A driving assembly 3 is installed at the upper end of the mixing barrel 2. The driving assembly 3 includes a driving motor 31. A shock-absorbing block 32 is installed between the driving motor 31 and the mixing barrel 2. The output shaft of the driving motor 31 is connected to the impeller 33. The impeller 33 is arranged inside the mixing barrel 2. A through cavity 34 that penetrates the blade is opened on the blade of the impeller 33. The space of the through cavity 34 gradually decreases from the inside to the outside. It can be understood that the size of the through cavity 34 located at the center of the blade is the largest. Towards the two sides of the blade, the size of the through cavity 34 is gradually reduced to form a variable diameter environment. A connecting plate 35 is provided in the through cavity 34 so that the through cavity is divided into two independent parts. The through cavity 34 is connected to the external space. In this embodiment, the impeller 33 is directly formed by lost foam casting and then processed after forming.

[0056] As a specific implementation scheme, the power device is an air pump or a booster pump. For example, an air pump is installed at the tail end of the gas supply device 4, and the air pump pumps the gas in the gas supply device 4 into the mixing barrel 2. Alternatively, a booster pump is installed on the air intake pipe, and the gas in the gas supply device 4 is pumped into the mixing barrel 2. A water pump is installed on the water inlet pipe of the water inlet pipe assembly 6, and the water in the water tank 1 is pumped into the mixing barrel 2.

[0057] As a more specific embodiment, the gas supply device 4 may include a gas tank, which is connected to the gas generating device through a pipeline, so that the gas required for use in this embodiment is stored in the gas tank.

[0058] In the prior art, two liquid level sensors are installed in the water tank 1 to detect whether the water in the water tank 1 has reached the upper limit and the lower limit. This is a common technology in the industry. This embodiment uses this technology and is applied to the water tank 1.

[0059] As the core structure of this embodiment, the mixing cylinder 2 includes a cylinder 21, which is cylindrical or truncated cone-shaped. This embodiment shows the cylindrical cylinder 21 structure, and an upper sealing cover 23 is installed on the upper end of the cylinder 21. The upper sealing cover 23 is connected to the cylinder 21 by bolts, and a gasket is installed between the upper sealing cover 23 and the cylinder 21. The upper end of the shaft of the impeller 33 is connected to the mechanical seal on the upper sealing cover 23 and protrudes from the upper sealing cover 23. The output shaft of the drive motor 31 is connected to the shaft of the impeller 33 through The lower end of the cylinder 21 is a lower sealing cover 24, which is connected to the cylinder 21 by bolts, and a gasket is also installed between the lower sealing cover 24 and the cylinder 21. The lower sealing cover 24 is connected to the distributed air pipe 75 of the air supply pipeline assembly 7 and the liquid outlet reducer 81 of the liquid outlet pipeline assembly 8. From the internal structure of the mixing cylinder 2, in this embodiment, a plurality of disturbing bodies 25 are installed on the inner wall of the cylinder 21. The specific installation scheme adopts welding. The impeller 33 has a flow disturbance hole 26, which penetrates the fluid, so that when the impeller 33 drives the water and gas fluid to rotate and flow, the water and gas are affected by the flow disturbance body 25 and the flow disturbance hole 26, and a large number of fine bubbles are generated under the joint influence of the impeller 33 structure. This matching scheme makes the generation of bubbles faster, improves the preparation efficiency, and shortens the preparation time. Specifically, as an implementation scheme, the flow disturbance body 25 is a block that is inclined and arranged at intervals, and the flow disturbance hole 26 on the flow disturbance body 25 is a variable diameter hole. In this implementation scheme, the flow disturbance body 25 is staggered to facilitate the welding of the flow disturbance body 25. As another implementation scheme, the flow disturbance body 25 is a plurality of sheets arranged at intervals in the height direction. In this implementation scheme, the sheets are first welded on a plate, and then the plate is directly welded to the inner wall of the mixing barrel 2. As a fixing scheme for the mixing barrel 2, the outer side of the mixing barrel 2 is provided with a fixed wing plate 22, and the fixed wing plate 22 is fixed to the bracket containing the system by bolts.

On the one hand, the gas is directly introduced from the lower end of the water so that the gas directly enters the water. On the other hand, this embodiment installs multiple air outlet ends 27 in the mixing barrel 2, and the lower end of the air outlet end 27 has a threaded end 29. As a connection scheme for the air outlet end 27, the mixing barrel 2 of this embodiment has a threaded joint, specifically the upper end surface of the lower sealing cover 24, and the air outlet end 27 is threadedly connected to the threaded joint.

The air outlet end 27 has an air outlet hole 28, and the air outlet hole 28 is a variable diameter hole. The aperture on the inner side of the air outlet end 27 is larger than the aperture on the outer side of the air outlet end 27, so that bubbles are formed in advance when the air flow enters the water. This structure also reduces the amount of liquid in the mixing barrel 2 that enters the distributed air pipe 75 along the air outlet hole 28, and a small portion of the liquid that enters the distributed air pipe 75 enters the mixing barrel 2 again with the air flow.

[0061] As the structure of the finished product storage tank 5, specifically, the pressure inside the mixing cylinder 2 is greater than the pressure inside the finished product storage tank 5, so that the gas-liquid mixed liquid in the mixing cylinder 2 can enter the finished product storage tank 5. The finished product storage tank 5 of this embodiment has multiple tank bodies 51 to ensure that the prepared gas-liquid fusion liquid has a place to be stored after entering the finished product storage tank 5, and the mixing cylinder 2 can continuously prepare the gas-liquid fusion liquid and store it in the finished product storage tank 5.

In this embodiment, the volume of the liquid storage chamber 57 is changed to adapt to the volume of the gas-liquid fusion liquid entering the liquid storage chamber 57.

A distributed air pipe 75 is installed on the solenoid valve 74, and the distributed air pipe 75 has multiple joints, which are connected to the lower end of the mixing cylinder 2. When installing, the distributed air pipe 75 is first installed on the lower sealing cover 24 of the mixing cylinder 2, and then the lower sealing cover 24 is installed on the cylinder body 21 of the mixing cylinder 2. As a matching pipeline with the finished product storage tank 5, the air intake pipe of this embodiment has an air intake branch pipe 71, and the air intake branch pipe 71 is installed with a front-end gas control valve 78 and a rear-end gas control valve 79. The front-end gas control valve 78 is used to control the opening and closing of the intake branch pipe 71, and the rear-end gas control valve 79 is used to control the gas entering the finished product storage tank 5. The intake branch pipe 71 is connected to the gas storage chamber 58. A return pipe 76 is installed on the intake branch pipe 71.

In this embodiment, multiple finished product storage tanks 5 are arranged. The front end liquid outlet control valve 82 controls the discharge of the gas-liquid fusion liquid in the mixing barrel 2, and the rear end liquid outlet control valve 83 controls the gas-liquid fusion liquid to enter the finished product storage tank 5.
