Description

Technical Field

[0001] The utility model relates to the technical field of fish pond oxygenation, in particular to a structure of a three-stage aeration fish pond. Background Art

[0002] A fish pond aerator is a device used to increase the dissolved oxygen content in the water of a fish pond. It introduces oxygen from the air into the water to provide more oxygen for fish to breathe, so as to maintain the normal physiological functions of the fish. The use of a fish pond aerator can effectively increase the dissolved oxygen content of the water in the fish pond, improve the living environment of fish, and promote the growth and reproduction of fish. The use of aerators is particularly important when the fish density is high, the temperature is high, there is more bait, or the water pollution is serious. In addition, aerators can also increase the redox potential of the water, help regulate the metabolism of the fish, and reduce the occurrence of fish diseases. A jet aerator is a type of aerator, a device that injects oxygen into the water through jet technology. The device mixes oxygen with water and forms fine bubbles, and then injects them into the water, thereby increasing the dissolved oxygen content in the water. Aerators usually use high-pressure pumps or gas compressors to generate airflow, and inject the airflow into the water in the form of a jet through a specially designed nozzle. This injection method can make oxygen dissolve better in the water and increase the oxygen content of the water. Jet aerators can effectively increase the dissolved oxygen content in water, improve the oxygen supply in water, and promote the growth and metabolism of organisms in water. Jet aerators use high-pressure pumps or gas compressors to generate airflow, which consumes less energy than traditional oxygenation methods. The operation of the aerator is relatively simple, and only requires connecting the air source and water source, and performing certain adjustments and maintenance.

[0003] At present, the jet aerators on the market generally use a single ejector with a simple structure and low oxygenation efficiency. If the fish density is high, the oxygenation effect may not be ideal and the water may be insufficiently supplied with oxygen. Summary of the invention

[0004] The utility model aims to provide a three-stage aeration fish pond structure with scientific and reasonable structure, simple and quick installation, high oxygenation efficiency and low cost in view of the defects and shortcomings of the prior art.

[0005] In order to solve the problems existing in the background technology, the utility model adopts the following technical solutions: a structure of a three-stage aerated fish pond, including a fish pond, a filter, a water pump, an air source, a first ejector, and a second ejector. The water source of the fish pond is connected to the water inlet of the filter and the water pump through pipes respectively, the water outlet of the water pump is connected to the water inlet of the first ejector and the water inlet pipe of the second ejector in parallel respectively, the air inlet of the first ejector is connected to the air source, the water-gas mixing port of the second ejector is connected to the ejection port pipe of the first ejector, and the ejection port of the second ejector is connected to the return port pipe of the fish pond.

[0006] After adopting the above technical scheme, the utility model adopts a three-stage aeration structure: the first stage aeration is a jet mixing of the water source and the air source of the first ejector; the second stage aeration is a gas-liquid mixture formed by the first ejector and then mixed for the second time in the water-gas mixing port of the second ejector, so as to fully mix the air (oxygen, disinfectant or ozone) and water molecules and improve the aeration efficiency. The two aerations make the mixing more complete and the oxygen content in the water higher; the third stage aeration is that the gas-liquid mixture after the two aerations is finally ejected to the reflux port of the fish pond through the ejection port of the second ejector, and produces a third aeration reaction with the water body of the fish pond. The three-stage aeration structure of the utility model greatly improves the oxygen supply efficiency of the fish pond, can more effectively help improve the water environment, promote the growth and reproduction of aquatic organisms, improve the breeding effect, reduce the accumulation of pollutants, and enhance the self-purification ability of the water body; the utility model is also suitable for various water environments, such as ponds, lakes, aquaculture ponds, swimming pools, etc., and one or more structures of the utility model can be set at different locations according to the size of the water environment to increase the oxygen content of the water body and effectively improve the water quality. It has a wide range of applications: for example, it is used in water ecological restoration, aquaculture, water pollution control and water disinfection and purification.

[0007] Furthermore, a thermostat is provided between the water pump and the first ejector and the second ejector.

[0008] After adopting the above technical solution, the thermostat provided by the utility model is composed of a temperature sensor and a heater. The temperature sensor can monitor the water temperature of the fish pond and send a signal to the controller. The controller controls the working state of the heater according to the set temperature value and the actual water temperature to achieve the purpose of constant temperature. The fish pond thermostat can adjust the power and working time of the heater according to different needs to keep the water temperature of the fish pond within an appropriate range and provide a good living environment and breeding conditions.

[0009] Furthermore, the gas source is one of an air source, an oxygen source, an ozone source, and a disinfectant.

[0010] After adopting the above technical scheme, the gas source of the utility model can be used in water oxidation, disinfection and circulation treatment processes by delivering air, oxygen, ozone or disinfectants according to actual needs, thereby further improving the water quality treatment effect.
