Modular Filter Device With Detachable Purging Gas Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices for gas filtration, such as those used in internal combustion engines, lack a simple and modular solution for incorporating a purging device to effectively clean deposits from the filter medium body.
Innovation Solution
A filter device with a fastening flange at the flow socket allows for the detachable attachment of a purging gas pipe, enabling the introduction of a purging medium to detach deposits, and can be optionally retrofitted with a purging device by replacing a closure lid, with the possibility of multiple openings and flanges for enhanced cleaning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a purging device is integrated into the filter device, then the filter medium body can be cleaned effectively, but the device complexity increases
Solution Approach 1:
The purging device is designed as a separate, modular component that can be attached to or removed from the filter device. The purging gas pipe is detachably connected to the flow socket, allowing the purging function to be segmented from the main filtration system. This reduces the complexity of the overall device while maintaining the cleaning effectiveness when needed.
Solution Approach 2:
The flow socket is designed with a universal function: it serves both as the discharge socket for purified medium during normal filtration operation and as the connection point for the purging gas pipe when cleaning is needed. The fastening flange enables the same structural feature to accommodate both the closure lid and the purging gas pipe, reducing the need for separate dedicated components.
2Device complexity
If the purging device is made detachable, then the device complexity is reduced, but the ease of operation for cleaning decreases
Solution Approach 1:
The fastening flange is pre-integrated into the flow socket during manufacturing, with threaded connections already prepared. This preliminary preparation of the connection interface eliminates the need for complex assembly steps when attaching the purging gas pipe. The closure lid is also pre-configured with a corresponding fastening structure, so that both the lid and purging pipe use the same pre-prepared interface, simplifying the attachment operation.
3Productivity
If multiple openings are provided in the flow socket, then the cleaning performance is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
Instead of integrating multiple complex features into a single monolithic flow socket, the design segments the connection points as separate openings that can be independently positioned. Each opening can be optimally located for its specific function (purging gas inlet, additional purging points) without compromising the precision requirements of other features. The modular nature of the openings allows for easier manufacturing and assembly.

Function Achieved in This Case
Enables efficient and modular cleaning of filter medium deposits, allowing for optional inclusion of a purging device to improve filtration performance and maintain filter efficiency over time.
Implementation Method 1
a purging medium is introduced under pressure into the inwardly positioned flow chamber, whereupon the deposits at the exterior side of the filter medium body become detached by the pressure pulse of the purging medium

AI summary
A filter device has a filter housing and a filter element arranged in the filter housing. The filter element at least partially encloses an inwardly positioned flow chamber. A purified medium can be discharged from the filter device through a flow socket provided with a wall that has an opening. A fastening flange is arranged at the wall of the flow socket adjacent to the opening, wherein a purging gas pipe of a purging device can be detachably fastened by the fastening flange to the flow socket. The opening in the wall of the flow socket receives the purging gas pipe.
