Filed:

Feb 3, 2005

Appl. No.:

11/050309

Inventors:

James E. Messer - Westlake OH, US
Dennis Lettkeman - Watonga OK, US
Salvatore C. Immordino - Trevor WI, US
Timothy Ross - Kannapolis NC, US

Assignee:

United States Gypsum Company - Chicago IL

International Classification:

B05B 7/06

US Classification:

239432, 239422, 239433, 239428, 2394193

Abstract:

An apparatus for mixing an additive into a fluid to form a settable mixture includes a main fluid passageway having an inlet for receiving a supply of the fluid and an outlet for dispensing the fluid, the passageway having a longitudinal axis. The apparatus includes a control valve defining a portion of the main fluid passageway and configured for selectively controlling the flow of fluid in the passageway, an additive injector disposed in the passageway and having an emitter disposed in close relationship with the axis and oriented toward the outlet. A static mixer is disposed between the injector and the outlet for enhancing the uniform mixing of the additive and the fluid. Connection points between the inlet, the valve and the static mixer are configured for smooth transition of fluid and the prevention of at least one of the collection and premature setting of the mixture.

International Classification:

US Classification:

2394193

Abstract:

A slurry spray machine for spraying a settable slurry includes a main passageway configured for receiving a supply of pressurized slurry and having a supply end and an outlet end opposite the supply end. A first compressed gas inlet is disposed intermediate the supply and outlet ends and in fluid communication with the passageway for introducing a first supply of pressurized gas into the slurry, and a second pressurized gas inlet is disposed closer to the outlet end than the first inlet and in fluid communication with the passageway for introducing a second supply of pressurized gas into the slurry. A pressurized supply of adjuvant is provided in fluid communication with the second pressurized gas inlet for providing a blended gas to the second gas inlet. At least one valve is provided for controlling the flow of slurry through the passageway and the flow of the first and second gases into the passageway. Prior to the pressurized ejection of the slurry from the outlet end, the first gas is injected into the slurry, and the blended gas is mixed with the slurry and the first pressurized gas between the first gas inlet and the outlet end.
