Transport container having compartments that can be individually pressurized
First Claim
1. A container for use in transporting particulate materials, said container comprising:
- (a) a plurality of product compartments, with each such compartment having a material outlet in communication therewith through which particulate material in the compartment may be discharged;
(b) a gas-tight bulkhead separating a pair of adjacent product compartments;
(c) an unloading system that is adapted for removal of particulate materials from the product compartments, said unloading system including;
(i) a source for supplying a pressurizing gas;
(ii) one or more top air conduits connecting the pressurizing gas source to the product compartments for conveying pressurizing gas to the product compartments;
(iii) a material conveying conduit that is in fluid communication with a plurality of the material outlets, which conduit includes a discharge end through which particulate material may be unloaded;
which unloading system is adapted for;
(iv) selectively pressurizing one or more of the product compartments so that particulate material may be discharged through the material outlet of a product compartment that is pressurized;
(v) entraining material that is discharged through a material outlet in the material conveying conduit and conveying such material to the discharge end of the conduit.

Abstract
A container for use in transporting particulate materials includes a plurality of product compartments, with each such compartment having a material outlet in communication therewith through which particulate material in the compartment may be discharged. The container also includes a gas-tight bulkhead separating a pair of adjacent product compartments, and an unloading system that is adapted for removal of particulate materials from the product compartments. The unloading system includes a source for supplying a pressurizing gas, and one or more top air conduits connecting the pressurizing gas source to the product compartments for conveying pressurizing gas to the product compartments. The unloading system also includes a material conveying conduit that is in fluid communication with one or more of the material outlets and which includes a discharge end through which particulate material may be unloaded. The unloading system is adapted for selectively pressurizing one or more of the product compartments so that particulate material may be discharged through the material outlet of a product compartment that is pressurized. The unloading system is also adapted for entraining material that is discharged through a material outlet in the material conveying conduit and conveying such material to the discharge end of the conduit.

7. A container for use in transporting particulate materials, said container comprising:
-
(a) a front product compartment having a front material outlet that is in communication therewith;
(b) a middle product compartment having a middle material outlet that is in communication therewith;
(c) a first gas-tight bulkhead between the front compartment and the middle compartment;
(d) a rear product compartment having a rear material outlet that is in communication therewith;
(e) a second gas-tight bulkhead between the middle compartment and the rear compartment;

10. A method for unloading particulate material from a product compartment of a container, which method comprises:
-
(a) providing a container for use in transporting particulate materials, said container comprising;
(i) a plurality of product compartments, with each such compartment having a material outlet in communication therewith through which particulate material in the compartment may be discharged;
(ii) a gas-tight bulkhead separating a pair of adjacent product compartments;
(iii) a source for supplying a pressurizing gas;
(iv) one or more top air conduits connecting the pressurizing gas source to the product compartments for conveying pressurizing gas to the product compartments;
(v) a material conveying conduit that is in fluid communication with a plurality of the material outlets, which conduit includes a discharge end through which particulate material may be unloaded;
(b) pressurizing a product compartment without pressurizing all of the product compartments;
(c) discharging particulate material through the material outlet of a product compartment which is pressurized into the material conveying conduit;
(d) entraining material in the material conveying conduit and conveying such material to the discharge end of the conduit. - View Dependent Claims (11, 12, 13)
