Solution Overview
Problem
Existing methods for phase separation are not suitable for removing particulate contaminants from fluids, particularly in applications like vibratory grinding where high dirt concentrations occur with low volume flow.
Innovation Solution
A device with a receptacle divided into sedimentation and filtration areas, using a filter that surrounds a partition to separate particles by size, allowing for efficient sedimentation and filtration of fluids with low volume flow, enabling the reuse of cleaned fluids and reduction of waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phase separation is used to separate fluid mixtures, then separation of liquid phases is achieved, but particulate impurities cannot be removed
Solution Approach 1:
The device divides the receiving vessel into two distinct functional areas: a sedimentation area for removing particulate impurities and a filtration area for further particle separation. This segmentation allows the system to handle both liquid-phase separation and particulate removal, resolving the contradiction between phase separation capability and particulate removal applicability.
2Productivity
If conventional filtration is used to remove particles, then particle removal is achieved, but low volume flow rates cannot provide sufficient separation time
Solution Approach 1:
The sedimentation area performs preliminary separation of particulate impurities from the fluid mixture before the filtrate enters the filtration area. By allowing particles to settle under gravity in the sedimentation area first, the system achieves effective particle removal even at low volume flow rates, as particles are given sufficient time to separate before reaching the filter.
3Reliability
If multiple separate devices are used for sedimentation and filtration, then complete particle removal is achieved, but device complexity increases
Solution Approach 1:
The device merges the sedimentation area and filtration area into a single integrated receiving vessel, with the partition separating the two functional areas and the filter surrounding the partition. This combination achieves complete particle removal through both sedimentation and filtration while avoiding the complexity of multiple separate devices, as both functions operate within one unified structure.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively separates particulate contaminants from fluids, allowing for the reuse of cleaned fluids and minimizing waste, particularly in vibratory grinding processes, while maintaining low environmental impact.
Implementation Method 1
separating particles of a predetermined size by means of sedimentation; by allowing the particles sufficient time during separation to separate from the fluid itself through sedimentation, i.e., by precipitation from the fluid under the influence of gravity
Implementation Method 2
separating smaller particles by means of filtration; Smaller and therefore lighter particles, on the other hand, can then be completely removed from the fluid stream by filtration
