Description

Technical Field

[0001] This utility model is an integrated recirculating aquaculture system, belonging to the field of aquaculture. Background Technology

[0002] my country is the world's largest aquaculture nation, accounting for approximately 70% of global aquaculture production. With the continuous development of industrial aquaculture, the demand for various aquatic products is constantly increasing, leading to a proliferation of large-scale industrial aquaculture ponds. Due to the various activities of fish and the presence of humus, after a period of time, aquaculture ponds accumulate large amounts of feed, aquatic excrement, and other impurities, causing turbidity in the water. This not only affects the observation and timely intervention of aquaculture personnel but also hinders the respiration of aquatic products. Furthermore, suspended solids contain various pathogens that can adhere to the outer surface of aquatic products or enter their digestive system through ingestion, causing corresponding diseases or death, thus impacting the economic benefits of aquaculture.

[0003] In an integrated recirculating aquaculture tank for aquaculture with application number CN217645925U, the patent describes a sludge scraping device that scrapes debris from the bottom of the tank to the center, and then pumps it along with sewage through a water pump. After being filtered by a filter box, the sewage is discharged into the aquaculture tank.

[0004] The aquaculture water purification described in the above patent only uses physical filtration. However, aquaculture water contains proteins, chlorine, and organic matter. Physical filtration through a filter screen alone cannot guarantee the purification effect. Therefore, this application proposes a multi-functional integrated recirculating aquaculture device. Utility Model Content

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] An integrated recirculating aquaculture system includes an aquaculture pond, a filter element connected to the aquaculture pond via a pipe 1, a protein separator connected to one side of the filter element via a pipe 2, a dechlorination device connected to the protein separator via a pipe 3, a biochemical treatment tank connected to the dechlorination device via a pipe 3, and a return pipe 4 installed on the biochemical treatment tank.

[0008] Furthermore, the filter element includes a filter box, a collection frame is provided inside the filter box, a filter screen is provided at the bottom of the collection frame, an outer mounting plate is fixed on one side of the collection frame, the outer mounting plate is fixed to the outer side of the filter box with screws, and a sealing ring is attached to the inner side of the outer mounting plate.

[0009] Furthermore, a secondary collection frame is provided below the collection frame, and a filter screen is provided at the bottom of the secondary collection frame. Multiple mounting plates are fixed at the top of the secondary collection frame, and an insertion slot for the mounting plates is opened at the bottom of the collection frame. Corresponding threaded mounting holes are opened on the side of the collection frame and on the mounting plates.

[0010] Furthermore, differentiation nozzles are evenly arranged on the pipes that penetrate into the filter box, and an air supply device is connected to the protein separator. The air supply device includes an ozone generator, and the ozone pipe of the ozone generator is located inside the protein separator.

[0011] Furthermore, the dechlorination device includes a dechlorination tank, an agitator is installed inside the dechlorination tank, a drive motor connected to the agitator is installed at the top of the dechlorination tank, a feeding pipe with a flip-top is also installed at the top of the dechlorination tank, and the agitator blades are provided with acceleration mixing holes.

[0012] Furthermore, the biochemical treatment tank is equipped with an oxygenation pipe that extends into the tank and is connected to an external aerator. The biochemical treatment tank contains silver phosphate.

[0013] Furthermore, the inner wall of the aquaculture pond is equipped with a secondary aeration pipe, which is connected to an external secondary aerator. Aeration pipes are evenly arranged on the aeration pipe and the secondary aeration pipe. A plastic filter cylinder is screwed into the inner side of the aeration pipe, and an interception net is installed inside the plastic filter cylinder.

[0014] Furthermore, a filter cover is installed on the fourth pipe, and a filter frame is inserted into the filter cover.

[0015] The beneficial effects of this utility model are:

[0016] Fish are raised in a breeding pond as the initial water body. A filter is connected to the pond through a pipe. The filter removes large particles and excrement. The breeding pond contains feed and feces, thus achieving the filtration effect.

[0017] The filtered water is discharged into the protein separator through pipe two to remove colloids and dissolved organic matter. The purified water then enters the dechlorination unit through pipe three to remove excess chlorine, ensuring the safety of the subsequent ecological purification zone.

[0018] The biological treatment tank decomposes organic pollutants in the water into carbon dioxide and small organic molecules. Combined with the reaction between the biological treatment tank and the organic matter, the biological filtration process is highly effective, providing both physical and biological filtration to ensure a good purification effect for the circulating water.

[0019] The purified water is discharged into the aquaculture pond through pipe four for reuse. This utility model is simple to set up and has the effect of multiple purification of aquaculture water, avoiding the traditional effect of only physically filtering aquaculture water, and greatly improving the purification effect of circulating water.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0027] Please see Figure 1-4This utility model provides an integrated recirculating aquaculture system, including an aquaculture pond 1. A filter element 2 is connected to the aquaculture pond 1 via a pipe 1. A protein separator 3 is connected to one side of the filter element 2 via a pipe 2. A dechlorination device 4 is connected to the protein separator 3 via a pipe 3. A biochemical treatment pond 5 is connected to the dechlorination device 4 via a pipe 3. A pipe 27 is provided on the biochemical treatment pond 5. Pipe 27 is a return pipe.

