Machine for treatment of large vertical surfaces

Abstract

Abstract A MACHINE AND METHOD FOR TREATMENT OF VERTICALLY DISPOSED SURFACES OF LARGE DIMENSION WITH DRY PARTICULATE MATERIAL COMPRISING MEANS FOR THROWING THE DRY PARTICULATE MATERIAL AT HIGH VELOCITY IN THE DIRECTION TOWARD SAID SURFACE, A HOUSING ENCLOSING SAID THROWING MEANS HAVING AN OPENING THROUGH WHICH THE PARTICULATE MATERIAL IS THROWN AGAINST SAID SURFACE, MEANS FOR ESTABLISHING A SEALING RELATIONSHIP ABOUT SAID OPENING BETWEEN THE HOUSING AND SAID SURFACE TO CONFINE THE PARTICULATE MATERIAL, DIRT AND DUSTS WITHIN THE SEALED SPACE, MEANS FOR COLLECTING THE SPENT PARTICULATE MATERIAL AT THE BOTTOM PORTION OF THE HOUSING AND FOR INTRODUCING AIR INTO THE HOUSING FOR AIR WASHING THE SPENT PARTICULATE MATERIAL TO REMOVE DIRT, AND DUST, RECYCLING THE WASHED PARTICULATE MATERIAL FOR FEED TO THE THROWING MEANS, A DUST COLLECTOR FOR RECEIVING THE DIRT AND DUST FROM WITHIN THE HOUSING FOR SEPARATION THEREOF AND MEANS FOR MAINTAINING SUBATMOSPHERIC CONDITIONS WITHIN THE HOUSING TO GUIDE THE AIR FLOW THROUGH THE HOUSING AND ABOUT SAID SEALING MEANS TO MINIMIZE THE EXHAUST OF DIRT AND DUST INTO THE ATMOSPHERE AND IN WHICH THE SUPPORT MEANS FOR SAID HOUSING INCLUDES MEANS FOR MOVEMENT OF THE HOUSING IN THE VERTICAL DIRECTION, MEANS FOR MOVEMENT OF THE HOUSING IN THE HORIZONTAL DIRECTION AND MEANS FOR MOVEMENT OF THE HOUSING IN THE DIRECTION TOWARD AND AWAY FROM THE SURFACE AND MEANS FOR MOUNTING THE HOUSING FOR ROCKING MOVEMENT ABOUT ITS PITCH AND YAW AXES TO ADJUST THE HOUSING WITH CHANGE IN CONTOUR OF THE SURFACE, AND SENSING MEANS ABOUT THE OPENING AUTOMATICALLY TO ADJUST THE HOUSING FOR CHANGE IN CONTOUR ABOUT THE PITCH AXIS AND/OR THE YAW AXIS AND FOR MOVEMENT OF THE HOUSING IN THE DIRECTION TOWARD AND AWAY FROM THE SURFACE OF AND FOR SHUTTING OFF THE FEED TO PARTICULATE MATERIAL IN THE ABSENCE OF A SEALING RELATIONSHIP BETWEEN THE HOUSING AND SURFACE.
