The realization of the present invention is more obvious than the oxygenation effect of the traditional machine under the condition of the output power equivalent, and the water can be increased more rapidly. The amount of dissolved oxygen ensures the survival conditions of aquatic products, reduces the cost of breeding, increases the density of culture, and increases the practical effect of good water lifting effect.

In the 1970s, due to limited technology, the yield increase of pond fish farming encountered bottlenecks, mainly due to the lack of oxygen in the pond water body. At that time, the conventional aeration equipment could not meet the demand, and could not be solved due to the high yield of floating head hypoxia. In this context, a large number of fish death problems have been developed. In the current water treatment equipment for aquaculture, due to regional conditions, farmed fish species and other factors, many farmers use traditional impellers. The type of aerator, the traditional impeller aerator has a small effect of lifting water, a small push flow range, and a weak oxygen-increasing effect. When actually used, the structural design of the traditional impeller aerator is not able to do more depending on environmental changes. The use of performance changes, the practicality is significantly worse.

At the bottom, the water-repellent plate 3 is located on the impeller body 1, the water-passing hole 4 is located on the water-repellent plate 3, the guide rib 5 is located outside the water-repellent plate 3, and the shape of the water-repellent plate 3 is curved, and several water-repellent plates are provided. Tilting in the direction of rotation, the reduction ratio of the reducer 12 is 10:1, the outer diameter of the impeller 14 is φ660 mm, the rotation speed of the impeller 14 is about 140 r/min, and the rotation direction is right-handed; the depth of the draft of the impeller 14 is two and a half. The height of the pumping water generated by the machine can jump over three floats, reducing the resistance of the float to the water flow, and forming an oxygen-rich circle with a radius of about ten meters centered on the aerator.

This creation uses a water deflector 3 to rotate water and water to make the formed water flow parabolically spread. Open, so that the raised water body is higher and farther; the water passing hole 4 can reduce the resistance when the machine is turned on, and the guiding rib 5 has the function of shredded water of the broken water function, so that the raised water flower is crushed to form finer water. The bead is used to increase the surface area in contact with the air to produce a high-efficiency water-dissolving effect, which makes the oxygen-enhancing ability stronger. The impeller body 1 adopts a hollow volume structure, which is injection-molded and directly spliced and welded with the bottom cover.

The impeller 14 has a rotational speed of 103 r/min to 160 r/min, a swing diameter of 400 mm to 1000 mm, and a water deflector 3 height of 150 mm to 300 mm.

The creation has the following characteristics: First, the impeller 14 of the present invention has its own buoyancy, and the water-repellent plate 3 has an impeller aerator for guiding the water and pulverizing the water body, and the output of the impeller 14 is connected to the rotation of the floating impeller 14 due to the floating body. The impeller 14 simultaneously reduces the volume of the three supporting floats; second, the creation enables the rapid transfer of oxygen in the air to the equipment in the aquaculture water body, the manufacture of the water body circulation, the promotion of convective exchange of water bodies, and the improvement of water quality conditions to achieve the desired oxygenation target. And save costs and improve efficiency; Third, the impeller 14 of this creation replaces the impeller of the traditional impeller aerator, the performance index of the oxygenation effect is not lower than its standard requirements; Fourth, compared with the traditional impeller aerator The effect of the loop water flow generated by the operation of the impeller 14 of the present invention exceeds the water flow generated by the impeller of the impeller aerator of the same supporting power, and the economic benefit of more than 15% can be saved.
