APPARATUS FOR WASHING THE METAL POWDER

摘要

A device for cleaning metal powder is provided to effectively separate and remove impurities adhered to the metal powder while pulverizing metal powder by injection of high pressure water and high pressure air. A device(100) for cleaning metal powder comprises: a cleaning vessel(110) for cleaning metal powder filled therein; a high pressure water spray nozzle(120) for spraying cleaning water in a high pressure state in the downward direction from an upper central part within the cleaning vessel to simultaneously hit the metal powder and separate and remove impurities adhered to the metal powder by the reciprocal interference generated while the metal powder flows; and at least two high pressure air ejection nozzles(130) which are circumferentially installed on a lower outer part of the cleaning vessel and eject air in a high pressure state in the downward inclined direction from the outside to a bottom central part of the cleaning vessel to simultaneously hit the metal powder and separate and remove the impurities adhered to the metal powder by the reciprocal interference generated while the metal powder flows.
