Description

Technical Field

[0001] This invention belongs to the field of quartz sand sorting technology, specifically relating to an intelligent quartz sand sorting machine. Background Technology

[0002] Quartz sand is a core raw material in photovoltaic, semiconductor, glass manufacturing, building materials and other fields. Its particle size uniformity directly affects the quality and performance of end products. The particle size sorting of quartz sand is a key process in the quartz sand processing. Current methods for quartz sand particle size separation mainly rely on single screening equipment. This equipment separates large-particle quartz sand from small-particle quartz sand based on the screen's mesh size, collecting only the small-particle quartz sand that meets the required particle size. The separated large-particle quartz sand faces two treatment options: First, it is directly discarded as waste, resulting in significant waste of material resources, especially for high-purity raw materials like high-quality quartz sand, where waste disposal significantly increases production costs. Second, it is separately transported to a dedicated grinding device for crushing. The ground material then needs to be manually transferred to a small-particle quartz sand collection device, increasing transportation and labor costs. Furthermore, the ground material lacks targeted particle size verification, easily mixing in insufficiently ground large particles, leading to poor particle size consistency in the final product and failing to meet the requirements of high-precision applications. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose an intelligent quartz sand sorting machine, which can crush large-particle quartz sand after sorting, reducing the waste of material resources.

[0004] The intelligent quartz sand separator of this invention includes: A screening mechanism, comprising a screen cylinder open at both ends, the screen cylinder having multiple screen holes, the screen cylinder being inclined in the vertical direction, and the screen cylinder being used for screening quartz sand; A grinding mechanism includes a grinding cylinder with one end open, the grinding cylinder being connected to the bottom end of the sieve cylinder, the grinding cylinder being used to receive large-particle quartz sand that has not passed through the sieve holes, and a grinding element being rotatably disposed in the grinding cylinder for grinding the large-particle quartz sand in the grinding cylinder; A support mechanism, comprising a support member and a telescopic member, wherein the support member is connected to the grinding mechanism and is used to support the grinding mechanism, and the telescopic member is connected to the upper end of the screen cylinder and is used to adjust the tilt angle of the screening mechanism; In this process, after the quartz sand is sorted by the sieve cylinder, the larger particles of quartz sand enter the grinding mechanism for grinding. After grinding, the telescopic component changes the tilt angle of the sieve cylinder so that the ground quartz sand in the grinding cylinder passes through the sieve cylinder again for sieving.

[0005] The intelligent quartz sand separator of this invention, through the linkage design of the screening and grinding mechanisms, directly feeds large-particle quartz sand that has not passed screening into the grinding device for secondary processing. This avoids the resource waste caused by discarding large-particle raw materials in traditional single screening equipment. It is especially suitable for processing high-purity quartz sand and other high-quality raw materials, significantly reducing production costs. By flexibly adjusting the tilt angle of the screening mechanism through the telescopic component, the automatic return and secondary screening of the ground material is achieved, eliminating the need for manual transfer of the ground material. This saves on additional investment in conveying equipment and labor costs, and improves the continuity and automation of quartz sand sorting and processing. The stable support of the grinding mechanism by the support component and the precise control of the screening angle by the telescopic component ensure the coordinated and efficient operation of the screening and grinding processes, improving the overall stability and reliability of the equipment and reducing the probability of downtime during processing.

[0006] In some embodiments, the intelligent quartz sand sorting machine further includes a dust suppression mechanism, which includes a dust suppression pipe coaxially arranged with the grinding element. The dust suppression pipe has multiple dust suppression holes, and a connecting sleeve is rotatably provided at one end of the dust suppression pipe. The connecting sleeve is connected to a dust collection device.

[0007] In some embodiments, the dust suppression mechanism further includes a plurality of stirring rods disposed on the dust suppression pipe, the stirring rods being used to stir the quartz sand in the screen cylinder.

[0008] In some embodiments, the screening mechanism further includes a material cylinder with one end open, the material cylinder being in communication with the screen cylinder, and a feed hole being provided on the circumferential side of the material cylinder for adding the quartz sand into the screen cylinder, and a detachable cover being connected to the feed hole.

