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 their large pores, and often require the strainer to be taken offline for magnet removal, which is not efficient.
Innovation Solution
A pipeline strainer design that includes a drywell for housing magnets, allowing them to be removed without draining liquid from the cavity, and a baffle to minimize particle dispersion, enabling effective collection and removal of magnetic particles without taking the strainer offline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnets are permanently fixed in the pipeline strainer, then magnetic particles are effectively removed from the fluid, but the magnets cannot be easily removed without taking the pipeline strainer offline
Solution Approach 1:
The pipeline strainer is divided into separate functional components: a strainer body, a removable magnet housing, and individual magnets that can be independently removed. This segmentation allows the magnets to be extracted without removing the entire strainer from the pipeline, resolving the contradiction between maintaining magnetic particle removal effectiveness and enabling easy magnet removal for maintenance.
Solution Approach 2:
The magnets are extracted from the permanent structure and placed in a removable housing within the strainer body. This extraction allows the magnets to be taken out independently when needed for maintenance or replacement, while the strainer remains installed in the pipeline, thus maintaining operational ease while preserving magnetic particle removal functionality.
2Ease of repair
If the pipeline strainer is taken offline for magnet removal, then magnets can be properly maintained or replaced, but fluid flow is disrupted and operational time is lost
Solution Approach 1:
The removable magnet housing design segments the magnet assembly from the main strainer body, allowing magnets to be accessed and maintained independently. This enables repair activities to be performed on the magnets without shutting down the entire pipeline system, thus improving ease of repair while minimizing loss of time.
Solution Approach 2:
The design enables continuous operation of the pipeline while allowing intermittent maintenance of the magnets. The magnets can be removed, maintained, or replaced while the strainer remains in place and the pipeline continues to operate, maintaining the continuity of useful action and eliminating unnecessary downtime.
3Productivity
If conventional straining elements with large pores are used, then fluid flow is maintained, but fine metal particles cannot be efficiently removed from the fluid
Solution Approach 1:
The invention merges two different filtration mechanisms: mechanical straining with large pores for bulk debris removal and magnetic attraction for fine metal particle removal. The strainer element handles coarse particles while the magnets capture fine magnetic particles, achieving both high fluid flow rates and effective fine particle removal by combining these complementary mechanisms.
Solution Approach 2:
The pipeline strainer is designed with multi-functionality, serving both as a mechanical strainer for large particles and as a magnetic separator for fine metal particles. This universal design allows a single device to perform multiple removal functions, maintaining productivity while improving reliability of fine particle removal through the added magnetic capture capability.

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. A baffle is disposed at the end of the drywell that is adjacent or near the debris drain to reduce turbulence from the fluid flow within the pipeline strainer.
