[0002] When trying to achieve factory-scale recirculating aquaculture in the aquaculture field, the equilibrium concentration of dissolved oxygen in the water body must reach a dissolved oxygen requirement of more than 7%. Although there are oxygen cone devices of different sizes on the market, most of these devices come from the industrial field, and their working principle is to press oxygen into the water body through high pressure. However, the aquaculture environment is not suitable for the application of such high-pressure oxygen cone equipment. On the one hand, the pressure demand of aquaculture is much lower than that of industrial applications; on the other hand, the cost of manufacturing such high pressure is extremely high, which is not economical and practical for the aquaculture industry. Therefore, the existing industrial oxygen cones are directly used in aquaculture, which has the disadvantages of high cost and high energy consumption, and cannot achieve the expected effect.

[0022] Embodiment 1:

[0023] In this embodiment, a new type of oxygen cone, such as Figure 1As shown, it includes a shell 1, a water pump 2 and a venturi tube ejector 3. Specifically, the shell 1 is divided into a first mixing chamber 4 and a second mixing chamber 5 by a partition. The venturi tube ejector 3 is arranged in the second mixing chamber 5. The second mixing chamber 5 is provided with a dissolved oxygen water outlet 6, a pure oxygen air inlet 7 and a water inlet 8. The partition is provided with a connecting hole 9 and a drain hole 10. The water inlet end of the venturi tube ejector 3 is connected to the water inlet 8 and the water outlet end is connected to the connecting hole 9. The air inlet end of the venturi tube ejector 3 is connected to the pure oxygen air inlet 7. The water outlet end of the water pump 2 is connected to the water inlet 8 through a water pipe. When water passes through the venturi tube ejector 3, negative pressure can be formed in the pipe, thereby inhaling pure oxygen without additional power.

[0024] With this structure, water and pure oxygen are preliminarily mixed through the Venturi ejector 3 to form oxygenated water, which is then pumped to the first mixing chamber 4 and enters the second mixing chamber 5 through the drainage hole 10. The oxygenated water is fully mixed twice in the first mixing chamber 4 and the second mixing chamber 5 to ensure that oxygen is evenly mixed in the water. The flow rate of water is used to create an oxygen mixing effect without the need for high-pressure mixing, thereby achieving the purpose of low energy consumption and high dissolved oxygen, greatly reducing energy consumption and costs, and making the utility model more practical.

[0025] In this embodiment, Figure 1 As shown, the first mixing chamber 4 and the second mixing chamber 5 are arranged one above the other. With such arrangement, after the oxygenated water is mixed in the first mixing chamber 4, it can fall from the drainage hole 10 into the second mixing chamber 5 under the action of gravity, and secondary mixing can be performed during the falling process.

[0026] In this embodiment, Figure 1 As shown, the dissolved oxygen water outlet 6 is provided at a position near the partition on the upper part of the side wall of the second mixing bin 5. The position of the dissolved oxygen water outlet 6 is relatively high, so that the oxygenated water stays longer in the second mixing bin 5, and the mixing of oxygen and water is fully completed. Furthermore, the pure oxygen inlet 7 is provided at a position near the bottom of the lower part of the side wall of the second mixing bin 5, which is closer to the water inlet end of the venturi ejector 3, so that the incoming pure oxygen can be more fully mixed with the pumped water, thereby increasing the mixing time of pure oxygen and water in the venturi ejector 3 and improving the dissolved oxygen level.

[0027] Furthermore, the connecting hole 9 is opened at the center position of the partition, the drain hole 10 is arranged on one side of the connecting hole 9, the water inlet 8 is opened at the bottom center position of the second mixing chamber 5, and the venturi tube ejector 3 vertically connects the connecting hole 9 and the water inlet 8, so that pure oxygen and water are fully mixed in the venturi tube ejector 3.

[0028] As an optimized implementation of this embodiment, Figure 1 As shown, it also includes a spiral static mixer 11. The spiral static mixer 11 is a prior art. The spiral static mixer 11 is a tube with spiral blades fixed inside, so that a spiral flow channel is formed inside the tube, wherein the water inlet end of the spiral static mixer 11 is fixed on the partition through the drainage hole 10 and is connected with the first mixing chamber 4, and the water outlet end of the spiral static mixer 11 is suspended in the second mixing chamber 5. The oxygenated water in the first mixing chamber 4 flows into the spiral static mixer 11 under the action of gravity, and then flows to the second mixing chamber 5 in a spiral path in the spiral flow channel of the spiral static mixer 11, so that oxygen and water can be further mixed in the spiral static mixer 11, which helps water and oxygen to penetrate and mix more deeply and improve the dissolved oxygen level.

[0029] As an optimization, the number of the drainage holes 10 and the spiral static mixer 11 is multiple, and the multiple drainage holes 10 are evenly arranged along the circumference with the connecting hole 9 as the center. Multiple spiral static mixers 11 are arranged to improve the flow rate and dissolved oxygen efficiency.

[0030] In this embodiment, the shell 1 is a plastic part. Since high-pressure mixed oxygen is not required, the internal pressure of the shell 1 is relatively small. The use of plastic material effectively reduces the dead weight and cost, and is convenient for assembly and transportation.

[0031] In actual applications, a new 800-watt oxygen cone was used in 500 cubic meters of water, connected to a 10-ml small oxygen generator. Through such a configuration, the equilibrium concentration of dissolved oxygen in the water can be maintained above 7.5%. Compared with traditional industrial oxygen cones, it not only reduces energy consumption by more than 80%, but also greatly reduces the use of pure oxygen.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
