Description

Technical Field

[0001] This utility model relates to the field of quartz sand purification technology, specifically to a purification device. Background Technology

[0002] Quartz sand purification typically employs high-temperature heating to cause impurities in the quartz sand to undergo physical or chemical changes at high temperatures, thereby separating them from the quartz. To further improve the purity of quartz sand, existing technologies often utilize a two-stage heating furnace structure. This is achieved by setting different temperatures or injecting specific chemical gases into the two reactors, resulting in better purification. However, in existing technologies, the two reactors are often connected in an open manner, meaning that the quartz sand exiting the first reactor falls into the second reactor's inlet under its own weight. This structure leads to the problem of easy leakage of chemical gases within the reactors. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] refer to Figures 1 to 3The purification apparatus 100 according to an embodiment of the present invention includes a first reactor 101, a second reactor 102, and a connecting assembly 103. A first heating tube 201 is disposed within the first reactor 101, and the first heating tube 201 includes an outlet end 202. The second reactor 102 is disposed downstream of the first reactor 101, and a second heating tube 203 is disposed within the second reactor 102, and the second heating tube 203 includes an inlet end 204. The connecting assembly 103 has a cavity 303 and is disposed between the first reactor 101 and the second reactor 102. The outlet end 202 is sealed to the upper end of the connecting assembly 103, and the inlet end 204 is sealed to the lower end of the connecting assembly 103. The outlet end 202 and the inlet end 204 communicate with the cavity 303, which is isolated from the atmospheric environment. Both the first heating tube 201 and the second heating tube 203 are used to hold quartz sand. The chemical gas also flows through the first heating tube 201 and the second heating tube 203 and reacts with the impurities in the quartz sand at high temperature. Therefore, a connecting component 103 is added between the first reactor 101 and the second reactor 102, and the outlet end 202 of the first heating tube 201 and the inlet end 204 of the second heating tube 203 are sealed to the connecting component 103. The cavity 303 in the connecting component 103 is isolated from the atmospheric environment, which effectively improves the problem of gas leakage at the connection.

[0028] It should be noted that the reference Figure 1 In some embodiments of this utility model, the conveying and processing direction of the quartz sand is as follows: Figure 1 As shown in the left-to-right direction, a further reactor can be added downstream of the second reactor 102. Connecting an additional reactor downstream of the second reactor 102 can further improve the purification quality. Through staged treatment, impurities are initially removed, followed by deep purification, optimizing temperature and time control, and reducing side reactions. It can also selectively remove specific impurities, enhance compound recovery and reuse, save costs, and reduce pollution. Furthermore, staged treatment helps ensure consistent product quality, facilitates monitoring and maintenance, and has strong scalability, allowing for further improvements in purification levels as needed, thereby significantly improving the quality and application performance of the quartz sand.

[0029] It should be noted that chlorine is preferably used as the chemical gas mentioned above. Chlorine can react with various metallic and non-metallic impurities to generate volatile chlorides, thereby effectively separating them from the quartz sand. Furthermore, chlorine is easy to store and transport, has wide industrial applications with mature technical support, and allows for adjustment of reaction conditions for different types of impurities, offering great flexibility. In some embodiments, appropriate amounts of oxygen, nitrogen, or other gases may also be introduced to protect the reaction environment or promote the oxidation reaction.

[0030] refer to Figure 3In some embodiments of this utility model, the first heating tube 201 is rotatably disposed in the first reactor 101, and the second heating tube 203 is rotatably disposed in the second reactor 102. The outlet end 202 is rotatably connected to the connecting component 103, and the inlet end 204 is rotatably connected to the connecting component 103. In the quartz sand purification process, designing the heating tube containing the quartz sand in the reactor as a rotatable structure can significantly optimize the purification effect. By rotating the heating tube, the quartz sand can be dynamically mixed when heated, avoiding uneven heating caused by static accumulation, thereby reducing impurity residue or incomplete reaction caused by temperature differences. Simultaneously, the contact area and frequency between the quartz sand and the reaction gas (such as chlorine) increase during rotation, promoting the full chlorination and volatilization of impurity elements (such as metal ions), and improving the overall reaction efficiency. Furthermore, rotation can prevent the quartz sand from clumping or adhering to the tube wall due to prolonged static storage at high temperatures, ensuring thermal conductivity stability and reducing subsequent cleaning difficulty, ultimately achieving more uniform purification quality and higher product consistency.

[0031] refer to Figure 3 and Figure 4 In some embodiments of this utility model, the purification device 100 further includes multiple sealing rings 302. The sealing rings 302 are disposed at the connection between the outlet end 202 and the connecting assembly 103, and at the connection between the inlet end 204 and the connecting assembly 103. An elastic element 401 is radially disposed within the sealing ring 302. The elastic force of the elastic element 401 drives the inner circumferential surface of the sealing ring 302 to adhere to the inlet end 204, and the elastic force of the elastic element 401 drives the inner circumferential surface of the sealing ring 302 to adhere to the outlet end 202. The sealing ring 302 with the internal elastic element 401 can further improve the sealing performance at the connection between the connecting assembly 103 and the inlet end 204 and the outlet end 202. Specifically, by fixing the outer circumferential surface of the sealing ring 302, the elastic force of the elastic element 401 is applied evenly to the inner circumferential surface of the sealing ring 302, thereby improving the sealing performance of the inner circumferential surface of the sealing ring 302 at the connection and preventing gas leakage.

