Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. 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.

[0023] Referring to Figures 1-4, this utility model provides a technical solution:

[0024] A single-crystal silicon crushing production line includes a feeding device, a heating device, a water cooling device, and a drying device. The input end of the heating device is connected to the feeding device, which works in conjunction with the heating device. The water cooling device is installed between the output end of the heating device and the drying device. The feeding device adds single-crystal silicon to the heating device, where it is heated to a high temperature. Then, it enters the water cooling device for cooling, followed by drying in the drying device, and finally, it enters the crushing inlet at the output end of the drying device for crushing.

[0025] The feeding device includes a feeding box 1, fixed support bars 2, movable support bars 3, movable plate 4, dividing bars 5, and a conveying assembly. At least three fixed support bars 2 are fixedly installed on the top of the feeding box 1. Movable support bars 3 are provided between two adjacent fixed support bars 2. Movable support bars 3 are fixedly installed on the movable plate 4. The movable plate 4 is fixedly installed on the conveying assembly. The conveying assembly is located inside the feeding box 1. Dividing bars 5 are provided on both the fixed support bars 2 and the movable support bars 3. The feeding box 1 is fixedly connected to the heating furnace 14. A conveying assembly is installed inside the feeding box 1. A fixed support bar 2 is installed on the top of the feeding box 1. Movable support bars 3 are arranged alternately with the fixed support bars 2. The movable support bars 3 are fixed to the conveying assembly. The conveying assembly drives the movable plate 4 to move up and down, and also drives the movable plate 4 to move along the length of the fixed support bar 2. In the initial position, the upper surface of the movable support bar 3 is lower than the fixed support bar 2. Monocrystalline silicon is placed on the fixed support bar 2. When it is necessary to transport the monocrystalline silicon on the fixed support bar 2, the conveying assembly drives the movable support bar 3 to move upward. The dividing bar 5 on the movable support bar 3 contacts and lifts the monocrystalline silicon on the fixed support bar 2. Then, under the action of the conveying assembly, the monocrystalline silicon is moved towards the heating device side. After it moves into place, it moves downward and places the monocrystalline silicon on the transport cart 15, and then returns to the initial position. Both the fixed support bar 2 and the movable support bar 3 are provided with dividing bars 5. Under the action of dividing bars 5, the monocrystalline silicon will not come into contact with the fixed support bar 2 and the movable support bar 3, and the monocrystalline silicon will not be contaminated. The dividing bars 5 are detachably connected to the fixed support bar 2 and the movable support bar 3. The dividing bars 5 are monocrystalline silicon dividing bars.

[0026] In some embodiments, the conveying assembly includes a transverse guide rod 6, a movable frame 7, a feeding drive motor 8, a transmission screw 9, a lifting cylinder 10, and a vertical guide rod 11. At least two transverse guide rods 6 are fixedly installed inside the feeding box 1. The movable frame 7 is slidably installed on the transverse guide rods 6 and threadedly engaged with the transmission screw 9. Both ends of the transmission screw 9 are installed on the feeding box 1. The feeding drive motor 8 is fixedly installed on the feeding box 1 and is used to drive the transmission screw 9 to rotate. Lifting cylinders 10 are symmetrically arranged on both sides of the movable frame 7. Both ends of the movable plate 4 are fixedly connected to the piston rods on the two lifting cylinders 10 respectively. The movable plate 4 is fixedly connected to the upper end of the vertical guide rod 11. The lifting cylinder 10 is provided with a guide hole that engages with the vertical guide rod 11. The feeding box 1 has four parallel horizontal guide rods 6. The moving frame 7 is slidably mounted on the horizontal guide rods 6. The feeding drive motor 8 is a conventional motor. The feeding drive motor 8 drives the transmission screw 9 to rotate via chain drive. The transmission screw 9 drives the moving frame 7 to move. When the moving frame 7 moves, it drives the movable plate 4. The movable support bar 3 on the movable plate 4 carries the monocrystalline silicon along with it. The transmission screw 9 and the moving frame 7 are threaded together. The lifting cylinder 10 is a conventional cylinder. The lifting cylinder 10 drives the movable plate 4 to move up and down. The movable plate 4 drives the movable support bar 3 to move up and down. When the movable support bar 3 moves upward, its upper surface is higher than the upper surface of the fixed support bar 2. The monocrystalline silicon on the fixed support bar 2 falls onto the movable support bar 3 and then moves with the movable support bar 3 to the transport vehicle 15. The vertical guide rod 11 plays a stabilizing role for the up and down movement of the movable plate 4.

