[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A factory-scale recirculating fish farming device includes a base 1, a culture tank 2 fixedly connected to the top of the base 1, a disinfection component 4 installed inside the culture tank 2, and a circulation component 5 installed outside the culture tank 2.

[0027] The disinfection component 4 includes a disinfection shell 401 fixedly connected inside the culture tank 2. The bottom of the disinfection shell 401 has a water inlet 402. A spiral guide plate 403 is provided on the bottom side inside the disinfection shell 401. An ozone distributor 404 is provided on the top of the spiral guide plate 403. A nano-catalytic mesh 405 is provided on the top of the ozone distributor 404. An ultraviolet lamp 406 is fixedly connected to the inner side of the top of the disinfection shell 401. The ultraviolet lamp 406 is located on top of the nano-catalytic mesh 405. A drain pipe 407 is connected to the top of the disinfection shell 401.

[0028] In this embodiment: the water source to be disinfected enters the aquaculture pond through the inlet 402 at the bottom of the disinfection shell 401, and then rises spirally under the guidance of the spiral guide plate 403. The spiral guide plate 403 allows the water flow to fully contact the subsequent disinfection components. As the water flows upward, it reaches the ozone distributor 404, which releases ozone into the water. Ozone has strong oxidizing properties and can quickly react with pathogens such as bacteria and viruses in the water, as well as organic matter, destroying the cell structure of pathogens and oxidizing and decomposing organic matter, thus achieving preliminary disinfection and purification of the water, reducing the microbial content and organic pollutant concentration in the water. The ozone-disinfected water continues to rise, passing through the nanocatalytic mesh 405, where the nanocatalyst... Under the combined action of ozone and water flow, net 405 further catalytically degrades residual harmful substances in the water. The special properties of nanomaterials enhance the activity of chemical reactions, further decomposing some organic pollutants that are difficult to be completely oxidized by ozone into harmless substances, thus improving the purification level of the water. The water flows up to the ultraviolet lamp 406, which emits ultraviolet light. Ultraviolet light can destroy the structure of pathogens in the water, causing them to lose their ability to reproduce and infect, and further kill residual bacteria, viruses and other microorganisms in the water, ensuring that the water treated by disinfection component 4 meets the standards for ecological aquaculture. Then, it flows out from the drain pipe 407 at the top of the disinfection shell 401 and returns to the aquaculture pond.

[0029] Specifically, such as Figure 3 As shown, the circulation assembly 5 includes a filter 501 fixedly connected inside the culture tank 2, a circulation drain 502 connected to the outside of the filter 501, a main circulator 503 connected to the outside of the filter 501, and a circulation pump 504 fixedly connected to the top of the base 1. The inlet end of the circulation pump 504 is connected to the main circulator 503.

[0030] Specifically, such as Figure 3 As shown, the output end of the circulating pump 504 is connected to the delivery pipe 505, and the outer side of the delivery pipe 505 is connected to the annular main pipe 506.

[0031] Specifically, such as Figure 3As shown, the annular manifold 506 is fixedly connected to the culture tank 2, and the outer side of the annular manifold 506 is connected to the delivery head 507.

[0032] In this embodiment: When the factory-scale recirculating fish farming system is running, firstly, water from the aquaculture pond flows into the filter 501 located inside the culture pond 2. The filter 501 traps fish feces and uneaten feed, thus initially purifying the water. The water that has undergone initial filtration flows out through the circulation drain 502 on the outside of the filter 501 and enters the main circulation device 503. The main circulation device 503 acts as a collector and buffer, concentrating the filtered water from various locations to provide a stable water source for subsequent circulation. Next, the circulation pump 504 at the top of the base 1 starts, drawing water from the main circulation device 503 at its inlet. When the circulation pump 504 is working, it uses mechanical power to... The water is pressurized to give it sufficient energy to enter the delivery pipe 505. The water flows in the delivery pipe 505, and the annular main pipe 506 connected to the outside of the delivery pipe 505 collects this water. The annular main pipe 506 surrounds the culture tank 2 and is fixedly connected to the culture tank 2. The delivery head 507 connected to its outside evenly sends the water in the annular main pipe 506 back into the culture tank 2, so that the culture water is constantly circulating. This avoids problems such as uneven dissolved oxygen and accumulation of harmful substances in the water body, prevents local water quality deterioration, creates a stable and suitable living environment for fish, conforms to the natural living habits of fish, helps fish grow healthily, and improves the yield and quality of aquaculture.

[0033] Specifically, such as Figure 5 As shown, a monitoring seat 6 is provided on the outside of the delivery pipe 505, a water flow monitor 7 is provided on the top of the monitoring seat 6, and a control valve 8 is provided on the front side of the monitoring seat 6.

[0034] Specifically, such as Figure 4 As shown, a temperature sensor 9 is installed inside the disinfection housing 401, and a signal transmitter 10 is installed on the outside of the disinfection housing 401. The signal transmitter 10 is electrically connected to the temperature sensor 9.

