[0002] The quartz sand rotary heating process is indeed an advanced purification technology, which is mainly used in fields with extremely high requirements for material purity, such as high-tech industries such as optics, semiconductors and microelectronics. These industries have extremely high requirements for the quality of quartz materials, because any trace of impurities may seriously affect the performance and stability of the product.

[0003] In order to increase the output of high-purity quartz sand, flowing rotary heating of quartz sand is currently adopted, such as 201720711384.7, a horizontal quartz sand high-temperature gasification purification device; in order to increase the heat and purification output of high-purity quartz sand, two or more high-purity quartz sand heating flow tubes are adopted, and in order to make multiple high-purity quartz sand heating flow tubes rotate synchronously, a chain and multiple gear transmission are adopted, but the chain is prone to loosening due to factors such as manufacturing precision and assembly errors during production, assembly and long-term use. This loosening not only weakens the transmission efficiency, but also may cause instability in equipment operation, posing a potential threat to the overall performance and service life of the high-purity quartz sand heating purification device, and in severe cases may also cause equipment damage, thereby affecting production efficiency and product quality. Utility Model Content

[0004] The utility model aims to provide a high-purity quartz sand heating and purification device to solve the problems of decreased transmission efficiency and unstable equipment operation caused by loose chains in the high-purity quartz sand heating and purification device.

Specific embodiments

[0025] The following further describes the present utility model in conjunction with embodiments.

[0026] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement of the method of the present utility model under the premise of the conception of the present utility model belongs to the protection scope required by the present utility model.

[0027] Please refer to Figure 1 , the present utility model provides a high-purity quartz sand heating and purification device, including a base 10, a heating box 20 is arranged on the top of the base 10, the heating box 20 adopts an electric heating method, a quartz glass tube 210 is rotatably arranged in the heating box 20, both ends of the quartz glass tube 210 extend out from both ends of the heating box 20, a driving mechanism 30 is arranged on one side of the heating box 20, a supporting wheel 40 is arranged on the side of the heating box 20 away from the driving mechanism 30, and both ends of the quartz glass tube 210 are respectively connected to a feeding device and a cooling device.

[0028] Please refer to Figure 1-3 , on one side of the base 10 close to the driving mechanism 30, an "L"-shaped mounting plate 110 is connected, and the mounting plate 110 and the side of the base 10 close to the driving mechanism 30 enclose a mounting groove 1101, and the driving mechanism 30 is arranged in the mounting groove 1101.

[0029] Please refer to Figure 1-4 , the driving mechanism 30 includes a driving motor 310, a driving gear 320, and a driven gear 330; the driving motor 310 is installed in the mounting groove 1101, the driving gear 320 is installed on the output shaft of the driving motor 310, the number of driven gears 330 is two, and the two driven gears 330 are in transmission connection with the driving gear 320 through a chain 340, and the two driven gears 330 are respectively installed on the two quartz glass tubes 210.

[0030] Please refer to Figure 1-4 Figure 1-4 , the driving mechanism 30 further includes an adjusting gear 350. The adjusting gear 350 is rotatably sleeved on a connecting shaft 351. The connecting shaft 351 is connected to an adjusting plate 360. The driving gear 320 and the driven gear 330 are arranged in a triangle. The adjusting gear 350 is meshed with the chain 340, and the adjusting gear 350 presses against and bends the chain 340. The middle part of the adjusting plate 360 is movably sleeved on a middle shaft 361. The middle shaft 361 is connected in an installation groove 1101. A connecting block 370 is connected in the installation groove 1101. An elastic member 380 is connected between one end of the adjusting plate 360 away from the adjusting gear 350 and the side of the connecting block 370 close to each other.

[0031] The adjusting gear 350 is rotatably sleeved on the connecting shaft 351 and adjusts the tension of the chain 340 through meshing connection with the chain 340. Since the chain 340 may become loose due to manufacturing precision, assembly error, etc. during the transmission process, the adjusting gear 350 can timely adjust the tension of the chain 340 to maintain the stability and reliability of the transmission.

[0032] The combined use of the elastic member 380 and the adjusting gear 350 can significantly improve the transmission precision and stability. The elastic member 380 absorbs errors and impacts, while the adjusting gear 350 ensures that the chain 340 maintains an appropriate tension. The two work together to make the transmission system more stable and reliable.

[0033] Please refer to Figure 2 Figure 2 , one end of the quartz glass tube 210 away from the driving mechanism is arranged between two supporting wheels 40.

[0034] Please refer to Figure 5 Figure 5 , a plurality of protrusions 211 are arranged on the inner wall of the quartz glass tube 210. When the quartz glass tube 210 rotates, the protrusions 211 can better drive the quartz sand to turn over.

[0035] Please refer to Figure 3 Figure 3 , a reserve power source 50 is arranged in the installation groove 1101. The reserve power source 50 can supply power to the driving motor 310 alone when the factory area has a power outage. Since the quartz glass tube 210 is a special process quartz glass tube, the production cost is relatively high. When the temperature reaches 1200 degrees Celsius during heating of this device, the quartz glass tube 210 will be locally softened at this time. If the driving motor cannot operate due to a sudden power outage in the factory area and the quartz glass tube remains in a fixed posture, it will sag under the action of gravity and may even cause the quartz glass tube 210 to break in severe cases. For this reason, when there is a power outage, the reserve power source 50 supplies power to the driving motor 310, and the driving mechanism continues to keep the quartz glass tube 210 rotating at a constant speed and slowly, thereby reducing the local stress concentration caused by staying in a fixed posture for a long time. Uniform force application helps to maintain the shape stability of the quartz glass tube.

[0036] Working principle and usage process of the utility model: The device is arranged obliquely left and right. During use, quartz sand enters from the left side of the quartz glass tube 210 through the blanking device. By starting the drive motor 310, the drive motor 310 drives the driving gear 320 to rotate. The driving gear 320 drives two driven gears 330 to rotate through the chain 340. The two driven gears 330 drive the two quartz glass tubes 210 to rotate. The quartz sand moves to the right under the tumbling of the quartz glass tube 210 and its own gravity, and the quartz sand flows out from the right port of the quartz glass tube 210 and enters the cooling device.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
