Lead-Edge Ramp Screen Assembly for Shaker Clamp Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sifting screens used in the oil and gas industry for removing drilling debris from synthetic muds face issues with mesh wear and tear due to vibration, leading to reduced operational life and increased replacement frequency, which affects drilling efficiency and costs.
Innovation Solution
A screen assembly with a leading edge ramp and clamping surface that facilitates easy installation and engagement with a shaker system, combined with a trailing edge latch for alignment and secure attachment, enhancing the longevity and efficiency of the screen assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the screen is divided into multiple cells to extend operational life, then the reliability improves, but the device complexity increases
Solution Approach 1:
The screen is divided into multiple rectangular cells or openings, allowing individual mesh sections to be isolated. When mesh failure occurs in one cell, that specific cell can be blocked off while the remainder of the screen continues to function, thereby extending the overall operational life of the screen assembly.
2Productivity
If the screen weight and exposed mesh area are increased to improve mud recovery capacity, then the productivity improves, but the stress on the screen structure increases
Solution Approach 1:
The screen frame is divided into multiple cells that can independently support portions of the mesh and processing load. This segmentation distributes the stress across multiple structural nodes rather than concentrating it on a single continuous mesh structure, allowing for increased overall screen area and weight without proportionally increasing structural stress.

AI summary
Systems and methods including a screen assembly with a screen frame configured to couple to a screen filter. The screen frame includes a leading edge with a ramp to facilitate sliding the screen frame relative to a clamp of a shaker system. The leading edge may contain an engagement surface and/or mechanism that can help facilitate the clamping of the screen within the shaker system as well as allow for one screen to be engaged with another screen.
