Abstract
A liquid slurry spraying system for spraying highly viscous slurries, including those with solids content, while maintaining the slurry in agitated condition for optimum discharge. The spraying system includes a nozzle body with a liquid flow passage having a liquid slurry inlet adjacent an upstream end and a spray tip at a downstream end, a valve needle supported in the liquid flow passage for reciprocating movement between spray tip closing and opening positions, and a bladed rotor having a plurality of vanes rotatably supported on the valve needle for rotation as an incident to the direction of liquid slurry from said liquid inlet when the valve needle is in an open position for agitating the liquid slurry for direction to the spray tip.
Claims18
A liquid slurry spraying system comprising:
- a nozzle body having a spray tip with a discharge orifice at a downstream end of the nozzle body;
- said nozzle body having a liquid flow passage communicating with said spray tip;
- a supply of liquid slurry;
- said nozzle body having a liquid slurry inlet communicating with said liquid flow passage from said liquid slurry supply for directing liquid slurry into said flow passage for discharge from said spray tip discharge orifice;
- an elongated rod supported axially within said liquid flow passage;
- and a bladed rotor rotatably supported on said elongated rod within said nozzle body adjacent an upstream end of said liquid flow passage across from said liquid inlet for rotation relative to said elongated rod as an incident to the direction of liquid slurry from said liquid inlet into said liquid flow passage for agitating the liquid slurry for direction to said spray tip;
- wherein said elongated rod is the piston rod of a piston assembly that is operable for reciprocating the piston rod between a forward spray tip closing position interrupting the discharge of liquid slurry from said spray tip discharge orifice and a retracted open position for enabling the direction of liquid slurry from said liquid inlet, through said flow passage, and discharge from said spray tip discharge orifice.
A liquid slurry spraying system comprising:
- a nozzle body having a spray tip with a discharge orifice at a downstream end of the nozzle body;
- said nozzle body having a liquid flow passage communicating with said spray tip;
- a supply of liquid slurry;
- said nozzle body having a liquid slurry inlet communicating with said liquid flow passage from said liquid slurry supply for directing liquid slurry into said flow passage for discharge from said spray tip discharge orifice;
- a valve needle supported in said liquid flow passage for reciprocating movement between a forward spray tip closing position interrupting the discharge of liquid slurry from said spray tip discharge orifice and a retracted open position for enabling the direction of liquid slurry from said liquid inlet, through said liquid flow passage, and discharge from said spray tip discharge orifice;
- and a bladed rotatably supported on said valve needle within said nozzle body adjacent an upstream of said liquid flow passage across from said liquid inlet for rotation as an incident to the direction of liquid slurry from said liquid inlet into said liquid flow passage for agitating the liquid slurry for direction to said spray tip.
A liquid slurry spraying system comprising:
- a nozzle body having a spray tip with a discharge orifice at a downstream end of the nozzle body;
- said nozzle body having a liquid flow passage communicating with said spray tip;
- said nozzle body having a liquid inlet communicating with liquid flow passage from a liquid slurry supply for directing liquid slurry into said flow passage for discharge from said spray tip discharge orifice;
- a valve needle supported in liquid flow passage for reciprocating movement between a forward spray tip closing position interrupting the discharge of liquid slurry from said spray tip discharge orifice and a retracted open position for enabling the direction of liquid slurry from said liquid inlet, through said flow passage, and discharge from said spray tip discharge orifice;
- and a bladed rotor having a plurality of circumferentially spaced vanes rotatably supported on said valve needle for rotation as an incident to the direction of liquid slurry through said liquid inlet into said liquid flow passage for agitating the liquid slurry for direction to said spray tip.
