AI Technical Summary

Technical Problem

In existing silicon oxide production equipment, the sealing method between the crucible and the flow guide cannot meet the sealing needs in high temperature and corrosive environments, resulting in serious reaction leakage, affecting the safety and efficiency of the equipment.

Method used

A flow tube installation structure is designed, including a leveling assembly and a flow tube. The leveling assembly realizes leveling of the crucible by adjusting the height of the leveling column, and ensures coaxial installation of the flow tube and the flow tube and the flow hole through the design of the guide surface, thereby improving the sealing effect.

Benefits of technology

This design improves the installation accuracy and sealing effect of the flow guide tube, reduces the risk of leakage during heating, and improves the safety and efficiency of silicon oxide production equipment.

Abstract

The present invention relates to a guide tube installation structure and silicon dioxide production equipment. The guide tube installation structure includes a furnace body, a leveling component, a crucible and a guide tube, the leveling component includes a crucible tray and a plurality of leveling columns, the bottom end of each leveling column is threadedly connected to the furnace body, the top end supports the crucible tray, and the crucible is arranged on the crucible tray; a guide hole is provided through the side of the crucible in the horizontal direction, the guide tube is inserted into the crucible through the guide hole, and the outer peripheral surface of the guide tube is transitionally matched with the inner wall of the guide hole, and the end of the guide tube inserted into the crucible has an annular guide surface, and the diameter of the guide surface gradually increases in the direction away from the crucible to be equal to the diameter of the outer peripheral surface of the guide tube; the synergistic effect of the above two structures can ensure that the outer peripheral surface of the guide tube and the inner wall of the guide hole are tightly fitted after installation, thereby reducing the difficulty of installing the guide tube while improving the sealing effect after installation, effectively avoiding the problem of experimental failure due to leakage during the heating process.
