Diamond Wire Saw Dust Cover With Compressed-Air Wire Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collection systems for diamond wire saws are inefficient in removing foreign matter from the cutting wire, leading to environmental pollution and high manufacturing costs due to the need for large, expensive facilities that only collect dust from the cutting plane and not the wire itself.
Innovation Solution
A dust collection system using a transparent cover with adjustable cut recess members and compressed air to spray and remove foreign matter from the cutting wire, combined with a wire saw apparatus featuring auxiliary rollers to prevent wire separation and enhance cutting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a large-sized dust collection facility is customized for nuclear power plant structures, then foreign matter collection capability is improved, but manufacturing cost and manufacturing time increase
Solution Approach 1:
The system segments the dust collection function into a compact, modular design with the collection container positioned only where needed under the cutting plane, rather than requiring a large facility encompassing the entire cutting area. This reduces manufacturing cost and time while maintaining effective foreign matter collection capability.
Solution Approach 2:
The wire cleaning device uses compressed air from the air compressor to automatically clean the cutting wire through the transparent cover, eliminating the need for manual wire cleaning operations. This self-service cleaning function reduces operational complexity and costs while maintaining cutting efficiency.
2Object-generated harmful factors
If a transparent cover is used to hermetically seal the structure, then dust collection effectiveness is improved, but visibility for monitoring the cutting process is reduced
Solution Approach 1:
The cover is made of transparent material that allows light to pass through, maintaining visibility for monitoring the cutting process while still providing hermetic sealing for effective dust collection. The transparency property resolves the contradiction between sealing effectiveness and visual accessibility.
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 system effectively removes foreign matter from both the cutting wire and plane using compressed air, reduces the need for large facilities, and extends the lifespan of the cutting wire, thereby improving cutting efficiency and reducing costs.
Implementation Method 1
an air compressor (140) configured to supply compressed air
Implementation Method 2
a packing member configured to wrap at least a part of an inner circumferential surface of each of the plurality of cut recess members while wrapping at least a part of an outer circumferential surface of the passage member such that frictional force is formed between the passage member and the packing member
