Mist Collector Drain Layout for Machine Tool Coolant Carryover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools do not effectively discharge substances that pass through the filter of the mist collector, leading to accumulation of mist and minute chips within the machine tool.
Innovation Solution
Incorporating a drain mechanism that connects the mist collector to the machine tool's body, allowing substances that have passed through the first filter to be suctioned and discharged, along with a second filter and fan configuration to ensure efficient collection and removal of airborne substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is used to remove substances from air in the mist collector, then the removal efficiency of mist and chips is improved, but substances that pass through the filter accumulate and are discharged from the mist collector
Solution Approach 1:
The mist collector is divided into multiple functional zones: a filtration zone with a filter for removing substances, a collection zone with a drain for collecting substances that pass through the filter, and a discharge zone with a discharge port for removing accumulated substances. This segmentation allows the system to address both filtration effectiveness and prevention of substance accumulation simultaneously.
Solution Approach 2:
The drain mechanism extracts substances that have passed through the filter from the collection zone, separating them from the main air flow path. This extraction prevents accumulated substances from being discharged from the mist collector and returns them to the processing area for re-filtration.
2Object-generated harmful factors
If a drain mechanism is added to discharge substances that pass through the filter, then substance accumulation is prevented, but the device complexity increases
Solution Approach 1:
The drain and discharge port are integrated into the existing mist collector housing, merging the substance collection and discharge functions with the overall mist collector structure. This reduces the need for separate external components and minimizes the increase in device complexity while still preventing substance accumulation.
Solution Approach 2:
The mist collector is designed to perform multiple functions: filtration of airborne substances, collection of substances that pass through the filter, and discharge of accumulated substances. This multi-functionality is achieved by integrating the drain and discharge port into the existing structure, avoiding the need for entirely separate systems.
3Object-generated harmful factors
If substances are discharged from the mist collector to the outside, then accumulation is prevented, but the harmful factors increase in the surrounding environment
Solution Approach 1:
Instead of discharging substances that pass through the filter to the outside environment, the system converts this potentially harmful discharge into a beneficial circulation loop. The drain collects these substances and the discharge port returns them to the processing area, where they can be re-filtrated by the mist collector, thus preventing environmental contamination while still preventing accumulation.

AI summary
A machine tool includes: a body (130) including a processing area for a workpiece; an ejection part (125) configured to eject a coolant into the processing area; and a mist collector (40) configured to suck a substance included in air as a result of the coolant being ejected from the ejection part (125) into the processing area. The mist collector (40) includes a first filter (56) for removing the substance. The machine tool further includes: a drain (65) configured to discharge the substance that has passed through the first filter (56) to the body (130); and a suction mechanism (66) configured to suck the substance that has passed through the first filter (56) from the mist collector (40) into the drain (65).
