Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulk blending systems for cement powders in oilfield drilling face issues with inconsistent mixing, contamination, and dust emissions, leading to potential failures in cementing processes that can result in costly delays, environmental damage, and safety risks.
Innovation Solution
The implementation of a tumble blender system with a slant cone design, pneumatically operated, and coupled conduits to ensure sealed material transfer, reducing contamination risks and dust emissions, and providing a reliable method for blending cement ingredients and additives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pneumatic blenders are used for cement powder blending, then material transfer can be achieved, but inconsistent mixing and contamination occur
Solution Approach 1:
The patent removes the traditional pneumatic blender from the system and replaces it with a tumble blender. This extraction of the problematic blending mechanism eliminates the sources of inconsistent mixing and contamination while maintaining the material transfer function through alternative means.
Solution Approach 2:
The patent replaces the pneumatic blending system with a mechanical tumble blending system. The tumble blender uses mechanical rotation to achieve consistent mixing without the contamination issues associated with pneumatic systems, thereby improving reliability while reducing harmful factors.
2Productivity
If conventional blending systems are used, then material processing can be performed, but dust emissions increase
Solution Approach 1:
The patent employs sealed conduits with flexible coupling mechanisms that create dust-tight seals during material transfer. This encapsulation of the material flow path prevents dust emissions while maintaining efficient material processing, resolving the contradiction between productivity and harmful emissions.
3Ease of manufacture
If cement blending is performed at bulk plants, then material preparation can be done, but costly failures and delays may occur
Solution Approach 1:
The patent creates a replicated, optimized blending system at each bulk plant location that can independently produce consistent cement blends. This local replication of the proven tumble blender system ensures reliable material preparation without the risks associated with traditional systems, eliminating the need for costly remediation.
