Application April 16, 1954, Serial No. 423,366 11 Claims. (Cl. 299-62) (Granted under Title .35, U. S. Code (1952), sec. 266) The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royaltie thereon ortherefor.
'The present invention concerns a nozzle and in .particular, concerns a nozzle assembly. that in part rotates and in part is nonrotary.
The invention relates to an improvement in nozzles of the type useful in apparatusfor cleaning and conditioning drums and similar containers as described in United States Patent 2,244,040 of June 3, 1941, to John R. Alexander for Apparatus for Cleaning and Conditioning Drums.
In cleaning apparatus of the type described in the above-identified patent, a problem exists because the bung hole in the type of oil drum to be cleaned is located near the periphery of the drum head so that there is difliculty in inserting a nozzle therein and obtaining a substantially uniform impingement and. distribution of the cleaning fluids over the interiorsurfaces of the drum. Proper cleaning will not result unless all of the surfaces and every part thereof are contacted with the cleaning fluids in a satisfactory manner. In addition, several fluids are required to clean, treat, syphon, dry and preserve a drum. In the prior art there have been no satisfactory nozzles for obtaining uniform impingement and distribution of the several cleaning fluids.
This invention provides a novel type of nozzle in which part of the nozzle rotates and part of the nozzle i nonrotary to provide uniform impingement and distribution of cleaning fluids. Furthermore, the nozzles have a multiplicity of individual jets of different sizes and shapes whereby different fluids may pass simultaneously or in sequence through the nozzles. The nozzles because .of the numerous sizes and shapes of jets therein may remain in the bung hole of the barrel to be cleaned without removal therefrom during a multiplicity of the cleaning, treating, syphoning, drying and preserving operations.
Another problem exists because the bung holes in drums to be cleaned are customarily small and the nozzle must therefore be even smaller because an area of sufficient size must be left between the exterior surface of the nozzle and the inner threaded surface of the bung flange to permit rapid escape and complete drainage of the cleaning fluids and residues from the interior of the container during the draining operation.
The nozzle assembly of the present invention is of minimum size and designed with multiple coaxial pipes constructed of thin walled tubing to permit a large flow of liquids through the pipes to the nozzles and at the same time to provide a maximum area for drainage from the drum being cleaned.
An object of the invention is to provide a nozzle.
Another object is to provide a nozzle havinga part that rotates and a part that is nonrotary.
Another object is to provide a nozzle that i suitable for use in apparatus for cleaning and conditioning drums.
Another object is to provide a .nozzle that-insures sub- States Patent 28 are in axial alignment.

2,797,964 latented July 2, 1957 2 stantially uniform impingement. and distribution of cleaning -fiuid from the nozzle over the interior surface of the drum to be cleaned.
Another object is to provide a nozzle assembly that can be left in place in the drum to be cleaned while different fluids are. fed through different pipe to different jets in the nozzle either simultaneously or in sequence.
Another object is to provide a nozzle assembly that can be placed in a small bung holeof the drum to -be cleaned and provide a maximum space between the nozzle assembly and the bung hole to permitdrainage of fluid from the drum.
Other objects and many of the attendant advantages of this invention will be readily appreciated-a thersame becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
Fig. l is a front elevation-of a; preferred embodiment of the invention,
Fig. 2 is a top plan view ofFig; 1, and
Fig. 3 is a longitudinal cross-section along line 3'3 of Fig. 1.
In the drawings there is shown a nozzle assembly, 11 comprising a turbine casing 12 having a disk-shaped base 13, a cylindrical casing wall 14, and adisk-shaped turbine casing cover 15. A bearing ring 16 depends axially from turbine casing base 13. Turbine casing W3ll14 is provided with a turbine casinginlet 21 and a turbine casing outlet 22. Mounted above turbine casing 12 is a steam casing 25 having a cylindrical steam casing wall 26 provided with asteam chamber inlet nipple 27. Turbine casing cover 15 serves as the base for steam casing 25.
