Multi-Stage Cyclone Layout for Compact Fine Dust Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclone dust separating apparatuses for vacuum cleaners are inefficient in separating fine contaminants due to their limited design, which often requires multiple stages and increased complexity, making them bulky and ineffective for handling various particle sizes.
Innovation Solution
A multi-stage cyclone dust separating apparatus with a first cyclone chamber for initial separation, followed by one or more second and third cyclone chambers arranged along the outer boundary of the first, each utilizing centrifugal force to enhance contaminant separation efficiency while maintaining a compact size, with the third cyclone chambers being smaller and arranged in a mirror-symmetrical configuration.

Engineering Contradiction Analysis
1Productivity
If multiple cyclone chambers are used to improve contaminant separation efficiency, then cleaning efficiency is improved, but the overall size and structural complexity of the apparatus is enlarged
Solution Approach 1:
The patent applies nesting by placing second and third cyclone chambers inside or along the outer boundary of the first cyclone chamber. The second cyclone chambers are positioned within the space defined by the first chamber's outer boundary, and third cyclone chambers are arranged within the space defined by the second chambers' outer boundaries. This nested configuration allows multiple separation stages to coexist in a compact arrangement, improving contaminant separation efficiency while avoiding proportional increases in overall apparatus size and structural complexity.
Solution Approach 2:
The patent transitions from a single linear arrangement of cyclone chambers to a multi-dimensional nested configuration. Instead of simply adding chambers in sequence along one dimension, the invention utilizes radial and concentric arrangements where chambers are positioned in different spatial dimensions - the second chambers are arranged along the outer boundary of the first, and third chambers are arranged along the outer boundary of the second chambers. This dimensional reorganization enables efficient use of internal space, achieving enhanced separation capability without linearly increasing the apparatus footprint.

If a single cyclone chamber is used, then the apparatus remains compact, but contaminant separation efficiency is limited
Solution Approach 1:
The patent applies segmentation by dividing the contaminant separation process into multiple distinct stages, each handled by a separate cyclone chamber type. The first cyclone chamber performs initial separation, the second cyclone chambers perform intermediate separation, and the third cyclone chambers perform final separation of fine contaminants. This segmentation of the separation function across multiple specialized chambers enables comprehensive contaminant removal while maintaining a compact overall structure through efficient spatial arrangement.
Solution Approach 2:
The patent applies nesting by placing second and third cyclone chambers inside or along the outer boundary of the first cyclone chamber. The second cyclone chambers are positioned within the space defined by the first chamber's outer boundary, and third cyclone chambers are arranged within the space defined by the second chambers' outer boundaries. This nested configuration allows multiple separation stages to coexist in a compact arrangement, improving contaminant separation efficiency while avoiding proportional increases in overall apparatus size and structural complexity.

AI summary
A cyclone dust separating apparatus has a first cyclone chamber for separating particles from the externally-drawn fluid by centrifugal force, one or more second cyclone chambers for separating particles from the fluid discharged from the first cyclone chamber by centrifugal force, and one or more third cyclone chambers for separating particles from the fluid discharged from the second cyclone chambers, and causing the fluid to be discharged out via a discharge passage. The second and the third cyclone chambers are arranged in radial relation with respect to the first cyclone chamber, and thus, surround the first cyclone chamber. Therefore, the cyclone dust separating apparatus provides multi-stage centrifugal cleaning process and improved cleaning efficiency, while remaining compact-sized.
