Abstract

A configurable nozzle includes a nozzle body having a reception chamber configured to receive an application mixture. The nozzle body includes a nozzle orifice. At least one orifice assembly is coupled with the nozzle body, the at least one orifice assembly includes an orifice plate movably coupled with the nozzle body. The orifice plate extends along at least a portion of the nozzle orifice, and movement of the orifice plate changes one or more of the size or shape of the nozzle orifice. An orifice actuator is coupled with the orifice plate, and the orifice actuator is configured to move the orifice plate.

First claim

The invention claimed is:

1. A fluid application system comprising:
at least one source of a carrier fluid and an injection product in communication with at least one configurable nozzle;
at least one sensor interposed between the at least one source and the at least configurable nozzle, the at least one sensor configured to measure at least one of flow rate or pressure of one or more of the carrier fluid or the injection product;
the at least one configurable nozzle is configured to dispense a mixture of the carrier fluid and the injection product with one or more of a specified spray pattern or a specified droplet size, the configurable nozzle includes at least one orifice assembly coupled with a nozzle body, the at least one orifice assembly includes:
at least one orifice plate movably coupled with the nozzle body at a nozzle orifice, the nozzle orifice at a distal end of the nozzle body and configured to dispense the mixture of the carrier fluid and the injection product out of the nozzle, and the at least one orifice plate is configured to change an orifice profile of the nozzle orifice with movement relative to the nozzle body; and
an orifice actuator coupled with the orifice plate, the orifice actuator is configured to move the orifice plate; and

an orifice control unit in communication with the orifice actuator and the at least one sensor, wherein the orifice control unit is configured to control the at least one orifice plate and the orifice profile with the orifice actuator according to the measured flow rate or pressure of one or more of the carrier fluid or the injection product, and the orifice control unit in combination with the movable at least one orifice plate are configured to control one or more of the specified spray pattern or specified droplet size.

2. The fluid application system of claim 1 , wherein the at least one sensor includes at least one of a flow meter or a pressure differential sensor.

3. The fluid application system of claim 1 , wherein the at least one source of the carrier fluid and the injection product includes:
a carrier fluid source; and
an injection product source separate from the carrier fluid source.

4. The fluid application system of claim 3 comprising an injection interface coupled with the configurable nozzle, the injection interface is configured to locally inject an injection product from the injection product source to the carrier fluid from the carrier fluid source at the configurable nozzle.

5. The fluid application system of claim 1 , wherein the fluid application system includes a plurality of operating conditions including at least a first operating condition and a second operating condition; and
in the first operating condition one or more of the carrier fluid or the injection product are delivered at a first flow rate and a first pressure; and
in the second operating condition one or more of the carrier fluid or the injection product are delivered at a second flow rate and a second pressure, and at least one of the first flow rate is less than the second flow rate or the first pressure is less than the second pressure.

6. The fluid application system of claim 5 , wherein the orifice profile includes a plurality of nozzle orifice sizes, the orifice control unit is configured to control the orifice plate according to the measured flow rate or pressure from the at least one sensor; and
in the first operating condition the orifice control unit positions the orifice plate at a first location with a corresponding first nozzle orifice size;
in the second operating condition the orifice control unit positions the orifice plate at a second location with a corresponding second orifice size greater than the first nozzle orifice size; and
in each of the first and second operating conditions the orifice control unit and the orifice plate at the respective first and second locations are configured to maintain one or more of the specified spray pattern or the specified droplet size.

7. The fluid application system of claim 1 , wherein the orifice plate includes a spherical orifice plate, and the nozzle body includes a plate seat rotatable-coupled with the spherical orifice plate.

8. The fluid application system of claim 7 , wherein the spherical orifice plate includes a plate port, and the orifice actuator is configured to rotate the spherical orifice plate and the plate port relative to the nozzle orifice to change the orifice profile.

9. The fluid application system of claim 1 comprising a blending assembly in communication with the at least one configurable nozzle, the blending assembly includes:
a blending port upstream from the at least one configurable nozzle; and
a choke element configured to control the opening of the blending port between at least open and closed configurations.

10. The fluid application system of claim 9 , wherein the blending port includes an element seat; and
in the closed configuration the choke element is seated along the element seat;
in the open configuration the choke element is decoupled from the element seat; and
in an intermediate configuration the choke element is interposed between the closed and open configurations.

11. The configurable nozzle of claim 9 , wherein the choke element includes one or more of a needle valve operator, a butterfly valve operator, or solenoid operated valve operator.
