Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for separating magnetizable particles from pourable and free-flowing fluids lack the ability to achieve high selectivity and throughput simultaneously, leading to inefficiencies in particle separation and fluid processing.
Innovation Solution
A device with a pressure-tight fluid chamber and a magnet arrangement comprising multiple magnet coils, which can rotate relative to the housing, separated from the fluid chamber by a non-magnetic sleeve, allows for high selectivity in particle separation. The magnet arrangement is designed to maximize the magnetic field's depth effect and contact surface with the fluid, while a guide helix and removal magnet system facilitate efficient particle collection and fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a magnet arrangement is used to separate magnetizable particles from fluid, then separation selectivity is improved, but fluid throughput is reduced
Solution Approach 1:
The magnet arrangement is divided into multiple magnet coils arranged in segments around the fluid chamber. Each coil can be independently controlled and optimized for specific separation tasks, allowing simultaneous maintenance of high magnetic field strength for selectivity and distributed configuration for reduced flow resistance
Solution Approach 2:
The magnet coils are designed to be rotatable relative to the housing, creating a dynamic magnetic field configuration. This allows the system to adjust between different operational modes: high-field configurations for maximum separation selectivity and lower-field configurations optimized for higher fluid throughput, resolving the contradiction between the two parameters
2Reliability
If the magnet arrangement is separated from the fluid chamber by a sleeve, then particle contamination of magnets is prevented, but magnetic field strength is reduced
Solution Approach 1:
A thin-walled non-magnetic sleeve is positioned between the magnet arrangement and fluid chamber. The sleeve material and wall thickness are specifically selected to provide adequate contamination protection while minimizing magnetic field attenuation, thus balancing reliability improvement with acceptable magnetic force reduction
Solution Approach 2:
The sleeve is constructed from composite materials with optimized magnetic permeability properties. These materials allow the magnetic field to pass through with minimal reduction while maintaining the protective barrier function, effectively resolving the contradiction between contamination prevention and magnetic field strength
3Measurement precision
If multiple magnet coils are used to increase magnetic field coverage, then separation effectiveness is improved, but device complexity increases
Solution Approach 1:
The multiple magnet coils are designed with universal functionality, where each coil can serve multiple purposes: particle separation, field calibration, and diagnostic functions. This multi-functionality justifies the increased complexity by providing enhanced separation effectiveness alongside additional operational capabilities
Solution Approach 2:
The magnet coils operate in periodic sequences rather than continuously, with coordinated activation patterns that reduce overall system complexity. By cycling through different coil configurations periodically, the system achieves comprehensive particle separation while simplifying control logic and reducing simultaneous operational demands
