Description

Technical Field

[0001] This utility model relates to the technical field of fish egg incubation devices, and in particular to an incubation device suitable for salmon and trout eggs. Background Technology

[0002] Salmon and trout are important cold-water economic fish species that occupy a significant position in aquaculture. Their egg hatching process is extremely sensitive to environmental conditions, directly affecting the hatching rate and the quality of the fry. Therefore, salmon and trout egg hatching devices are needed to assist in the hatching of salmon and trout eggs.

[0003] Currently, most existing salmon and trout egg hatching devices suffer from the following technical problems;

[0004] In terms of water quality control, it is difficult to precisely maintain suitable water flow rate, dissolved oxygen level, and water temperature for salmon and trout egg hatching. For example, unstable water flow rate may cause localized accumulation of fish eggs, affecting oxygen exchange and thus reducing the hatching rate; excessive fluctuations in water temperature can cause abnormal egg development and increase the proportion of deformed fry. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a suitable salmon and trout egg hatching device, solving the problem that existing salmon and trout egg hatching devices are not easy to control the water temperature, which affects the hatching of salmon and trout eggs.

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

[0007] A device for hatching salmon and trout eggs includes a frame, a support frame fixedly connected to the top of the frame, a raw water inlet pipe fixedly connected to the side wall of the frame, one end of the raw water inlet pipe connected to a raw water tank, a heater / cooler fixedly installed on the inner bottom surface of the frame, an electrical control box installed on the surface of the frame, a guide pipe fixedly connected to one of the outlets of the heater / cooler, a condensate drain pipe fixedly connected to the drain outlet of the heater / cooler, eight hatching trays slidably connected to the support frame, the hatching trays being divided into two groups, each group containing four hatching trays, a circulating water pump fixedly installed on the inner bottom surface of the raw water inlet pipe, and the outlet of the circulating water pump fixedly connected to the outlet of the heater / cooler via a pipe.

[0008] Preferably, a drain pipe is fixedly connected to the end of the guide pipe away from the heating / cooling unit, and drain valves are fixedly connected to both sides of the guide pipe.

[0009] Preferably, the water drain pipe is C-shaped, with its two outlets facing the two sets of hatching trays respectively. The hatching trays are equipped with overflow outlets, through which the upper hatching tray flows excess water to the lower hatching tray.

[0010] Preferably, a biological treatment tank is fixedly connected to the inner bottom surface of the frame, and a treatment tank drain pipe is fixedly connected to the upper half of the frame near the circulating water pump. The end of the treatment tank drain pipe away from the biological treatment tank passes through the biological treatment tank and faces outward from the frame.

[0011] Preferably, an oxygenation pump is fixedly connected to the inner wall of the frame, the end of the raw water inlet pipe away from the raw water tank is fixedly connected to the oxygenation pump, and an oxygen supply pipe is fixedly connected to the side of the oxygenation pump near the biological treatment tank, with the end of the oxygen supply pipe away from the oxygenation pump located inside the biological treatment tank.

[0012] Preferably, the inlet of the circulating water pump is fixedly connected to a diversion pipe, the middle section of which is fixedly connected to a pump tank suction valve, an isolation valve, and a treatment tank drain valve. The diversion pipe is fixedly connected to the treatment tank drain pipe through a pipeline between the isolation valve and the treatment tank drain valve. A pipeline is connected between the pump tank suction valve and the isolation valve. The end of the pipeline away from the diversion pipe is fixedly connected to the biological treatment tank, and the end of the diversion pipe away from the circulating water pump is fixedly connected to the biological treatment tank.

[0013] Preferably, a pressure relief valve is fixedly connected to the middle section of the guide pipe, with the end of the pressure relief valve away from the guide pipe facing the opening of the biological treatment tank, and a third valve is fixedly connected to the middle section of the guide pipe.

[0014] Preferably, a first valve is fixedly connected to the guide pipe between the third valve and the raw water inlet pipe, and a second valve is fixedly connected to the guide pipe on the side of the third valve away from the pressure relief valve. An ultraviolet sterilizer is fixedly connected to the ends of the first valve and the second valve away from the guide pipe.

