Description

Technical Field

[0001] This invention relates to the field of high-purity quartz sand processing technology, and in particular to a method and apparatus for removing gas-liquid inclusions from high-purity quartz sand by oil immersion treatment. Background Technology

[0002] Oil immersion treatment equipment is a device specifically designed to remove gas-liquid inclusions from high-purity quartz sand. Its main principle is to use a specific oil immersion liquid and control the temperature, pressure and immersion time to promote the removal of gas or liquid inclusions on the surface of quartz sand particles, thereby improving the purity and quality of quartz sand.

[0003] When quartz sand particles of a certain size fall onto the conveyor belt through the hopper, the quartz sand particles tend to accumulate. This can lead to uneven spraying when solvent oil is applied later, preventing some of the stacked quartz sand from fully contacting the solvent oil. As a result, during the oil immersion process, these particles that have not made sufficient contact with the solvent oil may not be able to effectively remove gas-liquid inclusions, thus affecting the purity of the quartz sand and the treatment effect, and reducing the quality of the final product. Summary of the Invention

[0004] The technical problem this invention aims to solve is that when quartz sand particles of a certain size fall onto the conveyor belt through a hopper, the quartz sand particles tend to accumulate, leading to uneven spraying of solvent oil during subsequent application. This results in some of the stacked quartz sand particles failing to fully contact the solvent oil, making it difficult for these particles to effectively remove gas-liquid inclusions during the oil immersion process. Consequently, the purity of the quartz sand and the treatment effect are affected, reducing the quality of the final product.

[0005] The technical solution adopted by this invention to solve its technical problem is: a method and apparatus for removing gas-liquid inclusions from high-purity quartz sand by oil immersion treatment, comprising a base, with circular shafts symmetrically installed through the inner wall of the base, a conveyor belt sleeved on the outer surface of the circular shafts, a feed hopper fixedly installed on one side of the base, a nozzle frame fixedly installed on one side of the base, a storage tank provided on one side of the base, an oil pump provided on the top of the storage tank, wherein the inlet pipe of the oil pump is inserted through the inner wall of the storage tank, one side of the outlet of the oil pump is fixedly connected to one side of the nozzle frame, a control box provided on one side of the base, and several robotic arms provided on one side of the base. A bracket is fixedly installed on one side of the base, and several cameras are installed on one side of the bracket. A cleaning brush is rotatably installed on one side of the base, and a collection box is installed on one side of the base. A sludge pump is installed on one side of the collection box, and a conveying pipe is fixedly installed at the outlet of the sludge pump. One end of the conveying pipe passes through one side of the base and is located above the feeding hopper. A leveling device is installed on the inner wall of the base between the feeding hopper and the spray pipe frame. The leveling device can use a motor-driven round rod and a striking rod to intermittently strike and vibrate the conveyor belt, so that the quartz sand conveyed on the conveyor belt is not easy to accumulate. At the same time, the leveling scraper scrapes it to make it flat, so as to facilitate full contact with solvent oil later.

[0006] The aforementioned components achieve the following effect: Quartz sand particles of a certain size are placed into the feeding hopper and then fall onto the conveyor belt. At this point, the drive motor on the base is activated, rotating the shaft and thus the conveyor belt transports the quartz sand particles. Once the particles reach a certain position, a leveling device vibrates and levels the stacked quartz sand particles, spreading them evenly on the conveyor belt. The conveying continues. When passing under the spray nozzle frame, an oil pump is activated to draw solvent oil from the storage tank into the spray nozzle frame, spraying the solvent oil evenly onto the sand surface. This ensures the quartz sand is fully wetted by the solvent oil. Because the refractive index of this solvent oil is essentially the same as that of natural quartz, the quartz sand particles, which contain no or only a small amount of gas-liquid inclusions, become transparent after being wetted by the solvent oil. In this process, quartz sand particles containing a high amount of gas-liquid inclusions appear milky white and opaque after being soaked in solvent oil. When the solvent-oil-sprayed quartz sand is transported to the lower end of the camera, the camera identifies the different colors of quartz sand and transmits signals to the control box. The control box then directs a robotic arm to pick out the milky white and opaque quartz sand particles, while the more transparent particles continue to be conveyed. Once a certain position is reached, the drive motor on the base is activated, rotating the cleaning brush to sweep the particles into a collection box for degreasing and purification. This yields high-purity quartz sand with a lower content of gas-liquid inclusions. To improve the removal and processing effect and purity, a mud pump is typically used to pump the quartz sand particles that have fallen into the collection box back into the conveying pipe, and then they fall back into the feed hopper for secondary removal processing.

