[0018] Compared with the prior art, this utility model has the following advantages:
[0019] This utility model provides an oxygen cone and recirculating aquaculture device, including a shell, an ejector, a static oxygen mixing and cutting device, and a water pump; wherein: the shell is provided with a first cavity, a mixing cavity, and a second cavity that are independent of each other; the second cavity has a shell inlet on its wall, and the first cavity has a shell outlet on its wall; the ejector's inlet is connected to the shell inlet, and the ejector's outlet is connected to the second cavity; the static oxygen mixing and cutting device's inlet and outlet are respectively connected to the second cavity and the mixing cavity; the water pump's inlet and outlet are respectively connected to the mixing cavity and the second cavity.

The oxygen-enriched water after this second round of mixing enters a water pump for a third round of mixing, resulting in the oxygen-enriched water being ejected from the first chamber through the outlet. Power is provided solely by the water pump, improving energy utilization and reducing energy consumption. The triple oxygen mixing process—using the ejector, static oxygen mixing and cutting device, and water pump—ensures a uniform dissolved oxygen content in the water. Attached Figure Description

[0027] Example 1:
[0028] An oxygen cone and recirculating aquaculture system includes a shell 1, an ejector 2, a static oxygen mixing and cutting device, and a water pump 3; wherein:
[0029] The outer shell 1 is provided with an independent first cavity 4, a mixing cavity and a second cavity 5. The second cavity 5 is provided with an outer shell water inlet 8 on its cavity wall and the first cavity 4 is provided with an outer shell water outlet on its cavity wall. The water inlet of the jet injector 2 is connected to the outer shell water inlet 8 and the water outlet of the jet injector 2 is connected to the second cavity 5.
[0030] The inlet and outlet of the aforementioned static oxygen mixing cutting device are respectively connected to the aforementioned second cavity 5 and the aforementioned mixing cavity;
[0031] The inlet and outlet of the water pump 3 are connected to the mixing chamber and the second chamber 5, respectively.
[0032] In the above structure, the jet injector 2 mixes the incoming water flow with oxygen through the inlet to form oxygen-enriched water. The oxygen-enriched water is then subjected to secondary oxygen mixing and cutting by the static oxygen mixing and cutting device in the first chamber 4, which refines the oxygen bubbles and improves the dissolution efficiency. The oxygen-enriched water after secondary oxygen mixing and cutting enters the water pump 3 for a third cutting, and the oxygen-enriched water after three cuttings is sprayed out from the outlet 9 through the first chamber 4. Power can be provided by the water pump alone, which improves energy utilization and has low energy consumption. The triple cutting of dissolved oxygen by the jet injector, the static oxygen mixing and cutting device, and the water pump makes the dissolved oxygen content of the water uniform.
[0033] The aforementioned mixing chamber includes two independent chambers, a third chamber 6 and a fourth chamber 7. The aforementioned static oxygen mixing cutting device includes a first rubber core spiral rod and a second rubber core spiral rod, wherein:
[0034] The inlet and outlet of the first core spiral rod are connected to the second cavity 5 and the third cavity 6, respectively. The inlet and outlet of the second core spiral rod are connected to the third cavity 6 and the fourth cavity 7, respectively. The inlet of the water pump 3 is connected to the fourth cavity 7. By separately arranging the first core spiral rod 10 and the second core spiral rod 11 within the first cavity 4, the second cavity 5, and the third cavity 6, the water flow path is longer, allowing for a longer and more thorough secondary cutting and oxygenation process. The core spiral rod is a mechanical device combining a spiral structure and a core design, primarily used in fluid mixing, colloid control, or precision dispensing scenarios. Its core function is to achieve colloid delivery, mixing, or precise extrusion through spiral motion.
[0035] The number of the first rubber core spiral rods is two or more, and the number of the second rubber core spiral rods is two or more.
[0036] The aforementioned outer shell 1 is constructed of a sealed corrosion-resistant plate. The outer shell 1 is designed as a sealed corrosion-resistant plate to protect the internal jet injector 2, static oxygen mixing cutting device, and water pump 3 from water corrosion.
[0037] The first cavity 4, the second cavity 5, the third cavity 6, and the fourth cavity 7 mentioned above are all closed cavities. The closed cavities allow for sufficient oxygenation of the water inside, and the water in each cavity can only be transferred through the jet injector 2, the static oxygenation cutting device, and the water pump 3.
[0038] Water flows from the inlet 8 of the outer casing, through the main body of the jet injector 2, into the fourth chamber 7, then through the first rubber core spiral rod 10 into the third chamber 6, then through the second rubber core spiral rod 11 into the second chamber 5, then through the water pump 3 into the first chamber 4, and finally out through the outlet 9. The high-speed impeller of the water pump 3 performs a third cutting and oxygenation of the water, and provides power. The oxygen-enriched water discharged from the outlet 9 drives the pool water to rotate, promoting water circulation; and by using only the water pump 3 as power, the energy utilization rate is improved.
[0039] The aforementioned water outlet 9 is located at the upper end of the aforementioned first cavity 4. This makes the water circulation channel longer, allowing the water in the first cavity 4 to be fully oxygenated before flowing out from the upper outlet 9.
[0040] The aforementioned water inlet 8 is located at the lower end of the aforementioned fourth cavity 7. The location of the water inlet 8 at the lower end of the fourth cavity 7 makes the water circulation channel longer.
[0041] The outer wall of the aforementioned housing 1 is provided with a slide rail plate 12, which is connected to an adjustable hook 13. The slide rail plate 12 and the hook 13 enable the oxygen cone and recirculating aquaculture device to adapt to different water levels and facilitate installation and disassembly.
[0042] It also includes a protective cover, which is a stainless steel mesh, and is fitted onto the outer shell 1. The stainless steel mesh fitted onto the outer shell 1 prevents debris from entering the oxygen cone and recirculating aquaculture system, thus ensuring the safe operation of the internal equipment of the oxygen cone and recirculating aquaculture system.
[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
