Cyclone Filter Bypass Path Design to Prevent Filament Clogging

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional air cyclone separation and filtration systems are inadequate in handling filament-like particles, such as hair or string-like materials, due to their aspect ratio and tendency to agglomerate, leading to clogging and degradation of the flow field, especially when the length of filaments approaches the cyclone dimensions.

Innovation Solution

The cyclone separation system incorporates a crossflow filter with a bypass opening and a return path, which directs agglomerated filament particles away from the main airflow path into a debris bin, preventing clogging and maintaining flow efficiency by balancing pressure drops and utilizing a crossflow filter with a design that prevents filament entrapment.

Engineering Contradictions & Design Principles

1Reliability

If conventional cyclone separation systems are used, then spherical particles can be effectively separated, but filament-like particles cause clogging and flow field degradation

Engineering Contradiction:

Improveseparation effectivenessVSAvoidclogging

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cyclone system is divided into multiple functional zones: a separation chamber for spherical particles, a bypass passage for filaments, and a collection chamber. This segmentation allows different particle types to be handled through different paths, preventing filament clogging while maintaining spherical particle separation effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A bypass passage acts as an intermediary path between the inlet and collection chamber. Filament-like particles that would otherwise clog the main separation path are diverted through this intermediate bypass, allowing them to be transported without obstructing the primary cyclone separation function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If cyclone openings are used for particle separation, then spherical particles are filtered effectively, but filament particles obstruct the openings

Engineering Contradiction:

Improveparticle filtrationVSAvoidobstruction

Core Design Contradiction:

Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The filtration system is segmented into a main cyclone path with precision openings for spherical particles and a separate bypass passage for filaments. This segmentation ensures that the precision openings maintain their filtration capability while filaments are routed through the bypass, eliminating obstruction.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The harmful effect of filament obstruction is extracted from the main cyclone separation path by providing a dedicated bypass passage. Filaments are removed from the critical separation zone and transported through the bypass, allowing the precision cyclone openings to function without obstruction.

Inventive Principle:

Principle #2Taking out (Extraction)

3Productivity

If the cyclone chamber handles large quantities of filament bodies, then aspiration capacity is maintained, but clogging degrades flow field and reduces performance

Engineering Contradiction:

Improveaspiration capacityVSAvoidflow field stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The flow path is segmented into a bypass channel for filaments and a separation chamber for spherical particles. This allows the system to maintain high aspiration capacity by routing filaments through the bypass while preserving flow field stability in the separation chamber, preventing clogging-related performance degradation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bypass passage ensures continuous transport of filament particles without interruption or clogging. By providing an uninterrupted flow path for filaments, the system maintains continuous aspiration capacity while the separation chamber maintains stable flow field conditions for spherical particle separation.

Inventive Principle:

Principle #20Continuity of useful action
