Description

Technical Field

[0001] This utility model relates to the field of quartz sand screening technology, and in particular to a multi-stage screening device for mining quartz sand. Background Technology

[0002] Quartz sand, as an important mineral resource, plays an indispensable role in many strategic emerging industries and traditional industrial fields such as semiconductors, photovoltaics, glass, ceramics, and chemicals due to its characteristics such as high temperature resistance, corrosion resistance, and high insulation. With the rapid development of various industries, the demand for high-purity quartz sand of different particle sizes continues to rise. In the process of quartz sand mining, sand screening is a key link to achieve quartz sand classification by particle size and ensure product quality.

[0003] Traditional sand screening devices have several problems in practical applications. On the one hand, most traditional equipment relies on a single vibration method or a simple screening structure, which cannot fully disperse quartz sand and allow it to pass through the screen quickly. This results in a large amount of quartz sand accumulating on the screen surface, prolonging the screening time and making it difficult to meet the production capacity requirements of large-scale mining operations. On the other hand, during the screening process, the impact force of quartz sand on the screen plate is relatively large. Conventional screen plates are prone to wear and deformation under long-term and frequent impacts, which significantly shortens the service life of the screen plates, increases equipment maintenance costs and downtime, and seriously affects the continuity of production. In addition, some traditional sand screening devices are not reasonably designed in terms of structure. The installation and disassembly of the screening plates are cumbersome, which brings great inconvenience to daily equipment inspection and maintenance and the replacement of screening plates according to different screening needs, thus reducing the overall production efficiency.

[0004] Therefore, it is necessary to provide a new method for mining quartz sand using a multi-stage sand screening device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-stage sand screening device for mining quartz sand.

[0006] The multi-stage sand screening device for quartz sand mining provided by this utility model includes: a base, fixed columns equidistantly connected to the top of the base, a vibrating plate installed on the top of the fixed columns, a screening frame fixedly connected to the top of the vibrating plate, baffles fixedly connected to both sides of the screening frame, a first screening plate for screening quartz sand installed on the top of the vibrating plate, the first screening plate being located inside the corresponding screening frame, a second screening plate for screening quartz sand installed on the top of the vibrating plate, the second screening plate being located inside the corresponding screening frame, a third screening plate for screening quartz sand installed on the top of the vibrating plate, the third screening plate being located inside the corresponding screening frame, guide plates equidistantly connected to the top of the base, a vibration component for driving the vibrating plate to vibrate installed on the top of the base, and limiting components for restricting the movement of the first screening plate, the second screening plate, and the third screening plate, as well as the corresponding screening frame, are all installed inside these components.

[0007] Preferably, the vibration assembly includes: a sliding column, a spring, and a vibration motor. The sliding column is slidably connected to the top of the fixed column, one end of the sliding column is fixedly connected to the vibration plate, the outer wall of the sliding column is fitted with a spring, one end of the spring is fixedly connected to the fixed column, the other end of the spring is fixedly connected to the vibration plate, and the vibration motor is fixedly connected to the bottom of the vibration plate.

[0008] Preferably, the limiting component includes: a threaded rod, an extrusion block, an insert rod, and a slider. An insertion port is provided on one side of the screening frame. Threaded rods are threadedly connected to one side of the first screening plate, the second screening plate, and the third screening plate. An extrusion block is fixedly connected to the outer wall of the threaded rod. Insert rods are slidably connected to one side of the first screening plate, the second screening plate, and the third screening plate. A slider is slidably connected to the side of the screening frame near the insert rod.

[0009] Preferably, each of the multiple sets of guide plates has a guide groove on one side, and the multiple sets of sliders slide within the corresponding guide groove.

[0010] Preferably, each of the multiple sets of baffles has an opening on the side near the socket, and the opening size is the same as the socket size.

[0011] Preferably, a guide plate is fixedly connected to one side of the guide plate, and the guide plate has an inverted V-shaped design.

[0012] Preferably, the sieve apertures of the first sieve plate, the second sieve plate, and the third sieve plate are arranged from small to large, and the heights of the first sieve plate, the second sieve plate, and the third sieve plate in the vertical direction are arranged from high to low.

[0013] Preferably, the top of the guide plate is designed to be inclined.

[0014] Compared with related technologies, the multi-stage sand screening device for mining quartz sand provided by this utility model has the following advantages:

[0015] Improve screening efficiency:

[0016] This device drives the vibrating plate to vibrate up and down through a vibration assembly. Simultaneously, the vibration of the screening frame drives the slider to slide within the guide groove of the guide plate, achieving lateral movement of the screening plate. This combined vertical and horizontal vibration mode allows the quartz sand to be fully dispersed, preventing accumulation. Furthermore, the first, second, and third screening plates are arranged according to the increasing sieve aperture and decreasing height, forming a multi-stage continuous screening process. Quartz sand can pass through each screening plate sequentially to complete the grading, significantly shortening the screening time and meeting the production capacity requirements of large-scale quartz sand mining.

