[0002] Quartzite is a new type of stone artificially synthesized from more than 90% quartz crystals plus resin and other trace elements. It is a large-sized plate pressed by a special machine under certain physical and chemical conditions. Quartzite has many advantages. Its hardness is extremely high, with a Mohs hardness of about 7 degrees, second only to diamond, and it is not easily scratched, making it very suitable for use in places such as kitchens where hard objects are often used. Its surface is smooth and dense without pores, making it difficult for bacteria, oil stains, etc. to penetrate, and it is very convenient to clean, effectively ensuring household hygiene. Moreover, it has good high-temperature resistance and can withstand a high temperature of about 300°C for a short time without deformation or fading. In terms of appearance, quartzite has a rich variety of colors and textures to choose from, meeting the needs of different decoration styles. Because of its combination of beauty and practicality, it is widely used in indoor decoration fields such as kitchen countertops, bathroom countertops, and window sills, and has become one of the popular materials in modern home decoration.

[0014] A method for using a device for preparing high-purity quartz sand from quartz stone specifically includes the following steps:
[0015] S1. Raw material preparation: Prepare quartz stone solid raw materials and auxiliary additives;
[0016] S2. Preliminary grinding: Put the quartz stone solid raw materials and auxiliary additives into the rotating inner cylinder, start the servo motor, the output shaft of the servo motor drives the transmission gear to rotate, the transmission gear is meshed with the driving gear, so that the driving gear drives the whole rotating outer cylinder to rotate concentrically. While the rotating outer cylinder rotates, the rotating ring fixedly connected to the side of the rotating outer cylinder also rotates concentrically, so that the rotating inner cylinder fixedly connected to one side of the fixed ring rotates concentrically. At the same time, the driving ring fixedly connected to the side of the rotating ring rotates, and the tooth grooves on the inner wall of the driving ring are meshed with the second gear for transmission, the second gear is meshed with the first gear for transmission, so as to drive the driving grinding roller and the eccentric grinding roller to rotate relatively, the grinding convex balls on the side of the driving grinding roller and the eccentric grinding roller move alternately, the grinding convex balls cooperate with the first-stage grinding stones and contact the quartz stone raw materials, so that the quartz stone raw materials are initially ground in the rotating inner cylinder;
[0017] S3. Preliminary filtration: During the grinding process of the rotating inner cylinder, when the first material tank is butted against the second material tank, the quartz stone solid raw materials meeting the particle size pass through the filter screen and enter the inside of the rotating outer cylinder;
[0018] S4. Fine grinding: During the rotation of the outer cylinder, due to the cooperation of the rectangular cylinder with the first fixed track groove, the second fixed track groove, the first sliding rod, and the second sliding rod, its angle remains fixed. The first sliding rod on the side of the sliding plate moves along the variable track groove, causing the sliding plate to expand and contract. When the sliding plate retracts, the ejection plate is driven closer to the wall of the rotating outer cylinder, reducing the angle between the ejection plate and the wall of the rotating outer cylinder, and decreasing the inclination angle of the secondary grinding stone, which is not conducive to the sliding of the secondary grinding stone and helps to extend the residence time of the secondary grinding stone at the high position of the rotating outer cylinder, thereby helping the secondary grinding stone to increase its potential energy. When the sliding plate extends, the angle between the ejection plate and the wall of the rotating outer cylinder increases. At this time, the ejection plate is located at the bottom side inside the rotating outer cylinder, and at this time, the secondary grinding stone falls on the ejection plate and rebounds to contact the quartz multiple times, enabling the solid raw material of the quartz stone to be ground for the second time;
[0019] S5. Collection and storage: Pour the prepared quartz sand into a container, seal it, and label it. During storage, avoid direct sunlight and moisture, and do not directly contact the ground to prevent the quartz sand from being contaminated.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] 1. By setting the driving grinding roller and the eccentric grinding roller inside the primary grinding mechanism of the present invention, the grinding convex balls cooperate with the primary grinding stone and contact the quartz stone raw material. The driving grinding roller and the eccentric grinding roller achieve staggered movement through reverse meshing of gears. The grinding convex balls and the primary grinding stone form dynamic extrusion, accelerating the speed of primary grinding.
[0022] 2. By setting the rotating inner cylinder and the fixed inner cylinder inside the primary grinding mechanism of the present invention, the rough inner wall can increase the friction with the material and the grinding medium. Combined with the co-rotation of the driving grinding roller, it promotes the more uniform distribution of the material in the cylinder under the action of centrifugal force, reducing local accumulation, thereby improving the grinding efficiency. The eccentric grinding roller rotates in the opposite direction to the inner cylinder, forming a shear force difference and accelerating the material crushing process. This setting can effectively reduce the residual rate of coarse particles and improve the consistency of the finished product particle size.
