Modular Centrifugal Separator With Exchangeable Disc Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular centrifugal separator systems face limitations in providing different separation capacities with existing technologies, as they often require specific centrifugal forces and disc configurations tailored to specific separation operations, which can be inflexible and costly for varying liquid feed mixtures.
Innovation Solution
The introduction of a modular centrifugal separator system with exchangeable separation inserts, each having different area equivalents, allowing for the same external shape to fit within a base unit, enabling selection of adequate separation capacity by swapping inserts, thus accommodating varying separation requirements without altering the base unit's configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modular centrifugal separator system uses a fixed base unit with exchangeable separation inserts, then the system provides flexibility for different separation capacities, but the device complexity increases due to multiple insert configurations
Solution Approach 1:
The centrifugal separator is divided into a base unit and exchangeable separation inserts. The separation insert is further segmented into a stack of individual separation discs within a rotor casing. This segmentation allows the user to exchange only the separation insert (specifically the stack of discs) to change separation capacity, rather than replacing the entire device. The base unit remains fixed and reusable, reducing overall system complexity while maintaining flexibility.
Solution Approach 2:
The base unit is designed as a universal platform that can accommodate multiple different separation inserts with varying capacities. The rotor casing and fluid connection interfaces are standardized to work with the base unit, allowing a single base unit to perform multiple separation functions by simply changing the separation insert. This multi-functionality approach reduces the need for multiple complete separator systems.
2Adaptability or versatility
If the separation inserts have different area equivalents for different separation capacities, then the system can adapt to varying liquid feed mixtures, but the manufacturing cost increases due to producing multiple insert variants
Solution Approach 1:
The separation insert is segmented into a stack of identical or similar individual separation discs. By varying only the number of discs in the stack (the area equivalent), different separation capacities are achieved while maintaining the same basic disc design and rotor casing. This reduces manufacturing complexity compared to designing entirely different insert configurations, as the same disc template can be reused multiple times in different quantities.
Solution Approach 2:
The separation capacity is adjusted by changing a single key parameter: the area equivalent of the separation discs, which can be modified by varying the number of discs in the stack, their diameter, or their spacing. This parameter change approach allows for scalable separation capacities while maintaining a consistent base design, simplifying manufacturing compared to redesigning entire insert structures for different capacities.
3Stability of the object's composition
If exchangeable separation inserts with same external shape are used, then the inserts fit the base unit consistently, but the design flexibility for optimizing separation capacity is limited
Solution Approach 1:
The separation discs are nested within the rotor casing in a stack configuration. The rotor casing provides a standardized external shape that fits the base unit, while the internal arrangement of nested discs can be varied to achieve different area equivalents. This nesting approach maintains external compatibility (the rotor casing dimensions remain consistent) while allowing internal flexibility in disc configuration, number, and arrangement to optimize separation capacity for different applications.

Function Achieved in This Case
This approach provides greater flexibility and cost-effectiveness by allowing different separation performances within the same base unit, adapting to specific separation needs, such as cell culture mixtures, through the use of differently sized or configured separation discs, optimizing separation efficiency and reducing costs for lower capacity operations.

AI summary
A modular centrifugal separator system is configured for separating a liquid feed mixture into a heavy phase and light phase. The system includes a base unit and a set of a first and a second exchangeable separation inserts. The base unit includes a stationary frame and a rotatable member. The rotatable member delimits an inner space configured for receiving at least one part of the first or second exchangeable separation insert therein. Each of the first and second exchangeable separation inserts includes a rotor casing forming a separation space and separation discs arranged in the separation space. The discs of the first exchangeable separation insert have a first area equivalent and the discs of the second exchangeable separation insert have a second area equivalent, which differs from the first area equivalent.
