Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing classified landfill devices require shutdown to treat metals absorbed by magnets, as the adsorption force decreases when the magnet surface is saturated, leading to metal accumulation issues.
Innovation Solution
A classified landfill device with a disposal box equipped with a screening mechanism, crushing mechanism, and discharge mechanism, where the magnet is integrated with a drive belt system that slows down garbage flow, allowing metal accumulation and subsequent collection without shutting down the device, and angled crushing knives to prevent garbage accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the magnet absorbs metals in the garbage continuously, then the metal separation efficiency is improved, but the adsorption force decreases when the magnet surface is saturated
Solution Approach 1:
The magnet is divided into multiple segments arranged in a circular pattern, allowing different regions of the magnet to perform absorption at different stages. This segmentation enables continuous operation without saturation of any single magnet surface.
Solution Approach 2:
The magnet rotates together with the conveying belt, dynamically changing the position of metal-rich and metal-poor regions. This dynamic movement allows continuous exposure of fresh magnet surfaces to garbage while maintaining consistent separation efficiency.
2Productivity
If the device operates continuously without shutdown, then the operational efficiency is improved, but the metal accumulation on magnet surface increases
Solution Approach 1:
The magnet is segmented into multiple sections that rotate with the conveying belt, distributing metal accumulation across different segments. This allows continuous operation while preventing any single segment from becoming overly saturated.
Solution Approach 2:
The rotating magnet dynamically redistributes accumulated metal across different surfaces, preventing localized saturation and enabling continuous operation without shutdown for metal removal.
3Productivity
If the conveying speed is increased, then the processing capacity is improved, but the metal absorption time is reduced
Solution Approach 1:
The magnet rotates at the same speed as the conveying belt, creating a dynamic interaction that extends the effective absorption time. The rotation allows multiple passes of garbage over different magnet surfaces, maintaining absorption efficiency despite high conveying speed.
Solution Approach 2:
Multiple magnet segments are distributed along the conveying path, allowing garbage to interact with multiple magnet surfaces sequentially. This extends the total absorption time without increasing the conveying speed.