[0009] In some embodiments, the screening mechanism further includes a discharge port, which is located at one end of the material cylinder away from the screen cylinder. The discharge port is used to discharge the material that has not been ground by the grinding mechanism, and a plug is detachably connected to the discharge port.

[0010] In some embodiments, the screening mechanism further includes a rotary motor, the output end of which is connected to the material cylinder. The rotary motor is used to drive the screen cylinder to rotate and is connected to the telescopic member.

[0011] In some embodiments, the grinding element includes a grinding base, the end of the grinding base near the sieve cylinder being a frustoconical section, the end of the grinding base away from the sieve cylinder being a cylindrical section, and a plurality of grinding blocks being disposed on the grinding base.

[0012] In some embodiments, the grinding element further includes a rotating shaft, the grinding seat is fixedly sleeved on the rotating shaft, the rotating shaft extends out of the grinding cylinder, a driven gear is sleeved on the extended end of the rotating shaft, and a driving gear is provided on the grinding cylinder, the driving gear being connected to the output end of the drive motor.

[0013] In some embodiments, the support member includes a sliding sleeve fitted on the grinding cylinder, two support rods rotatably connected to the sliding sleeve, and a support plate fixedly connected to the bottom end of the two support rods; the telescopic member includes a support sleeve fitted on the rotating motor, two telescopic rods rotatably connected to the support sleeve, and a connecting plate fixedly connected to the bottom end of the two telescopic rods; a receiving hopper is provided on the lower side of the screen cylinder.

[0014] The intelligent quartz sand sorting method of this invention, utilizing the intelligent quartz sand sorting device of any of the above embodiments, includes the following steps: Initial screening process: The quartz sand to be sorted is passed into the upper opening of the screen cylinder. Multiple screen holes on the screen cylinder are used to sort the quartz sand by particle size. The quartz sand that meets the particle size requirements passes through the screen holes and is sorted. The large-sized quartz sand that does not pass through the screen holes slides down the inclined screen cylinder into the grinding cylinder of the grinding mechanism connected to the bottom of the screen cylinder. Large particle size grinding process: Start the rotating grinding element inside the grinding cylinder to grind the large particle size quartz sand that enters the grinding cylinder until the large particle size quartz sand reaches the preset grinding particle size; Secondary screening process: The tilt angle of the screen cylinder is changed by the telescopic component, so that the quartz sand ground in the grinding cylinder flows back to the screen cylinder and is screened again through the screen holes, thus completing the intelligent sorting of quartz sand.

[0015] The intelligent quartz sand sorting method of this invention, through the pre-treatment of initial screening, first completes the rapid sorting of qualified quartz sand particles, reducing the processing volume of subsequent grinding processes and improving the overall sorting efficiency; through the grinding treatment with preset grinding particle size, large-particle quartz sand is specifically ground to ensure that the particle size of the ground quartz sand is more in line with application requirements, thus improving product quality; through the post-verification of secondary screening, the particle size of the ground material is strictly re-inspected, effectively removing large particles that do not meet the standards, ensuring the particle size uniformity and consistency of the final product; through the standardized process design of "screening-grinding-secondary screening", the quartz sand sorting is automated and closed-loop, eliminating the need for manual intervention in the connection of each process, reducing labor costs, and improving the standardization of sorting processing.

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1-8 As shown, the intelligent quartz sand sorting machine of this invention includes... Screening mechanism 1 includes a screen cylinder 11 with openings at both ends. The screen cylinder 11 has multiple screen holes 12. The screen cylinder 11 is inclined in the vertical direction and is used to screen quartz sand. Grinding mechanism 2 includes a grinding cylinder 21 with one end open. The grinding cylinder 21 is connected to the bottom end of the sieve cylinder 11. The grinding cylinder 21 is used to receive large-particle quartz sand that has not passed through the sieve hole 12. A grinding element 22 is rotatably arranged in the grinding cylinder 21. The grinding element 22 is used to grind the large-particle quartz sand in the grinding cylinder 21. Support mechanism 3 includes support member 31 and telescopic member 32. Support member 31 is connected to grinding mechanism 2 and is used to support grinding mechanism 2. Telescopic member 32 is connected to the upper end of screen cylinder 11 and is used to adjust the tilt angle of screening mechanism 1. In this process, after the quartz sand is sorted by the screen cylinder 11, the larger particles of quartz sand enter the grinding mechanism 2 for grinding. After grinding, the telescopic component 32 changes the inclination angle of the screen cylinder 11 so that the quartz sand ground in the grinding cylinder 21 passes through the screen cylinder 11 again for sieving.

