Abstract:
1. A frac sand transporting container comprising: a first plurality of walls having a first pair of parallel longitudinal walls and a second pair of parallel transverse walls, with said second pair of parallel transverse walls perpendicular to said first pair of parallel longitudinal walls, with one wall of said pair of transverse walls having a door disposed thereupon, and also having a floor and a roof perpendicular to said plurality of walls; a second plurality of frac sand input ports disposed atop said roof with each of said frac sand input ports coupled with a first output pipe located in situ at a frac sand processing facility; a third plurality of quick-connect valves attached to said plurality of walls, for controlling frac liquid flow into like third plurality of input ports interconnected therewith; a fourth plurality of quick-connect valves also attached to said plurality of walls, for controlling frac liquid flow out of like fourth plurality of output discharge ports interconnected therewith; a crossbrace and truss framework enclosed within and affixed to said first plurality of walls, said floor and said roof, for reinforcing the strength thereof; a dual modality hopper assembly disposed within and affixed to said crossbrace and truss framework and forming a sealable enclosure for receiving from said second plurality of frac sand input ports frac sand when configured in a first modality, with said frac sand collected and stored in a central chamber member disposed therewithin; said dual modality hopper assembly receiving from said third plurality of frac liquid input ports frac liquid when configured in a second modality, with said frac liquid collected and stored in a bilateral elongated bladder member disposed longitudinally of said central chamber member throughout the length thereof; said central chamber member further disposed parallel to and longitudinally of said floor throughout the length thereof, and comprising a pair of elongated arm members pivotably affixed thereto at their vertex to a hinge member, with said pair of elongated arm members, in turn, pivoting from a first position disposed at an angle of about 30° relative to said floor to a second position disposed at an angle of about 85° relative to said floor; a fifth plurality of output discharge ports disposed upon an external transverse surface of said dual modality hopper assembly, with each said output discharge port thereof coupled to a second discharge pipe located in situ at a well site for transfer of said frac sand from said central chamber member downhole; each output discharge port of said fourth plurality of output discharge ports coupled to a second discharge pipe for transfer of said frac liquid downhole or transfer to a third discharge pipe located in situ at a recycle facility; an elongated linear hydraulic valve disposed longitudinally of said frac sand container floor and comprising an elongated fixed outer tube disposed annularly of an elongated slidable inner tube, with each of said inner tube and said outer tube having a like sixth plurality of holes disposed upon and throughout the surface thereof; and said inner tube hydraulically urged to slidably either align its sixth plurality of holes with corresponding sixth plurality of holes of said outer tube, thereby emplacing said elongated linear valve in an open position allowing outflow therethrough, or to misalign its sixth plurality of holes with corresponding sixth plurality of holes of said outer tube, thereby emplacing said elongated linear valve in a closed position preventing outflow therethrough.
