Detection method of blanking tube for quartz glass ingot melting

Abstract

The invention relates to a detection method of a blanking tube for quartz glass ingot melting, belonging to the technical field of quartz glass melting. The blanking tube is arranged in water, and through the impact of the material carrying gas, the water column generates liquid level floating, the acquired water column rising data is substituted into a formula to obtain a negative pressure value, and then the negative pressure value is compared with a standard production negative pressure value, so that the aim of detecting the blanking tube is qualified or not is achieved. The method is wide in application, and as long as the blanking tube is ventilated, the blanking tube can be detected by this method; and moreover, the detection result is quantified and visual; and on the premise of quantizable detection result, different solutions can be provided for actual production needs.

Description

technical field [0001] The invention relates to a detection method for a feeding pipe used for producing quartz glass ingots, and belongs to the technical field of quartz glass melting. Background technique [0002] During the melting process of quartz glass, the quartz powder is input from the feeding device and accelerated into the burner through the feeding tube with carrier gas. The feeding tube is a quartz glass tube with a vent (pipe) in the middle. Driven by the carrier gas in the vent, the quartz powder will accelerate into the burner. At the same time, on the side of the feeding port of the feeding tube, Negative pressure will be created. If the gravity of the quartz powder itself plus the momentum generated by the venting of the feeding tube exceeds the upward thermal pressure generated by the high temperature inside the furnace on the burner, the quartz powder can pass through the feeding tube smoothly, and then melted and formed by the high-temperature flame of ...

AI Technical Summary

Problems solved by technology

[0003] In the current work, there are often two extreme situations in the unloading pipe. One is that the acceleration is lower than that required for production, which causes material blockage and production cannot continue

The other is that the acceleration is higher than that required for production, causing the quartz powder inside the silo to be absorbed into the feeding pipe, resulting in uncontrolled feeding, and the accelerated quartz powder will have an excessive impact on the feeding pipe , causing its premature wear, etc.
