Cyclone Dust Collector Sealing Structure for Low Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclone dust collectors experience air leaks and pressure loss due to poorly sealed connecting portions, leading to weakened suction force and complex configurations requiring separate sealing devices.
Innovation Solution
A cyclone dust collector design that integrates a blocking plate with protrusion pipes and cones for internal sealing, combined with an elastic cover unit and gasket for airtight connections, minimizing pressure loss and simplifying the configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate sealing devices or sealing members are added to seal between components, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The sealing function is merged with the connecting structure itself. The blocking plate integrates both the connection function (connecting the second cyclone unit to the first cyclone unit) and the sealing function (providing sealing surfaces through protrusion pipes and holes). This eliminates the need for separate sealing devices while maintaining sealing reliability.
Solution Approach 2:
The connecting structure performs self-sealing through its own geometric features. The protrusion pipes and holes on the blocking plate create inherent sealing surfaces that seal automatically when components are assembled, without requiring external sealing members or additional sealing actions.
2Device complexity
If conventional connecting portions are used without integrated sealing, then device complexity is reduced, but air leaks and pressure loss occur
Solution Approach 1:
The sealing function is merged with the connecting structure itself. The blocking plate integrates both the connection function (connecting the second cyclone unit to the first cyclone unit) and the sealing function (providing sealing surfaces through protrusion pipes and holes). This eliminates the need for separate sealing devices while maintaining sealing reliability.
