Elastomeric Gasket with Segmented Flat and Bulb Profiles for Vibrating Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibrating screen machines face challenges in achieving both an adequate seal and efficient transmission of vibrational energy due to difficulties in designing gaskets that can effectively seal without dampening the vibrational energy, leading to hampered performance.
Innovation Solution
A screen assembly with an elastomeric gasket having a flat profile section for rigid mounting and a compressible bulb profile section for a fluid-tight seal, allowing for the transmission of vibrational energy while minimizing dampening, where the compressible section is more compressible than the flat profile section and can be made of materials like foam rubber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compressible gasket is used to provide a fluid-tight seal, then sealing performance is improved, but vibrational energy transmission is dampened
Solution Approach 1:
The gasket is segmented into two distinct sections: a flat profile section for rigid mounting that transmits vibrational energy, and a compressible bulb profile section for sealing that prevents fluid leakage. This segmentation allows each section to perform its specific function without compromising the other.
Solution Approach 2:
Different sections of the gasket have different physical properties tailored to their specific functions. The flat profile section has rigid properties for energy transmission, while the bulb profile section has compressible properties for sealing. This local differentiation of material properties resolves the contradiction between sealing and energy transmission.
2Loss of energy
If a rigid gasket is used for rigid mounting, then vibrational energy transmission is improved, but sealing performance deteriorates
Solution Approach 1:
The gasket is divided into functional segments where the flat profile section provides rigid mounting for energy transmission, while the bulb profile section provides compressible sealing. This segmentation eliminates the need to choose between rigid and compressible properties.
Solution Approach 2:
The gasket exhibits different mechanical properties at different locations: rigid properties where energy transmission is needed and compressible properties where sealing is needed. This spatial variation in material properties simultaneously satisfies both requirements.
3Reliability
If gaskets are adhered to the deck, then sealing is achieved, but gasket replacement becomes time-consuming and difficult
Solution Approach 1:
The gasket is designed as a removable component that can be detached from the screen assembly without damaging the deck. This segmentation allows the gasket to be easily replaced when worn, while still providing sealing functionality during operation.
Solution Approach 2:
Instead of adhering the gasket to the fixed deck, the invention inverts the attachment approach by making the gasket a removable part of the screen assembly that can be easily detached and replaced, while still achieving the sealing function through its compressible bulb profile section.
