Paint Booth Filter Module With Replaceable Porous Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter modules in paint booths have a smooth surface that limits the separation of paint and varnish residues, leading to inefficient filtration and increased waste due to non-reusable components.
Innovation Solution
A filter module with column-shaped or trough-shaped support bodies and a separation medium fixed in a force-fitting and/or form-fitting manner, allowing for high-density cell arrangements and easy replacement or recycling of the separation medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smooth surface filter is used, then the filter structure is simple and easy to manufacture, but the separation capacity for paint and varnish residues is limited
Solution Approach 1:
The invention applies porous separation media with high hole density (at least 20, preferably more than 40 cells) to the filter surface. These porous structures dramatically increase the separation capacity for paint and varnish residues while maintaining a relatively simple overall filter structure, resolving the contradiction between manufacturing simplicity and separation productivity.
2Stability of the object's composition
If the separation medium is permanently attached to the support body, then the filter structure is stable, but the separation medium cannot be replaced or recycled
Solution Approach 1:
The invention segments the filter into two distinct parts: a reusable support body and a replaceable separation medium. The separation medium can be attached or detached from the support body, allowing it to be replaced when saturated or damaged while the support body remains for continued use. This segmentation resolves the contradiction between structural stability and component replaceability.
Solution Approach 2:
The invention enables the separation medium to be discarded after use (when saturated with paint residues) and recovered/recycled through proper disposal methods. The support body is retained and reused, reducing waste and costs. This approach resolves the contradiction by allowing the separation medium to be temporary while the support structure remains permanent.
3Productivity
If high hole density is implemented, then the separation efficiency increases, but the cell wall thickness decreases making the structure more fragile
Solution Approach 1:
The invention employs specially designed porous separation media with high hole density (at least 20, preferably more than 40 cells) that maintain adequate structural strength. The porous structure is engineered to provide sufficient separation efficiency while preserving the mechanical integrity needed for practical filter operation, resolving the contradiction between separation productivity and structural strength.
