Embodiment 1

[0028] refer to Figure 1-3 , a sedimentation tank for sewage treatment, comprising a sedimentation tank body 1, a mixing shell 6 is connected to one side of the outer wall of the sedimentation tank body 1 through fastening bolts, and the top outer wall of the mixing shell 6 is connected to a feeding material through fastening bolts Funnel 4, the top inner wall of the mixing shell 6 is connected with a discharge box 5 of conical structure by fastening bolts, and the circumference of the top outer wall of the discharge box 5 is provided with evenly distributed discharge ports, and the inner wall of the mixing shell 6 circumference Transition funnels 10 and deflectors 9 are alternately connected by fastening bolts, and there is a gap between the bottom of the circumference of the deflectors 9 and the circumferential inner wall of the mixing shell 6, the transition funnel 10 is a funnel-shaped structure, and the deflectors 9 is a conical structure, and the center of the outer wal...

Embodiment 2

[0039] refer to Figure 4 , a sedimentation tank for sewage treatment. Compared with Embodiment 1, this embodiment has fixed rods 15 evenly distributed on the side of the bottom inner wall of the sedimentation tank body 1 close to the feeding pipe 3 through fastening bolts, and the fixed rods 15 There are evenly distributed barbs 21 connected by fastening bolts at the circumference of each.

[0040] Working principle: the fixed rod 15 and the barb 21 buffer the loaded sewage to ensure timely and effective calm of the sewage, and the barb 21 prevents the sediment from being washed away by the loaded sewage.

Abstract

The invention discloses a sedimentation tank for sewage treatment. The sedimentation tank comprises a sedimentation tank body, a mixing shell is arranged on the outer wall of one side of the sedimentation tank body, a feeding hopper is arranged on the outer wall of the top of the mixing shell, a discharging box of a conical structure is arranged on the inner wall of the top of the mixing shell, discharging openings which are evenly distributed are formed in the circumference of the outer wall of the top of the discharging box, and transition hoppers and flow guide plates are alternately connected to the inner wall of the circumference of the mixing shell through fastening bolts. Sewage to be treated is injected into the mixing shell through the feeding funnels; meanwhile, a chemical agentis injected into the discharging box, overflows from the discharging openings and is mixed with sewage, a mixture of the chemical agent and the sewage sequentially and alternately flows through the transition funnels and the flow guide plates, so that the chemical agent and the sewage are fully mixed, a conveying pump pumps the sewage mixture mixed at the bottom of the mixing shell and injects thesewage mixture into the feeding pipe to achieve feeding, and the function of effectively mixing the chemical agent and the sewage is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sedimentation tank for sewage treatment. Background technique [0002] Sewage treatment equipment is a kind of industrial equipment that can effectively treat domestic sewage and industrial wastewater in urban areas. It prevents sewage and pollutants from flowing directly into waters, which is of great significance for improving the ecological environment, improving urban quality and promoting economic development. The sedimentation tank is an application Sedimentation is a structure that removes suspended solids in water. Sedimentation tanks are widely used in sewage treatment and are one of the most important components of sewage treatment systems. [0003] After retrieval, the Chinese Patent Publication No. is CN208869368U, which discloses a high-efficiency and environmentally friendly sedimentation tank for sewage treatment, including a shell, a control switch is i...
