Vertical submersible aeration stirrer

Abstract

The invention belongs to the field of sewage treatment, relates to sewage treatment equipment, in particular to a vertical submersible aeration stirrer. The stirrer comprises a submersible motor, a trivet, an impeller, an air deflector, a mixing chamber and an air inlet cover, and is characterized in that the submersible motor is vertically fixed on the air deflector through the trivet; the extending spindle nose of the submersible motor is downward; the impeller is fixed on the extending spindle nose of the submersible motor; the air deflector is fixed on the mixing chamber with support legs; the air inlet cover is fixed in the mixing chamber; a plurality of oblique runner holes are uniformly distributed on the periphery of the mixing chamber; and the bottom of the mixing chamber is provide with an air inlet, and can be connected with a roots blower or an air compressor. The stirrer has a unique running mode of upper water inlet, bottom air inlet and oblique peripheral water outlet, so that air is easily cut into small bubbles by the rotating impeller and mixed with water sufficiently, the aeration efficiency is greatly improved, the water inlet and outlet cannot be plugged.

Description

Technical field: [0001] The invention belongs to the field of sewage treatment, and relates to sewage treatment equipment, in particular to a vertical submersible aeration mixer. Background technique [0002] At present, the submersible aeration mixer with the function of both aeration and mixing, which is applied in the occasions of urban domestic sewage treatment, industrial wastewater treatment and fish pond oxygenation, adopts the bottom of the mixing chamber to enter the water, and the upper part to enter the air. , The surrounding tangential water outlet mode has the disadvantages of low aeration efficiency, poor mixing effect, complex structure, and easy blockage of the water inlet. Therefore, there is a need for a submersible aeration mixer with high aeration efficiency, good mixing effect, simple structure, and no clogging of the water inlet. Contents of the invention [0003] The object of the present invention overcomes the deficiencies in the prior art, and pr...
