Stone Saw Axial Flushing and Blade Flange Spray Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stone saws lack efficient flushing mechanisms, leading to suboptimal sawing speed and sludge removal during the process of cutting drill cores, which hampers the examination of mineral resources in the mining industry.
Innovation Solution
The stone saw incorporates a rotation axle with axial flushing channels and blade flanges featuring crosswise spray openings connected to the flushing system, allowing for efficient directional feeding of flushing fluid between the blade and sample, enhancing sludge removal and cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional stone saw configuration is used without axial flushing channels, then device complexity is reduced, but flushing efficiency and sludge removal capability deteriorate
Solution Approach 1:
The flushing channels are nested within the rotation axle structure itself, utilizing the hollow interior of the axle to convey flushing fluid directly to the blade. This integration eliminates the need for separate external flushing conduits while maintaining effective sludge removal capability.
Solution Approach 2:
The rotation axle serves as an intermediary component that transports flushing fluid from the external flushing system to the sawing site at the blade. By incorporating axial flushing channels in the axle, the system efficiently delivers cooling and flushing fluid directly where needed without complex external piping.
2Productivity
If crosswise spray openings are added to blade flanges, then flushing fluid delivery to sawing site is improved, but manufacturing complexity increases
Solution Approach 1:
The blade flange is segmented with multiple crosswise spray openings distributed across its surface, allowing flushing fluid to be delivered from multiple angles and positions. This segmentation enhances flushing effectiveness and cooling efficiency while the openings can be manufactured using standard drilling or machining operations.
Solution Approach 2:
The blade flange is designed with localized spray openings at specific positions to optimize flushing fluid delivery to the sawing site. The crosswise orientation of openings provides targeted cooling and sludge removal at critical areas of the blade-contact zone without requiring complex overall structural changes.
3Productivity
If flushing fluid is fed crosswise to sawing site, then sludge removal efficiency is improved, but device complexity increases
Solution Approach 1:
The flushing fluid delivery is extended into the crosswise dimension by incorporating spray openings in the blade flange that orient flushing fluid perpendicular to the rotation axle axis. This dimensional addition enables effective sludge removal from the sawing site without requiring complex mechanical moving parts or additional actuation mechanisms.

This configuration improves sawing speed and efficiency by effectively controlling and directing flushing fluid, leading to improved removal of sawing sludge and cooling of the circular blade, thereby optimizing the stone sawing process.
Implementation Method 1
a rotation axle (5) comprises at least one axial-direction flushing channel (16)
Implementation Method 2
at least one blade flange (8) comprises several crosswise spray openings (18) that are connected to the flushing channel (16) of the rotation axle (5)
Implementation Method 3
the flushing fluid is fed from said spray openings (18) to the sawing site (13) in the crosswise direction of the rotation axle (5)
Implementation Method 4
During sawing, flushing fluid is fed to flush away the sawing sludge formed during sawing in the sawing site

AI summary
A stone saw for sawing drilling samples. The stone saw includes a rotation axle provided with an axial flushing channel. On the rotation axle a circular blade is arranged. On at least one side of the circular blade is a blade flange, which includes several spray openings that are connected to the flushing channel of the rotation axle. Flushing fluid may then be sprayed on a sawing site.
