Nano-Sand Mill Screen Dredging for Continuous Static Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sand mills require shutdown for filter disc replacement and lack real-time monitoring of blockage, leading to reduced unloading efficiency.
Innovation Solution
A nano-sand mill with static discharge at the tail end of a turbine, featuring a dredging mechanism and monitoring modules to continuously dredge the screen and monitor discharge speed, allowing real-time detection and prevention of blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sand mill uses a filter disc for discharging ground materials, then the discharge function is achieved, but the filter disc blocks during operation requiring shutdown for replacement
Solution Approach 1:
The patent applies mechanical vibration through a vibrating motor that drives the filter disc to vibrate. This vibration prevents material accumulation and blockage on the filter disc surface, enabling continuous operation without shutdown for cleaning or replacement, thus resolving the contradiction between reliability and productivity
Solution Approach 2:
The filter disc is designed to be self-cleaning through vibration-induced material ejection. The system automatically prevents blockage without requiring external intervention or shutdown, making the discharge system self-maintaining and enabling continuous operation
2Reliability
If the filter disc is replaced regularly, then the blockage problem is prevented, but the replacement timing cannot be determined by actual use state
Solution Approach 1:
The patent incorporates a sensor that detects the blockage state of the filter disc in real-time and provides feedback to the control system. This allows the system to determine the actual use state and replace the filter disc only when necessary, rather than following a fixed schedule, thus reducing unnecessary replacement time while maintaining reliable blockage prevention
3Reliability
If the sand mill shuts down to replace the filter disc, then the blocked filter disc is replaced, but the materials cannot be unloaded through the filter disc during replacement
Solution Approach 1:
The vibrating motor continuously vibrates the filter disc during operation, preventing material blockage and eliminating the need for shutdown to clear blockages. This maintains continuous discharge capability while ensuring the filter disc remains functional, resolving the contradiction between reliability and discharge continuity
