Surge type oxygenation device for breeding pond

Abstract

The invention discloses a surge type oxygenation device for a breeding pond. The surge type oxygenation device comprises an axial flow pump and a jet pipe connected to the outlet end of the axle flow pump. The sidewall of the upper portion of the jet pipe is connected with an air inlet pipe extending out of the water surface. An eddy current structure for enabling water to form an eddy current is arranged at the joint between the interior of the jet pipe and the axle flow pump. A water and air mixing component for enabling water and air to be mixed fully is arranged in the jet pipe and located at a connector of the air inlet pipe. The axle flow pump works and sucks the water in the pond, pressurizes the water and sprays the water out of the jet pipe. Negative pressure will be formed at the joint between high-speed water flow and the air inlet pipe. Under the action of atmospheric pressure, external air enters the jet pipe through the air inlet pipe, the air and the water are mixed and diffused, and the oxygen content of the water is increased; meanwhile, the water and air mixing component can evenly distribute the air entering the jet pipe through the air inlet pipe so that the air and the water can be mixed more fully, the content of the air blended into the water can be greatly increased, and therefore the oxygenation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water body oxygenation equipment in aquaculture system, in particular to a surge type aeration device for aquaculture ponds. Background technique [0002] In the aquaculture industry, the oxygen content of the water body is a key indicator for safe farming. At present, there are two commonly used aeration devices in aquaculture ponds: one is the impeller type or waterwheel type aeration device, which mainly drives the impeller to rotate through the motor, raises waves on the water surface, and throws the water body to In the air, disperse, and drop after full contact with the air to achieve the purpose of increasing oxygen in the pond water. This kind of oxygenation device usually only increases oxygenation for surface water bodies, and it is difficult to fully oxygenate deeper water layers, and the oxygenation effect is poor. [0003] The other is an oxygenation type aeration device, which mainly abso...

Problems solved by technology

However, this oxygenation method has certain limitations: since the air is pressurized and sprayed into the water, the air bubbles formed are relatively large, so the air incorporated into the water is small, and the oxygenation effect is not good; and this oxygenation method is affected by The depth of the water body is limited. As the depth of the water body increases, the fewer air bubbles are generated, and the degree of contact between the air and the water body is limited.
