Description

TECHNICAL FIELD

In the operation process of the oxygen cone, the circulating water flows from top to bottom, forming a large flow rate at the top of the cone, a small pressure on the bubble; the flow rate is small at the middle and lower parts of the cone, and the pressure on the bubble is large, and the bubble floats upwards. According to the principle of fluid mechanics, the pressure of the fluid decreases with the increase of the flow rate, so that the bubble is suspended above the cone. The bubble fluctuates above the cone until it is completely dissolved, increasing the water-gas exchange time, and achieving the purpose of forced oxygenation.

[0075] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0076] In some embodiments of this application, a recirculating aquaculture oxygen cone system is disclosed, comprising an oxygen cone to increase the dissolved oxygen content in the aquaculture water. To further increase the dissolved oxygen content in the aquaculture water, the water-air exchange time can be extended.

[0077] In some embodiments of this application, such as Figure 1 , Figure 2 As shown, the oxygen cone includes an oxygen cone body 110, and a receiving portion 111 is formed inside the oxygen cone body 110. The receiving portion 111 is used to hold aquaculture water and oxygen.

[0078] An inlet 112 is formed at the upper end of the oxygen cone body 110. An outlet 113 is formed at the lower end of the oxygen cone body 110. Aquaculture water flows into the oxygen cone body 110 through the inlet 112, and aquaculture water in the oxygen cone body 110 flows out of the oxygen cone body 110 through the outlet 113.

[0079] In some embodiments of this application, in order to improve the mixing of aquaculture water and oxygen within the oxygen cone body 110 and increase the dissolved oxygen rate in the aquaculture water, irregular flow is formed within the oxygen cone body 110, creating turbulence, thereby allowing oxygen and water to mix fully, enabling oxygen to dissolve better in the water, and increasing oxygenation efficiency.

[0080] Therefore, in some embodiments of this application, a first water flow path and a second water flow path are formed within the receiving portion 111. The first and second water flow paths form a merging portion within the receiving portion 111, where they flow in opposite directions, which can further increase the solubility of oxygen in water.

[0081] In some embodiments of this application, the first water flow path extends downward from the inlet 112 to the bottom of the receiving portion 111.

[0082] In some embodiments of this application, the second water flow path extends upward from the bottom of the receiving portion 111 to the outlet 113.

[0083] Therefore, within the receiving section 111, there is a reverse merging portion between the first water flow path and the second water flow path.

[0084] In some embodiments of this application, in order to enable the first water flow path and the second water flow path to converge in direction within the receiving portion 111, the oxygen cone further includes an isolation portion 120. The isolation portion 120 extends and is disposed in the lower part of the receiving portion 111, and an inlet portion 121 and an outlet portion 122 are formed on the isolation portion 120.

[0085] The water outlet 122 is connected to the water outlet 113.

[0086] The water inlet 121 is opened on the isolation section 120 in the direction of the bottom of the oxygen cone.

[0087] Specifically, the water inlet 121 is located on the lower surface of the isolation section 120.

[0088] As the first water flow path flows downward from the inlet 112, it passes through the area enclosed between the oxygen cone body 110 and the isolation section 120, and reaches the bottom of the receiving section 111.

[0089] The second water flow path starts from the bottom of the receiving part 111 and goes upward through the inlet part 121 into the isolation part 120, and then flows out of the isolation part 120 from the outlet part 122. Since the outlet part 122 is connected to the outlet 113, the water flows out through the outlet 113.

[0090] In some embodiments of this application, the isolation section 120 includes a perforated tube.

[0091] One end of the perforated tube is sealed to the inner wall of the oxygen cone body 110, and the water outlet 122 is a first through hole formed at the other end of the perforated tube.

[0092] The water inlet 121 consists of several second through holes formed on the lower wall of the perforated tube.

[0093] A receiving cavity is formed inside the perforated tube, and the water inlet 121 and the water outlet 122 are connected through the receiving cavity.

[0094] The first through hole is connected to the outlet 113.

[0095] Specifically, the second through holes are spaced apart along the length of the tube.

[0096] The perforated tube extends horizontally and is provided at the lower part of the receiving part 111.

[0097] In some embodiments of this application, such as Figure 3 As shown, an oxygen delivery unit and a control unit are also provided. The control unit can adjust the amount of oxygen delivered into the oxygen cone through the oxygen delivery unit.

[0098] The control unit includes a controller 310 and a detection component 320. The detection component 320 is electrically connected to the controller 310. The controller 310 is used to control the start and stop of the detection component 320.

[0099] The detection component 320 is used to detect the dissolved oxygen content at the outlet 113.

[0100] Specifically, the detection component 320 can use a dissolved oxygen probe to detect the dissolved oxygen content. The controller 310 uses the dissolved oxygen content detected by the detection component 320 to automatically adjust the amount of oxygen supplied from the oxygen delivery unit to the oxygen cone.

