Cyclone Drain Structure for Machining Fluid Defoaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing separation devices, such as anti-foaming liquid cyclones, are inadequate in effectively suppressing foaming of liquids after separating foreign matters, leading to inefficiencies in reusing machining fluids.
Innovation Solution
A defoaming structure for a separation device featuring a cyclone with a cylindrical member surrounding the discharge port, where the liquid and foreign matters are discharged downward through an opening portion, reducing the area where the liquid collides with the liquid level, thereby decelerating the flow and minimizing foaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a conventional cyclone separator is used to separate foreign matters from liquid, then separation function is achieved, but foaming of the liquid occurs and is not sufficiently suppressed
Solution Approach 1:
A cylindrical member is introduced as an intermediary structure between the discharge port and the liquid surface. This cylindrical member mediates the discharge process by guiding the liquid flow and preventing direct impact with the liquid surface, thereby suppressing foam generation while maintaining effective separation of foreign matters from the liquid
Solution Approach 2:
The invention uses a simple cylindrical member with an opening portion at the lower end, which is structurally simple and easy to manufacture. This straightforward design achieves the defoaming function without requiring complex mechanisms or additional chemicals, making it cost-effective and practical for industrial application
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively suppresses foaming, improving the separation accuracy and efficiency of foreign matter removal without the need for additional defoaming agents, enhancing the reuse of machining fluids.
Implementation Method 1
a swirling flow chamber which has a portion whose inner diameter gradually decreases in the direction of gravity and in which a liquid material to be separated supplied to a large-diameter portion of the inner diameter is swirled and separated into a substance with a high specific gravity and a liquid with a low specific gravity
Implementation Method 2
the liquid and the foreign matters discharged from the discharge port are discharged downward through the opening portion... reducing the area where the liquid collides with the liquid level, thereby decelerating the flow and minimizing foaming

AI summary
A defoaming structure of a separation device includes a cyclone including an introduction portion and a drain portion including a discharge port, and a cylindrical member surrounding the discharge port and extending downward from the discharge port. The drain portion includes a first member connected to the introduction portion, a second member connected to the first member and having a discharge port, and a first inner peripheral surface formed from the first member toward the second member and having an inner diameter decreasing downward.