[0017] Reduce sieve plate wear:

[0018] When the screening frame vibrates to its highest point, its top is flush with the top of the inclined surface of the guide plate. The quartz sand can slide along the inclined surface to the next screening plate, which significantly reduces the impact force caused by the height difference. At the same time, the combined vibration makes the quartz sand pass through the screen holes more smoothly, reducing hard collisions with the screen plate, extending the service life of the screen plate, and reducing the frequency of maintenance and replacement.

[0019] Improve equipment maintenance efficiency:

[0020] The limiting component of this device uses a threaded rod to drive the extrusion block to press the insertion rod, so that the insertion rod is inserted into the slider to fix the screening plate. To disassemble, simply rotate the threaded rod in the opposite direction to release the fixation. The operation is simple and convenient, and the screening plate with the corresponding screen hole can be quickly replaced according to different screening requirements, thereby improving the overall production efficiency.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 4 A multi-stage screening device for quartz sand mining includes: a base 1, with fixed columns 2 equidistantly fixed to the top of the base 1; a vibrating plate 3 mounted on the top of the fixed columns 2; a screening frame 4 fixedly connected to the top of the vibrating plate 3; baffles 5 fixedly connected to both sides of the screening frame 4; a first screening plate 6 for screening quartz sand mounted on the top of the vibrating plate 3, located inside the corresponding screening frame 4; a second screening plate 7 for screening quartz sand mounted on the top of the vibrating plate 3, located inside the corresponding screening frame 4; and a third screening plate 8 for screening quartz sand mounted on the top of the vibrating plate 3, located inside the corresponding screening frame 4. The base 1 is equidistantly fixed to the top of the vibrating plate 1. The base 1 has a guide plate 9 and a vibration assembly for driving the vibration plate 3 to vibrate. The first screening plate 6, the second screening plate 7, and the third screening plate 8, as well as the corresponding screening frame 4, are all equipped with limiting components to restrict the movement of the first screening plate 6, the second screening plate 7, and the third screening plate 8. Each of the multiple sets of baffles 5 has an opening 51 on the side near the insertion port. The size of the opening 51 is the same as the size of the insertion port. A guide plate 61 is fixedly connected to one side of the guide plate 9. The guide plate 61 has an inverted V-shaped design. The screen hole diameters of the first screening plate 6, the second screening plate 7, and the third screening plate 8 are arranged from small to large. The heights of the first screening plate 6, the second screening plate 7, and the third screening plate 8 in the vertical direction are arranged from high to low. The top of the guide plate 9 is inclined.

[0029] It should be noted that the baffles 5 on both sides of the screening frame 4 can prevent the quartz sand from spilling from the sides during vibration. The openings 51 on the baffles 5 are the same size as the insertion openings of the screening frame 4, so they do not affect the installation and disassembly of the screening plate. When the screening frame 4 vibrates to its highest point, the top of the screening frame 4 is flush with the top of the inclined surface of the guide plate 9. At this time, the quartz sand will slide from the inclined surface to the next screening plate, reducing the impact force of the quartz sand on the screening plate due to the height difference and increasing the service life of the screening plate.

[0030] Please see Figure 1 and Figure 2The vibration assembly includes: a sliding column 21, a spring 22 and a vibration motor 23. The sliding column 21 is slidably connected to the top of the fixed column 2. One end of the sliding column 21 is fixedly connected to the vibration plate 3. The outer wall of the sliding column 21 is fitted with a spring 22. One end of the spring 22 is fixedly connected to the fixed column 2 and the other end of the spring 22 is fixedly connected to the vibration plate 3. The vibration motor 23 is fixedly connected to the bottom of the vibration plate 3.

[0031] It should be noted that when the vibration motor 23 starts working, it drives the vibration plate 3 to vibrate. Since the top of the fixed column 2 is connected to the vibration plate 3 through the sliding column 21, and the outer wall of the sliding column 21 is fitted with a spring 22, when the vibration plate 3 vibrates, the sliding column 21 will slide inside the fixed column 2, and the spring 22 will extend and retract accordingly, providing elastic support for the vibration plate 3, so that the vibration plate 3 can vibrate up and down stably.

