Solution Overview
Problem
Current vibrating screen separators in the oilfield drilling process face inefficiencies due to the need for multiple component parts to control vibration patterns, deck angles, and motion, which leads to fatigue and reduced performance over time.
Innovation Solution
The use of linear motors, specifically tubular and flat linear motors, to impart vibrational motion to a movable basket within a screen separator, allowing for controlled and adjustable vibrational patterns, including linear and elliptical motions, to enhance separation efficiency and reduce component wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple component parts are used to control vibration patterns, deck angles, and motion in traditional vibratory screen separators, then separation functionality is achieved, but component wear and fatigue increase, reducing reliability and increasing maintenance
Solution Approach 1:
The patent merges multiple control functions (vibration pattern control, deck angle adjustment, motion control) into a single linear motor system. The linear motor replaces traditional separate mechanisms for vibration excitation, angle adjustment, and motion control, consolidating multiple component parts into one integrated actuator that reduces component wear and simplifies the overall system structure while maintaining full separation functionality
Solution Approach 2:
The linear motor serves multiple functions simultaneously: it generates vibrational motion, controls deck angle, and regulates material flow across the screen. This multi-functional approach eliminates the need for separate dedicated components for each control aspect, thereby reducing the total number of parts subject to wear and fatigue while achieving comprehensive separation control
2Ease of operation
If traditional vibratory mechanisms with multiple components are used, then vibration control is achieved, but maintenance requirements increase due to component fatigue
Solution Approach 1:
By combining vibration generation, angle control, and motion regulation into a single linear motor system, the patent reduces the number of components that require maintenance. The integrated design eliminates multiple moving parts that would otherwise be subject to fatigue and wear, significantly reducing maintenance frequency while preserving full vibration control capability through electronic regulation of the linear motor
3Productivity
If adjustable vibration patterns are implemented using multiple components, then separation efficiency improves, but device complexity and component wear increase
Solution Approach 1:
The linear motor provides universal control over all vibration parameters (amplitude, frequency, pattern, deck angle) through a single actuator. This multi-functional capability enables adjustable vibration patterns for optimized separation efficiency without requiring multiple separate control components, thereby improving productivity while avoiding the component proliferation and associated wear that would result from traditional multi-component control systems