[0027] The intelligent quartz sand separator of this invention, through the linkage design of the screening and grinding mechanisms, directly feeds large-particle quartz sand that has not passed screening into the grinding device for secondary processing. This avoids the resource waste caused by discarding large-particle raw materials in traditional single screening equipment. It is especially suitable for processing high-purity quartz sand and other high-quality raw materials, significantly reducing production costs. By flexibly adjusting the tilt angle of the screening mechanism through the telescopic component, the automatic return and secondary screening of the ground material is achieved, eliminating the need for manual transfer of the ground material. This saves on additional investment in conveying equipment and labor costs, and improves the continuity and automation of quartz sand sorting and processing. The stable support of the grinding mechanism by the support component and the precise control of the screening angle by the telescopic component ensure the coordinated and efficient operation of the screening and grinding processes, improving the overall stability and reliability of the equipment and reducing the probability of downtime during processing.

[0028] Specifically, the quartz sand to be sorted is fed into the upper opening of a vertically inclined screen cylinder 11. The screen cylinder 11 achieves particle size separation through its inclined structure and multiple screen holes 12 on its surface. Quartz sand that meets the particle size requirements passes through the screen holes 12 and completes the initial separation. Large quartz sand particles that do not pass through the screen holes 12 slide naturally down the inclined direction of the screen cylinder 11 and enter the grinding cylinder 21 connected to the bottom of the screen cylinder 11. The support member 31 is connected to the grinding mechanism 2 and forms a stable support for it. After the grinding component 22, which is rotated in the grinding cylinder 21, is started, it grinds the large quartz sand inside. After grinding is completed, the telescopic member 32 connected to the upper end of the screen cylinder 11 extends and retracts, changing the inclination angle of the screen cylinder 11, so that the ground quartz sand in the grinding cylinder 21 flows back into the screen cylinder 11 and is screened again through the screen holes 12, thus completing the intelligent sorting of quartz sand.

[0029] In some embodiments, the intelligent quartz sand sorting machine further includes a dust suppression mechanism 4, which includes a dust suppression pipe 41 coaxially arranged with the grinding element 22. The dust suppression pipe 41 has a plurality of dust suppression holes 42, and a connecting sleeve 43 is rotatably provided at one end of the dust suppression pipe 41. The connecting sleeve 43 is connected to the dust collection device.

[0030] The intelligent quartz sand sorting machine of this invention expands the dust adsorption coverage area through the multi-point distribution design of dust suppression holes, ensuring that the fine dust generated during grinding and the dust generated during screening can be effectively captured, avoiding dust dispersion that may harm the health of operators; the connection structure between the connecting sleeve and the dust collection equipment enables centralized collection and treatment of dust; and the design of the dust suppression pipe rotating synchronously with the grinding parts eliminates the need for an additional driving device to achieve dynamic dust adsorption, simplifying the equipment structure while ensuring continuous dust suppression throughout the process and improving the cleanliness of the sorting process.

[0031] Specifically, when the grinding part 22 rotates, the dust suppression pipe 41, which is coaxially arranged with the grinding part 22, rotates synchronously. Multiple dust suppression holes 42 opened on the dust suppression pipe 41 form a negative pressure adsorption channel. The connecting sleeve 43 rotatably connected to one end of the dust suppression pipe 41 remains in a fixed communication state. An airflow passage is established with the external dust collection equipment through the connecting sleeve 43. The dust generated during the screening process of the screening mechanism 1 and the grinding process of the grinding mechanism 2 is sucked into the dust suppression pipe 41 through the dust suppression holes 42, and then transported to the dust collection equipment through the connecting sleeve 43 to achieve centralized collection and treatment of dust.