[0035] In this embodiment: By setting up a monitoring seat 6, a water flow monitor 7, and a control valve 8, after the circulating pump 504 pressurizes water and sends it into the delivery pipe 505, the water flows through the monitoring seat 6. At this time, the water flow monitor 7 monitors the water flow velocity in the delivery pipe 505 in real time and feeds back the data in real time. If the water flow velocity is abnormal, such as too fast or too slow, the operator can operate the control valve 8 on the front side of the monitoring seat 6 to control the water flow rate by adjusting the valve opening, thereby regulating the water flow velocity to keep it within a suitable range. This ensures the stable operation of the circulating water system, avoids excessive or insufficient pipe pressure due to abnormal flow velocity, reduces the risk of system failure, and at the same time, a suitable water flow velocity creates a more stable living environment for fish, which is in line with the fish's living habits, conducive to the healthy growth of fish, and improves... To improve aquaculture efficiency, by installing a temperature sensor 9 and a signal transmitter 10, the temperature sensor 9 inside the disinfection housing 401 continuously monitors the internal water temperature when the disinfection component 4 is working, and converts the temperature data into electrical signals. These electrical signals are transmitted through connecting lines to the signal transmitter 10 installed on the outside of the disinfection housing 401. The signal transmitter 10 then remotely transmits the data to the staff's monitoring terminal. The staff can obtain the temperature information inside the disinfection housing 401 in real time. When abnormal temperature fluctuations occur, the staff can adjust the power of the ultraviolet lamp 406 or the working frequency of the ozone distributor 404 in a timely manner to maintain a suitable disinfection temperature environment, ensure that the circulating water is fully and effectively disinfected, protect the hygiene and safety of the aquaculture water, and reduce the risk of fish infection.

[0036] Specifically, such as Figure 2 As shown, a residual ozone decomposition device 3 is fixedly connected to the top side inside the disinfection housing 401, and the residual ozone decomposition device 3 is located at the bottom of the drain pipe 407.

[0037] Specifically, such as Figure 1 As shown, an inspection ladder 11 is fixedly connected to the top of the base 1, and an anti-slip pad 12 is provided on the top of the inspection ladder 11. The anti-slip pad 12 is made of rubber.

[0038] In this embodiment: By setting up a residual ozone decomposition device 3, the water that has undergone ozone disinfection, nanocatalysis, and ultraviolet disinfection will first pass through the residual ozone decomposition device 3 located at the bottom of the drain pipe 407 before flowing out from the top of the disinfection shell 401. The catalyst inside the residual ozone decomposition device 3 reacts chemically with the residual ozone in the water, decomposing the ozone into oxygen. The decomposed gas and the treated water are discharged together from the drain pipe 407 and re-enter the circulation system to prevent excessive ozone from harming the health of fish and affecting their growth and survival. By setting up an inspection ladder 11 and anti-slip mats 12, during the daily operation of the factory-style recirculating fish farming device, the staff needs to regularly inspect, maintain, and debug the device. At this time, the staff can climb to the top of the device through the inspection ladder 11 on the top of the base 1. The rubber anti-slip mats 12 increase the friction between the staff's shoes and the inspection ladder 11, effectively preventing the staff from slipping and ensuring the safety of the staff during climbing and walking, so that the staff can safely and smoothly complete various inspection and maintenance work.

[0039] Working Principle: When using the factory-scale recirculating fish farming device, the wastewater generated from fish farming flows from the culture tank 2 into the filter 501. The filter 501 filters out larger impurities in the wastewater. The preliminarily purified water flows into the main recirculator 503 through the circulating drain 502. The circulating pump 504 draws water from the main recirculator 503 and pressurizes it, causing the water to enter the delivery pipe 505. On the delivery pipe 505, the water flow monitor 7 monitors the water flow speed in real time. If the water flow speed is abnormal, it can be adjusted through the control valve 8. The water in the delivery pipe 505 then enters the annular main pipe 506, which surrounds the outside of the culture tank 2. The delivery head 507 on it sends the water back to the culture tank 2, realizing the water circulation and providing a stable aquatic environment for the fish. The wastewater inside the culture tank 2 flows in from the inlet 402 at the bottom of the disinfection shell 401. Guided by the spiral guide plate 403, it rises in a spiral shape, prolonging the residence time in the disinfection shell 401. During the process, the ozone distributor 404 releases ozone, which oxidizes bacteria and organic matter in the water, thus disinfecting and purifying the water. At this time, the nano-catalytic mesh 405, under the combined action of ozone and water flow, further catalyzes and degrades harmful substances in the water. When the water rises to the ultraviolet lamp tube 406, the ultraviolet light destroys the structure of pathogens in the water, disinfecting the water again. The disinfected water flows out from the top drain pipe 407 and returns to the circulation system. The temperature sensor 9 inside the disinfection shell 401 monitors the internal water temperature in real time, and the data is sent out through the signal transmitter 10 so that the staff can understand the situation and make adjustments. The residual ozone decomposition device 3 at the bottom of the drain pipe 407 decomposes the residual ozone in the water into oxygen, preventing ozone from harming fish. At the same time, the inspection ladder 11 on the top of the base 1 facilitates the staff to conduct daily inspections and maintenance of the device, and its rubber anti-slip pad 12 can prevent the staff from slipping and ensure their safety.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
