Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0031] The following refers to Figures 1 to 3 Describe an aerator for mixing air, oxygen and liquid according to an embodiment of the present invention.

[0032] As Figure 1As shown in the figure, an aerator for mixing air, oxygen and liquid according to an embodiment of the present invention includes a housing 100, a driving mechanism and an oxygen delivery component. The housing 100 is provided with a water inlet 101 and a water outlet 102. The driving mechanism includes a driving unit 210 provided in the housing 100, a transmission shaft 220 connected to the driving unit 210, and an impeller 230 provided on the transmission shaft 220. The impeller 230 can drive the fluid to be output from the water inlet 101 to the housing 100 and sent out from the water outlet 102. The transmission shaft 220 is a hollow shaft, and the transmission shaft 220 is provided with an air inlet 221 and an air outlet 222 connected to its inner cavity. The air outlet 222 is located at a position corresponding to the impeller 230 or on the path of the fluid flow. The oxygen delivery component is provided in the housing 100, and the oxygen outlet of the oxygen delivery component is located at a position corresponding to the impeller 230 or on the path of the fluid flow.

[0033] During operation, when the impeller 230 drives the water to flow, a negative pressure can be formed at the air outlet 222, so as to suck the external air from the air inlet 221, so that the air is continuously sucked from the air inlet 221, discharged from the air outlet 222 and mixed with the water flow, thereby increasing the dissolved oxygen content. At the same time, the oxygen delivery component can deliver oxygen to be mixed with the water flow to further increase the dissolved oxygen content, and the air, oxygen and water are fully mixed, thereby greatly improving the dissolved oxygen content of the water body.

[0034] In some embodiments of the present invention, the water flow generated by the impeller 230 is output from the water outlet 102, and by controlling the direction of the water outlet 102, the delivery direction of the water flow with high oxygen content can be guided, such as being delivered to the bottom of the water to increase the oxygen content of the lower layer of the water, or being delivered to the middle layer or the upper layer of the water according to needs.

[0035] Specifically, as Figure 1 shown, the housing 100 has a long cylindrical structure, the water outlet 102 is located at the lower end of the housing 100, and the housing 100 is provided on a floating body such as a ship or a floating ball. By changing the direction of the housing 100, the water layer of the water flow with high oxygen content output can be adjusted.

[0036] In some embodiments of the present invention, the aerator is provided on the hull, and the hull is configured with a support mechanism capable of supporting the housing 100, and the support mechanism can adjust the orientation of the housing 100, so as to adjust the spraying direction of the water flow.

[0037] In some embodiments of the present invention, the water outlet 102 faces the bottom of the water, which can increase the oxygen content of the bottom layer of the water and can scour the sediment at the bottom layer of the water to avoid forming a dead corner for cleaning.

[0038] Such as Figure 1As shown, in some embodiments of the present utility model, the air inlet 221 is provided at the upper end of the transmission shaft 220, the air outlet 222 is provided at the lower end of the transmission shaft 220, the impeller 230 is an axial flow impeller, and the water flow generated by the impeller 230 flows axially and passes through the air outlet 222, thereby forming a negative pressure at the air outlet 222, and continuously sucking external air from the air inlet 221 by using the negative pressure.

[0039] Specifically, the axial flow impeller can generate a fluid with an axial rotational flow, so as to achieve a better mixing effect with air and oxygen, improve the dissolved oxygen rate. At the same time, the fluid with an axial rotational flow has better directivity, can push the water body with high dissolved oxygen to the specified water layer, and can generate a large flow effect, so that oxygen can be evenly distributed throughout the pool, and at the same time can accelerate the water body circulation and improve the effect of cleaning and purifying water quality.

[0040] In some embodiments of the present utility model, the air outlet direction of the air outlet 222 is the same as the water flow direction, so that an air suction structure similar to the chimney effect can be easily formed to suck the air in the transmission shaft 220.

[0041] In some embodiments of the present utility model, the transmission shaft 220 is a hollow shaft, which can directly transport air to the axial flow direction of the impeller 230. This can not only simplify the structure, reduce the air pipes, make the mechanism more compact and reasonable, but also have higher air suction efficiency and water-air mixing efficiency.

[0042] It can be understood that, in some embodiments of the present utility model, the air outlet 222 can also be arranged at the installation position of the impeller 230, and the air output through the air outlet 222 can be directly stirred by the impeller 230, having a better dissolved oxygen effect.

[0043] As Figure 1 shown, in some embodiments of the present utility model, the transmission shaft 220 is provided with an active air suction mechanism 240. The active air suction mechanism includes several blades arranged at the air inlet 221. The transmission shaft 220 can drive the blades to rotate, and when the blades rotate, they can suck external air into the air inlet 221, thereby increasing the air intake volume of the air inlet 221 and improving the dissolved oxygen amount of the water body.

[0044] Specifically, the blades are centrifugal blades, and a plurality of blades are distributed around the transmission shaft 220. When the transmission shaft 220 rotates, it drives the plurality of blades to rotate, thereby sucking external air into the transmission shaft 220.

[0045] As Figure 1 shown, in some embodiments of the present utility model, the housing 100 has a long cylindrical structure, the transmission shaft 220 is arranged in the housing 100, and the housing 100 is provided with an air intake passage 103.

[0046] As Figure 1As shown, in some embodiments of the present utility model, the driving unit 210 is a motor, which is connected to the transmission shaft 220 through a coupling or the like.

[0047] As Figure 1 shown, in some embodiments of the present utility model, the lower part of the housing 100 is provided with a water inlet section 110. The water inlet section 110 is provided with a plurality of water inlet holes 101. The impeller 230 is arranged in the water inlet section 110. The impeller 230 sucks external water (low oxygen content) from the water inlet holes 101, and then sends it out from the water outlet 102 and mixes it with oxygen and air.

