Circulation Pump in Drilling Mud Flushing Tank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drilling mud processing devices require frequent maintenance due to the accumulation of large solids in the first compartment of the flushing fluid storage tank, which hampers efficient operation and reuse of drilling fluid.
Innovation Solution
Incorporating a circulation pump within the flushing fluid storage tank to maintain a continuous water flow, preventing the settling of solids and reducing the need for maintenance by keeping them in motion, thereby enhancing the system's simplicity and extending maintenance intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a partition with openings is used to separate compartments in the flushing fluid storage tank, then larger solids are retained in the first compartment, but solids accumulate in the first compartment requiring frequent maintenance
Solution Approach 1:
The patent introduces a circulation pump that creates dynamic water flow within the first compartment, transforming the static sedimentation process into a dynamic circulation system. The pump draws water from the bottom of the first compartment and discharges it near the top, creating continuous movement that prevents solids from accumulating in thick layers and maintains operational efficiency for extended periods
Solution Approach 2:
The circulation pump operates continuously or periodically to maintain water movement in the first compartment, ensuring that the separation function remains effective over long periods. This continuous action prevents the degradation of separation efficiency that would occur with static compartments, thereby extending maintenance intervals while maintaining reliable drilling fluid reuse
2Reliability
If the flushing fluid storage tank is designed with multiple compartments, then separation of solids by size is improved, but the device complexity increases
Solution Approach 1:
The storage tank is divided into multiple compartments (first and second compartments) separated by a partition with openings. This segmentation allows different sizes of solids to be retained in different compartments, with larger solids in the first compartment and smaller solids in the second compartment, thereby improving overall separation efficiency while maintaining a relatively simple tank structure
Solution Approach 2:
The partition wall serves multiple functions: it physically separates the two compartments for size-based separation, allows water to pass through via openings for circulation, and guides the flow pattern within the tank. This multi-functionality reduces the need for additional components while achieving effective solids separation
