Description

Technical Field

[0001] This invention relates to the field of quartz sand purification equipment technology, specifically to a purification device for refining ultra-white quartz sand. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is milky white or colorless and translucent. It is an important industrial mineral raw material, a non-hazardous chemical, and is widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media, and other industries. To obtain high-quality quartz sand, it needs to be purified, thus requiring a purification device.

[0003] In the prior art, such as Chinese patent application CN118022937A, a quartz sand purification device for semiconductor quartz sand manufacturing belongs to the semiconductor manufacturing field. It includes a conveying device with support frames fixedly installed on both sides of the top of the conveying device. A screening barrel is fixedly connected to the top of the four support frames. A grinding barrel is installed on top of the screening barrel, with its bottom extending into the interior of the screening barrel. A grinding component is fixedly installed on top of the grinding barrel, with its bottom extending through the grinding barrel into the interior of the screening barrel. A connecting port is provided on one side of the screening barrel. By setting a screening barrel and a grinding barrel on top of the conveying device, the grinding component grinds the quartz sand inside the grinding barrel. The ground quartz sand can then be screened again inside the screen frame, separating quartz sand of suitable particle size and retaining large particles. This avoids excessively large quartz sand particles that, due to insufficient soaking time in the pickling tank, would result in inadequate pickling, affecting subsequent semiconductor manufacturing.

[0004] In the aforementioned patent, although the device can perform multi-stage filtration and screening of quartz sand, the quartz sand will agglomerate after screening, which will affect the screening effect of the quartz sand. Furthermore, the agglomerated quartz sand will clog the screen. In order not to affect the normal use of the screening machine, the screen needs to be cleaned regularly, which will greatly reduce the screening efficiency of quartz sand and cannot remove the mechanical iron in the quartz sand. Therefore, a new quartz sand removal device is needed. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, by setting up a grinding mechanism, a primary screening mechanism, a secondary screening mechanism, and a conveying mechanism in combination, the crushing and screening of quartz can be achieved. Quartz sand is pressurized and ground by the grinding components. The ground quartz sand enters the primary screening mechanism for preliminary screening. The screened quartz sand then enters the secondary screening mechanism, where it undergoes multi-stage purification under the action of a nano-separation mesh. In conjunction with an ultrasonic separation component, the quartz sand in the secondary screening structure is crushed and agglomerates in the quartz sand are dispersed. At the same time, impurities and contaminants on the surface of the quartz sand are removed, thus preventing agglomerates from clogging the nano-separation mesh. The ultrasonic separation component can also vibrate the nano-separation mesh to remove impurities, eliminating the need for regular cleaning of the nano-separation mesh and improving the purification efficiency of the quartz sand. Then, with the help of a centrifugal structure, the separated waste sand residue is removed and collected, and the mechanical iron in the quartz sand can be removed by a magnetic separation component.

[0021] 2. In this invention, the quartz sand can be preliminarily purified by setting up a primary screening mechanism. With the cooperation of optical sensors and cleaning components, the screen can be intelligently cleaned to prevent impurities from clogging the screen. This eliminates the need for manual cleaning of the screen, which not only improves the efficiency of the primary screening mechanism but also reduces the cost of manual cleaning.

[0022] 3. In this invention, during the overall purification process, the magnetic substances present in the fine quartz sand produced after grinding are adsorbed and separated by the combined use of the iron removal component and the magnetic separation component. Then, the magnetic adjustment structure is used simultaneously to adsorb the magnetic impurities inside the quartz sand by converting between strong and weak magnetic fields, thereby improving the purification effect.

