[0020] See also Figure 1 and Figure 2 The first support frame 3 is detachably connected to the mixing tank 1 by bolts, and the second support frame 4 is detachably connected to the mixing tank 1 by bolts. This arrangement can provide fixed support for the high-pressure gas tank 5 above through the first support frame 3, and provide fixed support for the vacuum pump 6 and the control box 7 above through the second support frame 4.

[0021] See also Figure 3 The stirring head 14 includes a hard rod 1401, and the hard rod 1401 is wrapped with a rubber sleeve 1402. This arrangement can avoid the danger of sparks caused by direct friction and stirring between the stirring head 14 and zinc powder through the rubber sleeve 1402, thereby improving the safety of the mixed material.

[0022] See also Figure 2 A breathable isolation membrane 16 is provided at the end of the pipe of the vacuum pump 6 disposed inside the mixing tank 1, so that the zinc powder material inside the mixing tank 1 can be prevented from being sucked out.

[0023] See also Figure 1 and Figure 2 The high-pressure gas tank 5 is filled with high-pressure nitrogen. Nitrogen has low cost, good protection performance, and is easy to obtain. It is a relatively cheap and effective protective gas.

[0025] Working principle: When using this device, first inject the zinc powder material to be mixed into the mixing tank 1 through the feed valve 8, then close the feed valve 8, and input the working instruction through the control box 7. The control box 7 controls the vacuum pump 6 to start, and the vacuum pump 6 extracts the air in the mixing tank 1 to form a vacuum state in the mixing tank 1. Then the control box 7 controls the motor 11 to start, and the motor 11 drives the stirring head 14 to rotate through the transmission shaft 13, and the stirring head 14 mixes and stirs the zinc powder material in the mixing tank 1. In this process, the high-pressure gas in the high-pressure gas tank 5 is depressurized and then sprayed out through the gas diverter 15. The high-speed airflow accelerates the mixing efficiency of the zinc powder. At the same time, the protective gas in the mixing tank 1 can also provide a certain period of protection when the zinc powder is discharged through the discharge pipe 12, thereby reducing the oxidation of the zinc powder by oxygen in the air and improving the mixing quality of the zinc powder.
