Turbulent flow device for sedimentation tank applied to sewage treatment

Abstract

The invention discloses a turbulent flow device for a sedimentation tank applied to sewage treatment, belonging to the technical field of sewage treatment. The turbulent flow device comprises a base, wherein fixing mechanisms are fixedly connected to the four corners of the top of the base through supporting columns, a plurality of turbulent flow assemblies are fixedly installed in an inner cavity of each fixing mechanism, an electromagnetic water valve is fixedly installed on one side of each fixing mechanism, each turbulent flow assembly comprises a liquid pumping seat, and the bottom of each liquid pumping seat is fixedly connected with a turbulent flow column. According to the device, liquid is injected into a communicating water pipe and a water bag through an external cleaning pump body, the water bag expands and unfolds after being injected with the water liquid, and negative pressure contraction is conducted after the water liquid is pumped out, so continuous contraction and expansion of the water bag form can be achieved through water pumping circulation of the water bag; and therefore, the surface adhesion stress of particles can be destroyed by unfolding the water bag, the particles adhered to the surface of the water bag are removed, water can be pumped out during working, the cross-shaped unfolding effect is guaranteed, normal generation of vortexes is guaranteed, and cleaning adaptability is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a turbulence device for a sedimentation tank of sewage treatment. Background technique [0002] In the process of water resource purification, the sedimentation tank is a relatively important part of sewage treatment. It is a structure that uses sedimentation to remove suspended solids in water, and uses natural precipitation or coagulation of water to remove suspended solids in water. The sedimentation tank is divided into horizontal sedimentation tank and vertical sedimentation tank according to the direction of water flow. The sedimentation effect depends on the flow rate of the water in the sedimentation tank and the residence time of the water in the tank. [0003] Sewage turbulence can generate a large number of tiny eddies to increase the sedimentation efficiency. The turbulence column of the turbulence device in the prior art will be combined with pa...
