Detailed Description

The present invention will be further described with reference to fig. 1-2.

The oxygenation devices used in the current market generally comprise impeller type oxygenators, jet type oxygenators and the like, air is sucked into water during oxygenation work to achieve the purpose of oxygenation, but the instruments are often large in size and large in power consumption, and the problems that the oxygenation effect is not ideal due to the fact that the power consumption and the size are reduced are solved.

Therefore the utility model provides an oxygenation pump, including water pump interface 8 and delivery port 1, be equipped with the oxygenation structure between water pump interface 8 and the delivery port 1, the oxygenation structure includes air mouth 5, ejector 7 and mixing flow room 4, inhales the air in the air mouth 5, and rivers pass through ejector 7 with higher speed and the air is in mixing flow room 4 mixes, and mixing flow room 4 is connected with 7 one end of ejector, and mixing flow room 4 internal diameter is from keeping away from 7 one end of ejector to being close to 7 one end distances of ejector and crescent.

More specifically, the utility model discloses 5 perpendicular to ejectors 7 in cavity gas port are equipped with suction chamber 6 between air mouth 5 and the ejector 7, suction chamber 6 communicates with each other with air mouth 5, be equipped with diffusion tube 2 between mixed flow chamber 4 and the export, 2 internal diameters of diffusion tube reduce to 4 one ends in mixed flow chamber from export one end gradually, be equipped with choke 3 between diffusion tube 2 and the mixed flow chamber 4, choke 3 help mixed flow chamber 4 fixed diffusion tubes 2, wherein diffusion tube 2 all is favorable to increasing the negative pressure for conical design with mixed flow chamber 4, increase water pressure.

Further, the utility model discloses the theory of operation as follows: a water pump interface 8 of the oxygenation pump is connected with a water source, a water body is sprayed out through a nozzle of a jet device 7 to form a high-speed jet flow, the high-speed jet flow has an entrainment effect, so that gas around the jet flow is entrained into the jet flow, the suction chamber 6 is vacuumized due to pressure reduction, the outside air enters the suction chamber 6 from the air suction pipe under the action of atmospheric pressure, the outside air is continuously sucked, the gas entrained by the high-speed jet flow enters the throat pipe 3, is impacted and divided into countless micro bubbles by water flow, the water flow is mixed through the flow mixing chamber 4, the water flow and the steam are mutually transmitted and exchanged due to large speed difference of the two speeds, water emulsion is formed by collision and flow mixing, countless micro bubbles are formed after air impact, the absorption rate of oxygen is favorably improved, the gas in the throat pipe 3 is sprayed out through the diffusion pipe 2 after the liquid is mixed, and the sprayed out mixed liquid is a high-dissolved oxygen fluid, the dissolved oxygen of the pond water is promoted to be rapidly increased, water flow can be fully utilized, the water body is stirred, the dissolved oxygen of the surface water body can be rapidly increased in a short time, the water body is slowly oxygenated, species are ensured to survive, and death is reduced.

The utility model discloses need not with the help of any other equipment, only need provide service environment's immersible pump can, be connected it with the immersible pump, rivers are breathed in with efflux mode negative pressure, increase the mechanical oxygenation equipment of dissolved oxygen in the water, and oxygenation efficiency is far away super waterwheel is, inflatable, the oxygen-increasing machine of forms such as water spray formula, its simple structure, the cost is the second, the consumption is little, and oxygenation is efficient, light.
