ABSTRACT:
A rotary drum air filter has a drive tire where a rubber tire runs against a drive rim attached to the drum co-axial therewith. A seal on the forward part of the drum rides upon a conic section on the scroll. Differential air pressure across the drum holds the seal against the conic section on the scroll. A unitary rigid manifold with a plurality of pipes is mounted for rotation about its longitudinal axis. Therefore, by rotation of the manifold, nozzles in the pipes can be exposed for adjustment and inspection. Nozzle tips in each the pipes extending from the manifold are adjustable so as to regulate the distance from the lip of the nozzle tip to the surface of the drum. For use with an atmosphere heavily laden with lint, a two-part nozzle is used so that the leading edge of the nozzle can be spaced away from the filter medium on the drum surface to accommodate a thick layer of lint which accumulated on the drum surface. The drum wheels or supports for the perimeter of the drum are made by cutting half of each wheel from sheetmetal with a guided cutter. The two halves(semidiscs) are welded together and a strap or band is welded to the perimeter to form a rigid cylindrical rim thereon.
