Underwater aeration oxygenation pump unit

Abstract

The invention discloses an underwater aeration oxygenation pump unit for aquaculture oxygenation. The underwater aeration oxygenation pump unit comprises at least two underwater aeration oxygenation pumps and a connecting frame, tail portions with water inlet of the underwater aeration oxygenation pumps are in a series connection through the connecting frame around a center point, directions of the water outlets of the underwater aeration oxygenation pumps outwards and radially radiate around the center point, a plurality of underwater aeration oxygenation pumps are centralized and connected together to spray water and air in deep water in a mixed radial mode, water flow sprayed under water helps a water layer to perform rotational motion, oxygen can be increased in deep water, simultaneously, the water layer flowing speed is increased, oxygenation effects in deep water are improved, oxygen bearing water can be further carried farther away, the oxygenation area is increased, the underwater aeration oxygenation pump unit is suitable for improved deep water breeding density, and installation project costs are low. Accordingly, the underwater aeration oxygenation pump unit has the advantages that the plurality of underwater aeration oxygenation pumps are installed together, the water layer flowing speed can be increased, the oxygenation effects in deep water can be improved, the breeding density is further increased, and installation project costs are further reduced.

Description

technical field [0001] The invention relates to a submersible aeration and oxygenation pump group for aquaculture oxygenation. Background technique [0002] In the aquaculture industry, the aeration pump is an essential aeration tool, which can greatly improve the quality and density of aquaculture, and is also an important means to increase economic benefits; in the prior art, the aeration method usually uses a submersible electric The pump pumps the water on the lower layer to the surface of the water and then forms a spray to spray the air into the air to absorb oxygen and then return to the water surface. The ordinary aeration pump is basically this type. This oxygenation method is only one layer of the water surface, which is insufficient for deep-water aquaculture. The aquaculture density The improvement is not much. At the same time, the aeration pump is usually installed independently.

[0002] In the aquaculture industry, the aeration pump is an essential aeration tool, which can greatly improve the quality and density of aquaculture, and is also an important means to increase economic benefits; in the prior art, the aeration method usually uses a submersible electric The pump pumps the water on the lower layer to the surface of the water and then forms a spray to spray the air into the air to absorb oxygen and then return to the water surface. The ordinary aeration pump is basically this type. This oxygenation method is only one layer of the water surface, which is insufficient for deep-water aquaculture. The aquaculture density The improvement is not much. At the same time, the aeration pump is usually installed independently. If the breeding area is large, multiple aeration pumps must be installed separately to meet the oxygen density requirements. They cannot be installed together to facilitate the increase of the flow of the water layer. The speed and oxygenation effect and the reduction of installation engineering cost make the installation engineering workload larger and the cost higher. At the same time, its structure does not allow them to be connected together. Therefore, an oxygenation pump that can increase oxygenation in deep water is needed. Further While expanding the breeding density, it is a technical problem that needs to be solved at present to install multiple units together to increase the flow rate and oxygenation effect of the water layer and reduce the cost of installation projects.
