V-Shaped Cartridge Filter With Integrated Grids for Low-Leakage Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cartridge filters for gas turbines and air-conditioning systems face challenges in assembly complexity, instability due to numerous components, and structural weaknesses leading to potential leaks and damage during operation.
Innovation Solution
A cartridge filter design featuring a frame with a simple, stable structure composed of a pair of filter media sets arranged in a V-shape, integrated protective grids, and base plate cross-members, forming a structural unit with positive-locking components to enhance stability and reduce the need for adhesive bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual components (protective grids, frame elements) are used in the filter assembly, then the filter medium can be securely fixed and protected, but the assembly becomes complex and the force path configuration becomes difficult to manage
Solution Approach 1:
The protective grid is integrated directly into the base plate cross-member as a single structural unit. The protective grid forms part of the base plate cross-member structure, eliminating the need for separate protective grid components and their associated mounting mechanisms. This merging reduces assembly complexity while maintaining the protective function.
2Strength
If a large quantity of casting compound is used to secure protective grids and frame elements, then the connection strength is improved, but the structural stability decreases and leakage may occur
Solution Approach 1:
The protective grid is extracted from the casting compound bonding process and integrated as a structural component of the base plate cross-member. This eliminates the need for extensive casting compound usage to secure separate protective grid components, thereby reducing the risk of leakage while maintaining connection strength through the integrated structure.
3Adaptability or versatility
If multiple separate components are assembled together, then the filter can be constructed with functional protection, but the structural space required for connections and assembly increases
Solution Approach 1:
The protective grid and base plate cross-member are merged into a single integrated structural unit. This eliminates the structural space that would otherwise be required for separate mounting features, connection seams, and assembly clearances, thereby reducing the overall structural volume while maintaining the protective function.

AI summary
A cartridge filter for filtering an air flow, including a plurality of filter media sets including a pair of filter media sets arranged in a V-shape and a frame for receiving the filter media sets. The frame has an inflow-side upper frame, two side plates, and a plurality of outflow-side base plate cross-members. A base plate cross-member is associated with the pair of filter media sets arranged in the V-shape. The cartridge filter further includes protective grids. Each protective grid is associated with a respective filter media set of the plurality of filter media sets at a clean gas side. The protective grids associated with the pair of filter media sets and the base plate cross-member form a structural unit.