[0015] Preferably, a collection plate is fixedly connected to the top surface of the frame, and a drain pipe is fixedly connected to the bottom surface of the collection plate. The outlet of the drain pipe faces the biological treatment tank. The collection plate is used to collect the wastewater overflowing from the hatching tray and guide it to the biological treatment tank through the drain pipe. Valves are installed on both the raw water inlet pipe and the condensate drain pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. This application introduces water into the aerator pump through the raw water inlet pipe. The aerator pump, in conjunction with the aerator pipe, discharges oxygenated water into the biological treatment tank. The water in the biological treatment tank flows through the pipe between the isolation valve and the treatment tank drain valve to the diversion pipe, which then guides it to the circulating water pump. The circulating water pump then pumps the water into the heating and cooling unit. The heating and cooling unit, in conjunction with the guide pipe and the drain pipe, adds temperature-regulated water to each hatching tray. By incorporating the heating and cooling unit, the temperature of the circulating water can be adjusted to a suitable temperature for salmon and trout egg growth, thus solving the problem of existing salmon and trout egg hatching devices having difficulty controlling water temperature, which affects the hatching of salmon and trout eggs.

[0018] II. This application, by incorporating an ultraviolet sterilizer, allows the valves on the raw water inlet pipe and condensate drain pipe to be normally open when the water needs to be sterilized. The treatment tank drain valve, isolation valve, and third valve are closed, while the pump tank suction valve, first valve, second valve, and two drain valves are opened. At this time, the water flows through the ultraviolet sterilizer and is sterilized by ultraviolet light, giving this application the effect of sterilizing the water flow. Furthermore, this application allows for the selection of sterilization or non-sterilization operations, adapting to different stages of fish egg growth and thus possessing high applicability.

[0019] III. This application, by incorporating an oxygenation pump, a biological treatment tank, and a circulating water pump, allows water to be added to the oxygenation pump via a raw water inlet pipe. The oxygenation pump, in conjunction with an oxygenation pipe, discharges oxygenated water into the biological treatment tank. Water in the biological treatment tank flows through a pipe between an isolation valve and the treatment tank's drain valve to a diversion pipe, which then guides it to the circulating water pump. The circulating water pump then pumps the water into a heating / cooling unit. This unit, along with a diversion pipe and a drain pipe, adds temperature-regulated water to each hatching tray. A drain valve controls the flow of water through the drain pipe. Water discharged into the hatching trays flows down through overflow outlets, is ultimately collected by a collection plate, and is guided into the biological treatment tank via a drain pipe, thus achieving water purification. The biological treatment tank is circulated because a treatment tank drain pipe is fixedly connected to the side of the biological treatment tank near the circulating water pump. When the water level in the biological treatment tank is higher than the treatment tank drain pipe, it will be discharged through the treatment tank drain pipe. The first valve, the second valve, and the ultraviolet sterilizer installed in the middle section of the guide pipe are used to disinfect the water. The condensate drain pipe connected to the raw water inlet pipe, together with the oxygen supply pipe, is used to oxygenate the water inside the biological treatment tank, increase the dissolved oxygen in the water, maintain the survival needs of fish eggs and nitrifying bacteria, and improve the treatment efficiency of the biological treatment tank. This application has the functions of water circulation, increasing water oxygen content, and cultivating nitrifying bacteria, which can be adapted to different stages of fish egg growth, making this application highly applicable.

[0036] The drain pipe 16 is C-shaped, with its two outlets facing the two sets of hatching tray bodies 23 respectively. The hatching tray body 23 is provided with an overflow port and an overflow trough at the top. The hatching tray body 23 has a drain hole at a position away from the overflow port in the overflow trough. The upper hatching tray body 23 uses the overflow port, overflow trough and drain hole to direct excess water to the lower hatching tray body 23.

[0037] A biological treatment tank 22 is fixedly connected to the inner bottom surface of the frame 17. A treatment tank drain pipe 6 is fixedly connected to the upper half of the frame 17 near the circulating water pump 19.

The end of the raw water inlet pipe 1 away from the raw water tank is fixedly connected to the oxygenation pump 20. An oxygen supply pipe is fixedly connected to the side of the oxygenation pump 20 near the biological treatment tank 22. The end of the oxygen supply pipe away from the oxygenation pump 20 is located inside the biological treatment tank 22.

