Pumping-up type aerator of water-cooled machine

Abstract

The invention relates to a pumping-up type aerator of a water-cooled machine, belonging to the technical field of aerators. The pumping-up type aerator comprises a floating body, a motor, an impeller shaft, an impeller and a conical body, wherein the motor is connected with a floating body assembly through a supporting seat and works together with the supporting seat in a way of floating on the water, a motor shaft vertically and downwards extends into water, the impeller is arranged at the lower end of the motor shaft, a motor body is arranged on a position above the water, and the conical body is arranged at the lower part of the supporting seat so that water pumped up by the impeller disperses; and the periphery of the conical body or the conical body is provided with a water guiding device enabling the motor to be cooled, the water guiding device guides a part of water pumped up by the impeller to the surface of a motor housing so that the motor is better cooled. The impeller pumps up water during forwarding; the impeller jets flow downwards during reversing to generate negative pressure, absorb air and fill gas into water so as to aerate; and a diffusion wheel diffuses water pumped up by the impeller during pumping up water to the periphery so that aeration by pumping up water in the daytime to increase photosynthesis of microorganisms in water and aeration by jetting flow at night are realized.

Description

technical field [0001] The invention relates to an aerator, in particular to a pumping type aerator with a water-cooled motor. Background technique [0002] The aerator is a life-saving and stimulating equipment for fish and shrimp in aquaculture. The existing mechanical aerators mainly include three types: waterwheel type, impeller type and water spray type. Most of the original aerators The air-cooled motor is used, and the heat dissipation conditions are not good. There are also water wheel aerators that use the impeller shaft installed horizontally to drive the impeller to set off water splashes and fall on the motor to cool the motor; the existing impeller aerators install the impeller vertically because the impeller shaft is vertical. The splashed water spreads around due to the centrifugal force, and the spray does not fall on the motor, so the existing aerators installed vertically on the impeller shaft are all air-cooled motors (except for the water jet aerator driv...

The splashed water spreads around due to the centrifugal force, and the spray does not fall on the motor, so the existing aerators installed vertically on the impeller shaft are all air-cooled motors (except for the water jet aerator driven by the submersible motor)
