Cutting Fluid Circulation Channel Layout to Prevent Sludge Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting fluid circulation devices require complex configurations and manual maintenance, leading to inefficiencies in filtering and reusing cutting fluid, which can result in deposition and retention of foreign substances, potentially causing machine tool failures.
Innovation Solution
A cutting fluid circulation device with a primary filter, secondary filter, tertiary filter, and pumps that utilize a network of channels with narrowing widths to enhance flow velocity and prevent deposition, along with a switching unit to manage fluid flow between tanks, allowing for efficient filtration and reuse without auxiliary nozzles or excessive pumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple pumps and agitating nozzle bodies are used to suppress deposition and retention of foreign substances, then the effectiveness of suppressing deposition is improved, but the device complexity and cost increase
Solution Approach 1:
The connecting channel is designed with a narrowing width from upstream to downstream, enabling the cutting fluid flow to automatically suppress deposition of foreign substances without requiring auxiliary agitating nozzle bodies or additional pumps. The flow dynamics self-regulate to prevent sludge accumulation.
Solution Approach 2:
The channel width parameter is changed along the flow direction, narrowing from upstream to downstream. This geometric parameter change creates increased flow velocity and shear stress that effectively suppresses deposition of foreign substances without additional mechanical components.
2Reliability
If the channel width is narrowed to increase flow velocity and suppress deposition, then the effectiveness of preventing foreign substance retention is improved, but the manufacturing complexity increases
Solution Approach 1:
The connecting channel has different width characteristics at different locations: wider at the upstream end near the filtration tank and narrower at the downstream end near the pumping-up tank. This local quality variation optimizes flow velocity distribution to prevent deposition without requiring complex overall structure.

Function Achieved in This Case
The device effectively suppresses the deposition and retention of foreign substances with a simplified configuration, ensuring continuous operation and reducing the risk of machine tool failures by maintaining fluid flow and filtration efficiency.
Implementation Method 1
The connecting channel has an identical channel width along an entire length thereof, or at least a portion of the channel width is narrowed stepwise or continuously from the filtration tank to the pumping-up tank

AI summary
A cutting fluid circulation device includes a first tank reservoir, a primary filter, and a first pump. The tank reservoir stores cutting fluid discharged from a machine tool. The primary filter is provided in the first tank reservoir and filters the cutting fluid. The first pump pumps up the cutting fluid filtered by the primary filter in the first tank reservoir. The first tank reservoir is partitioned into a filtration tank in which the primary filter is disposed, a pumping-up tank in which the first pump is disposed, and a connecting channel in which the cutting fluid in the filtration tank is allowed to flow into the pumping-up tank. The connecting channel has an identical channel width along an entire length thereof, or at least a portion of the channel width is narrowed stepwise or continuously from the filtration tank to the pumping-up tank.
