Duckweed fishing device for river channel sewage treatment process

Abstract

The invention relates to the technical field of sewage treatment, and discloses a duckweed fishing device for a river channel sewage treatment process. The duckweed fishing device for the river channel sewage treatment process comprises a machine frame. Air cushions are fixedly installed on the front portion and the rear portion of the machine frame, and a turbine is fixedly installed on the leftside of the machine frame. Side wing plates are fixedly installed on the front portion and the rear portion of an inner cavity of the machine frame, supporting bases are fixedly installed on the upperportion and the lower portion of the inner side of each side wing plate, and connecting rods are arranged between the supporting bases. A tray is movably connected to the connecting rods in a sleeving mode, and first spring pipes which extend to the supporting bases are arranged at the bottom of the tray. According to the duckweed fishing device for the river channel sewage treatment process, theoperation that the turbine is driven by a driving device to rotate cooperates with the operation that a cam extrudes an air generation bag to inflate, the operation that the first spring pipes lift the tray cooperates with the operation that a second spring pipe pushes a scraping pipe, and therefore the effects that the duckweed fishing efficiency is improved, the moisture is removed, the duckweed is quickly collected, the recycling of the duckweed is facilitated, and a blade can be kept sharp for a long time are achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a duckweed fishing device used for river sewage treatment. Background technique [0002] In many remote areas of our country, due to the local people's indifference to environmental protection awareness, the indiscriminate use of pesticides, and the wanton discharge of sewage, the environment has been destroyed and the pollution is serious. Correspondingly, the eutrophication of the river water body has been caused, and the running water cannot be used for daily farming. When it is used in fields, a large amount of duckweed will emerge on the water surface of the river. When it erupts, it can occupy the entire water surface, consume oxygen in the water, and cause a large number of aquatic organisms such as fish and shrimp to die, thereby aggravating the damage to the environment. [0003] And existing a kind of duckweed salvage device when being used for river channel se...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a duckweed fishing device for river sewage treatment, which has the advantages of improving duckweed fishing efficiency, removing water, quickly collecting duckweed, and facilitating duckweed recycling. , which solves the problems of low duckweed salvage efficiency, no water removal, manual collection and transfer of duckweed in common duckweed salvage devices used for river sewage treatment, and inconvenient duckweed recycling.
