System of delivering and storing proppant for use at a well site and container for such proppant
View Patent ↗A method of delivering proppant to a well site has the steps of transporting a load of proppant in a vessel to a desired location, moving the load of proppant from the vessel into a container so as to create a proppant-loaded container, unloading the proppant-loaded container into a pneumatic bulk trailer, and transporting the unloaded proppant in the pneumatic bulk trailer to well site. The container is placed onto a bed of a truck and moved in proximity to the vessel. The proppant-loaded container is placed onto a tilting mechanism and then tilted so that the proppant is discharged through a flow gate of a container into a hopper. The proppant in the hopper can then be conveyed to the pneumatic bulk trailer.
1. An apparatus for proppant storage, the apparatus comprising:
a container having a bottom wall and a top wall and a pair of side walls and a pair of end walls, said pair of side walls extending between said pair of end walls and between said bottom wall and said top wall, said container having an interior volume;
a hatch positioned on said top wall, said hatch being openable to so as to allow the proppant to be introduced into said interior volume of said container; and
a flow gate positioned on one of said of pair of end walls, said flow gate being openable so as to allow the proppant to flow outwardly of said interior volume of said container, said one of said pair of end walls being inset inwardly of an end of said pair of side walls and inwardly of an end of said bottom wall and inwardly of an end of said top wall.
2. The apparatus of claim 1 , said one of said pair of end walls having a generally convex shape.
3. The apparatus of claim 1 , further comprising:
an inlet affixed to at least one of said pair of end walls, said inlet communicating with said interior volume of said container, said inlet suitable for allowing proppant or air to be introduced into said interior volume of said container.
4. The apparatus of claim 3 , further comprising:
a vent opening to said interior volume, said vent formed at an upper portion of said one of said pair of end walls.
5. The apparatus of claim 1 , further comprising:
a longitudinal member positioned in said interior volume of said container, said longitudinal member having one end affixed to one of said pair of end walls and an opposite end affixed to another of said pair of end walls.
6. The apparatus of claim 1 , further comprising:
a first cross member positioned in said interior volume of said container, said first cross member having one end affixed to one of said pair of side walls and an opposite end affixed to the other of said pair of side walls.
7. The apparatus of claim 6 , further comprising:
a second cross member positioned in said interior volume of said container and in spaced parallel relationship to said first cross member, said second cross member having one end affixed to the one of said pair of side walls and an opposite end affixed to the other of said pair of side walls.
8. The apparatus of claim 1 , said flow gate positioned on said one of said end walls generally adjacent said bottom wall, said flow gate being slidable between a closed position and an opened position.
