ABSTRACT:
A transportable vessel is provided formed by enclosing wall structure. Two spaced apart bulkheads separate the vessel into three compartments defined as a center compartment and two end compartments for carrying dry flowable material. The wall structure of the vessel at its upper end has at least three openings extending therethrough leading to the three compartments respectively for receiving dry flowable material into the three compartments. Three lids are provided for closing the three opening respectively whereby the vessel including the three compartments may be pressurized with air. A passageway extends through the upper portion of each of the bulkheads and a filter extends across each of the passageways for blocking the flow of dry flowable material through the passageways but allowing the flow of air therethrough. At least three separate material discharge hoppers are coupled to the wall structure of the vessel at its lower end for removing dry flowable material from each of the compartments. A first material discharge conduit is coupled to the hoppers of the two end compartments for directing the flow of dry flowable material removed from the two end compartments away from the vessel. A second material discharge conduit is coupled to the hopper of the center compartment for directing the flow of dry flowable material removed from the center compartment away from the vessel. A pneumatic conduit is coupled to the two end compartments for pressurizing the two end compartments whereby all three of the compartments will be equally pressurized by way of the bulkhead passageways, during the removal of dry flowable material from the two end compartments or from the center compartment.
