Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refractory anchors require multiple installations to achieve strong anchoring, especially for large surfaces, and are not optimized for high-temperature and abrasive environments, leading to increased installation time and potential liner damage from thermal expansion and vibrations.
Innovation Solution
A refractory anchor design featuring an elongated mounting pin with two anchor fins forming Y-shapes, allowing for reduced anchor installation by mimicking hexagonal shapes with fewer anchors, and incorporating a height difference between anchor fin arms to reduce heat transfer and enhance vibration resistance, along with a connector for fast assembly and improved anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional refractory anchors with three anchor fins are used to achieve strong anchoring, then anchoring strength is improved, but the number of anchors required increases leading to longer installation time
Solution Approach 1:
The anchor fin is segmented into multiple sections (first anchor fin section and second anchor fin section) arranged in a Y-shape configuration. This segmentation allows two anchors to form a hexagonal pattern together, reducing the total number of anchors needed while maintaining anchoring strength through the distributed fin sections.
Solution Approach 2:
Two refractory anchors are merged to form a complete hexagonal shape, with each anchor contributing Y-shaped fin sections. This combining approach allows the anchors to work together as a unified anchoring system, reducing installation time while achieving the required anchoring strength through the hexagonal configuration.
2Area of stationary object
If multiple refractory anchors are installed on large surfaces to ensure adequate anchoring, then anchoring coverage is improved, but installation complexity and time increase
Solution Approach 1:
The anchor design segments the fin structure into multiple sections that can be arranged in hexagonal patterns across large surfaces. This segmentation allows for systematic placement of fewer anchors while ensuring adequate coverage, reducing installation complexity compared to conventional approaches requiring more anchors.
Solution Approach 2:
The Y-shaped anchor fin design serves multiple functions: it provides anchoring strength, forms hexagonal patterns when two anchors are used, and enables systematic placement on large surfaces. This multi-functionality reduces the number of different components needed and simplifies the installation process across various surface areas.
3Strength
If anchor fins are positioned close to the mounting pin for structural integrity, then structural strength is improved, but heat transfer to the mounting pin increases reducing thermal resistance
Solution Approach 1:
The anchor fin sections are positioned at different distances from the mounting pin, creating local variations in thermal resistance. The first anchor fin section is positioned closer to the mounting pin for structural strength, while the second anchor fin section extends farther away to provide a thermal barrier, optimizing both structural integrity and thermal performance locally.
Solution Approach 2:
The Y-shaped configuration extends the anchor fin in multiple directions and dimensions from the mounting pin. This dimensional arrangement creates varied thermal paths and increases the distance between the hot lining and the mounting pin in certain directions, reducing heat transfer while maintaining structural strength through the distributed fin sections.
