Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and more specifically, to a microporous tube aeration and oxygenation device for aquaculture. Background Technology

[0002] In aquaculture, the dissolved oxygen content in water is crucial for the survival, growth, and reproduction of aquatic organisms. Sufficient dissolved oxygen promotes metabolism, enhances immunity, and improves yield and quality. Therefore, aeration technology has become a key element in aquaculture.

[0003] Traditional aeration methods in aquaculture mainly include paddlewheel aerators and impeller aerators. Paddlewheel aerators increase dissolved oxygen by agitating the water surface, allowing air to fully contact the water. However, this method primarily works on the surface layer and has limited effect on deeper water. While impeller aerators can increase dissolved oxygen to some extent, they generate significant water flow and noise, which may cause stress to some aquaculture species that are sensitive to water flow, affecting their growth.

[0004] Existing aeration disc designs often fail to fully utilize the aeration honeycomb pores, limiting further improvements in oxygenation. Current devices cannot efficiently disperse air into sufficiently small bubbles for release into the water. Furthermore, the bubbles released by existing devices are relatively large and rise rapidly, resulting in low oxygen dissolution efficiency. Therefore, we propose an improvement: a microporous tube aeration and oxygenation device for aquaculture. Utility Model Content

[0005] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: a microporous tube aeration and oxygenation device for aquaculture, comprising a main frame of the aeration and oxygenation device, an oxygen pump installed on the front side of the main frame, the oxygen pump being connected to an oxygen inlet pipe, an inlet pipe valve being installed on the oxygen inlet pipe, the other end of the oxygen pump being connected to an air delivery pipe via a connecting elbow, the air delivery pipe being connected to an aeration booster pump, the aeration booster pump being connected to an oxygen discharge pipe, and the oxygen discharge pipe having multiple microporous aeration tubes linearly arranged thereon.

[0006] As a preferred technical solution of this utility model, the microporous aeration pipe is provided with an aeration head, and the aeration head is provided with an aeration disc.

[0007] As a preferred technical solution of this utility model, an aeration honeycomb hole is provided above the aeration disc.

[0008] As a preferred technical solution of this utility model, an electrical control box is provided on the main frame of the aeration and oxygenation device. The electrical control box is connected to the electrical box wire, and the end of the electrical box wire is provided with a wire plug.

[0009] As a preferred technical solution of this utility model, the electrical control box is connected to the oxygen pump and the aeration booster pump via electrical wires.

[0010] As a preferred technical solution of this utility model, a base is provided below the main frame of the aeration and oxygenation device, and a buffer rubber pad is provided below the base.

[0011] As a preferred embodiment of this invention, the oxygen discharge pipe is connected to the oxygen buffer tank.

[0012] As a preferred technical solution of this utility model, a pressure gauge is provided on the gas transmission pipe.

[0013] As a preferred embodiment of this invention, the oxygen inlet pipe is connected to the molecular sieve adsorption device.

[0014] As a preferred technical solution of this utility model, the molecular sieve adsorption device includes a molecular sieve adsorption tower, a molecular sieve, and a molecular sieve adsorption conveying pipe, which are connected to each other and connected to the molecular sieve adsorption tower. The molecular sieve is disposed inside the molecular sieve adsorption tower.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: The aeration disc on the microporous aeration pipe of this invention has aeration honeycomb holes, which can disperse air into countless tiny bubbles and release them into the water. These tiny bubbles rise slowly in the water, have a large contact area with the water, and remain in contact for a long time, greatly improving the oxygen dissolution efficiency. This rapidly and effectively increases the dissolved oxygen content in the aquaculture water, providing sufficient oxygen for aquatic organisms and meeting their growth and survival needs.

[0016] Reasonable gas transmission and pressurization: The oxygen pump, aeration booster pump and oxygen buffer tank work together to ensure that air can be stably extracted, pressurized and buffered, so that the gas pressure entering the water body is stable, thereby ensuring the uniformity and continuity of aeration and further improving the oxygenation effect.

[0017] This invention incorporates an electrical control box, which connects to the oxygen pump and the aeration booster pump via electrical wires. Operators can easily set parameters on the control box to precisely control the start-up, stop, operating speed, and power of the oxygen pump and the aeration booster pump. This allows the aeration process to be flexibly adjusted according to different aquaculture species, stocking densities, and aquatic environment factors, achieving precise aeration, avoiding over-aeration or under-aeration, and improving energy utilization efficiency.

