Solution Overview

Problem

Existing methods for determining hydrocyclone wear or damage require the cyclone to be offline, leading to inefficiencies in classification performance and maintenance, as they rely on manual measurements and have limited real-time monitoring capabilities.

Innovation Solution

Implementing a system that uses acoustic noise profiling from a particle size tracking probe to monitor hydrocyclone performance in real-time, allowing for predictive maintenance strategies without requiring the cyclone to be taken out of operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual sampling methods are used to determine hydrocyclone wear or damage, then measurement accuracy can be achieved, but the cyclone must be taken offline resulting in loss of productivity

Engineering Contradiction:

Improvewear detection accuracyVSAvoidclassification performance

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical sampling methods with an acoustic emission detection system. Acoustic sensors mounted on the hydrocyclone housing detect wear-induced acoustic signals in real-time during operation, eliminating the need to take the cyclone offline for manual measurements while maintaining detection accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces acoustic emission signals as an intermediary indicator of wear. Instead of directly measuring wear dimensions (which requires shutdown), the system detects acoustic emissions generated by wear processes, providing indirect real-time monitoring that maintains productivity while enabling accurate wear assessment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If real-time monitoring is implemented using acoustic emission sensors, then productivity is maintained, but device complexity increases

Engineering Contradiction:

Improvecontinuous operation capabilityVSAvoidmonitoring system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent makes the acoustic emission monitoring system multi-functional. The same sensor network and processing system detect multiple wear locations (vortex finder, apex, spigot) and provide both diagnostic information and predictive maintenance capabilities, reducing overall system complexity compared to multiple separate monitoring systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The monitoring system is designed to be self-diagnostic, automatically identifying wear locations and severity levels without requiring external expert intervention. The system self-calibrates and provides automated alerts, reducing operational complexity while maintaining continuous productivity.

Inventive Principle:

Principle #25Self-service

3Measurement precision

If individual cyclone monitoring is implemented, then maintenance precision is improved, but the number of sensors and system complexity increase

Engineering Contradiction:

Improveindividual cyclone wear detectionVSAvoidsensor quantity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the monitoring system into modular acoustic sensor units that can be independently mounted on individual cyclones. Each cyclone can be monitored with its own sensor package, allowing precise individual detection while enabling flexible system configuration - sensors can be added or removed based on specific operational needs without requiring complete system redesign.

Inventive Principle:

Principle #1Segmentation

AI summary

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.