[0023] 3. By setting the ejection component of the present invention, the rebound movement of the secondary grinding stone on the ejection plate increases the contact frequency and strength with the quartz stone, enabling the quartz stone particles to be more fully crushed and refined, thereby improving the grinding efficiency. Through multiple contacts, the grinding of the quartz stone raw material is more uniform, avoiding the problem of uneven particle sizes and improving the quality of the final product.

[0040] Grinding convex balls 3022 are fixedly connected to the sides of the driving grinding roll 301 and the eccentric grinding roll 302.
[0041] The specific implementation manner of this embodiment is as follows: The solid raw material of quartz stone and auxiliary additives are put into the rotating inner cylinder 305. The servo motor 2011 is started. The output shaft of the servo motor 2011 drives the transmission gear 202 to rotate. The transmission gear 202 is meshed with the driving gear 101, so that the driving gear 101 drives the entire rotating outer cylinder 10 to rotate concentrically. While the rotating outer cylinder 10 rotates, the rotating ring 1032 fixedly connected to the side of the rotating outer cylinder 10 also rotates concentrically, so that the rotating inner cylinder 305 fixedly connected to the side of the fixed ring rotates concentrically. At the same time, the driving ring 1033 fixedly connected to the side of the rotating ring 1032 rotates. The tooth grooves 1034 on the inner wall of the driving ring 1033 are meshed and driven with the second gear 3021, and the second gear 3021 and the first gear 3031 are meshed and driven, thereby driving the driving grinding roll 301 and the eccentric grinding roll 302 to rotate relatively.

The driving grinding roll 301 and the eccentric grinding roll 302 achieve alternating movement through reverse meshing of gears. The grinding convex balls 3022 and the primary grinding stones 303 form a dynamic extrusion and shear force field, accelerating the speed of primary grinding.
[0042] Example 2: Please refer to Figure 4 - Figure 5 The present invention provides a technical solution: A device for preparing high-purity quartz sand from quartz stone. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The primary grinding mechanism 30 further includes a fixed inner cylinder 304 and a rotating inner cylinder 305 disposed in the inner cavity of the rotating outer cylinder 10. The fixed inner cylinder 304 and the rotating inner cylinder 305 are jointly used for screening quartz stones.
[0043] As a further limitation of the primary grinding mechanism 30 of the present invention, one end of the rotating inner cylinder 305 is fixedly connected to the side of the rotating ring 1032. The rotating inner cylinder 305 rotates synchronously with the rotating ring 1032. The fixed inner cylinder 304 is sleeved outside the rotating inner cylinder 305. One end of the fixed inner cylinder 304 is fixedly connected to the side of the fixed disk 1031. The side parts of the fixed inner cylinder 304 and the rotating inner cylinder 305 are respectively provided with a first material groove 3051 and a second material groove 3052.

[0044] The specific implementation of this embodiment is as follows: During the grinding process of the rotating inner cylinder 305, the inner wall of the rotating outer cylinder 10 is set as a rough surface. The rotating direction of the rotating inner cylinder 305 is the same as that of the driving grinding roller 301 and opposite to that of the eccentric grinding roller 302. The rough inner wall can increase the friction force with the material and the grinding medium. Combined with the same-direction rotation of the driving grinding roller 301, it promotes the more uniform distribution of the material in the cylinder under the action of centrifugal force, reduces local accumulation, and thus improves the grinding efficiency. The eccentric grinding roller 302 rotates in the opposite direction to the inner cylinder, forming a shear force difference to accelerate the material crushing process. This setting can effectively reduce the residual rate of coarse particles and improve the consistency of the finished product particle size. When the first material groove 3051 is docked with the second material groove 3052, the quartz solid raw material meeting the particle size passes through the filter screen 3053 and enters the inside of the rotating outer cylinder 10.
[0045] Example 3: Please refer to Figures 6 - 10 , the present invention provides a technical solution: A device for preparing high-purity quartz sand from quartz stone. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The ejection assembly 40 includes a rotating shaft 404 provided on the inner wall of the rotating outer cylinder 10 and an ejection plate 401 rotatably installed outside the rotating shaft 404. The ejection assembly 40 includes a number of secondary grinding stones 403 provided in the inner cavity of the rotating outer cylinder 10. The ejection plate 401 is used to eject the secondary grinding stones 403.
