Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically to a water-circulating high-density aquaculture system for fish and shrimp fry. Background Technology
[0002] With the rapid development of aquaculture technology, integrated aquaculture facilities have emerged to meet the demand for fresh fish, shrimp, and other aquatic products under varying farming conditions, and to facilitate large-scale farming and increase yields. These facilities consist of multiple interconnected, independent aquaculture units operating as a single module. This structure allows for individual temperature and pH adjustments, as well as wastewater treatment, in different aquaculture units. However, existing integrated aquaculture facilities have the following shortcomings: First, the water circulation control in these interconnected ponds involves large flow rates and significant energy loss, resulting in poor sensitivity. Second, the ponds are typically exposed to the elements, making them susceptible to water quality issues caused by wind and rain. Third, the layout is often inefficient, requiring a large land area. Utility Model Content
[0003] The purpose of this invention is to provide a parallel independent water circulation treatment system for high-density aquaculture of fish and shrimp fry with low water circulation flow, low energy loss, and high control sensitivity.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] A parallel independent water recirculation treatment type high-density aquaculture system for fish and shrimp fry includes a typhoon-resistant sunroom, an aquaculture water treatment tower, and multiple independent recirculating aquaculture ponds. The multiple independent recirculating aquaculture ponds and the aquaculture water treatment tower are located inside the typhoon-resistant sunroom. The aquaculture water treatment tower is mounted on a support frame, and the multiple independent recirculating aquaculture ponds are distributed around the perimeter of the aquaculture water treatment tower. The bottom of the aquaculture water treatment tower is a conical sludge collection tank, and a sludge discharge pipe is installed at the bottom of the conical sludge collection tank. Multiple water inlets are distributed circumferentially on the lower part of the aquaculture water treatment tower, and these inlets are located above the conical sludge collection tank. Multiple water inlets are distributed circumferentially on the upper part of the aquaculture water treatment tower. The aquaculture water treatment tower has multiple outlets located between the inlet and outlet. From bottom to top, it is equipped with an aquaculture water filtration module and a biofilm treatment module. The drain outlets at the center of multiple independent circulating aquaculture ponds are connected to multiple inlets on the aquaculture water treatment tower through aquaculture water discharge pipes. A water pump is installed on the aquaculture water discharge pipes.

A probiotic dosing device is installed at the top of the aquaculture water treatment tower to add probiotics into the aquaculture water treatment tower.
[0006] Furthermore, the probiotic dispensing device includes a probiotic storage box, a probiotic discharge control cylinder, a dispensing pipe, a probiotic discharge control screw, and a servo motor. The probiotic discharge control cylinder is placed horizontally, with one end connected to the bottom side of the probiotic storage box. One end of the probiotic discharge control screw extends into the probiotic discharge control cylinder, and the other end of the probiotic discharge control screw is connected to the output shaft of the servo motor. The bottom of the cylinder wall of the probiotic discharge control cylinder is provided with a probiotic discharge outlet. The upper end of the dispensing pipe is connected to the probiotic discharge outlet, and the lower end of the dispensing pipe extends from the top of the aquaculture water treatment tower into the aquaculture water treatment tower.
[0007] Furthermore, it also includes a control system, which includes a controller, an ammonia nitrogen sensor for aquaculture water, and a pH sensor for aquaculture water. The ammonia nitrogen sensor and the pH sensor for aquaculture water are installed in each of the independent circulating aquaculture ponds. The ammonia nitrogen sensor and the pH sensor for aquaculture water transmit information to the controller, which regulates the water pump and the servo motor in the probiotic dosing device.
[0008] Furthermore, the control system also includes an aquaculture water temperature sensor. Each of the independent circulating aquaculture tanks is equipped with the aquaculture water temperature sensor, and each aquaculture water return pipe is equipped with an electric heater.

[0009] Furthermore, the control system also includes a dissolved oxygen sensor for aquaculture water. Each independent recirculating aquaculture tank is equipped with a blower, an aeration pipe, and the dissolved oxygen sensor. The blower supplies air to the aeration pipe, which is used to increase the oxygen in the aquaculture water in the independent recirculating aquaculture tank. The dissolved oxygen sensor transmits the dissolved oxygen level of the aquaculture water in the independent recirculating aquaculture tank to the controller, which regulates the blower.
[0010] Furthermore, the bottom surface of the independent recirculating aquaculture tank is provided with multiple annular aeration pipes, which are arranged in concentric circles.
[0011] Furthermore, the aeration pipe is provided with multiple aeration heads, which face the bottom of the independent recirculating aquaculture tank and are inclined toward the center of the independent recirculating aquaculture tank.

