Nanometer silicon powder plasma preparation system

Abstract

The utility model discloses a nano silicon powder plasma preparation system, relates to the field of nano silicon powder preparation, and solves the problems of low preparation efficiency and low practicability due to the fact that an existing device needs to use open fire to heat up, and adopts the following scheme that the nano silicon powder plasma preparation system comprises a spheroidizing furnace body, a plasma torch system and a feeding system are fixedly mounted at the top of the spheroidizing furnace body, and a receiving system is fixedly mounted at the bottom of the spheroidizing furnace body; the plasma torch system is composed of three torches inclining inwards in the same direction. A main body of the feeding system is a spiral feeder, and the tail end of the spiral feeder is fixedly connected to a trough in the top of the spheroidizing furnace body; a main body of the material receiving system is a ceramic filter; according to the nano silicon powder plasma preparation system, through the arrangement of the device, electric energy can be directly converted into fluid heat energy by utilizing a plasma torch system, convection heat exchange is carried out through plasma high-temperature flame flow and high-melting-point particles, the surfaces of the particles are melted, and the technology that the particles have regular spheres is achieved.
