Description

Technical Field

[0001] This utility model relates to the field of quartz glass furnace technology, specifically a natural air-cooled structure for a quartz glass furnace. Background Technology

[0002] Quartz glass is made by melting various pure natural quartz (such as crystal, quartz sand, etc.) or synthetic silane. Its main component is silicon dioxide, with a content of up to 99.99%. A quartz glass furnace is a device used to heat and melt quartz raw materials to make quartz glass. It mainly consists of a furnace shell, insulation layer, refractory layer, crucible, and heater. Raw materials such as quartz sand are placed in the crucible, and the heater is started to raise the temperature to about 1700℃-2000℃, and the quartz raw materials gradually melt.

[0003] In existing technologies, furnaces dissipate a significant amount of heat during operation, causing the ambient and equipment temperatures to rise continuously. To prevent excessively high ambient temperatures, large amounts of water are used for cooling critical components. This cooling process consumes substantial energy and power, resulting in high costs for cooling water and power, thus increasing production costs. Furthermore, during material melting, operators use probes inserted into the furnace to remove material from the crucible through a sticking motion. Due to the material's weight and high viscosity, a support rod is needed to support the probe, allowing the operator to use the rod as a fulcrum to lift the material. However, in practice, the support rod height is fixed, and different operators require different heights, resulting in poor flexibility. Therefore, we propose a natural air-cooled structure for quartz glass furnaces to address these shortcomings. Utility Model Content

During the heating process, a negative pressure is formed by the pressure difference of the air inlet and outlet ducts 13 on the annular shell 7, which in turn forms natural air cooling. The heat can be dissipated without the need for power, and the temperature inside the furnace body 2 is not lost. By starting the fan 10, the air circulation inside the annular shell 7 can be accelerated, and the cooling effect can be improved.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, the adjusting assembly 6 includes a sleeve 601, a first movable rod 602, a toothed groove 603, a fixing plate 604, a connecting rod 605, a gear 606, a mounting plate 607, a cylinder 608, and a second movable rod 609. There are two sleeves 601. The bottom end of each sleeve 601 is fixedly connected to the top end of the base 1. The first movable rod 602 is slidably connected to the inside of the sleeve 601. The toothed groove 603 is formed on the outside of the first movable rod 602. The bottom end of the fixing plate 604 is fixedly connected to the top end of the base 1. The outer side of the connecting rod 605 rotates... The gear 606 is fixedly connected to the inner wall of the fixed plate 604, and the gear 606 is fixedly connected to both ends of the connecting rod 605. The gear 606 meshes with the first movable rod 602 through the tooth groove 603. The bottom end of the mounting plate 607 is fixedly connected to the top end of the base 1. The bottom end of the cylinder 608 is fixedly connected to the top end of the mounting plate 607. The second movable rod 609 is movably connected to the inside of the support rod 5. The bottom end of the second movable rod 609 is fixedly connected to the output shaft of the cylinder 608. The two ends of the bottom side of the second movable rod 609 are fixedly connected to the top end of the first movable rod 602. By activating cylinder 608, the second movable rod 609 is pushed to move up and down, so that the second movable rod 609 extends out from the inside of support rod 5. Personnel can use the second movable rod 609 to replace support rod 5, and it can be adjusted as needed to improve the flexibility of the device. When the second movable rod 609 moves, it can drive the first movable rod 602 to slide in sleeve 601, and at the same time drive gear 606 to rotate. Through gear 606, synchronization can be forced to achieve stable vertical movement.

[0020] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the assembly / disassembly component 8 includes a slot 801, a bidirectional threaded rod 802, a connecting plate 803, a movable plate 804, a plug rod 805, a knob 806, and a slider 807. The slot 801 is located inside the annular housing 7. The bidirectional threaded rod 802 is rotatably connected to the inside of the slot 801. There are two connecting plates 803, which are threaded to both ends of the bidirectional threaded rod 802. The outer side of the movable plate 804 is fixedly connected to one end of the connecting plate 803. One end of the plug rod 805 is fixedly connected to the outer side of the movable plate 804. The plug rod 805 matches the model of the slot 12. The bottom end of the knob 806 is fixedly connected to the top end of the bidirectional threaded rod 802. The knob 806 is located at the top of the annular housing 7. The slider 807 is fixedly connected to both sides of the movable plate 804. The movable plate 804 is slidably connected to the inner wall of the slot 801 through the slider 807. The fan 10 can be installed and removed more easily by disassembling and assembling component 8. By turning knob 806, the bidirectional threaded rod 802 can be rotated, which can drive the two connecting plates 803 to move closer to each other, and at the same time drive the two movable plates 804 to move closer to each other, so that the insertion rod 805 can be disengaged from the inside of slot 12, thereby releasing the restriction on disassembly and assembly plate 9. Then the fan 10 can be pulled out for maintenance and cleaning.

[0021] Working principle: During use, the material is introduced into the furnace body 2 through the material pipe 3 for heating. During the heating process, the pressure difference of the air inlet and outlet ducts 13 on the annular shell 7 forms a negative pressure, which in turn forms natural wind cooling. The heat can be dissipated without power and the temperature inside the furnace body 2 is not lost. By starting the fan 10, the air circulation inside the annular shell 7 can be accelerated to improve the cooling effect. When the fan 10 is damaged or the fan blades are covered with a lot of dust, the double-threaded rod 802 can be rotated by turning the knob 806. Since the double-threaded rod 802 has two threads with opposite directions on its surface, it can drive the two connecting plates 803 to move in different directions. When the two connecting plates 803 are close to each other, they can drive the two movable plates 804 to be close to each other, so that the insertion rod 805 is disengaged from the inside of the slot 12, thereby releasing the restriction on the disassembly plate 9. Then the disassembly plate 9 and the fan 10 can be pulled out for maintenance and cleaning of the fan 10. During material handling, a probe is inserted into the furnace body to remove the material from the crucible by adhesive means. During this process, the probe is supported by a support rod 5. The operator can use the support rod as a fulcrum to lift the material. For operators of different heights, the second movable rod 609 is moved up and down by starting the cylinder 608. The second movable rod 609 extends out from inside the support rod 5. The operator can use the second movable rod 609 instead of the support rod 5. It can be adjusted as needed to improve the flexibility of the device. When the second movable rod 609 moves, it can drive the first movable rod 602 to slide in the sleeve 601, and at the same time drive the gear 606 to rotate. The gear 606 can force synchronization and perform stable vertical movement.

[0022] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
