Abstract:
1. A fast rate, at least partial gravity unloading, relatively large capacity particulate matter storage bin apparatus comprising: (a) a storage bin having a floor and a roof connected by a sheet metal cylindrical vertical wall having inner and outer sides, the cylindrical vertical wall having corrugated inner and outer sides, the storage bin having a bin opening which allows the particulate matter to pass through; (b) a box channel assembly of sheet metal attached to the inner side of the storage bin vertical wall, defining a substantially enclosed channel for flow of particulate matter, having a generally vertical longitudinal axis, and located inside the storage bin between the floor and the roof, the box channel assembly further comprising: (c) so that a substantially continuous channel of sheet metal is defined from above the bin opening to the bin opening for additional strengthening of the vertical side wall of the bin, but to also deter forces on the vertical side wall by controlled flow of particulate matter by the inwardly extending flanges or members through the inlet openings and to deter frictional erosion of the particulate matter and the vertical side wall of the bin by promoting controlled flow through flat sheet metal surfaces of the substantially enclosed sheet metal channel.
