ABSTRACT:
A system for confinement and removal of air-borne dust emitted during discharge delivery of particulate solids from an elevated supply source and through an enclosed descending column. The enclosed column has a delivery spout at the discharge end, the spout including a generally enclosed shroud with an open bottom wall defining the discharge opening. An arcuate lead-in flow diverter plate is coupled to the underside of the descending enclosed column and curves generally inwardly of the column. An abutment plate is disposed forwardly of the flow diverter plate at the opposed end of the discharge opening and is positioned along the normal flow path of particulate solids passing from the lead-in flow diverter plate so as to define a dynamic seal with the particulate solids moving across the discharge opening. A dust collecting duct is coupled through the spout shroud above the discharge opening so as to receive and remove a flow of dust laden air from the discharge spout to a solid-air separator means. The structural arrangement generates a flow pattern for the grain with reduced vertical velocity at the output, the reduction being accomplished, at least in part, through interaction among the grain kernels.
