Filed:

Oct 23, 2001

Appl. No.:

10/039835

Inventors:

James Tyson - Pennsauken NJ 08109

International Classification:

B22D 1116

US Classification:

702183, 702 39, 702 54, 702 56, 702105, 702159, 702171, 702182

Abstract:

Sound detection techniques and sound discrimination techniques are used to analyze the real time sounds generated during the operation of cleaning heads operating within a vessel to determine if the cleaning heads are operating properly. During a typical cleaning operation pressurized cleaning solution is dispensed through a rotating nozzle assembly inside the vessel. As the nozzles rotate the spray moves about the interior of the vessel creating a unique sound pattern. By placing one or more pickups on the exterior of the vessel the sound is captured and fed to an analyzing device for analysis. Key properties such as, but not limited to, sound pressure levels, amplitude variations, spectral content, and rotational information are extracted and analyzed against the reference parameters.

International Classification:

B08B 7/04

US Classification:

Abstract:

Sound detection techniques and sound discrimination techniques are used to analyze the real time sounds generated during the operation of cleaning heads operating within a vessel to determine if the cleaning heads are operating properly. During a typical cleaning operation pressurized cleaning solution is dispensed through a plurality of rotating nozzles inside the vessel. As the nozzles rotate the spray moves about the interior of the vessel creating a unique sound pattern. By placing one or more pickups on the exterior of the vessel the sound is captured and fed to an analyzing device for analysis. The peaks in the captured sound pattern are divided into the number of nozzles and stored in an equal number of buffers. After averaging, the buffers a compared to each other. One buffer that significantly differs froms the others indicates that the nozzle associated with that buffer is defective.
