Description

Technical Field

[0001] This invention relates to the field of crystalline silicon recycling technology for waste photovoltaic panels, specifically to a crystalline silicon recycling device for waste photovoltaic panels. Background Technology

[0002] The recycling of crystalline silicon from waste photovoltaic panels involves the following steps: frame removal → glass removal → shredding → crushing → sorting. First, a frame removal machine is used to remove the four frames of the photovoltaic panel. Then, the waste photovoltaic panel after frame removal is put into a glass removal machine to remove the surface glass. Next, the waste photovoltaic panel is put into a shredder for shredding. The shredded fragments are then put into a crusher for further crushing. After crushing, they enter a sorting machine to obtain crystalline silicon powder.

[0003] Currently, after the surface glass of existing waste photovoltaic panels is removed on a glass removal machine, a large number of fine glass fragments remain on the waste photovoltaic panels. Furthermore, due to the limitations in length and width of the waste photovoltaic panels, they need to be manually folded before being put into a shredder for shredding. During this process, the remaining fine glass fragments not only affect subsequent sorting but also pose certain safety hazards during manual folding. Therefore, we propose a crystalline silicon recycling device for waste photovoltaic panels. Summary of the Invention

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0049] Please see Figures 1 to 2 A crystalline silicon recycling device for waste photovoltaic panels includes a glass removal machine body 1 and a conveyor belt 2 set at the inlet and outlet of the glass removal machine body 1. The conveyor belt 2 at the outlet of the glass removal machine body 1 is provided with a support platform 3, and the support platform 3 is provided with a conveyor belt 31. That is, when the waste photovoltaic panels are glass removed, the waste photovoltaic panels are guided through the conveyor belt 2 to the conveyor belt 31 on the support platform 3, and the conveyor belt 31 realizes the conveying of the waste photovoltaic panels.

[0050] Please see Figures 3 to 10The support platform 3 is provided with a guide suction mechanism 4 on both sides. The guide suction mechanism 4 guides the photovoltaic panel after glass removal. The guide suction mechanism 4 includes a suction shell 41, a guide 42, a suction component 43 and a support rod 44. There are two suction shells 41. The two suction shells 41 are slidably arranged on both sides of the support platform 3. The suction shell 41 is provided with a suction port 411 on the side of the suction shell 41 closest to the support platform 3, and the guide 42 is located at the suction port 411.

[0051] The suction component 43 is located on the other side of the suction shell 41, and the support rod 44 is fixedly installed at the bottom of the support platform 3, with the two suction components 43 respectively located at both ends of the support rod 44.

[0052] The guide component 42 includes a guide shaft 421, a guide plate 422, a torsion spring 423, and a fixed side plate 424. The guide shaft 421 passes through the suction port 411 and is rotatably connected to the suction shell 41. The guide plate 422 is fixedly sleeved on the outside of the guide shaft 421. There are two guide plates 422, which are respectively fixedly installed at both ends of the guide shaft 421 and are fixedly installed on the outside of the suction shell 41.

[0053] A torsion spring 423 is sleeved on the outside of the guide shaft 421. One end of the torsion spring 423 is fixedly connected to the guide shaft 421, and the other end of the torsion spring 423 is fixedly connected to the fixed side plate 424.

[0054] A pusher plate 425 is also provided on the guide plate 422, and the fine glass removal mechanism 6 is connected to the pusher plate 425;

[0055] The suction component 43 includes a suction hood 431, a suction pipe 432, a blower 433, a support frame 434, a support sleeve 435, and a locking bolt 436. The suction hood 431 is fixedly installed on the outside of the suction shell 41, and the suction shell 41 has multiple suction holes corresponding to the position of the suction hood 431. One end of the suction pipe 432 is connected to the suction hood 431, and the other end of the suction pipe 432 is connected to the blower 433. The blower 433 is installed on the support frame 434, and the support frame 434 is fixedly installed on the bottom of the suction shell 41. The support frame 434 is slidably sleeved on the outside of the support rod 44. One end of the support sleeve 435 is fixedly connected to the support frame 434, and the support sleeve 435 is slidably sleeved on the outside of the support rod 44. The locking bolt 436 is threadedly connected to the support sleeve 435, and one end of the locking bolt 436 abuts against the support rod 44.

[0056] That is, the support frame 434 is fixed relative to the sliding rod at the bottom of the support platform 3 by the locking bolt 436 on the support sleeve 435. At the same time, the bottom of the support frame 434 is slidably connected to the bottom of the support platform 3. In this invention, the position of the support frame 434 relative to the support rod 44 can be adjusted by adjusting the locking bolt 436.

