Abstract
A rotating radiator screen has a series of fins surrounding the peripheral edge of the screen at its interface with a wall surface of the machine on which the screen is mounted. An annular baffle on the wall surface circumscribes the fins and cooperates with them in producing positive pressure and an axially outwardly moving curtain of air in the vicinity of the interface so as to oppose the ingress of ambient air and foreign materials at that location.
Claims9
In a machine having a wall surface provided with an inlet through which ambient air is drawn, filtration apparatus comprising:
- a rotary screen covering said inlet for filtering debris from ambient air passing through the screen as air is drawn into the inlet,
- said screen having an axis of rotation and a peripheral edge adjacent said wall surface;
- a series of external fins around the screen at said edge and disposed radially outboard of the inlet for creating an outflow of air from the screen adjacent said edge as the screen rotates about said axis;
- and
- an annular baffle surrounding the fins radially outboard thereof and projecting axially outwardly from said wall surface.
