[0024] Working principle: This embodiment provides an atomization device for producing metal alloy powder. When in use, first put the solid metal parts into the beaker 701, then fix the lid to the top wall of the combustion tank 2 by bolts, and then make the heating wire ring 702 work through the external circuit mechanism. The solid metal parts melt into liquid metal during the heating process, and the liquid flows from the upper groove of the filter tube 703 and into the atomization tank 3 through the liquid metal nozzle 704. In this process, the gas pipe 601 is connected to the external storage tank for storing inert gas, and the inert gas is passed through the gas pipe 601 through the external switch. The liquid metal is sprayed out from the atomizing tank 3 and dispersed. After being dispersed, the liquid metal is quickly cooled to form a granular powder and flows into the screening tank 4 through the through hole through the gas. In this process, the air pressure in the screening tank 4 and the atomizing tank 3 is too high, which will cause the metal powder in the atomizing tank 3 to stop flowing and accumulate in the dead corner of the atomizing tank 3. Part of the inert gas in the atomizing tank 3 can be discharged through the air outlet 603 to reduce the air pressure therein. After the inert gas and the metal powder enter the screening tank 4, the fast-flowing gas can change the gas flow direction through the guide plate 504, and then The air can be gathered through the air guide piece 504a and flowed in the direction of the transmission blade 505, so that the transmission rod 503 rotates.

When the toggle rod 506 rotates, the roller 509 also rolls on the slideway 502, and the roller 509 can be lifted upward after passing through the protrusion 502a, so that the vibration rod 508 is tilted through the hinge, so that the vibration rod 508 on one end of the vibration rod 508 is The movable hammer 510 moves downward and hits the screen mesh in the vibrating screen frame 501, causing the screen mesh to vibrate as a whole, thereby vibrating and screening the metal powder. During the downward hitting of the movable hammer 510, the spring 2 511 can make the movable hammer 510 repeatedly hit the screen mesh and slowly stop, waiting for the next strike. At the same time, the screen mesh in the vibrating screen frame 501 can drive the vibrating screen frame 501 to shake while vibrating, and then the spring 1 501a-1 and the limit rod 501a can make the vibrating screen frame 501 shake repeatedly. In this process, the phenomenon of shaking the entire device caused by the vibration motor can be avoided.
