Filtering structure of municipal drainage pipeline

Abstract

The invention provides a filtering structure of a municipal drainage pipeline. The filtering structure comprises a filtering pipe, a pipe cover and a drainage pipe, wherein an annular fixed block, a garbage filtering structure and a sediment filtering structure are arranged in the filtering pipe, the annular fixed block is fixed to the inner wall of the filtering pipe, the garbage filtering structure is arranged on the annular fixed block and comprises an inner cavity, a sand collection cavity and a sand collection groove, the sand collection cavity is formed in one side of the inner cavity and fixed to the filtering pipe, the side, close to the inner cavity, of the sand collection cavity is provided with an opening, and the sand collection groove is formed in the tops of the inner cavityand the sand collection cavity. The inner cavity runs through a first rotary shaft and a second rotary shaft, wherein the first rotary shaft is vertically arranged, the top end of the first rotary shaft is provided with a first blade arranged in the sand collection groove, the bottom end of the first rotary shaft is provided with a first bevel gear arranged in the inner cavity, one end of the second rotary shaft is provided with a second blade arranged outside the inner cavity, and the other end of the second rotary shaft is provided with a second bevel gear meshed with the first bevel gear. The pipe cover covers the top of the filtering pipe, the drainage pipe is installed at the bottom of the filtering pipe, sewage and garbage in rainwater are filtered out and cleaned away, and silt is also filtered out.

Description

technical field [0001] The invention relates to the technical field of pipeline drainage, in particular to a filtering structure for municipal drainage pipelines. Background technique [0002] Municipal drainage pipes are an important part of a city. They are responsible for removing urban sewage and rainwater. In the process of pipe drainage, it is also very important to filter the water flow in advance, which can well prevent the blockage of drainage pipes. [0003] At present, the filtering structure of the drainage pipe is too simple. Usually, a filter screen is used to filter out the bulky garbage. The filtering effect of the sediment is not good enough, and it is inconvenient to clean the garbage out. SUMMARY OF THE INVENTION [0004] According to the deficiencies of the prior art, the purpose of the present invention is to provide a municipal drainage pipe filtering structure, which can not only filter and clean large-volume garbage, but also filter sediment.
