Abstract
Abstract Tube bundle cleaning apparatus is disclosed in which cleaning is effected by high pressure water jets impinging upon the tubes of the bundle. The tube bundle is supported on power rollers and a pair of carriages are disposed on opposite sides of the bundle. Each carriage supports a rotatable cleaning head and a non-rotatable cleaning head, both of which are adjustably positionable on the carriage for obtaining optimum location relative to different size tube bundles. The non-rotatable cleanig head includes plural sets of jet nozzles, each set being adjustable in the vertical direction to provide optimum spacing relative to different size tubes to be cleaned. The carriages are mounted on respective tracks for reversibly traversing the tube bundle in repeated cycles to clean a selected swath of the bundle. When the selected swath is cleaned, the tube bundle is rotated to another angular position by the power rollers for cleaning of another swath. The process is repeated until the entire tube bundle is cleaned.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
A tube bundle cleaning apparatus comprising: a set of power-driven rollers adapted to receive a tube bundle for cleaning, a horizontal track extending parallel to said rollers, a carriage movably supported on said track, a non-rotatable cleaning head adjustably mounted on said carriage and including plural nozzles, each pointed transversely of said bundle and adapted to be connected with a source of high pressure fluid, first head positioning means for adjustably positioning said head on the carriage in the vertical direction, second head positioning means for adjustably positioning said head on the carriage in the horizontal direction toward and away from said tube bundle, nozzle positioning means for adjustably positioning each of said plural nozzles by translational movement relative to each other on said head, and means for moving the carriage along said track between the ends of said tube bundle.
Claim 2
Dependent Claim
141 words
A tube bundle cleaning apparatus comprising: a set of power-driven rollers adapted to receive a tube bundle for cleaning, a horizontal track extending parallel to said rollers, a carriage movably supported on said track, a non-rotatable cleaning head adjustably mounted on said carriage and including plural nozzles, each pointed transversely of said bundle and adapted to be connected with a source of high pressure fluid, first head positioning means for adjustably positioning said head on the carriage in the vertical direction, second head positioning means for adjustably positioning said head on the carriage in the horizontal direction toward and away from said tube bundle, nozzle positioning means for adjustably positioning each of said plural nozzles by translational movement relative to each other on said head, and means for moving the carriage along said track between the ends of said tube bundle.
Claim 3
Dependent Claim
46 words
The invention as defined in claim 1 including: a rotary cleaning head mounted on said carriage and including a rotary member with a pair of diametrically opposite nozzles each pointed in a horizontal plane and adapted to be connected with a source of high pressure fluid.
Claim 4
Dependent Claim
43 words
The invention as defined in claim 1 wherein, said non-rotatable head comprises, a base member, a plurality of nozzle holders, each of the nozzle holders being slidably mounted on the base member whereby said plural nozzles can be positioned relative to each other.
Claim 5
Dependent Claim
58 words
The invention as defined in claim 3 including, a vertical slideway and a horizontal slideway, one of said slideways being mounted on said carriage and the other slideway being mounted on said one slideway, said base member being mounted on said one slideway whereby said base members can be positioned vertically and horizontally relative to said tube bundle.
Claim 6
Dependent Claim
60 words
The invention as defined in claim 3 wherein, each of said nozzle holders comprises a flat plate disposed in a vertical plane, successive ones of the flat plates being disposed face-to-face, each of said plates being slidably mounted for positioning in a vertical direction relative to each other whereby the respective nozzles may be adjustably positioned in the vertical direction.
Claim 7
Dependent Claim
28 words
The invention as defined in claim 5 wherein, plural nozzles are mounted on each of said flat plates and are spaced from each other in the vertical direction.
Claim 8
Dependent Claim
203 words
Tube bundle cleaning apparatus comprising: a set of power-driven rollers adapted to receive a tube bundle for cleaning and to rotate said tube bundle about its longitudinal axis for positioning said bundle for cleaning, first and second horizontal tracks extending parallel to said rollers on opposite sides thereof, first and second carriages movably supported on said first and second tracks respectively, first and second non-rotatable cleaning heads adjustably mounted, respectively, on said first and second carriages, each of said cleaning heads including plural nozzles each of said nozzles being pointed transversely of said bundle in the horizontal plane and adapted to be connected with a source of high pressure fluid, first and second vertical positioning means for adjustably positioning said first and second heads on said first and second carriages, respectively, in the vertical direction, first and second horizontal positioning means for adjustably positioning said first and second heads on the first and second carriages, respectively, in the horizontal direction toward and away from said tube bundle, means for adjustably positioning each of said plural nozzles by translational movement on said respective heads relative to each other, and means for moving the carriage along said track between the ends of said tube bundle.