[0032] In some embodiments, the dust suppression mechanism 4 further includes a plurality of stirring rods 44 disposed on the dust suppression pipe 41, the stirring rods 44 being used to stir the quartz sand in the screen cylinder 11.

[0033] The intelligent quartz sand separator of this invention breaks up the accumulation of quartz sand in the screen cylinder through the rotation and stirring action of the stirring rod, allowing the quartz sand particles to be fully dispersed. This makes it easier for quartz sand that meets the particle size requirements to pass through the screen holes, improving screening efficiency and accuracy. The design of the stirring rod rotating synchronously with the dust suppression pipe utilizes existing driving power to achieve the stirring action, eliminating the need for additional stirring drive components, simplifying the overall structure of the equipment, and reducing manufacturing and maintenance costs. The stirring rod's agitation of the quartz sand makes the dust generated during screening more easily suspended and adsorbed by the surrounding dust suppression holes, improving the dust capture efficiency of the dust suppression mechanism and further reducing dust diffusion and dust adhesion to equipment components. The stirring action of the stirring rod avoids the problem of large-particle quartz sand accumulating locally in the screen cylinder, preventing it from sliding off smoothly, ensuring that large-particle quartz sand enters the grinding cylinder stably for grinding, and improving the smooth connection between screening and grinding processes.

[0034] Specifically, the rotation of the grinding part 22 drives the coaxial dust suppression pipe 41 to rotate. When the dust suppression pipe 41 rotates, it synchronously drives the multiple stirring rods 44 set on it to rotate. The rotating stirring rods 44 continuously stir the quartz sand in the screen cylinder 11, so that the quartz sand in the screen cylinder 11 is in a state of agitation and dispersion. At the same time, the dust suppression holes 42 on the dust suppression pipe 41 cooperate with the connecting sleeve 43 to connect with the dust collection equipment to complete the dust adsorption and collection.

[0035] In some embodiments, the screening mechanism 1 further includes a material cylinder 13 with one end open, the material cylinder 13 being connected to the screen cylinder 11, and a feed hole 14 being provided on the circumferential side of the material cylinder 13 for adding quartz sand into the screen cylinder 11. A sealing cover 15 is detachably connected to the feed hole 14.

[0036] The intelligent quartz sand separator of this invention provides a dedicated channel for quartz sand feeding through the interconnected design of the feed cylinder and screen cylinder. This allows the quartz sand to enter the screen cylinder smoothly and directionally, preventing material scattering during feeding and improving the regularity and utilization rate of the material feed. The structure design of the feed hole on the circumference of the feed cylinder adapts to the overall installation and operating space of the equipment, facilitating side feeding operations for operators, reducing the difficulty of feeding operations, and improving operational convenience. The detachable connection between the sealing cover and the feed hole ensures sealing of the feed hole during equipment operation, preventing quartz sand particles from splashing out and causing material waste, while also preventing dust generated during screening from spreading outwards, optimizing the working environment. The detachable structure of the sealing cover facilitates subsequent cleaning, inspection, and maintenance of the feed hole and the inside of the feed cylinder, reducing the difficulty of daily maintenance and extending the service life of the equipment.

[0037] Specifically, the operator opens the sealing cover on the feed hole 14 and feeds the quartz sand to be sorted into the feed hole 14 on the circumferential side of the material cylinder 13. The quartz sand enters the screen cylinder 11 through the material cylinder 13 for particle size screening. After feeding is completed, the sealing cover is detachably connected to the feed hole 14 to seal the feed hole 14 and prevent quartz sand from splashing out of the feed hole 14 and dust from spreading from the feed hole 14 during the screening process.

[0038] In some embodiments, the screening mechanism 1 further includes a discharge port 16, which is located at one end of the material cylinder 13 away from the screen cylinder 11. The discharge port 16 is used to discharge the material that has not been ground by the grinding mechanism 2, and a plug 17 is detachably connected to the discharge port 16.

