Description

Technical Field

[0001] This invention relates to the field of quartz purification technology, and in particular to a fluorine-free and environmentally friendly quartz chemical purification device. Background Technology

[0002] With the rapid development of high-end industries such as photovoltaics, semiconductors, and fiber optic communications, the market demand for high-purity quartz sand is increasing rapidly. To meet the stringent purity requirements of these industries, chemical purification of quartz sand is typically necessary, with acid leaching (pickled quartz) being a key process for removing associated mineral impurities and gas-liquid inclusions. Traditional quartz sand pickling processes generally employ mixed acid systems containing hydrofluoric acid. Hydrofluoric acid has a strong corrosive effect on quartz surfaces, improving the wettability of the acid solution on quartz sand particles and promoting acid penetration into quartz sand deposits, thus achieving better purification results. However, hydrofluoric acid is highly toxic and corrosive, posing a serious threat to the health of operators and the environment. With increasingly stringent environmental regulations, the industry is gradually transitioning to fluorine-free environmentally friendly pickling systems, using organic acids such as oxalic acid and citric acid, or inorganic mixed acids such as sulfuric acid and hydrochloric acid, to replace hydrofluoric acid for quartz purification.

[0003] However, compared to fluorinated acid solutions, fluorine-free acid solutions lack the erosion and modification effect on the quartz surface, resulting in higher surface tension and significantly reduced wettability of quartz particles. Existing fluorine-free environmentally friendly quartz chemical purification devices often employ static acid leaching or stirred reactors, making it difficult to effectively disturb the deposited layer in the central and corner areas of the reactor bottom. This creates significant flow dead zones, leading to a significantly reduced impurity removal rate in these areas, resulting in poor overall purification uniformity, increased acid consumption, and decreased production efficiency.

[0004] In other words, the existing fluorine-free environmentally friendly quartz chemical purification device has a poor disturbance effect on the sediment layer at the bottom of the vessel. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a fluorine-free and environmentally friendly quartz chemical purification device, which has a good disturbance effect on the sediment layer at the bottom of the vessel.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A fluorine-free, environmentally friendly quartz chemical purification device, comprising:

[0008] The vessel body;

[0009] A lid, which is detachably connected to the top of the vessel body;

[0010] The inner liner is disposed within the vessel body and is rotatably connected to the vessel body. The inner liner is provided with multiple stirring plates, which are distributed at intervals along the circumference of the inner liner. The stirring plates are connected to the inner sidewall and the inner bottom wall of the inner liner and extend upward and spirally along the circumference of the inner liner.

[0011] A pressure plate is installed on the top of the vessel body and presses down on the inner liner to prevent the inner liner from moving upward relative to the vessel body;

[0012] A first motor is installed at the bottom of the vessel body, and its output end passes through the bottom wall of the vessel body and is connected to the inner liner. The first motor is used to drive the inner liner to rotate relative to the vessel body.

[0013] Furthermore, the inner liner contains a vibrating plate, which is used to vibrate the quartz sand.

[0014] Furthermore, a connecting rod is connected to the top of the vibrating plate, and a vibrator is installed on the top of the vessel lid, with the output end of the vibrator connected to the connecting rod.

[0015] Furthermore, the inner wall of the inner liner includes an inclined sidewall section, the bottom of which connects to the bottom wall of the inner liner; the stirring plate extends upward and spirally along the radial direction and circumferential direction of the inner liner.

[0016] Furthermore, the outer wall of the inclined sidewall section, the inner sidewall of the vessel body, and the bottom wall of the vessel body are provided with a heating cavity. The sidewall of the vessel body is provided with a first opening and a second opening that are respectively connected to the heating cavity. The first opening is used to allow the heating medium to enter the heating cavity, and the second opening is used to allow the heating medium to exit the heating cavity.

[0017] Furthermore, the heating medium is steam or heat-conducting oil.

[0018] Furthermore, the top of the vessel lid is provided with an air inlet and an air outlet, and the air inlet, the interior of the vessel lid, and the air outlet are connected in sequence.

[0019] Furthermore, the fluorine-free environmentally friendly quartz chemical purification device also includes a support, and the vessel body is provided with a rotating shaft that extends horizontally and is rotatably connected to the support.

[0020] Furthermore, the fluorine-free environmentally friendly quartz chemical purification device also includes a driving device, which is installed on the support and is used to drive the rotating shaft to rotate.

