Ventilation system for storage covers and method of use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems for particulate piles covered by storage covers fail to provide adequate airflow distribution throughout the height of the pile, leading to issues like mold growth, moisture migration, and insect or rodent infestation.
Innovation Solution
Incorporating a vent system with a mesh layer and flap mechanism into the storage cover, allowing for improved airflow pathways from the top to the bottom of the pile, enhancing aeration efficiency and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fans are installed at the base of the particulate pile to create suction airflow, then air flow is generated at the base of the pile, but air flow does not distribute throughout the height of the pile
Solution Approach 1:
The patent introduces vertical dimension to airflow distribution by placing vents at the top of the pile (under the storage cover) rather than only at the base. This creates a three-dimensional airflow pathway that distributes air throughout the height of the particulate material, resolving the contradiction between generating airflow and distributing it effectively throughout the pile volume.
Solution Approach 2:
The aeration system is segmented into multiple airflow entry points: vents at the top of the pile and suction fans at the base. This segmentation allows air to be introduced at multiple locations simultaneously, creating comprehensive airflow distribution throughout the pile height rather than concentrating airflow at a single location.
2Quantity of substance
If aeration pipes are placed at the base and extend towards the center, then some air flow is achieved, but adequate air flow throughout the height of the particulate pile is not provided
Solution Approach 1:
The patent adds vertical airflow pathways by installing vents at the top of the pile (under the storage cover) in addition to base-level aeration pipes. This creates a vertical airflow dimension that penetrates through the entire height of the particulate material, dramatically improving aeration efficiency compared to horizontal pipe placement alone.
Solution Approach 2:
The system merges top-ventilation (through vents under the storage cover) with base-aeration (through suction fans and pipes) into a unified aeration system. This combination allows air to flow through the pile from both top and bottom simultaneously, maximizing airflow distribution and aeration efficiency throughout the entire pile volume.
3Object-affected harmful factors
If the storage cover is sealed to prevent weather intrusion, then protection from mold and moisture is improved, but airflow for aeration is restricted
Solution Approach 1:
The patent incorporates vents with mesh screens into the storage cover. The mesh material provides porosity that allows airflow through the cover while maintaining the protective seal against weather intrusion. This resolves the contradiction by enabling simultaneous air permeability for aeration and weather protection through the use of porous mesh material.
Solution Approach 2:
The mesh screen acts as an intermediary element between the sealed storage cover and the aeration requirement. It mediates the conflicting needs by allowing air molecules to pass through while blocking larger particles and weather elements, thus enabling both protection and airflow through a single integrated component.
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 vent system ensures more even and effective airflow through the particulate material, reducing the risk of mold, moisture, and pest infestation by distributing air throughout the pile, not just at the base.
Implementation Method 1
a mesh layer removably attached to said vent body wherein said mesh layer is movable from an attached to a detached position and wherein when said mesh layer is in said attached position, said mesh layer at least partially covers said vent body
Implementation Method 2
a flap attached to said vent body wherein said flap is movable from an opened position to a closed position and wherein when said flap is in said closed position, said flap covers said mesh layer
Implementation Method 3
Aeration requires a mechanical system that moves air through the particulate pile. A common aeration method in particulate piles covered by a storage cover is to use fans installed at the base of the particulate pile to create suction airflow underneath the storage cover
