Centrifugal type double-tube activating aeration oxygen increasing machine

Abstract

A centrifugal double-barreled activation and aeration automatic aerator comprises a driving device, and is characterized in that the driving device is connected with a main shaft in a driving way, the lower end of the main shaft is provided with a horn mouth type combined centrifugal impeller, an outer coat of a fixing device is installed outside the main shaft at the upper end of the horn mouth type combined centrifugal impeller to form an oxygen gathering chamber that is communicated and provided with an oxygen supply tube, the horn mouth type combined centrifugal impeller is provided with aerobic vanes and water vanes for driving a water body to move. The centrifugal double-barreled activation and aeration automatic aerator has reasonable structural design and exterior high-pressure oxygen supply devices, thereby being capable of obviously improving the air pressure entering the water body, efficiently carrying out enforced down-diffusion for air which enters the water body, efficiently eliminating the aerobic dead angle, improving the oxygen-dissolved saturation degree, and further being capable of increasing air load amount. Air is efficiently enforced and operated to a larger and deeper water body while forming a large-scale aeration convection so that the aeration effect and the aeration scale of the water body is obviously improved. The automatic aerator can be widely applied to aeration of various water bodies in the fields of sewage purification, aquiculture, etc.

Description

technical field [0001] The invention belongs to aeration equipment for aquaculture or sewage purification, in particular to a centrifugal double-pipe activated aeration with magnetized aeration function, remarkable oxygenation effect, large water body activation depth and oxygenation range, and elimination of oxygenation dead angle Aerator. Background technique [0002] At present, there are various types of aerators used in aquaculture or sewage purification, mainly including jet spray type, impeller type, waterwheel type and aeration type. Both the impeller type and the jet water spray type aerators use water to be sprayed out to make it contact with the air to achieve the purpose of oxygenation. The waterwheel type aerator uses blades to flap in shallow water to cause waves and increase the contact area between the water surface and the air to achieve oxygenation. The above-mentioned aerators can only increase oxygen on the surface water surface, and the harmful gas in ...

AI Technical Summary

Problems solved by technology

It expands the scope of oxygenation by changing the direction in which the existing air enters the water body, and improves the effect and scope of oxygenation. However, the inventor found that there is a certain dead angle of oxygenation in the improved aerator, and the water body directly below the aerator Oxygenation effect is poor

[0005] During the oxygen-increasing aeration operation, due to the large pressure difference between the nozzle of the external oxygen inlet pipe and the air outlet channel, the external air cannot be effectively transported and diffused into the water body at a high speed, which will cause the convection range of the water body to be limited. Larger, but the oxygenation effect will not be significantly improved

Furthermore, when the air enters the water body, due to the increased buoyancy in the water body, the air will float up after a short distance diffusion, reducing the range of oxygenation.
