[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a hydrogen-helium-nitrogen-oxygen diving mixed gas mixing device, comprising a mixing tank 1, an upper end of the mixing tank 1 is fixedly connected to an air inlet 11, and an exhaust port 12 is opened at the middle end of the lower side of the mixing tank 1, the upper end of the air inlet 11 is fixedly connected to a booster component, and the upper middle end of the mixing tank 1 is fixedly connected to a rotating component, the outer side of the lower end of the rotating component is sleeved with a partition component, and the outer side of the upper end of the partition component is fixedly connected to a guide component, and the lower side of the exhaust port 12 is fixedly connected to an exhaust component. When mixing hydrogen, helium, nitrogen and oxygen gases, the hydrogen, helium, nitrogen and oxygen gases are first injected into the mixing tank 1 through the booster component using the air inlet 11, and then enter the partition component with the assistance of the guide component. The inside of the component is then started, and the rotating component is used to stir the multiple gases while moving them downward. After the multiple gases are mixed and moved downward, they are assisted by the partition component and the change of the airflow, so that they flow from the lower end of the mixing tank 1 to the outside of the partition component under the guidance of the guide component, and then rise from the outside of the partition component to the upper end of the mixing tank 1. After multiple cycles of stirring, the mixture is evenly mixed, and then the exhaust component can be opened to discharge the mixed gas through the exhaust component. When the mixing device stirs and mixes the hydrogen, helium, nitrogen and oxygen gases, it can be made to rotate and mix in the mixing tank 1 while also circulating and moving up and down, and the change of the flow rate of the airflow can be used to improve the mixing efficiency and mixing uniformity of the gases.

[0020] like Figure 1 and Figure 2As shown, the boosting component includes a gas booster 2 fixedly connected to the upper end of the air inlet 11, and an air inlet pipe 21 is fixedly connected to the upper end of the gas booster 2. The gas is injected into the gas booster 2 through the air inlet pipe 21, and then the gas is pressurized by the gas booster 2 and then injected into the mixing tank 1 through the air inlet 11, thereby increasing the flow rate of the gas during injection for subsequent stirring and mixing.

[0021] like Figure 2 As shown, the rotating assembly includes a motor 3 fixedly connected to the middle end of the upper side of the mixing tank 1, and the output shaft of the motor 3 is fixedly connected to the stirring rod 31, the lower end of the stirring rod 31 is inserted into the mixing tank 1, and the motor 3 is started, and the stirring rod 31 is driven to rotate by the output shaft of the motor 3, so that the mixed gas is stirred and mixed by the rotation of the stirring rod 31, and the mixed gas is pressed downward by the rotation of the stirring rod 31.

[0022] like Figure 2 and Figure 3 As shown, the partition assembly includes an isolation cover 4 sleeved on the outer side of the lower end of the stirring rod 31, and a fixed plate 41 is fixedly connected to the lower side of the isolation cover 4. The lower end of the fixed plate 41 is fixedly connected to the mixing tank 1. The separation of the isolation cover 4 can separate the mixed gas, allowing it to circulate for subsequent mixing.

[0023] like Figure 2 As shown, the guide assembly includes a first guide cover 5 fixedly connected to the outer side of the upper end of the isolation cover 4, and a second guide cover 51 is provided on the upper end of the isolation cover 4. The upper end of the second guide cover 51 is fixedly connected to the mixing tank 1. While guiding the mixed gas through the first guide cover 5, the mixed gas can also be compressed, thereby increasing the flow rate of the mixed gas.

[0024] like Figure 2 As shown, the exhaust assembly includes an exhaust pipe 6 fixedly connected to the lower side of the exhaust port 12, and a spiral blade 61 fixedly connected to the inner side of the exhaust pipe 6, and the mixed gas is discharged through the exhaust pipe 6. At the same time, when the mixed gas is discharged through the exhaust pipe 6, it is guided by the spiral blade 61 to rotate, thereby making the mixed gas.

[0025] Working principle: When mixing hydrogen, helium, nitrogen and oxygen gases, first inject the hydrogen, helium, nitrogen and oxygen gases into the gas booster 2 through the air inlet pipe 21, then pressurize the hydrogen, helium, nitrogen and oxygen gases through the gas booster 2 and then inject them into the mixing tank 1 through the air inlet 11. After the pressurized hydrogen, helium, nitrogen and oxygen enter the mixing tank 1, they are guided by the second guide cover 51 to enter the isolation cover 4, and then the motor 3 is started. After the motor 3 is started, the output shaft drives the stirring rod 31 to rotate, and the rotation of the stirring rod 31 is used to stir the hydrogen, helium, nitrogen and oxygen gases while making them flow downward. After the hydrogen, helium, nitrogen and oxygen mixed gas flows downward, it comes out from the upper end of the mixing tank 1 Negative pressure is present, at this time the stirring rod 31 continues to rotate to make the mixed gas flow to the outside of the isolation cover 4, and then the mixed gas is guided by the first guide cover 5 and the subsequent mixed gas is squeezed. The mixed gas at the lower end of the mixing tank 1 rises outside the isolation cover 4. At this time, due to the inclination of the first guide cover 5, the mixed gas is squeezed to increase its compression flow rate, and then it is guided by the second guide cover 51 to enter the isolation cover 4 and continue to be stirred and pressed down by the stirring rod 31. After multiple cycles of stirring, it is mixed evenly. After the mixing is completed, the exhaust pipe 6 can be opened, and then the mixed gas can be rotated and discharged from the exhaust pipe 6 under the guidance of the spiral blade 61.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
