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 specifically relates to a submersible push-flow aerator, which can generate water while self-priming aeration to oxygenate the water body. Background technique [0002] At present, in sewage treatment, aerators and mixers are often used to work together. The aerator is used to introduce air into the water, and the mixer is used to promote the flow of water to create flow. On the one hand, it prolongs the time that the air stays in the water. The flow prevents the sedimentation of activated sludge and ensures the balance of dissolved oxygen in each point of the water body. [0003] For example, Aeration Industries International Inc.'s patented product Poseidon Aeration Mixer is a device that combines an aerator and a mixer. The two propellers of the mixer composed of two mixing propellers It rotates at different speeds, among which the larger propeller rotates at a lower speed, which is used to realize the ...

AI Technical Summary

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.
