Hydrocyclone Internal Edges for Complete Particle Stratification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydrocyclones often fail to achieve complete stratification of particulate material, leading to incomplete classification due to particles becoming stuck together or trapped against the walls, resulting in incorrect separation based on shape, size, and specific gravity.
Innovation Solution
Incorporating internal edges or grooves within the hydrocyclone that disturb the flow of material, creating a smooth transition in diameter and pressure variation to dislodge particles from each other and re-mix them for improved stratification, using a conically tapered separation part with varying diameters and potentially a hose segment for durability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If particles are allowed to settle and stratify in the hydrocyclone, then classification based on shape, size and specific gravity is achieved, but particles become stuck together or trapped against the walls causing incomplete separation
Solution Approach 1:
The patent applies periodic action by creating alternating zones of high and low pressure through the conical geometry and internal edges. This periodic pressure variation prevents particles from becoming trapped against the walls by periodically disrupting the stratification, allowing continuous re-mixing and re-stratification cycles that improve overall classification completeness
Solution Approach 2:
The patent changes physical parameters by varying the pressure gradient and flow velocity through the conical section. The changing diameter creates varying pressure conditions that prevent particle adhesion to walls and promote continuous movement through the classification zone, thereby improving stratification reliability
2Productivity
If the hydrocyclone operates with high velocity flow to improve separation speed, then productivity increases, but particles become trapped against the walls and stratification becomes incomplete
Solution Approach 1:
The patent applies local quality by creating different flow conditions in different zones of the hydrocyclone. The conical section and internal edges create localized high-turbulence zones that prevent wall adhesion, while other zones maintain the velocity and pressure conditions necessary for rapid separation, thus achieving both high productivity and accurate classification
3Manufacturing precision
If particles are forced away from the wall to re-mix with adjacent flow, then stratification is improved and classification quality increases, but the process complexity increases due to additional flow disturbances
Solution Approach 1:
The patent applies segmentation by dividing the flow path into distinct zones using internal edges and the conical geometry. This segmentation creates discrete regions where particles are alternately forced toward the wall and then re-mixed, achieving improved stratification through a series of simple geometric features rather than a complex active control system
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
Enhances the stratification process by allowing particles to assume their correct positions, improving classification quality and efficiency by ensuring proper separation based on shape, size, and specific gravity.
Implementation Method 1
The slurry is typically fed tangentially or in a volute path to the outer wall of the top portion, thus creating a whirling stream of the slurry
Implementation Method 2
The pressure will be lower along the central axis of the vortex and increase radially outwardly towards the outer wall of the hydrocyclone
Implementation Method 3
The hydrocyclone will separate the particles of the slurry according to shape, size and specific gravity with faster settling particles moving towards the outer wall
