Description

Technical Field

[0001] This utility model relates to the field of quartz glass product processing technology, and in particular to a sintering support for quartz glass products. Background Technology

[0002] The production of quartz glass products involves core processes such as raw material pretreatment, forming, and sintering. First, high-purity quartz sand is pulverized to the micron level, impurities are removed, and then it is mixed with a binder. This mixture is then used to form a green body through methods such as slip casting, pressing, or injection molding. The green body undergoes a low-temperature debinding treatment to remove the binder and create a preliminary porous structure, before proceeding to the sintering stage. The sintering process takes place in a specialized kiln, where the temperature is gradually increased to 1200-1700℃, softening and melting the surface of the quartz particles. Surface tension and atomic diffusion fill the pores, ultimately forming dense, transparent quartz glass products with excellent high-temperature resistance and corrosion resistance, widely used in high-end fields such as semiconductors, optics, and photovoltaics. In the sintering process of quartz glass tubes / rods, quartz glass preforms are often stacked on supports to improve production efficiency. However, traditional supports are mostly flat plates or simple grid structures. The stacked preforms block each other, making it difficult for the hot airflow in the kiln to penetrate the gaps between the preforms evenly. This results in some preforms being under-sintered and having low density, while others are over-sintered, deformed, or crystallized, seriously affecting product consistency and yield.

[0004] Therefore, the purpose of this utility model is to provide a sintering support for quartz glass products, so as to make the sintering space layout more reasonable, ensure sintering heating, and improve the sintering effect.

[0005] To achieve the above objectives, this utility model proposes a sintering support for quartz glass products, including a base, a support column, and a suspension frame assembly. The support column is vertically disposed at the middle position of the upper surface of the base, and the suspension frame assembly is disposed on the support column. The suspension frame assembly includes a sintering tray, a main support groove, and a cross support groove. The sintering tray is sleeved on the support column, and the main support groove and the cross support groove are both disposed on the upper surface of the sintering tray.

[0006] Furthermore, the main bracket is provided in multiple groups, with the main brackets in each group being parallel to each other, the main brackets in adjacent groups being perpendicular to each other, and the intersection of the main brackets forming a cross bracket.

[0007] Furthermore, the cross-sections of the main bracket and the cross bracket are both concave arc-shaped structures, the surfaces of the main bracket and the cross bracket are provided with supporting protrusions, and the bottoms of the main bracket and the cross bracket are provided with heat-conducting holes.

[0008] Furthermore, the support column is provided with multiple parallel limiting grooves in the circumferential direction. The limiting grooves are annular structures, and the vertical spacing between adjacent limiting grooves is equal.

[0009] Furthermore, a positioning component is provided through the middle of the sintering tray. The positioning component includes a sleeve, which is sleeved on the outside of the support column. A sleeve bracket is provided at the bottom of the sleeve, and a positioning buckle is provided on the sleeve bracket. A positioning screw is horizontally provided through the positioning buckle, and the positioning screw is compatible with the limiting groove.

[0010] Furthermore, a heat equalization plate is provided at the bottom of the sintering tray.

[0011] Beneficial effects: This utility model sets multiple suspension frame components on the support column, and the multiple suspension frame components are stacked on the support column with gaps between them. This ensures that the glass tubes on each layer of sintering plate are not blocked during the sintering process and are heated evenly.

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The sintering support for quartz glass products according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, the quartz glass product sintering support provided in this embodiment of the present invention includes a base 3, a support column 2, and a suspension frame assembly 1. The support column 2 is vertically disposed at the middle position of the upper surface of the base 3, and the suspension frame assembly 1 is disposed on the support column 2. The suspension frame assembly 1 includes a sintering tray 12, a main tray 14, and a cross tray 16. The sintering tray 12 is sleeved on the support column 2, and the main tray 14 and the cross tray 16 are both disposed on the upper surface of the sintering tray 12.

[0018] Specifically, when using the quartz glass product sintering support of this application, the vertical spacing between adjacent sintering support plates 12 is first adjusted according to the sintering requirements of glass tubes / glass rods of different diameters to ensure that the glass tubes on each sintering plate are not obstructed during the sintering process and are heated evenly.

[0019] The glass tubes / glass rods to be sintered are then placed one by one into the main support 14 and the cross support 16. The main support 14 mainly supports the middle part of the glass tube, while the cross support 16 supports the two ends of the glass tube. Therefore, the cross support 16 can be reasonably arranged according to glass tubes of different lengths, saving sintering space on the plane of the sintering support plate 12 and making the sintering space layout more reasonable.

[0020] In one embodiment of this utility model, such as Figure 2 As shown, multiple sets of main brackets 14 are provided. The main brackets 14 in each set are parallel to each other, and the main brackets 14 in adjacent sets are perpendicular to each other. The intersection of the main brackets 14 forms a cross bracket 16.