[0028] See Figure 1-3 The filter element 2 includes a filter box 6, a collection frame 7 is provided inside the filter box 6, a filter screen 8 is provided at the bottom of the collection frame 7, an outer mounting plate 13 is fixed on one side of the collection frame 7, the outer mounting plate 13 is fixed to the outer side of the filter box 6 with screws, a sealing ring 14 is attached to the inner side of the outer mounting plate 13, a secondary collection frame 9 is provided below the collection frame 7, a filter screen 10 is provided at the bottom of the secondary collection frame 9, a plurality of mounting plates 11 are fixed at the top of the secondary collection frame 9, an insertion groove for the mounting plates 11 is opened at the bottom of the collection frame 7, and corresponding threaded mounting holes 12 are opened on the side of the collection frame 7 and on the mounting plates 11. The mounting plates 11 on the secondary collection frame 9 are inserted into the insertion groove at the bottom of the collection frame 7. By inserting screws into the threaded mounting holes 12, the secondary collection frame 9 and the collection frame 7 are fixed together. The secondary collection frame 9 and the collection frame 7 are then installed inside the filter element 2 to achieve a dual physical filtration effect. The design of the secondary collection frame 9 and the collection frame 7 effectively intercepts the filtered impurities, making subsequent cleaning of impurities more convenient. A sealing ring 14 is pasted on the inner side of the outer mounting plate 13. The sealing ring 14 is squeezed between the outer mounting plate 13 and the filter box 6 to improve the sealing performance between the two.

[0029] See Figure 1 A differentiation nozzle 15 is evenly arranged on the pipe that runs through the inside of the filter box 6. An air supply device is connected to the protein separator 3. The air supply device includes an ozone generator. The ozone pipe 16 of the ozone generator is located inside the protein separator 3. The differentiation nozzle 15 differentiates the water to improve the subsequent filtration effect. The protein separator is connected to the air supply device, which is used to provide ozone into the protein separator to purify the water that flows back into the aquaculture pond 1 after passing through the protein separator. Organic matter, microorganisms and metabolic products in the water entering the protein separator are oxidized by ozone and discharged to the outside through the drain of the protein separator. The purified water enters the dechlorination device 4, thereby purifying the water and optimizing the living environment inside the aquaculture pond 1.

[0030] See Figure 1The dechlorination device 4 includes a dechlorination tank 17, inside which is a stirrer 18. A drive motor connected to the stirrer 18 is installed at the top of the dechlorination tank 17. A feed pipe 19 with a flip-top is also installed at the top of the dechlorination tank 17. The stirring blades of the stirrer 18 have accelerated stirring holes 20. Dechlorination agent is added into the dechlorination tank through the feed pipe 19. The drive motor is started to work, stirring and mixing the water and dechlorination agent inside evenly, so that the wastewater and dechlorination agent can fully react chemically. The dechlorination agent combines with the chloride ions in the wastewater to improve the purification effect. The design of the accelerated stirring holes 20 allows water to pass through the accelerated stirring holes 20 during stirring, accelerating the water flow and improving the stirring effect. After dechlorination is completed, disinfectant can be added inside to disinfect the water.

[0031] See Figure 1 The biological treatment tank 5 is equipped with an oxygenation pipe 21 that extends into the tank and connects to an external aerator. The tank contains silver phosphate. A secondary oxygenation pipe 22 is installed on the inner wall of the aquaculture tank 1, connecting to an external secondary aerator. Aeration pipes 23 are evenly distributed along the oxygenation pipes 21 and 22. A plastic filter cartridge 24 is threaded into the inner side of each aeration pipe 23, and a screen is installed inside the filter cartridge 24. The oxygenation pipe 21 helps increase the oxygen content of the water. Silver phosphate decomposes organic pollutants in the water into carbon dioxide and small organic molecules. The combination of silver phosphate and organic matter in the biochemical filtration process results in good water treatment. The installation of the plastic filter cartridge 24 effectively prevents impurities from entering the secondary and 21 oxygenation pipes, preventing blockages and improving the overall effectiveness of the system.

[0032] See Figure 1 A filter cover 25 is installed on pipe 4 27, and a filter frame 26 is inserted into the filter cover 25. The filter frame 26 works with the filter screen inside to filter the final water, and then the water is discharged into the aquaculture pond for water supply. The filter frame is installed by pulling it out and can be installed with screws.

[0033] In operation, the aquaculture pond 1 serves as the initial water carrier for fish. A filter element 2 is connected via pipe 1, which filters out large particles and excrement. The aquaculture pond contains feed and feces, thus achieving the filtration effect. The filtered water is then discharged into a protein skimmer via pipe 2 to remove colloids and dissolved organic matter. The purified water then enters a dechlorination device via pipe 3 to remove excess chlorine, ensuring the safety of the subsequent ecological purification zone. A biochemical treatment pond 5 decomposes organic pollutants in the water into carbon dioxide and small organic molecules. Combined with the reaction between the biochemical treatment pond 5 and the organic matter, this biochemical filtration provides excellent water treatment, offering both physical and biological filtration to ensure effective purification of the circulating water. The purified water is then discharged back into the aquaculture pond 1 via pipe 4 (27) for reuse. This invention is simple to set up and provides multiple purification effects for aquaculture water, avoiding the limitations of traditional methods that only perform physical filtration, thus significantly improving the purification effect of the circulating water.

[0034] Specifically, the protein separator is a prior art technology and will not be described in detail here. Solenoid valves can be installed on pipes one through four, and pumps also need to be installed on the pipes to transport the aquaculture water. These are all conventional setups and will not be explained in detail here. Furthermore, the protein separator is a prior art technology and will not be described in detail here. Those skilled in the art can easily implement it.

[0035] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
