本发明属于粉末冶金技术领域，涉及一种真空热动态金属粉末除气装置。真空热动态金属粉末除气装置，包括待除气粉末储存罐、包套、真空球阀、真空计、真空机组、三通管道、环形加热器、超声发射器、粉末输送管道以及除气管道；粉末输送管道为螺旋形管道，螺旋形管道的上端与三通管道连接，螺旋形管道的下端与第二真空球阀连接，可使粉末在管道螺旋区域中缓慢下降。采用该结构，真空热动态除气过程在粉末输送管道螺旋区域内完成，粉末在管道螺旋区域中缓慢下降，在高温高频振动下粉末充分与真空环境接触，脱解表面气体吸附，能够实现良好而稳定的除气处理；除气过程中不需要操作人员值守操作，可以实现连续的除气处理；不需对包套进行整体加热保温。

The invention belongs to the technical field of powder metallurgy, and relates to a vacuum thermal dynamic metal powder degassing device. Vacuum thermal dynamic metal powder degassing device, including the storage tank, sleeve, vacuum ball valve, vacuum meter, vacuum unit, three-way pipe, annular heater, ultrasonic transmitter, powder conveying pipeline and degassing pipeline; powder conveying pipeline is spiral pipe, the upper end of spiral pipe is connected with the three-way pipe, and the lower end of spiral pipe is connected with the second vacuum ball valve The connection allows the powder to slowly drop in the pipe helix area. With this structure, the vacuum thermal dynamic degassing process is completed in the spiral area of powder conveying pipeline, the powder slowly drops in the spiral area of the pipeline, and the powder is fully contacted with the vacuum environment under high temperature and high frequency vibration, and the surface gas adsorption is desorbed, so that a good and stable degassing treatment can be achieved; in the degassing process, no operator is required to operate on duty, and the continuous degassing place can be realized No need to heat and heat the sleeve as a whole.
