Burner Cover Fixing Jig for Glass Particulate Deposit Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing methods for glass particulate deposits face challenges in consistently fixing burners with large individual differences and their corresponding burner covers at predetermined positions, leading to positional deviations and instability in the burner flame during the manufacturing process.
Innovation Solution
A manufacturing method that involves mounting a fixing jig on the outer periphery of the burner's outermost pipe, inserting the burner cover from the tip end of the burner, and compressing a part of the fixing jig between the burner cover and the burner to securely fix the burner cover at a predetermined position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the burner cover is fixed to the burner by a fixing material such as Teflon tape, then the burner cover can be attached to the burner, but the fixing material cannot support the burner cover and the position of the burner cover deviates during repeated manufacturing
Solution Approach 1:
A fixing jig made of heat-resistant material (such as alumina or silicon carbide) is introduced as an intermediary component between the burner cover and the burner. The fixing jig has a specific structure with a large-diameter portion and a small-diameter portion that provides mechanical support and positioning, preventing the burner cover from deviating during repeated manufacturing while maintaining ease of attachment and detachment.
2Reliability
If the burner cover is securely fixed by wrapping fixing tape material, then the burner cover is fixed to the burner, but it is not possible to detach the burner cover for replacement
Solution Approach 1:
The fixing system is segmented into separate components: the burner cover, the fixing jig, and the burner. The fixing jig acts as an independent intermediate component that can be detached. This segmentation allows the burner cover to be securely fixed during manufacturing while enabling easy detachment for replacement or cleaning by simply removing the fixing jig.
3Ease of manufacture
If the burner cover is inserted too deeply or only to the front of the burner due to shape differences, then the burner cover can be attached, but the position of the burner cover cannot be reproduced and the flame state becomes unstable
Solution Approach 1:
The fixing jig has different local structures designed for specific functions: a large-diameter portion that provides stable support and prevents deep insertion, and a small-diameter portion that ensures proper positioning. This local quality differentiation in the fixing jig's structure ensures that the burner cover is consistently positioned at the correct depth, achieving position reproducibility while maintaining ease of attachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for easy and secure attachment of the burner cover, preventing positional deviations and ensuring stability of the burner flame, even when manufacturing glass particulate deposits with varying burner shapes and sizes.
Implementation Method 1
compressing a part of the fixing jig between the burner cover and the burner to securely fix the burner cover at a predetermined position
Implementation Method 2
glass particulates formed as a result of a flame hydrolysis reaction in flame formed by the burner
Implementation Method 3
the tip end of the burner is covered with a detachable burner cover (burner hood) to prevent attachment of the glass particulates to a tip end of the burner

AI summary
Provided is a glass particulate deposit manufacturing method for manufacturing a glass particulate deposit comprising mounting a fixing jig on an outer periphery of an outermost pipe of a burner; inserting a burner cover from a tip end of the outermost pipe of the burner; and sandwiching and compressing a part of the fixing jig between the burner cover and the outermost pipe of the burner to fix the burner cover to the burner, wherein an outer diameter of a part of the fixing jig that is not compressed is greater than an inner diameter of a part of the burner cover inserted to the tip end of the outermost pipe of the burner.
