Conductive Wiring for Ceramic Filter Plate Breakage Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Filter plate breakages in rotary vacuum disc filters used for dewatering mineral concentrates lead to costly downtime and potential domino effects, as broken plates can cause adjacent plates to break, resulting in significant operational disruptions and expenses.
Innovation Solution
Integration of conductive wiring along the filter plates to form a continuous electrical circuit that breaks upon plate breakage, allowing for immediate monitoring and cessation of operation, thereby preventing further plate damage and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If filter plates operate continuously without monitoring, then productivity is maintained, but plate breakages cause domino effects leading to increased downtime and costs
Solution Approach 1:
The patent implements a monitoring system that provides feedback on the condition of filter plates. Sensors detect parameters such as vibration, temperature, or pressure changes that indicate plate degradation or breakage, allowing the system to respond before catastrophic failure occurs. This feedback mechanism enables continuous operation while maintaining reliability by alerting operators to plate issues in real-time.
Solution Approach 2:
The patent employs preventive measures by monitoring plate conditions and issuing warnings before actual breakage occurs. By detecting early signs of plate degradation through sensors and analysis systems, the invention allows for scheduled maintenance and plate replacement before failures happen, preventing the domino effect of consecutive plate breakages while maintaining continuous productivity.
2Reliability
If filter plates are monitored continuously, then plate breakage can be detected early, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical monitoring systems with simpler sensor-based detection methods. Instead of using elaborate mechanical sensors and linkages to detect plate conditions, the invention employs electronic sensors that can detect vibration, temperature, or pressure changes, significantly reducing mechanical complexity while improving detection capability.
Solution Approach 2:
The monitoring system is designed to serve multiple functions: detecting plate breakage, monitoring plate degradation, and potentially detecting other filter system anomalies. By creating a multi-functional monitoring system, the patent reduces overall device complexity compared to having separate specialized systems for each detection function.

AI summary
A ceramic filter plate (22) is provided with a conductive wiring (70, 71) extending along the filter plate to form a continuous electrical circuit and arranged to break upon breakage of the filter plate. The integrity of the conductive wiring (70, 71) is monitored, and the operation, particularly the rotation, of the disc filter is immediately stopped upon detecting a break of the conductive wiring.
