Flake Cleaning Media Airflow Impact for Deposit Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning methods for removing flux and photosensitive layers from pallets and drums are inefficient, environmentally harmful, and costly, particularly due to the use of solvents and abrasive blasting, which require high energy consumption and lead to material deformation and recycling challenges.
Innovation Solution
A cleaning device utilizing flake-shaped cleaning media that are accelerated by a circulating air flow to collide with and remove film-like deposits from objects, with a recycling system to collect and reuse the media, ensuring the pencil hardness of the media is greater than the deposit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solvent-based removers are used to remove flux or photosensitive layers, then the deposit is effectively dissolved and removed, but the remover cannot be reused, disposal causes environmental problems, and safety issues arise from highly-flammable solvents
Solution Approach 1:
The patent replaces chemical dissolution methods with mechanical impact methods. Flake-shaped cleaning media are accelerated by air flow to collide with and mechanically remove deposits through impact force, eliminating the need for chemical solvents and their associated environmental and safety problems
Solution Approach 2:
The invention uses pneumatic air flow to accelerate flake-shaped cleaning media to high speeds. The compressed air system propels the cleaning media through a nozzle onto the deposit, providing the mechanical force needed for effective removal without chemical substances
2Reliability
If abrasive blasting or grinding methods are used to remove deposits, then the deposit is effectively removed, but the objects may be deformed during the cleaning process
Solution Approach 1:
The patent changes the physical parameters of the cleaning media by using flake-shaped particles with specific size ranges (0.1-5mm) and controlling their acceleration speed through air flow pressure. These parameter optimizations allow effective deposit removal while reducing the risk of object deformation compared to traditional abrasive blasting
3Reliability
If traditional cleaning methods are used, then deposits are removed, but high energy consumption is required for drying processes and waste liquid disposal
Solution Approach 1:
The patent replaces wet chemical cleaning methods with dry mechanical impact cleaning. Since no liquid solvents are used, there is no waste liquid requiring energy-intensive drying processes, significantly reducing overall energy consumption while maintaining effective deposit removal
Solution Approach 2:
The cleaning media are designed to be reusable and are continuously circulated through the system. After impacting the deposit, the flake-shaped media are collected and reused multiple times, reducing the need for continuous material input and associated processing energy
