Vibrating Sieve Filters for Linear Object Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sorting electronic/electrical equipment component waste struggle with efficiently separating linear objects like wire scraps from mixed waste, leading to entanglement and reduced separation accuracy, and the presence of refining inhibitors like Sb can affect blast furnace operations.
Innovation Solution
A vibrating sieve machine with a specific configuration of filters and a guide is used to sieve and separate linear objects from plate-form objects, where filters are arranged to partially overlap and have free ends, and a guide is placed below the downstream filter to capture lumpy objects, improving separation efficiency and preventing refining inhibitors from entering the blast furnace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sorting methods are used for separating linear objects from mixed waste, then the sorting process can be performed, but the linear objects become entangled and separation accuracy deteriorates
Solution Approach 1:
The patent employs a vibrating sieve machine that generates vibrations to prevent linear objects from becoming entangled during the sorting process. The vibration causes the linear objects to move and separate more effectively, reducing entanglement issues and improving separation accuracy while maintaining reliable operation
Solution Approach 2:
The patent divides the sorting process into distinct stages using multiple sieves with different mesh sizes arranged in sequence. This segmentation allows for progressive separation of linear objects from mixed waste, with each sieve handling a specific size range, thereby improving overall separation accuracy while preventing entanglement through staged processing
2Productivity
If linear objects are not properly separated before blast furnace processing, then the processing can proceed, but refining inhibitors contaminate the blast furnace and decrease processing efficiency
Solution Approach 1:
The patent performs preliminary separation of linear objects containing refining inhibitors before the waste material enters the blast furnace. By using the vibrating sieve machine to remove these linear objects in advance, the harmful refining inhibitors are prevented from contaminating the blast furnace, thereby maintaining high processing efficiency and avoiding operational disruptions
