Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically to a multi-stage screening machine for photovoltaic panel pyrolysis material with automatic unblocking function. Background Technology

[0002] A photovoltaic (PV) panel, also known as a solar photovoltaic panel, is a power generation device that uses solar cells as its core and is encapsulated with components such as glass, EVA film, and a backsheet. It utilizes the photovoltaic effect to directly convert solar energy into electrical energy. Its core function is to convert clean, renewable solar energy into directly usable electricity. PV panel pyrolysis material refers to the collective term for various recyclable materials separated and extracted from discarded PV panels through pyrolysis technology after the panels have reached the end of their service life. Its main components include pyrolyzed glass particles, metals, silicon materials, and pyrolytic resins.

[0003] A multi-stage screening machine for photovoltaic panel pyrolysis materials is a specialized device for particle size classification and screening of materials produced after photovoltaic panel pyrolysis. This equipment typically consists of a screen box, multiple layers of screens, a vibrator, and damping springs. Its working principle involves the vibrator generating vibrations, causing the material to undergo continuous throwing motion on an inclined screen surface. Particles smaller than the screen openings pass through and fall, achieving material classification. Its function is to efficiently and accurately classify glass particles, silicon powder, metal particles, and other materials in photovoltaic panel pyrolysis materials according to different particle sizes, providing high-quality materials for subsequent resource recycling.

[0004] However, considering that existing photovoltaic panel pyrolysis material multi-stage screening machines are in use, due to the different particle sizes of photovoltaic panel pyrolysis material, some materials with a size close to that of the screen mesh are easily stuck in the screen mesh during the screening process. As a result, after the screen has been working for a long time, the screen mesh will be too clogged, reducing the screening efficiency and screening effect of the multi-stage screening machine. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage screening machine for photovoltaic panel pyrolysis material with automatic unblocking function.

[0006] To achieve this objective, the present invention adopts the following technical solution: A multi-stage screening machine for photovoltaic panel pyrolysis material with automatic unblocking function is provided, including a support frame, a box, a screening mechanism and a buffer mechanism. The box is fixedly installed on the support frame, the screening mechanism is fixedly installed on the inner side of the box, the screening mechanism is used to screen the material, and the buffer mechanism is used to buffer the screening mechanism. The screening mechanism includes a frame, two sets of metal wires, two traction mechanisms, and a drive mechanism. The frame is slidably mounted on a buffer mechanism. One end of each set of metal wires is fixed to the frame, and the other end of each set penetrates the frame. The two sets of metal wires are distributed along the longitudinal and transverse directions of the frame, respectively. The two traction mechanisms are used to pull the two sets of metal wires, and the drive mechanism is used to move the two traction mechanisms. By using two sets of metal wires in different directions, the two sets of metal wires can perform screening when taut, and when relaxed, they can cause material stuck between the two sets of metal wires to fall off.

[0007] Furthermore, each traction mechanism includes a traction rod and a fixing plate. The fixing plate is fixedly installed on the frame, and a through groove is provided on the fixing plate. The traction rod is slidably installed on the inside of the through groove through a cylindrical rod, and the bottom of the traction rod is fixedly connected to the other end of the metal wire.

[0008] Furthermore, each traction mechanism also includes a movable block. A T-slot is provided on the frame, and the movable block is slidably mounted inside the T-slot. The movable block is hinged to the cylindrical rod via a hinged rod. The movement of the movable block drives the cylindrical rod and the traction rod to move, thereby tractioning the metal wire.

[0009] Furthermore, the drive mechanism includes threaded rod one and threaded rod two. Threaded rod one is rotatably mounted on the frame via a support plate and is threadedly connected to a moving block. Threaded rod two is rotatably mounted on the support plate and is threadedly connected to another moving block.

[0010] Furthermore, the drive mechanism also includes bevel gear one and bevel gear two. Bevel gear one is fixedly mounted on threaded rod one and fixedly connected, while bevel gear two is fixedly mounted on threaded rod two and meshes with bevel gear one. Through the meshing action of bevel gear one and bevel gear two, when threaded rod one rotates, it can drive threaded rod two to rotate, thereby simultaneously pulling the two sets of metal wires.

[0011] Furthermore, the drive mechanism also includes a motor, which is fixedly mounted on the frame, and the output shaft of the motor is fixedly connected to the threaded rod.

[0012] Furthermore, the buffer mechanism includes an L-shaped plate and a connecting rod. The L-shaped plate is fixedly installed inside the housing, and a guide groove is provided on the L-shaped plate. The frame is slidably installed inside the guide groove via a sliding rod. The connecting rod is fixedly installed on the sliding rod, and the connecting rod and the L-shaped plate are connected by a spring. Through the elastic force of the spring, a reaction force is generated on the connecting rod, thereby providing a buffering effect on the frame.

[0013] Furthermore, the buffer mechanism also includes a damper, which is fixedly mounted on the L-shaped plate, and the top of the damper is fixedly connected to the connecting rod. The damper slows down the movement speed of the connecting rod, reducing the impact force of the connecting rod on the spring and the L-shaped plate.

