Technical Field

[0001] The present invention relates to the technical field of photovoltaic component recycling, and in particular to a photovoltaic component recycling device and method. Background Art

[0002] EVA is a hot melt adhesive film, mainly used in the production of photovoltaic modules. Ordinary photovoltaic modules are placed from top to bottom with tempered glass, EVA, battery cells, EVA, and TPT. In the laminator, through vacuuming, heating, and pressurizing, the EVA melts and the layers are tightly bonded together to isolate the battery cells from the air.

[0003] In solar power generation technology, photovoltaic power generation has always occupied a dominant position in the industry. With the commissioning of large-scale centralized and distributed photovoltaic power generation projects, the problem of handling discarded photovoltaic modules will become increasingly prominent.

DETAILED DESCRIPTION

[0039] A photovoltaic module recycling device, such as Figure 1-13As shown, it includes a base plate 1, and a pair of first support plates 3 and second support plates 2 are respectively arranged on both sides of the base plate 1, and a differentiation structure for heating the upper end surface of the photovoltaic panel while controlling the up and down micro-folding of the photovoltaic panel is respectively arranged between the first support plates 3 and the second support plates 2, and a first slide plate 6 is respectively slidably connected between the first support plate 3 and the second support plate 2, and an adjustable belt structure matched with the differentiation structure is arranged between the first slide plates 6, and the adjustable belt structure respectively includes a lower fixed rotating wheel 10 and a belt rotating wheel 11 which rotate in the opposite direction and have adjustable spacing, and the differentiation structure is driven and connected with a splitting and recycling structure, and the splitting and recycling structure includes a cutting blade 31 with adjustable height, and an air blast cooling structure matched with the differentiation structure is also arranged between the first slide plates 6, and the air blast cooling structure includes an air outlet 52 with continuously changing blowing intensity.

[0040] When the present invention is in use, the photovoltaic panel to be disassembled is heated and slightly folded to form a differentiated structure, and then the glass plate and EVA are softened and dispersed. The photovoltaic panel is driven forward by the adjustable accompanying structure, and the driving spacing can be adjusted according to the thickness of the photovoltaic panel. After the photovoltaic panel is softened and dispersed, in order to avoid the glass plate and EVA from being re-adhered, the air blast cooling structure is operated, and air is blown by the air outlet pipe 52 to perform air blast cooling between the glass plate and the EVA. The height of the cutting blade 31 is adjusted, and the cutting blade 31 is aligned with the dividing part of the glass plate. As the photovoltaic panel continues to move, the glass plate is disassembled and separated as a whole by the cutting blade 31, thereby realizing the overall recycling of the glass plate.

[0041] like Figure 6 and 7 As shown in 10, the differentiation structure also includes a second motor 26 connected to the frame plate 57, the output ends of the second motor 26 are respectively fixedly connected to the driving sprocket 27 and the rotating rod 48, the driving sprocket 27 is respectively connected to the first driven sprocket 28 and the second driven sprocket 35 through a chain belt, the first driven sprocket 28 is coaxially fixedly connected to the first friction column 29, the upper end of the first friction column 29 is provided with a heating cylinder 9 connected to the first support plate 3, the upper end of the second friction column 30 is provided with a rotating cylinder 8 connected to the second support plate 2, the heating cylinder 9 and the rotating cylinder 8 are respectively fixedly connected to the sliding shaft block 34 at both ends, the upper end of the sliding shaft block 34 is provided with a fixed shaft block 33 fixedly connected to the first support plate 3, a spring 32 is provided between the fixed shaft block 33 and the sliding shaft block 34, one end of the rotating rod 48 is rotatably connected to the connecting rod 49, one end of the connecting rod 49 is rotatably connected to the first slide plate 6, and the two ends of the first slide plate 6 are respectively provided with first sliding pins 7 slidably connected to the inner walls of the first support plate 3 and the second support plate 2.

