Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to specific embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A jet aerator is shown in figure 1 and comprises a water inlet pipe 1, a circulating water nozzle 2, a gas-water mixing chamber 3, an air inlet pipe 4 and an injection piece 5. The circulating water nozzle 2 extends into the air-water mixing chamber 3 from the lower end of the air-water mixing chamber 3 and is communicated with the air-water mixing chamber 3, the water inlet pipe 1 is communicated with the bottom end of the circulating water nozzle 2, so that liquid can uniformly and stably flow through the circulating water nozzle 2 from the water inlet pipe 1 and then enter the air-water mixing chamber 3. The air inlet pipe 4 extends into the air-water mixing chamber 3 from the upper end of the air-water mixing chamber 3 and is communicated with the air-water mixing chamber 3, and the air inlet pipe 4 is used for guiding air into the air-water mixing chamber 3. The plurality of the injection pieces 5 are inserted on the air-water mixing chamber 3, and the injection pieces 5 are used for injecting the mixed solution in the air-water mixing chamber 3 to a preset place. The aperture that circulating water nozzle 2 with jet 5 is connected is less than circulating water nozzle 2 with the aperture that inlet tube 1 is connected to this can make the liquid velocity of flow accelerate, and then produces the negative pressure in making the air water mixing chamber 3, makes the air inhale from air intake pipe 4 and fully mixes.

Specifically, as shown in fig. 1, when the jet aeration treatment is performed, the liquid enters from the water inlet pipe 1 and enters the air-water mixing chamber 3 through the circulating water nozzle 2 along with the guidance of the water inlet pipe 1, because the aperture of the connecting part between the circulating water nozzle 2 and the injection member 5 is smaller than the aperture of the connecting part between the circulating water nozzle 2 and the water inlet pipe 1, the liquid flow rate is increased to form a high-speed and low-pressure liquid flow, negative pressure is generated in the air-water mixing chamber 3, so that the air is sucked into the air inlet pipe 4, the air is violently mixed with the mixed liquid in the air-water mixing chamber 3 to form micro-bubbles, the micro-bubbles are fully contacted with the mixed liquid to dissolve a large amount of molecular oxygen in the mixed liquid, and then the micro-bubbles are jetted out, thereby ensuring the sufficient mixing of air and water, and effectively solving the problems of insufficient aeration amount of the system, low oxygenation efficiency and the like.

In the jet aerator provided in this embodiment, as shown in fig. 1, the plurality of injection pieces 5 are uniformly inserted into the air-water mixing chamber 3, and the injection pieces 5 are arranged to be inclined downward, so that the solution after being sufficiently mixed can be conveniently ejected. Wherein the downward inclination angle of the spraying piece 5 ranges from 30 degrees to 60 degrees, which is beneficial to reducing the splashing of the solution.

In the embodiment of the jet aerator, as shown in fig. 1, the jet aerator is symmetrically arranged, so that the stress balance during work can be ensured, and the position stability can be maintained.

In the jet aerator provided in this embodiment, as shown in fig. 1, the jet aerator is sleeved with a connecting flange for connecting with the outside, so that the jet aerator can be conveniently mounted on the external equipment and used in cooperation with the external equipment.
