Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional centrifugal separators are limited by their inflexibility in handling different types of drilling fluids, require laborious maintenance, result in wet discharge, and suffer from solid phase accumulation blocking the discharge, leading to inefficiencies and operational interruptions.
Innovation Solution
A centrifugal separator with adjustable separation nets and a cylindrical drum design, featuring a rotatable annular screw feeder and a cleaning system, allows for flexible operation, rapid maintenance, and effective separation of liquid and solid phases, enabling efficient handling of various drilling fluids and reducing maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional centrifugal separators with frustum-shaped drums and screw removers are used, then solid phase separation is achieved, but the discharge becomes blocked by accumulated solid phase requiring operator intervention
Solution Approach 1:
The patent applies a vibrating unit that generates vibrations in the solid phase at the discharge end, causing the solids to move along the drum surface and preventing accumulation and blocking. This mechanical vibration resolves the contradiction by maintaining continuous operation without operator intervention while keeping the discharge clear.
2Productivity
If conventional centrifugal separators are used, then separation of liquid and solid phases is achieved, but maintenance and cleaning require continuous laborious work causing operational interruptions
Solution Approach 1:
The patent implements a cleaning system with nozzles that automatically clean the separation nets during operation, and a vibrating unit that prevents solid phase accumulation. These self-service mechanisms reduce the need for manual maintenance and cleaning, thereby maintaining operational continuity without laborious interventions.
3Adaptability or versatility
If conventional centrifugal separators with horizontal axis drums are used, then drilling muds can be stratified and discharged, but the system lacks flexibility for treating different types of fluids
Solution Approach 1:
The patent employs adjustable separation nets that can be repositioned radially and inclined at different angles, allowing the system to adapt to different fluid types and separation requirements. This dynamic adjustability provides versatility without requiring complex drum redesigns, as the same drum structure can accommodate various net configurations.
4Productivity
If conventional centrifugal separators are used, then solid phase is separated from liquid phase, but the discharge remains relatively wet requiring additional drying processes
Solution Approach 1:
The vibrating unit agitates the solid phase at the discharge end, enhancing the separation efficiency and allowing for drier discharge by preventing liquid phase adherence to the solids. This mechanical action improves separation effectiveness and reduces moisture content in the discharged solid phase.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The centrifugal separator achieves high performance in separating liquid and solid phases, simplifies maintenance, and allows for flexible treatment of diverse drilling fluids, enhancing the 'solids control' process while preventing solid phase accumulation and maintaining consistent centrifugal force across the drum.
Implementation Method 1
By virtue of the centrifugal force, the drilling muds are stratified: the solid phase is arranged on the furthest outward annulus inside the rotatable drum
Implementation Method 2
separation nets (100), also called screens, arranged in the wall (50) of the rotatable drum (5), which have meshes for filtering the solid phase of the mixture of substances from the liquid phase, by rotation of the rotatable drum (5)
Implementation Method 3
a vibrating unit (300) for agitating the solid phase, which may comprise a half-drum (302), for shaking out the solid phase at its point of exit from the rotatable drum (5)