[0042] Furthermore, the second motor 26 works, and the output end of the second motor 26 drives the active sprocket 27 and the rotating rod 48 to rotate. During the rotation of the active sprocket 27, the first driven sprocket 28 and the second driven sprocket 35 are driven to rotate in the same direction through the chain belt. During the rotation of the first driven sprocket 28, the first friction column 29 is driven to rotate, and the second driven sprocket 35 drives the second friction column 30 to rotate, so that the photovoltaic panel is transported between the first friction column 29 and the heating cylinder 9, and the friction wheel between the first friction column 29 and the photovoltaic panel is used to drive the photovoltaic panel to move, and the heating cylinder 9 is used to heat and soften the glass plate and EVA on the upper end of the photovoltaic panel, and the spring set between the fixed shaft block 33 and the sliding shaft block 34 32, which plays the role of resetting and pressing down the heating cylinder 9 and the rotating cylinder 8, ensuring that the heating cylinder 9 and the photovoltaic panel are tightly connected in rotation, and the heating effect is better. The rotating rod 48 drives the connecting rod 49 to swing up and down during the circular rotation. Since one end of the connecting rod 49 is slidably connected to the first slide plate 6, the first slide plate 6 is driven by the connecting rod 49 to slide up and down on the inner walls of the first support plate 3 and the second support plate 2, thereby driving different parts of the photovoltaic panel to fold up and down. The glass plate on the photovoltaic panel is usually tempered glass. The tempered glass can be slightly folded without breaking when heated. During the micro-folding process, the glass plate and EVA will soften and disperse, which is convenient for separation after a gap is generated between the two.

[0043] like Fig.13 As shown, a heating tube 56 is arranged in the heating tube 9, and the heating tube 9 is made of a metal material with strong thermal conductivity.

[0044] Furthermore, the heating tube 56 transfers heat to the glass plate on the photovoltaic panel through the heating cylinder 9 .

[0045] like Figure 1 and 2 As shown, a first carrier plate 5 is fixedly connected between the first support plate 3 and the second support plate 2 at the rear end of the base plate 1, and a second carrier plate 4 is fixedly connected between the first support plate 3 and the second support plate 2 at the front end of the base plate 1, and the upper arc surface of the first carrier plate 5 and the first friction column 29 are flush with each other, and the upper arc surface of the second carrier plate 4 and the second friction column 30 are flush with each other.

[0046] Furthermore, the first carrier plate 5 and the second carrier plate 4 are used to carry the input and discharge of photovoltaic panels, and the upper arc surfaces of the first carrier plate 5 and the first friction column 29 are flush, and the upper arc surfaces of the second carrier plate 4 and the second friction column 30 are flush, which facilitates the use of the friction force of the first friction column 29 and the second friction column 30 to input and discharge the photovoltaic panels.

[0048] Furthermore, the second friction column 30 drives the groove wheel 36 to rotate during the rotation. During the rotation of the groove wheel 36, its inner groove cooperates with the latch 38, and then drives the slider 37 to move horizontally back and forth through the latch 38. The slider 37 drives the connecting column 39 to move, and a limiting column plate slidably connected to the connecting column 39 is provided on the second support plate 2. The limiting column plate plays a role of limiting support for the connecting column 39. The connecting column 39 drives the mounting block 42 to move, and the mounting block 42 indirectly drives the cutting blade 31 to move back and forth. The cutting blade 31 is used to cut and separate the dividing point of the glass plate and the EVA. Since the arc grooves at both ends of the groove wheel 36 are in a shaking arc shape, the cutting blade 31 shakes back and forth at the dividing point of the glass plate and the EVA, which is convenient for quickly separating the adhesion between the glass plate and the EVA, and can also avoid the glass plate from breaking, thereby ensuring the integrity of the glass plate.

[0049] like Figure 8 and 9 As shown, the inner wall of the mounting block 42 is rotatably connected to a worm 44, the worm 44 is meshed with a worm wheel 45, the worm wheel 45 is fixedly connected to a second screw 41, one end of the cutting blade 31 is fixedly connected to a mounting rod 46, the inner wall of the mounting rod 46 is fixedly connected to a second screw barrel 47 threadedly connected to the second screw 41, and one end of the mounting block 42 is also provided with a limiting rod 40 slidably connected to the inner wall of the mounting rod 46.

