On-line degassing device with detachable sealing end cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile phase on-line degassers face challenges in maintaining and replacing the degassing pipe, which is prone to damage due to its fixed position within the chamber, making maintenance inconvenient.
Innovation Solution
The on-line degassing device features a detachable sealing end cover and positioning joints that allow the degassing pipe to be easily removed and replaced, along with enhanced sealing mechanisms using a sealing plug and ring to improve stability and prevent gas ingress, and multiple degassing chambers connected through a communicating groove for efficient vacuumization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the degassing pipe is fixed in the degassing chamber, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The device is divided into modular components: the degassing chamber, the sealing end cover, and the degassing pipe assembly. The sealing end cover can be detached to provide access to the degassing pipe, allowing replacement without dismantling the entire chamber structure. This segmentation enables easy maintenance while preserving structural integrity during operation.
Solution Approach 2:
The sealing end cover is designed to be detachable rather than fixed, transforming the static structure into a dynamic one that can be opened for maintenance and closed for stable operation. This allows the system to switch between operational stability and maintenance accessibility as needed.
2Ease of operation
If the sealing end cover is detachably connected, then the ease of operation is improved, but the reliability deteriorates
Solution Approach 1:
The sealing end cover is extracted as a separate, detachable component from the main chamber body. This allows easy access to the degassing pipe for replacement while incorporating sealing mechanisms (sealing plugs and sealing rings) that ensure reliability when the cover is reattached, thus maintaining both ease of operation and system reliability.
3Productivity
If multiple degassing chambers are connected through a communicating groove, then the productivity is improved, but the device complexity increases
Solution Approach 1:
Multiple degassing chambers are connected through a common communicating groove that provides shared access to the vacuum joint. This merging approach allows a single vacuum pumping device to service multiple chambers simultaneously, improving productivity while avoiding the need for separate vacuum systems for each chamber, thus limiting the increase in complexity.
