Cyclonic dust filter device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclonic dust filter equipment is inadequate for industrial applications as it can only perform single-stage dust filtering and fails to provide cleaner air when the cyclonic centrifugal force is insufficient or when dealing with smaller dust particles, which is not sufficient for industrial requirements.
Innovation Solution
The cyclonic dust filter device incorporates a trunk with a hollow flow channel, a dust filter hole, a first retaining wall, and a second retaining wall, which deflects airflow to create multiple impact zones, enhancing dust separation by changing airflow direction and reducing particle velocity, allowing for secondary dust filtering and improved air cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cyclonic dust filter structures are used, then the device structure is simple, but the dust filter effect does not meet industrial requirements
Solution Approach 1:
The cyclone separator is divided into multiple independent cyclone chambers (first cyclone chamber and second cyclone chamber) arranged in parallel within the same housing. Each chamber performs dust separation independently, allowing the system to achieve higher dust removal efficiency through multi-stage filtering while maintaining a compact integrated structure that doesn't excessively increase device complexity
Solution Approach 2:
Multiple cyclone chambers are nested within a single housing structure, with each cyclone chamber containing its own separator body, inlet, and outlet components. This nested arrangement allows the system to provide industrial-grade dust filtering capability while containing all components within a space-efficient configuration
2Manufacturing precision
If single ascending airflow filtering is used, then the device structure is simple, but cleaner air cannot be provided when cyclonic centrifugal force is insufficient or dust particles are small
Solution Approach 1:
The dust filtering process is segmented into multiple stages by dividing the cyclone separator into distinct chambers. The first cyclone chamber handles initial dust separation, while the second cyclone chamber provides secondary filtering for finer particles. This segmentation enables the system to address different particle size ranges effectively, achieving superior air cleanliness without requiring overly complex filtering mechanisms
Solution Approach 2:
The system employs multiple cyclone chambers in sequence, providing more dust separation action than a single chamber would deliver. This excessive action ensures that even small dust particles that might escape one cyclone are captured by subsequent chambers, guaranteeing cleaner air output while maintaining practical device complexity through efficient spatial arrangement

Function Achieved in This Case
This design enables the cyclonic dust filter device to provide cleaner air by effectively filtering dust through multiple cyclonic stages, ensuring cleaner air output and meeting industrial dust filter requirements.
Implementation Method 1
the airflow to-be-filtered forms a centrifugal airflow that contains a dust at a position of the dust filter hole and is discharged outside of the trunk
Implementation Method 2
a first impact zone is defined by the at least one first retaining wall for the centrifugal airflow striking to the first retaining wall and changing a direction of the centrifugal airflow

AI summary
A cyclonic dust filter device comprises a trunk, at least one first retaining wall, and at least one second retaining wall. The trunk comprises a channel, an air inlet end and an air outlet end disposed at two ends of the channel, and a dust filter hole communicating with the channel. The first and second retaining walls are respectively disposed correspondingly to the dust filter hole. When a dust-containing airflow to-be-filtered enters the channel from the air inlet end, the dust-containing airflow forms a centrifugal airflow that contains the dust and is thrown out of the channel at a position of the dust filter hole. The first and second retaining walls are respectively disposed on a traveling path of the centrifugal airflow, so that the centrifugal airflow sequentially strikes the first and second retaining walls to change the traveling direction and then discharges dust free clean air.
