Description

Technical Field

[0001] The utility model relates to the technical field of quartz material processing equipment, in particular to a high-temperature furnace tube for high-purity quartz material. Background Art

[0002] Processing high-purity quartz materials requires the use of high-temperature resistant furnace tubes to ensure that the furnace tubes themselves will not deform or react chemically when the materials are heat treated or processed in a high-temperature environment, and at the same time provide a stable heating environment. The processing of high-purity quartz materials usually needs to be carried out in an inert gas or vacuum environment to avoid contamination and oxidation by impurities. Vacuum furnaces provide a stable vacuum environment and can heat quartz materials at high temperatures. They are usually used in processing processes with high precision and high quality requirements, such as single crystal growth, annealing of oxidized quartz parts, etc.

[0003] There are many existing technologies for high temperature furnace tubes, such as:

For example, the quartz furnace tube that can extend the service life proposed in the above patent is an one-piece design, and no effective solution is given to the above problems.

[0006] In view of this, we propose a high-temperature furnace tube for high-purity quartz materials, which drives the working component and the clamping component to be clamped through the provided driving component. On the one hand, it realizes the sealing of the furnace tube during operation, and on the other hand, it can also ensure the convenience when adding and removing materials. Utility Model Content

[0030] Working principle: When the high-temperature furnace tube for high-purity quartz material provided in the utility model is used, the quartz material is processed and purified through the cavity formed inside the set working component 10; the working component 10 is then driven to rotate by the driving component 20 to ensure that the quartz is heated evenly and at the same time improve the consistency of the working component 10 and the driving component 20 when rotating; the clamping component 30 is used to automatically lock the working component 10 itself when the working component 10 drives the driving component 20 to rotate; finally, the position of the heating source when heating the furnace tube is adjusted by the adjusting component 40.

[0031] In order to process and purify the quartz material, the working component 10 includes a main furnace body 11, a pair of side furnace bodies 12 are symmetrically arranged on both sides of the main furnace body 11, slots 13 are opened at both ends of the main furnace body 11, and plugs 14 are fixedly connected to the ends of the two side furnace bodies 12 close to the main furnace body 11. The inner diameter of the cavity in the side furnace body 12 away from the end of the main furnace body 11 is smaller than the inner diameter of the cavity in the side furnace body 12 close to the end of the main furnace body 11; a ramp is formed inside the side furnace body 12, so that the quartz material added to the inner cavity is gathered in the main furnace body 11 under the action of gravity, so that it can be heated and purified by the heat source.

[0032] Taking into account the need to ensure that the quartz is heated evenly and to improve the consistency of the rotation of the working component 10 and the driving component 20; therefore, the driving component 20 includes a gear 21 that is clamped to the end of the side furnace body 12 away from the main furnace body 11, and a driving motor 22 is provided on the side of the gear 21 away from the side furnace body 12, and the output shaft of the driving motor 22 and the axis of the gear 21 are fixedly connected; after the quartz material is added to the inner cavity, the power supply of the driving motor 22 is turned on, and the driving motor 22 drives the gear 21 coaxially connected thereto to rotate, and the gear 21 then drives the side furnace body 12 clamped thereto to rotate.

[0033] In order to achieve automatic locking of the working component 10 when the working component 10 drives the driving component 20 to rotate, the clamping component 30 includes a pair of driven rings 32 fixedly connected to the inner side walls of the two slots 13 and a pair of active rings 31 fixedly connected to the outer side walls of the two plugs 14, and the two active rings 31 and the driven rings 32 are all centrally symmetrical; the active ring 31 arranged in the side furnace body 12 clamped with the gear 21 is driven by the driving motor 22 to rotate, and then is screwed into the driven ring 32 at one end of the main furnace body 11, and the active ring 31 at the other end of the main furnace body 11 is screwed into the driven ring 32 at the other end of the side furnace body 12 as the main furnace body 11 rotates, so that the main furnace body 11 and the two side furnace bodies 12 can be automatically tightened with each other during operation.

Although its hardness is relatively high, in some applications, due to its special crystal structure, it can show certain friction properties; after the power is turned on, the adjustment motor 44 drives the pulley 43 coaxially connected thereto to rotate, and under the action of the friction between the pulley 43 and the slide rail 41, the drive slide seat 42 drives the mounting seat 45 to move on the slide rail 41, thereby adjusting the position of the heating source on the mounting seat 45.

[0035] The high-temperature furnace tube for high-purity quartz material provided in the utility model is used to process and purify the quartz material through the cavity formed inside the working component 10. Specifically, a ramp is formed inside the side furnace body 12, so that the quartz material added to the inner cavity is gathered into the main furnace body 11 under the action of gravity, so that it can be heated and purified by the heating source; the driving component 20 is then used to drive the working component 10 to rotate, so as to ensure that the quartz is heated evenly and improve the consistency of the working component 10 and the driving component 20 when they rotate. Specifically, after the quartz material is added to the inner cavity, the power supply of the driving motor 22 is turned on, and the driving motor 22 drives the gear 21 coaxially connected thereto to rotate, and the gear 21 then drives the side furnace body 12 connected thereto to rotate; the clamping component 30 is used to make the driving component 20 rotate when the working component 10 drives the driving component 20 to rotate. The working component 10 automatically locks itself. Specifically, the active ring 31 arranged in the side furnace body 12 engaged with the gear 21 is driven by the driving motor 22 to rotate, and then is screwed into the driven ring 32 at one end of the main furnace body 11.
