Slope Clearing System for Bulk Material Homogenization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of bulk materials with high clay content and moisture in industrial processes, such as cement production, becomes difficult due to lump formation and poor flow properties, making it challenging to remove and transport these materials efficiently, leading to increased effort and potential equipment failure.
Innovation Solution
A slope clearing system for circular mixed beds that uses a conveyor device attached to a vertical central column, with rotating conveyor elements that engage the end face of the bulk material heap, allowing for continuous removal and homogenization of the material by moving along the end face and adjusting the angle of the conveyor device to match the heap's geometry, thereby minimizing effort and preventing lump formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rake or reclaim boom is used to activate and remove bulk material, then the material can be removed from the stockpile, but the material tends to stick together and form lumps, requiring reactivation and increasing the effort needed
Solution Approach 1:
The conveyor device is made movable along the end face of the bulk material stockpile, allowing dynamic adaptation to the material's position and geometry. This enables continuous engagement with the material surface, preventing lump formation by constantly moving across different areas rather than staying fixed in one position.
Solution Approach 2:
The bulk material stockpile is processed by engaging multiple discrete conveyor elements along its end face. Each conveyor element independently engages and transports material, dividing the removal process into multiple parallel actions that collectively handle the entire material surface, reducing overall handling difficulty.
2Productivity
If additional conveying means are added to transport the bulk material, then the material transport capacity increases, but the device complexity increases
Solution Approach 1:
The conveyor device serves multiple functions simultaneously: it transports bulk material toward the central column, moves along the end face to engage different areas of the stockpile, and its circulating transport means continuously cycles the conveyor elements. This multi-functionality eliminates the need for separate conveying systems, maintaining productivity while reducing overall device complexity.
3Stability of the object's composition
If the conveyor device moves along the end face and engages the bulk material, then homogenization is achieved during extraction, but the angle of the conveyor device must be precisely adjusted to match the heap geometry
Solution Approach 1:
The conveyor device incorporates adjustable angling capability that allows dynamic adaptation to different stockpile geometries. This adjustability enables the conveyor to maintain optimal engagement angles across varying heap configurations, achieving consistent homogenization results without requiring complex fixed-angle mechanisms for each specific geometry.
Solution Approach 2:
The system allows modification of the conveyor device's angular parameter to match different stockpile geometries. By changing this key geometric parameter, the system adapts to various heap shapes and sizes, maintaining effective engagement and homogenization performance across different operating conditions without requiring complete redesign.