[0046] As a further limitation of the ejection component 40 of the present invention, the rotating shaft 404 is rotatably connected to the inner wall of the rotating outer cylinder 10, the ejection plate 401 is rotatably connected to the outside of the rotating shaft 404, the inner wall of one end of the ejection plate 401 away from the rotating shaft 404 is rotatably connected with a sliding plate 4011, the inner wall of the rotating outer cylinder 10 is fixedly connected with a rectangular cylinder 4012, the sliding plate 4011 is slidably connected to the inside of the rectangular cylinder 4012, a return spring 4013 is fixedly connected between the rectangular cylinder 4012 and the sliding plate 4011, a first fixed track groove 4014, a second fixed track groove 4015 and a variable track groove 4016 are provided on the side of the fixed disk 1031, a first sliding rod 4018 is fixedly connected to the side of the sliding plate 4011, a second sliding rod 4019 and a third sliding rod 4020 are respectively connected to the side of the rectangular cylinder 4012, the first sliding rod 4018 is slidably connected to the variable track groove 4016, the second sliding rod 4019 is slidably connected to the first fixed track groove 4014, and the third sliding rod 4020 is slidably connected to the second fixed track groove 4015.
[0047] The first fixed track groove 4014 and the second fixed track groove 4015 are provided as annular sliding grooves concentric with the fixed disk 1031. The variable track groove 4016 is divided into a short-end sliding groove 4041, a connecting sliding groove 4042 and a long-end sliding groove 4043. The circle where the short-end sliding groove 4041 is located is concentric with the circle where the long-end sliding groove 4043 is located. The distance between the short-end sliding groove 4041 and the first fixed track groove 4014 is greater than the distance between the long-end sliding groove 4043 and the first fixed track groove 4014. The connecting sliding groove 4042 is connected between the short-end sliding groove 4041 and the long-end sliding groove 4043.
[0048] The specific implementation of this embodiment is as follows: During the rotation of the rotating outer cylinder 10, due to the cooperation of the rectangular cylinder 4012, the first fixed track groove 4014, the second fixed track groove 4015, the first sliding rod 4018 and the second sliding rod 4019, its angle will remain fixed. The first sliding rod 4018 on the side of the sliding plate 4011 moves along the variable track groove 4016, causing the sliding plate 4011 to expand and contract. When the sliding plate 4011 retracts, the ejection plate 401 is driven closer to the wall surface of the rotating outer cylinder 10, reducing the angle between the ejection plate 401 and the wall surface of the rotating outer cylinder 10 and the inclination angle of the secondary grinding stone 403, which is not conducive to the secondary grinding stone 403 sliding down, helping to extend the residence time of the secondary grinding stone 403 at the high position of the rotating outer cylinder 10, thereby helping the secondary grinding stone 403 increase its potential energy. When the sliding plate 4011 extends, the angle between the ejection plate 401 and the wall surface of the rotating outer cylinder 10 increases. At this time, the ejection plate 401 is located at the bottom side inside the rotating outer cylinder 10. The rebound movement of the secondary grinding stone 403 on the ejection plate 401 increases the contact frequency and force with the quartz stone, enabling the quartz stone particles to be more fully broken and refined, thereby improving the grinding efficiency. Through multiple contacts, the grinding of the quartz stone raw material is more uniform, avoiding the problem of uneven particle sizes and improving the quality of the final product.
[0049] A method for using a device for preparing high-purity quartz sand from quartz stone specifically includes the following steps:
[0050] S1. Raw material preparation: Prepare solid quartz stone raw materials and auxiliary additives;
[0051] S2. Preliminary grinding: Put the solid quartz stone raw materials and auxiliary additives into the rotating inner cylinder 305. Start the servo motor 2011. The output shaft of the servo motor 2011 drives the transmission gear 202 to rotate. The transmission gear 202 is meshed with the driving gear 101, causing the driving gear 101 to drive the entire rotating outer cylinder 10 to rotate concentrically. While the rotating outer cylinder 10 rotates, the rotating ring 1032 fixedly connected to the side of the rotating outer cylinder 10 also rotates concentrically, thereby causing the rotating inner cylinder 305 with one end fixedly connected to the side of the fixed ring to rotate concentrically. At the same time, the driving ring 1033 fixedly connected to the side of the rotating ring 1032 rotates. The tooth groove 1034 on the inner wall of the driving ring 1033 is in meshing transmission with the second gear 3021, and the second gear 3021 is in meshing transmission with the first gear 3031, thereby driving the driving grinding roller 301 and the eccentric grinding roller 302 to rotate relatively. The grinding convex balls 3022 on the sides of the driving grinding roller 301 and the eccentric grinding roller 302 move alternately. The grinding convex balls 3022 cooperate with the primary grinding stone 303 and contact the quartz stone raw materials, enabling the quartz stone raw materials to complete the primary grinding in the rotating inner cylinder 305;