[0048] Specifically, the water inlet section 110 is a relatively large barrel structure, densely distributed with water inlet holes 101. The water inlet holes 101 are of a microporous structure to achieve the effect of filtering foreign matters.

[0049] As Figure 1 shown, in some embodiments of the present utility model, the oxygen delivery component includes an oxygen delivery pipe 310 and a nano oxygenation pipe 320 connected to the oxygen delivery pipe 310. The micropores of the nano oxygenation pipe 320 form oxygen outlets, and the micropores of the nano oxygenation pipe 320 are used to achieve a better oxygen dissolution effect.

[0050] It can be understood that, in some embodiments of the present utility model, the nano oxygenation pipe 320 can also be replaced by a high-density air stone or the like, which will not be elaborated herein.

[0051] As Figure 1 shown, in some embodiments of the present utility model, the lower end of the housing 100 is provided with a water outlet 102. The water outlet 102 is provided with a diversion pipe 400. The nano oxygenation pipe 320 is arranged in the diversion pipe 400. The diversion pipe 400 is used to guide the water flow direction and provide a space for mixing water, oxygen and air, forming a gas-liquid mixing cavity. After the water, oxygen and air are fully dissolved in the diversion pipe 400, they are finally discharged from the outlet of the diversion pipe 400.

[0052] It can be understood that, in some embodiments of the present utility model, the nano oxygenation pipe 320 can also be arranged at other positions in the water flow path, such as arranged in the water inlet section 110, arranged at the air outlet 222, etc., and all can achieve a better oxygen dissolution effect.

[0053] As Figure 1 、 Figure 3 shown, in some embodiments of the present utility model, an oxygen dissolution cavity 401 is annularly arranged on the outer wall of the diversion pipe 400. The nano oxygenation pipe 320 is annularly arranged in the oxygen dissolution cavity 401. A communication hole 402 is arranged between the oxygen dissolution cavity 401 and the inner wall of the diversion pipe 400, so that the oxygen generated by the nano oxygenation pipe 320 can enter the diversion pipe 400 to form contact with the water flow.

[0054] It can be understood that in some embodiments of the present utility model, the nano-aeration tube 320 can also be directly disposed in the diversion tube 400, and a good dissolved oxygen effect can also be achieved.

[0055] In some embodiments of the present utility model, the nano-aeration tubes 320 are at least configured in two groups to achieve a good dissolved oxygen effect.

[0056] As Figure 2 、 Figure 3 shown, in some embodiments of the present utility model, all the nano-aeration tubes 320 are connected through connectors 330 and connected to the oxygen delivery tube 310 through the connectors 330 to facilitate wiring.

[0057] It can be understood that in some embodiments of the present utility model, independent air distribution or an independent on-off valve can also be configured for each nano-aeration tube 320 to achieve different dissolved oxygen effects.

[0058] As Figure 2 、 Figure 3 shown, in some embodiments of the present utility model, an outer shell 410 is annularly arranged on the outer wall of the diversion tube 400, and a dissolved oxygen cavity 401 is formed between the inner wall of the outer shell 410 and the outer wall of the diversion tube 400. The outer shell 410 is detachably connected to the diversion tube 400 to facilitate the cleaning and maintenance of the dissolved oxygen cavity 401, and it is also convenient to clean or replace the nano-aeration tube 320.

[0059] In some embodiments of the present utility model, the outer shell 410 is provided with a detachable structure capable of opening the dissolved oxygen cavity 401. For example, the outer shell 410 is composed of multiple components, and at least some components can be independently disassembled and installed, so as to meet the cleaning and maintenance requirements of the dissolved oxygen cavity 401.

[0060] In some embodiments of the present utility model, a high-speed motor drives a hollow transmission shaft via a connector (with blades provided), synchronously driving the end axial flow impeller to push the water body. At this time, the hollow transmission shaft will form a negative pressure inside the tube because the air in the shaft is carried away by the water flow. Meanwhile, the atmospheric pressure quickly enters the shaft, and the huge suction force generated sucks the air through the air inlet, blades, transmission shaft, and impeller. Finally, in the gas-liquid mixing cavity, the gas-liquid is stirred and mixed to form high-dissolved-oxygen water, which is then pushed to the whole pool by the strong water flow, evenly distributed throughout the pool, and pure oxygen is sent into the gas-liquid mixing cavity through a nano-tube. The pure oxygen outputs tiny oxygen bubbles through the nano-tube, further increasing the oxygen content in the water.

[0061] When the aerator is running, it can push the water flow to the bottom of the pond, squeeze the bottom water to flow and bring up the dirt to rise with the water flow for aeration. During the operation process, air and oxygen will form a gas-liquid mixture with the water liquid in the impeller and the mixing cavity pipe to form a high-dissolved oxygen water flow, which can push the bottom water to run to the whole pond, completely solving the problem of water body stratification in aquaculture. The strong water flow can make the water body of the whole pond circulate without dead corners of dissolved oxygen. The water flow of this machine is so strong that it can reach more than 100 meters. The continuous operation of a single machine can make the water of a ten-acre fish pond circulate throughout the pond.

[0062] Moreover, harmful substances such as fish feces, residual bait, ammonia nitrogen, and nitrite at the bottom of the pond will be turned out of the water surface with the water flow to contact with the atmosphere and sunlight for aeration decomposition. At the same time, with the drive of the water flow, the dirt will be pushed to the sewage outlet, making it easier for sewage cleaning.

[0063] Of course, the creation of the present utility model is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without violating the spirit of the present utility model. These equivalent variations or substitutions are all included in the scope defined by the claims of this application.
