Impeller type aerator for increasing aeration quantities

Abstract

The invention relates to the technical field of fishery breeding equipment, and discloses an impeller type aerator for increasing aeration quantities. The impeller type aerator comprises a main body,the outer side of the main body is fixedly connected with three connecting rods, and the other ends of the three connecting rods are fixedly connected with floating balls. Through arranging a piston ring and a rotating device, when the aerator is working, an upper rotating main body rotates, and spiral vanes rotate synchronously, thus driving guide rods to move downwards along the upper surfaces of the spiral blades, making the piston ring move downwards and pressing air inside the main body down to eject from through-holes, so that the air directly enters deep water body to be combined with the water to increase the oxygen content of the water body. When the guide rods move to the bottom ends of the spiral blades, because the spiral blades are in half spiral structure, the piston ring andthe guide rods are brought to the upper ends of the spiral blades under the action of a return spring, so that the piston ring can continuously move up and down during the rotation of a double-shaftmotor, thus continuously pressing the air into the water body below and continuously increasing the oxygen content of the water body.

Description

technical field [0001] The invention relates to the technical field of fishery breeding equipment, in particular to an impeller-type aerator for increasing the amount of oxygen added. Background technique [0002] The impeller type aerator can meet the oxygen supply demand of a large area of ​​ponds, increase the dissolved oxygen in water, improve the water quality, and improve the economic benefits of aquaculture. It is mainly composed of a motor, a water surface impeller and a floating ball. The impeller type aerator is powered by The device drives the impeller to rotate in the water body, so that the water is drawn out of the water surface and sprinkled into the air, so that the water droplets can fully contact with the oxygen in the air to achieve the purpose of increasing the dissolved oxygen of the water droplets falling back into the water body; at the same time, the water at the bottom will flow upwards. The flow replenishes the upper layer water that has been drawn ...

AI Technical Summary

Problems solved by technology

[0003] However, the current impeller-type aerator still has the following deficiencies in the actual use process: first, the water body can only achieve the purpose of increasing oxygen by being raised by the impeller to increase contact with the air, and the oxygen dissolved in the water body is limited, which is difficult to meet the needs of ponds. The demand for increasing production of aquaculture; secondly, the impeller aerator can only extract water at a fixed depth in the water body. At this time, the impeller type aerator can only increase oxygen in the shallow water body, but cannot increase the oxygen in the deep water body, resulting in a low oxygenation efficiency of the wind wheel type aerator, and it is still prone to high-yield floating head hypoxia. fish mass die
