The invention relates to the technical field of metallurgical powder making, and discloses a material collecting chamber for a gas atomization metal powder device. The material collecting chamber comprises an atomization chamber body, a melting tank is fixedly mounted in the top end of the atomization chamber body, a recovery pipe is fixedly mounted on one side of the atomization chamber body, and a recovery chamber body is fixedly mounted at one end of the recovery pipe. According to the material collecting chamber, powder particles are vertically intercepted by gas flowing out of exhaust grooves by utilizing the exhaust grooves, powder flying caused by the fact that the powder particles directly impact the inner wall of the material collecting chamber can be avoided, the circulation directions of the gas in a gas recovery pipe and a gas supply pipe are opposite by utilizing the design that the gas recovery pipe and the gas supply pipe are staggered, temperature difference exists, through cold and heat conduction, the recovered gas is converted into low-temperature gas, the powder particles in the material collecting chamber are cooled, it is guaranteed that the powder particles are not liable to oxidation, by means of a collecting winding roller, when the powder particles are guided to the surface by the recovery gas flow, the gas is separated from the powder particles, and therefore the effect of collecting the powder particles is achieved.
Description
technical field [0001] The invention relates to the technical field of metallurgical powder making, in particular to a collection chamber for a gas atomized metal powder device. Background technique [0002] The gas atomization method is to directly crush the liquid metal or alloy to form fine droplets with a diameter less than (150) μm, which will become metal powder after condensation. This method can be used to prepare various metal powders and alloy powders. It is a simple and convenient method. , An economical powder production method, the gas atomized metal powder device is generally composed of a vacuum induction melter, a gas source, a nozzle group, an atomization chamber, and a collection chamber. It is melted into a liquid state, and the high-pressure gas is transported to the nozzle group through the gas source, and the metal liquid flow is crushed by the high-pressure gas, so that it is gradually dispersed into droplet particles, and the droplet particles will ev...