[0101] Specifically, the detection component 320 is used to detect the oxygen content at the end of the water outlet section 122.

[0102] In some embodiments of this application, such as Figure 4 As shown, the oxygen delivery unit includes an oxygen distribution section 210. The oxygen distribution section 210 includes a main oxygenation branch 211 and an auxiliary oxygenation branch 212.

[0103] When the liquid level in the oxygen cone body 110 is lower than the set lower limit value, the main oxygenation branch 211 is disconnected from the oxygen cone, and the auxiliary oxygenation branch 212 is connected to the oxygen cone.

[0104] When the liquid level in the oxygen cone body 110 reaches the set lower limit value, the main oxygenation branch 211 is connected to the oxygen cone, and the auxiliary oxygenation branch 212 is connected to the oxygen cone.

[0105] In order to detect the liquid level inside the oxygen cone body 110 and determine whether the liquid level inside the oxygen cone body 110 has reached the set lower limit value, thereby controlling the opening and closing of the main oxygenation branch 211, the oxygen cone also includes a liquid level detection component 130. The liquid level detection component 130 is used to detect the liquid level inside the oxygen cone body 110.

[0106] Specifically, the liquid level detection component 130 is electrically connected to the control unit. This allows the detected liquid level signal within the oxygen cone body 110 to be fed back to the control unit, which then controls whether the main oxygenation branch 211 supplies oxygen to the oxygen cone.

[0107] In some embodiments of this application, a main oxygenation control solenoid valve 2111 and a manual valve 2112 are connected to the main oxygenation branch 211.

[0108] The main oxygenation control solenoid valve 2111 and the manual valve 2112 are connected in parallel.

[0109] The main oxygenation control solenoid valve 2111 is electrically connected to the control unit. The control unit receives the detection signal from the liquid level detection component 130. When the control unit receives feedback from the liquid level detection component 130 that the liquid level in the oxygen cone has reached or exceeded the lower limit value, the control unit controls the main oxygenation control solenoid valve 2111 to turn on. In this state, both the main oxygenation branch 211 and the auxiliary oxygenation branch 212 are connected and simultaneously supply oxygen into the oxygen cone.

[0110] Manual valve 2112 is used for manual emergency operation in emergency situations.

[0111] Specifically, a first flow meter 2113 is connected in the main oxygenation branch 211.

[0112] A second flow meter 2121 is connected in the auxiliary oxygenation branch 212.

[0113] The first flow meter 2113 is used to detect the flow rate of oxygen in the main oxygenation branch 211.

[0114] The second flow meter 2121 is used to detect the flow rate of oxygen in the auxiliary oxygenation branch 212.

[0115] The control unit can adjust the oxygen delivery of the main oxygenation branch 211 and the auxiliary oxygenation branch 212 based on the data from the first flow meter 2113 and the second flow meter 2121.

[0116] This allows for precise control of the amount of oxygen supplied, preventing oxygen waste and underutilization of the oxygen cone's function.

[0117] In some embodiments of this application, a water conveyance circuit is also included. The water conveyance circuit includes an aquaculture tank 410, an inlet passage 420, and an outlet passage 430.

[0118] The aquaculture pond 410 is connected to the oxygen cone through the water inlet passage 420 and the water outlet passage 430.

[0119] Specifically, one end of the water inlet passage 420 is connected to the aquaculture pond 410, and the other end of the water inlet passage 420 is connected to the outlet 113 of the oxygen cone.

[0120] Specifically, one end of the water outlet passage 430 is connected to the aquaculture pond 410, and the other end of the water outlet passage 430 is connected to the inlet 112 of the oxygen cone.

[0121] A water pump 431 is connected within the water outlet passage 430. The water pump 431 is electrically connected to the control unit. A first valve 432 is connected within the water outlet passage 430.

[0122] A second valve 421 is connected inside the water inlet passage 420.

[0123] Specifically, the detection component 320 is located at the connection between the water inlet passage 420 and the aquaculture pond 410. The dissolved oxygen content at this location represents the dissolved oxygen content at the outlet 113 of the oxygen cone.

[0124] By forming a first water flow path and a second water flow path inside the oxygen cone, the first water flow path extends downward from the inlet to the bottom of the container, and the second water flow path extends upward from the bottom of the container to the outlet; the first water flow path and the second water flow path have a reverse merging part; thus, the water in the lower part of the oxygen cone flows irregularly, forming turbulence, thereby enabling full mixing of oxygen and water, allowing oxygen to dissolve better in the water, and improving the oxygenation efficiency inside the oxygen cone.

[0125] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0126] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0127] The above are merely specific embodiments 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.
