Water surface jet-flow aerator

The utility model relates to a water surface jet-flow oxygen enhancing aerator, which comprises a vertical type motor, a clutch, a propeller shaft, an improved propeller, a created diversion atomizer, a supporting box body, a supporting rod of the supporting box body, a floater of the supporting box body, etc., wherein, the propeller shaft vertically operates, and a propeller which is fixedly arranged at the lower end of the propeller shaft pushes up the water; the propeller which rotates at high speed at the water surface layer enhances the oxygen through the mixation of hydraulic jump, entrainment, jet flow aeration and shearing at the water surface, and rapidly lifts, breaks, throws and atomizes the high-speed water flow which is pushed off the water surface via the stationary diversion atomizer, and thereby, the period of gas-liquid mass transfer interface and the period of the interface update and diffusion are added; the water flow which falls back can dissolve more oxygen through entrainment, hydraulic jump, and jet flow aeration, and the oxygen enhancing efficiency of the utility model reaches 1.5-2.2KG oxygen / KW. H. The utility model has fewer parts, and the machine weight is only half of that of an impeller type aerator with the same power.
