Roller Press Frame Head Detachable Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller press machine frames are heavy and require significant space, becoming unstable when opened for maintenance, which increases downtime and transportation challenges due to the need for wide and heavy crossbeams to support high forces during high-pressure comminution.
Innovation Solution
A machine frame design with a detachable head piece and crossbeam that is independent of the closure, allowing for easier assembly and reduced weight, where the crossbeam is only responsible for supporting forces during operation, and the head-side elements are completely removed during disassembly, simplifying the construction and reducing the overall weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the machine frame is designed to be stable when opened for maintenance, then the frame structure must be reinforced or upper belts removed, but this increases the weight and complexity of the machine frame
Solution Approach 1:
The machine frame is divided into separate functional components: the main frame structure and the head closure element. The head closure element can be completely removed during maintenance, while the main frame remains stable due to its inherent structural design with crossbeams and lateral supports that do not require the head closure for stability.
Solution Approach 2:
The head closure element is extracted as a separate removable component from the main frame structure. This allows the head closure to be completely removed during maintenance without affecting the structural integrity or stability of the main frame, eliminating the need to remove upper belts or reinforce the frame for stability during opened state.
2Strength
If the crossbeam is designed to support high forces during operation, then the crossbeam must be heavy and reinforced, but this increases the overall weight and space requirement of the roller press
Solution Approach 1:
The support function is segmented between the crossbeam (for operational load-bearing) and the head closure element (for structural completeness during operation). The crossbeam can be optimized purely for its load-bearing function during operation without needing to also support the head closure element's weight, reducing its required weight and dimensions.
Solution Approach 2:
The structural configuration of the machine frame is dynamically adjusted between operational state and maintenance state. During operation, the head closure element is in place and the crossbeam supports both operational forces and the closure element's weight. During maintenance, the closure element is removed and the crossbeam only needs to support operational forces, allowing for optimization of its design.
3Ease of operation
If the head element is suspended in a pendulum manner and pivoted to the side for opening, then the machine frame can be opened, but this increases the complexity of the opening mechanism and the width of the roller press
Solution Approach 1:
The head closure element is completely extracted (removed) from the machine frame during maintenance instead of being pivoted or moved to the side. This eliminates the need for complex pendulum suspension mechanisms and lateral movement arrangements, reducing the width requirement of the roller press while maintaining full opening capability for maintenance.
Solution Approach 2:
The head closure element is segmented as a completely separate removable component rather than being integrated into the frame structure requiring mechanical connection mechanisms. This allows for simple removal and reattachment without complex opening mechanisms, reducing both the width requirement and mechanical complexity.
4Ease of operation
If the head-side elements are pushed to the side within the gate during opening, then the machine frame can be opened, but this requires a wider crossbeam and increases the space requirement
Solution Approach 1:
The head-side closure elements are completely extracted (removed) from the machine frame during maintenance operations. This eliminates the need for lateral movement mechanisms that would push these elements to the side within the gate, allowing for a more compact crossbeam design and reducing the overall width requirement of the roller press.