[0050] Furthermore, a turning handle 43 is provided at one end of the worm 44, and the turning handle 43 is used to control the rotation of the worm 44, which drives the worm wheel 45 to rotate, and the worm wheel 45 drives the second screw 41 to rotate. During the rotation of the second screw 41, the second screw 41 is threadedly engaged with the second screw barrel 47 on the inner wall of the mounting rod 46, thereby driving the mounting rod 46 to move up and down under the limit of the limit rod 40, thereby adjusting the height of the cutting blade 31, so as to facilitate the adjustment of the position of the cutting blade 31 at the adhesion point of the glass plate and EVA according to the thickness of the photovoltaic panel.

[0051] like Figure 3 and 4As shown, the adjustable belt-belt structure also includes a first motor 13 fixedly connected to the first slide plate 6, the output end of the first motor 13 is fixedly connected to the first transmission rod 18, the lower end of the first transmission rod 18 is fixedly connected to the first active bevel gear 14, the upper end of the first transmission rod 18 is provided with a second active bevel gear 16, the first active bevel gear 14 is meshed with a first driven bevel gear 15, the first driven bevel gear 15 is fixedly connected to the lower fixed rotating wheel 10, the second active bevel gear 16 is meshed with a second driven bevel gear 17, the second driven bevel gear 17 is fixedly connected to the belt-belt rotating wheel 11, a second slide plate 23 and a fixed plate 24 are respectively provided between the first slide plates 6, the two ends of the second slide plate 23 are respectively provided with second sliding pins 25 slidably connected to the inner wall of the first slide plate 6, the second slide plate 23 is provided with the said belt-belt rotating wheel 11, and a plurality of friction plates 12 are evenly arranged on the circumference of the belt-belt rotating wheel 11.

[0052] Furthermore, the first motor 13 works, and the output end of the first motor 13 drives the first transmission rod 18 to rotate, and the first transmission rod 18 drives the first active bevel gear 14 to rotate, and the first active bevel gear 14 drives the first driven bevel gear 15 to rotate, and the first driven bevel gear 15 drives the lower fixed rotating wheel 10 to rotate. Since the upper end of the first transmission rod 18 is provided with a spline, the first transmission rod 18 drives the second active bevel gear 16 to rotate during the rotation, and the second active bevel gear 16 drives the second driven bevel gear 17 to rotate, and the second driven bevel gear 17 drives the accompanying rotating wheel 11 to rotate, and the rotation directions of the accompanying rotating wheel 11 and the lower fixed rotating wheel 10 are opposite, so the accompanying rotating wheel 11 and the lower fixed rotating wheel 10 cooperate to drive the photovoltaic panel to move, and the friction plate 12 on the accompanying rotating wheel 11 can not only increase the friction with the photovoltaic panel but also effectively reduce the contact surface with the glass plate on the photovoltaic panel, which can effectively reduce the area of ​​re-adhesion between the heated glass plate and EVA, and play a convenient role in subsequent cutting and separation.

[0053] like Figure 3 and 5 As shown, a connecting plate 19 is further provided between the first slide plates 6, the inner wall of the connecting plate 19 is fixedly connected with a first screw barrel 22, the first screw barrel 22 is threadedly connected with a first screw rod 21, and the lower end of the first screw rod 21 is rotatably connected to the second slide plate 23.

[0054] Furthermore, a handle 20 is provided at one end of the first screw 21, and the rotation of the first screw 21 is controlled by the handle 20. The first screw 21 is threadedly engaged with the first screw barrel 22 on the inner wall of the connecting plate 19, and since the lower end of the first screw 21 is rotatably connected with the second slide plate 23, the second slide plate 23 can be controlled to slide along the inner wall of the first slide plate 6, and then the distance between the accompanying rotating wheel 11 on the second slide plate 23 and the lower fixed rotating wheel 10 on the fixed plate 24 can be adjusted to adapt to photovoltaic panels of different types and thicknesses.

