Totally-enclosed gas-atomizing powder preparation device for solving blockage of nozzle and liquid guiding pipe caused by high-melting-point material

Abstract

The invention discloses a totally-enclosed gas-atomizing powder preparation device for solving blockage of a nozzle and a liquid guiding pipe caused by a high-melting-point material. The totally-enclosed gas-atomizing powder preparation device consists of a heat-preserving crucible, an atomizer, an atomizing tower, a retractable plastic pipe A, a retractable plastic pipe B, a vacuum pump and the like, wherein the atomizer is installed in the retractable plastic pipe A, the retractable plastic pipe A is hermetically connected with the heat-preserving crucible and the upper surface of a nozzle of the atomizer, and the retractable plastic pipe B is hermetically connected with the atomizing tower and the lower surface of the nozzle, so that a totally-enclosed system structure, which can prevent the high-melting-point material from being generated on the atomizer, is formed; a gap is maintained between the liquid guiding pipe and a metal outer sleeve and used for installing a heating element A, and a heating element B is installed in a gap between the air outlet pipes of two Laval structures of the nozzle, so that the heating element A and the heating element B can be used for solving the problem of blockage caused by the high-melting-point material when being simultaneously powered on. The totally-enclosed gas-atomizing powder preparation device for solving the blockage of the nozzle and the liquid guiding pipe caused by the high-melting-point material, provided by the invention, has the advantages that the structure is simple, the installation is convenient, the blocking problem can be effectively avoided and solved, the powder quality can be improved and the like.
