Abstract

The invention discloses an urban drainage filtering and impurity removing structure, and relates to the technical field of drainage structures, the urban drainage filtering and impurity removing structure comprises a well body, a water inlet is formed in the well body, an outer layer filter screen is arranged on the upper portion of the water inlet, a well cover plate is arranged at the lower end of the outer layer filter screen, and a flow limiting assembly is arranged at the lower end of the well cover plate; the flow limiting assembly is arranged in the middle of the well body, and a sand filter screen is arranged at the lower end of the flow limiting assembly. According to the invention, a first garbage interception is formed by the outer filter screen, a second interception is formed by the flow limiting assembly, and a third silt interception is formed by the sand filter screen, so that rainwater is subjected to interception and slag interception, the drainage flow is controlled, and the effect of improving drainage is achieved.

Description

technical field [0001] The invention relates to the technical field of drainage structures, in particular to an urban drainage filter and impurity removal structure. Background technique [0002] When rainfall occurs, the rainwater will flush the soil and some domestic garbage into the city's drains. When the amount of rainwater is small, it can carry less soil and garbage, but when the rainfall is too large, the garbage carried by the rainwater will increase. And block the drain, resulting in the phenomenon of rainwater retention. [0003] In view of the above-mentioned related technical problems, it is necessary to use a drainage device with a filtering system to filter the formed rainwater and accelerate the circulation. SUMMARY OF THE INVENTION [0004] Based on this, the present invention proposes an urban drainage filter and impurity removal structure, which is used to solve the problem that the urban drainage filter residue is too much and is blocked in the prior a...
