Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biological contact rotors for wastewater treatment face challenges in assembly complexity, labor-intensive disassembly, and inefficient use of space, leading to increased costs and logistical difficulties during installation and maintenance, with existing designs not allowing for easy replacement or adjustment of media packs without disassembling the entire structure.
Innovation Solution
A high-capacity biological contact rotor with a novel fixation system using T-shaped structural arms and self-assembly capabilities, allowing for easier installation, modular design, and independent replacement of media packs, which reduces the number of structural arms required and enhances rigidity and strength, while optimizing media density and contact area for improved organic load removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional rotors use structural members as CPS channels assembled at the work site with separate clamping arms for each package end, then the rotor can accommodate multiple media packages, but the number of arms increases to twice the number of packages and assembly becomes complex
Solution Approach 1:
The patent merges two separate clamping arms into a single integrated arm structure that can hold multiple media packages. The arm is designed with multiple clamping positions along its length, allowing it to secure several packages simultaneously, thereby reducing the total number of arms needed in the rotor structure.
Solution Approach 2:
The structural arm is designed as a multi-functional component that serves both as a support element and as a clamping mechanism for multiple media packages. The arm can be positioned and adjusted to accommodate different package configurations, making it a universal component that reduces overall structural complexity.
2Stability of the object's composition
If conventional rotors use L angles independent from arms to form the circular ring, then the structural ring can be assembled, but the assembly process becomes more difficult and time-consuming
Solution Approach 1:
The patent combines the circular ring structure with the structural arms into an integrated design. The arms are directly attached to the ring structure at predetermined locations, eliminating the need for separate L angle components. This integration simplifies the assembly process while maintaining the stability of the circular ring structure.
3Strength
If conventional rotors directly fix media on the ring structure using steel elements and Q clamps, then the media can be securely attached, but disassembly becomes labor-intensive and requires disassembling the entire structure
Solution Approach 1:
The patent segments the media fixation system into independent, modular units that can be easily detached and replaced. Each media package is secured by its own clamping mechanism on the arm, allowing individual packages to be accessed and replaced without affecting other packages or the overall rotor structure.
Solution Approach 2:
The clamping mechanism is designed to be dynamically adjustable, allowing quick release and repositioning of media packages. The clamps can be opened and closed independently at each media package location, enabling maintenance personnel to replace media efficiently without disassembling the entire rotor structure.
4Adaptability or versatility
If conventional rotors use simple arm designs with separate clamping arms for each package, then each package can be accommodated, but the scope of installation is limited and logistics become difficult
Solution Approach 1:
The structural arm is designed as a universal component that can accommodate multiple media packages of different sizes and configurations. The arm includes adjustable clamping positions and can be configured to hold various package types, thereby expanding the installation scope and simplifying logistics for different plant requirements.