[0018] The air inlet valve on the oxygen inlet pipe of this invention can adjust the air flow rate into the oxygen pump. Operators can fine-tune the air intake volume according to actual needs to better control the intensity and effect of oxygenation.

[0019] This utility model's aeration and oxygenation device has a base beneath its main frame, with a cushioning rubber pad installed underneath. This design effectively absorbs the vibrations generated during the operation of equipment such as the oxygen pump and aeration booster pump, reducing damage to the equipment and extending its service life. Simultaneously, it also reduces noise during operation, providing a relatively quiet environment for aquaculture.

[0020] The pressure gauge installed on the gas transmission pipe of this invention can display the gas pressure inside the pipe in real time. Operators can promptly detect abnormal pressure changes during gas transmission based on the pressure gauge reading, take measures to adjust in advance, avoid damage to the pipeline and related components due to excessive pressure, and ensure the stable and reliable operation of the entire oxygenation system.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1: Please refer to Figures 1-6 A microporous tube aeration and oxygenation device for aquaculture includes a main frame 1, an oxygen pump 4 is installed on the front side of the main frame 1, the oxygen pump 4 is connected to an oxygen inlet pipe 2, an inlet pipe valve 3 is installed on the oxygen inlet pipe 2, the other end of the oxygen pump 4 is connected to an air supply pipe 6 through a connecting elbow pipe 5, the air supply pipe 6 is connected to an aeration booster pump 7, the aeration booster pump 7 is connected to an oxygen exhaust pipe 8, and multiple microporous aeration tubes 9 are linearly arranged on the oxygen exhaust pipe 8.

[0032] An aeration head 10 is installed on the microporous aeration pipe 9, and an aeration disc 11 is installed on the aeration head 10. An aeration honeycomb hole 12 is opened above the aeration disc 11. An electrical control box 41 is installed on the main frame 1 of the aeration and oxygenation device. The electrical control box 41 is connected to the electrical box wire 42, and the end of the electrical box wire 42 is provided with a wire plug 43.

[0033] The electrical control box 41 is connected to the oxygen pump 4 and the aeration booster pump 7 via electrical wires. A base 13 is located below the main frame 1 of the aeration and oxygenation device, and a buffer rubber pad 14 is located below the base 13. The oxygen exhaust pipe 8 is connected to the oxygen buffer tank 16. A pressure gauge 15 is installed on the gas delivery pipe 6. The oxygen inlet pipe 2 is connected to the molecular sieve adsorption device 17.

[0034] The molecular sieve adsorption device 17 includes a molecular sieve adsorption tower 171, a molecular sieve 172, and a molecular sieve adsorption conveying pipe 173. The molecular sieve adsorption conveying pipe 173 is connected to the molecular sieve adsorption tower 171, and the molecular sieve 172 is installed inside the molecular sieve adsorption tower 171.

[0035] The working principle of the microporous tube aeration and oxygenation device for aquaculture: The aeration and oxygenation device is connected to an external power source via the plug 43 at the end of the electrical cable 42, which powers the entire device. The electrical control box 41 acts as the control center, connecting to the oxygen pump 4 and the aeration booster pump 7 via electrical cables. Operators can set relevant parameters and commands in the electrical control box 41 to precisely control the start-up, stop, operating speed, and power of the oxygen pump 4 and the aeration booster pump 7, ensuring stable operation of the device according to the set requirements.

[0036] The oxygen pump 4, acting as the power source for oxygen extraction, creates a negative pressure environment inside upon startup. Oxygen-containing ambient air, under atmospheric pressure, is drawn into the oxygen pump 4 through the oxygen inlet pipe 2 connected to it. The microporous tube aeration and oxygenation device for aquaculture is primarily used to increase dissolved oxygen in the aquaculture water to meet the respiratory needs of aquatic organisms. The method of producing slightly lower purity oxygen through molecular sieve adsorption effectively improves oxygenation efficiency. The core of molecular sieve oxygen production lies in utilizing the differences in adsorption characteristics of molecular sieves for different components in the air, adsorbing the vast majority of nitrogen gas to obtain oxygen-enriched gas.

