Cyclone Separator Bottom Inlet Design to Reduce Filter Dust Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclone separators in dust collectors face issues with dust adhering to central filters due to poor air intake direction and sealing between the air inlet pipe and cyclone, leading to reduced dust-collection efficiency and increased maintenance costs.
Innovation Solution
A cyclone separator design with a bottom wind intake and spiral airflow path, utilizing a wind guiding plate and shielding plate to direct dust away from the filter, preventing adherence and improving separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air with dust enters from the side wall of the cyclone, then the cyclone can be simple in structure, but dust adheres to the central filter blocking it
Solution Approach 1:
The patent inverts the conventional air inlet position from the side wall to the bottom wall of the cyclone. This inversion changes the airflow direction so that air enters upward through the wind guiding plate rather than inward from the side, preventing dust from directly contacting and adhering to the central filter.
Solution Approach 2:
The wind guiding plate serves as an intermediary component between the air inlet and the cyclone chamber. It guides the airflow in a spiral pattern upward, mediating the interaction between dusty air and the filter by controlling the flow path to avoid direct contact with the filter surface.
2Ease of manufacture
If the cyclone has a cylinder shape for simplicity, then manufacturing is easier, but sealing between air inlet pipe and cyclone is poor
Solution Approach 1:
The air inlet pipe is designed with a curved structure that tangentially connects to the cyclone chamber. This curved geometry provides both structural simplicity for manufacturing and effective sealing by creating a natural fit between components, eliminating the need for complex sealing mechanisms.
3Device complexity
If dust is thrown out at lower position, then the cyclone structure is simpler, but dust and hair are not separated completely
Solution Approach 1:
The wind guiding plate extends upward in a spiral shape, adding a vertical dimension to the dust separation process. This upward spiral extension increases the separation height and path length, allowing more complete separation of dust and hair before discharge, while maintaining structural simplicity through the spiral geometry.
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 enhances filter longevity, reduces cleaning frequency, and maintains high dust collection efficiency by preventing dust from adhering to the filter and ensuring effective separation of dust and hair, thus prolonging the operational life of the filter and reducing maintenance costs.
Implementation Method 1
air with dust entering the cyclone turns into a spiral airflow quickly, and the dust is thrown away from the filter under a centrifugal force
Implementation Method 2
the airflow with dust rises and speeds up on the wind guiding plate and then is thrown out of the cyclone, so that the dust is separated from the air quickly and completely

AI summary
A cyclone separator is provided. The cyclone separator includes: a cyclone, an end cover of the cyclone separator, a filter and a wind guiding cylinder. The cyclone has an open end and a bottom wall defining an inlet of the cyclone separator therein. The end cover of the cyclone separator is disposed over the cyclone and defines an outlet of the cyclone separator therein. The filter has an upper end communicating with the outlet of the cyclone separator and a lower end extended into the cyclone. The wind guiding cylinder has a lower end communicating with the inlet of the cyclone separator, a closed upper end and a side wall defining a vent communicating with the cyclone.
