Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sorting devices for recovering coins from bulk materials, such as waste incineration slag, are complex, require significant space and labor, and incur high maintenance costs due to aggressive and abrasive properties of the materials, leading to inefficient and costly coin recovery.
Innovation Solution
A sorting device with a discharge hood and trajectory separator device that integrates a roller system to guide non-ferrous metal fractions into a sorting gap, reducing the need for high material throughput and allowing for multi-stage sorting without additional processing steps, using rollers and baffle plates to separate and sort coins efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sorting devices are used to recover coins from bulk material, then coin recovery can be achieved, but device complexity and space requirements increase significantly
Solution Approach 1:
The patent combines the sorting device with the discharge hood of an eddy current separating device, integrating two functions into one structure. The discharge hood serves both as the containment structure for the eddy current separator and as the housing for the roller sorting mechanism, eliminating the need for separate sorting device housing and reducing overall system complexity.
Solution Approach 2:
The discharge hood is designed to serve multiple functions: it contains the eddy current separating device, provides structural support for the roller sorting mechanism, and acts as the discharge structure for separated materials. This multi-functionality reduces the number of separate components needed and simplifies the overall system.
2Productivity
If traditional sorting devices process large material throughputs, then coin recovery efficiency improves, but maintenance costs increase due to abrasive properties of bulk material
Solution Approach 1:
The patent extracts the sorting function from the main bulk material flow path by using a roller mechanism that selectively engages with non-ferrous metal objects. The roller applies localized force only to objects that need sorting, rather than processing the entire bulk material stream, thereby reducing wear on sorting components while maintaining throughput efficiency.
Solution Approach 2:
The patent replaces traditional mechanical sorting mechanisms with a roller-based system that uses rotational force and gravity. The roller rotates to apply centrifugal force and guide non-ferrous metal objects into the sorting gap, reducing mechanical contact and wear compared to traditional conveyor-based sorting systems.
3Manufacturing precision
If multiple processing steps are used for coin recovery, then sorting quality improves, but space requirements and labor needs increase
Solution Approach 1:
The patent segments the sorting process into distinct functional zones within the discharge hood: an eddy current separation zone for initial metal separation, a roller sorting zone for non-ferrous metal object separation, and a coin collection zone. This segmentation allows multiple sorting stages to be performed in a compact, integrated manner rather than requiring separate processing steps.
Solution Approach 2:
The sorting device is nested within the discharge hood structure, with the roller sorting mechanism positioned inside the discharge hood volume. The coin collection container is also nested within the discharge hood, allowing multiple functions and storage spaces to be contained within a single compact structure.
