Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamellar modules for inclined clarifiers are heavy, complex to transport, and create dead zones in settling tanks, necessitating frequent cleaning and are not easily adaptable to varying installation sizes and conditions.
Innovation Solution
A lamellar module designed as a plug-in system with detachable connections between end, longitudinal, and lamella plates, allowing prefabrication and easy assembly at the installation site using identical parts, with adjustable geometry for various settling tank sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If lamellar modules are prefabricated as welded structures, then manufacturing is simplified, but the modules become heavy and complex to transport
Solution Approach 1:
The lamellar module is divided into separate components (end plates, longitudinal plates, lamella plates) that can be manufactured independently and assembled later using detachable plug connections, reducing the weight of each individual component that needs to be transported
2Ease of manufacture
If lamellar modules are prefabricated as welded structures, then manufacturing is simplified, but transport to installation site becomes complex
Solution Approach 1:
By segmenting the module into smaller detachable components, each piece can be transported more easily to the installation site and then assembled on-site using the detachable plug connections
Solution Approach 2:
The detachable plug connections allow the module to be dynamically assembled and disassembled, providing flexibility for transport and installation while maintaining structural integrity during operation
3Ease of operation
If support beams are used to suspend lamellar modules, then modules can be installed, but dead zones are created that require periodic cleaning
Solution Approach 1:
The module can be segmented and arranged to fill spaces more efficiently around support beams, eliminating dead zones while maintaining the suspension installation method
Solution Approach 2:
The geometry of the lamellar plates can be adjusted (e.g., varying lengths, angles, or spacing) to optimize the filling of available space and eliminate stagnant areas where dead zones would form
4Ease of manufacture
If fixed geometry lamellar modules are used, then manufacturing is simplified, but adaptation to varying tank sizes is difficult
Solution Approach 1:
The module is segmented into standardized components that can be combined in different configurations to adapt to various tank sizes and geometries while maintaining simple manufacturing of each individual component
Solution Approach 2:
The detachable plug connections create a universal system where the same standardized components can be used across different applications and tank sizes, providing versatility without complicating the manufacturing of individual parts
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates flexible installation, reduces transport complexity, eliminates dead zones, and enables efficient assembly without tools, enhancing the adaptability and efficiency of sedimentation processes.
Implementation Method 1
The end plates of each longitudinal plate have an arrangement of slots into which corresponding protruding hooks of the longitudinal plates can be detachably inserted
Implementation Method 2
each longitudinal plate has a plurality of slots extending obliquely to the horizontal... such that the longitudinal plates and the lamella plates can be detachably inserted into one another at right angles
Implementation Method 3
When installed, the lamella plates are arranged at an angle to the horizontal to allow the settled sludge to slide to the bottom of the tank
Implementation Method 4
They often consist of parallel lamella plates through which the water flows. The effect is that the sediments from the water only have to settle the small distance of a few centimeters between the lamella plates