[0039] The inlet of the circulating water pump 19 is fixedly connected to a diversion pipe 25. The middle section of the diversion pipe 25 is fixedly connected to a pump pool suction valve 5, an isolation valve 4, and a treatment pool drain valve 3. The diversion pipe 25 is fixedly connected to the treatment pool drain pipe 6 through a pipe between the isolation valve 4 and the treatment pool drain valve 3. A pipe is connected between the pump pool suction valve 5 and the isolation valve 4. The end of the pipe away from the diversion pipe 25 is fixedly connected to the biological treatment pool 22. The end of the diversion pipe 25 away from the circulating water pump 19 is fixedly connected to the biological treatment pool 22.

[0040] A pressure relief valve 11 is fixedly connected to the middle section of the guide pipe 15. The end of the pressure relief valve 11 away from the guide pipe 15 faces the opening of the biological treatment tank 22. A third valve 9 is fixedly connected to the middle section of the guide pipe 15.

[0041] A first valve 7 is fixedly connected between the third valve 9 and the raw water inlet pipe 1 in the guide pipe 15. A second valve 8 is fixedly connected to the guide pipe 15 on the side of the third valve 9 away from 11. An ultraviolet sterilizer 24 is fixedly connected to the ends of the first valve 7 and the second valve 8 away from the guide pipe 15.

[0042] A collection plate 14 is fixedly connected to the top surface of the frame 17, and a drain pipe 18 is fixedly connected to the bottom surface of the collection plate 14. The outlet of the drain pipe 18 faces the biological treatment tank 22. The collection plate 14 is used to collect the wastewater overflowing from the hatching tray body 23 and guide it to the biological treatment tank 22 through the drain pipe 18. Valves are installed on both the raw water inlet pipe 1 and the condensate drain pipe 2.

[0043] Working principle:

[0044] In the first step, water is added to the aeration pump 20 through the raw water inlet pipe 1. The aeration pump 20, in conjunction with the aeration pipe, discharges oxygenated water into the biological treatment tank 22. The water in the biological treatment tank 22 flows to the diversion pipe 25 through the pipe between the isolation valve 4 and the treatment tank drain valve 3. The water is then guided to the circulating water pump 19 through the diversion pipe 25 and pumped into the heating and cooling unit 21. The heating and cooling unit 21, in conjunction with the guide pipe 15 and the drain pipe 16, adds temperature-regulated water to each hatching tray body 23. The drain valve 12 controls the flow of water in the drain pipe 16. The water discharged into the hatching tray body 23 through the drain pipe 16 flows down through the overflow port and is eventually collected. The water is collected by the collection plate 14 and introduced into the biological treatment tank 22 through the drain pipe 18 to achieve water circulation. Because the biological treatment tank 22 is fixedly connected to the treatment tank drain pipe 6 on the side near the circulating water pump 19, when the water level in the biological treatment tank 22 is higher than the treatment tank drain pipe 6, it will be discharged through the treatment tank drain pipe 6. The first valve 7, the second valve 8 and the ultraviolet sterilizer 24 set in the middle section of the guide pipe 15 are used to disinfect the water. The condensate drain pipe 2 connected to the raw water inlet pipe 1, together with the oxygen supply pipe, is used to oxygenate the water inside the biological treatment tank 22, increase the dissolved oxygen in the water, maintain the survival needs of fish eggs and nitrifying bacteria, and improve the treatment efficiency of the biological treatment tank 22.

[0045] The second step is to keep the valves on the raw water inlet pipe 1 and the condensate drain pipe 2 normally open, close the treatment tank drain valve 3, the isolation valve 4 and the third valve 9, and open the pump tank suction valve 5, the first valve 7, the second valve 8 and the two drain valves 12. At this time, the water will flow through the ultraviolet sterilizer 24 and be sterilized by ultraviolet light.

[0046] Third, when the water in this application is not disinfected by the ultraviolet sterilizer 24, keep the valves on the raw water inlet pipe 1 and the condensate drain pipe 2 in the normally open state, close the treatment tank drain valve 3, the isolation valve 4, the first valve 7 and the second valve 8, and open the pump tank suction valve 5, the third valve 9 and the two drain valves 12. At this time, the water flows directly through the guide pipe 15 and through the third valve 9 without passing through the ultraviolet sterilizer 24. At this time, the water is not disinfected by ultraviolet light.

[0047] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