[0037] The specific working process for producing pure oxygen by adsorption using molecular sieve 172 is as follows:

[0038] The inhaled air contains dust, moisture, and impurities, and enters the molecular sieve adsorption tower 171. The molecular sieve adsorption tower 171 contains a molecular sieve 172, which is a solid adsorbent with a uniform microporous structure, the pore size of which is comparable to the size of gas molecules. The oxygen-generating molecular sieve is a zeolite molecular sieve, which has different adsorption affinities for nitrogen and oxygen. The zeolite molecular sieve's adsorption capacity for nitrogen is much greater than its adsorption capacity for oxygen.

[0039] Air enters an adsorption tower containing molecular sieves. Nitrogen molecules in the air are preferentially adsorbed by the molecular sieves, while oxygen molecules are adsorbed relatively less. Thus, the gas passing through the adsorption tower becomes oxygen-rich, with an oxygen content of approximately 90%-95%. When air flows through the adsorption tower at a certain velocity, nitrogen molecules are captured by the micropores of the molecular sieves, while oxygen molecules can pass through smoothly, thereby achieving the separation of nitrogen and oxygen.

[0040] The oxygen-enriched gas exiting the adsorption tower enters a storage tank for storage to stabilize gas pressure and flow rate. The storage tank acts as a buffer, ensuring the stable operation of the subsequent microporous tube aeration and oxygenation device.

[0041] The oxygen pump 4 draws in oxygen-enriched air and transmits it to the air supply pipe 6 via the connecting elbow pipe 5. The pressure gauge 15 installed on the air supply pipe 6 displays the air pressure in real time, allowing operators to monitor the pressure status during gas transmission and ensure the pressure remains within the appropriate range, guaranteeing the stable operation of the entire aeration system. Insufficient air pressure in the air supply pipe 6 may affect subsequent aeration; excessive pressure may damage the pipes and related components.

[0042] The air in the air supply pipe 6 then enters the aeration booster pump 7. The aeration booster pump 7 further compresses the air, increasing its pressure to provide sufficient power for efficient aeration through the microporous aeration pipe 9. The pressurized air has a pressure sufficient to meet the requirements for uniform and stable release into the aquaculture water from the microporous aeration pipe 9.

[0043] The pressurized air enters the oxygen buffer tank 16 through the oxygen exhaust pipe 8. The oxygen buffer tank 16 serves to store and buffer oxygen, balancing the gas pressure and making the gas pressure entering the microporous aeration pipe 9 more stable. This helps ensure the uniformity and stability of aeration, avoids poor aeration effect due to gas pressure fluctuations, and ensures the uniform distribution of dissolved oxygen in the aquaculture water.

[0044] High-pressure air from the oxygen buffer tank 16 enters multiple linearly arranged microporous aeration tubes 9. Each microporous aeration tube 9 is equipped with an aeration head 10, and the aeration disc 11 mounted on the aeration head 10 is the key component for achieving microporous aeration. Numerous and tiny aeration honeycomb holes 12 are formed above the aeration disc 11. When high-pressure air passes through the aeration honeycomb holes 12, it is dispersed into countless tiny bubbles.

[0045] These tiny bubbles are released into the aquaculture water from the aeration disc 11. Due to their small size, the bubbles rise slowly in the water, resulting in a large contact area and a long contact time with the water. During the bubble's ascent, oxygen from the air can fully dissolve into the water, thereby increasing the dissolved oxygen content of the water and meeting the oxygen requirements of aquatic organisms in aquaculture, thus creating a favorable living and growth environment for them.

[0046] A base 13 is installed below the main frame 1 of the aeration and oxygenation device, and a buffer rubber pad 14 installed under the base 13 serves to absorb shock and cushion the impact. During the operation of the device, the operation of equipment such as the oxygen pump 4 and the aeration booster pump 7 will generate a certain amount of vibration. The buffer rubber pad 14 can effectively absorb and reduce these vibrations, preventing them from causing adverse effects on the device itself and the surrounding environment. It also helps to improve the stability and service life of the device, ensuring that the entire aeration and oxygenation process can be carried out continuously and stably.

[0047] Example 2: A microporous tube aeration and oxygenation device for aquaculture. The main frame 1 of the aeration and oxygenation device is made of 304 stainless steel, with overall frame dimensions of 3 meters long, 2 meters wide, and 1.5 meters high. The stainless steel pipes are assembled into a frame structure through welding, ensuring that the main frame has sufficient strength and stability to withstand the weight of each component and for long-term use in outdoor environments.

