Solution Overview
Problem
Existing coolant treatment apparatuses struggle with inappropriate discharge pressure control of cleaned coolant to machining points, leading to potential inefficiencies and risks of filter clogging.
Innovation Solution
A coolant treatment apparatus with multiple flow channels, filters, and pumps that allow for controlled discharge pressure management through selective supply of clean coolant to machining points and filters, utilizing pressure detection and control units to maintain optimal pressure levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaned coolant is supplied to both machining point and filter simultaneously, then coolant circulation is maintained, but discharge pressure control becomes difficult
Solution Approach 1:
The coolant supply system is divided into two separate flow channels: a first flow channel that supplies cleaned coolant to the machining point, and a second flow channel that supplies cleaned coolant to the filter. This segmentation allows independent pressure control for each destination, resolving the contradiction between maintaining circulation and controlling discharge pressure.
Solution Approach 2:
A pump is introduced as an intermediary device in the first flow channel to actively control and adjust the discharge pressure of coolant supplied to the machining point. This mediator enables precise pressure regulation independent of the filter supply, solving the pressure control difficulty.
2Reliability
If coolant is supplied preferentially to machining point, then discharge pressure is controlled, but filter cleaning may be insufficient
Solution Approach 1:
By separating the coolant supply into two independent flow channels with separate control mechanisms, the system can simultaneously ensure adequate pressure for machining point supply while maintaining sufficient flow rate for filter cleaning, eliminating the trade-off between these two functions.
Solution Approach 2:
The coolant treatment apparatus is designed to perform multiple functions simultaneously: it supplies cleaned coolant to the machining point with controlled pressure while also supplying coolant to the filter for continuous cleaning. The multi-functional design ensures both machining requirements and filter maintenance are met without compromise.
