Refractory Anchor Fin Structure for Faster Hexagonal Lining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refractory anchors require multiple installations to form hexagonal shapes, which increases installation time and may not provide adequate protection against high temperatures and abrasive environments in vessels and cyclones.
Innovation Solution
A refractory anchor design featuring two anchor fins with V-shaped branches of equal height, allowing for the formation of hexagonal shapes using fewer anchors, and incorporating a space between fin portions filled with heat-insulating liner to reduce direct heat paths and enhance durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple refractory anchors are installed to form hexagonal shapes, then anchoring strength is improved, but installation time increases
Solution Approach 1:
The patent combines multiple anchoring functions into a single refractory anchor unit. The anchor fin structure integrates multiple attachment points and geometric configurations that previously required separate anchors, allowing one unit to provide the anchoring strength of multiple traditional anchors while reducing installation time
Solution Approach 2:
The anchor fin is divided into multiple sections (first anchor fin section and second anchor fin section) that can be independently configured. This segmentation allows the single anchor to create multiple attachment points and form hexagonal shapes with fewer units, maintaining strength while reducing the number of installations required
2Ease of manufacture
If traditional anchor designs are used, then installation is simple, but protection against high temperatures and abrasive environments is inadequate
Solution Approach 1:
The refractory anchor utilizes composite construction combining the mounting pin and anchor fin sections, which can be made from different materials optimized for specific functions. The mounting pin can be designed for easy installation while the anchor fin sections provide enhanced thermal and abrasion resistance for reliable protection in harsh environments
Solution Approach 2:
Different parts of the anchor are designed with different properties: the mounting pin section is optimized for installation simplicity while the anchor fin sections are designed with enhanced durability for high-temperature and abrasive resistance, allowing each component to excel at its specific function
3Strength
If anchor fins are made taller to improve anchoring, then anchoring strength is improved, but heat transfer to the mounting pin increases
Solution Approach 1:
The anchor fin is segmented into first and second sections with different heights. The first anchor fin section has a greater height than the second anchor fin section, creating a stepped configuration that provides sufficient anchoring strength in the lower region while reducing the height exposed to high temperatures, thereby limiting heat transfer to the mounting pin
