Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coolant cleaning systems struggle to efficiently remove finer particles from high-flow machining processes due to limitations in fluid reservoir size and the effects of viscosity and surface tension, leading to suspended particles that compromise machining accuracy and efficiency.
Innovation Solution
A magnetic drum system that rotates partially in the dirty fluid, attracting ferritic particles and depositing them on its surface, combined with disc screen filters and spray-back nozzles to agglomerate and remove particles, along with a dynamic seal to prevent fluid bypassing, enhances particle separation and collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional gravity-based separation systems are used, then larger chips and particles can be removed, but finer particles remain suspended in the coolant
Solution Approach 1:
The patent replaces gravity-based mechanical separation with magnetic field-based separation. A magnetic drum or magnetic plates create a magnetic field that attracts and captures ferrous particles of all sizes, including fine particles that gravity cannot effectively separate. This substitution of the separation mechanism resolves the contradiction by enabling both high removal efficiency and coolant cleanliness simultaneously.
Solution Approach 2:
The patent changes the separation parameter from gravitational force to magnetic force. By introducing magnetic fields as the separation mechanism, the system can capture particles based on magnetic susceptibility rather than size and weight, allowing effective removal of fine ferrous particles that were previously impossible to separate with gravity-based systems.
2Productivity
If high flow rates are used for machining, then heat and chips are removed effectively, but finer particles remain suspended due to viscosity and surface tension
Solution Approach 1:
The patent replaces hydrodynamic separation (which fails at high flow rates due to viscosity and surface tension) with magnetic field-based separation. The magnetic drum or plates create a stationary magnetic field that captures particles regardless of fluid flow velocity, allowing high coolant flow rates to be maintained while achieving effective particle separation.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary mechanism between the coolant flow and particle separation. The magnetic field acts as a mediator that captures ferrous particles from the high-velocity coolant stream, bypassing the limitations of direct hydrodynamic separation and enabling both high productivity and particle removal effectiveness.
3Manufacturing precision
If magnetic drums are used to capture particles, then particle removal effectiveness increases, but the system complexity increases
Solution Approach 1:
The patent extracts the magnetic separation function from a complex integrated system and implements it as a standalone magnetic drum or magnetic plates. This modular approach captures particles effectively while keeping the overall system relatively simple, as the magnetic component can be added to existing coolant filtration systems without requiring complete system redesign.

AI summary
Coolant fluid cleaning method, system, and apparatus use a rotating magnet to remove particulate matter from a fluid used to cool or lubricate a machining or other operation. Such system includes a rotating magnet in fluid communication with apparatus circulating fluid past the rotating magnet. A scraper blade removes particulate matter which is picked up by the rotating magnet. The system or apparatus can include a dirty fluid reservoir, one or more conveyor which removes chips and particulate matter from the dirty fluid reservoir, and a clean fluid reservoir. The rotating magnet collects particulate matter in the dirty fluid reservoir and discharges the collected particulate matter to a discharge conveyance. When the rotating magnet is used in combination with a disc filter, the magnet relieves some cleaning load from the disc filter.
