Pipeline Strainer Magnetic Insert for Online Fine Particle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipeline strainers are unable to efficiently remove fine metal particles, such as iron oxides, from fluids due to large pore sizes, and often require the strainer to be taken offline for magnet removal, which is not efficient.
Innovation Solution
A pipeline strainer design featuring a drywell that allows magnets to be removed without draining liquid from the cavity, using a Y-shaped body with a straining element and a debris drain system that collects metal particles on the outer surface of the drywell for easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnets are installed in the pipeline strainer to remove fine metal particles, then particle removal effectiveness is improved, but the complexity of magnet removal and maintenance increases
Solution Approach 1:
The pipeline strainer is divided into separate functional components: a straining element for mechanical filtration and a removable magnet assembly for magnetic particle removal. This segmentation allows the magnet to be independently removed and replaced without affecting the overall strainer structure or requiring system shutdown.
Solution Approach 2:
The magnet is designed as a separate, extractable component that can be removed from the pipeline strainer without taking the entire device offline. The magnet assembly includes a magnet holder that can be detached, allowing easy extraction and replacement of the magnet while the strainer remains in service.
2Ease of operation
If conventional straining elements with large pores are used, then ease of operation is maintained, but fine metal particles cannot be efficiently removed
Solution Approach 1:
The invention combines two different filtration mechanisms into a single pipeline strainer system: mechanical filtration through the straining element and magnetic attraction through the magnet assembly. This merging allows both large particles (caught by the straining element) and fine metal particles (attracted by the magnet) to be removed simultaneously, maintaining operational simplicity while improving particle removal efficiency.
Solution Approach 2:
Different regions of the pipeline strainer have different functional properties: the straining element provides mechanical filtration with larger openings for general particle removal, while the magnet assembly provides localized magnetic attraction for fine metal particles. This local differentiation of functional qualities allows each component to optimize its specific removal mechanism.
3Ease of repair
If magnets are removed from the pipeline strainer, then maintenance is simplified, but the strainer must be taken offline causing loss of time
Solution Approach 1:
The magnet assembly is pre-configured with a magnet holder and retrieval mechanism that enables quick removal and replacement. The design anticipates maintenance needs by providing a ready-to-install magnet assembly that can be quickly swapped without requiring complex disassembly or system shutdown procedures.

AI summary
A pipeline strainer having a body with a straining element therein. One or more magnets are removably inserted into the straining element and configured to be removed from the body without causing liquid within the cavity to drain from the pipeline strainer. A drywell is used to house the magnets. The movement of withdrawing the magnets pulls metal particles along the outer surface of the drywell toward a debris drain.