[0027] In some embodiments, a pusher rod 12 is fixedly mounted on the movable frame 7, and a pusher plate 13 is mounted on the pusher rod 12. The movable frame 7 moves along the transverse guide rod 6, carrying the pusher rod 12 with it. There are two pusher rods 12, and the two pusher rods 12 move together with the pusher plate 13. The pusher plate 13 pushes the transport cart 15 along the transport guide rail 16. After each transport cart 15 is pushed a distance, the pusher plate 13 retracts back to its initial position. Then, the lifting component moves down to lift the empty transport cart 15 on the circulating guide rail 17. At this time, the movable support bar 3 moves up, carrying the monocrystalline silicon and placing it on the transport cart 15. When the lifting rail 22 on the lifting component engages with the transport guide rail 16, the movable frame 7 moves again, pushing the transport cart 15 along the transport guide rail 16. On the transport guide rail 16, the subsequent transport cart 15 pushes the previous transport cart 15.

[0028] In some embodiments, the heating device includes a heating furnace 14, a conveying cart 15, a conveying guide rail 16, a circulating guide rail 17, a circulating drive component 18, a lifting component, and a lowering component. The input end of the heating furnace 14 cooperates with the feeding box 1, and the output end of the heating furnace 14 cooperates with the water cooling device. The conveying guide rail 16 is provided inside the heating furnace 14, and the conveying cart 15 is slidably disposed on the conveying guide rail 16. The bottom of the heating furnace 14 is fixedly provided with the circulating guide rail 17 cooperating with the conveying cart 15. The circulating drive component 18 is fixedly disposed on the heating furnace 14 and is used to drive the conveying cart 15 on the circulating guide rail 17 to move. The input end of the heating furnace 14 is fixedly provided with the lifting component cooperating with the conveying cart 15, and the output end of the heating furnace 14 is fixedly provided with the lowering component cooperating with the conveying cart 15. The top of the conveying cart 15 is provided with a groove cooperating with the movable support bar 3. The heating furnace 14 is a conventional heating furnace. A material conveying guide rail 16 is installed inside the heating furnace 14. A dividing strip 5 is fixedly installed on the material conveying cart 15 to prevent contact between the monocrystalline silicon and the material conveying cart 15. Under the action of the pusher plate 13, the material conveying cart 15 carries the monocrystalline silicon and moves within the heating furnace 14. The material conveying cart 15 at the output end of the heating furnace 14 enters the lifting track 22 on the lowering component from the material conveying guide rail 16. When the monocrystalline silicon on the material conveying cart 15 on the lowering component is removed by the unloading gripper 26, the lowering component is controlled to move downwards. The lowering component stops when the lifting track 22 on the lowering component engages with the circulating guide rail 17. Then, the existing circulating drive component 18 is controlled to work. The circulating drive component 18 drives the chain on the bottom of the heating furnace 14 to rotate. The hook on the chain drives the material transport vehicle 15 to move on the circulating guide rail 17 and then enters the lifting rail 22 on the lifting component. Then, the lifting component is controlled to drive the material transport vehicle 15 to move upward. When the lifting rail 22 on the lifting component is engaged with the material transport guide rail 16, the feeding device is controlled to put the monocrystalline silicon on the feeding device onto the material transport vehicle 15. Then, the material transport vehicle 15 continues to move and enter the material transport guide rail 16 through the pusher plate 13, so that the material transport vehicle 15 can achieve cyclic operation.

[0029] In some embodiments, both the lifting assembly and the lowering assembly include a lifting motor 19, a lifting rod 20, a lifting plate 21, and a lifting track 22.

A transmission shaft is fixedly mounted on the output shaft of the lifting motor 19, and a gear is mounted on the transmission shaft. Each lifting rod 20 is equipped with a rack that meshes with the gear. Thus, under the action of the lifting motor 19, the lifting rod 20 is driven to move up and down. The lifting plate 21 is fixedly mounted on the lower end of the lifting rod 20. The lifting plate 21 serves to mount the lifting track 22, which cooperates with the rollers on the lower side of the material transport vehicle 15.

[0030] In some embodiments, a closing door 23 is hinged to the output end of the heating furnace 14. The closing door 23 is hinged to the output end of the drive door cylinder 24, and the fixing part of the drive door cylinder 24 is hinged to the heating furnace 14. The drive door cylinder 24 is a cylinder in the prior art. Under the action of the drive door cylinder 24, the output end of the heating furnace 14 can be closed and opened through the closing door 23. After closing, the heat loss of the heating furnace 14 is reduced, so that the monocrystalline silicon can be heated better. After the closing door 23 is opened, it is convenient for the unloading gripper 26 to pick up the monocrystalline silicon on the material transport vehicle 15.

[0031] In some embodiments, the water cooling device includes a quench water tank 25, a discharge gripper 26, and a discharge drive 27.

The monocrystalline silicon is rapidly cooled after contacting the cooling water. A dividing strip 5 is fixedly installed on the unloading gripper 26 to prevent the monocrystalline silicon from contacting the unloading gripper 26 and being contaminated.

[0032] In some embodiments, the drying device includes a drying chamber 28, a feeding gripper 29, a feeding drive 30, and a drying conveying component 31.