[0025] like Figure 1 , 2 As shown in Figure 3, a parallel independent water circulation treatment type high-density aquaculture system for fish and shrimp fry includes a typhoon-resistant sunroom 1, an aquaculture water treatment tower 2, and multiple independent recirculating aquaculture ponds 3. The multiple independent recirculating aquaculture ponds 3 and the aquaculture water treatment tower 2 are located inside the typhoon-resistant sunroom 1. The aquaculture water treatment tower 2 is mounted on a support frame 4. The multiple independent recirculating aquaculture ponds 3 are distributed around the aquaculture water treatment tower 2. The bottom of the aquaculture water treatment tower 2 is a conical sludge collection tank 5, and the bottom of the conical sludge collection tank 5 is equipped with a drain pipe 6. Multiple water inlets 7 are distributed circumferentially along the lower part of the tower body of the aquaculture water treatment tower 2, and the water inlets 7 are located above the conical sludge collection tank 5. The aquaculture water treatment tower 2 has multiple outlets 8 distributed circumferentially on the upper part of the tower body. Inside the aquaculture water treatment tower 2, between the inlet 7 and the outlets 8, there are aquaculture water physical filtration module 9 and a biofilm treatment module 10 respectively from bottom to top. The drain outlets 11 at the center of multiple independent circulating aquaculture ponds 3 are connected to multiple inlet outlets 7 on the aquaculture water treatment tower through aquaculture water discharge pipes 12. A water pump 13 is installed on the aquaculture water discharge pipes 12. The multiple outlets 8 on the aquaculture water treatment tower 2 are connected to one end of multiple aquaculture water return pipes 14 respectively. The other end of the multiple aquaculture water return pipes 14 are connected to multiple independent circulating aquaculture ponds 3 respectively.
[0026] The aquaculture water physical filtration module 9 can be a single-layer filter structure or a multi-layer filter structure. For easy replacement, the filter module 9 can be designed as a drawer-type installation method. There is an insertion interface on the side wall of the aquaculture water treatment tower. The aquaculture water physical filtration module 9 is inserted into the aquaculture water treatment tower through the insertion interface. When it needs to be replaced, the aquaculture water physical filtration module 9 can be directly pulled out of the aquaculture water treatment tower.
[0027] Specifically, the biofilm treatment module 10 includes a support net spaced from bottom to top, on which algae are attached. In the aquaculture water treatment tower, as the aquaculture water passes through each support net in sequence, the algae can absorb harmful substances such as ammonia and phosphorus in the aquaculture water and produce a large amount of dissolved oxygen, thereby improving the water quality.
[0028] The top of the aquaculture water treatment tower 2 is equipped with a probiotic dosing device 15, which is used to dispense probiotics into the aquaculture water treatment tower. The probiotic dosing device 15 includes a probiotic storage box 16, a probiotic discharge control cylinder 17, a dosing pipe 18, a probiotic discharge control screw 19, and a servo motor 20. The probiotic discharge control cylinder 17 is placed horizontally, with one end connected to the bottom side of the probiotic storage box 16. One end of the probiotic discharge control screw 19 extends into the probiotic discharge control cylinder 17, and the other end of the probiotic discharge control screw 19 is connected to the output shaft of the servo motor 20. The bottom of the cylinder wall of the probiotic discharge control cylinder 17 is provided with a probiotic outlet 21. The upper end of the dosing pipe 18 is connected to the probiotic outlet 21, and the lower end of the dosing pipe 18 extends from the top of the aquaculture water treatment tower 2 into the aquaculture water treatment tower 2.
[0029] It also includes a control system, which includes a controller 22, an ammonia nitrogen sensor 23 for aquaculture water, and a pH sensor 24 for aquaculture water. The ammonia nitrogen sensor 23 and the pH sensor 24 for aquaculture water are installed in each of the independent circulating water aquaculture ponds 3. The ammonia nitrogen sensor 23 and the pH sensor 24 for aquaculture water transmit information to the controller 22. The controller 22 regulates the water pump 13 and the servo motor 20 in the probiotic dosing device.
[0030] The control system also includes an aquaculture water temperature sensor 25. Each of the independent circulating aquaculture ponds 3 is equipped with the aquaculture water temperature sensor 25. Each of the aquaculture water return pipes 14 is equipped with an electric heater 26. The electric heater 26 is used to heat the aquaculture water. The aquaculture water temperature sensor 25 transmits the aquaculture water temperature information in the independent circulating aquaculture pond 3 to the controller 22. The controller 22 regulates the electric heater 26.
