DEVICE FOR SEPARATING BLASTING DUST FROM BLASTING AGENT

摘要

PURPOSE: To simplify the structure of a dust separating device by connecting an air guide means in a negative pressure generator to a compressor for dispensing with a large conduit for a fan device and between a dust collecting device and the fan device. CONSTITUTION: Blasting dust 15 separated from a blasting agent 13 through a separating space 16 is absorbed from the inside of the space 16 into the dust collecting device by a negative pressure generated in the dust collecting device through a negative pressure generator 20. At the same time, the blasting agent 13 is supplied to a recirculating device for recycling. In this case, an air guide means 32 in the negative pressure generator 20 is connected to the compressor, and an air sent from the compressor is supplied through a blasting dust leading port 30 toward a blasting dust collecting container.
