Centrifugal rotary drum type sewage filtering and recycling device

Abstract

The invention discloses a centrifugal drum type sewage filtering and recycling device. The device comprises a base, wherein the upper end of the base is fixedly connected with an outer box body, the outer box body is internally and rotatably connected with a rotary drum box, the inner wall of the rotary drum box is provided with a plurality of filtering holes, the inner bottom of the outer box body is fixedly connected with a driving motor, an output shaft of the driving motor is fixedly connected to the lower end of the rotary drum box, a mud scraping ring is slidably connected to the interior of the rotary drum box, and a plurality of bristles are fixedly connected to the circumferential outer wall of the mud scraping ring. Kinetic energy generated when the rotary drum box rotates is used for driving the sludge scraping ring to continuously rotate, under the cooperation of a reciprocating lead screw and a lead screw nut, the sludge scraping ring can move up and down in a reciprocating mode, so that sludge thrown to the inner wall of the rotary drum box is scraped off, and the situation that the sludge is accumulated on the inner wall of the rotary drum box and blocks the filtering holes is prevented; in this way, high sewage filtering efficiency can be kept without shutdown cleaning, and compared with a traditional treatment means, water resources are saved, and the overall sewage treatment efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of equipment related to sewage treatment, in particular to a centrifugal drum type sewage filtration and recovery device. Background technique

[0002] For domestic sewage, most of the fixed impurities are sludge. In the process of sewage treatment, the most effective treatment method for sewage at the initial stage is filtration. General filtration equipment can remove most solid impurities.

[0003] Among them, centrifugal filter equipment is a very common sewage filter equipment. This equipment uses the centrifugal force generated when the drum rotates at a high speed to throw the sewage containing sludge around the inner wall of the drum, forcing the sewage to pass through the filter holes on the wall of the drum. for filtering purposes. However, as the filtration time increases, some sludge will gradually block the filter holes after being thrown onto the inner wall of the drum, which greatly reduces t...