[0039] The intelligent quartz sand separator of this invention, through its specially designed discharge port, achieves centralized collection and directional discharge of unground materials after grinding, preventing the accumulation of such materials inside the equipment and causing blockages in the screen cylinder and grinding cylinder, thus ensuring smooth operation of the screening and grinding processes. The detachable connection between the plug and the discharge port ensures reliable sealing of the discharge port during normal operation, preventing leakage of quartz sand raw materials or screened finished products from the discharge port, reducing material waste and improving raw material utilization. The detachable plug design allows for the removal of unground materials simply by removing the plug, eliminating the need to disassemble other parts of the equipment, simplifying cleaning and maintenance operations, and reducing the workload and difficulty of daily maintenance. The timely discharge of unground materials prevents them from repeatedly participating in grinding and screening inside the equipment, reducing ineffective wear on grinding parts and screen cylinders, extending the service life of core components, and lowering maintenance and replacement costs.

[0040] Specifically, during the screening process in the screen cylinder 11, materials that do not pass through the screen holes 12 and still do not meet the particle size requirements after being ground by the grinding mechanism 2 enter the material cylinder 13 with the material return process, and finally converge at the discharge port 16 at the end of the material cylinder 13 away from the screen cylinder 11. During normal sorting operation, the plug can be detachably connected to the discharge port 16 to achieve sealing and prevent material leakage from the discharge port 16. When it is necessary to clean up the unground material, the plug on the discharge port 16 can be removed to discharge the unground material in the material cylinder 13 from the discharge port 16.

[0041] In some embodiments, the screening mechanism 1 further includes a rotary motor 18, the output end of which is connected to the material cylinder 13. The rotary motor 18 is used to drive the screen cylinder 11 to rotate and is connected to the telescopic member 32.

[0042] The intelligent quartz sand separator of this invention uses a rotating motor to directly drive the material cylinder, which in turn drives the screen cylinder to rotate. This causes the quartz sand inside the screen cylinder to actively tumble, resulting in more thorough and uniform contact between the quartz sand particles and the screen openings, significantly improving screening efficiency and particle size separation accuracy. The connection design between the rotating motor and the telescopic component allows the telescopic component to simultaneously adjust the position of the rotating motor when adjusting the screen cylinder's tilt angle, ensuring the stability of the screen cylinder's rotation drive and achieving coordinated operation of angle adjustment and rotational screening. The motor-driven mechanized rotational screening replaces the passive screening method where quartz sand relies solely on its own gravity to slide down, accelerating the sliding speed of large-particle quartz sand towards the grinding cylinder and improving the efficiency of the screening and grinding processes. The rotating motor provides stable and continuous rotational power to the screen cylinder, reducing the probability of quartz sand accumulation and jamming inside the screen cylinder, ensuring the continuity of screening operations, and reducing equipment downtime due to material accumulation.

[0043] Specifically, the rotating motor 18 is connected to the telescopic component 32. The telescopic component 32 provides support for the rotating motor 18 and can adjust the position of the rotating motor 18 by its own extension and retraction. After the rotating motor 18 is started, its output end transmits power to the material cylinder 13 connected to it. The material cylinder 13 is driven to drive the connected screen cylinder 11 to rotate synchronously. The rotating screen cylinder 11 causes the quartz sand inside to make circumferential motion with the cylinder and continuously tumble. During the tumbling process, the quartz sand fully contacts the screen holes 12 to complete the particle size separation operation.

[0044] In some embodiments, the grinding element 22 includes a grinding seat 221, the end of the grinding seat 221 near the sieve cylinder 11 is a frustoconical section, the end of the grinding seat 221 away from the sieve cylinder 11 is a cylindrical section, and a plurality of grinding blocks 222 are provided on the grinding seat 221.

