Aerodynamic Particle Separator Using Rotating Pinwheel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing particle separation apparatuses fail to effectively separate particles into two or more groups based on inertial and/or aerodynamic characteristic differences, lacking the ability to divert and remove a portion of particles from the stream without using screens or sieves, which limits their ability to produce a uniform distribution of particles by size, density, and other properties.
Innovation Solution
An apparatus with a separator component that utilizes inertial and/or aerodynamic characteristic differences to separate particles into two or more groups, featuring a rotating pinwheel and fins, and potentially an opening within the housing for diverting particles, allowing for the separation and potential recycling of particles based on their characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If screens or sieves are used to separate particles, then particle separation by size is improved, but device complexity and obstruction in main crossflow increase
Solution Approach 1:
The patent removes screens and sieves from the particle separation system entirely, extracting the obstruction element while maintaining separation functionality through alternative means (aerodynamic classification chamber that separates particles based on aerodynamic properties rather than physical screening)
Solution Approach 2:
The patent replaces the mechanical screening system with an aerodynamic classification system that uses air flow and inertial differences to separate particles, substituting mechanical contact-based separation with fluid dynamic-based separation
2Manufacturing precision
If screens or sieves are used to separate particles, then particle separation by size is improved, but productivity decreases due to obstructions in main crossflow
Solution Approach 1:
The patent removes screens and sieves from the particle separation system entirely, extracting the obstruction element while maintaining separation functionality through alternative means (aerodynamic classification chamber that separates particles based on aerodynamic properties rather than physical screening)
Solution Approach 2:
The patent employs pneumatic principles by using air flow through the classification chamber to separate particles based on their aerodynamic properties, utilizing gas-fluid dynamics rather than mechanical screening to achieve particle separation
3Ease of operation
If prior art apparatuses are used, then particle conveyance is achieved, but particle separation into distinct groups is not accomplished
Solution Approach 1:
The patent segments the particle stream into distinct groups based on aerodynamic properties by creating separate collection zones within the classification chamber, dividing the continuous particle flow into discrete particle populations with different characteristics
Solution Approach 2:
The patent changes the separation parameter from physical screening (size-based mechanical filtration) to aerodynamic properties (drag and inertial characteristics), using air flow dynamics to differentiate and separate particles based on their response to aerodynamic forces