[0052] S3. Preliminary filtration: During the grinding process of the rotating inner cylinder 305, when the first material tank 3051 is docked with the second material tank 3052, the quartz solid raw materials meeting the particle size pass through the filter screen 3053 and enter the rotating outer cylinder 10;
[0053] S4. Fine grinding: During the rotation of the rotating outer cylinder 10, due to the cooperation of the first fixed track groove 4014, the second fixed track groove 4015, the first sliding rod 4018 and the second sliding rod 4019, the angle of the rectangular cylinder 4012 will remain fixed. The first sliding rod 4018 on the side of the sliding plate 4011 moves along the variable track groove 4016, causing the sliding plate 4011 to expand and contract. When the sliding plate 4011 retracts, the ejection plate 401 is driven closer to the wall of the rotating outer cylinder 10, reducing the angle between the ejection plate 401 and the wall of the rotating outer cylinder 10 and the inclination angle of the secondary grinding stone 403, which is not conducive to the secondary grinding stone 403 sliding down, helping to extend the residence time of the secondary grinding stone 403 at the high position of the rotating outer cylinder 10, thereby helping the secondary grinding stone 403 increase its potential energy. When the sliding plate 4011 extends, the angle between the ejection plate 401 and the wall of the rotating outer cylinder 10 becomes larger. At this time, the ejection plate 401 is located at the bottom side inside the rotating outer cylinder 10. At this time, the secondary grinding stone 403 falls on the ejection plate 401 and rebounds to contact the quartz multiple times, enabling the quartz solid raw materials to be secondarily ground;

10. A method for using the device for preparing high-purity quartz sand from quartz stone according to any one of claims 1 to 9, characterized in that: The specific steps include: S1. Raw material preparation: prepare quartz stone solid raw materials and auxiliary additives; S2, preliminary grinding: quartz stone solid raw material and auxiliary additives are placed into the rotating inner cylinder (305), and the servo motor (211) is started. The output shaft of the servo motor (211) drives the transmission gear (202) to rotate. The transmission gear (202) is meshed with the driving gear (101), so that the driving gear (101) drives the entire rotating outer cylinder (10) to rotate concentrically. When the rotating outer cylinder (10) rotates, the rotating ring (1032) fixedly connected to the side of the rotating outer cylinder (10) also rotates concentrically, so that the rotating inner cylinder (305) with one end fixedly connected to the side of the fixed ring rotates concentrically. At the same time, the rotating ring (1032) fixedly connected to the rotating outer cylinder (10) rotates concentrically. The driving ring (1033) on the side of the ring (1032) rotates, the tooth groove (1034) on the inner wall of the driving ring (1033) meshes with the second gear (3021) for transmission, and the second gear (3021) meshes with the first gear (3031) for transmission, thereby driving the driving grinding roller (301) and the eccentric grinding roller (302) to rotate relative to each other, and the grinding convex balls (3022) on the sides of the driving grinding roller (301) and the eccentric grinding roller (302) move alternately with each other, and the grinding convex balls (3022) cooperate with the primary grinding stone (303) and contact with the quartz raw material, so that the quartz raw material completes the initial grinding in the rotating inner cylinder (305); S3, preliminary filtration: during the grinding process of the rotating inner cylinder (305), when the first material trough (3051) and the second material trough (3052) are connected, the quartz stone solid raw material of the particle size meets the requirements and passes through the filter screen (3053) and enters the interior of the rotating outer cylinder (10); S4, fine grinding: During the rotation of the rotating outer cylinder (10), the angle of the rectangular cylinder (4012) remains fixed due to the cooperation of the first fixed track groove (4014), the second fixed track groove (4015), the first sliding rod (4018) and the second sliding rod (4019). The first sliding rod (4018) on the side of the sliding plate (4011) moves along the variable track groove (4016), so that the sliding plate (4011) can be extended and retracted. When the sliding plate (4011) retracts, the ejection plate (401) is driven closer to the wall of the rotating outer cylinder (10), so that the ejection plate (401) and the rotating outer cylinder are in contact. (10) The wall angle becomes smaller, and the inclination angle of the secondary grinding stone (403) becomes smaller, which is not conducive to the secondary grinding stone (403) sliding down, and helps to extend the residence time of the secondary grinding stone (403) at the high point of the rotating outer cylinder (10), thereby helping the secondary grinding stone (403) to increase its potential energy. When the sliding plate (4011) is extended, the angle between the ejection plate (401) and the wall of the rotating outer cylinder (10) becomes larger. At this time, the ejection plate (401) is located at the bottom side of the rotating outer cylinder (10). At this time, the secondary grinding stone (403) falls on the ejection plate (401) and rebounds to contact the quartz multiple times, so that the quartz solid raw material is ground twice; S5. Collection and storage: Pour the prepared quartz sand into a container, seal it and label it. During storage, be careful to avoid direct sunlight and moisture, and do not let it come into direct contact with the ground to prevent the quartz sand from being contaminated.