[0057] Specific implementation process: After the waste photovoltaic panels are removed from the glass removal machine body 1, they are conveyed along the winding mechanism 5 by the conveyor belt 31. At the same time, the guide plates 422 at the two suction shells 41 are distributed at a vertical angle with the support platform 3. The guide plates 422 are located at the suction port 411, which realizes the function of guiding the waste photovoltaic panels during the conveying process.

[0058] Please see Figures 4 to 10 The support platform 3 is also equipped with a fine glass removal mechanism 6, which works in conjunction with the guide suction mechanism 4 to remove fine glass from the surface of the photovoltaic panel after glass removal.

[0059] The small glass removal mechanism 6 includes a limiting plate 61, a walking frame 62, a first electric push rod 63, a support shell 64, a blower 65, an air blowing pipe 66, and an air blowing cover 67. There are two limiting plates 61, both of which are U-shaped, and both ends of the limiting plates 61 are fixedly installed on the support platform 3. The top of the limiting plate 61 is provided with a sliding groove 611, and both ends of the walking frame 62 are slidably connected to the sliding groove 611. One of the sliding grooves 611 is provided with a driving component 68, which is used to drive the walking frame 62.

[0060] The first electric push rod 63 is fixedly installed on the walking frame 62, and the output end of the first electric push rod 63 is fixedly connected to the support shell 64. The blower 65 is fixedly installed inside the support shell 64, and the output end of the blower 65 is connected to the air blowing pipe 66. The air blowing pipe 66 is connected to the air blowing cover 67. The air blowing cover 67 has multiple air blowing holes 671 on one side. In this application, the two ends of the air blowing cover 67 are inclined, so that the fine glass fragments can be guided by their inclined direction and guided to the two ends of the support platform 3. At the same time, the air blowing cover 67 has a pushing surface on one side, as shown in the attached specification. Figures 4 to 5 and instruction manual Figure 9 The pushing surface is set at an angle to push small pieces of glass.

[0061] The top of the air blowing hood 67 is provided with push blocks 672 at both ends, and the two push blocks 672 are slidably connected to the two push plates 425 respectively;

[0062] As a further explanation, the drive component 68 includes a drive screw and a drive motor. The drive screw is rotatably connected in one of the slide grooves 611, and the drive motor is installed on the outside of the limiting plate 61. The output end of the drive motor is fixedly connected to the drive screw. Thus, by running the drive motor, the drive screw is further rotated in the slide groove 611. When the drive screw rotates, it provides driving force to the walking frame 62. At the same time, under the limiting action of the slide groove 611 at the other end, the walking frame 62 moves along the top of the support platform 3.

[0063] Specific implementation process: When the waste photovoltaic panel after glass removal is moved to the winding mechanism 5 by the conveyor belt 31, the winding mechanism 5 fixes one end of the waste photovoltaic panel. Then, the first electric push rod 63 at the walking frame 62 runs, so that the bottom of the blowing hood 67 is in close contact with the surface of the waste photovoltaic panel. At this time, the conveyor belt 31 stops running. On the one hand, as the blowing hood 67 moves down, the two push blocks 672 push the push plate 425 respectively. Since one end of the push plate 425 is fixedly connected to the guide plate 422, the push plate 425 drives the guide plate 422 to rotate around the axis of the guide shaft 421. When the guide plate 422 rotates, the suction port 411 opens. The suction port 411 is fully opened after the bottom of the blowing hood 67 is in contact with the surface of the waste photovoltaic panel.

[0064] At this time, the walking frame 62 moves along the direction of the glass removal machine body 1 from the winding mechanism 5. While the walking frame 62 moves, the blower 65 runs, and the directional accelerated impact airflow is blown out through multiple air holes 671 at the blowing hood 67 to remove the fine glass fragments remaining on the surface of the waste photovoltaic panel. At the same time, as the blowing hood 67 moves, the blowing hood 67 pushes the fine glass fragments remaining on the surface of the waste photovoltaic panel.

[0065] At this time, the exhaust fans 433 at the two support frames 434 operate respectively, thereby generating negative pressure airflow at the suction shell 41 through the suction pipe 432 and the suction hood 431. At this time, in conjunction with the movement of the blowing hood 67, further fine glass fragments are sucked into the suction hood 431, thereby achieving the function of collecting fine glass fragments.

[0066] Once the air blowing hood 67 moves along the surface of the waste photovoltaic panel to the other end and the fine glass fragments on the surface of the waste photovoltaic panel are fully removed, the exhaust fan 433 and the blower 65 stop operating. At this time, the air blowing hood 67 presses one end of the waste photovoltaic panel to cooperate with the winding mechanism 5.

