Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compact dedusting apparatuses face limitations in capacity and efficiency due to air velocity and product carryover issues, requiring a more compact design that maintains or improves cleaning efficiency.
Innovation Solution
A compact dedusting apparatus with a double wash deck configuration, enhanced air flow through the Venturi zone, and strategically positioned air outlets to minimize product carryover, utilizing a magnetic flux field to neutralize static charge and fluidize particles, with air flow directed from the back of the housing to the Venturi panel to increase cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air velocity is increased to improve cleaning efficiency, then contaminant removal improves, but product carryover increases
Solution Approach 1:
The patent introduces a vertical dimension to air flow by incorporating a lower air outlet that discharges air downward, complementing the traditional upper outlet. This multi-directional air flow approach allows effective contaminant removal without excessive horizontal air velocity that would cause product carryover
Solution Approach 2:
The air discharge function is segmented into two separate outlets: an upper air outlet for general contaminant removal and a lower air outlet positioned below the wash deck for targeted dust particle discharge. This segmentation allows optimized air flow paths for different contaminant types without compromising product integrity
2Volume of moving object
If compact design is implemented to reduce apparatus size, then space requirements decrease, but cleaning capacity may be reduced
Solution Approach 1:
The patent utilizes vertical space by positioning the lower air outlet below the wash deck and directing air flow downward. This vertical dimension exploitation allows compact horizontal footprint while maintaining adequate air flow paths and cleaning capacity
Solution Approach 2:
The lower air outlet and associated air flow path are nested within the compact housing structure below the wash deck level. This nested arrangement accommodates the additional air flow path without increasing the overall apparatus envelope, maintaining compactness while enhancing cleaning capacity
3Device complexity
If single wash deck configuration is used to simplify design, then device complexity decreases, but cleaning capacity is limited
Solution Approach 1:
The cleaning function is segmented into two separate wash decks: a primary wash deck for initial contaminant removal and a secondary wash deck for final cleaning. This segmentation increases overall cleaning capacity while keeping each individual wash deck relatively simple in design

AI summary
A compact housing for a dedusting apparatus utilizes a magnetic flux field to disrupt the static charge attracting dust particles to product particles, which along with fluidization and counter current airflow principles that are proven to dislodge dust particles from the product, provides a highly efficient, compact deduster. The housing supports a double wash deck with product flow separated between the back-to-back primary wash decks. A deflector directing the flow of product onto the primary wash decks is provided with an extension that extends parallel to the wash deck to eliminated product bouncing off of the wash deck. The lower air outlets are eliminated, while the upper air outlets are positioned in extensions to the main housing above the product inlet opening. Air flow through the Venturi zone is enhanced by re-directing clean air directly to the backside of the Venturi panels, thereby eliminating the extraneous by-pass boxes.
