Description

Technical Field

[0001] This invention relates to the field of calcining furnace technology, specifically to a curved diameter quartz calcining furnace tube for a high-quality quartz calcining furnace. Background Technology

[0002] Quartz sand is quartz particles produced by processing quartz stone through crushing and screening. Quartz stone is a non-metallic mineral, whose main mineral component is silicon dioxide (SiO2). Quartz sand can be classified according to quality into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, and silica powder, etc. The SiO2 content and impurity content vary among different types of quartz sand. For example, the SiO2 content of ordinary quartz sand is generally not less than 90%, while the SiO2 content of high-purity quartz sand is as high as 99.9% or more.

[0003] Quartz sand plays an indispensable role in many key industrial sectors, from basic glass manufacturing to high-tech semiconductor and photovoltaic industries. As a core raw material in the glass industry, quartz sand ensures the transparency and durability of glass products; in the ceramics and refractory materials fields, it enhances the high-temperature resistance and chemical stability of products; in the metallurgical industry, quartz sand is used as an additive to optimize alloy properties; it is also an important raw material in many other industries such as construction and chemicals. Especially in high-tech fields such as semiconductors and photovoltaics, high-purity quartz sand has become a key material for manufacturing core components such as integrated circuits and solar panels, driving innovation in these industries.

[0004] In the existing chlorination purification process of quartz sand, a calcination furnace is required to treat the quartz sand and chlorine gas at high temperatures. The chlorine gas reacts with the impurities in the quartz sand, and continuous calcination removes the impurities and improves the purity of the quartz sand. However, existing industry equipment is designed for the calcination process of natural quartz sand, requiring relatively low calcination temperatures and short residence times of the material in the calcination furnace. This makes it impossible to ensure the complete reproducibility of the calcination process, resulting in some quartz sand not being completely purified during the calcination process, thus reducing the purification rate of existing quartz sand. To address this, we provide a curved diameter quartz calcination furnace tube for high-quality quartz calcination furnaces. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention sets the existing quartz sand calcination pipe as a reducing pipe structure, with the calcination zone having a different diameter from the inlet and outlet ends. Furthermore, a 45-degree cross baffle is designed at the point where the diameters differ at both ends of the reducing pipe, ensuring that the calcined material is completely contained within the calcination zone.

[0017] 2. This invention reverses the positions of the air inlet and outlet, designs the outlet pipe to be constricted at the air inlet position, and discharges the material through the side wall at the same time. The air inlet channel and the discharge direction are deflected perpendicularly so that they do not interfere with each other, thereby reducing the dust discharged from the material.

[0018] 3. This invention achieves environmental protection and energy conservation by reusing the heat from the exhaust gas discharged from the calcining furnace.

