Oil-Water Separation Device With Inclined Guide Partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oil-water separation devices face issues where lubricating oil accumulates and stagnates, leading to deterioration and abnormal odors due to its low specific gravity causing it to float and spread away from discharge ports, resulting in inefficient separation and discharge.
Innovation Solution
The oil-water separation device features a separation container divided into two chambers with a lower partition plate and an upper partition plate that includes a guide section, preventing lubricating oil from entering the coolant chamber and ensuring efficient separation and discharge by guiding lubricating oil to its designated chamber while allowing coolant to pass through a communication section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the communication section is formed at the bottom part of the separation container, then the coolant can be discharged efficiently, but the lubricating oil accumulates and stagnates causing deterioration and abnormal odor
Solution Approach 1:
The partition plate is divided into a lower partition plate and an upper partition plate, creating separate flow paths for coolant and lubricating oil. The lower partition plate prevents mixed liquid from directly entering the second chamber, while the upper partition plate with its guide section directs lubricating oil to the first chamber. This segmentation resolves the contradiction by enabling efficient coolant discharge through the communication section while preventing lubricating oil stagnation.
Solution Approach 2:
Different regions of the partition plate are given different functions: the lower partition plate serves as a barrier to prevent direct entry of mixed liquid, while the upper partition plate's guide section specifically guides lubricating oil. This local differentiation of function allows the system to simultaneously achieve efficient coolant discharge and prevent lubricating oil accumulation, resolving the technical contradiction.
2Volume of moving object
If the separation container is made small to save space, then the device is compact, but the separation efficiency may be reduced
Solution Approach 1:
The partition plate extends in the vertical dimension with both lower and upper sections, utilizing the depth direction to create effective separation. This vertical arrangement allows the compact separation container to achieve efficient separation by leveraging the third dimension (depth) rather than requiring a large horizontal footprint, thus resolving the contradiction between compact size and separation efficiency.

Function Achieved in This Case
This configuration enables efficient separation and discharge of lubricating oil and coolant, preventing stagnation and odor generation, even in a small separation container, while maintaining a space-saving design that does not interfere with machine tools.
Implementation Method 1
the mixed liquid is composed such that the coolant with a high specific gravity settles at the bottom while the lubricating oil with a low specific gravity floats up on the liquid surface
Implementation Method 2
the lubricating oil that attempted to pass over the lower partition plate and enter the second chamber is guided to the first chamber by the guide section of the upper partition plate at a position where the lubricating oil floats up due to the low specific gravity
Implementation Method 3
the coolant with a high specific gravity moves from the first chamber to the second chamber through the communication section
