Description

Technical Field

[0001] The invention belongs to the technical field of water purification, and in particular relates to an inclined tube automatic flushing system for a sedimentation tank and a manufacturing method thereof. Background Art

[0002] At present, high-efficiency sedimentation tank is a highly efficient water treatment technology, which has been widely used in my country and many industrially developed countries. The improvement of sedimentation effect of high-efficiency sedimentation tank is based on the reverse flow system of inclined tubes. The water after coagulation and flocculation enters the bottom of the sedimentation tank, and then flows upward from the bottom of the inclined tube through the channel formed between the inclined tubes. The particles and flocs are deposited on the plate of the inclined tube and slide down due to the action of gravity.

[0003] The particles and flocs on the inclined tube usually slide to the bottom for concentration and sedimentation due to the effect of gravity. This often causes particles and flocs to adhere to the inclined tube due to their high viscosity, resulting in an unbalanced and unstable rising water flow in the inclined tube area. The accumulated particles and flocs easily clog the inclined tube, which is difficult to clean after being clogged, resulting in low efficiency and inconvenient operation and maintenance, which affects the effluent quality and reduces the treatment efficiency of the high-efficiency sedimentation tank.

[0004] To this end, our company has developed an automatic flushing system and manufacturing method for inclined tubes for sedimentation tanks, which can improve the balance and stability of the rising water flow in the inclined tube area, avoid the accumulation of particles and flocs, and improve the sedimentation efficiency, so as to overcome the defects existing in the inclined tube sedimentation of existing high-efficiency sedimentation tanks.