[0007] Preferably, the leveling device includes a round rod, with both ends of the round rod respectively penetrating and installed on both sides of the inner wall of the base; a plurality of striking rods, with one side of the striking rods fixedly installed on the outer surface of the round rod; a driving mechanism, wherein the driving mechanism is disposed between one side of the round rod and the inner wall of the base, for driving the round rod and the plurality of striking rods to perform intermittent striking and vibration treatment on the conveyor belt; and an auxiliary mechanism, wherein the auxiliary mechanism is disposed on one side of the base above the conveyor belt, for leveling the conveyed quartz sand particles.

[0008] The effects achieved by the above components are as follows: By setting up a leveling device, the auxiliary mechanism is first adjusted to a certain height, and then quartz sand particles of a certain size are put into the feeding hopper. The particles then fall onto the conveyor belt through the feeding hopper. At this time, the drive motor on the base is started to drive the round shaft to rotate, which in turn drives the conveyor belt to convey the quartz sand particles. When the particles are conveyed to a certain position, the drive mechanism can be started to drive the round rod and several striking rods to knock and vibrate the conveyor belt at intervals, causing the quartz sand conveyed on the conveyor belt to vibrate and disperse, making it less likely to accumulate. At the same time, with the help of the auxiliary mechanism, the particles are scraped off and leveled, which facilitates full contact with the solvent oil in the later stage, effectively removing gas-liquid inclusions, improving the purity of the quartz sand, the processing effect, and the quality of the final product.

[0009] Preferably, reinforcing rods are fixedly installed on both sides of one end of the striking rod, and one side of the reinforcing rod is fixedly installed on the outer surface of the round rod.

[0010] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the striking rod and the round rod can be increased, making the connection more solid and stable, and less prone to breakage and damage.

[0011] Preferably, a protective block is fixedly installed on the outer surface of one end of the striking rod, and the protective block is made of rubber.

[0012] The effect achieved by the above components is that by setting up protective blocks, the impact wear between one end of the striking rod and the conveyor belt can be reduced, thus preventing damage to the conveyor belt.

[0013] Preferably, the driving mechanism includes a spur gear, the inner wall of which is fixedly mounted on the outer surface of one end of a round rod; a torsion spring, wherein the inner wall of the torsion spring is sleeved on the outer surface of one end of the round rod, and both ends are fixedly mounted on one side of the spur gear and one side of the base, respectively; and a servo motor, wherein one side of the servo motor is fixedly mounted on one side of the base, and a sector gear is fixedly mounted on the output end of the servo motor via a coupling, wherein the outer surface of the sector gear meshes with the outer surface of the spur gear.

[0014] The effect achieved by the above components is as follows: when removing gas-liquid inclusions from high-purity quartz sand particles through the drive mechanism, the servo motor can be started to drive the sector gear to rotate, which in turn can drive the circular gear to rotate intermittently. Then, in conjunction with the deformation and reset of the torsion spring, the circular rod and several striking rods can be driven to rotate left and right intermittently, thereby performing intermittent striking on the inner wall of the conveyor belt, vibrating and spreading the quartz sand particles conveyed on its surface, avoiding accumulation and affecting the removal processing effect.

[0015] Preferably, a protective cover is fixedly installed on one side of the base, and the servo motor, spur gear, torsion spring and sector gear are all disposed in the inner wall of the protective cover.

[0016] The effect achieved by the above components is that by setting up a protective cover, impurities in the air can be effectively prevented from falling between the spur gear and the sector gear, thus preventing jamming and affecting rotation.

[0017] Preferably, the auxiliary mechanism includes a screw hole frame, both sides of which are fixedly mounted on one side of the base; a threaded rod, one end of which is helically inserted into the inner wall of the screw hole frame; and a leveling scraper, one side of which is rotatably mounted on one side of the threaded rod.