[0021] Furthermore, the driving device includes a second motor, a transmission chain, a driving sprocket, and a driven sprocket. The second motor is mounted on the support, the driving sprocket is connected to the output end of the second motor, the driven sprocket is sleeved on the rotating shaft, and the driving sprocket and the driven sprocket are connected by the transmission chain.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The vessel lid is detachably connected to the top of the vessel body. An inner liner is disposed within the vessel body and is rotatably connected to the vessel body. The inner liner is equipped with multiple stirring plates, which are spaced apart circumferentially along the inner liner. The stirring plates connect to the inner sidewall and bottom wall of the inner liner and extend upwards and spirally along the circumference of the inner liner. A first motor is installed at the bottom of the vessel body, its output end passing through the bottom wall of the vessel body and drivingly connected to the inner liner. The first motor drives the inner liner to rotate relative to the vessel body. When the inner liner rotates under the drive of the first motor, the lower end of the stirring plates directly scrapes the quartz sand deposit at the bottom of the inner liner, disturbing the deposited quartz sand. Under centrifugal force, the quartz sand also continuously approaches the stirring plates. The stirring plates break up the compacted quartz sand and push it upwards in a spiral direction, thereby enhancing the disturbance effect on the deposited layer at the bottom of the vessel body and improving the quartz sand purification efficiency.

[0024] 2. The pressure plate is installed on the top of the vessel body and presses down on the inner liner to prevent it from moving upwards relative to the vessel body. This ensures that the inner liner maintains a stable axial position during high-speed rotation, and that when the quartz sand is poured out after purification, the pressure plate, by abutting against the top end face of the inner liner, effectively prevents the inner liner from detaching from the vessel body, ensuring the safety and reliability of the pouring operation.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See Figures 1-3 A preferred embodiment of the present invention provides a fluorine-free environmentally friendly quartz chemical purification device, comprising: a vessel body 1, a vessel lid 2, an inner liner 3, a pressure plate 4, and a first motor 5.

[0033] The side wall of the vessel body 1 can be fitted with a jacket for introducing a heating medium (such as steam or hot water) or a cooling medium to achieve indirect temperature control of the material in the inner liner 3. The outer wall of the vessel body 1 can be fitted with an insulation layer to reduce heat loss. The vessel lid 2 is detachably connected to the top of the vessel body 1. The vessel lid 2 is used to seal the top opening of the vessel body 1 to prevent acid mist from escaping or external contaminants from entering during the reaction. The vessel lid 2 and the vessel body 1 can be connected by a flange, secured with multiple bolts and nuts, with sealing gaskets between the flange faces to ensure a tight seal. The vessel lid 2 can be equipped with a feeding port, observation window, thermometer interface, pressure gauge interface, and exhaust port 202 for easy feeding, monitoring, and exhaust gas treatment. Alternatively, as an alternative, the vessel lid 2 and the vessel body 1 can be connected by a quick-opening clamp for easy opening and closing.

[0034] The inner liner 3 can be made of corrosion-resistant material, or have an acid-resistant coating on its inner wall. The inner liner 3 is located inside the vessel body 1 and is rotatably connected to it. The inner liner 3 has a cylindrical structure, with its outer diameter smaller than the inner diameter of the vessel body 1, creating an annular gap between them. A connecting shaft can be installed at the center of the bottom of the inner liner 3, mounted to the bottom wall of the vessel body 1 via bearings, enabling a rotatable connection. The internal space of the inner liner 3 is the area for the chemical purification reaction of quartz sand and non-fluorinated acid. The inner liner 3 is equipped with multiple stirring plates 301, which are spaced apart along the circumference of the inner liner 3. The stirring plates 301 connect the inner sidewall 302 and the inner bottom wall of the inner liner 3. The stirring plates 301 extend upwards and spirally along the circumference of the inner liner 3, forming a certain helical angle with the axis of the inner liner 3. The stirring plates 301 can be integrally formed with the inner liner 3, or they can be fixed by welding or bolts. When the inner tank 3 rotates, the stirring plate 301 rotates accordingly, stirring the quartz sand and non-fluorinated acid in the inner tank 3. During the rotation, the spirally extended stirring plate 301 pushes the quartz sand and non-fluorinated acid at the bottom upwards. After the quartz sand reaches the highest point, it returns to the bottom of the inner tank 3 under the action of gravity, forming an axial circulation flow, which allows the quartz particles to fully contact the non-fluorinated acid solution and improves the purification efficiency.

