Grain Color Sorter Dust Filtering Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grain color sorters do not effectively remove dust from grains, which affects processing quality.
Innovation Solution
A grain color sorter with a filtering device that includes a hopper, drop tube, sleeve, ventilation duct, and filter cartridge, equipped with a fan and filter screen, which captures dust and improves grain quality by filtering air and dust before grains enter the sorting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a filtering device is added to the grain color sorter, then dust removal capability is improved, but device complexity increases
Solution Approach 1:
The filter cartridge is nested within the hopper structure, with the filter screen positioned inside the hopper body. The supporting piece is nested within the filter cartridge, and the pull rod passes through the filter cartridge wall. This nesting arrangement allows the filtering device to be integrated into the existing grain color sorter structure without requiring separate external components, thereby improving dust removal capability while minimizing the increase in overall device complexity.
Solution Approach 2:
The filter screen is designed as a detachable component that can be easily removed from the filter cartridge using the pull rod. This extraction design allows the filter screen to be taken out for cleaning or replacement without disassembling the entire filtering device or hopper structure, making maintenance simple while maintaining effective dust removal during operation.
2Object-affected harmful factors
If a filter screen is installed in the filter cartridge, then dust filtering effectiveness is improved, but ease of maintenance deteriorates
Solution Approach 1:
The pull rod is designed to enable easy manual removal of the filter screen from the filter cartridge. The supporting piece with the third through hole allows the pull rod to pass through and engage with the filter screen, enabling operators to easily extract the filter screen for cleaning or replacement by simply pulling the rod. This self-service design makes maintenance straightforward without requiring specialized tools or complex disassembly procedures.
Solution Approach 2:
The filtering system is segmented into distinct components: the filter screen, supporting piece, and filter cartridge. The filter screen is a separate, removable element that can be independently accessed and maintained. This segmentation allows the filter screen to be easily removed for cleaning while leaving the rest of the filtering device intact, significantly improving ease of maintenance while maintaining filtering effectiveness.
3Ease of operation
If the supporting piece is made movable within the filter cartridge, then ease of filter screen removal is improved, but device complexity increases
Solution Approach 1:
The supporting piece is designed as a simple, segmented structure with a third through hole that allows the pull rod to pass through. The supporting piece can move independently within the filter cartridge along the pull rod, enabling easy filter screen removal. This segmented design keeps the mechanism simple while achieving the desired ease of operation, as each component has a single, well-defined function without complex interconnections.
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 filtering device effectively reduces dust content in grains, enhancing processing quality by ensuring cleaner grains are sorted, and allows for easy removal of trapped dust.
Implementation Method 1
a fan is installed in the ventilation duct
Implementation Method 2
a filter screen is installed inside the filter cartridge, and the filter screen is installed at an end of the filter cartridge close to the opening