[0048] A YZ-60 vortex air pump was selected as the oxygen pump 4. This pump features a large flow rate and low noise, and can extract 60 cubic meters of air per minute to meet the oxygenation needs of the aquaculture area. The oxygen pump 4 was installed on the front side of the main frame 1 of the aeration and oxygenation device, and was firmly fixed to the preset installation position on the main frame using bolts.

[0049] The oxygen inlet pipe 2 is made of high-quality PVC pipe with an inner diameter of 60mm, and its length is determined to be 4 meters according to actual installation requirements. A manual butterfly valve is installed near the oxygen pump 4 on the oxygen inlet pipe 2 as the inlet valve 3. This butterfly valve is model D371X-10, with a nominal diameter of 60mm, and connects to the oxygen inlet pipe 2 via a flange, allowing operators to flexibly control the air intake as needed.

[0050] The connecting elbow 5 is made of stainless steel with a bending angle of 90°. The diameters at both ends match the outlet diameter of the oxygen pump 4 and the gas delivery pipe 6, both being 80mm. One end of the connecting elbow 5 is connected to the outlet of the oxygen pump 4 by welding, and the other end is connected to the gas delivery pipe 6. The gas delivery pipe 6 is a 6-meter-long rubber hose with an inner diameter of 80mm, possessing good flexibility and pressure resistance to ensure it will not rupture or deform due to gas pressure during operation.

[0051] A BZ-150 piston-type booster pump was selected as the aeration booster pump 7. This pump can boost the input gas to 0.8 MPa to ensure that the microporous aeration tube 9 can generate uniform and fine bubbles. The aeration booster pump 7 was installed on one side of the main frame and fixed with bolts. Then, the air supply pipe 6 was connected to the air inlet of the aeration booster pump 7 through a flange connection, ensuring a tight connection and no gas leakage.

[0052] The oxygen exhaust pipe 8 is a 70mm inner diameter PVC rigid pipe, 8 meters long, installed horizontally and linearly along one side of the main frame. An installation hole is made every 40cm on the oxygen exhaust pipe 8 for installing the microporous aeration pipe 9. The microporous aeration pipe 9 is made of silicone, with an inner diameter of 20mm and a length of 30cm. It is tightly connected to the installation hole on the oxygen exhaust pipe 8 using a dedicated sealing connector to ensure that gas does not leak from the connection.

[0053] A metal aeration head 10 is installed at the end of each microporous aeration tube 9. The design of the aeration head 10 enables uniform gas dispersion. A circular aeration disc 11 with a diameter of 120 mm is installed on the aeration head 10. The aeration disc 11 is made of high-strength plastic. Above the aeration disc 11, aeration honeycomb holes 12 with a diameter of 1.5 mm are evenly distributed. There are 60 aeration honeycomb holes 12 on each aeration disc 11 to achieve efficient and uniform aeration.

[0054] The electrical control box 41 is a K-200 outdoor rainproof type, equipped with an intelligent controller to automate the control of the oxygen pump 4 and the aeration booster pump 7. The electrical control box 41 is installed on the main frame near the operator for easy operation and observation. The electrical box wiring 42 uses 3×6mm² wires. 2 The cable is an 8-meter-long copper core cable. One end of the cable is connected to the power interface of the electrical control box 41, and the other end is fitted with a three-phase four-wire plug 43 with a rated current of 20A, ensuring compatibility with the power socket. The electrical control box 41 is connected to the oxygen pump 4 and the aeration booster pump 7 via two separate 2×4mm² wires. 2 This ensures stable and reliable power transmission.

[0055] At the four corners below the main frame 1 of the aeration and oxygenation device, a concrete base 13 is installed. Each base 13 measures 400mm in length, 400mm in width, and 150mm in height. Anchor bolts are pre-embedded during the pouring of the base 13 for secure connection to the main frame. A 30mm thick rubber buffer pad is adhered beneath each base 13. The rubber buffer pad is made of a material with good shock absorption properties, effectively reducing the impact of vibrations generated during device operation on the surrounding environment.

[0056] An 800L carbon steel oxygen buffer tank 16 is selected, which has good pressure resistance and corrosion resistance. The oxygen buffer tank 16 is installed near the main frame 1 of the aeration and oxygenation device and connected to the oxygen exhaust pipe 8 through a pipeline. A one-way valve is installed on the connecting pipeline to prevent gas backflow and ensure that the oxygen buffer tank 16 can stably store and output gas, thus buffering and stabilizing the gas pressure.

