Stripe removal system
View Patent ↗A system for removing paint and other coatings from hard surfaces is mounted on a truck for over-the-road travel. The truck bed carries a high power vacuum pump, a self propelled tractor with an attached blast head, a liquid reservoir, a sump or vacuum tank, and a ramp for loading the tractor. The reservoir is connected to a low pressure pump that transfers water to the high pressure pump. The high pressure pump is connected to the blast head by a high pressure hose. A vacuum hose is connected to the sump which has an internal enclosure for separating the waste materials from the liquid for easy dumping of semi dried materials.
1. A process for removing material comprising the steps of:
1. providing a vacuum tank and a water tank with a connection valve therebetween, closing of said connection valve;
2. inserting a bag constructed from filter material completely within said vacuum tank said bag including an open top;
3. creating a vacuum in said vacuum tank by use of a vacuum pump powered by an internal combustion engine;
4. directing ultra high pressure water at a material to be removed creating a debris slurry, said slurry drawn into said vacuum tank and directed into from top of said open top of said filter bag whereby said debris being trapped in said filter bag;
5. stopping the creation of the vacuum when said vacuum tank reaches full capacity;
6. draining water, but not said debris from said vacuum tank through said filter material, said filter material retaining substantially all said debris; and
7. repeating steps 1-7 until said filter bag is filled.
2. The process for removing material of claim 1 wherein said open top of said filter bag is hung on hooks positioned within said vacuum tank.
3. The process for removing material of claim 2 wherein said hooks are secured to ceiling of said vacuum tank.
4. A process for removing material comprising the steps of:
1. providing a vacuum tank and a water tank with a connection valve there between, opening said connection valve;
2. inserting a bag constructed from filter material completely within said vacuum tank said bag including an open top;
3. creating a vacuum in said vacuum tank by use of a vacuum pump powered by an internal combustion engine;
4. directing ultra high pressure water at a material to be removed creating a debris slurry, said slurry drawn into said vacuum tank and directed into from top of said open top of said filter bag whereby said debris being trapped in said filter bag;
5. 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;
6. closing of said connection valve releasing vacuum from said water side tank;
7. draining of water from said water tank;
8. closing drain valve;
9. opening said connection valve; and
10. repeating steps 1-9 until said filter material is filled.
5. The process for removing material of claim 4 wherein said open top of said filter bag is hung on hooks positioned within said vacuum tank.
6. The process for removing material of claim 5 wherein said hooks are secured to ceiling of said vacuum tank.
