Rotating Screening Basket with Adjustable Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screening buckets require multiple baskets or lengthy operations to achieve fractionated screening, leading to high costs and material loss due to the need for multiple baskets and frequent shutdowns for basket changes.
Innovation Solution
A rotating screening basket with adjustable screening capabilities, featuring a first and second cylindrical body with overlapping holes, allowing for continuous adjustment of screening sizes without the need for multiple baskets, utilizing a hydraulic actuating unit for axial and rotational movement to change the filtering capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple baskets with different hole dimensions are used to achieve fractionated screening, then the screening capability is improved, but the device complexity and cost increase
Solution Approach 1:
The basket is segmented into two independent cylindrical bodies (first and second cylindrical bodies), each with its own set of holes. These segmented bodies can be independently positioned and rotated to create variable screening configurations, eliminating the need for multiple complete baskets while maintaining fractionated screening capability.
Solution Approach 2:
The basket structure is made dynamic through the ability to independently rotate and position the first and second cylindrical bodies relative to each other. This dynamic adjustment allows continuous variation of the effective hole size by changing the overlapping degree between the two bodies, providing adaptability without requiring multiple fixed baskets.
2Adaptability or versatility
If basket replacement is performed to change screening size, then the adaptability is improved, but the loss of time increases
Solution Approach 1:
The basket employs dynamic adjustment mechanisms that allow the first and second cylindrical bodies to be rotated and repositioned during operation. This enables continuous screening size adjustment without stopping the excavating process, completely eliminating the shutdown time associated with basket replacement in conventional systems.
Solution Approach 2:
A single basket structure integrates multiple screening functions by combining two cylindrical bodies with adjustable relative positions. This universal design allows the same basket to perform multiple screening sizes through internal adjustment, replacing the need for multiple specialized baskets that would require sequential replacement.
3Device complexity
If a single basket with fixed hole size is used, then the device complexity is reduced, but the adaptability decreases
Solution Approach 1:
The basket is divided into two independent cylindrical bodies with各自 sets of holes, allowing each segment to contribute to the overall screening function. This segmentation enables variable configuration while maintaining a relatively simple structure compared to using multiple complete baskets.
Solution Approach 2:
The first and second cylindrical bodies are nested within each other, with one body positioned inside the other. This nested configuration allows both bodies to be housed within a single basket structure, achieving adaptability through internal arrangement rather than through multiple external baskets.
