Filter Insert Flange Guide Structure for Liquid Separator Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter inserts for liquid separators, such as air/oil separators, are difficult to install correctly and risk being used in incompatible systems, leading to potential errors and inefficiencies in oil separation from compressed air.
Innovation Solution
The filter insert features a guide structure, such as a groove-like axial elevation on the flange, which engages a complementary counter structure on the liquid separator, ensuring precise alignment and preventing incorrect installation, thereby ensuring the filter insert is used only in compatible systems and maintaining operational safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flange is used to mount the separation element in the housing, then the separation element can be securely fixed, but the filter insert can be installed in incorrect positions or in incompatible systems
Solution Approach 1:
The guide structure on the flange is designed with an asymmetric geometry that corresponds to a specific counter structure on the housing. This asymmetric design ensures that the flange can only be mounted in the correct orientation and on the compatible housing type, preventing incorrect installation while maintaining secure fixing.
2Manufacturing precision
If the flange is designed with a simple support surface, then the structure is simple, but the filter insert cannot be precisely positioned or centered
Solution Approach 1:
The flange is segmented into functional zones: a support surface for mounting and a guide structure for positioning. The guide structure includes groove-like axial elevations that engage with corresponding counter structures on the housing, providing precise positioning without requiring a completely complex flange design.
3Manufacturing precision
If guide structures are added to the flange for precise positioning, then installation accuracy is improved, but the flange structure becomes more complex
Solution Approach 1:
The guide structure is implemented as localized groove-like axial elevations on the flange rather than a completely complex design. These localized features engage with corresponding counter structures on the housing to provide precise positioning, achieving high installation accuracy with minimal additional structural complexity.
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
This solution simplifies and ensures error-free installation of the filter insert, ensuring it is used in matching liquid separators, enhancing operational safety and efficiency by preventing incorrect positioning and ensuring proper sealing and centering of the separation element.
Implementation Method 1
the guide structure is at least one groove-like axial elevation of the flange projecting away from the end face of the separation element that is configured to receive substantially with precise fit at least one counter structure correlated with the liquid separator
Implementation Method 2
The at least one hollow cylindrically configured filter element is configured as a hollow cylindrical coalescer that combines the fine oil droplets to larger oil drops that, due to gravity, precipitate downwardly in the air/oil separation element
Implementation Method 3
combines the fine oil droplets to larger oil drops that, due to gravity, precipitate downwardly

AI summary
A filter insert to be installed in a housing of a liquid separator has a hollow cylindrical separation element in the form of a coalescer for separating a liquid from a gas flow. A flange at an end face of the hollow cylindrical separation element can be arranged exchangeably between a cover and a cylindrical body of the housing. The flange has a support surface at a radially outer rim of the flange to be supported on an upper support region of the housing facing the cover of the housing. The flange has a guide structure determining a position of the flange on the upper support region of the housing. The guide structure is to receive a counter structure of the liquid separator. The guide structure has an axial elevation projecting away from the end face of the separation element. A liquid separator is provided with such a filter insert.