[0032] Please see Figures 1 to 4 The limiting components include: a threaded rod 31, an extrusion block 32, an insertion rod 33, and a slider 34. An insertion port is provided on one side of the screening frame 4. The threaded rod 31 is threadedly connected to one side of the first screening plate 6, the second screening plate 7, and the third screening plate 8. An extrusion block 32 is fixedly connected to the outer wall of the threaded rod 31. An insertion rod 33 is slidably connected to one side of the first screening plate 6, the second screening plate 7, and the third screening plate 8. A slider 34 is slidably connected to the side of the screening frame 4 near the insertion rod 33. A guide groove 41 is provided on one side of each of the multiple sets of guide plates 9. The sliders 34 slide within the corresponding guide grooves 41.

[0033] It should be noted that: when the threaded rod 31 is rotated, the threaded rod 31 drives the extrusion block 32 to move towards the insertion rod 33. The extrusion block 32 extrudes the insertion rod 33 so that it is inserted into the slider 34. At this time, the insertion rod 33 is restricted by the slider 34 and the extrusion block 32 and cannot slide freely. The movement of the slider 34 will drive the insertion rod 33 to perform corresponding movements.

[0034] The working principle of the multi-stage sand screening device for mining quartz sand provided by this utility model is as follows:

[0035] Screening plate installation:

[0036] Before the screening operation begins, the screening plates need to be fixed by the limiting components. The operator can place the first screening plate 6, the second screening plate 7, and the third screening plate 8 into the corresponding screening frame 4, and then rotate the threaded rod 31. The threaded rod 31 drives the extrusion block 32 to move towards the insertion rod 33. The extrusion block 32 extrudes the insertion rod 33 and inserts it into the slider 34, thereby limiting the movement of the first screening plate 6, the second screening plate 7, and the third screening plate 8 within the screening frame 4, ensuring that the screening plates are stable during the screening process. The screen apertures of the first screening plate 6, the second screening plate 7, and the third screening plate 8 are arranged from small to large, and their vertical height is arranged from high to low, preparing for multi-stage screening.

[0037] Screening operation:

[0038] During the screening operation, quartz sand is poured onto the first screening plate 6, and the vibration assembly is started. The vibration motor 23 begins to work, driving the vibrating plate 3 to vibrate. Since the top of the fixed column 2 is connected to the vibrating plate 3 through the sliding column 21, and the outer wall of the sliding column 21 is fitted with a spring 22, when the vibrating plate 3 vibrates, the sliding column 21 will slide inside the fixed column 2, and the spring 22 will extend and retract accordingly, providing elastic support for the vibrating plate 3, so that the vibrating plate 3 can vibrate stably up and down. The vibration of the vibrating plate 3 will drive the screening frame 4 to vibrate synchronously, thus completing the screening process. The first screening plate 6, the second screening plate 7, and the third screening plate 8 within frame 4 also vibrate. The quartz sand first comes into contact with the highest first screening plate 6. Because the sieve aperture of the first screening plate 6 is the smallest, only the quartz sand with extremely small particle size can pass through the sieve aperture and fall down. The remaining quartz sand moves to the second screening plate 7 below under the action of vibration. The sieve aperture of the second screening plate 7 is of medium size, which can screen out the quartz sand with medium particle size. Finally, the larger quartz sand moves to the third screening plate 8 and completes the final screening by passing through its larger sieve aperture.

[0039] Lateral vibration:

[0040] During the vibration of the screening frame 4, the screening frame 4 drives the slider 34 to vibrate up and down. Since the guide plate 9 has a guide groove 41 on one side, the slider 34 slides in the corresponding guide groove 41. The guide groove 41 guides the slider 34 to move laterally. The slider 34 then drives the insert rod 33 to move laterally. The multiple insert rods 33 then drive the first screening plate 6, the second screening plate 7 and the third screening plate 8 to move laterally. In this way, the screening plates can move laterally while vibrating up and down, which greatly improves the screening efficiency and effect. The quartz sand of different particle sizes after screening will fall into the guide plate 9 below. The guide plate 61 on one side of the guide plate 9 has an inverted V-shaped design, which can smoothly discharge the quartz sand from the device.

[0041] The baffles 5 on both sides of the screening frame 4 can prevent the quartz sand from spilling from the side during vibration. The openings 51 on the baffles 5 are the same size as the insertion openings of the screening frame 4, so they do not affect the installation and disassembly of the screening plate. When the screening frame 4 vibrates to the highest point, the top of the screening frame 4 is flush with the top of the inclined surface of the guide plate 9. At this time, the quartz sand will slide from the inclined surface to the next screening plate, reducing the impact force of the quartz sand on the screening plate due to the height difference and increasing the service life of the screening plate.
