Description

Technical Field

[0001] This utility model relates to the field of quartz tube processing technology, specifically to an annealing device for large-size quartz tubes. Background Technology

[0002] After high-temperature molding or machining, quartz retains uneven thermal or mechanical stresses, leading to increased brittleness, susceptibility to cracking, or optical property distortions such as birefringence. Annealing relaxes these stresses through slow cooling. At high temperatures, the amorphous network structure of quartz may be locally disordered; annealing promotes atomic rearrangement, reduces structural defects, and improves density and chemical stability. Annealing reduces internal scattering centers, such as microbubbles and microcracks, improving light transmittance, especially in the ultraviolet-visible range, and reducing refractive index inhomogeneity. Therefore, annealing in an annealing furnace is an essential step for quartz materials.

[0003] Currently, there are annealing devices for small-diameter quartz tubes, but due to the different specifications of quartz tubes, the process requirements for annealing also vary. Annealing devices for small-diameter quartz tubes cannot meet the requirements. Existing large-size quartz tube annealing furnaces can usually only hold a small number of quartz tubes per furnace, or the annealing furnace needs to be structurally modified to increase its volume in order to increase the number of tubes, which results in higher annealing costs. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a large-size quartz tube annealing device, aiming to solve the problems existing in the background art.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] An annealing apparatus for large-size quartz tubes includes a material platform, a weighing plate, and two sets of limiting components. The two sets of limiting components are disposed on both sides of the material platform and are detachably connected to the material platform. A stop block is provided on the outer side of each limiting component. The stop block is fixedly connected to the limiting component. The weighing plate is located above the limiting components, and its two ends are supported by the sides of the two sets of limiting components that are close to each other. Partitions are provided at both ends of the weighing plate. The partitions are fixedly connected to the weighing plate.

[0007] Furthermore, the limiting component includes a base plate; side plates are respectively provided on both sides of the base plate; the side plates are fixedly connected to the base plate; a plurality of ribs are provided on the inner side of the base plate; the ribs are arranged in an inclined shape, with one end fixedly connected to the base plate and the other end fixedly connected to the side plate.

[0008] Furthermore, the thickness of the base plate, the side plate, and the rib plate is not less than 15mm.

[0009] Furthermore, the side plate extends outward with a protrusion; the protrusion is located at the bottom end of the side plate and is integral with the side plate.

[0010] Furthermore, the extension length of the protrusion is not less than 15mm.

[0011] Furthermore, the distance between the two sets of limiting components is not greater than the diameter of the large-size quartz tube.

[0012] The beneficial effects of the technical solution described in this utility model are as follows:

[0013] This invention forms a double-layer bearing platform by setting limiting components on both sides of the material platform and setting a weighing plate on the limiting components. The two sets of limiting components isolate multiple quartz tubes in the first layer, and the partition plate isolates multiple quartz tubes in the second layer. At the same time, the stop blocks prevent the quartz tubes from falling. Thus, it can achieve the bearing function of multiple large-size quartz tubes with a very simple structure, avoid interference between multiple quartz tubes, reduce production costs and improve production efficiency.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but it is not limited thereto. Any modifications or equivalent substitutions to the technical solution of this utility model that do not depart from the spirit and scope of the technical solution of this utility model shall be covered within the protection scope of this utility model.

[0020] like Figure 1-3As shown, this utility model proposes an annealing device for large-diameter quartz tubes, including a material platform 9, which is placed horizontally on a kiln car. Two sets of limiting components 7 are installed on the material platform 9, located on opposite sides of the platform with a gap in between, the gap being no smaller than the size of the limiting components 7. Both sets of limiting components 7 are horizontally placed on the material platform 9 and fixed solely by their own weight. A stop block 2, made of ceramic fiber blanket, is provided on the top surface of each set of limiting components 7 near the outer end face. This stop block 2 is fixedly connected to the limiting components 7 to prevent the large-diameter quartz tube from falling. A weighing plate 6 is also provided on each set of limiting components 7. One end of the weighing plate 6 is supported by the left limiting component 7, and the other end by the right limiting component 7. The weighing plate 6 is horizontally placed on the two sets of limiting components 7 and fixed by its own weight and the weight of the large-diameter quartz tube. A partition 5 is provided on both sides of the bearing plate. The partition 5 is fixedly connected to the weighing plate 6 to isolate multiple large-sized quartz tubes and prevent the quartz tubes from sticking together.

[0021] Specifically, the limiting component 7 is composed of a base plate 73 and two side plates 71, forming an open structure. The two side plates 71 are fixedly connected to the base plate 73, and the thickness of both side plates 71 and the base plate 73 is not less than 15mm. A protrusion 74 extends outward from the open end of each side plate 71, and the protrusion 74 is integrally formed with the side plate 71. The extension length of the protrusion 74 is not less than 15mm, which is used to enhance the load-bearing capacity of the limiting component 7 to ensure that the load-bearing weight of the base plate 73 is not less than 200kg. A rib 72 is provided at the connection between each side plate 71 and the base plate 73. The rib 72 is inclined, with one end fixedly connected to the side plate 71 and the other end fixedly connected to the base plate 73, which is used to enhance the structural strength of the limiting component 7.

[0022] In use, first place the quartz tube on the left side of the material platform 9 and attach the limiting component 7 with the opening facing downwards to the quartz tube. Then place the second quartz tube on the right side of the material platform 9 and attach the limiting component 7 with the opening facing downwards to the second quartz tube. Next, place the third quartz tube in the middle of the two sets of limiting components 7 and place the weighing plate 6 above the third quartz tube. Then place the fourth quartz tube on the weighing plate 6 and place the fifth and sixth quartz tubes on both sides of the weighing plate 6, separated by the partition 5. Finally, cover the weighing plate with a bell-shaped annealing hood to perform the annealing operation.

[0023] This invention forms a double-layer bearing platform by setting limiting components on both sides of the material platform and setting a weighing plate on the limiting components. The two sets of limiting components isolate multiple quartz tubes in the first layer, and the partition plate isolates multiple quartz tubes in the second layer. At the same time, the stop blocks prevent the quartz tubes from falling. Thus, it can achieve the bearing function of multiple large-size quartz tubes with a very simple structure, avoid interference between multiple quartz tubes, reduce production costs and improve production efficiency.
