Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for treating slurry from mechanical operations, such as lathing and milling, face challenges in ecological, economical, and safety aspects due to inefficient separation and recycling of coolant fluids containing solid particles, particularly in fine working with precious materials like nickel, where perfect separation and recovery of valuable swarf are necessary.
Innovation Solution
A compact filtering and compacting device with a tubular container, hinged bottom, sieve filtering elements, and pressurization means for efficient separation and recycling of slurry, combined with a filtration chamber and compacting chamber, and a washing mechanism using a rotating U-shaped element for effective filtration and recovery of liquids and solid particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional filtering means are used for slurry treatment, then separation of liquid and solid particles is achieved, but the separation is not perfect and complete
Solution Approach 1:
The device is divided into two distinct chambers: a filtration chamber for liquid separation and a compacting chamber for solid particle compression. This segmentation allows each chamber to specialize in its function, achieving complete separation while maintaining manageable complexity through modular design
Solution Approach 2:
The filtration chamber is positioned above the compacting chamber within the same tubular container structure. The solid particles filtered in the upper chamber are automatically compacted in the lower chamber, creating a nested functional arrangement that achieves complete separation without requiring separate external systems
2Productivity
If multiple separate devices are used for filtering and compacting slurry, then functional efficiency is improved, but device complexity and space requirements increase
Solution Approach 1:
The filtration chamber and compacting chamber are merged into a single integrated device with a shared tubular container structure. The filtration chamber (31) and compacting chamber (32) work in sequence within the same housing, combining multiple functions into one compact unit that maintains high productivity while reducing overall system complexity
Solution Approach 2:
The tubular container structure serves multiple functions: it houses both the filtration and compacting chambers, provides structural support, and enables the sequential processing of slurry. This multi-functionality allows the device to achieve high productivity without requiring separate specialized components for each function
3Volume of moving object
If a compact design is used for the filtering device, then space requirements are reduced, but the separation efficiency may be compromised
Solution Approach 1:
The device utilizes vertical stacking of chambers within the tubular container, arranging the filtration chamber above the compacting chamber in the vertical dimension. This vertical arrangement achieves complete separation efficiency while maintaining a compact horizontal footprint, as the processing occurs along the vertical axis of the tubular structure
