Solution Overview

Problem

Existing mechanical thickening devices for water-containing mixtures, such as slurry and industrial effluents, face issues with high wear and maintenance due to the mixture's corrosive nature, leading to frequent component damage and downtime.

Innovation Solution

A device featuring a rotor with plate-shaped entraining elements that move along a closed orbital path, where only these elements come into contact with the mixture, reducing downtime and allowing for a larger number of elements and increased drying surface, utilizing ventilation for enhanced drying with a heated air flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conveyor belts and mechanical components are used for thickening water-containing mixtures, then mechanical thickening efficiency is improved, but component wear and damage increase significantly

Engineering Contradiction:
Improvethickening efficiencyVSAvoidcomponent durability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The rotor is segmented into multiple plate-shaped elements that can be individually replaced. Instead of a single complex mechanical structure, the system uses many simple, identical plates that process the mixture in sequence, reducing the impact of damage to any single component

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The plate-shaped elements are designed as simple, inexpensive components that can be easily replaced when worn or damaged. Their simple geometry and material requirements make them far cheaper and easier to replace than conventional conveyor belts or mechanical thickening components

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Productivity

If a larger number of plate-shaped entraining elements are provided, then drying surface area increases and processing speed improves, but device complexity increases

Engineering Contradiction:
Improvedrying speedVSAvoidnumber of components
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple plate-shaped elements are merged into a single rotating rotor assembly. The plates are arranged radially and rotate together as one unit, combining many drying surfaces into a single mechanical component that simplifies the overall device structure while maintaining large total drying area

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The drying surface is extended from a two-dimensional plane to a three-dimensional rotating structure. The plates are arranged radially around the rotation axis, creating drying surfaces at multiple radii and angles, which increases total drying area without proportionally increasing device footprint

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present invention relates to a device (1) for drying a water-containing mixture comprising at least one body (2) which can be moved along a closed orbital path and is situated in the mixture during a first part of the orbital path and is situated outside the mixture during a second part of the orbital path, said body (2) comprising a number of plate-shaped entraining elements (3) which are designed in such a manner that they entrain part of the mixture. By means of such a device, a large drying surface is created, as a result of which mixtures can dry and thus thicken much more quickly.
