Cold steel slurry box device

A heated slurry box comprising:

• a vacuum tank which can be withstand vacuum pressure, the vacuum tank having one or more openings, wherein the openings may be closed to seal the vacuum tank when a vacuum pump is fluidly attached to the vacuum tank, the vacuum tank constructed from a steel with a ductile brittle transition temperature less than −60 degrees Celsius;
• a structure attached to the vacuum tank wherein the structure allows the vacuum tank to be transported on a vehicle, wherein the structure has a bottom, the structure constructed from a steel with a ductile brittle transition temperature less than −50 degrees Celsius;
• a mechanical bay wherein the mechanical bay contains a power unit and a hydraulic pump, wherein the power unit is adapted to heat a fluid which is circulated producing a heated fluid flow, wherein the hydraulic pump produces flow and pressure to operate hydraulic functions, wherein the power unit is attached to the mechanical bay using quick disconnect connectors, wherein the power unit can be removed from the mechanical bay;
• a tailgate attached to the vacuum tank, wherein the tailgate is attached to the vacuum tank with at least a tailgate hinge, wherein the tailgate may pivot on the tailgate hinge to open and close, wherein the tailgate hinge has an axis which is parallel to the bottom of the structure, wherein the tailgate is opened vertically, the tailgate constructed from a steel with a ductile brittle transition temperature less than −60 degrees Celsius;
• a hook point attached to the structure to allow the structure to be pulled onto a roll-off vehicle, the hook point constructed from a steel with a ductile brittle transition temperature less than −60 degrees Celsius;
• a stacking mount system and a stacking leg system, wherein the stacking mount system and the stacking leg system fit together to allow multiple slurry boxes to be stacked vertically;
• a front pipe flange which is jacketed, wherein the front pipe flange comprises an inner surface and an exterior surface, wherein the heated fluid flow is circulated between the inner surface and the exterior surface;
• a rear pipe flange which is jacketed, wherein the rear pipe flange comprises an inner surface and an exterior surface, wherein the heated fluid flow is circulated between the inner surface and the exterior surface;
• a thermo relief valve mounted on the vacuum tank;
• a manhole attached to the vacuum tank;
• a set of lift hooks attached to the structure;
• and
• a base wheel set attached to the structure.
