Multi-Stage Air Cleaning Machine Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning methods for agricultural products and other materials often leave behind debris due to the need for multiple passes through a single air cleaning machine or the use of separate machines, which increases processing time and costs.
Innovation Solution
A two-stage air cleaning machine with multiple air cleaners in a single unit, allowing for a single pass of the product through multiple stages of air cleaners with adjustable air velocity, enhancing debris removal and reducing the need for additional processing or separate machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single air cleaning machine is used, then the machine footprint is reduced, but the cleaning effectiveness decreases and debris remains in the final product
Solution Approach 1:
The air cleaning machine is divided into multiple independent air cleaning stages (first air cleaner, second air cleaner, etc.) arranged in sequence. Each stage has its own air knife and air leg, allowing progressive removal of debris in multiple passes through the same machine footprint, thereby maintaining compact size while improving cleaning effectiveness.
Solution Approach 2:
Instead of expanding the machine horizontally with multiple separate units, the patent stacks air cleaning stages vertically or arranges them in a compact sequence within the same footprint. This dimensional reorganization allows multiple cleaning operations to occur within a reduced horizontal area while maintaining effective debris removal.
2Manufacturing precision
If multiple separate air cleaning machines are used, then cleaning effectiveness improves, but processing time increases and costs increase
Solution Approach 1:
Multiple air cleaning stages that would traditionally require separate machines are merged into a single integrated machine. The product flows sequentially through multiple air cleaners in one continuous operation, achieving the cleaning effectiveness of multiple machines while eliminating the time and cost associated with transferring material between separate units.
Solution Approach 2:
The single air cleaning machine performs multiple cleaning functions through its multiple stages, making it a universal device that can handle various cleaning requirements in one pass. This multi-functionality eliminates the need for separate specialized machines and reduces overall processing time.
3Device complexity
If a single air cleaner is used, then device complexity is reduced, but the ability to remove different types of debris decreases
Solution Approach 1:
The air cleaning system is segmented into multiple independent stages, each with its own air knife and adjustable air velocity settings. This segmentation allows each stage to be optimized for removing different types of debris while maintaining a relatively simple overall device structure that builds upon the basic air cleaner design.
Solution Approach 2:
Each air cleaner stage features adjustable air velocity, allowing the system to dynamically adapt to different debris types and product characteristics. This dynamic adjustability enhances versatility without significantly increasing device complexity, as the same hardware can be reconfigured for different cleaning scenarios.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The two-stage air cleaning machine effectively removes debris and reduces processing time and costs by achieving a purer final product with a reduced machine footprint, suitable for a wide range of materials with varying bulk densities and geometries.
Implementation Method 1
removing debris or other foreign material with a lighter bulk density/weight from a product with a heavier bulk density/weight
Implementation Method 2
pass product through the airflow to remove lighter product, which is carried away by the airflow, leaving behind a cleaned product
Implementation Method 3
the heavier components are generally the desired final product and the lighter products or debris are often undesirable

AI summary
An assembly for cleaning material from a flowable product includes multiple stages of air cleaning for a product. Each air cleaning stage includes a vertical air column, an air knife, and at least one airlock. After introducing a product into the air column, the air knife disturbs material from the product and the material is carried away by the vertical air column. The airlock prevents significant disturbance of the vertical air column during operation. The cleaned product is delivered after a single cycle through the assembly having passed through several stages of cleaning.
