Solution Overview

Problem

Existing centrifuges with radially flowing material into a pack of separating discs face inefficiencies in material feeding, particularly with unstable and impractical designs when tubular elements are integrated into the drum base.

Innovation Solution

Arranging tubular elements on the outer circumference of the disk pack, which are fastened to the outside, allows for a stable and efficient feeding of material into the separating disk pack across its axial height, using semi-cylindrical or other non-closed channel designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If tubular elements are integrated into the drum base, then material distribution is achieved, but the design becomes unstable and impractical at high speeds

Engineering Contradiction:
Improvematerial distributionVSAvoiddesign stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The tubular elements are extracted from the drum base integration and repositioned on the outer circumference of the disk pack. This separation allows the elements to function for material distribution while being supported by the more stable disk pack structure, resolving the instability issue at high speeds.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of integrating the tubular elements into the drum base as previously done, the invention inverts the arrangement by placing them on the outer circumference of the disk pack. This inverted configuration provides both stability and functional effectiveness.

Inventive Principle:
Principle #13The other way round (Inversion)

2Productivity

If material is fed radially from the outside into the separating disk pack, then centrifugal separation is achieved, but feed efficiency is insufficient

Engineering Contradiction:
Improvefeed efficiencyVSAvoidmaterial distribution uniformity
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The tubular elements are segmented along the axial height of the disk pack, with multiple elements distributed at different axial positions. This segmentation allows material to be fed at multiple points simultaneously, improving both feed efficiency and distribution uniformity across the entire disk pack height.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention adds the axial dimension to the material feed strategy by distributing tubular elements vertically along the disk pack height. This transforms the feed approach from a single radial point to multiple radial points across the axial dimension, enhancing distribution uniformity.

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