Water distributor blowdown device under filtering system

Abstract

The invention discloses a water distributor blowdown device under a filtering system. A water distributor blowdown device under a filtering system comprises a flange base, a water distribution device is installed on the flange base, an upper water distribution cap is connected to the water distribution device, a guide column pipe is arranged in the water distribution device, a water distribution pipe is installed on a guide column, a connecting swing ring is arranged on the water distribution pipe, a pipe body is connected to a pipe body, and a blowdown assembly is installed at one end of the pipe body. A pipe sealing cover is arranged on the sewage discharging assembly, an auxiliary rotating cylinder is fixed in the pipe sealing cover, an inner sleeve rod is installed on the auxiliary rotating cylinder, a piece carrying sleeve is nested outside the inner sleeve rod, and a linkage rod is arranged in the piece carrying sleeve. According to the invention, the sewage discharge assembly mounted at the tail end of the water distribution pipe can be quickly taken down and rotated after scale is formed in the pipe body, so that a scraping block of the sewage discharge assembly is expanded and attached to the inner wall of the pipe body, the scale in the pipe body is scraped, the scale is removed out of the pipe body, and the situation that the water distribution effect is affected due to blockage of the pipe body is avoided; and meanwhile, the quick pollution discharge effect on the water distribution pipe is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a water distributor sewage discharge device under a filter system. Background technique [0002] Water distribution is to arrange the amount of water evenly and regularly on a certain working area, and the device that completes this task is called a water distributor. There are many types of water distributors. It is composed of water holes, and the lower side of each branch pipe is evenly arranged with many small holes of equal distance and diameter, which are often used in water treatment and filtration systems. [0003] However, the prior art has the following deficiencies: after the current water distributor is used for a long time, the inside of the water distributor will form scale due to circulation, and the water distributor needs to be cleaned after each use for a certain period of time, otherwise the scale will become As a result, the water distribut...