[0035] The pressure plate 4 is installed on the top of the vessel body 1 and presses down on the inner liner 3 to prevent the inner liner 3 from moving upward relative to the vessel body 1. The pressure plate 4 is an annular plate-shaped component, the inner diameter of which can be less than or equal to the top inner diameter of the inner liner 3, and greater than the outer diameter of the inner liner 3. The outer diameter of the pressure plate 4 matches the top of the vessel body 1, and the pressure plate 4 is fixedly installed on the top of the vessel body 1 by bolts. The lower surface of the pressure plate 4 abuts against the top end face of the inner liner 3 or a flange provided on the inner liner 3, thereby restricting the axial movement of the inner liner 3 during rotation, and also preventing the inner liner 3 from falling out of the vessel body 1 when pouring out the purified quartz sand. It can be understood that, as an alternative setting, the pressure plate 4 can be set as a split type, composed of multiple arc-shaped pressure blocks, which is convenient for installation and disassembly.

[0036] The first motor 5 is installed at the bottom of the vessel body 1. The output end of the first motor 5 passes through the bottom wall of the vessel body 1 and is connected to the inner liner 3. The first motor 5 is used to drive the inner liner 3 to rotate relative to the vessel body 1. The output shaft of the first motor 5 can be connected to the inner liner 3 through a coupling. When the first motor 5 is started, it drives the inner liner 3 to rotate around its axis. The inner liner 3 drives the stirring plate 301 to rotate, stirring and mixing the quartz sand and non-fluorinated acid in the inner liner 3.

[0037] In use, open the vessel lid 2, pour the quartz sand to be purified and the non-fluorinated acid into the inner liner 3, then close the vessel lid 2 and start the first motor 5. The first motor 5 drives the inner liner 3 to rotate along its axis. Since the bottom of the inner liner 3 is equipped with multiple circumferentially spaced and upwardly spiraling stirring plates 301, and the lower end of the stirring plates 301 is connected to the inner bottom wall of the inner liner 3, and the side is connected to the inner side wall 302 of the inner liner 3, the stirring plates 301 rotate accordingly when the inner liner 3 rotates. The bottom of the stirring plates 301 directly scrapes and disturbs the quartz sand layer deposited at the bottom of the inner liner 3. After purification is complete, open the vessel lid 2 and pour out the purified quartz sand and non-fluorinated acid solution.

[0038] The lid 2 is detachably connected to the top of the vessel body 1. The inner liner 3 is located inside the vessel body 1 and is rotatably connected to the vessel body 1. The inner liner 3 is equipped with multiple stirring plates 301, which are distributed at intervals along the circumference of the inner liner 3. The stirring plates 301 are connected to the inner sidewall 302 and the inner bottom wall of the inner liner 3. The stirring plates 301 extend upward and spirally along the circumference of the inner liner 3. The first motor 5 is installed at the bottom of the vessel body 1, and the output end of the first motor 5 passes through the bottom wall of the vessel body 1 and is connected to the inner liner 3. The first motor 5 is used to drive the inner liner 3 to rotate relative to the vessel body 1. When the inner liner 3 rotates under the drive of the first motor 5, the lower end of the stirring plates 301 directly scrapes the quartz sand deposited at the bottom of the inner liner 3, disturbing the quartz sand deposited at the bottom of the inner liner 3. Under the action of centrifugal force, the quartz sand will also continuously move closer to the stirring plates 301. The stirring plate 301 breaks up the slab of quartz sand and pushes it upwards in a spiral direction, thereby enhancing the disturbance effect on the sediment layer at the bottom of the vessel 1 and improving the purification efficiency of the quartz sand.

[0039] The pressure plate 4 is installed on the top of the vessel body 1 and presses down on the inner liner 3 to prevent the inner liner 3 from moving upward relative to the vessel body 1. This ensures that the inner liner 3 maintains a stable axial position during high-speed rotation and ensures that when the quartz sand is poured out after purification, the pressure plate 4 effectively prevents the inner liner 3 from falling out of the vessel body 1 by abutting against the top end face of the inner liner 3, thus ensuring the safety and reliability of the pouring operation.

[0040] Preferably, the inner liner 3 contains a vibrating plate 6, which is made of corrosion-resistant material and can be disc-shaped, annular, or fan-shaped. The vibrating plate 6 is used to vibrate the quartz sand. The vibrating plate 6 is located inside the inner liner 3, at or near the bottom of the inner liner 3. The vibrating plate 6 can be made of acid-corrosion-resistant materials such as stainless steel or polyurethane. The vibrating plate 6 is in direct contact with the quartz sand, causing it to vibrate. The vibrating plate 6 can have a built-in vibration source or be connected to an external vibration source via a transmission rod. When the vibration source is activated, it transfers vibration energy to the quartz sand deposit layer at the bottom of the inner liner 3, disrupting the deposit structure and thus promoting the purification efficiency of the quartz sand. The surface of the vibrating plate 6 can be provided with raised dots or a grid pattern to enhance the dispersion effect on the quartz sand.

