POWDER RECOVERY DEVICE IN GLOVE BOX

摘要

PROBLEM TO BE SOLVED: To provide a powder recovery device which efficiently recovers powder in a glove box (GB). SOLUTION: The powder recovery device in the GB includes a compressed air supply plug 4 exposed to inside of the GB chamber 11 for supplying compressed air for work, and an air exhaust device 3 for maintaining the pressure in the GB chamber lower than external air. The powder recovery device 5 includes an ejector gun 52 for generating a negative pressure using the compressed air supplied by being connected to the compressed air supply plug, a powder suction pipe 53 for sucking in the powder in the GB chamber by generating powder sucking air current by the negative pressure generated by the ejector gun, and a cyclone separator 54 for separating the powder by centrifugation from the powder sucking air current by being placed in between the ejector gun and the powder suction pipe. The cyclone separator includes a centrifuge body 541 for separating the powder by swirling the powder sucking air current and a powder recovery container 542 for housing the separated powder by being detachably attached to the centrifuge body.
