A non-powered self-cleaning rainwater filter device

Abstract

The invention belongs to the technical field of rainwater filtering devices, and in particular relates to a non-powered self-cleaning rainwater filtering device, which includes a water inlet three-way pipe connected to a water inlet rainwater pipeline, a water storage pipe and a four-way pipe for water storage An inlet pipe is installed on the top of the pipe, a filter is installed on the bottom, and one end of the backwash pipeline is connected to the inside. The backwash pipeline includes a vertical pipe, an upper elbow, a horizontal pipe, a Venturi tube, and a lower elbow, and the other end of the backwash pipeline The connected drain pipe is connected with a four-way pipe, the bottom side of the drain pipe is connected to the four-way pipe through the seepage pipeline, the bottom of the drain pipe is connected to the outlet rainwater pipeline, the flange blind plate connected to the top of the four-way pipe is connected to the top of the connecting frame, and the bottom of the connecting frame A filter basket is installed at the end of the cross pipe, and a filter plate is installed at the end of the four-way pipe facing the drain pipe. The combined design is low in cost and easy to assemble, which is conducive to the transportation, storage and popularization of the device. The tube speeds up and sprays out from the lower elbow to realize non-powered backwashing of the filter plate.

Description

technical field [0001] The invention belongs to the technical field of rainwater filtering devices, and in particular relates to an unpowered self-cleaning rainwater filtering device. Background technique [0002] The development of urbanization in my country has led to the increase of impervious pavements in cities. Sudden urban waterlogging caused by rainstorm runoff has become an important reason for cities to "see the sea". With the increase of high-rise buildings in cities, in midsummer, building air-conditioning and automobile exhaust will make the city's "rain island effect" worse, and rainfall runoff will carry a large amount of pollutants. However, the existing urban drainage facilities are poorly maintained and managed, and most urban drainage pipe networks are severely blocked. To solve the problem of siltation, the filtration of the source is particularly important; the rainwater channel is the primary entrance for roadside drainage, and rainwater grate is gener...

Problems solved by technology

[0003] The sediment and other sundries in the municipal rainwater pipeline are inconvenient to clean, which reduces the drainage efficiency of the rainwater well, which in turn causes the road to accumulate water, thereby affecting traffic. Although the filter screen that can filter sediment and impurities in the rainwater pipeline can be It plays the role of isolation and filtration, but it is difficult for managers to enter the buried pipeline to clean the filter
