Cone-Integrated Canvas Cleaning Device for Stain Re-adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canvas cleaning devices for paper machines face challenges in preventing re-adhesion of stains and achieving efficient cleaning due to the separation of stain preventive agent and high-pressure water spraying means, and the difficulty in bringing these devices close to each other in the dryer part, leading to suboptimal cleaning efficiency.
Innovation Solution
A canvas cleaning device with a cone part and high-pressure water spraying device installed inside, combined with a nozzle device attached to an arm part, where the cone and nozzle are aligned along the transporting direction, allowing for efficient spraying and application of chemical solutions, and a negative pressure generating device to ensure thorough cleaning and prevent re-adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the supply means for stain preventive agent and the high pressure water spraying means are separated and located with a fixed distance spaced from each other, then the device structure is simple and easy to install, but stains re-adhere to the canvas during transportation between the two means
Solution Approach 1:
The patent combines the supply means for stain preventive agent and the high pressure water spraying means into an integrated cleaning unit. This merging allows both functions to operate in close proximity, preventing stain re-adhesion while maintaining structural simplicity and ease of installation.
2Reliability
If the supply means and the high pressure water spraying means are brought close to each other to prevent stain re-adhesion, then cleaning effectiveness improves, but it becomes difficult to bring the two means close due to their large size and design constraints of the dryer part
Solution Approach 1:
The patent employs a nested structure where the supply means and high pressure water spraying means are integrated into a compact unit. This nesting approach allows the two large devices to be positioned close together by placing one within or adjacent to the other, reducing spatial requirements while maintaining cleaning effectiveness.
3Ease of manufacture
If conventional cleaning devices are used with separated means, then the device structure is simple, but the cleaning efficiency is suboptimal due to inability to maintain close proximity
Solution Approach 1:
The patent merges the supply means and spraying means into a unified cleaning system that maintains close proximity between functional components. This combination improves cleaning efficiency by preventing stain re-adhesion while preserving structural simplicity through integrated design.
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
The device effectively removes stains and moisture from the canvas, prevents re-adhesion, and ensures efficient cleaning by aligning the cone and nozzle parts to maintain close proximity, allowing for uniform application of high-pressure water and chemical solutions, thereby enhancing cleaning efficiency and compactness.
Implementation Method 1
a high pressure water spraying device for spraying high pressure water onto the canvas formed inside the cone part
Implementation Method 2
a negative pressure generating device for setting the inside of the cone part to a negative pressure, and inside the cone part, high pressure water is sprayed from the high pressure water spraying device onto the canvas, with the high pressure water being sucked by the negative pressure generating device