[0035] 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. Example 1

[0036] Reference Figures 1-11The apparatus for purifying refined ultra-white quartz sand includes a grinding mechanism 1 for abrasives and a conveying mechanism 4 for conveying. The grinding mechanism 1 has a primary screening mechanism 2 and a secondary screening mechanism 3 respectively installed on one side of its outer wall. Each secondary screening mechanism 3 includes a metal frame 30, an ultrasonic separation component 34, and a magnetic separation component 35. A filter box 31 is fixedly installed on the top of the metal frame 30, and the two ends of the outer wall of the filter box 31 are respectively connected to a feed end 36 and a waste end 37. A discharge end 32 is provided at the bottom of the filter box 31. A door 33 is provided on one side of the outer wall of the filter box 31. A rotating roller 38 is movably inserted into the inner surface of the feed end 36, and a spiral plate 39 and a centrifugal plate 310 are fixedly installed on the outer surface of the rotating roller 38. A fifth motor 311 is fixedly installed on the other side of the outer wall of the metal frame 30, and the fifth motor 311 is connected to the rotating roller 38 via a second belt 312. Next, a nano-separation mesh 313 is fixedly installed on the inner wall of the filter box 31. The ultrasonic separation component 34 and the magnetic separation component 35 are respectively fixedly installed on one side and the bottom side of the outer wall of the metal frame 30. The ultrasonic separation component 34 includes an ultrasonic generator 340 and a set of ultrasonic transducers 341. The ultrasonic generator 340 and the ultrasonic transducers 341 are electrically connected. The set of ultrasonic transducers 341 all pass through the door 33 and are attached to the outer wall of the nano-separation mesh 313. A connecting plate 342 is fixedly installed on one side of the outer wall of the door 33. The connecting plate 342 is fixedly sleeved between the outer walls of the set of ultrasonic transducers 341. The magnetic separation component 35 includes a fixing ring 350. The fixing ring 350 is fixed to the bottom of the metal frame 30. An insulating cylinder 351 is fixedly installed on the inner wall of the fixing ring 350. A magnetic coil 352 is set inside the insulating cylinder 351. A magnetic mesh 353 is set in the inner ring of the insulating cylinder 351.

[0037] The overall effect of Embodiment 1 is as follows: Starting the fifth motor 311, under the transmission connection of the second belt 312, will drive the rotating roller 38 to rotate. When the rotating roller 38 rotates, it will drive the spiral plate 39 and the centrifugal plate 310 to rotate. The spiral plate 39, while rotating, will transport the quartz sand into the filter box 31. Under the action of the nano-separation mesh 313, the quartz sand can be purified in multiple stages. The purified quartz sand will be discharged through the discharge end 32, and the waste will be discharged through the waste end 37. During the rotation of the centrifugal plate 310, it will lift the quartz sand, causing it to be centrifugally thrown out and impacting the nano-separation mesh 313 with equal pore sizes. The fine quartz sand... The process accelerates the flow through the nano-separation mesh 313. At this time, the ultrasonic generator 340 is activated to send ultrasonic waves. The ultrasonic waves are converted into mechanical vibrations by the ultrasonic transducer 341, which causes the nano-separation mesh 313 to vibrate. This not only removes impurities from the surface of the nano-separation mesh 313, but also breaks up agglomerated quartz sand, thus preventing the agglomerated quartz sand from clogging the nano-separation mesh 313. The sieved quartz sand falls onto the magnetic mesh 353 at the bottom. At this time, the magnetic coil 352 is energized, which generates a magnetic field inside the insulating cylinder 351. The mechanical iron inside the quartz sand is then attracted to the magnetic mesh 353, thus completing the removal of mechanical iron. Example 2

[0038] according to Figure 5 , Figure 6 and Figure 11As shown, a water tank 354 is fixedly installed on one side of the outer wall of the metal frame 30, and a pump 355 is fixedly connected to the top of the water tank 354. A nozzle 356 is fixedly connected to the output end of the pump 355, and the nozzle 356 is located on top of the magnetic mesh 353. The primary screening mechanism 2 includes a set of first legs 20, a cleaning assembly 23, and an iron removal assembly 24. A set of springs 21 is provided on the top of each first leg 20, and a screening box 22 is fixedly installed on the top of each spring 21. A transmission rod 25 is movably inserted into the inner wall of the screening box 22, and an eccentric wheel 26 is fixedly sleeved on one end of the outer wall of the transmission rod 25. A screen 27 is installed inside the screening box 22. A second support leg 28 is fixedly installed on one side of the outer wall of the screening box 22, and a fourth motor 29 is fixedly installed on the top of the second support leg 28. A first belt 210 is connected between the fourth motor 29 and the transmission rod 25. A transmission assembly 211 is installed at the bottom of the screening box 22, and a cleaning assembly 23 is located at the top of the screening box 22. The iron removal assembly 24 is located on top of the conveying assembly 211. A waste box 212 is provided at the bottom of the screening box 22. The cleaning assembly 23 includes a slide rail 230, which is fixedly installed on the top of the screening box 22. A threaded rod 231 is movably inserted into the inner wall of the slide rail 230, and a slider 233 is movably sleeved on the outer wall of the threaded rod 231. A second motor 232 is fixedly installed on one side of the outer wall of the slide rail 230, and the output end of the second motor 232 is fixed to one end of the outer wall of the threaded rod 231. The top of the slider 233 is fixedly fitted with two electric push rods 234, and the bottom of the two electric push rods 234 is fixedly installed with a sweeping disc 235. The top and inside of the screening box 22 are respectively fixedly installed with a PLC controller 236 and a set of optical sensors 237, and each optical sensor 237 is connected to the PLC controller 236 by signal. The PLC controller 236 is electrically connected to the second motor 232 and the electric push rods 234, and is also connected to the sweeping disc 235 by signal.

