Description

Technical Field

[0001] This utility model relates to the field of quartz rod manufacturing technology, and in particular to a gas-refining quartz rod manufacturing apparatus. Background Technology

[0002] Quartz rods are important optical and semiconductor materials, and their fabrication process directly affects product quality and production costs. With the rapid development of the optoelectronic industry, the market demand for high-performance quartz rods continues to grow, and traditional fabrication processes can no longer meet the needs of modern production. Quartz rods are mainly used in high-end fields such as optical fiber preforms and semiconductor equipment, where strict requirements are placed on dimensional accuracy and material purity, necessitating the development of more advanced fabrication technologies.

[0003] Existing technologies mainly employ two preparation methods: one is the continuous melting method, which uses an electrically heated tungsten crucible to melt quartz sand and then produces quartz rods through a continuous drawing process; the other is a two-step gas refining method, which first uses an oxyhydrogen flame to melt quartz sand to produce long quartz rods, and then obtains the required dimensions through machining. Both methods use fixed production equipment and rely on manual control of production parameters to shape the quartz rods, which has significant technical limitations.

[0004] The main problems currently facing quartz rod production technology are: the continuous melting method for producing quartz rods cannot flexibly switch sizes, resulting in high production costs; while the two-step gas refining method suffers from significant material waste and large dimensional errors. These problems lead to unstable product quality and low production efficiency, severely restricting technological progress and industrial development in quartz rod production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gas-refined quartz rod manufacturing device, which aims to improve the existing quartz rod production technology. The continuous melting method for producing quartz rods cannot flexibly switch the size and has high production costs, while the two-step gas refining method has serious material waste and large dimensional errors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a manufacturing apparatus for gas-fired quartz rods, comprising: a feeding device, a burner, a crucible, a furnace, a support, a shaping fixture, a driving device, a cutting device, and quartz rods, wherein,

[0013] The drive device is installed at the lower end of the shaping fixture, providing power for the automatic movement of the shaping fixture on the support.

[0014] The cutting device is mounted on a bracket and can move up and down on the bracket to cut the quartz rod;

[0015] The quartz rod exits from the lower end of the crucible and is shaped by a shaping fixture.

[0016] Furthermore, the feeding device is an automatic feeding device that can monitor the feeding amount of quartz powder in real time.

[0017] Furthermore, the ratio of hydrogen to oxygen introduced into the burner is 1:2.

[0018] Furthermore, the bracket has a slide rail structure, which can ensure that the shaping tooling can move on the bracket.

[0019] Furthermore, the shaping fixture is made of graphite material and is used to shape the quartz rod. Before production, a suitable shaping fixture is selected according to the required size of the quartz rod.

[0020] Furthermore, the cutting device can be moved on the support, and before production, the cutting device can be fixed in a suitable position according to the length of the quartz rod to be produced.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 This utility model provides an embodiment of a gas-fired quartz rod manufacturing apparatus, comprising: a feeding device 1, a burner 2, a crucible 3, a furnace 4, a support 5, a shaping fixture 6, a driving device 7, a cutting device 8, and a quartz rod 9, wherein...

[0028] The feeding device 1 is connected to the burner 2 via a hose to improve the high-purity quartz powder. The high-purity quartz powder is accurately delivered to the burner 2 via the hose. The left side of the feeding device 1 is a hydrogen pipe, and the right side is an oxygen pipe.

[0029] One end of the burner 2 is connected to hydrogen, oxygen and the feeding device 1, and the other end is installed at the center of the upper end of the crucible 3. Hydrogen and oxygen are introduced in a 1:2 ratio to generate a high-temperature flame to melt the quartz powder.

[0030] The crucible 3 is fixed directly above the furnace 4 and directly below the burner 2, receiving and containing molten quartz material, and has an outlet at the lower end;

[0031] The furnace 4 is wrapped with insulating cotton to maintain the molten state of the quartz material inside the crucible 3;

[0032] The bracket 5 is fixed to the ground, providing support and a slide rail structure, so that the shaping fixture 6 can move smoothly;

[0033] The shaping fixture 6 is installed on the bracket 5 and is used to shape the quartz rod 9. It is made of graphite material and cools the molten quartz into a quartz rod 9 of a specified size.

[0034] The drive unit 7 is installed at the lower end of the shaping fixture 6, providing power for the shaping fixture 6 to move automatically on the bracket 5;

[0035] The cutting device 8 is mounted on the bracket 5 and can move up and down on the bracket 5 to cut the quartz rod 9;

[0036] Quartz rod 9 exits from the lower end of crucible 3 and is shaped by shaping fixture 6. The feeding device 1 is an automatic feeding device that can monitor the feeding amount of quartz powder in real time. The ratio of hydrogen to oxygen introduced into burner 2 is 1:2. The support 5 has a sliding rail structure to ensure that the shaping fixture 6 can move on the support 5. The shaping fixture 6 is made of graphite material and is used to shape the size of quartz rod 9. Before production, a suitable shaping fixture 6 is selected according to the size of the quartz rod 9 to be produced. The cutting device 8 can move on the support 5. Before production, the cutting device 8 is fixed in a suitable position according to the length of the quartz rod 9 to be produced.

[0037] Specifically, high-purity quartz powder is conveyed to burner 2 via a hose through an automatic feeding device 1. Simultaneously, hydrogen and oxygen are introduced into burner 2 at a fixed ratio of 1:2. The hydrogen-oxygen mixture is fully combusted in burner 2 to generate a high-temperature flame, completely melting the quartz powder. The molten quartz is dripped into crucible 3 located directly below burner 2. Furnace 4, wrapped with insulating cotton, is installed around crucible 3 to effectively maintain the molten state of the quartz. The molten quartz flows out stably from the lower outlet of crucible 3 and enters a graphite shaping fixture 6. Drive device 7 drives the shaping fixture 6 to move smoothly along the slide rail of support 5, allowing the quartz to cool evenly and gradually form into quartz rods 9 of specified dimensions during the movement. When the forming length of quartz rod 9 reaches the preset value, cutting device 8, which can be adjusted along support 5, is automatically activated to precisely cut quartz rod 9. The entire process realizes a continuous automated production process from raw material melting and forming to cutting.

[0038] Working principle: When this manufacturing device is needed, high-purity quartz powder is conveyed to burner 2 via a hose through an automatic feeding device 1. At the same time, hydrogen and oxygen are introduced into burner 2 in a 1:2 ratio. The high-temperature flame generated by combustion melts the quartz powder. The molten quartz drips into crucible 3 and remains molten in the furnace 4 wrapped with insulation cotton before flowing out from the bottom of crucible 3. The flowing molten quartz enters the graphite shaping fixture 6. The driving device 7 drives the shaping fixture 6 to move along the slide rail of the support 5, so that the quartz material cools and is shaped into quartz rods 9 of a specified size during the movement. When the shaped length reaches the set value, the adjustable cutting device 8 cuts the quartz rod 9, thus realizing the continuous automated production of quartz rods 9 from raw material melting and shaping to cutting.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