[0041] Preferably, a connecting rod 7 is connected to the top of the vibrating plate 6. The connecting rod 7 is a slender rod made of acid-resistant material. The lower end of the connecting rod 7 is fixedly connected to the top of the vibrating plate 6 by welding, snap-fitting, or other methods. A vibrator 8 is installed on the top of the vessel lid 2, and the output end of the vibrator 8 is connected to the connecting rod 7. A through hole is provided on the vessel lid 2 at a corresponding position for the connecting rod 7 to pass through. A sealing component, such as a mechanical seal or a rubber sealing ring, is installed in the through hole to prevent acid mist from escaping during the reaction process. The vibrator 8 can be a pneumatic vibrator 8, an electromagnetic vibrator 8, or an ultrasonic vibrator 8. The output end of the vibrator 8 is fixedly connected to the upper end of the connecting rod 7. When the vibrator 8 is started, its output vibration is transmitted to the vibrating plate 6 through the connecting rod 7, causing the vibrating plate 6 to generate high-frequency vibration. The vibrator 8 can also be connected to a controller to adjust the vibration frequency and amplitude to adapt to the dispersion requirements of quartz sand with different particle sizes.

[0042] Preferably, the inner wall 302 of the inner liner 3 includes an inclined sidewall section 3021, the bottom of which connects to the bottom wall of the inner liner 3; the stirring plate 301 extends upward and radially outward and circumferentially spirally along the inner liner 3. The stirring plate 301 is disposed on the inclined sidewall, which extends upward and outward from the edge of the bottom wall of the inner liner 3, connecting the bottom wall of the inner liner 3 and the straight cylindrical sidewall of the inner liner 3, forming a conical or trumpet-shaped transition zone. The angle between the inclined sidewall and the bottom wall can be an obtuse angle, so that the quartz sand can converge towards the center under gravity, and also facilitates the scraping and pushing of the sediment layer by the stirring plate 301. Multiple stirring plates 301 are disposed on the inclined sidewall, that is, the lower end of the stirring plate 301 connects to the edge of the bottom wall of the inner liner 3 or the lower edge of the inclined sidewall, and the side edge is attached to the surface of the inclined sidewall and extends upward spirally. When the inner liner 3 rotates, the quartz sand deposited at the bottom can be transported upward along the inclined side wall, which promotes the purification efficiency of the quartz sand.

[0043] Preferably, a heating chamber is formed by the outer wall of the inclined sidewall section 3021, the inner wall of the vessel body 1, and the bottom wall of the vessel body 1. The sidewall of the vessel body 1 has a first opening 101 and a second opening 102 respectively communicating with the heating chamber. The first opening 101 allows the heating medium to enter the heating chamber, and the second opening 102 allows the heating medium to exit the heating chamber. The first opening 101 and the second opening 102 can be fitted with threaded pipe joints or flanges for connection to an external heating system. The inclined sidewall of the inner liner 3, together with the sidewall and bottom wall of the vessel body 1, forms a cavity that serves as the heating chamber. The heating medium enters through the first opening 101, flows through the heating chamber, and heats the inclined sidewall of the inner liner 3, thereby indirectly heating the non-fluorinated acid and quartz sand in the inner liner 3, increasing the reaction rate of the chemical purification. The heated medium, after heat exchange, exits through the second opening 102 and can be recycled or recovered.

[0044] Preferably, the heating medium is steam or heat-conducting oil. The first opening 101 and the second opening 102 are respectively connected to an external heating pipeline, which can selectively supply steam or heat-conducting oil as the heating medium. Depending on the process temperature required for the chemical purification of quartz sand, the operator can selectively introduce a suitable heating medium into the heating chamber to achieve precise temperature control. It is understood that, as an alternative, hot water can also be used as the heating medium.

[0045] Preferably, the top of the vessel lid 2 is provided with an air inlet 201 and an exhaust outlet 202, and the air inlet 201, the interior of the vessel lid 2, and the exhaust outlet 202 are sequentially connected. The air inlet 201 and exhaust outlet 202 are respectively located on the top of the vessel lid 2, penetrate the vessel lid 2, and communicate with the interior of the vessel body 1. The air inlet 201 is used to introduce a protective gas (such as nitrogen or argon) or a reactive gas (such as chlorine) into the vessel body 1 to adjust the reaction atmosphere or assist the purification process. The air inlet 201 can be connected to a gas pipeline and equipped with valves and flow meters to control the gas flow rate. The exhaust outlet 202 is used to discharge waste gases (such as acid mist or reaction byproduct gases) generated inside the vessel body 1, and can be connected to a tail gas treatment device to prevent harmful gases from being emitted into the environment. Both the air inlet 201 and the exhaust outlet 202 can be equipped with quick-connect couplings or flange interfaces for easy pipeline connection.

