Novel bubble-separation/ultrasonic-penetration-separation stirring-type sludge settling tank

Abstract

The invention relates to a novel bubble-separation / ultrasonic-penetration-separation stirring-type sludge settling tank which comprises a settling tank body, wherein the center of the settling tank body is provided with a distributing pipe; the upper end of the distributing pipe is provided with a motor through a rotating shaft; the upper end of the distributing pipe positioned in the settling tank body is provided with a water inlet distribution plate; the side wall is provided with movable stirring blades arranged up and down; the water inlet distribution plate is connected with a water inlet pipe; the upper and lower parts of the inner wall of the settling tank body are provided with fixed stirring blades; the upper and lower fixed stirring blades and the upper and lower movable stirring blades are arranged alternately at pulverizing intervals; the side wall of the distributing pipe is provided with an elastic telescopic water guide pipe, the end of the elastic telescopic water guide pipe is provided with a roller wheel, and the roller wheel forms a rolling contact with a guide ring on the inner wall of the settling tank body; and an ultrasonic generator is also arranged in the settling tank body, an upper water outlet pipe of the settling tank body is connected with a vacuum water pump, and the lower side wall of the settling tank body is provided with an air guide pipe connected with a blower.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a sludge sedimentation tank. Background technique [0002] The sludge water in the sedimentation tank generally needs to be pulverized. The pulverized and filtered sludge is discharged from the bottom of the sedimentation tank, and the purified water is discharged from the top of the sedimentation tank. In the existing sedimentation tank, the central shaft installed on the There is a stirring piece, and the upper end of the rotating shaft is driven by a motor. Under the rotation of the stirring piece, the sludge is crushed to reduce the existence of large mud lumps. Since the stirring blade is only arranged on the central rotating shaft, it is difficult to stir the sludge close to the inner wall of the settling tank, so it takes a long time to stir to completely break the sludge, and its working efficiency is low. Contents of the invention [0003] I...

Problems solved by technology

Since the stirring plate is only set on the central shaft, the sludge close to the inner wall of the sedimentation tank is difficult to stir, so it takes a long time to stir to completely break up the sludge, and its working efficiency is low