[0039] The overall effect of Embodiment 2 is as follows: Starting the pump 355 draws cleaning water from the water tank 354, which is then sprayed out through the nozzle 356. The sprayed cleaning water cleans the mechanical iron adhering to the surface of the magnetic mesh 353. Starting the fourth motor 29, under the transmission connection of the first belt 210, drives the transmission rod 25 to rotate, which in turn drives the eccentric wheel 26 to rotate. The eccentric wheel 26 generates eccentric force during rotation, which, with the cooperation of the spring 21, causes the screening box 22 to vibrate. When the screening box 22 vibrates, it causes the screen 27 to vibrate, thus screening the quartz sand on the surface of the screen 27. The screened quartz sand falls onto the bottom conveyor assembly 211. After screening is complete... The optical sensor 237 is a diffuse reflection sensor that senses the holes on the surface of the screen 27. When the holes in the screen 27 are blocked, the optical sensor 237 transmits the detected data to the PLC controller 236. The PLC controller 236 then controls the second motor 232 to rotate the threaded rod 231. When the threaded rod 231 rotates, it drives the slider 233 to move laterally, which in turn moves the bottom cleaning disc 235 on the surface of the screen 27. Activating the electric push rod 234 presses the cleaning disc 235 onto the surface of the screen 27. As the cleaning disc 235 moves on the surface of the screen 27, it cleans the screen 27. Combined with the sensing of the optical sensor 237, intelligent cleaning can be achieved. Example 3

A third belt 46 is connected between the sixth motor 45 and the transmission roller 44. A fourth belt 47 is connected between the transmission roller 44 and one of the cylinders 41. An iron frame 48 is fixedly installed at the top of the bottom frame 40. A material blocking box 49 is fixedly installed on the inner wall of the iron frame 48. The conveying mechanism 4 is respectively set between the grinding mechanism 1 and the primary screening mechanism 2 and between the primary screening mechanism 2 and the secondary screening mechanism 3.

[0041] The overall effect achieved in Embodiment 3 is as follows: Starting the third motor 244, under the transmission connection of the chain 245, drives the guide roller 242 to rotate, which in turn drives the magnetic separator belt 243 to rotate. When the quartz sand passes the bottom of the magnetic separator belt 243, under the action of the permanent magnet 246, the mechanical iron inside the quartz sand is attracted out. Then, under the transmission action of the magnetic separator belt 243, the mechanical iron is thrown out and collected in the scrap iron box 247, thus completing the iron removal effect of the quartz sand. Starting the first motor 16, under the meshing action of the reduction gear 17 and the driven gear 12, drives the grinding cylinder 11 to rotate, which in turn synchronously drives the spiral rod 15. The cylinder rotates, and at this time, the quartz sand enters the grinding cylinder 11 through the feed cylinder 13. Steel balls or steel plates are added to the grinding cylinder 11. When the grinding cylinder 11 rotates, it will swing the steel balls or steel bars up. Under the action of gravity, the steel balls or steel bars will fall down, thereby crushing the quartz sand. The crushed quartz sand will be discharged through the discharge cylinder 14 and fall into the bottom blocking box 49. The sixth motor 45 is started. Under the transmission connection of the third belt 46, it will drive the transmission roller 44 to rotate. Then, under the transmission connection of the fourth belt 47, it will drive the cylinder 41 to rotate, which will drive the conveyor belt 42 to rotate, thereby conveying the quartz sand forward.

