Abstract
An environmentally safe transportable liquid holding tank has an inner tank and a rigid enclosure spaced outwardly therefrom to provide a compartment therebetween. At least one access assembly is provided on the top of the enclosure and the inner tank, and this assembly includes a removable closure on the tank and a displaceable cover over that closure which extends across an upwardly opening recess defined within the access assembly and extending about the closure in the tank. Pump out conduits extend to the upper portion of the enclosure, and wheels are provided on the base of the unit to enable its movement from place to place.
Claims19
An environmentally safe transportable liquid holding tank comprising
- (a) an inner tank having end walls and a peripheral wall and having a top and a bottom;
- (b) a rigid enclosure about said tank and having a top and a bottom with a base wall, end walls, top wall and side walls, at least said end and side walls being spaced outwardly from said end walls and peripheral wall of said inner tank to provide a compartment therebetween equal in volume to at least one-half the volume of said inner tank;
- (c) support elements supporting said inner tank within said enclosure in said spaced relationship;
- (d) a base on which said enclosure is supported;
- (e) at least one access assembly at said top of said enclosure and said inner tank, said access assembly including a removable closure on said inner tank closing an opening into said tank disposed in a substantially horizontal plane, said access assembly defining an upwardly opening recess therewithin and in said peripheral wall of said inner tank extending about said removable closure, and said assembly further having a displaceable cover over said recess to provide an outer closure for the opening in said top of said rigid enclosure over said removable closure on said inner tan;
- (f) a first pump out conduit extending upwardly from said bottom of said inner tank to the upper portion of said enclosure;
- and
- (g) a second pump out conduit extending from the bottom of said compartment defined between said enclosure and inner tank to the upper portion of said enclosure.
An environmentally safe transportable liquid holding tank comprising
- (a) an inner tank having end walls and a peripheral wall and having a top and a bottom;
- (b) a rigid enclosure about said tank and having a top and a bottom with a base wall, end walls, top wall and side walls, said base, end and side walls being spaced outwardly from said end walls and peripheral wall of said inner tank to provide a sump therebelow and a compartment therebetween equal in volume to at least one-half the volume of said inner tank;
- (c) support elements supporting said inner tank within said enclosure in said spaced relationship;
- (d) a base on which said enclosure is supported, said base having wheels thereon for transport of the holding tank;
- (e) at least one access assembly at said top of said enclosure and said inner tank, said access assembly including a removable closure on said inner tank closing an opening into said inner tank disposed in a horizontal plane, said access assembly defining an upwardly opening recess therewithin and in said peripheral wall of said inner tank extending about said removable closure and therebelow to provide a catch basin thereabout, said assembly also having a displaceable cover over said recess to provide an outer closure for the opening in said top of said rigid enclosure over said removable closure on said inner tank, a second opening in said inner tank within said enclosure to drain fluid from said catch basin into said inner tank, and a removable cap for said second opening;
- (f) a first pump out conduit extending upwardly from said bottom of said inner tank to the upper portion of said enclosure;
- (g) a second pump out conduit extending from said sump to the upper portion of said enclosure;
- and
- (h) a vent from said enclosure to the atmosphere.
