Air Guide Roller Transport for Electrostatic Separator Breakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-coated separators experience frequent breakages due to severe electrostatic charges and friction with rollers in stack equipment, particularly when the binder ratio on the surface is high, leading to failures during transportation.
Innovation Solution
The use of an air guide roller system with controlled air spray to reduce friction and prevent breakages by spraying air onto the separator surface while it travels, adjusting air spray pressure and cycle based on electrostatic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the binder ratio on the separator surface is increased to improve electrostatic characteristics, then the separator's ability to withstand electrostatic charges improves, but friction with rollers increases causing frequent breakages
Solution Approach 1:
Air is introduced as an intermediary substance between the separator and the roller surface. The air layer acts as a mediator that reduces direct contact and friction between the separator and roller, preventing breakages while allowing the separator to maintain its high binder ratio for electrostatic stability
Solution Approach 2:
A pneumatic system is employed where air is supplied through holes in the roller to create an air cushion or air film between the separator and the roller surface. This pneumatic mechanism reduces friction and prevents separator breakage during transportation
2Reliability
If the separator travels through stack equipment with high electrostatic characteristics, then the separator maintains its functional properties, but friction with rollers causes frequent breakages and transportation failures
Solution Approach 1:
Air serves as an intermediary that enables smooth transportation of the separator through the stack equipment. The air layer reduces friction and prevents stick-slip phenomena, allowing continuous and efficient transportation without breakages
Solution Approach 2:
The physical state of the interface between separator and roller is changed from solid-to-solid contact to solid-to-gas contact. This parameter change in the contact medium fundamentally alters the friction characteristics and enables smooth transportation
