Urban rainwater filtering mechanism with impurity removing function

Abstract

The invention discloses an urban rainwater filtering mechanism with impurity removing function. The urban rainwater filtering mechanism comprises a shell, wherein the bottom portion of the shell is fixedly provided with a base, the top portion of the shell is fixedly connected to a water inlet pipe, the bottom portion of the water inlet pipe extends into the shell, the middle portion of one side of the shell is fixedly provided with a material receiving bucket, one side of the top portion of the material receiving bucket is fixedly connected to a pair of support legs, a fixing shaft is fixedlyconnected between the support legs, the upper portion of the inner cavity of the shell is provided with a filtering mechanism, and the middle portion of the inner cavity of the shell is fixedly connected to a connecting plate. According to the present invention, by arranging the filtering mechanism, the fine sand filtering box, the filtering cylinder and the precision filtering screen, dead twigs, leaves, artificial garbage and other impurities in rainwater can be discharged into urban river after multiple filtrations, such that the rainwater discharged in the urban river cannot cause environment pollution so as to achieve the good living environment.

Description

technical field [0001] The invention relates to the technical field of urban rainwater utilization equipment, in particular to an urban rainwater filtering mechanism with the function of removing impurities. Background technique [0002] Utilization of urban rainwater can be divided into narrow sense and broad sense. In the narrow sense, urban rainwater utilization mainly refers to the direct use of runoff generated by urban catchment surface after collection, storage and purification. It is commonly seen in schools, squares, building roofs, residential areas, roads, etc. The rainwater in the area is collected, adjusted and stored, and then used for green irrigation, car washing, toilet flushing, etc. This kind of utilization technology is easy to master, and it is widely used in the early stage of urban rainwater utilization research. It can produce certain effects on improving the regional environment and alleviating urban water shortage; The protection and utilization of...

Problems solved by technology

This kind of utilization technology is easy to master, and it is widely used in the early stage of urban rainwater utilization research. It can produce certain effects on improving the regional environment and alleviating urban water shortage; The protection and utilization of rainwater resources by adopting various measures, including the direct use of collection, regulation and storage, and reuse after purification; also includes the indirect use of various artificial or natural water bodies, ponds, wetlands or depressions to infiltrate rainwater to replenish groundwater resources At present, the water in urban rivers is supplemented by rainfall. When rainwater is discharged into urban rivers through pipes, it will be mixed with many impurities, such as dead branches and leaves and man-made garbage. These garbage are directly discharged into urban rivers without treatment. will pollute the urban environment
