[0002] In the current booming development of the rice-shrimp farming industry, the dissolved oxygen level in the water plays a decisive role in the growth, reproduction and disease control of rice and shrimp. However, the traditional rice-shrimp farming oxygenation technology has revealed many problems that restrict the development of the industry in practical applications.
[0003] Traditional aeration devices lack a supporting structure for their air outlet pipes underwater, causing them to remain at the bottom of the water body for extended periods and making them highly susceptible to burial by silt. Once the air outlet pipe is partially or completely covered by silt, the air outlet will be obstructed, preventing oxygen from being released smoothly into the water. Even if the air outlet pipe is not completely buried, the silt adhering to the area around the air outlet will increase the resistance to gas discharge and reduce oxygen release efficiency. Therefore, this application designs an aeration device for rice-shrimp farming to solve the above problems. Utility Model Content

[0018] 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.
[0019] Example: See Figure 1-4This utility model discloses an oxygenation device for rice-shrimp farming, comprising a mounting base 1, with an air extraction and oxygenation device 2 mounted on top of the mounting base 1. The air extraction and oxygenation device 2 efficiently extracts and oxygenates air, continuously providing sufficient oxygen to the aquaculture water. An air conveying plate 3 is provided on one side of the air extraction and oxygenation device 2, ensuring that oxygen is evenly distributed to different areas of the aquaculture water, avoiding localized over- or under-oxygenation. Multiple connecting pipes 5 are evenly distributed on one side of the air conveying plate 3, facilitating stable and efficient oxygen delivery from the air conveying plate. The air conveying pipe 6 ensures that oxygen can smoothly enter the water body for oxygenation. One end of the connecting pipe 5 is equipped with the air conveying pipe 6, which effectively improves the dissolved oxygen level at the bottom of the aquaculture water body, improves the dissolved oxygen distribution of the entire water body, and reduces water stratification. A flange is provided between the air conveying plate 3 and the connecting pipe 5 for connection. A float plate 7 is provided on the top of the connecting pipe 5. The float plate 7 enhances the stability of the connecting pipe 5 in the water body, ensuring that oxygen can be continuously and stably delivered from the air conveying plate 3 to the air conveying pipe 6. The air conveying pipe 6 is equipped with supporting components.
[0020] In this utility model, the aeration device 2 includes an aerator located on top of the mounting base 1. The aerator contains an air impeller 9, and a ventilation plate is located on one side of the aerator. A retaining frame 10 is provided between the aerator and the ventilation plate for fixation. The retaining frame 10 ensures the stability and sealing of the connection between the ventilation plate and the aerator, allowing the ventilation plate to accurately and reliably adjust the air intake of the aerator, thereby ensuring the normal operation and efficient aeration of the aerator. A filter frame 8 is installed on the inner wall of the aerator's outlet end, and a main pipe is threadedly connected to the outlet end. One end of the main pipe is connected to the air conveying plate 3. The filter frame 8 ensures the purity of the oxygen entering the aquaculture water, reducing the risk of water quality deterioration caused by impurities entering the water. The supporting components include multiple air outlet pipes 1 equidistantly located at the bottom of the air conveying submersible pipe 6. 2. Mud-proof support frames 13 are snapped at both ends of the air outlet pipe 12. Filter plates are screwed onto the air outlet ends of the air outlet pipe 12. The support components enhance the stability of the air outlet pipe 12 at the bottom of the water body, ensuring unobstructed airflow at the air outlet ends of the air outlet pipe 12, improving the reliability and stability of oxygen release, and effectively preventing a decrease in oxygenation effect due to problems with the air outlet pipe 12. The bottom of the float plate 7 has three arc-shaped grooves, and cable ties 11 are installed in the three arc-shaped grooves. The float plate 7 is bound to the top of the connecting pipe 5 by the cable ties 11. The cable ties 11 facilitate a stable connection between the float plate 7 and the connecting pipe 5, ensuring that the float plate 7 can effectively exert its buoyancy. One end of the connecting pipe 5 is equipped with a butterfly valve 4 for controlling the flow rate. The butterfly valve 4 facilitates precise control of the oxygen delivery volume, improving the targeting and effectiveness of oxygenation.
[0021] Working Principle: When using this invention, the exhaust aeration device 2 is first activated. The air supply impeller 9 inside the aerator rotates at high speed driven by a motor. The rapid rotation of the impeller creates a negative pressure inside the aerator. Outside air is drawn in by this negative pressure and enters the aerator through the ventilation plate. The ventilation plate can adjust the air intake to meet the aeration needs under different working conditions. The air entering the aerator is thoroughly mixed with the existing gas inside the aerator under the stirring and compression action of the air supply impeller 9, increasing the proportion of oxygen in the mixed gas and completing the initial aeration treatment. Then, the oxygen-rich air... The airflow is output from the aerator outlet. The filter frame 8 installed on the inner wall of the aerator outlet functions to intercept dust, impurities, and other particulate matter in the airflow, ensuring the purity of the output gas. Subsequently, the airflow enters the main pipe, which guides it to the air distribution plate 3. The air distribution plate 3 acts as a distribution hub, evenly distributing the airflow to each connecting pipe 5, ensuring that each connecting pipe 5 receives a stable and appropriate amount of oxygen. Then, a butterfly valve 4 is installed at one end of each connecting pipe 5, allowing aquaculture personnel to flexibly adjust the valve according to actual aquaculture needs, such as stocking density, water temperature, and the rice-shrimp growth stage. The valve plate of the rotary butterfly valve 4 regulates the flow rate of oxygen in the connecting pipe 5, precisely controlling the oxygen flow rate entering the gas delivery submersible 6. The connecting pipe 5 has a Z-shaped design. When the gas flows in the pipe, the Z-shaped structure increases the contact time and area between the gas and the pipe wall, allowing the gas to be further mixed evenly. At the same time, it buffers the airflow pressure to a certain extent, reducing the impact on the gas delivery submersible 6. Finally, the connecting pipe 5 delivers the oxygen flow to the gas delivery submersible 6, which sinks to the bottom of the aquaculture water. At the bottom, the gas delivery submersible 6 releases oxygen evenly to the bottom of the water through the equally spaced air outlet pipes 12. The anti-mud support frame 13, which is snapped at both ends of the air pipe 12, provides stable support for the air pipe 12 to prevent it from sinking, tilting or blocking due to water flow and silt accumulation. On the other hand, the special structural design can prevent silt and other impurities from clogging the air outlet of the air pipe 12, ensuring smooth release of oxygen. The oxygen released from the air pipe 12 quickly dissolves in the bottom water, directly increasing the dissolved oxygen content of the bottom water. As the dissolved oxygen in the bottom increases, it promotes the exchange of dissolved oxygen between the upper and lower layers of the water, improves the dissolved oxygen distribution of the entire water body, and reduces water stratification. At this point, the use of the oxygenation device for rice-shrimp farming is completed.
