Totally-enclosed gas atomizing powder making device for preventing high-melting-point substance from being blocked

Abstract

The invention discloses a totally-enclosed gas atomizing powder making device for preventing a high-melting-point substance from being blocked. The device comprises a heat-preserving crucible, an atomizer, an atomizing tower, a telescopic plastic pipe A, a telescopic plastic pipe B and the like, wherein the atomizer is arranged in the telescopic plastic pipe A; the telescopic plastic pipe A is hermetically connected with the heat-preserving crucible and the upper surface of a nozzle of the atomizer respectively; and the atomizing tower is hermetically connected with the lower surface of the nozzle through the telescopic plastic pipe B, so that a totally-enclosed system structure is formed, and the formation of a high-melting-point substance on the atomizer and caused blockage of the atomizer can be prevented. A heating body is arranged in a gap between a honeycomb duct of the atomizer and a metal jacket, so that nozzle blockage caused by a metal or an alloy can be solved by electrifying. When the atomizer is blocked, the problem of blockage can be solved by replacing a ceramic circular ring. The totally-enclosed gas atomizing powder making device for preventing the high-melting-point substance from being blocked disclosed has the advantages of simple structure, convenience for installing, effective prevention and solving of blockage, improvement on the powder quality, and the like.