[0018] The effect achieved by the above-mentioned components is as follows: By setting up an auxiliary mechanism, after the quartz sand particles fall onto the conveyor belt in the main feed hopper, the threaded rod can be turned to a certain angle on the screw hole frame according to actual usage requirements, so that the height of one side of the scraper frame from the top of the conveyor belt is leveled, which is consistent with the passage of a thin layer of quartz sand particles. This can effectively prevent the accumulation of conveyed quartz sand particles, so that the subsequent solvent oil can fully contact the conveyed quartz sand particles, effectively remove gas-liquid inclusions, improve the purity of quartz sand, the processing effect and the quality of the final product.

[0019] Preferably, a bearing is fixedly installed at one end of the threaded rod, and the outer ring of the bearing is fixedly installed on one side of the leveling scraper.

[0020] The effect achieved by the above components is that by setting bearings, the rotational wear between the threaded rod and the leveling scraper can be reduced, thereby increasing the service life of both.

[0021] Preferably, a method for removing gas-liquid inclusions from high-purity quartz sand by oil immersion treatment, using the aforementioned apparatus for removing gas-liquid inclusions from high-purity quartz sand by oil immersion treatment, includes the following steps:

[0022] S1. First, according to the particle size of the quartz sand to be processed, turn the threaded rod on the screw hole frame in the auxiliary mechanism, adjust the distance between the leveling scraper and the top of the conveyor belt through the bearing to ensure that only a thin layer of quartz sand is allowed to pass through. At the same time, check the solvent oil storage in the storage tank, confirm that the oil pump, servo motor, camera, robotic arm and other components are connected normally, and start the control box to initialize the equipment parameters.

[0023] S2. Place high-purity quartz sand particles of a certain size into the feed hopper, start the drive motor on the base to drive the round shaft to rotate, so that the conveyor belt can run. The quartz sand falls evenly onto the conveyor belt through the feed hopper and is conveyed towards the nozzle frame with the conveyor belt.

[0024] S3. Start the drive mechanism of the leveling device. The servo motor drives the sector gear to rotate, intermittently meshing with the round gear and cooperating with the deformation and reset of the torsion spring. The drive rod and the striking rod intermittently strike the conveyor belt, causing the accumulated quartz sand to vibrate and disperse. At the same time, the leveling scraper scrapes the quartz sand on the conveyor belt to flatten it and prevent it from accumulating.

[0025] S4. When the leveled quartz sand is transported to the bottom of the spray gun frame, start the oil pump to extract the solvent oil from the storage tank and transport it to the spray gun frame. Spray the solvent oil evenly onto the surface of the quartz sand through the spray gun frame to fully wet the quartz sand.

[0026] S5. The soaked quartz sand continues to be conveyed to the area below the camera. The camera identifies the color of the quartz sand and transmits the signal to the control box. The control box instructs the robotic arm to pick out and remove the milky white and opaque quartz sand particles, leaving the transparent particles.

[0027] S6. When qualified quartz sand is delivered to the end, start the drive motor to drive the cleaning brush to rotate and sweep the quartz sand into the collection box. Start the mud pump to pump the quartz sand in the collection box back to the feed hopper through the conveying pipe for secondary oil immersion treatment to improve purity.

[0028] S7. After multiple treatments, the quartz sand in the collection box is de-oiled to remove residual solvent oil from the surface, and then purified to finally obtain high-purity quartz sand with very low content of gas-liquid inclusions.

[0029] The beneficial effects of this invention are:

