Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste photovoltaic panel recycling technology, and in particular to a waste photovoltaic panel dismantling and separation device. Background Technology
[0002] With the increasing global demand for clean energy, photovoltaic (PV) power generation, as an important renewable energy source, has been widely applied and developed rapidly. However, PV panels have a limited lifespan, and the large number of old PV panels generated has brought serious environmental and resource problems. On the one hand, if discarded PV panels are not properly disposed of, the heavy metals and harmful substances they contain can cause serious pollution to the soil, water sources, and other ecological environments, affecting ecological balance and human health. On the other hand, the silicon, silver, aluminum, and other metals, as well as glass and other materials in PV panels, have high recycling value. Recycling and reusing them can reduce resource waste, lower the demand for primary mineral mining, and align with the concept of sustainable development. Therefore, recycling old PV panels has extremely important practical significance and urgency.
[0003] However, silicon wafers and glass plates are usually connected by adhesives. This connection method makes them tightly bonded, making it difficult to disassemble them without damage. When attempting to separate the silicon wafer and glass plate, the adhesive properties often require a large amount of external force, which can easily damage both the glass and the silicon wafer. Once the silicon wafer cracks, breaks, or has surface damage, its internal crystal structure is destroyed, which seriously affects the reuse value of the silicon material and makes it unable to meet the requirements for remanufacturing high-quality photovoltaic cells. Similarly, damage to the glass not only reduces its integrity and usability after recycling, but also increases the difficulty and cost of subsequent sorting and processing, greatly hindering the efficient development of the photovoltaic panel recycling industry.
[0004] Therefore, those skilled in the art have proposed a device for dismantling and separating waste photovoltaic panels. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste photovoltaic panel dismantling and separation device. This device uses organic solvents and pressure additives to thermally decompose old photovoltaic panels. Simultaneously, by utilizing the rotation of pressure fan blades, the solvent and pressure additives are propelled by the pressure fan blades during the solvent input process, thereby improving the contact efficiency between the solvent, pressure additives, and photovoltaic panels, which is beneficial for the separation of silicon wafers and glass.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A waste photovoltaic panel dismantling and separation device includes a dismantling machine, a heating platform installed on the dismantling machine, and a mechanical splitting platform located behind the heating platform. A dismantling mechanism is placed above the heating platform. The dismantling mechanism includes a dismantling box. A locking door is hinged to the rear side wall of the dismantling box. The rear side wall of the dismantling box and the front side wall of the locking door are respectively provided with mutually cooperating locking grooves and locking latches. Side mounting brackets are fixedly connected to the bottom of both side walls of the dismantling box. A centering adjustment mechanism is installed in the middle of the front side wall of the dismantling box. The centering adjustment mechanism includes a centering cylinder. A connecting rod is fixedly connected to the movable end of the centering cylinder. Drive wedge plates are fixedly connected to both ends of the bottom of the connecting rod. Centering plates are connected to the two side mounting brackets by springs. The drive wedge plates cooperate with the wedge grooves on the front side of the centering plates. A shovel plate is fixedly connected to the middle of the front side wall of the connecting rod.
[0008] The above technical solution involves placing the old photovoltaic panels to be dismantled into the decomposition mechanism for thermal decomposition. Before thermal decomposition, the locking door is opened, and the photovoltaic panels are placed into the decomposition box from the rear. The locking door is then locked back into the rear of the decomposition box using a locking mechanism. The centering cylinder is then activated. When the centering cylinder is activated, it drives the connecting rods on both sides to move the drive wedge plate forward, thereby moving the two centering plates towards the center, thus centering the photovoltaic panels. Subsequently, the shovel plate on the front side of the connecting rod pushes the photovoltaic panels to the rear, allowing the photovoltaic panels to accurately reach the target position in the decomposition box.
[0009] Furthermore, a feed pipe is fixedly connected to the middle position of the right side wall of the decomposition box;
[0010] Through the above technical solution, the feed pipe is used to inject organic solvent and pressure additive into the decomposition box, thereby simultaneously heating the photovoltaic panel to form thermal decomposition, which is beneficial to the separation of silicon wafer and glass.
