[0002] Silicon material is the basic raw material at the very upstream of the solar photovoltaic industry chain. It is essentially high-purity polycrystalline silicon obtained through purification. In order to process silicon material into monocrystalline silicon rods or polycrystalline silicon ingots for manufacturing silicon wafers and to ensure the uniformity of its chemical purity and particle size, silicon material screening spiral propulsion particle sorting equipment is required.

[0003] The silicon material screening spiral propulsion particle sorting equipment is a device that uses the rotation of spiral blades to propel silicon material particles forward in the cylinder and achieve automatic grading and screening according to size. Traditional equipment has the problem that silicon material is prone to agglomeration and compaction during spiral propulsion, resulting in low screening efficiency and poor sorting accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a silicon material screening spiral propulsion particle sorting device, which aims to improve the problem of silicon material easily agglomerating and compacting during spiral propulsion.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicon material screening spiral propulsion particle sorting device, comprising a base plate, a buffer assembly provided on the upper surface of the base plate, a support plate fixedly connected to the bottom end of the buffer assembly, a motor fixedly connected to the upper surface of the base plate, a connecting shaft fixedly provided at the output end of the motor, an eccentric disk fixedly connected to the outer wall of the connecting shaft, a connecting rod fixedly connected to the outer wall of the eccentric disk, a convex cylinder rotatably connected to the outer wall of the connecting rod, a circular block slidably connected inside the convex cylinder, a fixing column fixedly connected to the upper surface of the circular block, the outer wall of the fixing column slidably connected through the interior of the convex cylinder, a spring second provided on the outer wall of the fixing column, one end of the spring second fixedly connected to the upper surface of the circular block, and the other end fixedly connected to the inner top wall of the convex cylinder, a cylinder slidably connected to the outer wall of the convex cylinder, and the bottom ends of the fixing column and the cylinder both fixedly connected to the lower surface of the support plate.

[0006] Preferably, the buffer assembly includes a telescopic leg, the bottom end of which is fixedly connected to the upper surface of the base plate, the top end of which is fixedly connected to the lower surface of the support plate, and a spring is provided inside the telescopic leg, the outer wall of which is slidably connected to the inner wall of the telescopic leg.

[0007] Preferably, a second motor, a gearbox, and a fixed cylinder are fixedly connected to the upper surface of the support plate, and a second connecting shaft is fixedly provided at the output end of the second motor.

[0008] Preferably, the outer wall of the second connecting shaft is rotatably connected through the inside of the gearbox, and the outer wall of the second connecting shaft is fixedly connected to the inside of the first gear.

[0009] Preferably, the tooth end of the first gear is meshed with the second gear, and the inside of the second gear is fixedly connected to a rotating shaft, the outer wall of which is rotatably connected through the inside of the gearbox.

[0010] Preferably, an auger blade is fixedly connected to the outer wall of the rotating shaft, and a screen cylinder is rotatably connected through the outer wall of the rotating shaft.

[0011] Preferably, the outer wall of the screen cylinder is fixedly connected to the inside of the fixed cylinder, and a feed valve is fixedly connected to the inside of the screen cylinder, with the outer wall of the feed valve fixedly connected to the inner wall of the fixed cylinder.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, a motor drives a connecting shaft to rotate, which in turn drives an eccentric disc to rotate, thereby causing a connecting rod to rotate inside a convex cylinder. This causes the convex cylinder to move up and down reciprocally inside the cylinder. The bottom of the convex cylinder impacts a circular block, which in turn causes the support plate to vibrate through a fixed column. This vibration of the sorting mechanism achieves the effect of loosening the silicon material and increasing the efficiency of silicon material screening.

[0015] 2. In this utility model, the connecting shaft is driven by motor two to rotate in the gearbox, which in turn drives the gear set to rotate, thereby causing the rotating shaft to rotate in the gearbox and the screen cylinder. The rotating shaft drives the auger blade to rotate to push the silicon material. The silicon material first passes through the first half of the screen cylinder. Smaller particles fall into the fixed cylinder through the screen holes and are discharged by discharge valve one. Larger particles continue to be pushed to the second half of the screen cylinder. Particles that meet the specifications are screened out and discharged by discharge valve two. The largest particles are finally pushed out and discharged by discharge valve three. This plays a role in grading and sorting silicon material, achieving the effect of meeting different production needs and improving screening efficiency. Attached Figure Description

