Submersible plugflow aeration machine

Abstract

The invention discloses a submersible plugflow aeration machine, which can make flow for a water body while absorbing aeration by self to oxygenate the water body, and has the advantages of simple structure, convenient manufacture and the like. The machine comprises a plugflow impeller (1), a reduction gearbox (2), a submersible motor (3), a water inlet guide vane (4), a jet flow impeller (5), a water outlet guide vane (6), an inlet pipe (7) and a throat pipe (8), wherein the plugflow impeller (1) is connected with an output shaft at a low-speed end of the reduction gearbox (2); the reduction gearbox (2) is connected with the submersible motor (3) so as to distribute power of the motor (3) and simultaneously transfer the power to the plugflow impeller (1); the water inlet guide vane (4) is simultaneously connected with the motor (3) and the water outlet guide vane (6); the jet flow impeller (5) is arranged between the water inlet guide vane (4) and the water outlet guide vane (6) and is connected with a rotor shaft at a high-speed end of the motor (3); and the water outlet guide vane (6) is provided with the inlet pipe (7) and the throat pipe (8) which is connected with the outlet guide vane (6).

Description

technical field [0001] The invention belongs to an aerator, and more particularly relates to a submersible push-flow aerator, which can create flow for the water body while self-priming aeration to oxygenate the water body. Background technique [0002] At present, aerators and mixers are often used in sewage treatment. The aerators are used to introduce air into the water, and the mixers are used to promote the flow of water. The flow prevents the precipitation of activated sludge and ensures the equilibrium of dissolved oxygen at all points in the water body. [0003] For example, Aeration Industries Intrenational Inc.'s patented product Poseidon aerator aerator is a device that integrates aerator and agitator. The two propellers of the mixer are composed of two mixing propellers. Rotating with different speeds, the larger propeller has a lower speed, which is used to realize the function of a mixer, and the smaller propeller has a higher speed, and its main function is t...

Problems solved by technology

If the blower is turned off, the device will only work as an underwater mixer

In addition, this kind of equipment has a complex structure, many auxiliary equipment, and cannot work in diving. The equipped fan must be installed above the water surface, which makes a lot of noise when working, and measures to prevent sunlight, wind, rain, and snow are also required.
