Integrated Filter Seal Carrier for Reliable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices require frequent and complex filter element changes, especially under high pressure and large volumetric flows, with a risk of incorrect or forgotten sealing elements leading to environmental pollution.
Innovation Solution
The sealing arrangement is integrated as a component of the filter element, securely fixed on a seal carrier, ensuring automatic replacement during filter element changes, eliminating the risk of incorrect installation and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing element is provided as an additional part for replacement filter elements, then the sealing function can be ensured, but the logistics are complicated and the risk of incorrect or forgotten installation increases
Solution Approach 1:
The sealing arrangement is merged with the filter element to form an integrated assembly. The sealing arrangement is fixed on a seal carrier that is securely connected to the filter element, ensuring that when the filter element is replaced, the sealing arrangement is automatically replaced as well. This eliminates the need for separate logistics management of sealing elements and filter elements.
Solution Approach 2:
The sealing arrangement is pre-installed on the seal carrier during manufacturing, before the filter element needs to be replaced in operation. This preliminary action ensures that the sealing element is already in the correct position and orientation, eliminating the risk of forgotten or incorrect installation during maintenance operations.
2Reliability
If the sealing element is provided as an additional part, then sealing can be achieved, but the risk of incorrect installation increases leading to environmental pollution
Solution Approach 1:
By combining the sealing arrangement with the filter element into a single integrated unit, the patent eliminates the human error risks associated with separate component installation. The integrated design ensures that the sealing function is always present when the filter element is installed, preventing environmental pollution from incorrect or forgotten sealing element installation.
3Device complexity
If the seal carrier is connected to the end cap by radial crosspieces, then the structure is simplified, but the fluid flow path must remain unobstructed
Solution Approach 1:
The seal carrier is segmented into a central part and a peripheral part connected by radial crosspieces. This segmentation allows the structure to be simple and manufacturable while the crosspieces are positioned to minimize interference with the fluid flow path, maintaining productivity.