[0057] A Y-100T Bourdon tube pressure gauge 15 with a range of 0-1.6 MPa is installed on the gas supply pipe 6 near the aeration booster pump 7. The pressure gauge 15 is connected to the gas supply pipe 6 via a threaded connection and can display the gas pressure in the gas supply pipe 6 in real time, allowing operators to adjust the operating parameters of the device according to pressure changes.

[0058] After the device is installed, a comprehensive commissioning process is conducted. First, check that all component connections are secure, circuit connections are correct, and valves are in the correct open or closed positions. Then, connect the power supply and start the oxygen pump 4 and aeration booster pump 7, observing the device's operation. Adjust the air inlet valve 3 to control the air intake, observing the pressure gauge 15 on the air delivery pipe 6 to ensure the aeration booster pump 7 can pressurize the gas to the appropriate pressure range. Simultaneously, observe the aeration effect of the aeration heads 10 and aeration discs 11 on the microporous aeration pipe 9, checking for uniform aeration. If any abnormalities are found, immediately stop the machine for inspection and adjustment until the device operates stably, aeration is uniform, and the expected oxygenation effect is achieved. During daily operation, regularly maintain and inspect the device to ensure the normal operation of all components and extend the device's service life.

[0059] Working process of microporous tube aeration and oxygenation device for aquaculture:

[0060] Preparation stage

[0061] 1. Insert the wire plug 43 at the end of the electrical box wire 42 into a suitable power socket to connect the device to the power supply.

[0062] 2. Check the status of the air inlet valve 3 to ensure it is at the appropriate opening degree to control the amount of air entering the oxygen pump 4. At the same time, observe the pressure gauge 15 on the air supply pipe 6 to confirm that the initial pressure is normal.

[0063] Start-up phase

[0064] 1. Start the oxygen pump 4 and the aeration booster pump 7 respectively through the electrical control box 41.

[0065] 2. After the oxygen pump 4 is started, a negative pressure is formed inside it. Under the action of atmospheric pressure, outside air is drawn into the oxygen pump 4 through the oxygen inlet pipe 2. At this time, the inlet pipe valve 3 controls the amount of air entering.

[0066] 3. The oxygen pump 4 transmits the intake air to the gas supply pipe 6 through the connecting elbow pipe 5. The air flows in the gas supply pipe 6, and the pressure gauge 15 displays the pressure inside the pipe in real time.

[0067] Pressurization and buffering phase

[0068] 1. Air in the air supply pipe 6 enters the aeration booster pump 7, which compresses the air to further increase the air pressure.

[0069] 2. The pressurized air enters the oxygen buffer tank 16 through the oxygen exhaust pipe 8. The oxygen buffer tank 16 stores and buffers the air, making the gas pressure entering the microporous aeration pipe 9 more stable.

[0070] Aeration and oxygenation stage

[0071] 1. Stable high-pressure air from oxygen buffer tank 16 enters multiple linearly arranged microporous aeration tubes 9.

[0072] 2. The aeration head 10 on the microporous aeration pipe 9 has an aeration disc 11 at its top that plays a role. Air is dispersed into a large number of tiny bubbles through the aeration honeycomb holes 12 above the aeration disc 11.

[0073] 3. Microbubbles are released from the aeration disc 11 into the aquaculture water. As they rise slowly, the oxygen in the bubbles gradually dissolves into the water, thus achieving the purpose of oxygenating the aquaculture water.

[0074] Operation monitoring phase

[0075] 1. During the operation of the device, the operator can monitor the operating parameters of the oxygen pump 4 and the aeration booster pump 7 in real time through the electrical control box 41 to ensure their normal operation.

[0076] 2. Closely monitor the pressure gauge 15 on the gas supply pipe 6. If the pressure fluctuates abnormally, adjust the operating status of the device in a timely manner to avoid affecting the aeration and oxygenation effect or damaging the equipment due to pressure problems.

[0077] Stopping phase

[0078] 1. Using the electrical control box 41, first turn off the aeration booster pump 7, then turn off the oxygen pump 4.

[0079] 2. Turn off the power and unplug the plug 43 at the end of the electrical box wire 42 from the power socket.