[0011] Furthermore, a solvent pressurizing mechanism is installed on the outer wall of the feed pipe. The solvent pressurizing mechanism includes a drive motor. A front baffle is fixedly connected to the left end of the inner wall of the feed pipe. A drive shaft is fixedly connected to the middle of the front baffle. A cleaning end toothed cone and a pressurizing end toothed cone are rotatably connected to the left and right ends of the outer wall of the drive shaft, respectively. A drive toothed cone is fixedly connected to the movable end of the drive motor. The drive toothed cone meshes with the cleaning end toothed cone and the pressurizing end toothed cone, respectively. A pressurizing end helical toothed cylinder is fixedly connected to the right side wall of the pressurizing end toothed cone. A pressurizing fan blade is slidably connected to the right end of the drive shaft. A pressurizing end sliding helical toothed cylinder is fixedly connected to the left side wall of the pressurizing fan blade. The pressurizing end sliding helical toothed cylinder and the pressurizing end helical toothed cylinder cooperate with each other. A return spring is sleeved between the pressurizing fan blade and the front baffle.
[0012] Through the above technical solution, during the solvent injection stage, when the motor rotates in the forward direction, the pressure end tooth cone rotates counterclockwise while the cleaning end tooth cone rotates clockwise. At this time, the pressure end helical tooth cylinder drives the pressure end sliding helical tooth cylinder to rotate, which in turn drives the pressure fan blade to rotate. This allows the solvent and pressure additive to be pushed by the pressure fan blade during the solvent injection process, thereby improving the contact efficiency between the solvent, pressure additive and photovoltaic panel.
[0013] Furthermore, a cleaning end inclined toothed cylinder is fixedly connected to the left end of the cleaning end toothed cone, a cleaning end sliding inclined toothed cylinder is slidably connected to the left end of the drive shaft, a filter plate is fixedly connected to the left end of the drive shaft, a cleaning brush is fixedly connected to the cleaning end sliding inclined toothed cylinder, and a spring is sleeved between the cleaning end sliding inclined toothed cylinder and the filter plate.
[0014] With the above technical solution, when the motor rotates in the forward direction, the pressure end tooth cone rotates counterclockwise while the cleaning end tooth cone rotates clockwise. At this time, the cleaning end inclined tooth cylinder pushes the cleaning end sliding inclined tooth cylinder forward through the inclined tooth structure, without causing the cleaning end sliding inclined tooth cylinder to rotate, thereby reducing the contact time between the cleaning brush and the filter plate and avoiding unnecessary wear on the cleaning end sliding inclined tooth cylinder. When solvent needs to be discharged, the motor rotates in the reverse direction. At this time, the pressure end tooth cone rotates clockwise while the cleaning end tooth cone rotates counterclockwise. At this time, the cleaning end inclined tooth cylinder drives the cleaning end sliding inclined tooth cylinder to rotate, thereby using the cleaning brush to continuously brush off the waste residue blocking the filter plate, preventing the waste residue from clogging the filter plate mesh. At this time, the pressure end inclined tooth cylinder drives the pressure fan blade to move back and forth through the inclined tooth structure, avoiding the rotation of the pressure fan blade during the discharge process, which would cause adverse interference to the discharge.
[0015] Furthermore, a recycling mechanism is detachably connected to the middle position of the lower side wall of the feed pipe. The recycling mechanism includes a recycling box, and a spring rod is installed on the lower inner wall of the recycling box through spring rubber material. The spring rod is used in conjunction with the cleaning brush.
[0016] With the above technical solution, when the cleaning brush rotates to the position of the spring rod, it will collide with the spring rod, thereby shaking the waste debris adhering to the brush head into the recycling box for recycling.
[0017] This utility model has the following beneficial effects:
[0018] In this invention, an organic solvent and a pressure additive are injected, and a heating platform is used to heat the photovoltaic panel, resulting in thermal decomposition, which facilitates the separation of the silicon wafer and the glass.
[0019] In this invention, during the solvent injection stage, the pressure fan blades rotate, causing the solvent and pressure additive to be pushed by the pressure fan blades during the solvent injection process, thereby improving the contact efficiency between the solvent, pressure additive and photovoltaic panel. When it is necessary to remove the solvent, the cleaning end inclined toothed cylinder drives the cleaning end sliding inclined toothed cylinder to rotate, thereby using the cleaning brush to continuously brush off the waste residue blocking the filter plate, preventing the waste residue from clogging the filter plate mesh. At this time, the pressure end inclined toothed cylinder drives the pressure fan blades to move back and forth through the inclined tooth structure, avoiding the rotation of the pressure fan blades during the discharge process, which would cause adverse interference to the discharge.
