Abstract

The invention discloses a scum removing mechanism for sewage treatment. When the mechanism is used, a transmission vehicle body drives a concave screen sleeve to scrape and filter scum in a sewage pool through a toothed sleeve and a toothed rail, a flushing mechanism is used for flushing and collecting scum in the concave screen sleeve through a material receiving mechanism, so the scum removing mechanism has the advantage of effectively removing scum; meanwhile, when the screen body of the concave screen sleeve is used, through the buoyancy effect of a buoyancy ball, one half of the screen body of the concave screen sleeve is immersed into the sewage, and the other half is exposed from the sewage; and the screen body of the concave screen sleeve elastically stretches out and draws back tomove up and down below the transmission vehicle body through cooperation of a guide sliding rod and a buffer spring, so the screen body of the concave screen sleeve can intercept scum floating on sewage in a self-adaptive and self-adjusting mode, and the scum removing effect is effectively guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a scum removal mechanism for sewage treatment. Background technique

[0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields are also increasingly entering the daily life of ordinary people.

[0003] The prior art has the following problems: a scum removal device is installed on the top of some sewage treatment tanks to remove the scum, but the existing scum removal device scrapes the scum with a scraper driven by a transmission vehicle, and the water surface The removal of scum is not thorough enough. After scraping, it is necessary to manually remove the scum on the surf...
