[0039] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0040] See also Figure 1 and Figure 2 As shown, this embodiment provides a quartz tube polishing device, including a hydrogen diffusion shell 100, a first oxygen diffusion shell 200, a second oxygen diffusion shell 300 and a third oxygen diffusion shell 400; the third oxygen diffusion shell 400 is sealed and sleeved on the outer wall of the second oxygen diffusion shell 300, and the second oxygen diffusion shell 300 is sealed and sleeved on the outer wall of the first oxygen diffusion shell 200, and the exhaust ports of the first oxygen diffusion shell 200, the second oxygen diffusion shell 300 and the third oxygen diffusion shell 400 are all provided with a plurality of quartz wick tubes 500, and the other end of the quartz wick tubes 500 is located at the combustion port 110 of the hydrogen diffusion shell 100.

[0041] Specifically, the quartz tube polishing device adopts an arrangement of one main hydrogen pipe and three oxygen pipes. In actual operation, for quartz tubes with larger diameters, three oxygen inlet pipes 800 corresponding to the first oxygen diffusion shell 200, the second oxygen diffusion shell 300 and the third oxygen diffusion shell 400 work simultaneously to generate a high-temperature flame with a wide coverage range, thereby improving the efficiency of the polishing operation. For quartz tubes with smaller diameters, only one or two oxygen inlet pipes 800 can be opened to form a high-temperature flame with a smaller area, thereby improving the polishing efficiency and quality. Such a design not only optimizes the polishing process, but also improves the polishing quality of the quartz tube.

[0042] The hydrogen diffusion shell 100 is connected to a hydrogen intake pipe 120 , and the first oxygen diffusion shell 200 , the second oxygen diffusion shell 300 and the third oxygen diffusion shell 400 are all connected to an oxygen intake pipe 800 .

[0043] It should be noted that the hydrogen diffusion shell 100 has a hydrogen diffusion cavity, so that the hydrogen entering the hydrogen diffusion shell 100 from the hydrogen inlet pipe 120 can diffuse in the hydrogen diffusion cavity, and the hydrogen can move along the hydrogen diffusion cavity to the combustion port 110, so that the hydrogen and oxygen are combined and burned. In addition, the first oxygen diffusion shell 200, the second oxygen diffusion shell 300 and the third oxygen diffusion shell 400 all have oxygen diffusion cavities, so that the oxygen entering the first oxygen diffusion shell 200, the second oxygen diffusion shell 300 and the third oxygen diffusion shell 400 from the respective oxygen inlet pipes 800 can be diffused and discharged from the corresponding quartz wick tube 500 to mix with the hydrogen and burn.

[0044] The oxygen intake pipe 800 includes a first oxygen intake pipe 810, a second oxygen intake pipe 820 and a third oxygen intake pipe 830; the first oxygen intake pipe 810 is connected to the first oxygen diffusion shell 200, the second oxygen intake pipe 800 is connected to the second oxygen diffusion shell 300, and the third oxygen intake pipe 830 is connected to the third oxygen diffusion shell 400.

[0047] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, a quartz wick tube reinforcement plate 700 is provided on the plurality of quartz wick tubes 500 .

[0048] Specifically, a quartz wick tube reinforcement plate 700 is provided at the cantilever end of the plurality of quartz wick tubes 500. The provision of the quartz wick tube reinforcement plate 700 can strengthen the structure of the quartz wick tube 500 to prevent a single quartz wick tube 500 from breaking and spreading to the surrounding quartz wick tubes 500. Through such a provision, even if a certain quartz wick tube 500 is damaged, it will not affect the adjacent quartz wick tubes 500, thereby effectively reducing the decrease in polishing efficiency and the increase in maintenance costs and replacement frequency.

[0049] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, a fixed support rod 900 is provided between the first oxygen inlet pipe 810 , the second oxygen inlet pipe 820 and the third oxygen inlet pipe 830 .

[0050] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, the quartz wick tube reinforcement plate 700 divides the internal cavity of the hydrogen diffusion shell 100 into a hydrogen delivery cavity 130 and a hydrogen-oxygen mixing cavity 140 .

[0051] The diameter of the hydrogen diffusion shell 100 located at the hydrogen-oxygen mixing chamber 140 gradually decreases from one end away from the combustion port 110 to the other end.

[0053] Specifically, the quartz tube polishing device provided in this embodiment adopts a unique combustion structure, and is provided with a hydrogen diffusion shell 100, a first oxygen diffusion shell 200, a second oxygen diffusion shell 300 and a third oxygen diffusion shell 400, so that one hydrogen inlet pipe 120 is matched with three oxygen inlet pipes 800, the hydrogen inlet pipe 120 is equipped with a hydrogen diffusion chamber, and each oxygen inlet pipe 800 is equipped with an oxygen diffusion chamber, ensuring that the three oxygen diffusion chambers correspond to their respective gas outlet areas, and each chamber is equipped with a corresponding number of quartz wick tubes 500, and multiple quartz wick tubes 500 are arranged in an annular equidistant manner. Among them, the first oxygen diffusion shell 200 is equipped with 7 quartz wick tubes 500, the second oxygen diffusion shell 300 is equipped with 12 quartz wick tubes 500, and the third oxygen diffusion shell 400 is equipped with 24 quartz wick tubes 500. Through such a setting, the welding gun can flexibly adjust the size and temperature of the flame according to the diameter of the quartz tube.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
