Description

Technical Field

[0001] This invention relates to the field of waste photovoltaic panel recycling technology, and more particularly to a hot knife separation and recycling device for waste photovoltaic panels. Background Technology

[0002] With the rapid development of the photovoltaic power generation industry, the number of waste photovoltaic panels is increasing daily. These panels contain valuable metals such as silver and aluminum; if not effectively recycled, they will not only waste resources but also pollute the environment. Currently, relatively efficient recycling technologies include physical and chemical methods. Physical methods include pyrolysis and hot-blade separation. Pyrolysis requires heating the waste photovoltaic panels to the point where the EVA film and plastic parts vaporize at high temperatures, allowing for the separation of glass, silicon wafers, and metals. However, this method requires a sealed environment, is time-consuming, and the pyrolysis gases need to be treated and discharged. Hot-blade separation technology offers advantages such as high separation efficiency and low energy consumption. However, existing hot-blade separation recycling equipment requires heating equipment to heat the blades to separate the glass and backsheet of the waste photovoltaic panels. Furthermore, if the temperature is not properly controlled, the EVA film softening time is prolonged, resulting in low separation efficiency. It may also cause residue at the interface between the waste photovoltaic panel and the hot blade, affecting the separation effect. Summary of the Invention

[0028] Furthermore, the technical fields and installation methods involved in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] For specific implementation examples, please refer to: Figures 1-8 A waste photovoltaic panel hot-knife separation and recycling device includes a support assembly 1, an adjustment assembly 4, a matching assembly 5, a separation blade 7, and a pushing assembly 8. The support assembly 1 includes a support frame 11, with an infeed assembly 2 and an outfeed assembly 9 installed in the middle of the support frame 11. Two sets of infeed assemblies 2 and 9 are provided, with the two sets of outfeed assemblies 9 located at both ends of the support frame 11. Two sets of infeed assemblies 2 are spaced apart on one side of the support frame 11, and the two sets of infeed assemblies 2 alternately transport waste photovoltaic panels 3. A mounting cavity is formed at the lower part of the support frame 11, and a fixing frame 16 is fixedly installed inside the mounting cavity. A set of fixed heating plates 6 is provided at both ends of the fixing frame 16, each set including multiple fixed heating plates 6 spaced apart. A matching assembly 5 is installed above each set of fixed heating plates 6, and the matching assembly 5 is slidably connected to the support assembly 1. The matching assembly 5 includes a parallel adsorption plate 56 and an auxiliary heating plate 57. The auxiliary heating plate 57 and the fixed heating plate 6 move up and down through the action of the screw and nut mechanism. The adsorption plate 56 and the auxiliary heating plate 57 can be flipped simultaneously through the worm gear mechanism. The adjustment component 4 is installed in the middle of the fixed frame 16. The side of the adjustment component 4 is equipped with a separation knife 7 that rotates in the horizontal direction. The auxiliary heating plate 57 and the fixed heating plate 6 contact the upper and lower surfaces of the waste photovoltaic panel 3 respectively and heat the waste photovoltaic panel 3. The pushing component 8 is installed below the adjustment component 4. The pushing component 8 includes four sets of pushing units. The four sets of pushing units are arranged symmetrically in pairs. The two sets of pushing units on the same side are fixedly connected by a crossbar 84. Each set of pushing units includes a threaded rod 83 that is raised and lowered. A push block 831 is set above the threaded rod 83. The push block 831 can pass through the gap between two adjacent fixed heating plates 6. The threaded rod 83 pushes the waste photovoltaic panel 3 to the delivery component 9 through the action of the moving cylinder 81.

[0030] The support frame 11 has fixed rods 12 fixed around its center. The bottom ends of the feeding component 2 and the feeding component 9 are fixed on the fixed rods 12. The fixed frame 16 includes a vertical rod 161 fixedly fixed in the center, and mounting plates 162 fixedly fixed on both sides of the vertical rod 161. Pushing units are installed on the mounting plates 162. Fixed plates 17 are fixedly fixed at both ends of the upper surface of the fixed frame 16. Two moving slots 171 are spaced apart on the fixed plates 17. The push block 831 can be raised and lowered through the moving slots 171. Guide rails 14 are horizontally fixed on both sides of the top of the support frame 11. A moving rack 15 is horizontally fixed in the middle of the top of the support frame 11. The guide rails 14 and the moving rack 15 are both located inside the support frame 11. The support component 1 is slidably connected to the cooperating component 5 through the guide rails 14. The guide rails 14 and the moving rack 15 are parallel to the moving direction of the feeding component 9.

[0031] A protective frame 13 is fixedly installed in the middle of the side of the support frame 11 away from the feeding component 2. A rotating cavity is formed between the protective frame 13 and the support frame 11. The rotating cavity is used for the rotation of the separating blade 7 to avoid affecting the external environment and causing safety accidents. The separating blade 7 is a blade with two sharp edges, which facilitates the alternating separation of the waste photovoltaic panels 3 located at both ends inside the support frame 11.

