A kind of quartz tube structure and processing method thereof

Abstract

The application relates to a quartz tube structure and a processing method thereof, including a quartz tube, a top piece, an opalescent flange, a main flange, a first exhaust pipe, a second exhaust pipe, an air intake pipe, a quartz ring, a top piece and a suspension ring. The head end of the tube is connected to the coaxial top piece, and the top piece is processed by lathe to form an outwardly convex arc shape. The tail end of the quartz tube is connected to the coaxial opalescent flange and the main flange in turn, and the axis of the quartz tube on the inner wall of the quartz tube is symmetrically distributed. There are two sets of plug joints, each set of plug joints includes two suspension rings arranged at intervals along the length of the quartz tube, the centerlines of the two suspension rings coincide and are parallel to the axis of the quartz tube; the center of the top piece is provided with an air inlet pipe extending outward A pair of first exhaust pipes and a pair of second exhaust pipes are arranged symmetrically with the axis of the quartz tube under the intake pipe; the outer middle part of the top sheet is connected to the outwardly extending quartz ring. The seal between the application and the connecting parts is good, the welding concentricity between the quartz tube and the milky white flange and the main flange is good, the quality is stable, and the phenomenon of bursting is effectively avoided.

Description

technical field [0001] The present application relates to the technical field of glass products, in particular to a quartz tube structure and a processing method thereof. Background technique [0002] Quartz glass products are widely used in high-tech due to their excellent physical and chemical properties. It has high temperature resistance, small thermal expansion coefficient, good thermal stability, high purity, corrosion resistance, and good electrical insulation performance. It occupies an important position in the photovoltaic solar energy manufacturing industry. quite an important position. [0003] However, due to the hardness and fragility of quartz glass, it is difficult to process, especially for large-volume quartz glass products, which is more difficult to process and has a low yield. Quartz tube is a quartz product used in the processing of monocrystalline silicon production line in the solar production line. Due to its large size, it requires high sealing per...

Quartz tube is a quartz product used in the processing of monocrystalline silicon production line in the solar production line. Due to its large size, it requires high sealing performance at the joint. The welding of milky white flange and transparent quartz tube also makes the processing of quartz tube difficult. low yield