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a silicon material screening spiral propulsion particle sorting device, including a base plate 1, a buffer assembly provided on the upper surface of the base plate 1, a support plate 13 fixedly connected to the bottom end of the buffer assembly, a motor 4 fixedly connected to the upper surface of the base plate 1, a connecting shaft 5 fixedly provided at the output end of the motor 4, an eccentric disk 6 fixedly connected to the outer wall of the connecting shaft 5, a connecting rod 7 fixedly connected to the outer wall of the eccentric disk 6, a convex cylinder 8 rotatably connected to the outer wall of the connecting rod 7, a circular block 9 slidably connected inside the convex cylinder 8, a fixing column 10 fixedly connected to the upper surface of the circular block 9, the outer wall of the fixing column 10 slidably connected through the interior of the convex cylinder 8, a spring 11 provided on the outer wall of the fixing column 10, one end of the spring 11 fixedly connected to the upper surface of the circular block 9, and the other end fixedly connected to the inner top wall of the convex cylinder 8, a cylinder 12 slidably connected to the outer wall of the convex cylinder 8, and the bottom ends of the fixing column 10 and the cylinder 12 are both fixedly connected to the lower surface of the support plate 13;

[0025] Specifically, a motor 4 is fixedly connected to the upper surface of the base plate 1, providing power for the vibration of the equipment and ensuring the stable operation of the vibration mechanism. This drives the connecting shaft 5 to rotate. The output end of the motor 4 is fixed to the connecting shaft 5, and an eccentric disk 6 is fixed to the outer wall of the connecting shaft 5. This drives the eccentric disk 6 to rotate, converting the rotational power of the motor into eccentric motion, thus providing driving force for the connecting rod 7. The eccentric disk 6 drives the connecting rod 7 to rotate inside the convex cylinder 8, converting the circular motion of the eccentric disk 6 into the reciprocating motion of the convex cylinder 8, thus driving the convex cylinder 8 to move. The connecting rod 7 drives the convex cylinder 8 to move up and down reciprocally inside the cylinder 12. The movement of the cylindrical cylinder 8 causes the bottom of the convex cylinder 8 to impact the circular block 9, transmitting vibration through the impact force to drive the fixed column 10. The fixed column 10 is fixed to the upper surface of the circular block 9, and the outer wall of the fixed column 10 is slidably connected to the convex cylinder 8. A second spring 11 is provided to cushion the impact force when the convex cylinder 8 impacts, while simultaneously driving the fixed column 10 to transmit vibration to the support plate 13, thus protecting the components and enhancing the vibration effect. The support plate 13 is fixedly connected to both the fixed column 10 and the bottom of the cylinder 12, thus driving the support plate 13 to vibrate. In turn, the support plate 13 drives the sorting mechanism to vibrate synchronously, achieving the effect of loosening the silicon material and increasing the chance of passing through the screen.

[0026] Reference Figure 1 and Figure 3 The buffer assembly includes a telescopic leg 2, the bottom end of which is fixedly connected to the upper surface of the base plate 1, and the top end of which is fixedly connected to the lower surface of the support plate 13. A spring 3 is provided inside the telescopic leg 2, and the outer wall of the spring 3 is slidably connected to the inner wall of the telescopic leg 2.

[0027] Specifically, a buffer assembly is installed on the upper surface of the base plate 1. The bottom end of the telescopic leg 2 is fixedly connected to the base plate 1, and the top end is connected to the support plate 13. A spring 3 is installed inside the buffer assembly to provide elastic support for the support plate 13. The spring 3 extends and retracts with the vibration of the support plate 13 to achieve the initial effect of buffering vibration impact. During vibration, the support plate 13 drives the telescopic leg 2 to extend and retract, and the spring 3 to stretch and compress, which further buffers the vibration impact, reduces the vibration damage to the main body of the equipment, and achieves the effect of stabilizing the equipment and extending its service life. The cylindrical cylinder 12 is slidably connected to the convex cylinder 8 to limit the movement direction of the convex cylinder 8, prevent its deviation from causing vibration instability, and ensure the accuracy of the vibration trajectory.

[0028] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The upper surface of the support plate 13 is fixedly connected to a second motor 14, a gearbox 18, and a fixed cylinder 21. The output end of the second motor 14 is fixedly provided with a second connecting shaft 15. The outer wall of the second connecting shaft 15 is rotatably connected through the inside of the gearbox 18, and the outer wall of the second connecting shaft 15 is fixedly connected to the inside of a first gear 16. The tooth ends of the first gear 16 are meshed with a second gear 17, and the inside of the second gear 17 is fixedly connected to a rotating shaft 19. The outer wall of the rotating shaft 19 is rotatably connected through the inside of the gearbox 18.

