Bin aerator assembly or unit

Abstract

Abstract The device is installed from outside a wall of a bin or hopper containing pulverulent material; and as such it basically comprises an oblong diffusion unit having a stamped sheet metal body plate, a mesh diffusion screen of truncated pyramidal cross section mounted fixedly forwardly of the plate, and a nipple extending rearwardly of the latter. Pursuant to the invention, the diffuser unit is part of an oblong kit like unit which permits the latter''s quick and easy mounting to the bin wall at a rectangular wall opening which receives the unit from the outside. The unit is clamped and sealed to the wall using a subassembly of (a) a flat mounting plate on which said unit is backed and laterally confined; (b) an inner sealing gasket between that plate and the body plate of the unit; (c) an outer sealing gasket interposed between the mounting plate and the inner surface of the bin wall; (d) a U-shaped spring steel clamp bridge or bracket, whose legs straddle the rectangular wall opening at either side of a central opening in the bracket; and (e) a take-up and clamping nut which threads on the diffusion unit''s nipple as the latter is telescoped through the hole of the bracket. In installing the diffusion unit, as preliminarily assembled to the mounting plate and sealing gaskets of the oblong kit unit, it is slipped through an enlarged rectangular oblong opening in the bin wall (but still less in both dimensions than the plate area), then brought into internally registered overlap across the wall opening, whereupon the clamp bridge or bracket is slidingly applied to the rear air nipple of the unit, with said bracket transversely spanning said opening and tightly taken up by the clamping nut as applied to the nipple.
