Description

TECHNICAL FIELD

[0001] The utility model relates to quartz tube processing technical field, concretely relates to a quartz tube polishing device. BACKGROUND

[0002] Quartz tube is a tubular product with quartz material as the main component, and quartz is a high-purity silicon dioxide crystal with excellent physical and chemical properties, especially in high temperature and strong acid and alkali environment. Therefore, quartz tube is often used in various industrial applications under harsh conditions such as high temperature, high pressure, strong acid and alkali, and quartz tube is usually made of quartz blank through high-temperature melting and stretching forming. Quartz tube fire polishing is a common quartz tube surface treatment method, mainly used to improve the surface quality and precision of quartz tube, and its basic principle is to remove the small protrusions and defects on the surface of quartz tube through high-temperature melting and chemical reaction, so that the surface becomes smooth, flat and defect-free.

[0003] The traditional method is to clamp the quartz tube on the clamp and then polish it with flame, but in the polishing process, the quartz tube will be deformed and expanded by heat, so that the diameter of the quartz tube becomes larger, and generally the clamp is tightly clamped on the quartz tube to ensure the stability of clamping, and there is no any allowance left, so that the quartz tube will be squeezed after heating and expansion, so that the surface of the quartz tube is damaged or broken. In addition, for the polishing of large-diameter quartz tube, simply heating and polishing the outer surface of the quartz tube has poor effect, because the diameter of the quartz tube is large, the wall thickness is high, the flame temperature is low when heated from the outside, and the melting temperature cannot be reached, so that the hot working cannot be carried out, and if the temperature is too high, the quartz tube may be burned through during heating, which needs to be repaired later, increasing the cost.
