Solution Overview

Problem

Existing separation technologies face challenges in maintaining the purity of filtered matter and ensuring a clean filter area for continuous separation processes, leading to inefficiencies and contamination risks.

Innovation Solution

The apparatus extends filtrate chambers outside the enclosure, with one chamber always placed under the filter for collection, and includes multiple filtration layers and cleaning mechanisms to maintain purity and facilitate the removal of filter cake through rotational speed control and flushing processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the filtrate chamber is extended by more filtrate chambers separated by walls, then the purity of the filtrate is maintained and contamination is reduced, but the device complexity increases

Engineering Contradiction:

Improvepurity of filtrateVSAvoidstructure of filtrate chambers

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The filtrate chamber is divided into multiple separate chambers (first filtrate chamber and second filtrate chamber) separated by a wall. This segmentation allows independent collection and handling of filtrate in different chambers, preventing cross-contamination and maintaining purity while managing complexity through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The filtrate chamber configuration extracts the purification function from a single chamber and distributes it across multiple chambers. By separating the filtrate collection into distinct chambers with walls between them, the system ensures that purified matter remains isolated and pure, addressing the contamination risk in continuous separation processes

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If one filtrate chamber is always placed under the filter for collection, then continuous separation efficiency is improved, but the loss of time for chamber replacement or cleaning increases

Engineering Contradiction:

Improvecontinuous separation efficiencyVSAvoidtime for chamber maintenance

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system maintains continuous separation efficiency by having one filtrate chamber always positioned under the filter for collection. The multi-chamber design with walls allows the system to operate continuously without interruption for chamber replacement, as chambers can be independently managed and maintained while others remain in service

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The apparatus is configured with multiple filtrate chambers so that while one chamber is under the filter collecting filtrate, other chambers can be prepared, cleaned, or maintained outside the enclosure. This preliminary preparation of chambers eliminates downtime and maintains continuous operation

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If multiple filtration layers are used to maintain purity, then the manufacturing precision of filtration increases, but the device complexity and cost increase

Engineering Contradiction:

Improvefiltration precisionVSAvoidnumber of filtration layers

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies different filtration characteristics to different areas or stages of the filtration process through multiple layers. Each filtration layer can be optimized for specific particle sizes or types, providing locally appropriate filtration precision while maintaining overall system effectiveness through the multi-chamber configuration that prevents cross-contamination

Inventive Principle:

Principle #3Local quality

AI summary

The invention relates to an apparatus for continuous separation of dry matter from a fluid, comprising an enclosed environment capable of being under vacuum or under positive pressure, in which enclosed environment a number of rollers (1, 3, 4, 4′, 6, 6′, 20, 21, 22, 23) form a chamber which is divided into two or more compartments (12, 13, 24, 27, 25, 26) by filtration means (7, 8, 16, 29, 36, 37, 38, 40), wherein one or more filtrated chambers (9, 10) are placed on the pure side of the filter means. In order to allow for cleaning and/or maintenance of the filtrate chambers, additional filtrate chambers are provided, which are separated from the first filtrate chambers by a wall. One of the filtrate chambers at any time is placed under the filter, while the other filtrate chambers are situated outside the enclosure for maintenance/cleaning.
