Gas Trap Quick-Release Coupling for Mud Logging Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas trap devices for mud logging suffer from difficult or impossible access to the agitator shaft and beater bars due to their design, leading to increased maintenance costs and downtime due to wear and breakage from abrasive drilling mud.
Innovation Solution
A gas trap apparatus with a two-part construction featuring a quick-release coupling mechanism that allows rapid detachment of the bottom member from the top member, enabling easy access and replacement of the shaft and beater bars, utilizing a pin and groove arrangement or manually-actuated clips for quick release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gas trap is designed with a unitary construction or tightly secured parts, then structural integrity and sealing are improved, but access to the shaft and beater bars for maintenance becomes difficult or impossible
Solution Approach 1:
The gas trap is divided into multiple separable parts: a top section containing the motor and shaft, and a bottom section containing the beater bars. These sections are connected through a quick-release coupling mechanism that allows them to be easily separated for maintenance while maintaining structural integrity during operation.
Solution Approach 2:
The coupling mechanism transitions from a static, permanently secured design to a dynamic, quickly releasable design. The quick-release coupling allows the connection between top and bottom sections to be rapidly changed from secured to separated state, enabling easy access to internal components while maintaining structural integrity during normal operation.
2Stability of the object's composition
If the gas trap uses traditional secured connections, then structural stability is improved, but maintenance time and downtime increase due to difficulty in accessing components
Solution Approach 1:
The quick-release coupling mechanism is pre-configured with alignment features, interlocking surfaces, and securing elements that are ready for rapid engagement and disengagement. This preliminary preparation of the coupling system eliminates the need for complex assembly procedures during maintenance, significantly reducing maintenance time while ensuring structural stability during operation.
3Ease of manufacture
If the gas trap is designed as a single integrated unit, then manufacturing simplicity is improved, but component replacement and servicing become costly and time-consuming
Solution Approach 1:
The gas trap is segmented into modular sections (top section with motor and shaft, bottom section with beater bars) that can be manufactured separately and then assembled through the quick-release coupling mechanism. This segmentation allows for simplified manufacturing of individual components while enabling easy replacement and servicing of worn parts without requiring complete disassembly or specialized tools.

AI summary
A gas trap apparatus for liberating gas from drilling mud and collecting such gas for analysis. A motor is connected to a rotatable vertical shaft having beater bars thereon, which when the shaft is immersed in drilling mud and rotate, stirs such mud to liberate gas entrained therein. The gas trap is characterized in having a top member and a bottom member which surrounds the vertical shaft and which is releasably secured to the top member thereof by a quick release mechanism which facilitates rapid detachment of the bottom member from the top member to permit quick access said vertical shaft and beater bars thereon for replacement or servicing. The vertical shaft may further likewise be provided with a quick-release means to allow quick release of the shaft from the motor for easy replacement and servicing of same.