[0046] Preferably, the fluorine-free environmentally friendly quartz chemical purification device further includes a support 9. The vessel body 1 is provided with a rotating shaft 103, which extends horizontally and is rotatably connected to the support 9. The support 9, serving as the foundation for the entire device, can be made of welded steel or cast iron, and has anchor bolt holes at its bottom for fixing to the ground or operating platform. The support 9 has two supporting arms, located on opposite sides of the vessel body 1. Rotating shafts 103 are fixedly installed on both sides of the outer wall of the vessel body 1, coaxially arranged and extending horizontally, with the axis of the rotating shafts 103 perpendicular to the axis of the vessel body 1. The rotating shafts 103 are mounted on the supporting arms of the support 9 via bearing seats, allowing the vessel body 1 to rotate or tilt relative to the support 9 around its horizontal axis. When it is necessary to pour out the purified quartz sand from the inner liner 3, the operator can manually or electrically drive the rotating shaft 103 to rotate, causing the vessel body 1 to tilt at a certain angle around the rotating shaft 103, so that the opening of the inner liner 3 faces downward or to the side downward, facilitating the smooth pouring out of the quartz sand. A handwheel, crank, or geared motor can be installed at one end of the rotating shaft 103 to control the tilt angle. A locking mechanism can be installed between the rotating shaft 103 and the bearing seat to lock the position after tilting to the desired angle, preventing accidental return to its original position.

[0047] Preferably, the fluorine-free environmentally friendly quartz chemical purification device further includes a drive unit 10, which is mounted on the support 9 and is used to drive the rotating shaft 103 to rotate. The drive unit 10 can be manually driven or electrically driven. Manual drive includes a handwheel or crank, which is directly fixedly connected to one end of the rotating shaft 103. The operator tilts the vessel body 1 around the rotating shaft 103 by rotating the handwheel or crank. Electric drive includes a geared motor, stepper motor, or servo motor, whose base is fixed to the support arm of the support 9 by bolts. The motor's output shaft is connected to the rotating shaft 103 via a coupling or transmission belt. When the motor starts, it drives the rotating shaft 103 to rotate, achieving electric tilting of the vessel body 1. The drive unit 10 can be equipped with a worm gear reducer, which utilizes the self-locking characteristic of the worm gear to automatically lock when stopped at any tilt angle, preventing the vessel body 1 from rotating back on its own.

[0048] Preferably, the drive device 10 includes a second motor 1001, a transmission chain 1002, a drive sprocket 1003, and a driven sprocket 1004. The second motor 1001 is mounted on the support 9. The drive sprocket 1003 is connected to the output end of the second motor 1001. The driven sprocket 1004 is sleeved on the rotating shaft 103. The drive sprocket 1003 and the driven sprocket 1004 are connected by the transmission chain 1002. The second motor 1001 can be a geared motor or a regular motor with a reducer. Its base is fixed to the side wall or support arm of the support 9 by bolts. The drive sprocket 1003 is fixedly mounted on the output shaft of the second motor 1001 and is connected to the output shaft by a key or set screw. The driven sprocket 1004 is sleeved on the rotating shaft 103 on the side of the vessel body 1 and is also fixed by a key or expansion sleeve. The drive chain 1002 is a sleeve roller chain that wraps around the outer circumference of the driving sprocket 1003 and the driven sprocket 1004, forming a closed transmission circuit. When the second motor 1001 starts, the driving sprocket 1003 rotates, driving the driven sprocket 1004 and the rotating shaft 103 to rotate synchronously via the drive chain 1002, thereby tilting the vessel body 1 around the horizontal axis. Chain drives have advantages such as accurate transmission ratio, high load capacity, and adaptability to harsh environments, and are especially suitable for high torque, low-speed tilting applications. The tooth ratio of the driving sprocket 1003 to the driven sprocket 1004 can be designed according to the required tilting speed and torque. Typically, the driven sprocket 1004 has more teeth than the driving sprocket 1003 to achieve speed reduction and torque increase. A protective cover can be installed on the outside of the drive chain 1002 to prevent dust intrusion and injury to operators.