[0021] Specifically, this design allows the main support 14 to support the middle part of the glass tube, and the cross support 16 to support the two ends of the glass tube. The cross support 16 can be reasonably arranged according to glass tubes of different lengths, saving sintering space on the plane of the sintering support plate 12 and making the sintering space layout more reasonable.

[0022] In one embodiment of this utility model, such as Figure 2 As shown, the cross-sections of the main bracket 14 and the cross bracket 16 are both concave arc structures. The surfaces of the main bracket 14 and the cross bracket 16 are provided with support protrusions 13, and the bottoms of the main bracket 14 and the cross bracket 16 are provided with heat conduction holes 15.

[0023] Specifically, to ensure that the bottom of the glass tube is not obstructed during the sintering process, after the glass tube is placed in the main support 14 or the cross support 16, the support protrusion 13 on the main support 14 and the cross support 16 suspends the bottom of the glass tube, leaving an airflow channel. Combined with the heat conduction holes 15 at the bottom of the main support 14 and the cross support 16, the upper surface of the main support 14 and the cross support 16 has good heat conduction function, and the hot airflow can pass through the bottom of the glass tube more easily, so that the bottom of the glass tube can also be sintered well, ensuring the sintering effect.

[0024] In one embodiment of this utility model, such as Figure 1 As shown, the support column 2 has multiple parallel limiting grooves 21 arranged in the circumferential direction. The limiting grooves 21 are annular structures, and the vertical spacing between adjacent limiting grooves 21 is equal.

[0025] A positioning component 4 is provided through the middle of the sintering tray 12. The positioning component 4 includes a sleeve 41, which is sleeved on the outside of the support column 2. A sleeve bracket 42 is provided at the bottom of the sleeve 41. A positioning buckle 43 is provided on the sleeve bracket 42. A positioning screw 44 is horizontally provided through the positioning buckle 43. The positioning screw 44 is compatible with the limiting groove 21. The sleeve 41, the sleeve bracket 42 and the positioning screw 44 are all made of high-temperature ceramic material.

[0026] Specifically, when it is necessary to adjust the vertical distance between the sintering tray 12, first loosen the positioning screw 44. After the positioning screw 44 disengages from the limiting groove 21, the sintering tray 12 and the sleeve 41 can slide up and down along the support column 2. After adjusting the vertical position of the sintering tray 12, tighten the positioning screw 44 to lock the sleeve 41, thereby locking the position of the sintering tray 12. In addition, the sintering tray 12 can also be rotated along the limiting groove 21 to adjust the rotation angle. After adjusting the angle of the sintering tray 12, tighten the positioning screw 44.

[0027] In one embodiment of this utility model, such as Figure 1 As shown, a heat equalization plate 11 is provided at the bottom of the sintering tray 12. The heat equalization plate is made of high-purity silicon nitride ceramic, which makes the surface temperature of the sintering tray 12 more uniform.

[0028] To clearly illustrate the above embodiments, refer to Figure 1 and Figure 2The specific working principle of the quartz glass product sintering support of this utility model is as follows: When using the quartz glass product sintering support of this application, firstly, the vertical distance between adjacent sintering support plates 12 is adjusted according to the sintering requirements of glass tubes / glass rods of different diameters. First, the positioning screw 44 is loosened. After the positioning screw 44 is disengaged from the limiting groove 21, the sintering support plate 12 and the sleeve 41 can slide up and down along the support column 2. After adjusting the vertical position of the sintering support plate 12, the positioning screw 44 is tightened to lock the sleeve 41, thereby locking the position of the sintering support plate 12. The sintering support plate 12 can also be rotated along the limiting groove 21 to adjust the rotation angle. After adjusting the angle of the sintering support plate 12, the positioning screw 44 is tightened to ensure that the glass tubes on each sintering plate are not obstructed during the sintering process and are heated evenly.

[0029] The glass tubes / glass rods to be sintered are then placed one by one into the main support 14 and the cross support 16. The main support 14 mainly supports the middle part of the glass tube, while the cross support 16 supports the two ends of the glass tube. Therefore, the cross support 16 can be reasonably arranged according to glass tubes of different lengths, saving sintering space on the plane of the sintering support plate 12 and making the sintering space layout more reasonable.

[0030] After the glass tube is placed in the main support 14 or the cross support 16, the support protrusion 13 on the main support 14 and the cross support 16 suspends the bottom of the glass tube, leaving an airflow channel. Together with the heat conduction holes 15 at the bottom of the main support 14 and the cross support 16, the upper surface of the main support 14 and the cross support 16 has good heat conduction function, and the hot airflow can pass through the bottom of the glass tube more easily, so that the bottom of the glass tube can also be sintered well, ensuring the sintering effect.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
