Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current abrasive recycling systems are unable to effectively differentiate between abrasive particles and foreign materials of similar size, leading to undesirable issues in the final recycled abrasive.
Innovation Solution
An on-demand fluid jet abrasive recycling system that includes a conveyor and a vacuum positioned adjacent to it, configured to extract foreign materials from the mixture produced by a fluid jet machine, utilizing an initial screen, drying apparatus, and secondary screening assembly with a vacuum to separate foreign particles from abrasive particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional abrasive recycling systems are used, then abrasive material can be recycled, but foreign materials of similar size cannot be effectively differentiated and removed
Solution Approach 1:
The recycling system is divided into multiple independent stages: initial screening, drying, vacuum extraction, and secondary screening. Each stage targets specific foreign materials based on size, moisture content, or density characteristics, enabling progressive separation that overcomes the limitation of single-stage systems
Solution Approach 2:
The system changes physical parameters of the slurry through the process: initial screening separates by size, drying apparatus changes moisture content to concentrate foreign materials, and vacuum extraction uses pressure differential to remove remaining contaminants. These parameter transformations enable differentiation of foreign materials from abrasive particles
2Reliability
If a vacuum is applied to extract foreign materials, then foreign material removal is improved, but system complexity increases
Solution Approach 1:
The vacuum extraction function is segmented into multiple vacuum sources positioned at different locations along the conveyor belt, each handling specific zones. This distributed approach improves removal effectiveness while keeping individual vacuum units manageable in size and complexity
Solution Approach 2:
A conveyor belt serves as an intermediary carrier that transports the slurry through different processing zones. This intermediary allows the vacuum to extract foreign materials without direct contact with the entire slurry volume, simplifying the vacuum system design while maintaining effectiveness

Function Achieved in This Case
The system effectively removes foreign materials from the abrasive slurry, ensuring a cleaner recycled abrasive product by using a combination of screening and vacuum extraction, allowing for adjustable vacuum settings to target specific foreign materials.
Implementation Method 1
a vacuum positioned adjacent to the conveyor, the vacuum configured to extract at least a portion of the foreign material from the mixture
