Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] like figure 1 , figure 2 and image 3 As shown, this embodiment includes a muffler 1, a suction pipe 2, a water inlet 3, a motor 4, a diffuser pipe 5, a throat pipe 6, a mixing chamber 7, a pump casing 8, a filter screen 9, an intermittent jet 10, a nozzle 11, Suction chamber 12, deflector 13, runner 14 and shaft 15. Wherein the diffuser pipe 5, the throat pipe 6 and the mixing chamber 7 form the injection pipe.

[0029] The suction pipe 2 introduces external air, and after passing through the suction chamber 12, it is fully mixed with the liquid in the mixing chamber 7 to form a gas-liquid mixed flow; the liquid in the sewage pool enters the high-speed rotating runner 14 through the deflector 13 to obtain enough energy, and the centrifugal force Under the action, an intermittent jet flow 10 is formed; the intermittent jet flow pushes and co...

Abstract

The invention relates to a submersible runner jet aerator. The submersible runner jet aerator comprises an air suction pipeline, an air suction chamber, a runner, a fluid director and injection pipes. Liquid in a sewage pool enters the runner rotating at a high speed through an outlet of a fluid director to obtain enough energy, and is sprayed out from a nozzle on the runner under the action of centrifugal force to form intermittent jet flow. The intermittent jet flow pushes and compresses air in the air suction chamber, and the air comes from the air suction pipeline communicated with the air suction chamber. Liquid and gas are fully mixed in a mixing chamber to form gas-liquid mixed flow, and the gas-liquid mixed flow flows to throat pipes in the multiple injection pipes and is discharged from outlets of the injection pipes. According to the invention, sewage and sucked gas are mixed more uniformly, and the aeration efficiency is improved.

Description

technical field [0001] The invention relates to the aeration technology, in particular to a submersible aerator utilizing the runner jet technology. Background technique [0002] Aeration is a very important process in sewage treatment. Its function is to transport oxygen to sewage, so that aerobic microorganisms can obtain enough oxygen, degrade organic pollutants in sewage, and achieve the purpose of sewage treatment. [0003] There are two types of existing submersible aerators: centrifugal type and jet type. The centrifugal submersible aerator is composed of submersible pump, mixing chamber, intake pipe and discharge pipe. The submersible pump is placed below the liquid surface and communicated with the intake pipe. , use the centrifugal force generated by the rotation of the impeller to displace the surrounding water to form a low-pressure area. While inhaling the water flow, create a vacuum at the inlet of the impeller to inhale the air. In the air mixing chamber, the ...
