Aerosol Filter Clamping Layout Outside the Raw Gas Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices have clamping elements located in the raw gas space, leading to increased space requirements and contamination of aerosols, as well as complex and labor-intensive maintenance due to the placement of clamping systems within the gas flow path.
Innovation Solution
The clamping elements are rearranged to be located between the clamping frame and the filter housing support surface, outside the flow path, ensuring a compact and simpler design while preventing contamination by aerosols, using a combination of seals and a pneumatic relief device for easy filter element removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping elements are located in the raw gas space to press the filter element, then the filter element can be securely clamped, but the filter housing is lengthened requiring additional space and the clamping elements are contaminated by aerosols
Solution Approach 1:
The clamping elements are moved from the longitudinal direction (raw gas space) to the transverse direction (perpendicular to flow direction), allowing the clamping mechanism to be positioned in a different spatial dimension that does not increase the filter housing length while maintaining clamping effectiveness
2Reliability
If clamping elements are located in the raw gas space, then the filter element can be clamped, but the clamping elements are contaminated by aerosols requiring time-consuming cleaning
Solution Approach 1:
The clamping elements are extracted from the raw gas space and positioned in the transverse direction outside the aerosol flow path, eliminating their exposure to contaminated gas and removing the need for cleaning operations
Solution Approach 2:
A seal is introduced as an intermediary component between the clamping elements and the raw gas space, creating a barrier that prevents aerosol contact with the clamping elements while maintaining the clamping function
3Device complexity
If a single clamping device is used to press the filter element, then the structure is simpler, but the sealing reliability is insufficient compared to dual clamping systems
Solution Approach 1:
Multiple sealing functions are merged into a single integrated seal component that simultaneously provides sealing at both the first end face and second end face of the filter element, maintaining high sealing reliability while simplifying the overall clamping device structure
Solution Approach 2:
The seal is designed with multi-functionality, serving as both a sealing element and a structural component that connects the clamping elements to the filter housing, reducing the total number of parts required
Applied Scientific Principles

Function Achieved in This Case
This configuration results in a more compact and easier-to-maintain filter device with reduced contamination of clamping elements, eliminating the need for time-consuming cleaning and simplifying the replacement process.
Implementation Method 1
The clamping elements consist of a compression spring (29) which pulls the clamping frame (15) against the filter element (3)
Implementation Method 2
a pneumatic cylinder (31) whose piston (32) is firmly connected to the threaded transmission element (30)
Implementation Method 3
a first seal (19) which surrounds an outlet opening of the filter element (3) and which is pressed by the clamping frame (15) against a first sealing surface (17)

AI summary
The device (1) has a rotating seal (20) arranged between a rotating sealing surface (17) of a clamping frame (15) and a front surface (18) of an element framework (12). The frame is sealingly attached to a filter housing (8) by a circulating seal (21). A clamping device (10) has a clamping unit (16) for producing stress, where the frame is transferred from an operating position (2) into a changeover position. The seal (21) is varied in a direction of motion of the frame in length and/or is adjusted relative to the housing such that the seal (21) is effective in the positions.
