Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to an oxygen-water mixing device for recirculating aquaculture. Background Technology

[0002] "Oxygen-water mixing" generally refers to the process of mixing oxygen with water to increase the oxygen content in the water. This process is important for many applications, such as fish farming, aquarium management, wastewater treatment, and certain industrial processes. The principle of oxygen-water mixing is based on Henry's Law, which states that at a given temperature, the solubility of a gas in water is directly proportional to its partial pressure. Therefore, by increasing the partial pressure of oxygen in the water, the dissolved oxygen content can be increased. This is typically achieved through aeration or the use of an oxygen pump.

[0003] In order to ensure that oxygen and water are fully mixed, mechanical stirring is required in some oxygen-water mixing systems, which not only has high operating costs but also generates a lot of noise during operation. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an oxygen-water mixing device for recirculating aquaculture, which solves the problem of high operating costs associated with mechanical stirring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxygen-water mixing device for recirculating aquaculture, comprising a water tank one, an inlet pipe fixedly connected to the surface of the water tank one, a limiting plate fixedly connected inside the water tank one, filter cotton inserted inside the limiting plate, a guide pipe fixedly connected to the surface of the water tank one, a water tank two fixedly connected to the other end of the guide pipe, a vertical pipe fixedly connected to the upper surface of the water tank two, a baffle plate fixedly connected inside the vertical pipe, an air-inflating pipe fixedly connected to the surface of the vertical pipe, a one-way valve fixedly connected to the other end of the air-inflating pipe, an air guide pipe movably installed on the surface of the one-way valve, a diverter pipe fixedly connected to the other end of the air guide pipe, an air inlet pipe fixedly connected to the bottom end of the diverter pipe, an oxygen pump fixedly connected to the bottom end of the air inlet pipe, a regulating valve fixedly installed on the surface of the air inlet pipe, and a water tank three fixedly connected to the top end of the vertical pipe.

[0006] Preferably, a water outlet pipe is fixedly connected to the surface of the water tank three, and a flange is fixedly connected to one end of both the water outlet pipe and the water inlet pipe.

[0007] Preferably, a cover is threaded onto the surface of the water tank.

[0008] Preferably, the inflation tubes are arranged in a staggered pattern, and the position of the folding plate corresponds to that of the inflation tubes.

[0009] Preferably, the inside of the diversion tube is hollow.

[0010] Preferably, the inflation tube is tilted, with the suspended end being higher.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This recirculating aquaculture oxygen-water mixing device, with its inlet pipe, allows for easy pipe connection, enabling water to be injected into water tank one. The filter cotton effectively filters the water entering water tank one, improving its purity. The filtered water then flows into water tank two through a guide pipe. Water tank two, in conjunction with a vertical pipe, allows water to flow upwards. Due to the inclined design of the air inlet pipe, some water enters the air inlet pipe. The oxygen pump generates oxygen, which is then distributed through the air inlet pipe into the distribution pipe, allowing it to flow from each section of the air inlet pipe into the respective air inlet pipe. A one-way valve prevents water from entering the air inlet pipe. The oxygen not only mixes with the water but also pushes the water back, causing some water to flow back and mix with the water in the vertical pipe, thus ensuring efficient oxygen-water mixing and saving costs.

[0013] 2. The oxygen-water mixing device for recirculating aquaculture uses a baffle plate to facilitate the diversion of water flow in the vertical pipe, making it easier for water to enter the aeration pipe and mix with the oxygen-water in the aeration pipe. The oxygen-water flowing back from the aeration pipe to the vertical pipe can be pushed into the water tank. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides the following technical solution: an oxygen-water mixing device for recirculating aquaculture, comprising a water tank 1, an inlet pipe 2 fixedly connected to the surface of the water tank 1, a limiting plate 3 fixedly connected inside the water tank 1, a filter cotton 4 inserted inside the limiting plate 3, a guide pipe 5 fixedly connected to the surface of the water tank 1, a water tank 2 6 fixedly connected to the other end of the guide pipe 5, a vertical pipe 7 fixedly connected to the upper surface of the water tank 2 6, a folding plate 8 fixedly connected inside the vertical pipe 7, an air inlet pipe 9 fixedly connected to the surface of the vertical pipe 7, a one-way valve 18 fixedly connected to the other end of the air inlet pipe 9, an air guide pipe 10 movably installed on the surface of the one-way valve 18, a diversion pipe 11 fixedly connected to the other end of the air guide pipe 10, an air inlet pipe 12 fixedly connected to the bottom end of the diversion pipe 11, an oxygen pump 13 fixedly connected to the bottom end of the air inlet pipe 12, a regulating valve 14 fixedly installed on the surface of the air inlet pipe 12, and a water tank 3 15 fixedly connected to the top end of the vertical pipe 7.

