Description

Propeller type sewage interception device

technical field

The invention relates to a sewage intercepting device, in particular to a sewage intercepting device installed on the outlet of a drainage pipe.

Background technique

After the urban roof, road, green space and other underlying surfaces are washed by rainwater, many pollutants such as fallen leaves, sludge, domestic garbage, etc. may be discharged into the river through rainwater pipes. In order to reduce the blockage of such pollutants into the pipeline, and also enter the water body to cause water pollution, it is necessary to install a sewage interception device on the rainwater discharge channel to intercept the pollutants. At present, most of the domestic sewage interception devices are installed at the outlet of the drainage pipe, mainly using direct filtration. However, in the process of rainwater transportation, there will still be a lot of sediment and dirt remaining, causing pollution and blockage. The sewage interception device installed at the outlet of the pipe network can effectively intercept the sewage at the end of the pipe network entering the river, that is, directly place a cage or a grate at the outlet of the pipeline to simply filter the sewage at the outlet. However, this method is generally not easy to clean up the retained dirt, and may even lead to poor drainage due to excessive dirt.

The problems existing in the prior art are: large-scale drainage and sewage interception devices are not easy to replace and clean, and small sewage interception devices are easy to block and lead to poor drainage. Therefore, it is necessary to design a device that separates the functions of drainage, filtration and sewage collection, so as to separate the intercepted sewage. Dirt is collected centrally for quick replacement and cleaning.
