Segmented Exhaust Filter for Coating Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exhaust gas filtering systems for coating equipment face inefficiencies due to frequent shutdowns for filter replacement, limited gas flow diameter leading to pressure drops, and challenges in ensuring sealability, which affect production efficiency and vacuum pump performance.
Innovation Solution
An exhaust gas filtering apparatus with detachable and easily replaceable filtering units, a monitoring system for timely replacement, and a design that allows for a larger gas flow diameter to reduce pressure drops, ensuring convenient installation and sealability through mounting components and a sealing ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter flask is used for exhaust gas filtration, then exhaust gas can be filtered, but the filter flask needs frequent replacement causing shutdowns and production efficiency loss
Solution Approach 1:
The exhaust gas treatment system is segmented into multiple independent filter units (first filter unit and second filter unit) that can operate independently. When one filter unit needs replacement, the other continues to filter exhaust gas, allowing maintenance without shutdown and maintaining production efficiency.
2Reliability
If a filter flask with small gas flow diameter is used, then filtration can be achieved, but pressure drop increases causing vacuum pump alarms
Solution Approach 1:
The filter units are designed with a large cross-sectional area (dimensional change from small diameter to large area) to reduce gas flow resistance and pressure drop while maintaining effective filtration capacity.
3Reliability
If the filter flask is replaced frequently, then filtration performance is maintained, but installation and sealability become challenging
Solution Approach 1:
The filter system is divided into separable filter units with standardized mounting structures. Each filter unit can be independently installed and removed without affecting the entire system, making replacement convenient and ensuring proper sealability through dedicated mounting interfaces.
