Telescopic Coal Feeding Pipe Status Detection for Jamming Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The central telescopic feeding pipe in coal storage Eurosilo experiences jamming due to coal dust and water vapor adhesion, leading to operational instability and damage, with existing systems lacking effective status detection to prevent such issues.
Innovation Solution
A status detection apparatus is installed between the Eurosilo feeding inlet and connecting section, comprising an upper connection fixing body, lower connection sliding body, spring body, and detector, which detects relative displacement to monitor the telescopic status of the central telescopic feeding pipe without altering its nested structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the central telescopic feeding pipe is used for coal conveying, then the coal storage operation is enabled, but the pipe experiences jamming due to coal dust and water vapor adhesion
Solution Approach 1:
The patent installs detection devices (such as displacement sensors, temperature sensors, and vibration sensors) on the telescopic feeding pipe to monitor its operational status in real-time. These sensors detect parameters like pipe displacement, temperature changes, and vibration patterns that indicate jamming conditions. When abnormal conditions are detected, the system provides feedback signals to the control unit, which can then alert operators or automatically adjust operations to prevent damage, thus resolving the contradiction between maintaining productivity and ensuring reliability.
2Adaptability or versatility
If the nested structure of the central telescopic feeding pipe is maintained, then the telescopic function is preserved, but the structure is vulnerable to damage from jamming
Solution Approach 1:
The patent implements detection devices and control systems that monitor the telescopic feeding pipe before jamming causes structural damage. The system detects early signs of jamming (such as abnormal displacement patterns, temperature increases, or vibration changes) and triggers alerts or automatic shutdowns. This preliminary detection and response mechanism allows the nested telescopic structure to maintain its adaptability while protecting it from damage by addressing jamming issues before they compromise structural integrity.
3Device complexity
If no status detection system is installed, then the device complexity is low, but jamming conditions cannot be identified timely
Solution Approach 1:
The patent introduces a monitoring system with detection devices (displacement sensors, temperature sensors, vibration sensors) and a control unit that provides real-time feedback on the telescopic feeding pipe's status. This feedback mechanism enables timely identification of jamming conditions while keeping the added complexity manageable through integrated control logic and standardized sensor implementations, thus resolving the contradiction between system simplicity and reliability.