[0029] Specifically, a second motor 14 is fixedly connected to the upper surface of the support plate 13, providing power for silicon material sorting and ensuring stable operation of the subsequent mechanism, thereby driving the second connecting shaft 15 to rotate. The second connecting shaft 15 is fixedly mounted at the output end of the second motor 14, and its outer wall is rotatably connected to the inside of the gearbox 18, where a first gear 16 is fixedly connected. This drives the first gear 16 to rotate within the gearbox 18, transmitting the motor power to the gear transmission system to provide driving force for the sorting mechanism. The teeth of the first gear 16 mesh with the second gear 17, driving the second gear 17 to rotate. Gear meshing changes the direction and speed of power transmission, adapting to the operating requirements of the rotating shaft 19. Gear 2 17 is internally fixedly connected to a rotating shaft 19, and the outer wall of the rotating shaft 19 is rotatably connected to the inside of the gearbox 18 and the screen cylinder 22. This serves to drive the rotating shaft 19 to rotate synchronously, transmitting gear power to the auger blade 20 to drive the silicon material forward. The auger blade 20 is fixedly connected to the outer wall of the rotating shaft 19, which propels the silicon material to move within the screen cylinder 22 as the rotating shaft 19 rotates, ensuring that the silicon material passes evenly through different screening areas of the screen cylinder 22 and achieving a comprehensive sorting effect. The feed valve 23 is fixedly connected to the inside of the fixed cylinder 21 through the outer wall of the screen cylinder 22 and is fixed inside the screen cylinder 22. This provides a screening channel for the silicon material and controls the amount of silicon material entering, achieving precise control of the feed.

[0030] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A screw conveyor blade 20 is fixedly connected to the outer wall of the rotating shaft 19, and a screen cylinder 22 is rotatably connected through the outer wall of the rotating shaft 19; the outer wall of the screen cylinder 22 is fixedly connected through the inside of the fixed cylinder 21, and a feed valve 23 is fixedly connected to the outer wall of the screen cylinder 22, with the outer wall of the feed valve 23 fixedly connected to the inner wall of the fixed cylinder 21; a discharge valve 1 24 and a discharge valve 25 are fixedly connected through the inside of the fixed cylinder 21, and a feed valve 23 and a discharge valve 3 26 are fixedly connected through the inside of the screen cylinder 22;

[0031] Specifically, different aperture sizes are set in different sections of the screen cylinder 22 to allow silicon materials of different sizes to pass through the screen in a graded manner: the screen holes in the first half separate smaller silicon materials, and the screen holes in the second half separate larger silicon materials, achieving the effect of grading and sorting. The fixed cylinder 21 has two fixed discharge valves, 24 and 25, which are respectively located below the screen holes in the first and second halves of the screen cylinder 22, facilitating the discharge of silicon materials of different specifications and controlling the discharge timing to achieve the effect of orderly collection and sorting of products. The fixed discharge valve 26 has three fixed discharge valves, which discharge larger silicon materials that have not passed through the screen, completing the full-size sorting process and achieving the effect of comprehensively separating silicon materials of different sizes. Finally, through the coordinated action of these mechanisms, the silicon materials are accurately sorted by size, improving silicon material purity, meeting different production needs, and increasing the efficiency of subsequent processing.

[0032] Working principle: When the equipment is needed, first open the feed valve 23 to put the silicon material into the screen cylinder 22. At the same time, start the motor 14. The motor 14 drives the connecting shaft 15 to rotate inside the gearbox 18, which in turn drives the gear 16 to rotate. The gear 16 drives the gear 17 to rotate, which in turn drives the rotating shaft 19 to rotate inside the gearbox 18 and the screen cylinder 22 respectively. The rotating shaft 19 drives the auger blade 20 to rotate, thus pushing the silicon material. When the silicon material passes through the first half of the screen cylinder 22, the smaller silicon material falls into the fixed cylinder 21 through the screen holes. Open the discharge valve 24 to discharge it. The larger or larger silicon material continues to be pushed until it reaches the second half of the screen cylinder 22. The larger silicon material falls into the fixed cylinder 21 through the screen holes. Open the discharge valve 25 to discharge it. Open the discharge valve 26, and the larger silicon material is pushed out by the auger blade 20. This sorts the silicon material by size and meets different production needs.

[0033] Simultaneously, motor 4 is started, which, under the connection of connecting shaft 5, drives eccentric disc 6 to rotate. Eccentric disc 6 drives connecting rod 7 to rotate inside convex cylinder 8. Connecting rod 7 drives convex cylinder 8 to reciprocate up and down inside cylinder 12. The bottom of convex cylinder 8 impacts circular block 9, which, under the connection of fixed column 10, drives support plate 13 to vibrate. Support plate 13 then drives the sorting mechanism to vibrate, achieving the effect of loosening silicon material and increasing the chance of passing through the screen. During the impact, spring 11 acts as a buffer. During the vibration, support plate 13 drives telescopic leg 2 and spring 3 to extend and retract and stretch respectively, thus achieving a buffering effect, stabilizing the main body of the equipment, reducing impact, and extending service life.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
