Multi-Layer Fireproof Insulating Roll for Tank Cars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank cars lack effective fireproofing and thermal insulation solutions, particularly for transporting flammable and thermally sensitive materials, which poses risks during transportation and in case of accidents.
Innovation Solution
A multi-layer fireproof insulating roll with a fire-resistant layer and a thermally insulating layer, integrated with securing straps, is deployed over tank cars to provide comprehensive fireproofing and insulation. The roll is designed to be easily secured around the tank car's circumference, ensuring the fire-resistant layer is firmly retained and the insulating layer is in contact with the tanker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-layer insulation material is used on tank cars, then the installation process is simple, but the fire resistance and thermal insulation performance are insufficient
Solution Approach 1:
The patent applies composite materials by combining a fire-resistant layer (e.g., ceramic fiber blanket) with a thermal insulation layer (e.g., foam insulation) to create a multi-layer insulating roll. This composite structure provides both fire resistance and thermal insulation properties that a single material cannot achieve, directly resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The insulation system is segmented into distinct functional layers: a fire-resistant layer positioned against the tank car surface and a thermal insulation layer positioned against the fire-resistant layer. This segmentation allows each layer to perform its specific function optimally while maintaining overall system reliability.
2Reliability
If traditional insulation materials are applied to tank cars, then the installation process is straightforward, but the materials do not conform to the curved surface of the tank car
Solution Approach 1:
The patent employs flexible insulation materials including a fire-resistant layer made of flexible ceramic fiber blanket and a thermal insulation layer made of flexible foam. These flexible materials can conform to the curved surface of the tank car while maintaining their insulating properties, enabling reliable contact without complex installation procedures.
Solution Approach 2:
The multi-layer insulating roll is designed with flexible materials that can dynamically adapt to the tank car's surface geometry. The layers can bend and conform to curved surfaces during installation, providing reliable contact while keeping the installation process straightforward.
3Reliability
If the fire-resistant layer is positioned away from the tank car surface, then the thermal insulation layer can be in direct contact with the tank car, but the fire-resistant layer cannot provide effective protection
Solution Approach 1:
The patent segments the insulation system into two distinct layers with specific positioning: the fire-resistant layer is positioned in direct contact with the tank car surface to provide fire protection, while the thermal insulation layer is positioned against the fire-resistant layer to provide thermal insulation. This segmentation allows both functions to be performed effectively simultaneously.
Solution Approach 2:
The composite structure places the fire-resistant layer (ceramic fiber blanket) in contact with the tank car surface, followed by the thermal insulation layer (foam). This arrangement ensures the fire-resistant layer can effectively protect against external fires while the thermal insulation layer maintains temperature control, resolving the contradiction between fire protection and thermal insulation performance.
