[0003] After the preliminary treatment, the quartz sand enters the high-temperature purification furnace for purification. The process is as follows: the feeding equipment transports the quartz sand material to the purification tube in the purification furnace. Under high temperature conditions, the high-purity quartz sand raw material and the purified gas are fully mixed and reacted to reduce the impurity elements to achieve the purpose of purification.

[0004] Usually there is a single purification tube, which is set in the middle of the furnace. After the quartz sand material in the furnace tube is purified, it is unloaded for cooling, reloaded and then purified at high temperature. This cycle runs with low efficiency.

[0005] The two ends of the purification tube are set at the two ends outside the furnace body and supported by a tugwheel. The tugwheel abuts against the outer ring surface of the roller on the purification tube, and the friction transmission rotates. The furnace tube is in a high temperature environment. Under the action of heat conduction, the temperature of the roller is high, and the friction between the tugwheel and the roller generates heat. In a high temperature working environment, the tugwheel and the roller wear out quickly, affecting the transmission effect.

[0030] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0031] like Figure 1 As shown, a high-temperature purification furnace comprises a furnace shell 1 with a furnace chamber inside, at least two furnace tubes 2 are arranged inside the furnace shell 1, the furnace tubes 2 are extended along the length direction of the furnace shell 1, and both ends of the furnace tubes 2 extend to the outside of the furnace shell 1 and are respectively constructed as a loading end 3 and a unloading end 4.

[0032] The material (quartz sand) enters the furnace tube 2 from the feeding end 3. The furnace provides a high temperature environment for the furnace tube 2, and the purified gas is provided through the gas device. The purified gas reacts with the quartz sand in the furnace tube to reduce the impurity elements to achieve the purpose of purification. The continuous rotation of the furnace tube 2 helps the quartz sand and the purified gas to fully contact and mix, thereby improving the purification effect.

[0033] The driving mechanism 5 and the transmission mechanism 6 are arranged in pairs, and a set of the driving mechanism 5 and the transmission mechanism 6 is arranged on at least one side of the loading end and the unloading end of the furnace shell 1, and the driving mechanism 5 is used as a power source to drive the furnace tube 2 to rotate through the transmission mechanism 6. No matter how many furnace tubes 2 are arranged, all the furnace tubes 2 keep rotating synchronously.

[0034] For ease of understanding, the transmission operation is described in detail below by taking two furnace tubes 2 arranged in parallel as an example.

[0035] Specifically, refer to the attached Figure 2 , two furnace tubes 2 are arranged in parallel. Figure 3 As shown in FIG. 1 , the transmission mechanism 6 includes a chain 61 , a main sprocket 62 and a transmission wheel. On the same end side of the furnace shell 1 , one furnace tube 2 matches a set of transmission wheels and the main sprocket 62 .

[0036] The transmission wheel includes a tug wheel 64 and a roller 65. The roller 65 is coaxially mounted on the feeding end 3 or the unloading end 4. The tug wheel 64 and the main sprocket 62 are coaxially mounted on a rotating shaft 66 mounted on a support frame.

[0037] The driving mechanism 5 is used as a power source, and the transmission circuit formed by the combination of the chain 61 and the main sprocket 62 drives the furnace tube 2 to rotate around its own central axis through a plurality of transmission wheels. Figure 3 At least two guide sprockets 63 are arranged between the two furnace tubes 2 to guide the chain 61 to avoid interference between the running components.

[0038] When the transmission mechanism 6 is only provided on one side, the loading end 3 or the unloading end 4 on the other side is supported and driven by the tug 64. Therefore, on the same end side of the furnace shell 1, all the furnace tubes 2 are driven by the transmission loop of the same chain 61 to rotate synchronously around their own central axis to keep the purification process consistent.

[0039] In detail, the support frame includes a group of support plates 7 arranged in parallel, the rotating shaft 66 vertically passes through the support plates 7 on both sides, the tugboat 64 and the main sprocket 62 are coaxially installed on the rotating shaft 66 and rotate synchronously, and the driving mechanism 5 is set as a motor, and the driving end of the motor is connected to the rotating shaft 66.

[0040] The tugboat 64 is installed between the support plates 7 on both sides, and the main sprocket 62 is installed on the outer side of the support plate 7 on one side.

[0041] In addition, a cooling water channel 9 is constructed at the bottom of the tugboat 64 through a partition 8, and the partition 8 is in contact with at least the side walls of the support plate 7 on both sides. The tugboat 64 in the transmission mechanism 6 is cooled by water through the cooling water channel 9.

[0042] In one embodiment, the partition 8 is configured as an independent pipeline. Figure 4An independent pipeline is arranged between each group of support plates 7 to provide a cooling pipeline.

[0043] In another embodiment, the partition 8 is configured as a continuous pipe, and the cavity inside the pipe forms a cooling water path; the continuous pipe is continuously extended with each group of support plates 7 as a support node, and all tugboats 64 share a cooling water path, see the attached Figure 5 Schematic diagram of .

[0045] Regardless of whether the partition 8 is configured as a continuous pipe or multiple independent short pipes, the side walls of the pipe are in close contact with the side walls of the support plate 7 to form a low-temperature semi-enclosed structural environment to cool the tugboat 64 placed therein. In addition, the close contact of the wall surface can increase the contact area and improve the heat conduction efficiency.

[0046] Furthermore, a thin layer plate 10 is arranged on the top of the partition member 8 , and the thin layer plate 10 is arranged as a box-shaped strip groove frame, the bottom of the tugboat 64 is accommodated in the box-shaped strip groove frame, and the side plates on both sides of the thin layer plate 10 are in contact with the support plate 7 .

[0047] The bottom surface of the thin layer plate 10 is in direct or indirect contact with the surface of the partition member 8, such as the attached Figure 3 As shown in , a schematic diagram of indirect contact is provided.

[0048] The cooling water channel at the bottom provides a cooling source, which changes the support plate 7 and the thin layer plate 10 that are most directly or indirectly attached thereto into a low-temperature environment, shortens the cooling distance between the tugboat 64 and the cooling source, and improves the cooling effect.

[0049] The utility model provides at least two furnace tubes in the purification furnace, and the furnace tubes rotate synchronously through the transmission mechanism, so that more quartz sand materials can be purified at the same time, and the processing efficiency is improved. Moreover, all the furnace tubes share a set of transmission mechanism and driving mechanism, and the equipment components are simplified.
