Adjustable Slurry Sprayer for Clean Silicon Ingot Wafering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slurry sprayers are difficult to clean thoroughly and their position cannot be adjusted to maintain effective cooling efficiency during silicon ingot slicing due to wear of the main roller, leading to poor cooling performance.
Innovation Solution
A slurry sprayer with detachable components for easy cleaning and an adjustable support system that allows for horizontal, vertical, and angular adjustments to maintain optimal cooling performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional slurry sprayers are made by integrated molding, then manufacturing is simplified, but cleaning becomes difficult and impurities cannot be thoroughly removed
Solution Approach 1:
The slurry sprayer is divided into multiple detachable components including a body, cover, and nozzle assembly that can be separated for thorough cleaning. This segmentation allows each component to be cleaned independently, removing the cleaning difficulties associated with integrated molding while maintaining manufacturing efficiency through modular assembly.
Solution Approach 2:
The slurry sprayer design incorporates adjustable components that can be repositioned and reconfigured. The adjustable support system allows the sprayer to adapt to changing main roller profiles, maintaining optimal cooling efficiency throughout the slicing process despite wear-induced dimensional changes.
2Duration of action of stationary object
If the main roller surface is flattened and smoothed to extend its service life, then the roller can be used for longer periods, but the diameter decreases and contact position with the wire lowers
Solution Approach 1:
The slurry sprayer is mounted on an adjustable support system that enables continuous repositioning to compensate for main roller wear. As the roller diameter decreases over time, the sprayer can be adjusted vertically and angularly to maintain optimal contact position and cooling efficiency, resolving the contradiction between extended roller life and maintained precision.
Solution Approach 2:
The adjustable support system allows modification of the sprayer's position parameters (vertical height, horizontal position, and angle) to adapt to changing roller dimensions. This parameter adjustment capability ensures that cooling performance remains optimal despite the roller's dimensional changes during extended use.
3Stability of the object's composition
If conventional slurry sprayers are soldered in the wire saw, then the structure is fixed and stable, but adjustment of the sprayer position is prevented
Solution Approach 1:
The slurry sprayer is mounted on an adjustable support structure that replaces permanent soldering with mechanical fastening systems. This allows the sprayer to be securely attached while enabling position adjustments in multiple directions, achieving both structural stability and adaptability to changing operational conditions.

AI summary
A slurry sprayer for supplying a slurry to a wire saw during ingot slicing is disclosed. The slurry sprayer includes a main body and a cover plate that is detachable from the main body for cleaning the slurry sprayer. In some embodiments, the slurry sprayer includes an adjustable support that allows the incline angle of the sprayer to be adjusted and allows the vertical and horizontal position of the slurry sprayer to be adjusted. In some embodiments, the slurry sprayer includes two feed openings to allow the slurry pressure to be more equalized across the slurry sprayer.