Above steam casing 25 is located an air casing 28 having a disk-shaped air casing base 29, a cylindrical air casing wall 31 provided with an air inlet pipe 33 and-a diskshaped air casing cover.32. Air casingbase 29 serves as the cover for steam casing 25.
-Turbine casing 12. and steam casing 25 and air casing A plurality of bolts 35 extend through bases. Hand 29 and through covers 15 and 32 peripherally thereof and each bolt 35 i provided with a nut 36 whereby turbine casing 12 and steam casing-25 and air casing 28 are locked together in fluid-tight relation.
A liquid pipe 41- extends axially through the three casings and-at its lower end projects downwardly through bearing ring 16 for connection to a liquid nipple 42. A bearing43 is-mounted in bearing ring 16 and supports liquidpipe. 41 for rotation relative to the-casings. Packing 44 is provided to prevent leakage.
A steam pipe 57 is coaxial with liquid pipe 41 and jackets liquid pipe'41 and extends through air casing 28. Steam pipe-57 is-fixedly mounted at its lower end in air casing base 29 and opens into the interior of steam casing 25 and into communication with steam chamber inlet 27. Steam pipe 57 at its upper end terminates in a cylindrical nozzle 61 below bulbous nozzle 47. Cylindrical nozzle 61 by means of set screws 63 ismounted in nonrotary relation at the upper end of steam pipe- 57. Cylindrical nozzle 61 is provided with a first series of .jets 65 that extend radially-and are upwardly directed pipe 57.
An air pipe 67 is coaxial with steam pipe 57 and jackets steam pipe 57. Air pipe 67 is fixedly mounted at its lower endin air casing cover 32 and opens into the interior of air casing 28 and in communication with air inlet pipe 33; Airpipe 67 at its upper end terminates in cylindrical nozzle 61 which is provided with a second series of jets 71 that extend radially andare .upw-ardly directed below jets 65 and open outwardly from nozzle 61 and at their inner ends are in communication with the upper end of air pipe 67.
A turbine wheel 75 is mounted on liquid pipe 41 for rotation therewith and is locked in place by set screw 76. Turbine wheel 75 is located in turbine casing 12 and is adapted to be driven by fluid passing from turbine casing inlet 21 through turbine casing 12 to turbine casing outlet 22. Rotation of turbine wheel 75 causes rotation of liquid pipe 41 and bulbous nozzle 47 carried thereby. Thrust washers 81 and 82 are provided adjacent to hub of turbine wheel 75 and packing 85 and gland nut 87 are provided for preventing leakage of fluid.
A pipe support 92 is affixed to the air casing wall 31.
In operation the lower end of liquid pipe 41 is connected by means of nipple 42 with a suitable source of liquid, steam chamber inlet nipple 27 is connected to a suitable source of steam, and air inlet pipe 33 is connected to a suitable source of dehydrated air. Conventional valves (not shown) are used to regulate fiow of liquid, steam, and dehydrated air to clean and condition a drum. Turbine casing inlet 21 is connected to a suitable source of compressed air and is regulated by a conventional valve (not shown) to rotate turbine wheel 75.
Liquid fed into nipple 42 and liquid pipe 41 passes upwardly and sprays outwardly through slots 51 and 52 of bulbous rotary nozzle 47. Steam passing inwardly through steam chamber inlet nipple 27 passes upwardly through steam pipe 57 and sprays outwardly through jets 65 in cylindrical nonrotary nozzle 61. Dehydrated air passing inwardly through air inlet nipple 33 passes upwardly through air pipe 67 and sprays outwardly through jets 71 in cylindrical nonrotary nozzle 61. Compressed air passing through turbine casing inlet 21 drives turbine wheel 75 to rotate turbine wheel 75 and thereby cause rotation of nozzle 47. Outward spraying of liquid, steam, and dehydrated air can be simultaneous or in sequence.
Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
