Bulk Material Removal Device with Vertical Lifting Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulk material storage systems face inefficiencies in the removal process, particularly in achieving even emptying and accessing all areas of the storage space, especially when the storage space is closed or has flexible walls, and there is a need for automated and flexible handling of the removal head.
Innovation Solution
A removal device with a movable, flexible conveying pipe arrangement and an electromotive drive unit allows the extraction head to be raised and lowered vertically, and equipped with traversing means for automatic movement in a changeable curve or linear path, enabling efficient access to all areas of the storage space, including the ceiling, and includes traction means for guided movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the removal head is kept stationary at the bottom of the storage room, then the structure is simple, but the base area that can be processed is limited and emptying is uneven
Solution Approach 1:
The removal head is transformed from a stationary component to a mobile one, capable of vertical movement between the bulk material surface and a parking position in the ceiling area. This dynamic configuration allows the removal head to access different areas of the storage room by being lowered onto the bulk material surface, thereby increasing the processable base area without requiring a complex array of fixed removal heads throughout the storage space.
2Productivity
If lifting means are added to move the removal head vertically, then the processable base area increases, but the device complexity increases
Solution Approach 1:
The lifting means are designed to be integrated with the conveying pipe arrangement, utilizing the existing structural elements of the conveyor system to provide the lifting function. This self-service approach allows the conveying pipe arrangement to serve dual purposes: both material conveyance and vertical positioning of the removal head, thereby improving emptying efficiency while minimizing the addition of separate complex lifting mechanisms.
3Ease of repair
If the removal head can be raised to a parking position in the ceiling area, then access for maintenance is improved, but the device complexity increases
Solution Approach 1:
The removal head is given the capability to move in the vertical dimension, transitioning from operating at the bottom of the storage room to being raisable up to a parking position in the ceiling area. This vertical displacement provides easy access to the removal head for maintenance and inspection purposes, as technicians can readily reach the head when it is positioned near the ceiling, without requiring complex external access mechanisms or disassembly procedures.

Function Achieved in This Case
This solution enables efficient and even emptying of bulk materials, allows for easy access and maintenance of the extraction head, and increases the processable base area by allowing the removal head to be positioned strategically, promoting homogeneous emptying and reducing manual intervention.
