Problems solved by technology

When the filter screen moves out of the filter box, the filter screen is cleaned by the cleaning device, and the solid matter attached to the filter screen is washed away, so as to maintain the filter state of the filter screen and maintain a high filtration efficiency continuously, but the sewage is due to There are usually flocs in the sewage, and the above-mentioned and existing sewage filtration devices usually cannot effectively treat the flocs, and the flocs are easy to adsorb on the inner wall of the sewage filtration device and block the outlet of the sewage filtration device

Abstract

The invention discloses sewage filtering equipment capable of avoiding flocculate attachment. According to the invention, a fan-shaped filter screen capable of moving back and forth in a filter cartridge is designed; an annular scraping plate on the outer side of the fan-shaped filter screen can be used for effectively scraping flocculate attached to the inner wall of the filter cartridge, so; flocculate precipitation in the filter cartridge is avoided; when the moving direction of the fan-shaped filter screen is opposite to the flow direction of sewage, the sewage can pass through the fan-shaped filter screen at a higher relative flow rate, and filtration of the sewage is accelerated; three flow diversion pipes are designed to realize flow diversion of sewage in the filter cartridge; meanwhile, rotating spiral blades are arranged in the sewage filtering equipment pipes and is matched with pumping of a water pump, so the flow speed of the sewage is increased, and the filtering speed ofthe sewage is effectively increased; and through three-layer arrangement of a first filter screen, a second filter screen and a third filter screen, the sewage is subjected to three-layer filtering after filtration by the fan-shaped filter screen, so the filtering effect of the sewage is improved.

Description

technical field [0001] The invention relates to the technical field of sewage filtration, in particular to a sewage filtration equipment for avoiding floc adhesion. Background technique [0002] With the acceleration of urbanization, the discharge of urban sewage has increased rapidly. The serious situation of water pollution is becoming an important factor restricting development. Sewage treatment is an important link in the treatment of water pollution. In the process of sewage treatment, filtering sewage is an indispensable process. [0003] The patent document (201811117504.6) discloses a sewage filter box, the filter in the sewage filter box moves under the drive of the rotating roller, the filter in the filter box is in contact with the sewage, and the solid matter in the sewage is adsorbed on the filter . When the filter screen moves out of the filter box, the filter screen is cleaned by the cleaning device, and the solid matter attached to the filter screen is was...
