Movable Roller Press Force Generation Device

Solution Overview

Problem

Existing roller press systems face significant downtime and safety concerns during maintenance and replacement of heavy force generation devices, which are difficult to access due to their placement under the top frame, leading to inefficient maintenance processes.

Innovation Solution

A roller press design with a frame assembly that allows top members to be selectively separated from side members, enabling the force generation device to be movably attached using a connection device such as a hinge or sliding mechanism, allowing for removal without rotating the entire frame, thus facilitating easier access and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If force generation devices are placed under the top frame of the roller press, then the pressing force is uniform and the system is protected against overloading, but the devices become heavy and difficult to remove for maintenance

Engineering Contradiction:

Improvesystem protection against overloadingVSAvoidaccessibility of force generation device

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The frame assembly is divided into separable components: top members, side members, and bottom members that can be selectively disconnected. This segmentation allows the top members to be removed independently, providing access to the force generation devices without requiring rotation or disassembly of the entire frame structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection devices (hinges or sliding mechanisms) enable dynamic movement of the force generation devices between a fixed operational position and a removed/maintained position. This dynamic capability allows the devices to be easily accessed for maintenance while maintaining structural integrity during operation.

Inventive Principle:

Principle #15Dynamics

2Ease of repair

If the entire overhead frame is rotated into the open position to access force generation devices, then the devices can be removed for maintenance, but significant space is occupied and safety concerns arise

Engineering Contradiction:

Improveaccessibility of force generation deviceVSAvoidsafety concerns during maintenance

Core Design Contradiction:

Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The frame assembly is divided into separable components: top members, side members, and bottom members that can be selectively disconnected. This segmentation allows the top members to be removed independently, providing access to the force generation devices without requiring rotation or disassembly of the entire frame structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The top members are extracted as separate removable components from the frame assembly. This extraction allows direct access to the force generation devices without rotating the overhead frame, eliminating the safety hazards and space requirements associated with frame rotation while maintaining the structural integrity of the remaining frame during maintenance operations.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of repair

If pins of the top member are disconnected and portions of the HPGR are moved or rotatably dropped to the ground to expose force generation devices, then the devices can be accessed for maintenance, but the process is time-consuming and requires auxiliary tools

Engineering Contradiction:

Improveaccessibility of force generation deviceVSAvoiddowntime for maintenance

Core Design Contradiction:

Ease of repairVSLoss of time

Solution Approach 1:

The frame assembly is divided into separable components: top members, side members, and bottom members that can be selectively disconnected. This segmentation allows the top members to be removed independently, providing access to the force generation devices without requiring rotation or disassembly of the entire frame structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection devices (hinges or sliding mechanisms) are pre-installed on the force generation devices and frame structure, enabling quick detachment of top members without requiring auxiliary tools or complex disassembly procedures. This preliminary preparation significantly reduces maintenance downtime.

AI summary

A roller press includes a frame assembly and a force generation device. The force generation device is configured to move so that it is removable when top members of the frame assembly are connected to the side members of the frame assembly and fixed in a closed horizontal position. The connection device for attaching the force generation device to the frame assembly includes a mounting plate and a hinge or sliding device.
