Abstract
An apparatus for spraying mixtures of solid and liquid materials includes a tank; a pump; an inlet line from the tank to the pump; a return line from the pump to the tank; a spraying nozzle; a nozzle supply line from the pump to the nozzle; a nozzle to the tank; and first and second valves for regulating the respective amounts of mixtures to be fed either to the nozzle, the nozzle supply line, the nozzle return line or the return line from the pump to the tank. By providing two separate valves and return lines, one at the pump and one at the nozzle, constant agitation of the tank contents is maintained and clogging anywhere in the system, particularly in the nozzle hose, is avoided.
Claims11
An apparatus for spraying mixtures of solid and liquid materials onto any desired area, comprising:
- a tank;
- a pump;
- an inlet line from said tank to said pump;
- a return line from said pump to said tank;
- a discharge nozzle;
- a nozzle supply line from said pump to said discharge nozzle;
- first valve means for regulating the respective amounts of mixture being fed to said return line and to said nozzle supply line;
- a nozzle return line from said nozzle supply line to said tank, said nozzle return line intersecting said nozzle supply line at said nozzle;
- and
- second valve means, at said intersection of said nozzle return line and said nozzle supply line, for regulating the respective amounts of mixture being fed to said discharge nozzle and to said nozzle return line, said second valve means being regulatable among a first configuration at which all flow in said nozzle supply line enters said nozzle, none being recycled through said nozzle return line, a second configuration at which all flow in said nozzle supply line enters said nozzle return line, none entering said nozzle, and intermediate configurations permitting varying ratios of flow to said nozzle and said nozzle return line.