[0030] By setting up a leveling device, the conveyor belt can be vibrated intermittently by a motor-driven round rod and a striking rod, which prevents the quartz sand conveyed on the conveyor belt from accumulating. At the same time, the leveling scraper scrapes it off and flattens it, which facilitates full contact with solvent oil in the later stage, effectively removes gas-liquid inclusions, improves the purity of quartz sand, the processing effect and the quality of the final product.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Figure 1-5The method and apparatus for removing gas-liquid inclusions from high-purity quartz sand by oil immersion treatment are shown. The apparatus includes a base 1, with circular shafts 3 symmetrically installed through the inner wall of the base 1. A conveyor belt 4 is fitted onto the outer surface of the circular shafts 3. A feed hopper is fixedly installed on one side of the base 1, a nozzle frame 6 is fixedly installed on one side of the base 1, a storage tank 7 is located on one side of the base 1, and an oil pump 8 is installed on the top of the storage tank 7. The inlet pipe of the oil pump 8 is inserted through the inner wall of the storage tank 7, and one side of the outlet of the oil pump 8 is fixedly connected to one side of the nozzle frame 6. A control box 9 is located on one side of the base 1, several robotic arms 10 are located on one side of the base 1, and a bracket 11 is fixedly installed on one side of the base 1. The base 1 is equipped with several cameras 12. A cleaning brush 13 is rotatably installed on one side of the base 1. A collection box 14 is set on one side of the base 1. A mud pump 15 is set on one side of the collection box 14. A conveying pipe 16 is fixedly installed at the outlet of the mud pump 15. One end of the outlet of the conveying pipe 16 passes through one side of the base 1 and is located above the feeding hopper 5. A leveling device 2 is set on the inner wall of the base 1 between the feeding hopper 5 and the spray pipe frame 6. The leveling device 2 can drive the round rod 21 and the striking rod 22 to knock and vibrate the conveyor belt 4 at intervals, so that the quartz sand conveyed on the conveyor belt 4 is not easy to accumulate. At the same time, it is scraped off and leveled by the leveling scraper 243, so as to facilitate full contact with solvent oil later. Quartz sand particles of a certain size are placed into the feeding hopper 5, and then fall onto the conveyor belt 4 through the feeding hopper 5. At this time, the drive motor on the base 1 is started to drive the circular shaft 3 to rotate, thereby driving the conveyor belt 4 to convey the quartz sand particles. When conveyed to a certain position, the leveling device 2 can vibrate and level the stacked quartz sand particles, spreading them flat on the conveyor belt 4, and then continue to convey them. When passing under the spray pipe frame 6, the oil pump 8 can be started to draw the solvent oil from the storage tank into the spray pipe frame 6 and spray it out, so that the solvent oil is evenly sprayed onto the sand surface, allowing the quartz sand to be fully wetted by the solvent oil. Because the refractive index of the solvent oil is basically the same as that of natural quartz, quartz sand particles without gas-liquid inclusions or with a small amount of gas-liquid inclusions become transparent after being wetted by the solvent oil, while those with gas-liquid inclusions... Quartz sand particles with a higher volume appear milky white and opaque after being soaked in solvent oil. When the quartz sand sprayed with solvent oil is conveyed to the lower end of the camera 12, the camera 12 identifies the quartz sand of different colors and transmits signals to the control box 9. The control box 9 then directs the robotic arm to pick out the milky white and opaque quartz sand particles. The quartz sand particles with higher transparency continue to be conveyed. When they are conveyed to a certain position, the drive motor on the base 1 is started to drive the cleaning brush 13 to rotate and sweep them into the collection box 14 for degreasing and purification treatment, resulting in high-purity quartz sand with a low content of gas-liquid inclusions. In order to improve the removal and processing effect and purity, the quartz sand particles that fall into the collection box 14 are generally pumped back into the conveying pipe 16 by the mud pump 15, and then fall back into the feed hopper for secondary removal and processing.

[0041] Figure 1-5 The leveling device 2 shown includes a round rod 21, with both ends of the round rod 21 respectively penetrating and installed on both sides of the inner wall of the base 1; several striking rods 22, with one side of the striking rods 22 fixedly installed on the outer surface of the round rod 21; a driving mechanism 23, which is disposed between one side of the round rod 21 and the inner wall of the base 1, for driving the round rod 21 and several striking rods 22 to perform intermittent striking and vibration treatment on the conveyor belt 4; and an auxiliary mechanism 24, which is disposed on one side of the base 1 above the conveyor belt 4, for leveling the conveyed quartz sand particles. By setting up the leveling device 2, the auxiliary mechanism 24 is first adjusted to a certain height. Then, quartz sand particles of a certain size are put into the feeding hopper 5 and fall onto the conveyor belt 4 through the feeding hopper 5. At this time, the drive motor on the base 1 is started to drive the round shaft 3 to rotate, which can drive the conveyor belt 4 to convey the quartz sand particles. When the particles are conveyed to a certain position, the drive mechanism 23 can be started to drive the round rod 21 and several striking rods 22 to knock and vibrate the conveyor belt 4 at intervals, so that the quartz sand conveyed on the conveyor belt 4 is vibrated and dispersed, making it less likely to accumulate. At the same time, with the help of the auxiliary mechanism 24, it is scraped away and leveled, which facilitates full contact with solvent oil in the later stage, effectively removes gas-liquid inclusions, improves the purity of quartz sand, processing effect and quality of final product.

