High-pressure gas mixing type water aerator

Abstract

The invention discloses a high-pressure gas mixing type water aerator which comprises a high-pressure gas storage tank and a gas mixing device. The gas mixing device is connected with the high-pressure gas storage tank through a connecting pipeline, the gas mixing device comprises a gas inlet pipe and a gas mixing pipe, and a guide chamber, a gas mixing chamber and an exhaust chamber which are sequentially arranged from the top end of the gas mixing pipe downwards are arranged in the gas mixing pipe; the guide chamber, the gas mixing chamber and the exhaust chamber are communicated with one another, and the guide chamber inclines downwards and inwards from the top end of the gas mixing pipe to form an inverted-cone-shaped structure and extends to the gas mixing chamber; and the gas mixing chamber downwards extends to the exhaust chamber from the bottom end of the guide chamber in a cylindrical structure. According to the structure, due to the fact that the guiding chamber is of the inverted-cone-shaped structure, the pressure of air and water entering the guide chamber continuously rises in the downward flowing process, the dissolved amount of oxygen in the air can be increased, and the mixing speed of the air and the water can be increased; and due to the fact that the gas mixing chamber is of the cylindrical structure, the mixing time can be prolonged, and the depth can be increased, so that the air and water mixing effect is better.

Description

technical field [0001] The invention belongs to the field of aquaculture oxygenation devices, and in particular relates to a high-pressure gas-mixing type water body oxygenation machine. Background technique [0002] The oxygen content in water is very important for aquatic organisms, so farmers need to pay attention to the oxygen content in the pond frequently in the aquaculture industry. With the development of science and technology, people are paying more and more attention to the importance of underwater oxygenation. For example, traditional ponds do not have oxygenation machines for underwater oxygenation, which may cause hypoxia in the water and cause slow growth of fish fry. Even death due to lack of oxygen, and modern fish farming generally uses underwater air aerators to achieve the purpose of increasing production and income of fish farming. However, the underwater air aerators currently on the market cannot be operated by remote control, and cannot only detect t...

Problems solved by technology

The technical scheme of the present invention adopts the air decompression nozzle to release air to the bottom of the water, so that to a certain extent, the high-pressure air in the oxygen storage tank is concentrated in the inner space of the hollow cylinder to increase oxygen to the water, and the convection of the water flow is used. Water with high oxygen content is dispersed into the entire breeding area to achieve oxygenation of the entire breeding water area. However, in this patent, only high-pressure gas is released in the hollow cylinder to increase oxygenation, and the convection of water flow is slow, and the efficiency of oxygenation is slow. , the utilization rate of oxygen is low, and it is impossible to measure the oxygen content of water in real time and increase oxygen in time, so it cannot meet the needs of high-density and high-efficiency aquaculture
