Embodiment 1

[0030] see Figure 1 to Figure 8 , the present invention provides a sedimentation tank for sludge treatment that can reduce sludge flocculation, including a sedimentation tank 1, the sedimentation tank 1 includes a cross brace positioning shaft 101 and a cross brace installation plate 102, the sedimentation tank 1 has a rectangular structure, and the sedimentation tank 1 There are two cross-brace positioning shafts 101 symmetrically welded on the top opening of the sedimentation tank 1; two flocculant spray parts 5 are symmetrically rotated in the top middle of the inner walls of the front and rear sides of the sedimentation tank 1; The driving mechanism 3; the top position of the outer wall on the right side of the sedimentation tank 1 is provided with a motor 4, a runner 401 is set on the top of the rotating shaft of the motor 4, and a short dial shaft is supported and welded on the outer ring of the runner 401; the runner 401 The short dial shaft on the top corresponds to t...

Embodiment 2

[0039] The inventor found that the flocculation sedimentation tank is placed under the water surface through the pipeline to discharge the flocculation mixed water and drive the water flow to mix. When working for a long time, it is easy to cause the spray hole on the flocculant spray part 5 to be blocked by dirt deposits , so that the flocculant spray part 5 cannot work normally; at the same time, the discharge of flocculation mixed water and the free mixing of sewage, the mixing efficiency of suspended impurities in sewage and flocculation mixed water is not high, slowing down the speed of flocculation and sedimentation, while the flocculation of sedimentation Impurities have been statically accumulated at the bottom of the tank for a long time and condensed into agglomerates, which is not conducive to the discharge of flocculated and precipitated impurities; therefore, the inventor has made further improvements on the basis of Example 1, and the improvement scheme is as follo...

Abstract

The invention discloses a sludge treatment sedimentation tank capable of reducing sludge flocculation, and relates to the technical field of sewage treatment devices. The sludge treatment sedimentation tank capable of reducing sludge flocculation comprises a sedimentation tank body, wherein cross arm positioning shafts are symmetrically welded to an opening in the top end of the sedimentation tank body; a motor is arranged at the top end of the right outer wall of the sedimentation tank; the middle positions of the top ends of the inner walls of the front side and the rear side of the sedimentation tank are symmetrically and rotationally sleeved with flocculant spraying pieces; a cross arm positioning shaft is sleeved with the driving mechanism in the sliding manner; the driving mechanism comprises a first rack. Through mutual cooperation of first hollow spraying piece, second hollow spraying piece, scraping plate and like, when second hollow spraying piece continues to slide into first hollow spraying piece and is aligned with medicine spraying hole in first hollow spraying piece, high-pressure liquid in second hollow spraying piece flows out of aligned liquid spraying hole and impacts liquid spraying hole, and then medicine spraying hole is cleaned. Therefore, the phenomenon that the medicine spraying holes are blocked by dirt deposition is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, in particular to a sedimentation tank for sludge treatment that can reduce sludge flocculation. Background technique [0002] Flocculation and sedimentation process means that after adding coagulant in water, the particles in it form flocs, collide with each other and coagulate during the sedimentation process, their size and quality continue to increase, and the sinking speed continues to increase to achieve the purpose of solid-liquid separation , is widely used in water supply and sewage treatment processes, mainly used to remove particulate matter in water, and the sedimentation tank is the most important main component in the flocculation and sedimentation process. [0003] For example, the patent No. CN201810266038.1 discloses a sewage flocculation sedimentation tank, including a tank body, a stirring part and a feeding part; the feeding part includes a feeding chamber and ...
