The two ends of the mixing auxiliary shaft 5 extend through and out of the two sides of the mixing main shaft 3, respectively. The included angle between the axis of the mixing auxiliary shaft 5 and the axis of the mixing main shaft 3 is set to 40°.

[0023] By setting the motor 4 to drive the stirring main shaft 3 to rotate, the rotation of the stirring main shaft 3 can drive the stirring auxiliary shaft 5 to rotate around the stirring main shaft 3, and the angle between the axis of the stirring auxiliary shaft 5 and the axis of the stirring main shaft 3 is set to 40°, so that the stirring auxiliary shaft 5 and the stirring main shaft 3 can stir the sodium hydride in different directions, making the sodium hydride stirring reaction in the stirring tank 1 more complete.

[0024] A C-shaped stirring rod 6 is fixedly installed at the lower end of the stirring sub-shaft 5. Multiple C-shaped stirring rods 6 are arranged in a circular array around the arc surface of the stirring sub-shaft 5. A self-priming fan blade 7 is fixedly installed on the lower arc surface of the stirring main shaft 3.

[0025] By rotating the main stirring shaft 3 and the auxiliary stirring shaft 5 simultaneously, the auxiliary stirring shaft 5 itself can also rotate, causing the C-shaped stirring rod 6 at the bottom of the auxiliary stirring shaft 5 to stir the sodium hydride liquid. The self-priming fan blades 7 fixed on the main stirring shaft 3 draw hydrogen gas from the stirring tank 1 into the sodium hydride liquid for stirring and reaction.

[0026] To enable the stirring sub-shaft 5 to rotate, a fixing ring 8 is fixedly installed on the inner top surface of the stirring tank 1. A fixing helical gear 9 is fixedly installed on the outer arc surface of the fixing ring 8. A fixing plate 10 is fixedly installed on the arc surface of the stirring main shaft 3.

[0027] By setting the fixed plate 10, the rotation of the stirring main shaft 3 driving the stirring secondary shaft 5 is made more stable and safe. The rotating helical gear 11 and the fixed helical gear 9 mesh, so that the rotation of the stirring secondary shaft 5 causes the rotating helical gear 11 to rotate around the fixed helical gear 9, so that the stirring secondary shaft 5 can rotate on its own while rotating, and the U-shaped stirring rod 6 stirs the sodium hydride liquid.

[0028] An air inlet 12 is provided at the upper part of the mixing tank 1. An air pump 13 is fixedly installed at the upper part of the mixing tank 1. An air supply pipe 14 is fixedly installed at the output end of the air pump 13. One end of the air supply pipe 14 is fixedly connected to the upper part of the air inlet 12.

The feed inlet 15 is set up to add the sodium hydride liquid that needs to be stirred into the mixing tank 1, and the discharge valve 16 is set up to discharge the liquid after the stirring is completed.

[0030] Working principle: First, the sodium hydride liquid to be stirred and reacted is poured into the stirring tank 1 through the feed inlet 15. Then, the feed inlet 15 is closed to prevent gas leakage. Next, the motor 4 is started to drive the stirring main shaft 3 to rotate. The rotation of the stirring main shaft 3 drives the stirring auxiliary shaft 5 to rotate around the stirring main shaft 3. The angle between the axis of the stirring auxiliary shaft 5 and the axis of the stirring main shaft 3 is set to 40°, so that the stirring auxiliary shaft 5 and the stirring main shaft 3 stir the sodium hydride in different directions, making the sodium hydride stirring and reaction in the stirring tank 1 more complete. Then, the air pump 13 is started to open the gas pump. Hydrogen gas is delivered into the mixing tank 1 through the gas supply pipe 14 and the gas inlet 12. The self-priming fan blades 7 fixed on the mixing main shaft 3 draw the hydrogen gas in the mixing tank 1 into the sodium hydride liquid for stirring and reaction. The rotation of the mixing sub-shaft 5 causes the rotating helical gear 11 to rotate around the fixed helical gear 9, so that the mixing sub-shaft 5 can rotate on its own axis while rotating. The C-shaped stirring rod 6 at the lower end of the mixing sub-shaft 5 stirs the sodium hydride liquid at an inclined angle, so that the stirring and reaction of the sodium hydride liquid is more complete. Finally, the fully stirred and reacted liquid is discharged through the discharge valve 16.
