Cyclonic Separator Layout to Prevent Vortex Finder Hair Wrap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners face issues with debris, particularly fibrous materials like hair, wrapping around vortex finders, leading to blockages and reduced performance, as existing designs often require arrestor plates that can cause obstructions.
Innovation Solution
A cyclonic separator with first and second vortex finders extending from opposing sides of a chamber, spaced apart to prevent debris wrapping, and configured to operate in series or parallel, eliminating the need for an arrestor plate, enhancing separation efficiency and reducing filter cleaning frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an arrestor plate is used to prevent debris wrapping around vortex finders, then debris blockage is reduced, but device complexity increases and separation efficiency decreases
Solution Approach 1:
The patent removes the arrestor plate component entirely from the cyclonic separator design. Instead of adding an arrestor plate to prevent debris wrapping, the invention uses a different approach by positioning the vortex finder at a specific distance from the cyclone chamber wall, allowing debris to naturally fall to the bottom without requiring an additional structural component.
Solution Approach 2:
The patent introduces an intermediary space between the vortex finder and the cyclone chamber wall. This gap acts as a mediator that allows air to flow smoothly while preventing debris from wrapping around the vortex finder, eliminating the need for a solid arrestor plate structure.
2Reliability
If an arrestor plate is installed in the cyclonic separator, then fibrous debris wrapping is prevented, but separation efficiency is reduced
Solution Approach 1:
The patent extracts the arrestor plate from the system and replaces it with a geometric solution. The vortex finder is positioned at a specific distance from the cyclone chamber wall, creating a natural barrier against fibrous debris wrapping without interfering with the cyclonic flow pattern that drives separation efficiency.
Solution Approach 2:
The patent changes the geometric parameters of the cyclonic separator, specifically the distance between the vortex finder and the cyclone chamber wall. By optimizing this distance parameter, the design prevents fibrous debris wrapping while maintaining strong cyclonic rotation and high separation efficiency.
3Device complexity
If vortex finders are positioned close together, then device complexity is reduced, but debris wrapping and blockages increase
Solution Approach 1:
The patent applies local quality by creating a specific spatial relationship between the vortex finder and the cyclone chamber wall. The distance parameter is optimized locally at the vortex finder position to prevent debris wrapping, while the rest of the cyclone chamber maintains its standard structure for efficient separation.
