Vortex concave air flotation machine

Abstract

The invention provides a vortex-concave air flotation machine, which has a simple structure and can generate a large number of small air bubbles, thereby effectively removing suspended matter and having a good sewage treatment effect; it includes an air flotation machine body, and the aerator is vertically arranged in contact with the air flotation machine body At the end of the area, the aerator includes a motor, a casing, and an impeller. The impeller is equipped with a blade, and the center of the blade is provided with an air inlet hole. The motor is fixed at the end of the casing, and the motor shaft of the motor is connected to one end of the rotating shaft. The pipe is provided with an air inlet, and the center of the rotating shaft is provided with an air inlet. It is a magnetic hollow impeller, the blades are helical blades, micro-pores are distributed on the blades, and stoppers are arranged at intervals on the inner wall of the air flotation machine body in the contact area; at least one ultrasonic generator is installed at the bottom of the air flotation machine body below the impeller , Dispersion blocks are provided on the bottom surface of the blade.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a vortex concave air flotation machine. Background technique [0002] The vortex air flotation of the prior art, the vortex air flotation directly removes the suspended solids from the wastewater, and the air flotation is generated by the air. The vortex aerator directly injects "microbubbles" into the sewage, and then passes the air diffuser impeller to "Micro-bubbles" are evenly distributed in the sewage, and the impurities in the sewage are floated up to clean up, but its disadvantages are: due to the effect of gravity, a large part of the sand particles at the bottom of the vortex concave air flotation machine cannot be discharged, and the aerator The exhaust port is directly facing the inner wall of the pipeline. When the rotating impeller rotates at a high speed, the air thrown out directly hits the inner wall of the pipeline. Due to the pressure of the pipeline, the air distri...

[0002] The vortex air flotation of the prior art, the vortex air flotation directly removes the suspended solids from the wastewater, and the air flotation is generated by the air. The vortex aerator directly injects "microbubbles" into the sewage, and then passes the air diffuser impeller to "Micro-bubbles" are evenly distributed in the sewage, and the impurities in the sewage are floated up to clean up, but its disadvantages are: due to the effect of gravity, a large part of the sand particles at the bottom of the vortex concave air flotation machine cannot be discharged, and the aerator The exhaust port is directly facing the inner wall of the pipeline. When the rotating impeller rotates at a high speed, the air thrown out directly hits the inner wall of the pipeline. Due to the pressure of the pipeline, the air distribution is uneven, the bubbles are not fine and large, and the sewage treatment effect is not ideal.
