Centrifuge Flow Interference Member for Homogeneous Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centrifuges face challenges in continuously discharging product streams with suspended solids, as high G-forces can cause secondary separation, leading to stagnation and uneven particle distribution, which affects the homogeneity and continuous operation of the process.
Innovation Solution
Incorporating discrete, flow interference members in the product stream pathways disrupts the flow, preventing secondary separation and maintaining a uniform mixture of solids, allowing for continuous and homogeneous discharge of the second product stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high G-forces are applied in the centrifuge to separate the feed stream, then separation efficiency is improved, but secondary separation occurs causing non-uniform particle distribution and stagnation
Solution Approach 1:
The patent introduces flow interference members that create controlled turbulence and flow disruption in the product stream pathway. This mechanical disturbance prevents particles from settling and stagnating during discharge, maintaining uniform particle distribution while allowing high G-force separation to continue effectively
Solution Approach 2:
The flow interference members act as intermediary elements between the high G-force separation zone and the product discharge pathway. These members mediate the flow dynamics by disrupting laminar flow patterns that cause secondary separation, while allowing the centrifugal separation process to remain efficient
2Productivity
If continuous discharge is attempted without flow disruption, then productivity is maintained, but homogeneity of the product stream deteriorates due to secondary separation
Solution Approach 1:
The flow interference members create continuous flow disruption and turbulence in the product stream pathway, preventing particle settling and aggregation during continuous discharge. This maintains product homogeneity while enabling uninterrupted operation
Solution Approach 2:
The patent enables continuous discharge operation by incorporating flow interference members that prevent secondary separation throughout the discharge process. The useful action of continuous product removal is maintained without the need for periodic interruptions to restore homogeneity
3Stability of the object's composition
If flow interference members are added to disrupt secondary separation, then product homogeneity is improved, but device complexity increases
Solution Approach 1:
The centrifuge interior is segmented into distinct functional zones: the separation zone where high G-forces act on the feed stream, and the product stream pathway where flow interference members are placed. This segmentation allows the disruption function to be isolated to specific locations without complicating the entire centrifuge structure
Solution Approach 2:
The flow interference members are strategically positioned only in the product stream pathway where flow disruption is needed, rather than throughout the entire centrifuge. This localized application of flow interference minimizes structural complexity while achieving the desired homogeneity improvement

Function Achieved in This Case
This approach ensures a uniform and continuous discharge of the second product stream with improved homogeneity, reducing the need for frequent desludging and minimizing wear on the centrifuge, thereby prolonging operational stability and maintaining consistent product characteristics.
Implementation Method 1
a centrifuge having a central axis of rotation... separating at least one feed stream into at least two product streams
Implementation Method 2

AI summary
The present disclosure relates to disrupting a flow of a product stream in a centrifuge to help keep the contents of the stream mixed in a relatively homogenous manner. For example, a centrifuge can include at least one discrete, flow interference member located in a product stream pathway to disrupt the flow of the product stream.