[0055] like Figure 2 and 11 As shown in 12, the air blast cooling structure also includes a pair of blowers 53 respectively connected to the first slide plate 6, and the outlet end of the blower 53 is provided with an air outlet tube 52 connected to the first slide plate 6, the first driven bevel gear 15 is coaxially fixedly connected to a driving pulley 54, the driving pulley 54 is connected to a driven pulley 55, the driven pulley 55 is fixedly connected to a second transmission rod 50 rotatably connected to the first slide plate 6, and both ends of the second transmission rod 50 are respectively fixedly connected to arc-shaped baffles 51 corresponding to the air outlet tube 52.

[0056] Furthermore, the wind blown by the blower 53 is discharged through the air outlet tube 52. During the rotation of the first driven bevel gear 15, the driving pulley 54 is driven to rotate. The driving pulley 54 drives the driven pulley 55 to rotate. The driven pulley 55 drives the second transmission rod 50 to rotate. The second transmission rod 50 drives the arc baffle 51 to rotate in a circle. Since the arc baffle 51 blocks different areas of the air outlet on the air outlet tube 52 during the rotation, the air outlet intensity of the air outlet tube 52 is adjusted, which is convenient for rapid air blowing cooling between glass plates and EVA at different positions to avoid re-pasting of the glass plates and EVA.

[0057] The working process of the present invention is as follows: when the present invention is in use, the second motor 26 works, the output end of the second motor 26 drives the driving sprocket 27 and the rotating rod 48 to rotate, and during the rotation of the driving sprocket 27, the first driven sprocket 28 and the second driven sprocket 35 are driven to rotate in the same direction through the chain belt, and during the rotation of the first driven sprocket 28, the first friction column 29 is driven to rotate, and the second driven sprocket 35 drives the second friction column 30 to rotate, so that the photovoltaic panel is transported between the first friction column 29 and the heating cylinder 9, and the friction wheel between the first friction column 29 and the photovoltaic panel is used to drive the photovoltaic panel to move, and the heating cylinder 9 is used to The glass plate and EVA on the upper end of the photovoltaic panel are heated and softened, and the rotating rod 48 drives the connecting rod 49 to swing up and down during the circular rotation. Since one end of the connecting rod 49 is slidably connected to the first slide plate 6, the first slide plate 6 is driven by the connecting rod 49 to slide up and down on the inner walls of the first support plate 3 and the second support plate 2, thereby driving different parts of the photovoltaic panel to fold slightly up and down. The glass plate on the photovoltaic panel is usually made of tempered glass, which can be slightly folded without breaking when heated. During the micro-folding process, the glass plate and EVA will soften and disperse, which is convenient for separation after a gap is created between the two.

[0058] The first motor 13 is working, and the output end of the first motor 13 drives the first transmission rod 18 to rotate, the first transmission rod 18 drives the first active bevel gear 14 to rotate, the first active bevel gear 14 drives the first driven bevel gear 15 to rotate, and the first driven bevel gear 15 drives the lower fixed rotating wheel 10 to rotate. Since the upper end of the first transmission rod 18 is provided with a spline, the first transmission rod 18 drives the second active bevel gear 16 to rotate during the rotation, the second active bevel gear 16 drives the second driven bevel gear 17 to rotate, and the second driven bevel gear 17 drives the accompanying rotating wheel 11 to rotate, and the rotation directions of the accompanying rotating wheel 11 and the lower fixed rotating wheel 10 are opposite, so the accompanying rotating wheel 11 and the lower fixed rotating wheel 10 cooperate to drive the photovoltaic panel to move. The friction plate 12 on the belt wheel 11 can not only increase the friction with the photovoltaic panel but also effectively reduce the contact area with the glass plate on the photovoltaic panel, which can effectively reduce the area of ​​re-adhesion between the heated glass plate and EVA, and facilitate the subsequent cutting and separation. The rotation of the first screw 21 is controlled by the handle 20. The first screw 21 is threadedly engaged with the first screw barrel 22 on the inner wall of the connecting plate 19. Since the lower end of the first screw 21 is rotatably connected with the second slide plate 23, the second slide plate 23 can be controlled to slide along the inner wall of the first slide plate 6, and then the distance between the belt wheel 11 on the second slide plate 23 and the lower fixed wheel 10 on the fixed plate 24 can be adjusted to adapt to photovoltaic panels of different types and thicknesses.