[0031] The control system also includes a dissolved oxygen sensor 27 for aquaculture water. Each independent recirculating aquaculture pond 3 is equipped with a blower 29, an aeration pipe 28, and the dissolved oxygen sensor 27. The blower 29 supplies air to the aeration pipe 28, which is used to increase the oxygen in the aquaculture water in the independent recirculating aquaculture pond 3. The dissolved oxygen sensor 27 transmits the dissolved oxygen content of the aquaculture water in the independent recirculating aquaculture pond 3 to the controller 22, which regulates the blower 29.
[0032] The top of the typhoon-resistant sunroom 1 is equipped with a solar panel 31, which is used to charge the battery 33 in the electrical control box 32 inside the typhoon-resistant sunroom 1. The battery 33 provides power to the control system, the servo motor 20, the water pump 13 and the blower 29.
[0033] An emergency power generation device 34 is also provided inside the typhoon-resistant sunroom 1, which is used to charge the storage battery 33.
[0034] like Figure 4 , 5 As shown in this embodiment, multiple annular aeration pipes 28 are provided on the bottom surface of the independent recirculating aquaculture tank 3. The multiple annular aeration pipes 28 are arranged in concentric circles. Multiple aeration heads 30 are distributed on the aeration pipes 28. The aeration heads 30 face the bottom surface of the independent recirculating aquaculture tank 3 and are inclined towards the center of the independent recirculating aquaculture tank. The aeration heads 30 blow the garbage such as feed and excrement deposited on the bottom surface of the recirculating aquaculture tank 3 towards the center of the independent recirculating aquaculture tank 3. Finally, they are collected in the conical sludge collection tank 5 at the bottom of the aquaculture water treatment tower 2 through the aquaculture water discharge pipe 12. Under the action of the aquaculture water physical filtration module 9, the garbage such as mud, feed, and excrement will not flow upward with the aquaculture water.
[0035] This application has the following characteristics:
[0036] Firstly, each independent recirculating aquaculture pond is individually connected to the aquaculture water treatment tower, which not only significantly reduces the water circulation flow and energy consumption by 40%, but also improves the sensitivity of regulation and the efficiency of water quality control, thereby increasing aquaculture efficiency. The production capacity per unit area is more than 5 times that of the traditional model, and the seedling survival rate is ≥95%. It is also eco-friendly, featuring zero wastewater preparation and reduced drug use.
[0037] Secondly, each independent recirculating aquaculture pond and its aquaculture water treatment tower are housed in a typhoon-resistant sunroom to ensure that the water quality in the aquaculture ponds is not affected by wind and rain.
[0038] Third, the water treatment module is integrated into a single aquaculture water treatment tower, and the various independent circulating aquaculture ponds are arranged around the aquaculture water treatment tower. This not only reduces the land area occupied and makes the overall layout more reasonable and compact, but also allows for centralized treatment of waste in the aquaculture water.
[0039] Fourth, a control system was adopted, which can monitor and precisely regulate the aquaculture water in real time, solving the problem that water quality regulation in existing technologies relies on human experience, thereby improving the survival rate of seedlings.
[0040] Fifth, the modular recirculating aquaculture system: a three-stage purification process involving physical filtration, biofilm, and probiotics. The physical filtration module filters out sediment, uneaten feed, excrement, and other waste from the aquaculture water, collecting it in a cone-shaped collection tank. The biofilm module, with its attached microorganisms such as bacteria and algae, absorbs harmful substances like ammonia and phosphorus from the water and produces a large amount of dissolved oxygen, thus improving water quality. This is crucial for maintaining a stable aquaculture environment and preventing disease outbreaks.
[0041] Probiotics enhance the immune system of aquatic animals by regulating the balance of gut microbiota, inhibiting the growth of harmful bacteria, and promoting the reproduction of beneficial bacteria. Probiotics can also decompose organic matter in aquaculture water, such as uneaten feed and excrement, reducing the levels of harmful substances like ammonia nitrogen, nitrite, and hydrogen sulfide, thus improving water quality. When dissolved oxygen levels are below 4 mg / L, the aeration device automatically activates; when ammonia nitrogen concentration exceeds the standard, the probiotic dosing device is activated to add probiotics to the circulating aquaculture water.
[0042] Sixth, energy synergy management: solar power supply and emergency energy storage systems reduce energy consumption and ensure continuous system operation.
[0043] In addition, based on the above embodiments, the controller can also use an IoT-based sensor network and AI algorithms to dynamically optimize dissolved oxygen, pH, and feeding strategies.
[0044] Furthermore, those skilled in the art can combine and integrate the different embodiments or examples described herein, as well as the features of those different embodiments or examples, without contradiction. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
