Cyclonic Separator Outlet Duct Layout for Compact Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclonic separators are bulky due to the unutilized central space around the cyclone bodies, which hinders the reduction of size without compromising performance.
Innovation Solution
The cyclonic separator design incorporates an outlet duct that extends between two adjacent cyclone bodies, utilizing the central space to discharge cleansed fluid and incorporating an elongated filter to prevent collapse, thereby eliminating the need for a manifold and reducing the overall size while maintaining performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional manifold structure is used to collect fluid from cyclone bodies, then fluid collection is effective, but the separator height increases and compactness is reduced
Solution Approach 1:
The outlet duct is merged with the separator housing structure, eliminating the need for a separate manifold. The outlet duct extends between adjacent cyclone bodies and integrates the fluid collection function directly into the separator body, reducing overall height and improving compactness while maintaining effective fluid collection from all cyclone bodies.
2Volume of moving object
If the central space around cyclone bodies is left unutilized, then cyclone body arrangement is simple, but separator size increases
Solution Approach 1:
The outlet duct is nested within the central space that surrounds the cyclone bodies. The first section of the outlet duct extends along the axis about which the cyclone bodies are arranged, utilizing the previously wasted central volume. This nesting approach reduces the overall separator size without complicating the cyclone body arrangement.
3Loss of substance
If a hollow tube filter is used without support structure, then material usage is reduced, but the filter may collapse under pressure
Solution Approach 1:
The hollow tube filter is inflated by the fluid pressure from the cyclone bodies themselves. The fluid entering the interior of the filter through the open end creates internal pressure that expands the flexible hollow tube, maintaining its shape and structural integrity without requiring any external support framework. This pneumatic support eliminates material usage while preserving filter strength.
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
This design results in a more compact and cost-effective cyclonic separator with improved separation efficiency and reduced material usage, allowing for a lower center of gravity in vacuum cleaners, enhancing stability and maneuverability.
Implementation Method 1
Vacuum cleaners having a cyclonic separator are now well known
Implementation Method 2
dirt that has not been separated from the fluid by the cyclone bodies
Implementation Method 3
Dirt that has not been separated from the fluid by the cyclone bodies may then be removed by the filter
Implementation Method 4
fluid from the cyclone bodies enters the interior of the filter via the open end and passes through the filter into the outlet duct. As a result, the fluid acts to inflate the filter and thus prevent the filter from collapsing
