Solution Overview

Problem

Current oil-water separation technologies are inadequate for effectively removing oil from contaminated metalworking fluids and wastewater, as they lack efficiency and visibility of oil collection, making it difficult to monitor and manage oil separation in industrial settings.

Innovation Solution

A transparent or translucent oil-water coalescing separator with a coalescing chamber containing oil coalescing media, allowing visual detection of the oil collection band and enabling efficient separation and recycling of tramp oil, utilizing a prefilter and porous packing for enhanced separation efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional opaque separators are used, then the separation process is hidden from view, but it becomes difficult to monitor oil collection and manage separation efficiency

Engineering Contradiction:
Improvemonitoring oil collectionVSAvoidvisibility of oil collection band
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The separator incorporates transparent or translucent panels that allow visual detection of the oil collection band. The transparency enables the oil band to be seen through the panel, providing real-time monitoring capability without requiring additional sensors or indicators. This directly addresses the monitoring difficulty while maintaining the separation function.

Inventive Principle:
Principle #32Color changes

2Productivity

If manual intervention is used for oil removal, then the system is simple in structure, but operational efficiency decreases and labor requirements increase

Engineering Contradiction:
Improveoperational efficiencyVSAvoidmanual intervention requirement
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The separator enables operators to visually monitor the oil collection band and determine when oil removal is needed, allowing the system to signal its own maintenance requirements. This self-monitoring capability improves operational efficiency by eliminating the need for continuous manual checking while still using simple mechanical removal mechanisms.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If opaque materials are used for the separator body, then manufacturing is easier and materials are more durable, but visual monitoring of separation efficiency is impossible

Engineering Contradiction:
Improveseparation efficiency monitoringVSAvoidtransparent panel fabrication
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The separator uses transparent or translucent panels in place of opaque materials. These panels allow light to pass through, making the oil collection band visible from the outside. While transparent materials may have slightly different manufacturing requirements, they provide the critical function of enabling visual monitoring of separation efficiency.

Inventive Principle:
Principle #32Color changes

AI summary

An oil water coalescing separator has a coalescing chamber containing oil coalescing media. The separator is preferably substantially transparent so that the thickness of the band of coalesced tramp oil can be visually discerned at a glance. The separator preferably has a magnet base so the separator can be hung on a machine off the floor. The separator is also removable from the magnet base.
