Solution Overview
Problem
Existing bulk material removal devices for stores, such as wood pellet stores, face challenges in safe and convenient operational management, often causing material stress and undesirable side effects like dust formation and increased fines fractions due to passive removal methods.
Innovation Solution
A removal device with independently driven and controlled drive elements, allowing for precise and flexible movement of the removal head, which can move in various directions and control the dosing of bulk material, reducing material stress and minimizing friction, using a combination of drive rollers and a suction unit with a movable suction device and sensor systems for coordinated operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If passive removal methods are used where bulk material slips to a stationary removal head, then the removal device structure is simple, but the bulk material experiences high stress and friction causing dust formation and increased fines fractions
Solution Approach 1:
Instead of having a stationary removal head and allowing bulk material to slip passively to it, the invention inverts the approach by making the removal head actively move through the bulk material to reach different removal points. This active removal method reduces material stress and friction while achieving the same removal function.
Solution Approach 2:
The removal head is transformed from a stationary component to a dynamic one equipped with multiple independently controllable drive elements. This enables the removal head to move in various directions (longitudinal, lateral, vertical) through the bulk material, reducing stress and dust formation while maintaining removal efficiency.
2Reliability
If a stationary removal head is used with passive material flow, then the device is easier to operate, but the bulk material undergoes undesirable changes including increased dust and fines
Solution Approach 1:
The invention reverses the traditional passive removal concept by implementing an active removal head that moves through the bulk material. This ensures consistent gentle handling of the material regardless of heap configuration, maintaining material quality while providing automated control through multiple drive elements.
3Adaptability or versatility
If multiple independently driven drive elements are used for precise removal head movement, then the removal flexibility and precision are improved, but the device complexity increases
Solution Approach 1:
The drive system is segmented into multiple independently controllable drive elements (first, second, and third drive elements) that can be controlled separately. This segmentation enables precise control of the removal head in different directions (longitudinal, lateral, vertical) while maintaining the ability to handle various bulk material configurations and removal requirements.