[0023] In this embodiment, the inlet pipe 2 facilitates pipe connection, allowing water to be injected into water tank 1. The filter cotton 4 helps filter the water entering water tank 1, improving its purity. The filtered water can then enter water tank 6 through the guide pipe 5. Water tank 6, in conjunction with the vertical pipe 7, allows water to flow from bottom to top. Due to the inclined design of the air inlet pipe 9, some water can enter it. The oxygen pump 13, through its operation, generates oxygen which enters the diversion pipe 11 through the air inlet pipe 12. The flow is divided so that each section of the air guide pipe 10 can enter the respective air filling pipe 9. The one-way valve 18 helps to prevent water from entering the air guide pipe 10. Oxygen not only mixes with water, but can also push water in the opposite direction, so that some water flows back and mixes with the water in the vertical pipe 7. This ensures the efficiency of oxygen-water mixing and saves costs. The setting of the baffle plate 8 can facilitate the diversion of water flow in the vertical pipe 7, making it easier for water to enter the air filling pipe 9, and also facilitates collision and mixing with the oxygen-water in the air filling pipe 9. The oxygen-water that flows back from the air filling pipe 9 to the vertical pipe 7 can be pushed into the water tank 15.

[0024] Specifically, a water outlet pipe 16 is fixedly connected to the surface of water tank 3 15. Oxygenated water in water tank 3 15 can be discharged and used through the water outlet pipe 16. A flange is fixedly connected to one end of the water outlet pipe 16 and the water inlet pipe 2. The flange facilitates the tight connection between the external water guide pipe and the water outlet pipe 16 and the water inlet pipe 2, thereby facilitating water inlet and outlet.

[0025] Specifically, a cover 17 is threaded onto the surface of water tank 1. The cover 17 can be separated from water tank 1, making it easy to remove the filter cotton 4 for cleaning or replacement.

[0026] Specifically, the air tubes 9 are staggered, which allows water in the vertical tube 7 to enter the air tubes 9 separately, avoiding the situation where some water cannot be oxygenated due to the inability to divert the flow. The position of the baffle 8 corresponds to the air tubes 9. Through the setting of the baffle 8, it plays a guiding role, which allows water in the vertical tube 7 to enter different air tubes 9 multiple times.

[0027] Specifically, the interior of the split pipe 11 is hollow, so that the oxygen entering through the air inlet pipe 12 fills the split pipe 11, and the oxygen is split through the air guide pipe 10.

[0028] Specifically, the air inlet pipe 9 is tilted and the suspended end is higher, so that water flowing from bottom to top can easily enter the air inlet pipe 9, and the oxygenated water in the air inlet pipe 9 can easily flow back to the vertical pipe 7.

[0029] The working principle or usage process of this utility model is as follows: First, connect the pipe to the inlet pipe 2 and the outlet pipe 16 respectively. Water can be injected into the water tank 1 through the inlet pipe 2. The filter cotton 4 filters the water entering the water tank 1, thereby improving the purity of the water. The filtered water can enter the water tank 6 through the guide pipe 5. Through the water tank 6 and the vertical pipe 7, the water can flow from bottom to top. Due to the inclined setting of the air filling pipe 9, some water can enter the air filling pipe 9. Then, the oxygen pump 13 is started. The oxygen generated by its operation enters the diversion pipe 11 through the air inlet pipe 12 for diversion, so that it can enter the respective air filling pipes 9 from each section of the air guide pipe 10. The one-way valve 18 helps to prevent water from entering. The oxygen in the air inlet pipe 10 not only mixes with water but also pushes water in the reverse direction, allowing some water to flow back and mix with the water in the vertical pipe 7. This ensures efficient oxygen-water mixing and saves costs. The oxygen pump 13 adjusts the oxygen intake, and the baffle plate 8 facilitates the redirection of water flow in the vertical pipe 7, making it easier for water to enter the air filling pipe 9 and to collide and mix with the oxygen-water mixture in the air filling pipe 9. The oxygen-water flowing back from the air filling pipe 9 to the vertical pipe 7 can be pushed into the water tank 15. The surface of the water tank 15 is fixedly connected to the outlet pipe 16, and the oxygen-water mixture in the water tank 15 can be discharged and utilized through the outlet pipe 16 and other pipes. All electrical equipment in this device is externally powered and its operation and shutdown are controlled by a matching control switch.

[0030] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the utility model. The selection and detailed description of these embodiments in this specification are for the purpose of better explaining the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
