SEPARATOR APPARATUS AND SHOT PROCESSING APPARATUS

WIPO Patent Application WO/2017/212898

A1

A separator apparatus according to the present invention has: a suction means for suctioning air; and an air-power separation mechanism for separating a projection material from a mixture by air power. The air-power separation mechanism is provided with: an air flow-passage that generates an air flow by the suction force of the suction means and that horizontally extends from an inlet to an outlet; a mixture supply port that is formed above the midstream side of the air flow-passage; and a separation unit that separates an object that is carried through an air flow and crosses over a prescribed reference height position and an object that does not cross over the reference height position and falls, by applying an air flow to a mixture including the projection material and granular foreign matter by dropping the mixture in a free fall from the mixture supply port to the air flow-passage. The air flow-passage is provided with an air velocity stabilization unit that is formed upstream of the mixture supply port and in which the area of the air-passage cross-section orthogonal to the circulation direction of the air flow is constant. By having this configuration, the air velocity stabilization unit rectifies the air flow and makes uniform the velocity distribution within the flow-passage cross-section of air supplied downstream.
