Split Crucible Collection Assembly for Low-Loss Isotope Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for separating and purifying radioisotopes like Lu-177 are inefficient and result in significant material loss, especially for rare and expensive elements like ytterbium and lutetium, limiting their reuse and recycling.
Innovation Solution
A split collection crucible assembly with removably coupled plate and crucible portions, combined with a modular crucible loading unit, allows for precise alignment and easy access, minimizing material loss during phase separation and collection processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional collection crucible assemblies are used, then material collection is achieved, but material loss is significant and access to collected material is difficult
Solution Approach 1:
The collection crucible assembly is divided into separate segments: the collection crucible, cooling plate, and cover are separable components that can be disassembled for easy access to collected material while maintaining structural integrity during operation
Solution Approach 2:
The assembly transitions from a static sealed structure to a dynamic configurable structure where components can be readily assembled and disassembled, enabling easy access to collected material without compromising operational sealing
2Manufacturing precision
If fixed alignment methods are used, then alignment precision is achieved, but device complexity increases
Solution Approach 1:
Flat mating surfaces and precision-machined interfaces create equipotential contact areas between components, ensuring accurate alignment through surface contact rather than complex mechanical alignment features
Solution Approach 2:
The components possess self-aligning interfaces with flat mating surfaces that automatically achieve precise alignment when brought together, eliminating the need for external alignment mechanisms or complex adjustment procedures
3Productivity
If traditional processing methods are used, then processing is completed, but recycling and reprocessing efficiency is low
Solution Approach 1:
The separable assembly design enables complete recovery of collected material by disassembling components for full access, allowing near-100% recovery of rare earth elements for recycling and reprocessing without material loss
Solution Approach 2:
The assembly uses compatible material combinations with appropriate thermal expansion coefficients and surface properties that maintain sealing and structural integrity through multiple thermal cycles, enabling repeated use and recycling
