Mesh Apparatus for Breaking Magnetic Particle Aggregates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pumps used in analytical testing systems for transferring liquids containing magnetic particles often clog or get damaged due to the formation of aggregates, which impinge on or become caught in the valves, leading to premature wear and maintenance issues.
Innovation Solution
A mesh apparatus is integrated into the liquid transfer system with openings larger than the magnetic particles, disassociating aggregates into smaller particles or individual particles as they pass through, preventing damage to the pumps and ensuring efficient liquid transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pump is used to transfer liquid containing magnetic particles, then liquid transfer is achieved, but the pump valves get clogged and damaged by aggregates
Solution Approach 1:
The mesh apparatus is placed in the liquid transfer path before the pump valves to pre-break up aggregates into smaller particles. This preliminary action prevents the aggregates from reaching and clogging the pump valves, thereby maintaining pump reliability while continuing liquid transfer operations.
Solution Approach 2:
The mesh apparatus acts as an intermediary device between the liquid source and the pump. It intercepts and breaks up aggregates before they can damage the pump valves, serving as a protective mediator that allows continuous liquid transfer without direct contact between aggregates and pump components.
2Productivity
If aggregates of magnetic particles are present in the liquid, then the liquid can be transferred, but the aggregates impinge on and damage the pump valves
Solution Approach 1:
The mesh apparatus performs preliminary breakdown of aggregates before they can reach the pump valves. By intercepting and fragmenting aggregates in advance, the system maintains liquid transfer capability while preventing the harmful impingement of aggregates on valve surfaces.
Solution Approach 2:
The mesh apparatus converts the harmful presence of aggregates into a beneficial filtering effect. The aggregates, which would normally damage the pump, are used to illustrate the mesh's particle breakdown capability, transforming the harmful factor into a demonstration of the protective function.
3Reliability
If a mesh with small openings is used to filter particles, then particle separation is achieved, but the mesh blocks the flow of liquid containing particles
Solution Approach 1:
The mesh openings are designed with specific dimensional parameters that are larger than the magnetic particles but smaller than the aggregates. This parameter optimization allows the mesh to break up aggregates while maintaining adequate flow capacity, balancing particle separation effectiveness with liquid flow rate.

AI summary
An apparatus configured to receive particles in a liquid includes: a housing comprising a housing inlet and a housing outlet; and a mesh located in the housing between the housing inlet and the housing outlet, the mesh having spaces greater than a greatest transverse dimension of the particles. The apparatus operates to break up agglomerates of the particles, such as agglomerates of magnetic particles. Other systems and methods of receiving and transferring liquids containing particles having a propensity to agglomerate are disclosed, as are other aspects.
