Description

Technical Field

[0001] This utility model relates to the field of oxygen generators for aquaculture, specifically an oxygen generator for factory-scale recirculating aquaculture. Background Technology

[0002] Oxygen generators used in factory-scale recirculating aquaculture systems mostly employ pressure swing adsorption (PSA) technology. This technology offers efficient, stable, and controllable oxygen supply, significantly improving dissolved oxygen levels in the water to meet the demands of high-density aquaculture. It is one of the core components of factory-scale recirculating aquaculture systems. By utilizing the difference in adsorption capacity between nitrogen and oxygen by zeolite molecular sieves, gas separation is achieved. Under pressure, the molecular sieve adsorbs nitrogen, while oxygen is enriched and discharged. Under pressure reduction, nitrogen desorbs, and the molecular sieve regenerates. This technology produces oxygen with high purity (up to 93% ± 3%) and provides continuous and stable oxygen supply, making it suitable for high-density aquaculture scenarios.

[0003] However, in most traditional aquaculture, the oxygen supply pipe structure of oxygen generators is simple (such as a single straight pipe or ordinary microporous pipe), which leads to uneven oxygen distribution, resulting in problems such as excessively high dissolved oxygen (wasting energy) or excessively low dissolved oxygen (fish and shrimp die from lack of oxygen). Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the simple structure of oxygen supply pipes in most traditional aquaculture aquaculture systems leads to uneven oxygen distribution, resulting in problems such as excessively high or low dissolved oxygen levels in certain areas. This invention proposes an oxygen generator for factory-scale recirculating aquaculture.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an oxygen generator for factory-type circulating water aquaculture, including an oxygen generator body, a movable wheel fixedly connected to the bottom of the oxygen generator body, an oxygen supply pipe fixedly connected to one side of the oxygen generator body, and an oxygen treatment component provided at one end of the oxygen supply pipe.

[0006] The oxygen treatment assembly includes a narrow neck tube, one end of which is fixedly connected to one end of an oxygen supply tube, and the other end of which is fixedly connected to a shunt tube. The inner cavity of the shunt tube is provided with a shunt plate, and there are multiple shunt plates.

[0007] Preferably, the diverter includes a first arc-shaped plate, a sealing layer is provided on one side of the first arc-shaped plate, and a second arc-shaped plate is provided on the other side of the sealing layer, with the first arc-shaped plate and the second arc-shaped plate fixedly connected.

[0008] Preferably, the diverter plate includes a connecting plate, and a flow guide shroud is fixedly connected to one side of the connecting plate, and a through hole is provided on one side of the flow guide shroud.

[0009] Preferably, the inner walls of both the first and second arc-shaped plates are fixedly connected to a fixing plate, and the surface of the connecting plate is snapped into the inner wall of the fixing plate.

[0010] Preferably, the inner wall of the fixing plate is provided with a buffer pad, and one side of the connecting plate is attached to one side of the buffer pad.

[0011] Preferably, the other end of the diversion pipe is fixedly connected to a laying pipe, the other end of the laying pipe is fixedly connected to an aeration disc, and a filter screen is fixedly connected to one side of the aeration disc.

[0012] The advantages of this utility model are:

[0013] This invention utilizes a narrow neck tube in the oxygen treatment component to accelerate the gas as it passes through, allowing it to quickly enter the distribution pipe and be distributed by the distribution plate. This enables the oxygen to be released evenly at the bottom of the aquaculture pond, improving the uniformity of oxygen supply, extending the oxygen residence time, and facilitating oxygen dissolution. It solves the problem in most traditional aquaculture where the simple structure of the oxygen supply pipe of the oxygen generator leads to uneven oxygen distribution, resulting in localized excessively high or low dissolved oxygen levels.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses an oxygen generator for factory-scale circulating water aquaculture. (Refer to...) Figures 1 to 4 An oxygen generator for factory-scale recirculating aquaculture includes an oxygen generator body 1, with casters 2 fixedly connected to the bottom of the oxygen generator body 1, an oxygen supply pipe 3 fixedly connected to one side of the oxygen generator body 1, and an oxygen treatment component 4 provided at one end of the oxygen supply pipe 3.

[0024] The oxygen treatment component 4 includes a narrow neck tube 401, one end of which is fixedly connected to one end of the oxygen supply tube 3, and the other end of which is fixedly connected to a diversion tube 402. The inner cavity of the diversion tube 402 is provided with a diversion plate 403, and there are multiple diversion plates 403. This is an oxygen generator for aquaculture in a chemical circulating water system. The oxygen generator body 1 can be moved by the moving wheels 2. The oxygen generator body 1 can form oxygen with a high content through processes such as air compressor compression and molecular sieve adsorption of nitrogen. Oxygen can be supplied to the aquaculture pond through the oxygen supply tube 3, which is connected to the oxygen treatment component 4. The narrow neck tube 401 in the oxygen treatment component 4 can accelerate the gas as it passes through, allowing the gas to quickly enter the diversion tube 402 and be diverted by the diversion plate 403. This can make the oxygen released evenly at the bottom of the aquaculture pond, improve the uniformity of oxygen supply, prolong the oxygen residence time, and facilitate oxygen dissolution.