[0045] The intelligent quartz sand separator of this invention uses the conical section structure of the grinding seat to precisely guide large-particle quartz sand, preventing it from accumulating or getting stuck at the inlet of the grinding cylinder and ensuring smooth feeding. The multiple grinding blocks on the grinding seat work in conjunction with the inner wall of the grinding cylinder to increase the contact area between the grinding blocks and the large-particle quartz sand, improving grinding force and efficiency, and accelerating the grinding speed of the large-particle quartz sand. The cylindrical section of the grinding seat provides stable support for the grinding blocks, preventing them from falling off or shifting during high-speed grinding, ensuring the stability of the grinding operation and the consistency of the grinding effect. The segmented structure design of the conical and cylindrical sections of the grinding seat adapts to the material movement trajectory within the grinding cylinder, enabling the quartz sand to form an orderly grinding motion during the grinding process, reducing the amount of insufficiently ground quartz sand remaining.

[0046] Specifically, the grinding seat 221 of the grinding component 22 rotates under the drive of the grinding mechanism 2. The conical section of the grinding seat 221 near the screen cylinder 11 guides the large-particle quartz sand sliding down from the screen cylinder 11, allowing the large-particle quartz sand to smoothly enter the grinding gap between the grinding seat 221 and the grinding cylinder 21. Multiple grinding blocks 222 set on the grinding seat 221 rotate synchronously with the grinding seat 221 and cooperate with the inner wall of the grinding cylinder 21 to squeeze and grind the large-particle quartz sand in the grinding gap. The cylindrical section of the grinding seat 221 provides a stable mounting base for the grinding blocks 222, ensuring the continuous grinding action.

[0047] In some embodiments, the grinding element 22 further includes a rotating shaft 223, a grinding seat 221 is fixedly sleeved on the rotating shaft 223, the rotating shaft 223 extends out of the grinding cylinder 21, the extended end of the rotating shaft 223 is sleeved with a driven gear 224, the grinding cylinder 21 is provided with a driving gear 225, and the driving gear 225 is connected to the output end of the drive motor 226.

[0048] The intelligent quartz sand separator of this invention provides stable and precise rotational power to the grinding parts through gear meshing, ensuring uniform and controllable rotational speed, improving the consistency of grinding effect, and avoiding insufficient grinding caused by inconsistent grinding force. The external drive design, combining a drive motor with gear transmission, isolates the drive components from the grinding area inside the grinding cylinder, reducing wear and contamination from grinding dust and extending the service life of the drive components. The fixed sleeve structure between the rotating shaft and the grinding seat achieves efficient power transmission, allowing the grinding seat to obtain sufficient grinding torque, enabling the grinding of large-particle quartz sand of varying hardness and improving the equipment's adaptability. The gear transmission mechanical structure features high transmission efficiency and low failure rate, reducing the daily maintenance workload of the grinding drive system and lowering equipment maintenance costs.

[0049] Specifically, after the drive motor 226 starts, its output end drives the drive gear 225 to rotate. The drive gear 225 meshes with the driven gear 224 to transmit power to the driven gear 224. The driven gear 224 drives the sleeved rotating shaft 223 to rotate synchronously. The rotating shaft 223 drives the fixedly sleeved grinding seat 221 to rotate. The grinding seat 221 drives the grinding block 222 on it to perform circumferential grinding motion, completing the grinding operation on the large-particle quartz sand in the grinding cylinder 21. The rotating shaft 223 extends out of the structure of the grinding cylinder 21, providing installation and transmission space for the gear transmission assembly.

[0050] In some embodiments, the support member 31 includes a sliding sleeve 311 sleeved on the grinding cylinder 21, two support rods 312 rotatably connected to the sliding sleeve 311, and a support plate 313 fixedly connected to the bottom end of the two support rods 312; the telescopic member 32 includes a support sleeve 321 sleeved on the rotating motor 18, two telescopic rods 322 rotatably connected to the support sleeve 321, and a connecting plate 323 fixedly connected to the bottom end of the two telescopic rods 322; a receiving hopper 19 is provided on the lower side of the screen cylinder 11.