[0042] The operating method and working principle of this device are as follows: First, a loader pours quartz sand into the feed box 18, which then falls into the feed cylinder 13. At this time, the first motor 16 is started. Under the meshing action of the reduction gear 17 and the driven gear 12, the grinding cylinder 11 is driven to rotate, which in turn drives the screw rod 15 to rotate synchronously. At this time, the quartz sand enters the grinding cylinder 11 under the action of the screw rod 15. Steel balls or steel plates are added to the grinding cylinder 11. When the grinding cylinder 11 rotates, it will swing the steel balls or steel rods up. Under the action of gravity, the steel balls or steel rods will fall down, thereby crushing the quartz sand. The crushed quartz sand will be discharged through the discharge cylinder 14 and will fall into the bottom retaining box 49. Then, the sixth motor 45 is started. Under the transmission of the third belt 46, the transmission roller 44 rotates. Then, under the transmission of the fourth belt 47, the cylinder 41 rotates, which in turn drives the conveyor belt 42 to rotate, thus conveying the quartz sand forward. The quartz sand then falls into the screening box 22. The fourth motor 29 is started, and under the transmission of the first belt 210, the transmission rod 25 rotates, which in turn drives the eccentric wheel 26 to rotate. The eccentric wheel 26 generates eccentric force during rotation, which, with the cooperation of the spring 21, causes the screening box 22 to vibrate. When the screening box 22 vibrates, it drives the screen 27 to vibrate, thus screening the quartz sand on the surface of the screen 27. The screened quartz sand... Quartz sand falls onto the bottom conveyor assembly 211. The third motor 244 is started, and under the transmission connection of the chain 245, it drives the guide roller 242 to rotate, which in turn drives the magnetic separator belt 243 to rotate. When the quartz sand passes the bottom of the magnetic separator belt 243, the permanent magnet 246 attracts the mechanical iron inside the quartz sand. Then, under the transmission action of the magnetic separator belt 243, the mechanical iron is thrown out and collected in the scrap iron box 247, thus completing the iron removal effect of the quartz sand. The screened quartz sand falls into the feed end 36 through the conveyor mechanism 4. The fifth motor 311 is started, and under the transmission connection of the second belt 312, it drives the rotating roller 38 to rotate. When the rotating roller 38 rotates... When in operation, the spiral plate 39 and centrifugal plate 310 rotate. The spiral plate 39, while rotating, conveys the quartz sand into the filter box 31. Under the action of the nano-separation mesh 313, the quartz sand undergoes multi-stage purification. The purified quartz sand is discharged through the discharge end 32, and the waste is discharged through the waste end 37. During rotation, the centrifugal plate 310 scoops up the quartz sand, causing it to be centrifugally ejected and impact the nano-separation mesh 313 with equal pore sizes. The finer quartz sand passes through the nano-separation mesh 313 at an accelerated speed. At this time, the ultrasonic generator 340 is activated, sending ultrasonic waves. The ultrasonic waves are converted into mechanical vibrations by the ultrasonic transducer 341, causing the nano-separation mesh 313 to vibrate.Not only can it remove impurities from the surface of the nano-separation mesh 313, but it can also break up agglomerated quartz sand, thus preventing the agglomerated quartz sand from clogging the nano-separation mesh 313. The sieved quartz sand will fall onto the magnetic mesh 353 at the bottom. At this time, the magnetic coil 352 is energized, which will generate a magnetic field inside the insulating cylinder 351. At this time, the mechanical iron inside the quartz sand will be attracted to the magnetic mesh 353, thus completing the removal of mechanical iron. After screening is completed, the optical sensor 237 is a diffuse reflection sensor that senses the holes on the surface of the screen 27. When the holes of the screen 27 are blocked, the optical sensor 237 will transmit the detected data to the PLC controller 236, and the PLC controller 236 will control the... The second motor 232 drives the threaded rod 231 to rotate. When the threaded rod 231 rotates, it drives the slider 233 to move laterally, which in turn moves the bottom cleaning disc 235 on the surface of the screen 27. Activating the electric push rod 234 presses the cleaning disc 235 onto the surface of the screen 27. As the cleaning disc 235 moves on the surface of the screen 27, it cleans the screen 27. Combined with the sensing of the optical sensor 237, intelligent cleaning is achieved. Activating the pump 355 draws cleaning water from the water tank 354, which is then sprayed out through the nozzle 356. The sprayed cleaning water cleans the mechanical iron adhering to the surface of the magnetic mesh 353. In summary, this solves the problems mentioned in the background.
