Abstract

A water wheel oxygen increase machine is used for aquiculture, and comprises a motor, a reducer, water wheels and buoys. The motor is a water cooled motor, and forms a completely closed structure jointly with the reducer. The motor is provided with only a cable connection hole and a reducer output shaft hole; sealing devices are provided in the holes. A coniform water guide is provided between the water wheels, and takes an axis of rotation as the axle center. Leaf blades are connected to the exterior wall of the wheels; bottoms of the leaf blades overlap each other in turn. A transitional part having exterior margin in the shape of circular arc camber is embedded at the overlapped position. The leaf blades and the transitional part form a helicoid. The buoys are ring-shaped, and are enclosed around the water wheels; a space is reserved between the buoys. The utility model can spray output water upwards, and the water can be in boiled status in an area so that the contact area between the water and air during spraying of the water is significantly improved, and oxygen dissolved in the water is significantly improved due to the special structure of the water wheels. In addition, due to the completely closed structure and the type of cooling of the water cooled motor, performance life of the motor is significantly improved; the overall structure of the utility model is simple and compact; the cost is low.

Description

Water wheel type ventilator

Technical field

The utility model relates to technical field of aquaculture, especially relates to a kind of oxygen-increasing device of aquaculture water.

Background technology

Carry out the aquaculture of high-density industrial artificial in order to adapt at standing water, the inventor had once declared patents of invention such as eddy flow, aeration combined type automatic aerator and blade, aeration combined type automatic aerator successively, though such oxygenating machine will be got well than all kinds oxygenating machine effects such as existing vane type, water wheel type, water jet, water pump type, air-pump types, but because cost is too high, the raiser is difficult to accept, and popularization is had any problem; Use morely with paddle aerator in the above-mentioned prior art, its oxygenation effect is also better relatively; It is the rotation with the water lift impeller, by the water lift blade on the impeller water is left the water to cubic splash, with air mixed to increase the oxygen level in the water; Because its structure tube list, cost is low and obtain widespread use; But thisly increase and the air contact area with the globule that spills behind the water lift, foam, increase dissolved oxygen amount to cubic splash structure, make to propose water and become the water ratio of the globule, foam not high, therefore limited the raising of water body dissolved oxygen amount.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, the impeller that replaces the normal tape blade with water wheels is provided, making and proposing water is not to cubic splash, but upwards eruption, cause the boiling shape in certain zone, thereby improve greatly water in the eruption process with the contact area of air, thereby improve a kind of water wheel type ventilator of water body dissolved oxygen amount.

For achieving the above object, the technical solution adopted in the utility model is such: a kind of water wheel type ventilator, comprise motor, speed reduction unit, water wheels and floating drum, said motor is a water cooled machine, and itself and speed reduction unit link, and the two forms a full-closed structure, only be provided with the cable connecting hole in the upper end, be provided with the reducer output shaft hole in order to tie cable with in the lower end, be used for the attaching output shaft; Between output shaft hole and output shaft, and between leader cable connecting hole and cable, be equipped with tightness system; Output shaft is the water wheels rotating shaft, said water wheels, the centre is to be the conical guide water board in axle center with the rotating shaft, be connected with blade on its outer wall, the wheel rim projection of being made up of blade is a hexapetalous flower shape, each blade is overlapped successively mutually in the bottom, is embedded with the transition body that outer rim is circular arc camber at overlapping part, and blade and transition body form a spirochete; This spirochete and conical guide water board are one, have constituted water wheels; Said floating drum is annular, is fixed with anchor ear on it, and anchor ear and support link, and this support fixes with the obturator of being made up of motor and speed reduction unit, and this annular floating drum is set in outside the water wheels, leaves spacing between the two; During work, the water of executing body output through the water wheels spiral shell causes the boiling shape along upwards eruption between the inner ring wall of conical guide water board outer wall and annular floating drum in certain zone, simultaneously motor is cooled off.

Owing to adopted technique scheme, a kind of water wheel type ventilator of the present utility model, special construction because of water wheels, be the structure of one promptly by conical guide water board and spirochete, be in again in the annulus of annular floating drum, can make the upwards eruption of water of output, in certain zone, cause the boiling shape, make water in the eruption process, improve greatly, thereby the water body dissolved oxygen amount is improved with the contact area of air; Simultaneously the full-closed structure and the type of cooling of water cooled machine increase electrical machinery life greatly, and integral body to have a structure tube single, compact, lower-cost characteristics.
