[0027] The following is in conjunction with the appendix Figure 1-9 The present invention will be further described below.

[0028] To address the problems existing in the background technology, this application proposes the following technical solution: A high-temperature purification device for quartz sand includes a reactor 1. A heat insulation cover 27 is fixedly connected to the outside of the reactor 1. A heat insulation cavity 28 is provided in the heat insulation cover 27 and filled with heat insulation cotton. A conveying assembly is provided outside the reactor 1 for conveying quartz sand into the reactor 1. An electromagnetic heating coil 29 is fixedly connected to the outside of the reactor 1. One end of the reactor 1 is an open structure, and a side cover 6 is provided at the opening. A sealing ring 9 is fixedly connected to the outside of the side cover 6. Multiple sets of slots 10 are provided outside the sealing ring 9. Multiple sets of connecting plates 7 are fixedly connected to one end of the reactor 1. A hanging ring 8 is fixedly connected to the outside of the connecting plate 7. A locking assembly for locking the hanging ring 8 is also provided outside the side cover 6. A gas source and a vacuum filtration assembly are also provided outside the reactor 1. The reactor 1, as the core container for high-temperature purification of quartz sand, is made of a special alloy material that is resistant to high temperature and corrosion and can withstand chemical reactions and pressure changes under high-temperature conditions. The externally fixed heat insulation cover 27 forms an effective heat insulation barrier through the internal heat insulation cavity 28 and the filled heat insulation cotton, reducing the heat loss of the reactor 1 when it is working at high temperature. This not only improves energy utilization efficiency, but also reduces the temperature outside the device, avoids burns to operators, and improves operational safety.

[0029] The conveying assembly automates the transport of quartz sand, eliminating the need for manual handling and feeding, thus reducing the risk of contamination from human contact. It also ensures the continuity and stability of the feeding process and facilitates control over the amount of quartz sand added. The electromagnetic heating coil 29 outside the reactor 1 uses electromagnetic induction heating, providing uniform and rapid heating. This allows for precise temperature control within the reactor 1, meeting the stringent temperature requirements of high-temperature purification, and is more energy-efficient and environmentally friendly compared to traditional heating methods.

[0030] The side cover 6 at the opening of reactor 1, in conjunction with the sealing ring 9, effectively seals reactor 1, preventing gas leakage and the entry of external impurities at high temperatures. The groove 10 on the outside of the sealing ring 9 engages with the structure at the end of reactor 1, further enhancing the sealing performance. The hanging ring 8 on the connecting plate 7 engages with the locking assembly of the side cover 6, ensuring that the side cover 6 will not loosen under high temperature and high pressure conditions, guaranteeing the safety of the purification process. The gas source provides reactor 1 with the necessary inert or reactive gas, while the vacuum filter assembly evacuates reactor 1 to a vacuum state, eliminating air interference and creating a pure reaction environment for the high-temperature purification of quartz sand.

[0031] In this embodiment, multiple sets of bases 14 are fixedly connected to the outside of the side cover 6. A base plate 17 is fixedly connected to the base 14, and a rotating cover 15 is rotatably connected to the base plate 17. A hanging rod 16 is rotatably connected to the outside of the rotating cover 15. A plug-in plate 18 is fixedly connected to the base plate 17, penetrating the rotating cover 15. The plug-in plate 18 has a through hole 19. A side plate 12 is fixedly connected to the outside of the side cover 6, and a positioning screw 13 is threaded onto the outside of the side plate 12. A protruding ring 11 is fixedly connected to one end of the side cover 6. The base 14 outside the side cover 6 provides stable support for the base plate 17. The rotating cover 15 rotatably connected to the base plate 17 can be flexibly adjusted in angle. The hanging rod 16 outside the rotating cover 15 can cooperate with the hanging ring 8 of the reactor 1. By rotating the rotating cover 15, the hanging rod 16 is hooked onto the hanging ring 8, thus achieving the initial fixation of the side cover 6 to the reactor 1. This connection method is simple to operate and facilitates the quick installation and positioning of the side cover 6.

[0032] The insert plate 18 on the base plate 17 passes through the rotating cover 15, providing guidance and limiting for the rotation of the rotating cover 15 and preventing excessive rotation. The through hole 19 in the insert plate 18 engages with the positioning screw 13 on the side plate 12. After the hanging rod 16 is engaged, rotating the positioning screw 13 to pass through the through hole 19 can fix the rotating cover 15, preventing it from loosening during device operation and ensuring a stable sealing effect of the side cover 6. The positioning screw 13 adopts a threaded connection, which is secure and easy to disassemble; locking or unlocking can be completed simply by rotating it.

[0033] The protruding ring 11 at one end of the side cover 6 can be inserted into the opening of the reactor 1 when the side cover 6 is closed, forming a double sealing structure with the sealing ring 9, enhancing the sealing performance of the reactor 1 and preventing high-temperature gas leakage. This multi-fixing and sealing design ensures both the firmness of the side cover 6 installation and the sealing performance of the reactor 1 under high temperature and high pressure environments, providing stable reaction conditions for quartz sand purification. At the same time, it facilitates quick installation and removal of the side cover 6 by operators, improving equipment maintenance efficiency.

