Abstract
An airless centrifugal blast device in the form of a one piece, two-bladed wheel mounted for rotational movement about either a horizontally or vertically disposed axis and means for off center gravitational feed of particulate media to the inner end portions of the blades with the particulate media feed tube means tapering in cross section to the discharge opening and extension of the discharge opening in the direction of rotation of the wheel.
Claims20
A device for airless blast with particulate media comprising wheel blades mounted for rotational movement in a vertically disposed plane, means offset laterally from the plane of rotation of the blades for feeding particulate material from a feeding opening in crosswise alignment with the inner end portions of the blades to the inner end portions of the wheel blades for engagement by the blades during rotational movement of the wheel at high speed whereby the engaged particulate media is projected from the ends of the blades comprising a vertically disposed tubular member having vertically disposed side walls and an inlet opening at the top and an opening in the vertically disposed side wall below the inlet and a horizontally disposed hollow body having an open end portion extending from and in registry with the opening in the side wall of the tubular member and a feed opening in an end portion facing the wheel blades and laterally offset from the lateral edges thereof for flowing particulate media from the inlet, through the tubular member and hollow body onto the inner end portions of the blades.
A device for airless blast with particulate media comprising a housing having an open side, a two-bladed wheel mounted within the housing for rotational movement about the central horizontally disposed axis, means for imparting rotational movement to the wheel, a means offset laterally from the plane of rotation of the blades for feeding particulate media from a feed opening in crosswise alignment with the end portions of the blades onto the inner end portion of the blades but offset laterally from the central axis, comprising a vertically disposed tubular member having vertically disposed side walls and an inlet opening at the top and an opening in the side wall below the inlet, a horizontally disposed hollow body having an open end portion in registry with the opening in the side wall of the tubular member and a feed opening in an end portion facing the wheel blades and laterally offset from the lateral edges thereof for flowing particulate media from the inlet through the tubular member and hollow body onto the inner end portion of the blades whereby the engaged particulate media is displaced centrifugally over the face of the blades and projected from the blades through the open side.