[0042] Figure 1-5 The striking rod 22 shown has reinforcing rods 26 fixedly installed on both sides of one end, with one side of the reinforcing rod 26 fixedly installed on the outer surface of the round rod 21. By setting the reinforcing rods 26, the connection area between the striking rod 22 and the round rod 21 can be increased, making the connection more secure and stable, and less prone to breakage or damage. A protective block 25 made of rubber is fixedly installed on the outer surface of one end of the striking rod 22. By setting the protective block 25, the impact wear between one end of the striking rod 22 and the conveyor belt 4 can be reduced, preventing damage to the conveyor belt 4.

[0043] Figure 1-5The drive mechanism 23 shown includes a spur gear 231, the inner wall of which is fixedly mounted on the outer surface of one end of a round rod 21; a torsion spring 232, the inner wall of which is sleeved on the outer surface of one end of the round rod 21, and both ends are fixedly mounted on one side of the spur gear 231 and one side of the base 1, respectively; and a servo motor 233, one side of which is fixedly mounted on one side of the base 1, and a sector gear 234 is fixedly mounted on the output end of the servo motor 233 via a coupling, wherein the outer surface of the sector gear 234 meshes with the outer surface of the spur gear 231. When removing gas-liquid inclusions from high-purity quartz sand particles using the drive mechanism 23, the servo motor 233 can be activated to drive the sector gear 234 to rotate, which in turn intermittently drives the spur gear 231 to rotate. Then, in conjunction with the deformation and reset of the torsion spring 232, the circular rod 21 and several striking rods 22 can be driven to rotate intermittently left and right, thereby intermittently striking the inner wall of the conveyor belt 4, vibrating and spreading the quartz sand particles conveyed on its surface to prevent accumulation and maintain the removal effect. A protective cover 235 is fixedly installed on one side of the base 1. The servo motor 233, spur gear 231, torsion spring 232, and sector gear 234 are all housed within the inner wall of the protective cover 235. By installing the protective cover 235, impurities in the air can be effectively prevented from falling between the spur gear 231 and the sector gear 234, avoiding jamming and affecting rotation.

[0044] Figure 1-5 The auxiliary mechanism 24 shown includes a screw hole frame 241, both sides of which are fixedly mounted on one side of the base 1; a threaded rod 242, one end of which is helically inserted into the inner wall of the screw hole frame 241; and a leveling scraper 243, one side of which is rotatably mounted on one side of the threaded rod 242. By setting up the auxiliary mechanism 24, after the quartz sand particles fall onto the conveyor belt 4 from the main feed hopper, the threaded rod 242 can be rotated on the screw hole frame 241 to a certain angle according to actual usage requirements. This adjusts the height of one side of the leveling scraper 243 from the top of the conveyor belt 4 to allow a thin layer of quartz sand particles to pass through. This effectively prevents the accumulation of quartz sand particles, allowing the subsequent solvent oil to fully contact the conveyed quartz sand particles, effectively removing gas-liquid inclusions, improving the purity and processing effect of the quartz sand, and enhancing the quality of the final product. A bearing 244 is fixedly mounted on one end of the threaded rod 242, and the outer ring of the bearing 244 is fixedly mounted on one side of the leveling scraper 243. By setting the bearing 244, the rotational wear between the threaded rod 242 and the leveling scraper 243 can be reduced, thereby improving the service life of both.

