Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing centrifuge separators lack optimization in separation and clarification efficiency, leading to inefficiencies in separating liquid phases and removing solids, particularly in applications like milk processing.
Innovation Solution
The separator is designed with a separation plate package divided into two sections, where the lower section optimally separates liquid phases and the upper section clarifies the lighter liquid phase from solids, with radial inward sealing to prevent back-mixing, allowing for customized separation gap widths and plate geometries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single separation plate package is used in generic centrifuges, then the device structure is simple, but the separation and clarification efficiency is insufficient
Solution Approach 1:
The separation plate package is divided into two distinct sections: a lower separation plate pack section (6) with separation plates (3a) having first separation gap widths, and an upper separation plate pack section (7) with separation plates (3b) having second separation gap widths. This segmentation allows each section to perform specialized functions - the lower section optimizes for separating lighter liquid phase from heavier liquid phase, while the upper section optimizes for clarifying the lighter liquid phase by removing solids, thereby resolving the contradiction between structural simplicity and separation efficiency.
2Manufacturing precision
If the separation plate package is divided into sections with different separation gap widths, then separation efficiency is improved, but the device complexity increases
Solution Approach 1:
Different sections of the separation plate package are assigned different local qualities - the lower separation plate pack section has larger separation gap widths optimized for liquid-liquid separation, while the upper separation plate pack section has smaller separation gap widths optimized for solid-liquid clarification. This local differentiation of structural properties allows each region to be optimized for its specific separation task, improving overall separation efficiency while maintaining a relatively simple overall structure through modular design.
3Reliability
If radial inward sealing is implemented in the upper separation plate pack section, then back-mixing is prevented, but the device complexity increases
Solution Approach 1:
Radial inward sealing elements are selectively extracted and installed only in the upper separation plate pack section (7) where clarification function requires prevention of back-mixing between the lighter liquid phase and solids. The lower separation plate pack section (6) operates without such sealing since liquid-liquid separation does not require preventing back-mixing. This selective application of sealing elements achieves the reliability improvement where needed while minimizing the increase in overall device complexity.
