Abstract
A conveying system for conveying a conveyable material from a hopper where the system includes a fluid port located below the hopper outlet and in a vertical flow path into hopper outlet that can be momentarily opened for an on the go release of a charge of compressed air directly upward into the hopper outlet and into the underside of the bridge in the hopper to either disintegrate or unlock the bridged particles from each other thereby causing the bridged material to fall into the hopper outlet and into the conveying system where the material can be transported to a remote location or to remove any material that may be adhering to the wall during an emptying phase.
Claims10
The method of conveying material from a gravity hopper comprising the steps of;
- directing a conveyable material into a port in the gravity hopper;
- gravitationally directing the conveyable material downward into a converging bin located at the bottom of the gravity hopper;
- conveying the conveyable material away from a gravity hopper outlet;
- momentarily directing a stream of air upward into the gravity hopper outlet;
- and normally maintaining an air pressure on a topside of the conveyable material in the gravity hopper at proximately the same as an air pressure on the underside of the conveyable material in the gravity hopper through directing a stream of air upward into the gravity hopper outlet and opposite to a gravitational flow direction of the conveyable material from the gravity hopper outlet.
