Abstract
A transportable holding tank for containing clean water and for accepting waste from a stripe removal system. The holding tank is carried on a flatbed vehicle and requires less deck space, thus effectively increasing the cargo-carrying capacity of the vehicle compared with that available if the vehicle were carrying a conventional round or elliptical holding tank. Construction of the tank enables the holding tank to withstand a partial vacuum imposed for pumping waste into the tank. Hooks secured inside of the tank permit a bag for separating solid waste from liquid waste for easy disposal of semi dried materials.
Claims25
A rectangular transportable holding tank system, comprising:
- a holding tank having a floor panel, a top panel, a front side wall between the floor and the top, a left side wall between the floor and the top, a right side wall between the floor and the top and a rear opening between the floor and the top;
- a door hingedly secured to said right side wall and configured to enclose said rear opening in a watertight manner;
- an inlet for allowing a combination of air, water and debris to enter said tank;
- a first outlet for connection to a source of vacuum;
- a plurality of hooks secured within said tank, said hooks constructed and arranged to secure a bag in a substantially open position within said holding tank, said bag positioned to receive said combination of air, water and debris entering said inlet, said bag constructed and arranged to retain said debris while allowing said air and said water to flow through said bag.

A process of utilizing a holding tank for removal of roadway markings comprising the steps of:
- 1. providing a holding tank having a vacuum tank portion and a water tank portion with a connection valve therebetween;
- 2. closing of said connection valve;
- 3. inserting a filter bag in said vacuum tank;
- 4. creating a vacuum in said vacuum tank by use of a vacuum pump powered by an internal combustion engine;
- 5. directing ultra high pressure water from said water tank at a material to be removed creating an air, water and debris slurry, said slurry drawn into said vacuum tank, said slurry being trapped in said filter bag.
- 6. breaking of the vacuum when said vacuum tank reaches full capacity;
- 7. draining water from said vacuum tank through said filter bag;
- and
- repeating steps 1-8 until said filter bag is filled.

A process of utilizing a holding tank for removal of roadway markings comprising the steps of:
- 1. providing a holding tank having a vacuum tank portion and a water tank portion with a connection valve therebetween;
- 2. opening said connection valve;
- 3. inserting a filter bag in said vacuum tank;
- 4. creating a vacuum in said vacuum tank as well as said water tank by use of a vacuum pump powered by an internal combustion engine;
- 5. directing ultra high pressure water at a material to be removed creating a debris slurry, said slurry drawn into said vacuum tank being trapped in said filter bag.
- 6. allowing water to pass from said vacuum tank through said connection valve to said water tank when the water level rises to the level of said connection valve;
- 7. closing of said connection valve releasing vacuum from said water tank;
- 8. draining of water from said water tank via a drain valve;
- 9. closing said drain valve;
- 10. opening said connection valve;
- 11. repeating steps 1-10 until said filter bag is filled.
8 more elements
A mobile stripe removal system comprising in combination:
- a truck, said truck including a prime mover and an elongated frame;
- a rectangular transportable holding tank tiltably mounted on said frame, said holding tank including, a floor panel, a top panel, a front side wall between the floor and the top, a left side wall between the floor and the top, a right side wall between the floor and the top and a rear opening between the floor and the top, a door hingedly secured to said right side wall and configured to enclose said rear opening in a watertight manner, an inlet for allowing a combination of air, water and debris to enter said tank, a first outlet for connection a source of vacuum, a plurality of hooks secured within said tank, said hooks constructed and arranged to secure a bag in a substantially open position within said holding tank, said bag positioned to receive said combination of air, water and debris entering said inlet, said bag constructed and arranged to retain said debris while allowing said air and said water to flow through said bag for retention in said tank, a dividing member attached to said floor, said top, said left side wall and said right side wall in a watertight manner to define a first vacuum tank and a second water tank;
- a water pump secured to said frame and selectively connectable to said second water tank, said water pump powered by an internal combustion engine, said pump capable of supplying at least two gallons of water per minute pressurized to at least twenty five thousand pounds per square inch.
- a vacuum pump secured to frame, said vacuum pump powered by an internal combustion engine for creating a negative pressure within said first vacuum tank;
- a ramp pivotally connected to said frame, said ramp movable between a lowered position to provide a pathway for a self propelled tractor and a raised position for movement of said truck.