[0020] In this invention, when the cleaning brush rotates to the position of the spring rod, it will collide with the spring rod, thereby shaking the waste debris adhering to the brush head into the recycling box for recycling. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example: Refer to Figures 1-5 A waste photovoltaic panel dismantling and separation device includes a dismantling machine 1, a heating platform 2 installed on the dismantling machine 1, and a mechanical splitting platform 7 set on the rear side of the heating platform 2. A decomposition mechanism 3 is placed above the heating platform 2. The decomposition mechanism 3 includes a decomposition box 31. A locking door 32 is hinged to the rear side wall of the decomposition box 31. The rear side wall of the decomposition box 31 and the front side wall of the locking door 32 are respectively provided with mutually cooperating locking grooves and locking locks. Side mounting brackets 33 are fixedly connected to the bottom of both side walls of the decomposition box 31. A centering adjustment mechanism 4 is installed in the middle of the front side wall of the decomposition box 31. The centering adjustment mechanism 4 includes a centering cylinder 41. A connecting rod 42 is fixedly connected to the movable end of the centering cylinder 41. Drive wedge plates 43 are fixedly connected to the bottom two ends of the connecting rod 42. A centering plate 44 is connected to the two side mounting brackets 33 by springs. The drive wedge plate 43 cooperates with the wedge groove on the front side of the centering plate 44. A shovel plate 45 is fixedly connected to the middle of the front side wall of the connecting rod 42. The old photovoltaic panels to be dismantled are placed in the dismantling mechanism 3 for thermal decomposition. Before thermal decomposition, the locking door 32 is opened, and then the photovoltaic panels are placed into the dismantling box 31 from the rear side. The locking door 32 is then locked back into the rear side of the dismantling box 31 using a locking mechanism. The centering cylinder 41 is activated. When the centering cylinder 41 is activated, it drives the connecting rods 42 on both sides to drive the wedge plate 43 to move forward, which in turn drives the two centering plates 44 to move towards the center, thereby centering the photovoltaic panels. Then, the shovel plate 45 on the front side of the connecting rod 42 pushes the photovoltaic panels to move backward, so that the photovoltaic panels can accurately reach the target position of the dismantling box 31.
[0034] In an optional embodiment, a feed pipe 34 is fixedly connected to the middle of the right side wall of the decomposition box 31. The feed pipe 34 is used to inject organic solvent and pressure additive into the decomposition box 31, thereby simultaneously heating the photovoltaic panel on the heating platform 2 to perform thermal decomposition, which facilitates the separation of silicon wafers and glass.
[0035] In an optional embodiment: a solvent pressurizing mechanism 5 is installed on the outer wall of the feed pipe 34. The solvent pressurizing mechanism 5 includes a drive motor 51. A front baffle 511 is fixedly connected to the left end of the inner wall of the feed pipe 34. A drive shaft 53 is fixedly connected to the middle of the front baffle 511. A cleaning end toothed cone 54 and a pressurizing end toothed cone 514 are rotatably connected to the left and right sides of the outer wall of the drive shaft 53, respectively. A drive toothed cone 514 is fixedly connected to the movable end of the drive motor 51. 2. The drive tooth cone 52 meshes with the cleaning end tooth cone 54 and the pressurizing end tooth cone 514 respectively. The pressurizing end helical tooth cylinder 59 is fixedly connected to the right side wall of the pressurizing end tooth cone 514. The pressurizing fan blade 510 is slidably connected to the right end of the drive shaft 53. The pressurizing end sliding helical tooth cylinder 513 is fixedly connected to the left side wall of the pressurizing fan blade 510. The pressurizing end sliding helical tooth cylinder 513 and the pressurizing end helical tooth cylinder 59 cooperate with each other. A return spring 512 is sleeved between the pressurizing fan blade 510 and the front baffle 511. During the solvent injection stage, when the motor rotates in the forward direction, the pressure end tooth cone 514 rotates counterclockwise while the cleaning end tooth cone 54 rotates clockwise. At this time, the pressure end helical tooth cylinder 59 drives the pressure end sliding helical tooth cylinder 513 to rotate, which in turn drives the pressure fan blade 510 to rotate. This allows the solvent and pressure additive to be pushed by the pressure fan blade 510 during the solvent injection process, thereby improving the contact efficiency between the solvent, pressure additive and photovoltaic panel.