[0025] Reference Figure 3 and Figure 4, the shunt pipe 402 includes a first arc-shaped plate 4021. A sealing layer 4022 is provided on one side of the first arc-shaped plate 4021. A second arc-shaped plate 4023 is provided on the other side of the sealing layer 4022. The first arc-shaped plate 4021 and the second arc-shaped plate 4023 are fixedly connected. By providing the shunt pipe 402, the shunt pipe 402 is mainly composed of the combination of the first arc-shaped plate 4021 and the second arc-shaped plate 4023, which improves the convenience of disassembly and assembly. The sealing layer 4022 can be sealed with materials such as rubber.

[0026] Refer to Figure 4 , the shunt plate 403 includes a connecting plate 4031. A flow guide cover 4032 is fixedly connected to one side of the connecting plate 4031. A through hole 4033 is provided on one side of the flow guide cover 4032. By providing the shunt plate 403, the connecting plate 4031 in the shunt plate 403 mainly plays a connecting role. The flow guide cover 4032 can improve the concentration of oxygen. The shunt plate 403 is provided with three to five micro-hole plates with gradually decreasing through hole 4033 apertures, so that the oxygen flow is gradually dispersed to avoid single-stage high-pressure impact.

[0027] Refer to Figure 4 , fixing plates 404 are fixedly connected to the inner walls of both the first arc-shaped plate 4021 and the second arc-shaped plate 4023. The surface of the connecting plate 4031 is clamped to the inner wall of the fixing plate 404. By providing the fixing plate 404, the shunt plate 403 is mainly installed in the inner cavity of the shunt pipe 402 through the cooperation of the connecting plate 4031 and the fixing plate 404, and the convenience of disassembly and assembly of the shunt plate 403 can be improved by means of clamping.

[0028] Refer to Figure 4 , a buffer pad 5 is provided on the inner wall of the fixing plate 404. One side of the connecting plate 4031 is in contact with one side of the buffer pad 5. By providing the buffer pad 5, the buffer pad 5 can be made of rubber material, which can slow down the vibration generated by the rapid flow of oxygen and shunting as much as possible, and extend the service life of the shunt plate 403.

[0029] Refer to Figure 2 and Figure 5 , the other end of the shunt pipe 402 is fixedly connected to a laying pipe 6. The other end of the laying pipe 6 is fixedly connected to an aeration disc 7. A filter screen 8 is fixedly connected to one side of the aeration disc 7. By providing the aeration disc 7, multiple laying pipes 6 can be used to form a laying at the bottom of the aquaculture pond. The laying pipe 6 is preferably laid in a "rich" shape to reduce the turning points and ensure the oxygen delivery. Multiple aeration discs 7 are provided on the laying pipe 6. Multiple aeration discs 7 can also be used. The aeration disc 7 can release oxygen in the form of tiny bubbles, with the surface area increased by 30 - 50 times, significantly improving the oxygen dissolution efficiency. The filter screen 8 can avoid the impurities in the aquaculture pond from blocking the air holes on the aeration disc 7 while ensuring the oxygen supply of the aeration disc 7.

[0030] Working principle: The oxygen generator body 1 can be moved through the moving wheels 2. The oxygen generator body 1 can form oxygen with a relatively high content through processes such as the compression of the air compressor and the adsorption of nitrogen by the molecular sieve. Oxygen can be supplied to the aquaculture pond through the oxygen supply pipe 3. The oxygen supply pipe 3 is connected to the oxygen treatment component 4. The narrow neck pipe 401 in the oxygen treatment component 4 can accelerate the gas when it passes through, enabling the gas to quickly enter the shunt pipe 402 and be shunted through the shunt plate 403. The connecting plate 4031 in the shunt plate 403 mainly plays a connecting role. The flow guide cover 4032 can improve the concentration of oxygen. The shunt plate 403 is provided with three to five microporous plates with gradually decreasing pore diameters of the through holes 4033, so that the oxygen flow is gradually dispersed to avoid single-stage high-pressure impact. The laying pipes 6 can be composed of multiple pipes and are laid at the bottom of the aquaculture pond. The laying pipes 6 are preferably laid in a "rich" shape to reduce the turning points and ensure the delivery of oxygen. A plurality of aeration discs 7 are provided on the laying pipes 6. The aeration discs 7 can also be multiple. The aeration discs 7 can release oxygen in the form of tiny bubbles, with the surface area increased by 30 - 50 times, significantly improving the oxygen dissolution efficiency. The filter screen 8 can avoid the impurities in the aquaculture pond from blocking the air holes on the aeration discs 7 while ensuring the oxygen supply of the aeration discs 7, enabling the oxygen to be evenly released at the bottom of the aquaculture pond, improving the uniformity of oxygen supply, prolonging the oxygen residence time, and being beneficial to oxygen dissolution.