[0067] Please see Figures 1 to 3 and Figures 11 to 21 The support platform 3 is equipped with a winding mechanism 5 at the end away from the conveyor belt 2. The winding mechanism 5 is used to wind up the photovoltaic panels after the glass has been removed.

[0068] The coiling mechanism 5 includes a second electric push rod 51, a coiling frame 52, a moving plate 53, a moving part 54, a rotating shaft 55, a rotating part 56, and a coiling positioning part 7. The second electric push rod 51 is fixedly installed at the bottom of the support platform 3, and the output end of the second electric push rod 51 is fixedly connected to the coiling frame 52. The coiling frame 52 is slidably connected to the bottom of the support platform 3. There are two moving plates 53, which are slidably connected to the two ends of the coiling frame 52 respectively. The moving part 54 is installed on the coiling frame 52 and is used to drive the moving plate 53.

[0069] The rotating shaft 55 passes through the movable plate 53 and is rotatably connected to the movable plate 53. The rotating component 56 is installed on the coil rack 52 and is used to synchronously drive the two rotating shafts 55. The end of the rotating shaft 55 near the support platform 3 is fixedly connected to the rotating plate 57, and the coil positioning component 7 is installed on the rotating plate 57.

[0070] The coil positioning component 7 includes a reinforcing rod 71, a synchronization shell 72, a synchronization element 73, a synchronization plate 74, a semi-circular plate 75, a spreading element 76, and a pushing element 77. One end of the reinforcing rod 71 is fixedly connected to the rotating plate 57, and the other end of the reinforcing rod 71 is fixedly connected to the synchronization shell 72. The synchronization element 73 is disposed on the synchronization shell 72. Two synchronization plates 74 are provided, and one end of the two synchronization plates 74 is slidably connected to the synchronization shell 72. The synchronization element 73 is used to synchronously drive the two synchronization plates 74. The synchronization element 73 includes a bidirectional threaded screw and a synchronization... The motor and the bidirectional threaded screw are rotatably connected inside the synchronous housing 72, and the synchronous motor is mounted on the synchronous housing 72. The synchronous motor is used to drive the bidirectional threaded screw, so that the bidirectional threaded screw rotates inside the synchronous housing 72 through the operation of the synchronous motor. When the bidirectional threaded screw rotates, it provides driving force in opposite directions to the two synchronous plates 74. At the same time, under the limiting action of the synchronous housing 72, the two synchronous plates 74 respectively drive the two semicircular plates 75 to move in opposite directions.

[0071] One end of the synchronization plate 74 is fixedly connected to the semi-circular plate 75. The supporting member 76 is set on the synchronization plate 74, and the pushing member 77 is set on the outside of the synchronization shell 72. The pushing member 77 is used to synchronously drive the two supporting members 76.

[0072] The spreading member 76 includes a spreading plate 761, an inner side plate 762, and a spreading shaft 763. Multiple spreading plates 761 are provided, and one end of each spreading plate 761 is slidably connected to a semi-circular plate 75. A support groove 751 is provided on the semi-circular plate 75 at a position corresponding to the multiple spreading shafts 763. The spreading shaft 763 slides through the support groove 751, and one end of the spreading shaft 763 is fixedly connected to the spreading plate 761. The inner side plate 762 is fixedly installed on the inner side of the spreading plate 761. The pushing member 77 is used to drive the multiple inner side plates 762.

[0073] The pusher 77 includes a third electric push rod 771, a push frame 772, a push rod 773, a support 774, and a connecting support rod 775. The third electric push rod 771 is fixedly installed on the outside of the synchronization housing 72, and the output end of the third electric push rod 771 is fixedly connected to the push frame 772. The push frame 772 is provided with a push port 7721. One end of the push rod 773 slides through the push port 7721. The push rod 773 is provided with a limiting member 776 to limit its position relative to the push port 7721. The limiting member 776 includes a limiting circular plate. There are two limiting circular plates. Both limiting circular plates are fixedly installed on the push rod 773, and the two limiting circular plates are slidably connected to both sides of the push port 7721.

[0074] A connector is provided between the push rod 773 and the synchronization plate 74. Multiple connecting rods 775 are provided, and the multiple connecting rods 775 are distributed in two groups on the outside of the connecting rods 775. One end of the connecting rod 775 is rotatably connected to the push rod 773 through a hinge support, and the other end of the connecting rod 775 is rotatably connected to the inner side plate 762 through a pin. The connector includes a convex rod. One end of the convex rod is fixedly connected to the synchronization plate 74. The push rod 773 is provided with a guide groove at the position corresponding to the convex rod. The other end of the convex rod is slidably connected to the guide groove.