[0051] The intelligent quartz sand separator of this invention features a rotating connection design between a sliding sleeve and a support rod. This design allows the support to adapt to slight positional changes in the grinding cylinder, while providing stable support for the grinding mechanism, ensuring its stability during operation and reducing vibration and deviation. The synchronous extension and retraction of two telescopic rods adjusts the tilt angle of the screen cylinder, making angle adjustment smoother and more precise, avoiding imbalance caused by single-rod adjustment and improving the reliability of angle adjustment. A dedicated receiving hopper collects the screened qualified quartz sand centrally, preventing material waste caused by scattering and facilitating subsequent unified transportation and storage of the qualified quartz sand. The support sleeve supporting the rotating motor reduces radial vibration during operation, ensuring the motor's operational stability and extending its service life. The bottom support design of the support plate and connecting plate increases the contact area between the support and telescopic components and the ground, reducing the pressure of the equipment on the ground and preventing positional deviation due to gravity settlement, thus ensuring the overall stability of the equipment.

[0052] Specifically, the sliding sleeve 311 of the support member 31 is fitted onto the grinding cylinder 21, which can accommodate slight positional adjustments of the grinding cylinder 21. The two support rods 312 rotatably connected to the sliding sleeve 311 form a stable triangular support for the sliding sleeve 311. The support rods 312 transfer the weight of the grinding mechanism 2 to the support plate 313 at the bottom, thus achieving stable support for the grinding mechanism 2. The support sleeve 321 of the telescopic member 32 is fitted onto the rotating motor 18, providing radial support for the rotating motor 18. The two telescopic rods 322 rotatably connected to the support sleeve 321 adjust their length by telescopically extending and retracting, thereby driving the support sleeve 321 and the rotating motor 18 to rise and fall, thereby changing the tilt angle of the screen cylinder 11. The weight of the telescopic rods 322 is transferred to the connecting plate 323 at the bottom. The receiving hopper 19 on the lower side of the screen cylinder 11 collects the qualified particle size quartz sand that passes through the screen holes 12.

[0053] The intelligent quartz sand sorting method of this invention, utilizing the intelligent quartz sand sorting device of any of the above embodiments, includes the following steps: Initial screening process: The quartz sand to be sorted is fed into the upper opening of the screen cylinder. Multiple screen holes on the screen cylinder are used to sort the quartz sand by particle size. The quartz sand that meets the particle size requirements passes through the screen holes and is sorted. The large-sized quartz sand that does not pass through the screen holes slides down the inclined screen cylinder into the grinding cylinder of the grinding mechanism connected to the bottom of the screen cylinder. Large particle size grinding process: Start the rotating grinding element inside the grinding cylinder to grind the large particle size quartz sand that has entered the grinding cylinder until the large particle size quartz sand reaches the preset grinding particle size; Secondary screening process: By changing the inclination angle of the screen cylinder through the telescopic component, the quartz sand ground in the grinding cylinder flows back to the screen cylinder and is screened again through the screen holes, thus completing the intelligent sorting of quartz sand.

[0054] The intelligent quartz sand sorting method of this invention, through the pre-treatment of initial screening, first completes the rapid sorting of qualified quartz sand particles, reducing the processing volume of subsequent grinding processes and improving the overall sorting efficiency; through the grinding treatment with preset grinding particle size, large-particle quartz sand is specifically ground to ensure that the particle size of the ground quartz sand is more in line with application requirements, thus improving product quality; through the post-verification of secondary screening, the particle size of the ground material is strictly re-inspected, effectively removing large particles that do not meet the standards, ensuring the particle size uniformity and consistency of the final product; through the standardized process design of "screening-grinding-secondary screening", the quartz sand sorting is automated and closed-loop, eliminating the need for manual intervention in the connection of each process, reducing labor costs, and improving the standardization of sorting processing.

[0055] Specifically, the process begins with an initial screening process. The quartz sand to be sorted is fed into the upper opening of the screen cylinder 11, and particle size is separated using multiple screen holes 12 on the screen cylinder 11. Qualified quartz sand passes through the screen holes 12 and is sorted, while larger particles slide into the grinding cylinder 21. Next, a large-particle grinding process is performed. The grinding element 22 inside the grinding cylinder 21 is activated to grind the large particles of quartz sand to the preset particle size. Finally, a secondary screening process is performed. The tilt angle of the screen cylinder 11 is changed by the telescopic element 32, allowing the ground quartz sand to flow back into the screen cylinder 11 and be screened again through the screen holes 12, thus completing the entire intelligent quartz sand sorting process.
