Abstract
The utility model discloses a mechanical stirring clarification tank. After being mixed with medicaments through a pipeline static mixer, raw water directly flows into a central tube of the clarification tank; because a lifting and stirring impeller is arranged in the central tube, on the one hand, active sludge at the bottom of the tank flows back to the central tube, and on the other hand, the backflow active sludge is fully mixed with the inflow water; the flocculating activity of the active sludge is maximally utilized to reduce the addition quantity of the medicaments and further improve the outflow water quality; the outflow water from the central tube flows into a reaction zone through a flow guide cover to complete flocculation reaction and then flows into a settling zone to realize solid-liquid separation, therefore, clarified liquids on the upper layer flows through a water collection channel, and redundant obsolete sludge at the bottom of the tank is collected through a sludge scraper at the bottom of the tank and then removed regularly through a sludge discharge pipeline. The flow guide cover is adopted to relatively separate a second reaction zone from a separation zone, therefore, the civil structural style of the mechanical stirring clarification tank is greatly simplified, and the civil structure is designed and constructed conveniently.
Description
Technical field
The utility model relates to a kind of municipal water supply processing machine and stirs depositing reservoir.
Background technology
At present, domestic accelerator commonly used structure mainly is made up of first reative cell, second reative cell and separation chamber.Body top, whole pond is cylindrical shape, and the bottom is a conical butt, and triangular ring armored concrete distribution channel is established in the centre, needs to establish deflector in second reative cell.Mixing plant is formed by promoting impeller and paddle, promotes the separated place that impeller is contained in first and second reative cells.The civil engineering structure complexity, difficulty of construction is big, and equipment is installed difficulty, has seriously restricted the application of accelerator.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and the convenient equipment installation accelerator is given full play to accelerator and can be adapted to the characteristics that the influent quality turbidity changes greatly, added amount of chemical is few.
Accelerator of the present utility model, comprise water inlet pipe, outlet pipe, discharge pipeline, water leg, mud scraper, it is characterized in that: central tube first reaction zone is set in depositing reservoir central authorities, after former water and medicament mix, directly enter the depositing reservoir central tube, establish a lifting, agitator arm in the central tube, one side makes the active sludge at the bottom of the pond be back to central tube, the active sludge of backflow is fully mixed with water inlet, utilize the flocculation activity of active sludge to greatest extent, reduce the dosage of medicament, improve effluent quality.The water outlet of central tube enters second reaction zone by kuppe and finishes flocculation reaction, enter the settling zone then and make Separation of Solid and Liquid, the clarified solution on upper strata is by the water leg water outlet, at the bottom of the pond unnecessary outmoded body refuse through the pond at the bottom of mud scraper collect, regularly get rid of by the spoil disposal pipeline again.
Accelerator of the present utility model no longer adopts armored concrete triangular ring distribution channel, and by adopting the steel kuppe to separate second reaction zone is relative with the Disengagement zone.The civil engineering structure pattern of accelerator is simplified greatly, made things convenient for the design and the construction of civil engineering structure.
Accelerator of the present utility model can adapt to influent quality turbidity variation former water greatly, can be widely used at present the clarifying treatment of water treatment plant both at home and abroad.It is simple to have civil engineering structure, and equipment is installed easily, and added amount of chemical is few, and delivery turbidity is little, and operational management is convenient, and advantage such as save land area.

The specific embodiment
Accelerator of the present utility model, comprise water inlet pipe 1, outlet pipe 5, discharge pipeline 6, water leg 7, mud scraper 8, after former water and medicament mix, directly enter depositing reservoir central tube 2, establish a lifting, agitator arm 3 in the central tube, stirring and lifting by impeller, one side makes the active sludge at the bottom of the pond be back to central tube 2, the active sludge of backflow is fully mixed with water inlet, utilize the flocculation activity of active sludge to greatest extent, reduce the dosage of medicament, improve effluent quality.The water outlet of central tube 2 enters second reaction zone by kuppe 4 and finishes flocculation reaction, enter the settling zone then and make Separation of Solid and Liquid, the clarified solution on upper strata is by water leg 7 water outlets, at the bottom of the pond unnecessary outmoded body refuse through the pond at the bottom of mud scraper 8 collect, regularly get rid of by spoil disposal pipeline 6 again.By cancellation triangular ring distribution channel, and adopt the steel kuppe to separate second reaction zone is relative with the Disengagement zone, the civil engineering structure pattern of accelerator is simplified greatly, made things convenient for the design and the construction of civil engineering structure, and simplify the installation of stirring, lifting means.
