Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of cooling liquids in machine tools leads to scattering and disruption, resulting in inefficiencies, health hazards, and increased costs due to loss and recirculation issues, as well as contamination of air intakes and respiratory problems from mist formation.
Innovation Solution
A system comprising a mist collector with a baffle filter, mesh filter, and air filters to remove cooling liquid droplets from the mist, allowing for recirculation and purification of the cooling liquid, and removal of pollutants from the air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling liquid is circulated to remove heat, then heat removal efficiency is improved, but cooling liquid is scattered and lost
Solution Approach 1:
The patent extracts the cooling liquid from the air mist through a series of filters. The baffle filter captures larger droplets, the mesh filter captures smaller droplets, and the carbon filter captures residual contaminants. This extraction process recovers the cooling liquid that would otherwise be lost to the environment, resolving the contradiction between effective heat removal and cooling liquid conservation.
Solution Approach 2:
The system recovers cooling liquid from the air mist and returns it to the cooling system. The collected cooling liquid is channeled back to the machine tool, allowing it to be reused for heat removal. This recovery process eliminates the need to continuously replace cooling liquid, addressing both the heat removal efficiency and cooling liquid loss contradictions.
2Productivity
If cooling liquid is scattered during operation, then cooling coverage is improved, but respiratory health hazards increase
Solution Approach 1:
The patent converts the harmful scattered cooling liquid mist into a beneficial recovered resource. By capturing the mist through filters and returning the cooling liquid to the system, the invention eliminates the health hazard while maintaining the cooling effectiveness. The previously harmful scattered droplets become a valuable recoverable resource.
3Productivity
If cooling liquid stream is disrupted into droplets, then cooling distribution is improved, but cooling liquid recovery becomes difficult
Solution Approach 1:
The patent uses segmented filtration stages to recover cooling liquid of different sizes. The baffle filter handles larger droplets, the mesh filter handles smaller droplets, and the carbon filter handles residual contaminants. This segmentation approach makes the recovery process effective for all droplet sizes, resolving the contradiction between improved cooling distribution and difficult recovery.
