Vacuum Water Collection Trough for Wet Saw Slurry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water cooled saws cutting through ground surfaces, such as concrete or asphalt, generate significant waste water that can pollute groundwater and create a slurry, which discolors the cut surface, and existing solutions fail to effectively collect and manage this waste efficiently.
Innovation Solution
A water collection device comprising a trough with an elongated opening to accommodate the saw blade, connected to a vacuum system via a flexible hose, allowing for the collection of waste water and slurry from the trench, with a self-leveling mechanism to maintain contact with the ground and a seal to prevent water escape, utilizing a vacuum source to suction the waste into the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water is used to cool the saw blade during cutting, then the saw blade is protected from overheating and maintains cutting efficiency, but waste water is generated that pollutes groundwater and creates slurry that discolors the cut surface
Solution Approach 1:
The invention extracts the harmful waste water and slurry from the cutting area using a vacuum system. A vacuum hose is positioned to suction waste water from the trench area, separating it from the cutting environment and preventing pollution of groundwater and cut surface.
Solution Approach 2:
The invention introduces a vacuum system as an intermediary mechanism between the waste water generation point and the discharge point. The vacuum system acts as a mediator to actively remove and transport waste water away from the cutting area, preventing direct contact with groundwater and the cut surface.
2Object-generated harmful factors
If a waste water collection system is implemented, then groundwater pollution is prevented, but the device complexity increases
Solution Approach 1:
The invention makes the vacuum system multi-functional by using it for both waste water collection and slurry removal. The same vacuum hose and vacuum source handle multiple functions (collecting waste water from the trench and removing slurry from the cut surface), thereby reducing overall system complexity despite the added collection capabilities.
3Adaptability or versatility
If the trough is designed to accommodate various saw blade sizes, then the device becomes more versatile, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The invention employs a self-leveling mechanism with adjustable brackets that allow the trough to dynamically adapt to different blade sizes and cutting depths. The brackets can be adjusted to position the trough correctly for various blade diameters, providing versatility without requiring complex custom manufacturing for each blade size.

AI summary
Provided is a waste water collection device for collecting waste water dispelled from a water cooled saw. The device has a trough defining an elongated opening through the top, center and bottom of the trough to allow a water cooled saw blade to pass through the opening and contact a ground surface to be cut. The trough is constructed to retain waste water leaving the water cooled saw during use. A saw connection is constructed for connecting the trough to a water cooled saw so that the saw is within the opening of the trough. A waste water outlet is constructed to remove waste water retained within the trough. A flexible hose is constructed to remove a slurry from a trench cut by the saw during use. A vacuum connector is constructed for connecting a vacuum source to the waste water outlet and flexible hose. Also provided is a method of collecting waste water dispelled from the water cooled saw cutting the ground using the device.