[0032] The adjustment assembly 4 further includes an adjustment box 41, a nut block 42, an adjustment component 43, a driving rotating gear 44, and a driven rotating gear 45; a connecting rod 411 is fixedly installed at the lower middle part of the adjustment box 41, and connectors 412 are fixedly installed at both ends of the connecting rod 411. The connectors 412 are fixedly installed on the fixing frame 16. A movable lead screw is rotatably installed inside the adjustment box 41, and a nut block 42 is threadedly connected to the movable lead screw. An adjustment component 43 is fixedly installed on the upper surface of the nut block 42. The adjustment component 43 is slidably connected to the adjustment box 41. The movable lead screw is driven to rotate by an adjustment motor (not shown in the figure), which drives the adjustment component 43 to move along the axial direction of the movable lead screw. The adjusting component 43 is a U-shaped component with its opening facing the protective frame 13. The adjusting component 43 is rotatably connected to the separating blade 7. The driven rotating gear 45 is coaxially fixedly connected to the rotating shaft of the separating blade 7, and the driven rotating gear 45 is located above the nut block 42. The driven rotating gear 45 is meshed with the driving rotating gear 44 on its side. The driving rotating gear 44 is driven to rotate by a flip motor (not shown in the figure), which drives the driven rotating gear 45 and the separating blade 7 to rotate 180°, so that the separating blade 7 rotates from the fixed heating plate 6 at one end of the support frame 11 to the fixed heating plate 6 at the other end of the support frame 11, thus separating the heated waste photovoltaic panel 3.

[0033] The separating blade 7 is heated to act as a hot blade for separating waste photovoltaic panels 3. The preheated waste photovoltaic panels 3 are easier to separate. Furthermore, the waste photovoltaic panels are preheated by the fixed heating plate 6 and the auxiliary heating plate 57, which shortens the separation process. The technology of heating the separating blade is existing technology.

[0034] The mating assembly 5 further includes a movable component 51, a fixed component 52, a lifting screw 53, a slide rod 54, a movable gear 55, a connecting shaft 58, and an extension plate 59. Two movable components 51 are provided, and the two movable components 51 are fixedly connected by spaced fixed components 52. One movable component 51 has a rotatable lifting screw 53 in its center, and the other movable component 51 has a fixed slide rod 54 in its center. A guide groove 511 is fixedly provided at the upper end of the movable component 51, and the movable component 51 slides into the guide rail 14 through the guide groove 511. A movable gear 55 is rotatably provided on one of the fixed components 52 near the adjusting assembly 4. The movable gear 55 meshes with a movable rack 15 and is driven to rotate by a movable motor (not shown in the figure), causing the mating assembly 5 to move along the guide rail 14. Two extension plates 59 are provided. One extension plate 59 has a connecting block 591 threadedly connected to the lifting screw 53, and the other extension plate 59 is slidably connected to the slide rod 54 via a fixed slider.

[0035] The adsorption plate 56 and the auxiliary heating plate 57 are connected by a connecting ear. The connecting shaft 58 passes through the connecting ear and is fixed. Multiple suction cups 561 are arranged circumferentially on the side of the adsorption plate 56 away from the auxiliary heating plate 57. The suction cups 561 are connected to a vacuum pump (not shown in the figure). The multiple suction cups 561 work together to adsorb photovoltaic glass. A pad 571 is arranged on the side of the auxiliary heating plate 57 away from the adsorption plate 56. The pad 571 works with the fixed heating plate 6 to adhere to the upper and lower sides of the waste photovoltaic panel 3, heating the waste photovoltaic panel 3 to soften the EVA film between the photovoltaic glass and the back sheet, making it easier for the separation knife 7 to perform the separation action.

[0036] The end of the connecting shaft 58 passes through the lower part of the extension plate 59 and is provided with a connector 581. The middle part of the connector 581 is fixedly connected to the connecting shaft 58 through a rotating sleeve. A worm gear 510 is fixedly sleeved on the outside of the rotating sleeve. A fixing block 592 is also fixedly provided on the extension plate 59. A worm 593 is rotatably provided on the fixing block 592. The worm 593 is connected to the worm gear 510. The worm 593 is driven to rotate by a rotary motor (not shown in the figure), which drives the connecting shaft 58 to rotate, thereby causing the adsorption plate 56 and the auxiliary heating plate 57 to rotate 180°.