[0019] 4. This invention controls the calcination temperature of the reducing furnace tube within a suitable temperature range, avoiding large temperature fluctuations that could cause thermal stress on the inner wall surface of the reducing furnace tube and accelerate lining peeling. At the same time, it inhibits the formation of liquid chloride salts and extends the service life of the reducing furnace tube. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides a technical solution: such as Figure 1 - Figure 8As shown, a curved diameter quartz calcining furnace tube for a high-quality quartz calcining furnace includes a base box 1, a calcining box 101 placed on the upper end of the base box 1, a protective cover 102 fastened to the upper end of the calcining box 101, and a discharge telescopic rod 104 for pushing the calcining box 101 to tilt up is provided on the inner wall of the base box 1 near the calcining box 101. When the material is transferred to the calcining furnace and calcined, the discharge telescopic rod 104 is activated to push the feeding end of the calcining box 101 to tilt up, thereby transferring the material in the curved diameter furnace tube 201 to the other feeding end of the calcining furnace. The calcination chamber 101 is equipped with a furnace tube component 2 for calcining and purifying quartz sand. The furnace tube component 2 includes a reducing furnace tube 201, and the inlet and outlet of the reducing furnace tube 201 are both set to half the diameter of the middle calcination section. A protective cylinder 205 is fixedly installed on the inner wall of the calcination chamber 101 near the reducing furnace tube 201. The protective cylinder 205 isolates the heat from the reducing furnace tube 201, preventing a large amount of heat loss and protecting other components in the overall calcination furnace. A heating ring 108 is fitted on the outer wall of the reducing furnace tube 201 to calcine and heat the material inside the reducing furnace tube 201. An exhaust ring 107 is rotatably fitted on the outer wall of one end of the reducing furnace tube 201. A three-way pipe 106 is fixedly installed on the upper end of the exhaust ring 107, and an exhaust pipe 105 is fixedly installed on the upper end of the three-way pipe 106. The exhaust pipe 105 is provided with a... A control component 3 is provided to detect and regulate the chlorine gas inlet speed, rotation speed, and calcination temperature of the reducing furnace tube 201. Specifically, when the material is heated into the reducing furnace tube 201, the electronic gas valve 303 is opened, and the material falls into the reducing furnace tube 201. The slope set at the different diameters at the inlet and outlet of the reducing furnace tube 201 keeps the heat-treated material in the calcination area, ensuring that the material remains in the calcination area to achieve 100% calcination physical treatment effect and improve the purification rate of quartz sand. At the same time, the control component 3 controls the temperature inside the reducing furnace tube 201, keeping the calcination temperature within a suitable range to avoid large temperature fluctuations that could cause thermal stress on the inner wall surface of the reducing furnace tube 201 and accelerate the peeling of the inner lining. It also inhibits the formation of liquid chloride salts and extends the service life of the reducing furnace tube 201.

[0034] An inlet pipe 109 is fixedly installed at the end of the reducing furnace tube 201 away from the outlet ring 107. An inlet box 110 is fixedly installed at the end of the inlet pipe 109 away from the reducing furnace tube 201. An inlet pipe 111 is fixedly installed at the side end of the inlet box 110 away from the inlet pipe 109. An exhaust pipe 105 passes through the side end of the inlet box 110 near the inlet pipe 111. The exhaust pipe 105 is laid inside the inlet box 110 in a serpentine bend. Specifically, when the hot waste gas after the calcination furnace heating and calcination purification reaction is transferred to the exhaust pipe 105 through the outlet ring 107, the exhaust pipe 105 heats the gas that enters the inlet box 110 through the inlet pipe 111. The gas is then transferred to the reducing furnace tube 201 through the inlet pipe 109, so that the heat of the hot waste gas discharged from the calcination furnace can be reused, which plays a role in environmental protection and energy saving.

[0035] Baffles 212 are installed at the diameter changes of the reducing furnace tube 201. These baffles 212 are semi-elliptical discs, welded at a 45-degree angle to the diameter changes of the reducing furnace tube 201, and are perpendicular to each other. The baffles 212 can block the heat-treated material inside the reducing furnace tube 201 within the calcination zone, ensuring that the material remains within the calcination zone to achieve a 100% calcination physical treatment effect. Agitator plates 21 are arrayed and installed on the inner wall of the calcination section of the reducing furnace tube 201. 4. Three stirring plates 214 are provided. An exhaust pipe 213 is fixedly installed at the feed port of the reducing furnace tube 201 near the gas outlet ring 107. The exhaust pipe 213 changes the feed end of the reducing furnace tube 201 to a double layer, so that when the calcining furnace starts to feed, the material enters through the inner wall of the exhaust pipe 213, and the gas is discharged through the interlayer between the reducing furnace tube 201 and the exhaust pipe 213, so that most of the calcining gas during hot calcination is discharged through the interlayer and enters the exhaust pipe 105.

[0036] Multiple exhaust holes 216 are arrayed on the outer wall of the furnace tube 201 near the exhaust ring 107. Multiple discharge holes 215 are arrayed on the end of the furnace tube 201 away from the exhaust holes 216. A discharge pipe 202 is rotatably sleeved on the outer wall of the discharge hole 215. A collector 203 is rotatably connected to the lower end of the discharge pipe 202, and the collector 203 is fixedly installed on the side of the base box 1. Specifically, the calcined and purified gas enters through the end of the furnace tube 201 away from the exhaust ring 107 and then exits from the exhaust holes 216, so that the material and gas are transported in opposite directions, increasing the reaction time of the material and thus improving the purification efficiency of the device. The discharge holes 215 allow the calcined and purified material to be discharged through the discharge holes 215, which are perpendicular to the air inlet, reducing the dust of the material.

