Pallet Container Fire Protection Insulating Mat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pallet containers for storing and transporting flammable liquids lack adequate flame protection, as components like the screw cap and removal fitting remain exposed, leading to inadequate protection against external fires, and their complex designs result in high production costs and short fire resistance durations.
Innovation Solution
A pallet container design featuring a fire protection insulating mat that encloses the plastic inner container on all sides, including the screw cap area, with overlapping cover flaps to protect these components, and an electrically conductive textile fabric layer for charge dissipation, ensuring complete coverage and enhanced thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a thin-walled thermal insulation consisting of cardboard and aluminum foil is arranged between the plastic inner container and the wire mesh cage, then the insulating layers provide some heat transfer imp ediment, but the screw cap and filling nozzle remain completely exposed and unprotected to flames
Solution Approach 1:
The fire-resistant insulating mat is divided into multiple sections (front wall section, rear wall section, two side wall sections, and base section) that can be separately assembled to completely enclose the plastic inner container, ensuring all components including the screw cap are protected
Solution Approach 2:
The fire-resistant insulating mat combines glass fiber fleece (fire resistance) with polyethylene outer layers (weather resistance), creating a composite material that provides both flame protection and durability while completely enclosing the container
2Object-affected harmful factors
If sheet metal panels are arranged between the inner container and the wire mesh frame with additional fire insulation, then fire protection is improved, but the design becomes complex and costly with multiple components
Solution Approach 1:
The fire-resistant insulating mat integrates multiple functions into a single component: fire insulation (glass fiber fleece), weather protection (polyethylene outer layers), and electrical charge dissipation (conductive coating), eliminating the need for separate sheet metal panels and simplifying the overall design
Solution Approach 2:
The fire-resistant insulating mat serves multiple purposes simultaneously: thermal insulation, flame barrier, weather resistance, electrical charge dissipation, and structural support within the wire mesh cage, reducing the total number of components needed
3Reliability
If the plastic inner container is enclosed by a grid-like covering made of thin metal wire for electrical charge dissipation, then electrical charges are dissipated, but the weight and complexity of the container increase
Solution Approach 1:
Instead of using a complete grid-like metal wire covering, the conductive coating is applied only to the inner surface of the fire-resistant insulating mat that contacts the plastic container, providing electrical charge dissipation locally where needed without adding unnecessary weight
Solution Approach 2:
The mechanical grid-like metal wire structure is replaced with a conductive coating applied to the insulating mat, achieving the same electrical charge dissipation function with significantly reduced weight and complexity
