Solution Overview
Problem
Existing separation methods for substance mixtures, such as slag, flue ash, and waste garbage, are complex, costly, and prone to equipment failure, especially when dealing with sticky mixtures.
Innovation Solution
A rotating drum apparatus that comminutes, homogenizes, and separates substance mixtures based on density by accelerating particles with striking tools and centrifugal forces, allowing for adjustable conveying elements and collection apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple screens and baths are used for separation, then separation completeness is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines comminution, homogenization, and separation functions into a single rotating drum apparatus. The drum performs all separation operations in one device rather than requiring multiple separate screens and baths, thereby reducing device complexity while maintaining separation effectiveness through the combined action of impact comminution and centrifugal separation.
Solution Approach 2:
The rotating drum serves multiple functions simultaneously: it acts as a comminution device through impact, a homogenizer through continuous mixing, and a separation device through centrifugal forces. This multi-functionality eliminates the need for separate dedicated equipment for each operation, simplifying the overall system while achieving complete separation.
2Manufacturing precision
If multiple screens and baths are used for separation, then separation completeness is improved, but operational cost increases
Solution Approach 1:
By merging comminution and separation into one apparatus, the patent eliminates the need for multiple separate equipment units, reducing capital investment and operational costs associated with maintaining and operating multiple devices while achieving the same separation completeness.
Solution Approach 2:
The rotating drum apparatus performs self-comminution through impact, eliminating the need for separate comminution equipment and the associated operational costs. The system uses its own rotation and the impact of material against the drum surface to achieve both size reduction and separation in a self-sufficient manner.
3Ease of operation
If conventional separation methods are used, then separation capability is provided, but reliability decreases due to equipment failure
Solution Approach 1:
The drum surface acts as a replaceable working element that can be easily replaced when worn or damaged. This approach improves reliability by allowing quick replacement of the consumable drum surface rather than replacing entire complex separation systems, minimizing downtime and maintaining continuous separation capability.
4Ease of operation
If conventional separation methods are used, then separation capability is provided, but cleaning effort increases substantially
Solution Approach 1:
The patent extracts the separation process from complex multi-component systems and concentrates it into a single rotating drum with a removable surface. This simplification allows the entire separation zone to be easily accessed and cleaned by simply removing the drum surface, dramatically reducing cleaning effort compared to disassembling and cleaning multiple screens and baths.
