Modular Filter Grids for Water Treatment Station Bed Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment systems with nozzle-type filter elements face frequent breakages and filter bed losses due to inadequate adjustment between concrete slabs, leading to short service life and interruptions in the filtering process.
Innovation Solution
The proposed open filtering system features a double bottom design with support legs, frames, and filtering assemblies that include a flat upper surface and a filtering grid, providing increased resistance and modular adaptability, allowing for easy transport and adjustment to various filter sizes, and utilizing clip and pressure coupling attachments for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If nozzle-type filter elements are used in concrete slabs, then homogeneous cleaning of the filter bed is achieved, but the filter elements break frequently and service life is reduced
Solution Approach 1:
The filtering system is divided into multiple modular concrete slabs that can be independently replaced. Each slab contains integrated filtering elements, creating segmented modules that maintain homogeneous cleaning while allowing localized replacement without system-wide shutdown
Solution Approach 2:
The concrete slabs are pre-adjusted and pre-positioned during installation to ensure proper alignment and spacing. This preliminary adjustment prevents misalignment issues that lead to breakages, while maintaining the homogeneous cleaning distribution pattern
2Productivity
If nozzle-type filter elements are used, then filtration is achieved, but filter bed losses occur due to lack of adjustment between concrete slabs
Solution Approach 1:
The adjustment mechanisms are integrated directly into the concrete slab structure itself, merging the filtration function with the adjustment function. This eliminates gaps between slabs that cause filter bed losses while maintaining filtration productivity
Solution Approach 2:
The concrete slabs incorporate adjustable parameters such as movable edges or height-adjustable support elements that allow precise control of spacing and alignment. This parameter adjustment prevents filter bed material from passing through gaps while maintaining optimal filtration flow
3Productivity
If traditional filtering systems are used, then water filtration is achieved, but interruptions in the filtering process occur due to breakages
Solution Approach 1:
The system is segmented into interchangeable concrete slab modules. When one slab becomes damaged, only that specific module needs to be replaced while the rest of the filtration system continues operating, maintaining productivity and reducing maintenance interruption time
Solution Approach 2:
The modular concrete slabs are designed for easy removal and replacement. Damaged slabs can be quickly discarded and replaced with pre-fabricated units, minimizing system downtime. The modular design allows for rapid recovery of full filtration capacity
