The present invention relates to a shot blast device for processing an inner wall of an object using a vertical impeller boom. The present invention is characterized by comprising: a room unit having an inner containing portion and one side door; a transferring unit for processing an object which is installed on the door side of the room unit; a shot ball projecting unit installed on the upper part of the room unit; an elevating unit for the projecting unit; a feeding unit for providing a shot ball into the projecting unit, wherein projecting unit additionally comprises: a shaft which is rotated by a operating means; a housing which surrounds the outer circumference of the shaft and has a shot ball flowing path between the shaft and itself; an impeller which contains multiple heat blades projecting, to the wall of a space unit of the object to be processed, a wheel coupled with the lower parts of the shaft and shot balls radially arranged in the wheel so as to pass the flowing path and fall. According to this constitution, the impeller of the projecting unit performs an elevating motion along with the object to be processed so as to project the shot balls toward the inner wall of the space unit of the object to be processed, such that the present invention has effects of capable of quickly and safely removing foreign materials attached in the inner wall of the space unit. |