[0037] The pushing unit also includes a threaded sleeve 82, a lifting driven gear 85, and a lifting driving gear 86. The moving cylinder 81 is horizontally mounted on the mounting plate 162. A mating block 811 is fixedly provided at the telescopic end of the moving cylinder 81. A threaded sleeve 82 is vertically rotatably provided at the end of the mating block 811. A threaded rod 83 is internally threaded to the threaded sleeve 82. A push block 831 is fixedly provided on the threaded rod 83. A lifting driven gear 85 is fixedly provided at the lower part of the threaded sleeve 82. A lifting driving gear 86 is rotatably provided on the side of the lifting driven gear 85. The lifting driving gear 86 is driven to rotate by a lifting motor (not shown in the figure), which drives the lifting driven gear 85 and the threaded sleeve 82 to rotate, thereby driving the threaded rod 83 to rise. This causes the push block 831 to pass through the corresponding moving groove 171 on the fixed plate 17 and the gap between two adjacent fixed heating plates 6 in sequence, and move to the top of the fixed heating plate 6. The telescopic end of the moving cylinder 81 is extended, driving the push block 831 to move closer to the waste photovoltaic panel 3 after the photovoltaic glass is separated, and pushing it onto the delivery component 9.

[0038] The feeding component 2 includes a conveyor frame 21, conveyor rollers 22, and diagonal braces 23. The diagonal braces 23 are fixedly mounted on the support frame 11, and the conveyor frame 21 is fixedly mounted above the diagonal braces 23. Multiple conveyor rollers 22 are rotatably arranged at intervals inside the conveyor frame 21. The multiple conveyor rollers 22 rotate synchronously through a sprocket and chain mechanism. The multiple conveyor rollers 22 cooperate to convey the waste photovoltaic panels 3. The waste photovoltaic panels 3 are waste photovoltaic panels with the frame and junction box removed. The waste photovoltaic panels 3 include a back sheet, a cell layer, and photovoltaic glass. The back sheet, cell layer, and photovoltaic glass are connected by EVA film. The structure and connection method of the feeding component 9 are the same as those of the feeding component 2. The feeding component 9 is used to convey the separated back sheet and cell layer, as well as the separated photovoltaic glass layer. Both the feeding component 2 and the feeding component 9 are existing technologies and will not be described in detail.

[0039] The operating procedure and working principle of this device are as follows:

[0040] S1: Multiple waste photovoltaic panels 3 are alternately transported to the corresponding fixed heating plate 6 through two feeding components 2. Adjust the moving gear 55 to rotate, driving the cooperating component 5 to move to the appropriate position above the corresponding waste photovoltaic panel 3. Adjust the auxiliary heating plate 57 to rotate so that the auxiliary heating plate 57 faces the waste photovoltaic panel 3. Adjust the lifting screw 53 to rotate so that the auxiliary heating plate 57 moves downward until the pad 571 is in contact with the upper surface of the waste photovoltaic panel 3. Adjust the movement of the auxiliary heating plate 57 and the fixed heating plate 6 to heat the waste photovoltaic panel 3 for a set time.

[0041] S2: Adjust one of the heating set times and move the auxiliary heating plate 57 upward to a suitable position; adjust the adsorption plate 56 to flip so that it faces the waste photovoltaic panel 3; adjust the adsorption plate 56 to move downward until the suction cup 561 adsorbs the photovoltaic glass on the waste photovoltaic panel 3; at the same time, adjust the separating blade 7 to rotate to the side of the waste photovoltaic panel 3 to be separated; adjust the separating blade 7 to move along the adjustment box 41; the separating blade 7 separates the photovoltaic glass from the battery cell layer and the base plate.

[0042] S3: Adjust the adsorption plate 56 to raise the photovoltaic glass to a suitable height; adjust the corresponding pushing unit below the separated waste photovoltaic panel 3, and the lifting drive gear 86 rotates, so that the push block 831 passes through the corresponding moving groove 171 on the fixed plate 17 and the gap between two adjacent fixed heating plates 6 in sequence, and moves to the top of the fixed heating plate 6. Adjust the moving cylinder 81 to extend, and drive the push block 831 to move closer to the waste photovoltaic panel 3 after the photovoltaic glass is separated, and push it onto the delivery component 9. The delivery component 9 transports the waste photovoltaic panel 3 after the photovoltaic glass is separated to the external recycling equipment; adjust the cooperating component 5 to move closer to the corresponding delivery component 9 until the photovoltaic glass moves above the delivery component 9. Adjust the adsorption plate 56 to descend, place the photovoltaic glass on the delivery component 9, and transport it to the external recycling equipment through the delivery component 9.

[0043] S4: The separating blade 7 moves to reset and rotates 180°, while the feeding component 2 conveys the waste photovoltaic panel 3 to the empty fixed heating plate 6 and heats it; the separating blade 7 moves to separate another waste photovoltaic panel 3 after heating for a set time, and repeats the above S2-S3.

[0044] S5: Repeat step S4 above until all waste photovoltaic panels 3 are separated.

[0045] This invention can preheat the waste photovoltaic panel 3 before separation. While preheating one waste photovoltaic panel 3, another preheated waste photovoltaic panel 3 can be separated by a hot knife using a separating blade 7. The separating blade 7 rotates and alternates to perform the separation operation of the waste photovoltaic panel 3, which can greatly improve the separation efficiency of the waste photovoltaic panel 3.
