration equipment.

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a filtering device for sewage purification, which can effectively solve the problems of the prior art.

[0006] (II) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The utility model discloses a filtering device for sewage purification, comprising a basic filter and a filtering mechanism, wherein a water inlet pipe is fixedly installed on the top of the basic filter, the filtering mechanism comprises a No. 1 filter plate, a No. 2 filter plate, a No. 1 guide frame and a No. 2 guide frame, a garbage cleaning mechanism is fixedly installed in the inner cavity of the basic filter, and the garbage cleaning mechanism comprises a motor, a No. 1 rotating shaft, a No. 2 rotating shaft, a No. 1 rotating frame, a No. 2 rotating frame, a No. 1 cleaning brush, a No. 2 cleaning brush, a turning box, a No. 1 gear, a No. 2 gear, a No. 3 gear and a connecting shaft.
