Abstract

Apparatuses, systems, and methods are disclosed for a spray nozzle 100, 200, 600. A spray nozzle 100, 200, 600 includes a housing 102 with an inlet 104 and/or a nose cone 106. An axis of an inlet 104 is disposed perpendicular to an axis of a nose cone 106, the housing 102 comprising an internal chamber formed within the housing 102. A spray nozzle 100, 200, 600 includes a nozzle holder 204. A nozzle holder 204 is disposed within an internal chamber of a body. A nozzle holder 204 is secured at a nozzle seat 202 coupled to a nose cone 106. A distal end of a nozzle holder 204 is free to rotate within an internal chamber of a housing 102 along a conical path having a vertex at approximately a nozzle seat 202 of a body. A nozzle holder 204 comprises an internal fluid channel to direct a fluid stream from a distal end of the nozzle holder 204 to a nozzle seat 202.

First claim

The invention claimed is:

1. A spray nozzle comprising:
a housing comprising an inlet and a nose cone, wherein an axis of the inlet is disposed perpendicular to an axis of the nose cone, the housing comprises an internal chamber formed within the housing, and the inlet comprises a rotational jet with multiple orifices;
a nozzle holder disposed within the internal chamber of the housing, the nozzle holder secured at a nozzle seat coupled to the nose cone, an end of the nozzle holder distal from the nozzle seat, the distal end of the nozzle holder being free to rotate within the internal chamber of the housing along a conical path, the conical path having a vertex at approximately the nozzle seat of the body, the nozzle holder comprising an internal fluid channel to direct a fluid stream from the distal end of the nozzle holder to the nozzle seat;
an insert coupled to an interior of the nozzle holder, the insert having an internal geometry with multiple sectors forming multiple fluid channels within the interior of the nozzle holder to collimate the fluid stream as it passes through the nozzle holder; and
an end cap disposed in the housing opposite the nose cone, the end cap comprising a post disposed centrally on the end cap and external to the nozzle holder such that an exterior of the nozzle holder orbits around an exterior of the post within the internal chamber.

2. The spray nozzle of claim 1 , wherein the inlet is disposed on a side of the housing at a location to direct the fluid stream into the internal chamber and motivate the rotation of the nozzle holder.

3. The spray nozzle of claim 2 , wherein the inlet comprises a rotational jet aligned to direct the fluid stream into the internal chamber off-center to apply a force to the nozzle holder.

4. The spray nozzle of claim 1 , wherein the spray nozzle is adjustable to change a cone angle of the fluid stream as it exits the spray nozzle.

5. The spray nozzle of claim 1 , wherein the spray nozzle is adjustable to change a volume of the fluid stream.

6. The spray nozzle of claim 1 , wherein the spray nozzle is adjustable to change a rotational speed of the nozzle holder.

7. The spray nozzle of claim 1 , wherein the nozzle holder comprises an o-ring coupled to the nozzle holder between the nozzle seat and the distal end, the o-ring forming a friction barrier between a surface of the internal chamber and the nozzle holder during rotation of the nozzle holder.

8. The spray nozzle of claim 1 , wherein the housing further comprises an o-ring disposed on a surface of the internal chamber and forming a friction barrier between the surface of the internal chamber and the nozzle holder during rotation of the nozzle holder.

9. The spray nozzle of claim 1 , wherein the post comprises a guide to interface with the distal end of the nozzle holder.

10. The spray nozzle of claim 9 , wherein the post disposed centrally on the end cap protrudes into the internal chamber.

11. The spray nozzle of claim 9 , wherein the end cap is adjustable to change the interface between the guide and the nozzle holder.

12. The spray nozzle of claim 9 , wherein the end cap is removable from the housing.

13. The spray nozzle of claim 1 , further comprising:
one or more sensors configured to detect one or more of a rotation rate of the nozzle holder and a flow rate of the fluid stream; and
a communications module configured to transmit the one or more of the rotation rate and the flow rate to a base station for the spray nozzle.

14. A system for spray washing, the system comprising:
a spray washing cabinet;
a spray nozzle coupled to the spray washing cabinet, the spray nozzle comprising:
a housing comprising an inlet and a nose cone, wherein an axis of the inlet is disposed perpendicular to an axis of the nose cone, the housing comprises an internal chamber formed within the housing, and the inlet comprises a rotational jet with multiple orifices;
a nozzle holder disposed within the internal chamber of the housing, the nozzle holder secured at a nozzle seat coupled to the nose cone, an end of the nozzle holder distal from the nozzle seat, the distal end of the nozzle holder being free to rotate within the internal chamber of the housing along a conical path, the conical path having a vertex at approximately the nozzle seat of the body, the nozzle holder comprising an internal fluid channel to direct a fluid stream from the free end of the nozzle holder to the nozzle seat;
an insert coupled to an interior of the nozzle holder, the insert having an internal geometry with multiple sectors forming multiple fluid channels within the interior of the nozzle holder to collimate the fluid stream as it passes through the nozzle holder; and
an end cap disposed in the housing opposite the nose cone, the end cap comprising a post disposed centrally on the end cap and external to the nozzle holder such that an exterior of the nozzle holder orbits around an exterior of the post within the internal chamber.

15. The system of claim 14 , wherein the spray washing cabinet comprises a plurality of spray nozzles.

16. The system of claim 15 , further comprising a control module for the plurality of spray nozzles, wherein the plurality of spray nozzles each comprise a communications module in wireless communication with the control module and one or more sensors, the communications modules transmitting data from the one or more sensors wirelessly to the control module.

17. A method for spray washing, the method comprising:
directing a fluid stream into a nozzle housing of a spray nozzle at an inlet at a point to rotate the fluid stream within an internal chamber of the nozzle housing, the inlet comprising a rotational jet with multiple orifices;
rotating a nozzle holder along a conical path within the internal chamber of the nozzle housing such that an exterior of the nozzle holder orbits around an exterior of a post within the internal chamber, the post disposed centrally on an end cap and external to the nozzle holder, the end cap disposed in the nozzle housing opposite the nose cone;
directing the fluid stream into the nozzle holder as the nozzle holder rotates;
directing the fluid stream through an insert coupled to an interior of the nozzle holder, the insert having an internal geometry with multiple sectors forming multiple fluid channels within the interior of the nozzle holder to collimate the fluid stream as it passes through the nozzle holder; and
directing the fluid stream to a spray washing target.

18. The method of claim 17 , further comprising adjusting the spray nozzle to apply an effect on the fluid stream to correspond to the spray washing target.

19. The method of claim 18 , wherein adjusting the spray nozzle comprises at least one of adjusting a rotational speed of the nozzle holder, a cone angle of the fluid stream directed to the spray washing target, and a volume of the fluid stream directed to the spray washing target.
