Abstract

Apparatus features a signal processor or signal processing module configured to: receive signaling containing information about an acoustic noise profile that is directly measured and generated by a slurry hitting a probe configured in a part of a cyclone; and determine corresponding signaling containing information about the status of the part of the cyclone, based upon the signaling received. The signal processor or signal processing module is configured to provide the corresponding signaling, including where the corresponding signaling provided contains information about whether the part of the cyclone is damaged or worn. The part of the cyclone is an apex of the cyclone, and the corresponding signaling contains information about the status of the apex of the cyclone.

First claim

What is claimed is:

1 . Apparatus having a cyclone, comprising:
a probe mounted or arranged inside a part of a cyclone, and configured to measure an acoustic noise profile generated by a slurry flowing in the part of the cyclone and hitting the probe, and provide signaling containing information about the acoustic noise profile generated; and a signal processor or signal processing module configured to:
receive the signaling; and
provide corresponding signaling containing information about the status of the part of the cyclone by correlating statistical fluctuations in the acoustic noise profile measured and generated of the slurry hitting the probe in real time, based upon the signaling received;
wherein a correlation of the statistical fluctuations is based on associated statistical fluctuations in an associated acoustic noise profile of a worn or damaged part of the cyclone having higher or less stable statistical fluctuations in probe measurements, and corresponding statistical fluctuations in a corresponding noise profile of a non-worn or non-damaged part of the cyclone having lower or more stable statistical fluctuations in the probe measurements than the associated acoustic noise profile of the worn or damaged part of the cyclone.

2 . Apparatus according to claim 1 , wherein the corresponding signaling provided contains information about whether the part of the cyclone is damaged or worn.

3 . Apparatus according to claim 1 , wherein the part of the cyclone is an apex of the cyclone, and the corresponding signaling contains information about the status of the apex of the cyclone.

4 . Apparatus according to claim 1 , wherein the acoustic noise profile indicates the status of the part of the cyclone.

5 . Apparatus according to claim 1 , wherein the signal processor or signal processing module is configured, through measurements of a cyclone overflow stream in real time, to determine individual cyclone wear or damage.

6 . Apparatus according to claim 1 , wherein the signal processor or signal processing module is configured to determine trending capability of cyclone wear or damage that enables predictive maintenance strategies based on condition monitoring instead of time-based replacement.

7 . Apparatus according to claim 1 , wherein the signal processor or signal processing module is configured to provide diagnostic capability in real time while the cyclone is operating so the cyclone does not have to be taken out of operation for manual inspection.

8 . Apparatus according to claim 1 , wherein the apparatus comprises a mineral extraction processing system.

9 . Apparatus according to claim 1 , wherein the probe is a particle size tracking probe mounted or arranged inside the part of the cyclone.

10 . Apparatus according to claim 1 , wherein the cyclone includes a cyclone part with the probe configured therein.

11 . Apparatus according to claim 1 , wherein the apparatus comprises a mineral extraction processing system including at least one cyclone having an overflow pipe with the probe mounted or arranged in the overflow pipe.

12 . Apparatus according to claim 1 , wherein the information about the status of the part of the cyclone includes data to generate a graph of the statistical fluctuations in the acoustic noise profile, which once generated can be visually interpreted to determine wear or damage of the part of the cyclone.

13 . A method comprising:
mounting or arranging a probe inside a part of a cyclone; measuring an acoustic noise profile generated by a slurry flowing in the part of the cyclone and hitting the probe, and providing signaling containing information about the acoustic noise profile generated; receiving in a signal processor or signal processing module the signaling; and providing from the signal processor or signal processing module corresponding signaling containing information about the status of the part of the cyclone by correlating statistical fluctuations in the acoustic noise profile measured and generated of the slurry hitting the probe in real time, based upon the signaling received; wherein a correlation of the statistical fluctuations is based on associated statistical fluctuations in an associated acoustic noise profile of a worn or damaged part of the cyclone having higher or less stable statistical fluctuations in probe measurements, and corresponding statistical fluctuations in a corresponding noise profile of a non-worn or non-damaged part of the cyclone having lower or more stable statistical fluctuations in the probe measurements than the associated acoustic noise profile of the worn or damaged part of the cyclone.

14 . A method according to claim 13 , wherein the corresponding signaling provided contains information about whether the part of the cyclone is damaged or worn.

15 . A method according to claim 13 , wherein the part of the cyclone is an apex of the cyclone, and the corresponding signaling contains information about the status of the apex of the cyclone.

16 . A method according to claim 13 , wherein the acoustic noise profile indicates the status of the part of the cyclone.

17 . A method according to claim 13 , wherein the method comprises configuring the signal processor or signal processing module, through measurements of a cyclone overflow stream in real time, to determine individual cyclone wear or damage.

18 . A method according to claim 13 , wherein the signal processor or signal processing module is configured to determine trending capability of cyclone wear or damage that enables predictive maintenance strategies based on condition monitoring instead of time-based replacement.

19 . A method according to claim 13 , wherein the signal processor or signal processing module is configured to provide diagnostic capability in real time while the cyclone is operating so the cyclone does not have to be taken out of operation for manual inspection.

20 . A method according to claim 13 , wherein the method further comprises configuring the probe to provide the signaling to the signal processor or signal processing module.

21 . A method according to claim 20 , wherein the probe is a particle size tracking probe.
