ABSTRACT:
A tank for receiving water thereinto, a chemical injector for injecting a measured amount of chemical inhibitor into the water in the tank, a pump placed atop the tank for providing water mixed with the inhibitor chemical under pressure out of the tank for injection into the sandblasting line. There is further provided an air supply for providing pressurized air to operate the pump under a certain pressure and to operate the chemical injector at a certain pressure, there being pressure regulator gauges for regulating same. The system would further comprise a sand pot also providing pressurized sand into the main sandblasting line, wherein compressed air in the system and the chemical injected water feed into the line for providing a continuous source of sand or sand slurry sandblasting under pressure. In this improved system, there is further provided a connector member contained within the sandblasting line for delivering the sand, air and water slurry to the end point or nozzle for use in the actual sandblasting.
