Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and more specifically, to a self-cleaning recirculating aquaculture system. Background Art

[0002] In aquaculture, regularly cleaning fishponds of feces, uneaten feed, and other impurities is crucial for maintaining clean water quality, which is fundamental to ensuring the healthy growth of aquatic organisms. Furthermore, improving water quality can effectively reduce the incidence of disease and improve the quality of aquatic products. Currently, in indoor ornamental fish farming, filtration systems are typically used to remove pollutants from the water, and the treated water is recycled.

[0003] When polluted water flows through filter media, although most solid waste is trapped, the soluble substances released can still re-enter the aquarium, causing secondary pollution. Especially under high-density rearing conditions, the large amount of feed leads to the accumulation of uneaten food and excrement, causing a sharp rise in ammonia and nitrite levels in the water. This not only seriously affects water quality but also significantly increases the risk of fish disease, particularly in the later stages of the rearing cycle. Utility Model Content

A first connecting gear 10 is fixedly connected to the filter barrel 9. A servo motor 11 is installed inside the hydroxyl radical zone 3. A second connecting gear 12 is fixedly connected to the output shaft of the servo motor 11, and the second connecting gear 12 meshes with the first connecting gear 10. Protective plates 26 are hinged to the tops of the hydroxyl radical zone 3, the anaerobic zone 4, and the aerobic zone 5 to prevent external impurities from entering the treatment frame 2.

[0021] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes a partition 8, a drain pipe 13, a collection frame 14, a second water pump 15, a third water pipe 16, and a nozzle 17. The partition 8 is fixedly connected to the front of the hydroxyl radical region 3. The drain pipe 13 is fixedly connected inside the hydroxyl radical region 3. The drain pipe 13 is located inside the filter bucket 9. The collection frame 14 is rotatably connected inside the filter bucket 9. The collection frame 14 is connected to the drain pipe 13.

The nozzle 17 is fixedly connected inside the hydroxyl radical region 3. The third water pipe 16 is connected to the nozzle 17.

[0022] like Figure 2 and Figure 6 As shown, it also includes an oil-free compressor 19, a connecting pipe 20, and an aeration disc 21. An oil-free compressor 19 with a built-in oxygen-nitrogen separation molecular sieve is fixedly connected to the rear side of the treatment frame 2. The two exhaust ends of the oil-free compressor 19 are respectively fixedly connected to the connecting pipe 20. One connecting pipe 20 extends into the anaerobic zone 4, and the other connecting pipe 20 extends into the aerobic zone 5. An aeration disc 21 is fixedly connected to the side of the connecting pipe 20 away from the oil-free compressor 19.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the water supply assembly includes a third water pump 22, a fourth water pipe 23, a fifth water pipe 24, and a branch pipe 25. The third water pump 22 is fixedly connected to the front side of the treatment frame 2. The fourth water pipe 23 is fixedly connected to the pumping end of the third water pump 22. The fourth water pipe 23 is connected to the aerobic zone 5. The fifth water pipe 24 is fixedly connected to the drain end of the third water pump 22.

The three branch pipes 25 are evenly distributed around the fish tank 1, and the drain ends of the three branch pipes 25 are connected to the fish tank 1.

[0024] Wastewater from the fish tank 1 is pumped out of the first water pipe 61 by the first water pump 6 and then discharged into the filter tank 9 through the second water pipe 7 for filtration. The second connecting gear 12 is driven to rotate by the servo motor 11. Under the meshing action of the first connecting gear 10 and the second connecting gear 12, the second connecting gear 12 drives the first connecting gear 10 to rotate, causing the filter tank 9 to rotate. The suspended solids in the wastewater are filtered through the 200-mesh filter screen on the filter tank 9. The wastewater passes through the filter tank 9 and flows into the hydroxyl radical zone 3. The oil-free compressor 19, in conjunction with the oxygen-nitrogen separation molecular sieve, can separate oxygen and nitrogen from the air. The nitrogen is then discharged into the aeration disc 21 in the anaerobic zone 4 through one connecting pipe 20 and through the other connecting pipe 20. Pure oxygen is discharged into the aeration disc 21 within the aerobic zone 5, creating highly oxygenated dissolved water. When it's necessary to clean suspended matter from the filter screen, the highly oxygenated dissolved water is extracted from the aerobic zone 5 via a hydroxyl radical water generator. This generator then converts the highly oxygenated dissolved water into highly oxygenated hydroxyl radical water, which is sprayed onto the filter screen through nozzle 17. This process quickly removes residual feed, feces, and suspended matter from the aquaculture water, reducing the conversion of suspended matter into ammonia nitrogen and lowering the production of harmful pollutants such as ammonia nitrogen and nitrite nitrogen. This purifies the aquaculture water environment, providing a stable, reliable, comfortable, and high-quality growth environment for aquaculture organisms and creating favorable conditions for high-density aquaculture. Nozzle 17 can also... The filter screen is rinsed to remove suspended solids adhering to it into the collection frame 14. These suspended solids are then discharged from the collection frame 14 through the drain pipe 13 to prevent clogging and ensure proper filter operation. Wastewater is discharged from the hydroxyl radical zone 3 into the anaerobic zone 4 via the conduit 18, and then from the anaerobic zone 4 into the aerobic zone 5. Nitrifying bacteria in the aerobic zone 5 convert ammonia nitrogen in the wastewater into nitrates and nitrites, thus completing the nitrification reaction. The wastewater containing nitrates and nitrites forms the nitrified liquid. The nitrified liquid flows back into the hydroxyl radical zone 3 through the conduit 18 between the hydroxyl radical zone 3 and the aerobic zone 5, and then flows into the anaerobic zone through the conduit 18 between the hydroxyl radical zone 3 and the anaerobic zone 4. Within zone 4, the denitrification reaction is completed. The high-oxygen hydroxyl radical water in zone 3 can react rapidly with most organic pollutants, decomposing them into smaller molecules, or even completely mineralizing them into carbon dioxide and water. This improves the biodegradability of suspended solids, making them easier for denitrifying bacteria to utilize in the subsequent anaerobic zone 4, thus improving nitrogen removal efficiency. After being filtered and cleaned by the filter tank 9, hydroxyl radical zone 3, anaerobic zone 4, and aerobic zone 5, the wastewater is transformed into high-oxygen purified water. Then, the high-oxygen purified water in aerobic zone 5 is pumped out from the fourth water pipe 23 by the third water pump 22 and discharged into the distribution pipe 25 from the fifth water pipe 24. The high-oxygen purified water is then injected into the fish tank 1 through the distribution pipe 25, thus achieving a self-cleaning water cycle.
