Magnetic Wiping Means for Plating Pot Dross Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing top dross from a plating pot are inefficient, particularly at high speeds, as they require significant manual labor and cannot effectively reach all areas, leading to reduced workability and safety concerns due to the high-temperature environment.
Innovation Solution
An apparatus with a snout and air knives, featuring first, second, and third wiping means, including magnetic wheels, guide rails, and pivotable components, which move and transfer top dross from inaccessible areas to regions where a dross removing robot can reach, utilizing uplift and drag forces to push the dross and prevent zinc attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual removal of top dross is used, then dross can be removed from the plating pot, but workability is notably reduced and significant manual labor is required
Solution Approach 1:
The magnetic wiping means automatically removes top dross through self-propelled movement along the plating pot surface, eliminating the need for manual labor. The system serves itself by using magnetic attraction to both propel and power the dross removal operation.
Solution Approach 2:
Manual mechanical dross removal is replaced with an automated magnetic system. The magnetic wiping means uses magnetic field forces instead of human physical effort to achieve dross removal, substituting a mechanical-automated system for manual operation.
2Extent of automation
If a dross removing robot is used, then automation is improved, but the robot cannot reach all areas of the plating pot
Solution Approach 1:
The magnetic wiping means is designed to be movable along the plating pot surface rather than fixed in position. This dynamic capability allows the system to adapt to different locations and reach areas that stationary robots cannot access, combining automation with spatial flexibility.
Solution Approach 2:
The system changes its positional parameters by moving along the plating pot surface. This ability to vary position enables the magnetic wiping means to cover the entire plating pot area, overcoming the limited coverage of fixed-position robotic systems.
3Productivity
If high-speed operation at 160 mpm or more is implemented, then productivity increases, but the amount of generated top dross rapidly increases
Solution Approach 1:
The magnetic wiping means operates continuously alongside the high-speed plating process, providing continuous dross removal. This continuous action ensures that even though dross generation increases at high speeds, the removal process keeps pace, maintaining effective dross control throughout the operation.
