Speed reducing impeller-free aerator

Abstract

The invention belongs to the technical field of aerators, and relates to a speed reducing impeller-free aerator. A motor is arranged in a shell consisting of a cone and a waterproof cover; the motor is connected with the shell by a supporting seat; a motor shaft is connected with an impeller shaft and vertically downwards extends to the water; a motor body is positioned above the horizontal plane; an isolating device for preventing hot air of the motor from refluxing to a motor fan cover is arranged between the waterproof cover and the motor, so that the hot air formed after heat exchange of a cooling fan and radiating fins does not reflux to the motor fan cover, and the temperature of the motor is greatly reduced; the supporting seat is connected with supporting rods, and the other ends of the supporting rods are respectively provided with a floating body; and the whole aerator works by means of the floating bodies which float on the water surface, the water stirred up by the impeller is guided around by the cone, so that the water of the lower layer is complemented and the aeration purpose is fulfilled by water convection. According to the aerator, structures such as a gear, a reduction box and the like in the prior art are abandoned, lubricating oil is not needed, a fish pond is effectively prevented from being polluted by leaked oil, and the production cost is reduced.

Description

technical field [0001] The invention relates to an aerator, in particular to a non-reducing impeller type aerator. 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: water wheel type, impeller type and water spray type. The existing impeller type aerators are all There is a gear reduction mechanism, and the structure is complicated, heavy and costly. Contents of the invention [0003] The object of the present invention is to provide a non-reducing impeller type aerator in order to overcome the defects of the prior art. [0004] The purpose of the present invention is achieved like this: [0005] The non-reduction impeller type aerator includes a floating body, a motor, an impeller shaft, an impeller, a cone and a waterproof cover, and is characterized in that the motor is installed in a shell composed of a cone and a waterproof cover, and th...
