Flexible Metal Separator with Movable Outlet for Plastic Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal separator devices in the plastics processing industry face issues such as jamming, contamination, and high maintenance due to complex structures and multiple parts, which hinder efficient separation of metal-containing particles from flowing materials, especially in cases of non-free-flowing materials and standing columns.
Innovation Solution
A flexible, one-piece conveyor line made of non-metallic material with a built-in metal separator that detects metal particles and adjusts its outlet to divert the flow into different channels, eliminating the need for separate diverters and reducing dead volumes, while using magnets to accumulate ferromagnetic particles for enhanced separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate diverter is used to separate metal-containing particles from conveyed material, then the separation function is achieved, but the device complexity increases and maintenance requirements increase
Solution Approach 1:
The patent combines the conveyor line and diverter into a single integrated component. The conveyor line itself is designed with a movable outlet that can be positioned in different channels, eliminating the need for a separate diverter device. This merging reduces device complexity while maintaining the separation function.
Solution Approach 2:
The conveyor line is designed to perform multiple functions: it conveys material and simultaneously acts as the diverting mechanism through its movable outlet. This multi-functionality eliminates the need for separate components, reducing overall device complexity while achieving the separation objective.
2Reliability
If a separate diverter is used for separation, then metal particle separation is achieved, but maintenance requirements and operational issues increase
Solution Approach 1:
By integrating the diverter function into the conveyor line, the number of separate components that require maintenance is reduced. The conveyor line's movable outlet serves as the diverting mechanism, eliminating wear and maintenance issues associated with separate diverter components.
3Reliability
If multiple separate components are used for separation, then separation capability is achieved, but dead volumes and contamination risks increase
Solution Approach 1:
The integration of the conveyor line and diverter eliminates gaps and dead volumes that would exist between separate components. The continuous design of the integrated system prevents material accumulation in intermediate spaces, reducing contamination risks and substance loss.
4Reliability
If a complex multi-component system is used for separation, then separation function is achieved, but operational smoothness and flow continuity are compromised
Solution Approach 1:
The integrated design allows for smoother operation as there are no interfaces or gaps between separate components. The movable outlet of the conveyor line can transition between channels without the operational issues that arise from coordinating multiple separate components, maintaining flow continuity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides efficient and cost-effective metal particle separation with reduced maintenance, improved flow continuity, and effective handling of non-free-flowing materials, along with enhanced magnetic particle detection and collection, minimizing contamination and material waste.
Implementation Method 1
The metal separator essentially consists of an induction coil that surrounds the conveying pipe. The metal parts carried along in the conveying flow change the inductance of the induction coil, which leads to an output signal that can be evaluated at the induction coil.
Implementation Method 2
using magnets to accumulate ferromagnetic particles for enhanced separation

AI summary
The device (14) has multiple magnets (34) extending toward a pipeline transporting a material to be conveyed. Poles of the magnets are radially and alternately provided around the pipeline. The device is arranged around the pipeline and opened at a point by a joint and/or a hinge. The device consists of two separated halves interconnected for completely retaining the pipeline, where a pressure line consists of an electrically non-conducting material and/or a hose/pipe. The pressure line is formed from a non-metallic flexible material, and includes an inlet and a discharge opening.