[0037] A drive motor 211 is fixedly installed on the inner wall of the calcining chamber 101 near the exhaust ring 107. A drive disc 210 is fixedly installed at the output end of the drive motor 211. A driven disc 208 is rotatably installed on the outer wall of the calcining chamber 101 near the drive disc 210. The diameter ratio of the driven disc 208 to the drive disc 210 is three to one, reducing the resistance generated during the drive process of the drive motor 211. A transmission belt 209 is wound and connected to the outer walls of the drive disc 210 and the driven disc 208. A drive gear ring 206 is fixedly sleeved on the outer wall of the driven disc 208 near the calcining chamber 101, and a protective shell 103 is fixedly installed on the outer wall of the calcining chamber 101 near the drive gear ring 206. The driving gear ring 206 is meshed with a transmission gear 207. The side of the transmission gear 207 away from the driving gear ring 206 is meshed with a rotating gear ring 204. The rotating gear ring 204 is fixedly sleeved on the outer wall of the reducing furnace tube 201. Specifically, when the drive motor 211 is started to work, the driving disc 210 starts to rotate, causing the transmission belt 209 to drive the driven disc 208 to rotate. The driven disc 208 causes the driving gear ring 206 to drive the transmission gear 207 to rotate, and the transmission gear 207 drives the rotating gear ring 204 to rotate, thereby causing the reducing furnace tube 201 to rotate. This causes the material to continuously tumble during the calcination process, ensuring complete calcination and purification.

[0038] The control component 3 includes a temperature sensing ring 301, which is fixedly sleeved on the outer wall of the exhaust pipe 105. The temperature sensing ring 301 stores nitrogen gas that expands and contracts with temperature changes, which will not be described in detail here. A vent pipe 305 is fixedly installed on the side end of the temperature sensing ring 301. A pneumatic telescopic rod 306 is fixedly installed on the end of the vent pipe 305 away from the temperature sensing ring 301. An energized slider 307 is fixedly installed on the output end of the pneumatic telescopic rod 306. A resistance tube 308 is fixedly installed on the inner wall of the protective cover 102 near the energized slider 307, and the energized slider 307 is slidably sleeved on the outer wall of the resistance tube 308. Specifically, when the inside of the reducing furnace tube 201... When the temperature begins to decrease, the temperature of the exhaust gas transmitted from the exhaust pipe 105 decreases, causing the pneumatic telescopic rod 306 to retract. The energized slider 307 slides on the resistance tube 308, thereby improving the working efficiency of the heating coil 108 and reducing the rotation speed of the reducing furnace tube 201. When the internal temperature of the reducing furnace tube 201 begins to rise, the temperature of the exhaust gas transmitted from the exhaust pipe 105 increases, causing the pneumatic telescopic rod 306 to extend. The energized slider 307 slides on the resistance tube 308, thereby reducing the working efficiency of the heating coil 108 and increasing the rotation speed of the reducing furnace tube 201. This allows the calcination and purification speed of the reducing furnace tube 201 to be controlled within a suitable range.

[0039] A power board 309 is fixedly installed at the end of the resistance tube 308 away from the pneumatic telescopic rod 306. A control line 304, an adjustment line 311, and a data line 310 are fixedly installed at the end of the power board 309 away from the resistance tube 308. An electronic air valve 303 is fixedly installed at the end of the control line 304 away from the power board 309. The electronic air valve 303 is existing technology and will not be described in detail here. The electronic air valve 303 is fixedly installed at the air inlet end of the air inlet pipe 111. The end of the adjustment line 311 away from the power board 309 is fixedly installed at the control end of the drive motor 211. A temperature control device is fixedly installed at the end of the data line 310 away from the power board 309. The temperature controller 302 is fixedly installed at the control end of the heating coil 108. Specifically, when the energized slider 307 slides on the resistance tube 308, when it slides closer to the energized plate 309, the working efficiency of the heating coil 108 decreases, the working efficiency of the drive motor 211 begins to increase, and the air intake of the electronic gas valve 303 begins to increase. When it slides away from the energized plate 309, the working efficiency of the heating coil 108 increases, the working efficiency of the drive motor 211 begins to decrease, and the air intake of the electronic gas valve 303 begins to decrease, thereby controlling the calcination temperature of the variable diameter furnace tube 201 within a suitable temperature range and avoiding large temperature fluctuations.

