Coolant Tank Flow Layout for Automatic Sludge Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coolant treatment devices for machine tools require manual cleaning to remove sludge or chips from the tank, which is time-consuming and labor-intensive.
Innovation Solution
A coolant treatment device with a first tank and a first pipe, featuring three coolant discharge portions: one producing a swirling flow on the tank's peripheral edge, another facing it across the central region, and a third discharging coolant diagonally downward to create turbulence and collect sludge into the first pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning is used to remove foreign matter from the tank, then the tank can be cleaned, but considerable time and effort are required
Solution Approach 1:
The system uses the coolant's own flow to transport foreign matter automatically. The coolant discharged from discharge ports creates flow patterns that move sludge and chips toward the suction port, enabling the system to clean itself without manual intervention
Solution Approach 2:
The invention utilizes hydraulic flow of coolant to transport foreign matter. By controlling the discharge of coolant from multiple ports, the system creates appropriate flow patterns that move debris toward the suction port, replacing manual mechanical cleaning with fluid-based transport
2Productivity
If coolant discharge portions are added to create swirling flow and turbulence, then foreign matter discharge efficiency is improved, but device complexity increases
Solution Approach 1:
The coolant discharge portions serve multiple functions: they create swirling flow to move foreign matter toward the center, generate turbulence to prevent deposition, and direct coolant flow toward the suction port. This multi-functionality reduces the need for separate cleaning mechanisms
Solution Approach 2:
The invention changes the flow parameters of the coolant by discharging it from multiple ports at different locations and angles. This creates varying flow patterns (swirling flow near walls, turbulence in central region) that effectively transport foreign matter without requiring additional mechanical components
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
The device efficiently discharges foreign matter like sludge or chips from the tank by utilizing the swirling flow and turbulence created by the coolant discharge portions, reducing the need for manual cleaning.
Implementation Method 1
a first coolant discharge portion that is disposed above the peripheral edge region and discharges the coolant such that a swirling flow of the coolant is produced on the peripheral edge region
Implementation Method 2
a third coolant discharge portion that is disposed above the peripheral edge region and discharges the coolant in a direction which is directed from the peripheral edge region toward the central region

AI summary
A coolant treatment device includes: a first tank having a bottom portion; a first pipe that is connected to the bottom portion; a first coolant discharge portion that discharges a coolant such that a swirling flow of the coolant is produced on a peripheral edge region of the bottom portion; a second coolant discharge portion that is provided at a position where the second coolant discharge portion faces the first coolant discharge portion across a central region of the bottom portion in a top view, and that discharges the coolant such that a swirling flow of the coolant is produced on the peripheral edge region; and a third coolant discharge portion that discharges the coolant in a direction which is directed from the peripheral edge region toward the central region and which avoids an opening of the first pipe in the central region in a top view.
