Description

Technical Field

[0001] This utility model relates to the field of high-purity silicon material screening technology, specifically to a high-purity silicon material impurity separation and screening mechanism. Background Technology

[0002] High-purity silicon is a core raw material in high-tech fields such as photovoltaics and semiconductors. During the silicon processing, some waste material and cleaning equipment waste are generated. Because the silicon particle size is less than 10mm, this waste material easily mixes with impurities when it comes into contact with equipment and the ground. The waste material contains non-silicon impurities such as PP fragments, wood chips, paper scraps, lint, plastic fragments, and metal shavings, resulting in slight impurities mixed in with the original high-purity silicon material. This type of recycled silicon material cannot be directly recycled and requires workers to concentrate intensely on sorting it. Not only is the production capacity low, but this sorting method is also greatly affected by human factors. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a high-purity silicon material impurity separation and screening mechanism. This mechanism analyzes light impurities in high-purity silicon materials. Light non-silicon impurities such as PP fragments, wood chips, paper scraps, lint, plastic fragments, and nylon mesh fibers have an overall weight lower than the silicon material itself and can be suspended and removed by buoyancy and rinsing using water. Metal shavings and other impurities can be removed by adsorption using strong magnets during the processing, significantly improving screening efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A high-purity silicon material impurity separation and screening mechanism includes a water shaking table, a support platform, a drive motor, a connecting rod, a first water outlet pipe, a second water outlet pipe, a guide pipe, a spray head, a wastewater tank, and a material tank. The water shaking table has a feed inlet and a water inlet on one side. A guide pipe is installed between the feed inlet and the water inlet. The guide pipe has one or more water outlet holes arranged along its body, with water exiting from the outlet holes towards the other side of the water shaking table. A wastewater tank is located below the other side of the water shaking table. The water inlet end of the guide pipe is connected to the first water outlet pipe. A support platform is mounted above the drive end of the water shaking table, and the water shaking table swings from the drive end towards the opposite end. A material tank is located below the opposite end. A first drive motor is fixed to the inner side of the support platform; the drive end of the first drive motor is connected to the body of the second water outlet pipe through a connecting rod, and the drive motor drives the water outlet end of the second water outlet pipe to shake in the direction of motor rotation; a spray head is installed at the water outlet end of the second water outlet pipe; the spray head sprays water towards the surface of the water shaking table.

[0005] Preferably, a hopper is installed inside the material box; the material box and the wastewater box are respectively connected to a sewage tank through water pipes.

[0006] Preferably, a bracket is fixed to the top of the support platform; a top plate is fixed between the brackets; and the second water outlet pipe passes through the top plate and connects to the water source.

[0007] Preferably, a magnetic suction device is mounted above the material box; the magnetic suction device includes a frame and a magnet; the magnet is installed in the mounting groove of the frame.

[0008] Preferably, an iron collecting groove is fixed on the outside of the material box; both ends of the magnetic suction component are movably connected to the adjusting frame; the adjusting frame is movably inserted into the adjusting slot seat; one end of the magnetic suction component is connected to the driving end of the second drive motor, and the second drive motor adjusts the angle of the magnetic suction component; the adjusting slot seat has one or more threaded holes, and screws are installed in the threaded holes to press the adjusting frame.

[0009] Preferably, the bottom of the adjusting slot seat is provided with a sliding groove, which cooperates with the slide rail; the adjusting slot seat is connected to the telescopic end of the cylinder, and the cylinder drives the adjusting slot seat to move above the material box and the iron collection trough.

[0010] Preferably, a lifting frame is fixed at the top of the end of the iron collecting trough; a lead screw is rotatably mounted on the lifting frame; one end of the lead screw is connected to the drive end of the third drive motor; guide rods are fixed on both sides of the lead screw; a lifting plate is movably mounted on the guide rods; a screw hole is provided in the middle of the lifting plate to cooperate with the lead screw; a scraper is fixed on the side of the lifting plate corresponding to the magnetic suction component.

[0011] The beneficial effects of this utility model are: 1. The water flow direction is determined by the guide pipe, controlling the water flow from one side of the water shaker to the other. The buoyancy of the water suspends and washes away light non-silicon impurities. The spray head agitates the water flow on the shaker, causing the silicon material to move to one side, thus prolonging its time on the shaker and facilitating the removal of light non-silicon impurities. 2. As the silicon material exits from one end of the shaker, it passes through a magnetic suction device. Iron impurities in the silicon material are adsorbed above the magnetic device, filtering out these impurities. The magnetic device is periodically cleaned by a scraper, and the removed iron is stored in an iron collection tank. This method effectively filters impurities from the silicon material, improving screening efficiency and making it more suitable for silicon material screening operations in this industry.

Detailed Implementation

[0017] like Figure 1-3 As shown, to achieve the above objectives, this utility model employs the following technical solution: A high-purity silicon material impurity separation and screening mechanism is disclosed, which is an improvement upon the existing water shaking table 1. The water shaking table 1 includes a bed surface and a drive structure for driving the bed surface. A feed inlet 1.1 and a water inlet 1.2 are respectively provided on one side of the water shaking table 1, with the water inlet 1.2 replaced by a guide pipe 7. The water shaking table 1 is existing equipment and will not be described in detail. The main improvement lies in the installation of the guide pipe 7 between the feed inlet 1.1 and the water inlet 1.2. The guide pipe 7 has one or more water outlet holes 7.1 arranged along its body, with water outlet holes 7.1 discharging water towards the other side of the water shaking table 1. A wastewater tank 9 is located below the other side of the water shaking table 1, and water containing light impurities enters the wastewater tank 9 along the bed surface. One end of the guide pipe 7 is connected to the first outlet pipe 5; a support platform 2 is mounted above the drive end of the water shaker 1, and the water shaker 1 swings from the drive end toward the opposite end, with a material box 10 located below the opposite end; the silicon material moves toward the material box 10 following the swing of the bed surface. A bracket 2.1 is fixed to the top of the support platform 2; a top plate 2.2 is fixed between the brackets 2.1; the second outlet pipe 6 passes through the top plate 2.2 and connects to the water source.