[0045] Working principle: After the quartz sand particles fall onto the conveyor belt 4 from the main feed hopper, the threaded rod 242 can be rotated to a certain angle on the screw hole frame 241 according to actual usage requirements. This leveles the distance between one side of the scraper 243 and the top of the conveyor belt 4, allowing a thin layer of quartz sand particles to pass through. Then, quartz sand particles of a certain size are placed into the feed hopper 5 and fall onto the conveyor belt 4 through the feed hopper 5. The servo motor 233 is started to drive the sector gear 234 to rotate, which in turn drives the circular gear 231 to rotate intermittently. With the deformation and reset of the torsion spring 232, the circular rod 21 and several striking rods 22 can be driven to rotate left and right intermittently, striking and vibrating the conveyor belt 4. This causes the quartz sand conveyed on the conveyor belt 4 to vibrate and disperse, preventing accumulation. At the same time, with the help of the auxiliary mechanism 24, it is scraped away and leveled, facilitating full contact with the solvent oil later, effectively removing gas-liquid inclusions, improving the purity of the quartz sand, the processing effect, and the quality of the final product. Then, the conveying continues. As it passes below the nozzle frame 6, the oil pump 8 can be activated to draw solvent oil from the storage tank into the nozzle frame 6 and spray it out, evenly coating the sand surface. This ensures the quartz sand is fully wetted. Because the refractive index of the solvent oil is essentially the same as that of natural quartz, quartz sand particles without or with only a small amount of gas-liquid inclusions become transparent after being wetted. Conversely, quartz sand particles with more gas-liquid inclusions become milky white and opaque. Thus, when the solvent-oil-sprayed quartz sand is conveyed to the lower end of the camera 12, different colors of quartz sand are captured. Camera 12 identifies and transmits signals to control box 9, which then directs the robotic arm to pick out the milky white, opaque quartz sand particles. The quartz sand particles with high transparency continue to be conveyed. When they reach a certain position, the drive motor on base 1 is activated to rotate the cleaning brush 13, sweeping them into collection box 14 for degreasing and purification, resulting in high-purity quartz sand with a low content of gas-liquid inclusions. To improve the removal and processing effect and purity, the quartz sand particles that fall into collection box 14 are usually pumped back into conveying pipe 16 by mud pump 15, and then fall back into feed hopper for secondary removal and processing.

10. A method for removing gas-liquid inclusions from high-purity quartz sand by oil immersion treatment, characterized in that, An apparatus for removing gas-liquid inclusions from high-purity quartz sand using oil immersion treatment according to any one of claims 1-9, comprising the following steps: S1. First, according to the particle size of the quartz sand to be processed, turn the threaded rod (242) on the screw hole frame (241) in the auxiliary mechanism (24), adjust the distance between the leveling scraper (243) and the top of the conveyor belt (6) through the bearing (244) to ensure that only a thin layer of quartz sand is allowed to pass through. At the same time, check the solvent oil storage in the storage tank (7), confirm that the oil pump (8), servo motor, camera (12), robotic arm (10) and other components are connected normally, and start the control box (9) to initialize the equipment parameters. S2. Place high-purity quartz sand particles of a certain size into the feed hopper, start the drive motor on the base (1) to drive the round shaft (3) to rotate, so that the conveyor belt (4) runs. The quartz sand falls evenly onto the conveyor belt (4) through the feed hopper and is conveyed towards the nozzle frame (6) along with the conveyor belt (4). S3. Start the drive mechanism (23) of the leveling device (2). The servo motor (233) drives the sector gear (234) to rotate. The intermittent meshing of the round gear (231) and the deformation and reset of the torsion spring (232) drive the round rod (21) and the striking rod (22) to strike the conveyor belt (4) intermittently, causing the accumulated quartz sand to vibrate and disperse. At the same time, the leveling scraper (243) scrapes the quartz sand on the conveyor belt (4) to flatten it and prevent accumulation. S4. When the leveled quartz sand is transported to the bottom of the spray frame (6), start the oil pump (8) to extract the solvent oil in the storage tank (7) and transport it to the spray frame (6). Spray the solvent oil evenly on the surface of the quartz sand through the spray frame (6) to fully wet the quartz sand. S5. The soaked quartz sand continues to be conveyed to the area below the camera (12). The camera (12) identifies the color of the quartz sand and transmits the signal to the control box (9). The control box (9) instructs the robotic arm (10) to pick out and remove the milky white opaque quartz sand particles, leaving the transparent particles. S6. When qualified quartz sand is delivered to the end, start the drive motor to drive the cleaning brush (13) to rotate and sweep the quartz sand into the collection box (14). Start the mud pump (15) to pump the quartz sand in the collection box (14) back to the feed hopper through the conveying pipe (16) for secondary oil immersion treatment to improve purity. S7. After multiple treatments, the quartz sand in the collection box (14) is de-oiled to remove residual solvent oil on the surface, and then purified to finally obtain high-purity quartz sand with very low gas-liquid inclusion content.
