Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel tank producing apparatuses face challenges in uniformly heating tank containers in a short period due to reliance on ambient temperature heating and local heating methods, which are inefficient and time-consuming.
Innovation Solution
A fuel tank producing apparatus with a rotating portion that reverses the direction of the tank container relative to the gas flow from a nozzle positioned off-center, combined with a heating system that includes a nozzle extending along the central axis and a mouthpiece heating portion, ensures uniform and efficient heating by maintaining contact with hot air and utilizing thermal conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If heating is performed by surrounding ambient temperature, then the heating process is simple, but it takes a long time to heat the tank container
Solution Approach 1:
A circulating hot air current is introduced as an intermediary heating medium between the heating source and the tank container. The hot air circulates around the tank container, efficiently transferring thermal energy to heat the resin layer and liner uniformly and rapidly, resolving the contradiction between simple heating process and long heating time.
2Loss of time
If local heating with a nozzle is used, then heating time is reduced, but the tank container cannot be uniformly heated
Solution Approach 1:
The tank container is rotated dynamically during the heating process, allowing the localized hot air stream to continuously sweep across different surfaces of the container. This dynamic rotation ensures that all areas receive equivalent heating exposure, achieving both rapid heating and uniform temperature distribution throughout the tank container.
3Device complexity
If the nozzle is positioned vertically relative to the central axis, then the structure is simple, but the gas does not flow efficiently along the tank perimeter
Solution Approach 1:
The nozzle is positioned asymmetrically relative to the vertical central axis of the tank container, creating an optimized airflow pattern. This asymmetric positioning allows the hot air to flow more effectively along the tank perimeter, improving heat transfer efficiency and reducing heating time without significantly complicating the overall structure.

AI summary
Provided is a fuel tank producing apparatus capable of uniformly heating a tank container in a short period of time. The fuel tank producing apparatus includes a heat curing furnace for heating the tank container and a hot air generator for generating hot air. The heat curing furnace is internally provided with a nozzle for blowing the hot air onto the surface of the tank container, and externally provided with a rotating portion for rotating the tank container about the central axis thereof. The nozzle is located at a position displaced to the left relative to the vertical direction to the central axis of the tank container as viewed from the direction of the central axis of the tank container. The rotating portion is configured to rotate the tank container in the reverse direction of a direction in which the hot air is blown from the nozzle.