[0036] In an optional embodiment: a cleaning end inclined toothed cylinder 55 is fixedly connected to the left end of the cleaning end toothed cone 54, a cleaning end sliding inclined toothed cylinder 56 is slidably connected to the left end of the drive shaft 53, a filter plate 58 is fixedly connected to the left end of the drive shaft 53, a cleaning brush 57 is fixedly connected to the cleaning end sliding inclined toothed cylinder 56, and a spring is sleeved between the cleaning end sliding inclined toothed cylinder 56 and the filter plate 58. When the motor rotates in the forward direction, the pressure end toothed cone 514 rotates counterclockwise while the cleaning end toothed cone 54 rotates clockwise. At this time, the cleaning end inclined toothed cylinder 55 pushes the cleaning end sliding inclined toothed cylinder 56 forward through the inclined tooth structure, without causing the cleaning end sliding inclined toothed cylinder 56 to rotate, thereby reducing the contact time between the cleaning brush 57 and the filter plate 58 and avoiding unnecessary wear on the cleaning end sliding inclined toothed cylinder 56. When solvent needs to be removed, the motor rotates in the reverse direction. At this time, the pressure end toothed cone 514 rotates clockwise while the cleaning end toothed cone 54 rotates counterclockwise. At this time, the cleaning end inclined toothed cylinder 55 drives the cleaning end sliding inclined toothed cylinder 56 to rotate, thereby using the cleaning brush 57 to continuously brush off the waste residue blocking the filter plate 58, preventing the waste residue from clogging the mesh of the filter plate 58. At this time, the pressure end inclined toothed cylinder 59 drives the pressure fan blade 510 to move back and forth through the inclined tooth structure, avoiding the rotation of the pressure fan blade 510 during the discharge process, which would cause adverse interference to the discharge.
[0037] In an optional embodiment, a recycling mechanism 6 is detachably connected to the middle of the lower side wall of the feed pipe 34. The recycling mechanism 6 includes a recycling box 61, and a spring rod 62 is installed on the lower inner wall of the recycling box 61 via spring rubber. The spring rod 62 is used in conjunction with the cleaning brush 57. When the cleaning brush 57 rotates to the position of the spring rod 62, it will collide with the spring rod 62, thereby shaking the waste debris adhering to the brush head into the recycling box 61 for recycling.
[0038] Working principle: The old photovoltaic panels to be dismantled are placed in the dismantling mechanism 3 for thermal decomposition. Before thermal decomposition, the locking door 32 is opened, and then the photovoltaic panels are placed into the dismantling box 31 from the rear side. The locking door 32 is then locked back into the rear side of the dismantling box 31 using a locking mechanism. The centering cylinder 41 is activated. When the centering cylinder 41 is activated, it drives the connecting rods 42 on both sides to move the drive wedge plate 43 forward, which in turn moves the two centering plates 44 towards the center, thereby centering the photovoltaic panels. Then, the shovel plate 45 on the front side of the connecting rod 42 pushes the photovoltaic panels to the rear side. This allows the photovoltaic panel to accurately reach the target position in the decomposition box 31. Then, organic solvent and pressure additives are injected into the decomposition box 31, simultaneously heating the photovoltaic panel on the heating platform 2 to induce thermal decomposition, facilitating the separation of the silicon wafer and glass. During the solvent injection stage, when the motor rotates forward, the pressure end toothed cone 514 rotates counterclockwise while the cleaning end toothed cone 54 rotates clockwise. At this time, the pressure end helical toothed cylinder 59 drives the pressure end sliding helical toothed cylinder 513 to rotate, which in turn drives the pressure fan blade 510 to rotate. This ensures that during the solvent injection process, the solvent and pressure additives are separated by the pressure fan blade 510. 10. The motor drives the cleaning end inclined toothed cylinder 55 to move forward, thereby improving the contact efficiency between the solvent, pressurizing agent, and photovoltaic panel. At this time, the cleaning end inclined toothed cylinder 55 pushes the cleaning end sliding inclined toothed cylinder 56 forward through the inclined tooth structure, without driving the cleaning end sliding inclined toothed cylinder 56 to rotate. This reduces the contact time between the cleaning brush 57 and the filter plate 58, avoiding unnecessary wear on the cleaning end sliding inclined toothed cylinder 56. When solvent needs to be removed, the motor rotates in the reverse direction. At this time, the pressurizing end toothed cone 514 rotates clockwise and the cleaning end toothed cone 54 rotates counterclockwise. At this time, the cleaning end inclined toothed cylinder 55 drives the cleaning end sliding inclined toothed cylinder 56 to move forward. 6. Rotate the brush 57 to continuously brush off the waste residue clogging the filter plate 58, preventing the waste residue from clogging the mesh of the filter plate 58. At this time, the pressure end inclined tooth cylinder 59 drives the pressure fan blade 510 to move back and forth through the inclined tooth structure, preventing the pressure fan blade 510 from rotating during the discharge process and causing adverse interference to the discharge. When the cleaning brush 57 rotates to the position of the spring rod 62, it will collide with the spring rod 62, thereby shaking the waste debris adhering to the brush head into the recycling box 61 for recycling. After the solvent is completely discharged, the decomposition mechanism 3 is placed into the mechanical disassembly platform 7 for disassembly.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