[0040] It should be noted that the feed inlet and discharge outlet of the reducing furnace tube 201 are sloped, which increases the residence time of the material in the reducing furnace tube 201 when it enters for calcination and purification, ensuring that the material can always remain in the calcination area.

[0041] It should be noted that the outlet of the 201 furnace tube with reduced diameter is designed to be narrowed, and the side wall discharge causes the air inlet channel and the discharge direction to deflect 90 degrees, so that they do not interfere with each other and reduce the dust of the material.

[0042] It should be noted that the spiral directions of the baffles 212 are opposite. The baffles 212 are arranged 180 degrees on the circumference, and the two baffles 212 are in perpendicular contact without gaps. The baffles 212 are firmly and tightly welded to the inner wall of the furnace tube 201 of different diameters, ensuring no sand leakage.

[0043] Working principle: When calcination of materials is required, heating coil 108 and drive motor 211 are activated. Heating coil 108 heats the reducing furnace tube 201. The material enters the reducing furnace tube 201 through the end near the exhaust pipe 213. Electronic gas valve 303 is opened. After the material falls into the reducing furnace tube 201, both the inlet and outlet of the reducing furnace tube 201 are sloped, and baffles 212 welded perpendicularly to each other are installed at an angle. The slope of the reducing furnace tube 201 and the baffles 212 block the heat-treated material in the reducing furnace tube 201 in the calcination area, ensuring that the material can always stay in the calcination area, achieving a 100% calcination physical treatment effect and improving the purification rate of quartz sand.

[0044] Meanwhile, chlorine gas is transferred to the inlet box 110 through the inlet pipe 111, and then enters the drive plate 210 from the discharge end of the reducing furnace tube 201 through the inlet pipe 109. Meanwhile, the waste gas is transferred to the outlet ring 107 through the exhaust hole 216 through the gap between the reducing furnace tube 201 and the exhaust stack 213, and then transferred to the exhaust pipe 105 through the three-way pipe 106. This allows the heat of the hot waste gas discharged from the calcining furnace to be reused, playing a role in environmental protection and energy saving.

[0045] Furthermore, when the temperature inside the reducing furnace tube 201 begins to change, the temperature of the exhaust pipe 105 discharging hot gas also begins to change. When the nitrogen in the temperature sensing coil 301 detects the temperature change, its volume begins to change. When the temperature decreases, the pneumatic telescopic rod 306 retracts, causing the energized slider 307 to slide away from the energized plate 309 on the resistance tube 308. This causes the control line 304 to control the electronic gas valve 303 to reduce the air intake of the inlet pipe 111, and the adjustment line 311 to cause the rotation speed of the drive motor 211 to decrease. Simultaneously, the data line 310 controls the temperature controller 302 to increase its output power, thus increasing the heating and calcination efficiency of the heating coil 108 on the reducing furnace tube 201. When the temperature is too high... The pneumatic telescopic rod 306 extends, causing the energized slider 307 to slide on the resistance tube 308 and approach the energized plate 309. This causes the control line 304 to control the electronic air valve 303 to increase the air intake of the air inlet pipe 111. The adjustment line 311 causes the rotation speed of the drive motor 211 to increase. At the same time, the data line 310 controls the output power of the temperature controller 302 to decrease, causing the heating efficiency of the heating coil 108 on the reducing furnace tube 201 to decrease. This controls the calcination temperature of the reducing furnace tube 201 within a suitable temperature range, avoiding large temperature fluctuations that could cause thermal stress on the inner wall surface of the reducing furnace tube 201 and accelerate the peeling of the inner lining. At the same time, it inhibits the formation of liquid chloride salts and extends the service life of the reducing furnace tube 201.
