Clamping Device for Filtration Cartridge Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cassette clamping devices for crossflow filter cassettes either restrict flow to be only serial or parallel, require special formats for filter cassettes, and inefficiently use pump capacity, limiting flexibility and increasing costs when dealing with large-surface filtration.
Innovation Solution
The cassette clamping device allows for orthogonal displacement of clamping plates via guide rods, enabling parallel connection of filter cassette arrangements via a common distributor plate, allowing for both series and parallel flow configurations without altering the geometry of standard filter cassettes, thus optimizing pump capacity and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If filter cassettes are arranged in parallel connection via stacked distributor plates, then flow distribution is improved and pump capacity is optimized, but the device complexity increases due to orthogonal displacement mechanisms and guide rods
Solution Approach 1:
The system is divided into multiple independent cassette filtration modules, each with its own distributor plate and clamping mechanism. These modules can be stacked and connected in parallel or series configurations, allowing flexible flow distribution without requiring a single complex integrated system.
Solution Approach 2:
The clamping plates are designed to be displaceable orthogonally to the contact surface via guide rods, enabling dynamic adjustment of the clamping force and configuration. This allows the system to adapt between parallel and series connections while maintaining proper sealing and contact between distributor plates and filter cassettes.
2Ease of manufacture
If standard filter cassettes are used without special formats, then manufacturing costs are reduced and availability is improved, but the filtration area is limited compared to custom large-surface cassettes
Solution Approach 1:
Multiple standard filter cassettes are combined through stacked distributor plates to create a large-area filtration system. The parallel connection of multiple cassettes via common distributor plates effectively merges their filtration areas, achieving the equivalent of a single large-surface cassette using readily available standard components.
Solution Approach 2:
The distributor plate design serves multiple functions: it acts as a clamping surface for filter cassettes, provides fluid distribution channels, and enables both parallel and series connections. This multi-functionality allows standard cassettes to be configured for large-area filtration without requiring custom-designed components.
3Use of energy by moving object
If pump capacity is optimized through parallel connections, then energy efficiency is improved and operating costs are reduced, but the system requires more complex valve and piping arrangements
Solution Approach 1:
The system transitions from horizontal parallel arrangements to vertical stacking of distributor plates, utilizing the vertical dimension to achieve parallel connections. This allows multiple filter cassettes to be connected in parallel through stacked distributor plates, simplifying the piping arrangement compared to traditional horizontal configurations while maintaining pump capacity efficiency.
