Solution Overview

Problem

Existing roller presses require complex and time-consuming maintenance processes for replacing press rollers, often necessitating the use of additional support systems like cranes to facilitate quick removal and installation, which complicates the process and increases downtime.

Innovation Solution

A roller press design featuring movable intermediate supports that pivot or shift between the frame parts, allowing for easy conversion between operating and dismantling positions, enabling both rollers to be removed and installed through a single head end without external support systems, thereby simplifying the maintenance process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If additional support systems like cranes are used to facilitate roller removal and installation, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveroller removal and installationVSAvoidsupport systems
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The press frame's own head pieces serve as support structures during roller maintenance. The head pieces are designed to bear the press frame weight during operation, and can be opened to provide support during roller removal/installation without requiring external cranes or additional support systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The head pieces perform multiple functions: they support the press frame weight during normal operation, and simultaneously serve as support structures during roller maintenance when opened. This eliminates the need for separate dedicated support systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If head pieces are opened to remove rollers, then the ease of operation is improved, but the stability of the press frame deteriorates

Engineering Contradiction:
Improveroller accessVSAvoidpress frame
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The head pieces are designed to be movable between closed (operational) and open (maintenance) positions. When opened, they dynamically transition from a closed configuration that provides structural stability to an open configuration that allows roller access while still providing support.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a roller press for crushing, compacting and/or briquetting material, comprising a press frame (1) and comprising two pressing rollers (2, 3) rotatably mounted in the press frame, wherein the press frame (1) receiving the pressing forces has a frame upper part (6) and a frame lower part (7) and also head pieces (13, 14) connecting the frame upper part and the frame lower part. This roller press is characterized in that the frame upper part (6) and the frame lower part (7) are connected to one another by way of at least one movable intermediate support (15), which is arranged between the head pieces (13, 14), supports the frame upper part (6) with respect to the frame lower part (7) when the press frame is open and can be transferred from an operating position into a roller removal position, and vice versa.
