Waste water treatment reaction tank automatic reagent feeding stirs all -in -one

The utility model belongs to waste water treatment agitating unit, concretely relates to waste water treatment reaction tank automatic reagent feeding stirs all -in -one, including the mixer, fixedly connected with automatic reagent feeding case in the pivot of mixer, the setting is drawn together at its inside cavity for storage medicine to the automatic reagent feeding case and bag to and with the drug release mouth of cavity for storage medicine intercommunication, cavity for storage medicine and drug release mouth intercommunication kneck are provided with the dog, dog and the elastic element fixed connection of setting in the flexible region of elastic element. It accomplishes the even release of medicine to the wastewater disposal basin to make to remove through the rotatory centrifugal force effect of mixer, it delivers inhomogeneously to the medicine of wastewater disposal basin to have solved traditional medicine delivery equipment, cause the mixture that is unfavorable for medicine and waste water, reduce the reaction rate, it is too high to influence work efficiency and traditional medicine delivery equipment use cost, the undue complicacy of control system, consume the electric energy, cause the maintenance, the problem that the cost is too high of maintenance, and is simple in structure, and saves resources, use the advantage that the maintenance cost is low.
