Compartmentalized pneumatic vessel filtering and unloading system

A system for receiving, transporting, and discharging dry flowable material, comprising:

• an elongated transportable vessel formed by enclosing wall structure,
• means for supporting aid vessel such that its length is generally horizontal,
• two spaced apart bulkheads separating said vessel into three compartments comprising a center compartment and two end compartments for carrying dry flowable material,
• said wall structure of said vessel at its upper end having three separate openings extending therethrough leading to said three compartments respective for receiving dry flowable material into said three compartments,
• three lids for closing said three openings respectively whereby said vessel comprising said three compartments may be pressurized with air,
• passageway means extending between said two end compartments and said center compartment for equalizing the pressure therein,
• filter means extending across said passageway means for blocking the flow of dry flowable material through said passageway means but allowing the flow of air therethrough,
• three separate material discharge means coupled to said wall structure of said vessel at its lower end and leading to said three compartments respectively for removing dry flowable material from each of said compartments,
• a first material discharge conduit coupled to said material discharge means of said two end compartments for directing the flow of dry flowable material removed from said two end compartments,
• a second material discharge conduit coupled to said material discharge means of said center compartment for directing the flow of dry flowable material removed form said center compartment,
• a pneumatic conduit means coupled to said two end compartments for pressurizing said two end compartments when said three lids are closed whereby all three of said compartments will be equally pressurized by way of said passageway deans during the removal of dry flowable material from said two end compartments or from said center compartment by way of their discharge means and discharge conduit respectively.