[0018] like Figure 1-3As shown, a first drive motor 3 is fixed to the inner side of the support platform 2; the drive end of the drive motor is connected to the body of the second water outlet pipe 6 via a connecting rod 4, and the drive motor drives the water outlet end of the second water outlet pipe 6 to shake in the direction of motor rotation; a spray head 8 is installed at the water outlet end of the second water outlet pipe 6; the spray head 8 sprays water towards the surface of the water shaker 1; by shaking the spray head, the flow direction of the water on the water shaker 1 is disturbed to a certain extent, and when the silicon material moves to one side with the shaking of the water shaker 1, it plays a certain interference role, which can prolong the time of the silicon material in the water shaker 1, which is conducive to the thorough removal of light non-silicon impurities. In order to achieve this effect, the first water outlet pipe 5 and the second water outlet pipe 6 are made of PVC pipe, which has a certain deformation capacity. The first water outlet pipe 5 can shake with the shaker, and the second water outlet pipe 6 shakes with the first drive motor 3. A hopper 13 is installed inside the material box 10. After the silicon material is discharged from the water shaker 1, it falls into the hopper 13. The hopper 13 has a drain hole. Water enters the material box 10 and the silicon material stays in the hopper 13. The operator removes the hopper 13 periodically. The material box 10 and the wastewater tank 9 are respectively connected to the sewage tank through water pipes.

[0019] like Figure 1-3 As shown, to facilitate the removal of iron impurities from the silicon material, a magnetic suction component 14 is mounted above the material bin 10. The silicon material discharged from the shaker is influenced by the magnetic suction component 14. The magnetic suction component 14 includes a frame 14.1 and a magnet 14.2; the magnet 14.2 is installed in the mounting groove of the frame 14.1. An iron collection groove 11 is fixed to the outside of the material bin 10; both ends of the magnetic suction component 14 are movably connected to an adjusting frame 15; the adjusting frame 15 is movably inserted into an adjusting slot seat 16; the adjusting slot seat 16 has one or more threaded holes, and screws 12 are installed in the threaded holes to press the adjusting frame 15. One end of the magnetic suction component 14 is connected to the driving end of a second drive motor 17, and the second drive motor 17 adjusts the angle of the magnetic suction component 14. The bottom of the adjusting slot seat 16 is provided with a sliding groove 18, which cooperates with the slide rail 19. The adjusting slot seat 16 is connected to the telescopic end of the cylinder 20, and the cylinder 20 drives the adjusting slot seat 16 to move above the material box 10 and the iron collection trough 11. A lifting frame 21 is fixed at the top of the end of the iron collection trough 11. A lead screw 22 is rotatably provided on the lifting frame 21. One end of the lead screw 22 is connected to the drive end of the third drive motor 25. Guide rods 23 are fixed on both sides of the lead screw 22. A lifting plate 26 is movably sleeved on the guide rods 23. A screw hole is provided in the middle of the lifting plate 26 to cooperate with the lead screw 22. A scraper 24 is fixed on one side of the lifting plate 26 corresponding to the magnetic attractor 14. The scraper 24 scrapes away the iron-containing impurities on the magnet 14. The frame 14.1 of the magnetic attractor 14 does not contain magnetism, so the iron-containing impurities scraped away by the scraper 24 can easily detach when passing through the frame 14.1.

[0020] Workflow: Silicon material enters the water shaking table 1 from the feed inlet 1.1 through a shaking motion. Water is drained from the outlet through the guide pipe 7, causing water to flow from one side of the table to the other. The first drive motor 3 activates, causing the spray heads to shake. This moves the silicon material along the shaking direction of the water shaking table 1. Simultaneously, the water sprayed from the spray heads disrupts the regular movement of the silicon material, increasing its time on the water shaking table 1. Light non-silicon impurities enter the wastewater tank 9 along the water flow direction. Due to the movement of the silicon material along the water shaking table 1, they accumulate in the hopper 13 of the material bin 10. During the process of entering the material bin 10, iron-containing impurities are adsorbed onto the magnet 14.2 of the magnetic suction component 14. Magnet 14.2 needs to be cleaned regularly. During cleaning, first drive the second drive motor 17 to rotate the magnetic suction component 14 so that the magnet 14.2 of the magnetic suction component 14 faces the scraper 24. The cylinder 20 extends, causing the magnetic suction component 14 to move above the iron collection trough 11. At this time, the scraper 24 contacts the adsorption side of the magnetic suction component 14. The third drive motor 25 works, driving the scraper 24 to move down and scrape the iron-containing impurities on the magnet 14.2 until it moves to the frame 14.1. Since the frame 14.1 is not magnetic, the iron-containing impurities fall off and into the iron collection trough 11. After cleaning is completed, the magnetic suction component 14 is reset.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
