Proppant discharge system and a container for use in such a proppant discharge system

1. A proppant container to transport, store, and discharge fracking proppant when positioned therein, the container comprising:

a box having,

a bottom having a generally planar shape to position the proppant container on a support structure, a pair of side walls and a pair of end walls having a structural cage-like configuration, and a top wall that collectively in combination define a single chamber within the box to receive the fracking proppant when positioned within the proppant container,

an inlet formed in the top wall,

a single outlet formed in the bottom wall, and

a plurality of ramps connected to and extending downwardly from the side walls and the end walls toward the bottom and to the single outlet to channel fracking proppant when positioned within the box toward the outlet;

a box frame that provides structural support for the box when fracking proppant is positioned therein;

an opening adjacent where the ramps join to the side walls and the end walls and extending to the bottom;

ramp supports in the opening each positioned between the ramps and the bottom; and

a gate slidably positioned adjacent the outlet, the gate being movable between a first position covering the outlet and retaining the fracking proppant within the single chamber to a second position opening the outlet to enable the fracking proppant to flow out of the single chamber when positioned on the support structure and connected to an actuator, the actuator moving the gate between the first position and the second position.

2. The container of claim 1 , said box having a capacity of up to 48,000 pounds of fracking proppant, and the ramp supports extend radially inward toward the outlet.

3. The container of claim 1 , wherein the box is adapted to be stackable to minimize the footprint of multiple boxes at a well site when multiple boxes are stored at a well site, and wherein outer peripheral portions of the frame form at least portions of the structural cage-like configuration and are arranged at an outer surface of the sidewalls and the end walls and are vertically aligned with the ramp supports, the structural cage-like configuration having support members being positioned radially farther from the chamber than the outer surface of the sidewalls and the end walls.

4. The container of claim 1 , wherein the container comprises a ten fool ISO container and selectively contains from about 45,000 pounds of fracking proppant to about 48,000 pounds of fracking proppant.

5. A proppant container to transport, store, and discharge fracking proppant when positioned therein, the container comprising:

a box having a generally planar bottom to place the box upon a top surface of a support structure, a pair of side walls and a pair of end walls collectively having a structural cage-like configuration, and a top, the box also having a single chamber within the box to store the fracking proppant therein, an inlet formed in the top, and a single outlet formed in the bottom;

one or more ramps connected to and extending downwardly from the side walls and the end walls to the single outlet to channel proppant when positioned within the box toward the outlet, the one or more ramps comprising a first ramp, a second ramp, a third ramp, and a fourth ramp each having respective lower surfaces exposed adjacent the single outlet in the bottom, and the outer surfaces of the one or more ramps are exposed between ramp supports positioned between the ramps and the bottom;

a frame that provides structural support for the box; and

a gate positioned adjacent the outlet, the gate being slidably movable between a first position covering the outlet to a second position opening the outlet, so that actuation of an actuator moves the gate from the first position to the second position.

6. The container of claim 5 , wherein the structural cage-like configuration includes a plurality of support members.

7. The container of claim 6 , wherein the container has an overall length of about 10 feet and wherein the open space exposes outer surfaces of the ramps, and the ramp supports have a lower surface positioned on the bottom.

8. The container of claim 5 , wherein the box is adapted to be stackable with a forklift to minimize the footprint of multiple boxes at a well site when multiple boxes are stored at a well site and so that the forklift can lift and move the box for one or more of: stacking the box, transporting the box, and positioning the box toward or away from a proppant discharge location.
