Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture water bodies, in particular to a dual constant temperature hot water system used in aquaculture. Background Art

[0002] At present, my country's recirculating aquaculture industry has entered a stage of rapid development. Recirculating aquaculture has generally received attention from production companies. Due to its low pollution, controllable breeding environment, and hygienic characteristics of aquatic products, industrial recirculating aquaculture has received high attention from all walks of life in aquaculture and support from the government.

[0003] In the recirculating aquaculture system, water temperature is a very important water quality parameter for aquatic organisms. It can directly affect the physiological behavior of aquatic organisms such as fish and shrimp, and will also indirectly affect other water quality parameters in the same environment. In terms of operation economy, water temperature control consumes a lot of energy, which will also increase operation costs and increase the economic burden of enterprises. Therefore, the design effect of the water temperature control system will ultimately seriously affect the aquaculture output, the quality of aquatic products and the total revenue of the enterprise.

[0004] Most of my country's recirculating aquaculture systems use electricity or fuel to control the temperature of the water in the breeding pond, which is not only environmentally friendly, but also generally has the characteristics of high energy consumption. In addition, controlling the temperature of the water in the breeding pond by consuming fuel efficiency will also have a certain impact on the surrounding environment. Excessive waste of energy will also lead to increased breeding costs and burdens on breeding companies. The problem of high energy consumption in the temperature control link of breeding water has become a bottleneck restricting the development of industrialized recirculating aquaculture. Moreover, most of the constant temperature water equipment on the market currently has only one temperature control method, which cannot meet the breeding requirements of some breeding industries. Utility Model Content

[0007] The air energy heat pump 3 comprises an air compressor 31, a condenser 32, an evaporator 33, and a throttling device 34.

The tap water source 1 enters from the evaporator 33 in the air energy heat pump 3 and flows out from the condenser 32. The tap water source 1 can be heated to a predetermined temperature by the air energy heat pump 3.

By setting the valve as a solenoid valve, it is convenient for the intelligent control system to perform automatic control, and the degree of intelligence is high.

[0009] The first circulation pump 15 and the second circulation pump 16 are connected to the bottom of the breeding pond 6, which is more conducive to the circulation of water in the breeding pond 6.

[0010] There are two constant temperature water tanks 5, and a heat exchanger 17 is arranged inside each constant temperature water tank 5. The heat exchanger 17 can be used to exchange heat for hot water, thereby adjusting the water temperature required by the user.

[0011] The heat exchanger 17 is a low-frequency micro-motion turbulent heat exchanger. The heat exchanger 17 is a low-frequency micro-motion turbulent heat exchanger, and the material is one or more of copper, nickel platinum copper, stainless steel or titanium tube. In this way, the electricity in the constant temperature system does not come into direct contact with the pool water, and there is no risk of leakage, which provides system safety.

[0012] After adopting the above technical solution, the beneficial effects of the utility model are:

[0013] 1. The utility model uses solar energy, air energy heat pump clean new energy and other equipment in the system to replace electric heating and cooling towers to keep the water in the aquaculture pond at a constant temperature, which fully saves energy.

The two constant temperature water tanks can be set to two different temperatures according to the user's requirements and the system can be customized to reduce the investment cost and ensure that the water temperature is constant without affecting each other. A heat exchanger 17 is arranged inside each constant temperature water tank 5. By setting the heat exchanger 17, hot water can be heat exchanged, so as to adjust the water temperature required by the user. The heat exchanger 17 is a low-frequency micro-motion turbulent heat exchanger. The heat exchanger 17 adopts a low-frequency micro-motion turbulent heat exchanger, and the material is one or more of copper, nickel-platinum-copper, stainless steel or titanium tube. In this way, the electricity in the constant temperature system does not come into direct contact with the pool water, and there is no risk of leakage, thereby providing system safety. The constant temperature water tank 5 is connected to the breeding pool 6 through a pipeline. A water temperature probe 7 is arranged inside the breeding pool 6. The water temperature probe 7 can be multiple and installed at different positions of the breeding pool 6. For example, different heights or different corners. In this way, the water temperature at different positions in the breeding pool 6 can be detected, and the water temperature information in the breeding pool 6 can be obtained more accurately. The water temperature probe 7 is connected to the temperature control device 8, and the other end of the temperature monitoring and control device 8 is connected to the air energy heat pump 3.

[0020] The air energy heat pump 3 comprises an air compressor 31, a condenser 32, an evaporator 33, and a throttling device 34. The air compressor 31 is connected in series with the condenser 32, the evaporator 33, and the throttling device 34. The tap water source 1 enters from the evaporator 33 in the air energy heat pump 3 and flows out from the condenser 32. The tap water source 1 can be heated to a predetermined temperature by the air energy heat pump 3.

[0021] In this embodiment, an intelligent control system is adopted, and the intelligent control system includes a controller module and a touch screen display.

The temperature monitoring and control device 8 outputs a control signal to the air energy heat pump 2 and controls its operation.

The water in the constant temperature water tank 5 is then circulated with the water in the breeding pool 6 through the first circulation pump 15 and the second circulation pump 16 to keep the water in the breeding pool 6 at a constant temperature.