[0075] Specific implementation process: When one end of the waste photovoltaic panel moves to the support plate 761 at the two semicircles near the support platform 3, the synchronous component 73 moves along with the waste photovoltaic panel, and the multiple support plates 761 at the two sets of semicircles 75 clamp and fix one end of the waste photovoltaic panel to each other.

[0076] After the fine glass fragments on the surface of the waste photovoltaic panel are removed, the rotating component 56 operates, causing the two rotating plates 57 at both ends of the waste photovoltaic panel to rotate synchronously. As the rotating plates 57 rotate, the multiple spreading plates 761 on the semi-circular plate 75 achieve the function of winding the waste photovoltaic panel. Simultaneously, the air blowing hood 67 drives the waste photovoltaic panel to move in the opposite direction of the rotating plates 57, thus ensuring a sufficiently stable winding of the waste photovoltaic panel. Once the waste photovoltaic panel is fully wound, the air blowing hood 67 presses down on the other end of the waste photovoltaic panel. Therefore, when it is necessary to wind the rolled waste photovoltaic panel... When the board is removed, the third electric push rod 771 is operated, which causes the push frame 772 to drive the two push rods 773 to move synchronously. When the two push rods 773 move, they drive multiple connecting support rods 775 to move synchronously. At this time, under the limiting action of the opening shaft 763, the multiple opening rods move towards each other, so that the multiple opening rods are relatively separated from the inner ring of the rolled waste photovoltaic panel. At this time, one of the moving parts 54 operates, causing a set of opening plates 761 to be separated from the rolled waste photovoltaic panel. Then, the workers can take out the rolled waste photovoltaic panel for the next processing step. Example 2

[0077] Please see Figure 14 Example 2 is a further supplementary description of the moving part 54 in Example 1. Specifically, the moving part 54 includes a moving screw 541 and a moving motor 542. The moving screw 541 is rotatably connected to one end of the coil frame 52, and the moving motor 542 is mounted on the coil frame 52. The moving motor 542 is used to drive the moving screw 541. The moving plate 53 is threaded onto the outside of the moving screw 541.

[0078] Specific implementation process: When the position of the moving plate 53 relative to the coil frame 52 is adjusted, the moving motor 542 runs, causing the moving screw 541 to rotate. When the moving screw 541 rotates, it provides driving force to the moving plate 53. At this time, under the limiting action of the coil frame 52, the moving plate 53 moves further along the coil frame 52, thereby realizing the function of adjusting the position of the moving plate 53 relative to the coil frame 52. Example 3

[0079] Please see Figures 11 to 14Example 3 further supplements the description of the rotating component 56 in Example 1. Specifically, the rotating component 56 includes a rotating motor 561, a rotating rod 562, a rotating sleeve 563, a first rotating wheel 564, a second rotating wheel 565, and a synchronous belt 566. The rotating motor 561 is mounted on the coil frame 52, and the output end of the rotating motor 561 is fixedly connected to the rotating rod 562. The rotating rod 562 is rotatably connected to the coil frame 52. Two protrusions 5621 are provided on the outer side of the rotating rod 562, and two movable plates 53 are respectively sleeved on the outer side of the rotating rod 562. On one side, one end of the rotating sleeve 563 is rotatably connected to the moving plate 53, and the rotating sleeve 563 is slidably sleeved on the outside of the rotating rod 562. The rotating sleeve 563 is provided with two grooves corresponding to the positions of the two protrusions 5621, and the rotating sleeve 563 is slidably sleeved on the outside of the two protrusions 5621 through the two grooves. The first rotating wheel 564 is fixedly sleeved on the outside of the rotating sleeve 563, and the second rotating wheel 565 is fixedly sleeved on the outside of the rotating shaft 55. The synchronous belt 566 is used to transmit power between the first rotating wheel 564 and the second rotating wheel 565.

[0080] The rotating motor 561 operates, which in turn causes the rotating rod 562 to rotate. As the rotating rod 562 rotates, the two protrusions 5621 drive the two rotating sleeves 563 to rotate synchronously. As the rotating sleeves 563 rotate, the first rotating wheel 564, the timing belt 566, and the second rotating wheel 565 further cause the rotating shaft 55 to rotate. As the rotating shaft 55 rotates, the rotating plate 57 rotates synchronously.
