Cyclone Dust Collector Gap Structure to Prevent Filter Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collectors for cleaners face issues with blocking due to large, lightweight inclusions like facial tissue, which hinder the separation performance of cyclone barrels.
Innovation Solution
A dust collector design featuring a cyclone barrel with an open upper end spaced apart from a flange, creating a gap that allows large inclusions to be collected in the dust-collection container, preventing blockages and enhancing separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dust discharging port is formed in the cyclone barrel for centrifugal filtration, then dust particles can be discharged into the dust-collection container, but large lightweight inclusions (e.g., facial tissue) cannot pass through and block the filter
Solution Approach 1:
The dust collection system is segmented into two distinct discharge paths: a dust discharging port in the cyclone barrel for fine dust particles, and a separate inclusion collection chamber accessible through an open upper end for large lightweight inclusions. This segmentation allows each component to handle specific types of debris, preventing blockages in the filter while maintaining reliable dust collection.
Solution Approach 2:
The open upper end of the cyclone barrel acts as an intermediary structure between the dust-laden air inlet and the dust-collection container. It provides a intermediate collection zone where large inclusions can be captured and removed separately, preventing them from reaching and blocking the filter while allowing fine dust to continue through the normal centrifugal filtration process.
2Reliability
If the cyclone barrel structure is sealed to maintain centrifugal force, then separation performance is improved, but the structure becomes more complex and harder to maintain
Solution Approach 1:
The cyclone barrel is segmented into a sealed lower portion for maintaining centrifugal force and separation performance, and an open upper end for simplified access and maintenance. The sealed portion contains the dust discharging port and filter interface, while the open upper end provides access to the inclusion collection chamber, reducing overall structural complexity.
Solution Approach 2:
The design adds a vertical dimension to the cyclone barrel structure by opening the upper end, transforming it from a completely enclosed cylindrical chamber to a partially open structure. This dimensional change allows large inclusions to be collected and removed from the top, simplifying maintenance without compromising the sealed centrifugal separation environment in the lower portion.
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
The design improves dust collection reliability, simplifies structure, reduces maintenance costs, and enhances dust collection capacity by facilitating the passage of large inclusions and improving air circulation.
Implementation Method 1
When dust-laden air is sucked into the cyclone barrel along a tangent direction of the cyclone barrel through a dust-laden air inlet of the dust-collection container, the dust particles with a high density are thrown onto an inner wall of the cyclone barrel under a centrifugal force
Implementation Method 2
a filter disposed in the dust-collection container and having a filtering cup and a flange disposed on an upper end of the filtering cup