[0032] refer to Figure 2 and Figure 3 In some embodiments of this utility model, two or more first heating tubes 201, connecting components 103, and second heating tubes 203 are provided. Both first heating tubes 201 are disposed within the first reactor 101, and both second heating tubes 203 are disposed within the second reactor 102. Each connecting component 103 connects one first heating tube 201 and one second heating tube 203. This allows for the simultaneous processing of more raw materials, with multiple tubes working in parallel, shortening the production cycle. Furthermore, if a first heating tube 201 or second heating tube 203 requires maintenance or cleaning, the other tubes can continue operating, preventing the entire production line from halting.

[0033] refer to Figure 2 and Figure 3 In some embodiments of this utility model, two heating tubes 201, connecting components 103, and second heating tubes 203 are provided. The purification device 100 also includes a transmission component, which includes a drive member 301, two gears 209, two gear rings 210, two pulleys 211, and a belt 212. The output end of the drive member 301 is connected to the gear 209, the gear 209 meshes with the gear ring 210, the gear 209 and the pulleys 211 are coaxially arranged, the two pulleys 211 are connected by the belt 212, the output end of the drive member 301 is connected to any one of the gears 209, and the drive member 301 is used to drive the gear 209 to rotate, so that the gear ring 210 meshing with it and the coaxially arranged pulleys 211 rotate. The pulley 211 drives the other pulley 211 to rotate through the belt 212 and drives another set of gears 209 and gear rings 210 to rotate. The gear rings 210 are fixedly installed on the outer peripheral surfaces of the two inlet ends 204 and / or the outer peripheral surfaces of the two outlet ends 202. The specific principle is as follows: the driving component 301 first drives a gear 209 to rotate, which in turn drives the gear ring 210 and the coaxially connected pulley 211 to rotate. The pulley 211 transmits power to the other pulley 211 through the belt 212. The second pulley 211 then drives the second gear ring 210 to rotate through the coaxial gear 209. The gear ring 210 is fitted onto the inlet end 204 or the outlet end 202, thereby enabling one driving component 301 to drive the two first heating tubes 201 or the second heating tubes 203 to rotate simultaneously. This results in high power efficiency and a simple layout.

[0034] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the connecting assembly 103 includes a connecting pipe 205 and a fastening ring 206. A first heating pipe 201 and a second heating pipe 203 are connected to the connecting pipe 205. The fastening ring 206 is sleeved on the outer circumferential surface of the connecting pipe 205 to prevent expansion and deformation. The fastening ring 206, by clamping the outer circumference of the connecting pipe 205, can prevent deformation of the connecting pipe 205 due to high temperatures, effectively extending the service life of the connecting pipe 205 and saving on component maintenance and replacement costs. It should be noted that, according to reference... Figure 2 In some embodiments of this utility model, the fastening ring 206 can be sleeved on the upper and lower ends of the connecting pipe 205, which can further improve the fastening effect and the uniformity of force on the connecting pipe 205.

[0035] refer to Figure 1In some embodiments of this invention, from upstream of the first reactor 101 to downstream of the second reactor 102, the first reactor 101 and the second reactor 102 gradually tilt downwards. The tilt angle allows the quartz sand to flow naturally downwards by gravity, without the need for additional power, reducing equipment wear and energy consumption, while also preventing material accumulation and jamming.

[0036] In some embodiments of this invention, a gas inlet is provided at the downstream end of the second reactor 102, and a gas outlet is provided at the upstream end of the first reactor 101. The gas inlet is connected to the second heating tube 203, and the gas outlet is connected to the first heating tube 201. The gas inlet and the gas outlet are used for injecting and discharging the purified gas, respectively. The purified gas (such as chlorine) flows upward from the downstream gas inlet and is discharged from the upstream gas outlet, forming a countercurrent contact with the falling quartz sand, which can prolong the reaction time and improve the impurity removal efficiency.

[0037] refer to Figure 2 and Figure 3 In some embodiments of this invention, the purification apparatus 100 further includes a thermometer 207, which is installed in the second reactor 102 and used to detect the temperature inside the second reactor 102. Since the second reactor 102 is located downstream and needs to process trace impurities not completely removed by the first reactor 101, its reaction temperature, gas concentration, and other parameters require more stringent control. For example, the volatilization of certain metal chlorides requires a specific temperature window, and the thermometer 207 can prevent temperature fluctuations from causing impurity residue. In some embodiments of this invention, the outer surface of the thermometer 207 is provided with a transparent cover, which can protect the thermometer 207 from dust without affecting the observation of temperature values.

[0038] refer to Figure 2 and Figure 3 In some embodiments of this invention, at least a portion of the outer shell of the second reactor 102 is a transparent section 208, which is used to observe the interior of the second reactor 102 from the outside. Similarly, since the second reactor 102 is located downstream, it needs to handle trace impurities that were not completely removed by the first reactor 101. The transparent window allows direct observation of whether the quartz sand flow is uniform, whether there is local agglomeration, or abnormal gas distribution, ensuring sufficient reaction. In some embodiments of this invention, both the temperature sensor 207 and the transparent section 208 can be located in the first reactor 101. (See reference...) Figure 3 In some embodiments of this utility model, the driving member 301 is disposed at the downstream end of the first reactor 101 and / or the upstream end of the second reactor 102, and the transparent part 208 is integrated with the driving member 301, so that the internal environment of the reactor can also be observed. Furthermore, the transparent part 208 can also be configured as an anti-fog layer, which is not only transparent but also prevents fog from affecting the observation of the inside of the reactor.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
