[0030] The large circular tube 1, the medium circular tube 2 and the small circular tube 3 are sequentially sleeved to form a concentric circular structure. The large circular tube 1 is longer than the medium circular tube 2, and the outlet of the small circular tube 3 is a certain distance away from the outlet of the medium circular tube 2. The three circular tubes are connected through iron sheets and fixed on the base 4; the small circular tube 3 is connected with one end of the pressure tank 5 through a pipeline. The other end of the pressure tank 5 is connected with the water outlet pipe of the multi-stage dissolved air machine 6 through a pipeline. The water inlet of the multi-stage dissolved air machine 6 is installed with a dirt-proof mesh cover 13, and the multi-stage dissolved air machine 6 is connected with the submersible motor 7 through a coupling. The air inlet of the multi-stage dissolved air machine 6 is installed with a flexible pipe 8, and a stainless steel spring 9 is sleeved outside the flexible pipe 8; the other end of the flexible pipe 8 is installed with a float 10 to ensure that the air inlet is always above the water surface.

[0031] Aeration function

[0032] The multi-stage dissolved air machine 6 inhales air through the flexible pipe 8 and fully mixes the air with the water body to form micro-bubbles. The micro-bubbles are injected into the water body through the pressure tank 5 and the small circular tube 3 to increase the gas-liquid contact area and improve the oxygen dissolution efficiency.

[0033] Working principle: The submersible motor 7 drives the multi-stage dissolved air machine 6 to run, and the water body is sucked into the multi-stage dissolved air machine 6 through the dirt-proof mesh cover 13. The water body treated by the multi-stage dissolved air machine 6 enters the pressure tank 5 and is sprayed out through the small circular tube 3. Due to the design of the concentric circular tube structure, the water body forms a high-speed flow between the small circular tube 3 and the medium circular tube 2, and the flow expansion effect is realized by using the principle of fluid mechanics, which greatly increases the water body driving flow. The flow sprayed out through the small circular tube 3 is Q1, the flow driven by the medium circular tube 2 is Q2, and the flow driven by the large circular tube 1 is Q3. The actual sprayed flow is Q1+Q2+Q3, and the flow speed of the micro-nano bubbles is higher than the sprayed water flow speed, thereby accelerating the water flow speed. Through detection, the actual sprayed flow is about 10 times the flow of the water pump.