[0034] In this embodiment, the conveying component is a screw conveyor 2. A feed hopper 3 is fixedly connected to the outside of the screw conveyor 2, and a discharge pipe 4 is fixedly connected to the output end of the screw conveyor 2. One end of the discharge pipe 4 extends into the reactor 1, and a first valve 5 is fixedly connected in the discharge pipe 4. The screw conveyor 2 enables continuous and uniform conveying of quartz sand. When its blades rotate, they can push the quartz sand forward along the conveying pipe, avoiding material blockage and ensuring smooth feeding. The large opening design of the feed hopper 3 facilitates manual or mechanical feeding, reducing waste and pollution caused by quartz sand spillage.

[0035] The output end of the screw conveyor 2 feeds quartz sand into the reactor 1 through the discharge pipe 4. The discharge pipe 4 extends into the reactor 1 to prevent quartz sand from accumulating at the inlet and ensure accurate feeding. The first valve 5 in the discharge pipe 4 can be quickly closed after the conveying is completed, isolating the reactor 1 from the outside world, preventing the leakage of high-temperature gas or gaseous media inside the reactor 1, and preventing outside air from entering and affecting the purification effect.

[0036] This automated conveying method replaces manual feeding, reducing the labor intensity of operators and precisely controlling the feed rate to meet the needs of different purification batches. The screw conveyor auger 2 has a simple structure, is easy to maintain, and is suitable for conveying granular materials such as quartz sand, ensuring the continuity and stability of the purification process and improving overall production efficiency.

[0037] In this embodiment, the gas source includes a gas tank 26 and a second pipe 24 fixedly connected to the output end of the gas tank 26. A third valve 25 is fixedly connected to the second pipe 24. The vacuum filtration assembly includes a fixed vacuum pump 22 and a first pipe 20 fixedly connected to the input end of the vacuum pump 22. The second pipe 24 is fixedly connected to the first pipe 20, and the first pipe 20 is fixedly connected to the reactor 1. A second valve 21 is fixedly connected to the first pipe 20. A filter cartridge 23 is fixedly connected to the output end of the vacuum pump 22. The filter cartridge 23 is provided with a high-temperature ceramic filter layer and an activated carbon adsorption layer. The gas tank 26 in the gas source is used to store the inert gas (such as argon) or reactive gas (such as chlorine) required for purification. The gas is transported to the reactor 1 through the second pipe 24. The third valve 25 in the second pipe 24 can precisely control the gas delivery and shut-off, which facilitates the adjustment of gas flow rate and pressure to meet the gas environment requirements of different purification stages.

[0038] The vacuum pump 22 of the vacuum filtration assembly can evacuate the reactor 1 to a vacuum state, removing impurities such as air and moisture, creating an oxygen-free environment for the high-temperature purification of quartz sand, and preventing impurities from affecting the purification purity. The second valve 21 in the first pipeline 20 can control the vacuum extraction and closing, and works with the third valve 25 to switch between vacuum and gas filling. The fixed connection between the second pipeline 24 and the first pipeline 20 allows gas to enter the reactor 1 through the same pipeline, simplifying the pipeline design, reducing the number of interfaces, and lowering the risk of leakage.

[0039] In the filter cartridge 23 at the output end of the vacuum pump 22, a high-temperature ceramic filter layer can filter solid particles produced by the reaction, and an activated carbon adsorption layer can adsorb harmful gases and odors, ensuring that the discharged gas meets environmental protection standards and avoids environmental pollution. This combination of gas source and vacuum filter components allows for flexible control of the gas environment inside the reactor 1, ensuring that the quartz sand undergoes a pure reaction at high temperatures, improving purification quality, and simultaneously meeting environmental protection requirements.

[0040] In this embodiment, it should also be noted that a motor can be fixedly connected to the outside of the reactor 1, and a stirring blade can be rotatably installed inside the reactor 1. The output end of the motor is fixedly connected to the stirring blade, so that the motor drives the stirring blade to rotate, thereby turning the quartz sand over and allowing the quartz sand to react fully.

[0041] The usage method of this embodiment is as follows:

[0042] Quartz sand is conveyed into reactor 1 via screw conveyor 2. After conveying is completed, the first valve 5 is closed for sealing.

[0043] Then, close the third valve 25, open the second valve 21, and then use the vacuum pump 22 to evacuate the reactor 1.

[0044] After evacuation, close the second valve 21 and open the third valve 25 to allow the inert gas (argon or chlorine) in the gas tank 26 to be delivered to the reactor 1. Once the delivery volume is reached (a flow meter can be installed on the second pipe 24), close the third valve 25.

[0045] Finally, simply turn on the electromagnetic heating coil 29 to heat the reactor 1, and the high-temperature purification of the quartz sand can be completed.

[0046] After completion, open the second valve 21, use the vacuum pump 22 to extract the gas after reaction, and filter it through the filter cartridge 23 before discharging.

[0047] Next, rotate and remove the positioning screw 13 so that the positioning screw 13 is no longer inserted into the through hole 19. Then rotate the rotating cover 15 so that the hanging rod 16 on the outside of the rotating cover 15 is no longer hooked onto the hanging ring 8, so that the side cover 6 can be removed. After removing the side cover 6, the quartz sand in the reactor 1 can be removed by using a tool (shovel).
