Bubble Breaker Conduit for Resin Degassing Overflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing degassing apparatuses face challenges with resin overflow due to the rapid release of gas bubbles, which can lead to inefficient degassing processes and increased cycle times.
Innovation Solution
A bubble breaker is introduced into the degassing apparatus, featuring a conduit system with a decreasing cross-sectional area that allows gas bubbles to rise and burst at the surface, preventing overflow and reducing degassing cycle time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gas bubbles are allowed to expand and release rapidly from the resin, then degassing efficiency is improved, but resin overflow occurs and cycle time increases
Solution Approach 1:
The bubble breaker divides the single large bubble into multiple smaller bubbles by forcing them through multiple conduits with decreasing cross-sectional areas. This segmentation allows the bubbles to be released in a controlled manner rather than all at once, preventing overflow while maintaining degassing efficiency.
Solution Approach 2:
The conduits have varying cross-sectional areas along their length, with the cross-section decreasing from inlet to outlet. This local variation in geometry creates different flow conditions at different locations, enabling controlled bubble expansion and release that prevents overflow.
2Reliability
If gas bubbles are allowed to expand and release rapidly from the resin, then trapped air is removed effectively, but resin overflow occurs
Solution Approach 1:
By forcing bubbles through multiple conduits that divide the flow, the system segments the bubble release into multiple smaller streams. This prevents the harmful effect of resin overflow while maintaining effective removal of trapped air, as the segmented bubbles still achieve充分 expansion and release.
Solution Approach 2:
The bubble breaker acts as an intermediary device between the resin and the atmosphere. It provides a controlled interface where bubbles can expand and release without directly causing resin overflow, mediating the harmful effect by controlling the release mechanism.
3Object-generated harmful factors
If manual or auto-venting is used to control bubble release, then resin overflow is prevented, but degassing cycle time increases
Solution Approach 1:
The bubble breaker is a passive device that automatically controls bubble release through its conduit geometry without requiring external control systems or manual intervention. The decreasing cross-sectional area of the conduits self-regulates the bubble expansion and release, eliminating the need for venting operations and reducing cycle time.
Solution Approach 2:
The invention replaces the mechanical control systems (manual venting or auto-venting mechanisms) with a passive geometric structure. The conduit shape itself performs the control function that previously required active mechanical systems, simplifying the overall system and reducing cycle time.
