Dual-Fin Refractory Anchor 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 with two anchor fins having 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 merges multiple anchor functions into a single refractory anchor unit by incorporating two Y-shaped anchor fins that can form hexagonal shapes when combined with adjacent anchors. This allows the formation of stable hexagonal patterns using fewer anchors, thereby reducing installation time while maintaining the required anchoring strength.
Solution Approach 2:
The anchor fin is segmented into two Y-shaped sections with multiple branches, where each branch can independently interact with the lining material. This segmentation allows the single anchor to provide multiple anchoring points, effectively replacing the need for multiple simpler anchors and reducing overall installation time.
2Strength
If anchor fins are made taller to improve anchoring results, then anchoring strength is improved, but heat insulation performance deteriorates
Solution Approach 1:
The patent applies local quality by creating a space between the first and second anchor fin sections, which is then filled with heat-insulating lining material. This local modification provides thermal insulation at the critical heat path while maintaining the tall anchor fin structure for strong anchoring. The lining material in this space acts as a thermal barrier without compromising the anchoring strength provided by the extended fin structure.
3Temperature
If direct heat paths are reduced to protect equipment, then temperature resistance is improved, but anchoring effectiveness may deteriorate
Solution Approach 1:
The anchor fin is divided into multiple sections with a gap between the first and second anchor fin sections. This segmentation creates a discontinuous structure that interrupts direct heat paths from the hot lining material to the mounting pin, while the multiple branches of the Y-shaped sections maintain effective anchoring surface area and mechanical interlocking with the lining.
Solution Approach 2:
The heat-insulating lining material filled in the space between anchor fin sections acts as an intermediary thermal barrier. It physically separates the hot lining material from the mounting pin, blocking direct heat conduction while the anchor fin structure maintains its anchoring function through mechanical interlocking with the lining material on both sides of the insulating space.