[0059] The wind blown by the blower 53 is discharged through the air outlet tube 52. The first driven bevel gear 15 drives the driving pulley 54 to rotate during its rotation. The driving pulley 54 drives the driven pulley 55 to rotate. The driven pulley 55 drives the second transmission rod 50 to rotate. The second transmission rod 50 drives the arc baffle 51 to rotate in a circle. Since the arc baffle 51 blocks different areas of the air outlet holes on the air outlet tube 52 during its rotation, the air outlet intensity of the air outlet tube 52 is adjusted, so as to quickly cool the glass plate and EVA at different positions during the movement and avoid re-pasting the glass plate and EVA.

[0060] The worm 44 is controlled to rotate by the turning handle 43, the worm 44 drives the worm wheel 45 to rotate, and the worm wheel 45 drives the second screw 41 to rotate. During the rotation of the second screw 41, the second screw 41 cooperates with the second screw barrel 47 on the inner wall of the mounting rod 46 through the thread, thereby driving the mounting rod 46 to move up and down under the limit of the limit rod 40, thereby adjusting the height of the cutting blade 31, so as to facilitate the adjustment of the position of the cutting blade 31 at the adhesion point of the glass plate and EVA according to the thickness of the photovoltaic panel.

[0061] At the same time, the second friction column 30 drives the groove wheel 36 to rotate during its rotation. During the rotation of the groove wheel 36, its inner groove cooperates with the latch 38, and then drives the slider 37 to move horizontally back and forth through the latch 38. The slider 37 drives the connecting column 39 to move, and a limiting column plate slidably connected to the connecting column 39 is provided on the second support plate 2. The limiting column plate plays a role of limiting support for the connecting column 39. The connecting column 39 drives the mounting block 42 to move, and the mounting block 42 indirectly drives the cutting blade 31 to move back and forth. The cutting blade 31 is used to cut and separate the dividing point of the glass plate and the EVA. Because the arc grooves at both ends of the groove wheel 36 are in a shaking arc shape, the cutting blade 31 shakes back and forth at the dividing point of the glass plate and the EVA, which is convenient for quickly separating the adhesion between the glass plate and the EVA, and can also avoid the glass plate from breaking, thereby ensuring the integrity of the glass plate.

[0062] A recycling method of a photovoltaic module recycling device specifically comprises the following steps:

[0063] S1. After the photovoltaic panel to be disassembled is heated by the heating cylinder 9, it is moved between the belt rotating wheel 11 and the lower fixed rotating wheel 10 under the cooperation of the first friction wheel. Under the limit of the heating cylinder 9 and the rotating cylinder 8, the photovoltaic panel is slightly folded with the ups and downs of the first slide plate 6, and the glass plate and EVA are softened and dispersed;

[0064] S2. After the photovoltaic panel passes through the heating cylinder 9, it is driven forward by the accompanying rotating wheel 11 and the lower fixed rotating wheel 10. Under the limit of the heating cylinder 9 and the rotating cylinder 8, the photovoltaic panel is slightly folded with the ups and downs of the first slide plate 6, and the glass plate and EVA are softened and dispersed. The distance between the accompanying rotating wheel 11 and the lower fixed rotating wheel 10 can be adjusted according to the thickness of the photovoltaic panel, so that the photovoltaic panel can be driven forward;

[0065] S3. After the photovoltaic panel softens and disperses, in order to avoid the glass plate and EVA from being re-pasted, the air outlet 52 is used to blow air to cool the glass plate and EVA. Since the arc-shaped baffle 51 blocks the shielding area of ​​the air outlet hole on the air outlet 52 during the rotation process, the air outlet intensity of the air outlet 52 is adjusted, so that the air is quickly blown to cool the glass plate and EVA at different positions to avoid the glass plate and EVA from being re-pasted;

[0066] S4. Adjust the height of the cutting blade 31 and align the cutting blade 31 with the dividing portion of the glass plate. As the glass plate continues to move with the photovoltaic panel, the cutting blade 31 is used to disassemble and separate the glass plate as a whole, thereby realizing the overall recycling of the glass plate.

[0067] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
