Movable Surface Belt for Dry Paint Mist Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing paint mist from paint booths are either expensive or environmentally questionable, particularly when using wet separation or dry cleaning methods that require frequent component replacement.
Innovation Solution
A device featuring a movable surface belt with interconnected U-shaped links in two layers, allowing paint mist to settle and be removed dryly, with automated sections for continuous operation and a paint cleaning device using laser heads for thorough cleaning outside the booth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wet separation methods or wet washing methods are used to remove paint mist, then paint mist removal effectiveness is improved, but operational cost increases and environmental compliance becomes questionable
Solution Approach 1:
The invention extracts the paint mist removal function from complex wet separation systems and implements it through a simple dry filtration mechanism using a filter element positioned in the exhaust air flow path, eliminating the need for water-based separation systems
Solution Approach 2:
The filter element is designed as a replaceable, cost-effective component that can be easily exchanged when saturated with paint mist, replacing expensive and complex wet separation systems while maintaining effective paint mist removal
2Device complexity
If dry cleaning methods with frequent component replacement are used, then operational cost is reduced, but productivity decreases due to frequent maintenance interruptions
Solution Approach 1:
The filter element is pre-designed with high capacity and optimized geometry to maximize service life before replacement is needed, allowing extended continuous operation without maintenance interruptions
Solution Approach 2:
The movable surface belt continuously transports the filter element through the paint booth environment, allowing dynamic operation where the filter element is exposed to paint mist during operation and automatically removed for cleaning or replacement without shutting down the system
3Productivity
If a movable surface belt with interconnected links is used, then continuous dry cleaning is enabled, but device complexity increases compared to simple filtration
Solution Approach 1:
The movable surface belt with interconnected links serves multiple functions simultaneously: it supports the filter element, transports it through the paint booth, enables continuous exposure to paint mist, and facilitates automatic removal for cleaning, replacing multiple separate systems with a single integrated mechanism
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
Enables efficient, cost-effective, and environmentally friendly dry cleaning of paint mist without the need for frequent component replacement, allowing continuous operation and thorough cleaning of the belt sections for re-use within the booth.
Implementation Method 1
The air transporting the paint mist passes through these members and is deflected at the edges of the individual U-profiles. As a result, centrifugal forces act on the paint mist particles, which promote their contact with the members of both layers.
Implementation Method 2
Paint mist can be deposited on the strand, and the deposited paint mist is then moved out of the paint booth with the movable surface belt.

AI summary
In a device for removing paint mist from an exhaust air stream, in particular paint overspray mist in a paint booth, it is provided that at least one wall of the room is assigned at least sectionally to a section of at least one surface band and that at least one paint cleaning device is assigned to the section.
