Modular Trolley Sealing Cover for Low-Height Flue Gas Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing devices for sintering machine flue gas circulation systems have complex structures, high manufacturing costs, and occupy excessive space, limiting operating space and increasing maintenance difficulties due to their bulky semicircular or arc designs.
Innovation Solution
A trolley sealing device with a cover body composed of semicircular arch frameworks and skins, where the frameworks integrate sealing and supporting functions, reducing the need for internal supports and allowing for modular disassembly, featuring communication assemblies for flue gas flow and oxygen adjustment, and a waste belt sealing assembly for high-temperature resistance and ease of replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a semicircular or arc sealing cover structure is used, then sealing effectiveness is improved, but the overall height increases and operating space is limited
Solution Approach 1:
The sealing cover is divided into a plurality of modular units that can be assembled together. Each unit has a simplified geometry rather than a full semicircular arc, allowing the overall structure to achieve sealing effectiveness through modular arrangement while reducing the overall height and improving space utilization.
2Reliability
If a semicircular or arc sealing cover structure is used, then sealing effectiveness is improved, but manufacturing cost and disassembly difficulty increase
Solution Approach 1:
The sealing cover is divided into a plurality of modular units that can be assembled together. Each unit has a simplified geometry rather than a full semicircular arc, allowing the overall structure to achieve sealing effectiveness through modular arrangement while reducing the overall height and improving space utilization.
Solution Approach 2:
The modular design allows the sealing cover to be dynamically assembled and disassembled. The units can be easily separated for maintenance and reassembled when needed, transforming a previously static and difficult-to-disassemble structure into a flexible modular system that improves ease of manufacture and maintenance.
3Reliability
If the sealing cover and support are designed separately, then sealing function is achieved, but structural complexity and cost increase
Solution Approach 1:
The sealing unit integrates both the sealing cover and support structure into a single unified component. The support frame and sealing elements are combined in one modular unit, eliminating the need for separate sealing cover and support designs. This merging reduces structural complexity while maintaining effective sealing function.
