[0016] The following is a further detailed description through specific implementation methods:

[0017] like Figure 1 As shown:

[0018] A powder mixing device comprises a mixing tank 11, a feeding port 12 is provided at the top of the mixing tank 11 for feeding materials, a discharge pipe 17 at the bottom is provided for discharging the powder in the mixing tank 11, a valve is provided at the discharge pipe 17, and the valve is provided for controlling the on and off of the discharge pipe 17;

[0019] The device further comprises a driving module, a stirring assembly and a mixing module. The driving module is mounted on the top of the stirring tank 11. The driving module is connected to the stirring assembly and the stirring assembly is located inside the stirring tank 11. The driving module is used to drive the stirring assembly to operate and stir and mix the powder in the stirring tank 11. The mixing module is arranged at the inner bottom of the stirring tank 11 and is used to mix the powder while preventing the powder from accumulating at the bottom of the stirring tank 11.

[0020] The mixing module includes a sintering bucket 31 and a support frame 32. The sintering bucket 31 is fixedly installed on the inner bottom of the stirring tank 11 through the support frame 32. The sintering bucket 31 is made of a sintering plate, so that fine small holes are formed at the sintering bucket 31. The edge of the sintering bucket 31 is sealed and connected to the inner side wall of the stirring tank 11. The space between the sintering bucket 31 and the inner bottom wall of the stirring tank 11 forms a high-pressure gas chamber 15. The high-pressure air input into the high-pressure gas chamber 15 can enter the upper space of the sintering bucket 31 through the small holes of the sintering bucket 31, and form micro bubbles at the powder filled in the sintering bucket 31, so that the powder tumbles and then mixes the powder.

[0021] The stirring assembly includes a plurality of first stirring modules and a second stirring module. The first stirring module is located on the upper side of the second stirring module. The first stirring module includes a mounting sleeve 21 and a plurality of stirring paddles 22. The outer side of the mounting sleeve 21 is evenly mounted with a plurality of stirring paddles 22. The mounting sleeve 21 is sleeved on the rotating shaft 14 of the driving module, so that when the rotating shaft 14 rotates, the mounting sleeve 21 can be driven to drive each stirring paddle 22 to rotate, so that the powder in the stirring tank 11 can be stirred.

[0022] The second stirring module includes a plurality of stirring rods 23 and a plurality of stirring springs 24. One end of the stirring rod 23 is fixedly connected to the rotating shaft 14 of the driving module. The stirring rod 23 is adapted to the inner wall of the sintering bucket 31, that is, the stirring rod 23 is close to the inner wall of the sintering bucket 31. There is a small gap between the stirring rod 23 and the inner wall of the sintering bucket 31 to avoid contact between the stirring rod 23 and the sintering bucket 31 and affect the movement of the conceptual stock stirring rod 23. A plurality of stirring springs 24 are evenly installed on the top side of the stirring rod 23. The stirring spring 24 can enhance the stirring and mixing effect of the stirring rod 23.

[0023] An air inlet connector 16 is installed on the outer wall of the mixing tank 11 . The air inlet connector 16 is communicated with the high-pressure gas chamber 15 . The air inlet connector 16 is connected to an external high-pressure gas source for inputting high-pressure air into the high-pressure gas chamber 15 .

[0024] The driving module includes a driving motor 13, a reducer and a rotating shaft 14. The driving motor 13 is connected to the reducer. The reducer is installed on the top of the stirring tank 11. The reducer is connected to the rotating shaft 14. The driving motor 13 can drive the rotating shaft 14 to rotate through the reducer, and the rotating shaft 14 can drive the stirring component to operate.

[0025] The specific implementation process is as follows:

[0026] When the powder mixing device is used, each powder is fed into the stirring tank 11 through the feed port 12, and then the driving motor 13 is started and high-pressure air is delivered to the high-pressure air bin 15 through the air inlet joint 16. The driving motor 13 drives the rotating shaft 14 to rotate through the reducer, and the rotating shaft 14 drives the mounting sleeve 21 and the stirring paddle 22 on the mounting sleeve 21 to rotate, and the stirring paddle 22 can stir and mix the powder in the stirring tank 11. At the same time, the rotating shaft 14 drives each stirring rod 23 and the stirring spring 24 on the stirring rod 23 to move, and the stirring rod 23 can mix and stir the powder in the stirring tank 11; the high-pressure air in the high-pressure air bin 15 enters the powder on the sintering bucket 31 through the fine holes on the sintering bucket 31, and forms microbubbles in the powder on the sintering bucket 31, and the microbubbles can form an air film on the surface of the sintering bucket 31, and the microbubbles can tumble the powder, and then mix and stir the powder.

[0027] The powder mixing device stores powder in a stirring tank 11, and inputs high-pressure air into a high-pressure air bin 15 through an air inlet joint 16, so that dense small bubbles emerge from a sintering bucket 31 made of a sintered plate, and an air film is formed on the surface of the sintering bucket 31 to prevent powder accumulation. The small bubbles drift into the material distribution to cause the powder to tumble, thereby stirring and mixing the powder. At the same time, the first stirring module and the second stirring module of the stirring assembly synchronously stir the powder, so that the powder can be effectively stirred and mixed, and the possibility of accumulation and deterioration of the powder in the stirring tank 11 is effectively reduced.
