Abstract
A method and system for trans-loading solid particulates from a hopper to a storage container, by clamping a trough to a discharge gate of the hopper, the trough having an open top, sides, and a bottom, a vacuum pipe extending into the trough, and at least one aerator located on the trough, to which is provided an aerating gas. The method further comprises at least partially evacuating the storage container to cause at least a partial vacuum therein and drawing a vacuum through a conveyor hose connected to the trough.
Claims9
A method of trans-loading solid particulates from a hopper to a storage container, comprising:
- clamping an elongated trough to a discharge gate of said hopper, said trough having an open top, sides and a bottom with at least one wall that slopes downward toward an end wall of the trough, at least one vacuum pipe opening into said end wall of the trough, and at least one aerator located on the trough openings spaced longitudinally along at least one of the sides of the trough;
- at least partially evacuating said storage container to cause at least a partial vacuum therein;
- applying a vacuum to said trough via said vacuum pipe;
- applying a gas to said aerator;
- opening said hopper discharge gate to permit said solid particulates to fall into said trough;
- and
- conveying said solid particulates through said vacuum pipe to said storage container.
A method of trans-loading solid particulates from a hopper to a storage container, comprising:
- clamping a V-shaped trough to a discharge gate of said hopper, said V-shaped trough having two angled side panels which converge at a bottom of the V-shaped trough and first and second vertical end panels, a vacuum pipe extending from outside the V-shaped trough and through the first vertical end panel, and a series of aerators located along each of the angled side panels;
- at least partially evacuating said storage container to cause at least a partial vacuum therein;
- applying a vacuum to said trough via said vacuum pipe;
- applying air pressure to said aerators;
- opening said hopper discharge gate to permit said solid particulates to fall into said V-shaped trough;
- and
- conveying said solid particulates through said vacuum pipe to said storage container.
