The ratio of the mixed metal powder can be accurately controlled by controlling the gas flow in the cooling pipe 5 and the power of the high-temperature evaporation furnace 1. The metal powder is cooled in the buffer cooling tank 2 and mixed by using the gas flowing at a high speed, thereby improving the mixing effect of the metal powder.
The rotary shaft 14 in the buffer cooling tank 2 is rotatably provided with the vertical rotary shaft 14, the rotary shaft 14 is sequentially provided with the linkage vane wheel 15 and the vane wheel 16 from top to bottom, the linkage vane wheel 15 and the vane wheel 16 are respectively and fixedly connected with the rotary shaft 14, the linkage vane wheel 15 is fixedly connected with a plurality of linkage vanes 17 which are arranged in a circle array, the vane wheel 16 is fixedly connected with a plurality of vanes 18 which are arranged in a circle array, the bottom of the buffer cooling tank 2 is provided with a discharge hole 19, the connecting pipe 6 is connected with the discharge hole 19, a plurality of air inlets 20 are arranged around the buffer cooling tank 2, the air inlets 20 and the linkage vane wheel 15 are positioned at the same height, the air inlets 20 are in one-to-one correspondence with the cooling pipes 5, the cooling pipes 5 are respectively connected with the corresponding air inlets 20, and the air entering the buffer cooling tank 2 from the air inlets 20 acts on the linkage vane 17 to drive the linkage vane wheel 15, the rotary shaft 14 and the vane wheel 16 to rotate positively, and the fan wheel 16 rotates positively and then negative pressure is formed above the vane wheel 16. The air entering the buffer cooling tank 2 from the air inlet 20 acts on the linkage blade 17 to drive the linkage blade wheel 15 to rotate. The rotation of the linkage vane wheel 15 drives the rotation shaft 14 to rotate, and then drives the fan impeller 16 to rotate. The metal powder entering the buffer cooling tank 2 from different air inlets 20 is uniformly mixed by utilizing the rotation of the linkage vane wheel 15 and the rotation of the vane wheel 16.

The elastically connected linkage blade 17 can store the force through the spring 21 after being stressed, and the force is released in the rotating process, and the stored linkage blade wheel 15 rotates. When the wind force formed by the gas is small, the linkage blade 17 can be pushed to move, so that the problem that strong wind force is required to blow the linkage blade wheel 15 due to the problem of stress angle when the linkage blade 17 just stops at the air inlet 20 is avoided.
The cooling air pipe 13 is provided with a heat exchanger 22, and the cooling air pipe 13 is cooled by the heat exchanger 22. The gas in the cooling air pipe 13 is cooled to a certain temperature and then enters the cooling pipe 5, so that the metal is cooled and solidified to form granular metal powder in the process of conveying gaseous metal.
The muffler 12 is provided with a heater 23. The heater 23 is used for preheating the gas entering the high-temperature evaporation furnace 1, so that the temperature in the high-temperature evaporation furnace 1 is prevented from being influenced by the excessively low transition of the gas temperature, and the solidification of gaseous metal at the joint of the gas return pipe 12 and the high-temperature evaporation furnace 1 is avoided.