[0014] The beneficial effects of this utility model are as follows: This multi-stage screening machine for photovoltaic panel pyrolysis material with automatic unblocking function, through the setting of screening mechanism and traction mechanism, enables the traction rod to pull the metal wire, realizing the tensioning and relaxation effect of the metal wire. In this way, when the metal wire is relaxed, the blocked material will fall off, thereby improving the screening effect and screening efficiency of the multi-stage screening machine. In addition, through the setting of buffer mechanism, when the pyrolysis material falls onto the metal wire on the frame, it can generate a buffering effect, avoiding the metal wire from breaking or loosening due to excessive impact force, thereby further improving the service life and performance of the multi-stage screening machine.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0020] Reference Figures 1 to 3 The diagram shows a multi-stage screening machine for photovoltaic panel pyrolysis material with automatic unblocking function. It includes a support frame 1, a box 2, a screening mechanism 3, and a buffer mechanism 4. The box 2 is fixedly installed on the support frame 1. Pyrolysis material is poured into the box 2 for screening. The screening mechanism 3 is fixedly installed on the inner side of the box 2. The screening mechanism 3 is used to screen the material. Multiple screening mechanisms 3 are provided to enable multi-stage screening of pyrolysis material. The buffer mechanism 4 is used to buffer the screening mechanism 3, thereby reducing the impact force on the screening mechanism 3.

[0021] Reference Figure 2 and Figure 4Specifically, the screening mechanism 3 includes a frame 31, two sets of metal wires 32, two traction mechanisms 33, and a drive mechanism 34. The frame 31 is slidably mounted on the buffer mechanism 4. Multiple frames 31 are provided, and each frame 31 is provided with two sets of metal wires 32. The number of strands of the metal wires 32 on each frame 31 is different, so that the gap between the two sets of metal wires 32 on each frame 31 is different, thereby achieving the screening effect of pyrolysis material. One end of each set of metal wires 32 is fixedly mounted on the frame 31, and the other end of each set of metal wires 32 passes through the frame 31. By tightening the other end of the metal wires 32, the gap between the two sets of metal wires 32 can perform the screening function. When the other end of the metal wire 32 is relaxed, the gap between the two sets of metal wires 32 increases, causing the blocked material to fall off. The two sets of metal wires 32 are distributed along the longitudinal and transverse directions of the frame 31, respectively. By setting the two sets of metal wires 32 in different directions, pores for screening materials can be formed between the two sets of metal wires 32. The two traction mechanisms 33 are used to pull the two sets of metal wires 32, thereby causing the two sets of metal wires 32 to produce tension and relaxation. The drive mechanism 34 is used to drive the two traction mechanisms 33 to move. Through the setting of the drive mechanism 34, the two traction mechanisms 33 can be moved at the same time, thereby simultaneously causing the two sets of metal wires 32 to produce tension and relaxation effects.

[0022] Reference Figures 4 to 6 More specifically, each traction mechanism 33 includes a traction rod 331 and a fixing plate 332. The fixing plate 332 is fixedly installed on the frame 31, and a through groove 334 is provided on the fixing plate 332. The through groove 334 is used to guide the traction rod 331 and prevent the traction rod 331 from deviating when moving. The traction rod 331 is slidably installed on the inside of the through groove 334 through the cylindrical rod 333, and the bottom of the traction rod 331 is fixedly connected to the other end of the metal wire 32. Multiple metal wires 32 in the same direction are connected to the traction rod 331. Through the movement effect of the traction rod 331, multiple metal wires 32 in the same direction can be pulled to move simultaneously.

[0023] Reference Figure 5 and Figure 6 More specifically, each traction mechanism 33 also includes a movable block 336. A T-slot 337 is provided on the frame 31. The T-slot 337 is used to guide the movable block 336 and prevent the movable block 336 from deviating during movement. The movable block 336 is slidably installed on the inner side of the T-slot 337. The movable block 336 is hinged to the cylindrical rod 333 through the hinge rod 335. The movement of the movable block 336 can drive the hinge rod 335 to move, thereby driving the cylindrical rod 333 to move, so that the traction rod 331 moves.

[0024] Reference Figure 6 and Figure 7 Specifically, the drive mechanism 34 includes a first threaded rod 341 and a second threaded rod 344. The first threaded rod 341 is rotatably mounted on the frame 31 via a support plate 345, and is threadedly connected to a moving block 336. The rotation of the first threaded rod 341 can drive the moving block 336 to move, thereby driving a set of metal wires 32 to move. The second threaded rod 344 is rotatably mounted on the support plate 345, and is threadedly connected to another moving block 336. The rotation of the second threaded rod 344 can drive the other moving block 336 to move, thereby driving another set of metal wires 32 to move.

[0025] Reference Figure 6 and Figure 7 More specifically, the drive mechanism 34 also includes a first bevel gear 342 and a second bevel gear 343. The first bevel gear 342 is fixedly mounted on the first threaded rod 341 and fixedly connected. The rotation of the first threaded rod 341 drives the first bevel gear 342 to rotate. The second bevel gear 343 is fixedly mounted on the second threaded rod 344 and meshes with the first bevel gear 342. The rotation of the first bevel gear 342 drives the second bevel gear 343 to rotate, thus causing the second threaded rod 344 to rotate. The drive mechanism 34 also includes a motor 346, which is fixedly mounted on the frame 31. The output shaft of the motor 346 is fixedly connected to the first threaded rod 341. By starting the motor 346, the first threaded rod 341 can be driven to rotate.

[0026] Reference Figure 6 and Figure 8 Specifically, the buffer mechanism 4 includes an L-shaped plate 42 and a connecting rod 43. The L-shaped plate 42 is fixedly installed inside the housing 2, and a guide groove 44 is provided on the L-shaped plate 42. The guide groove 44 guides the frame 31 to prevent the frame 31 from shifting when moving. The frame 31 is slidably installed inside the guide groove 44 via a sliding rod 41. When the pyrolysis material falls onto the metal wire 32, it will impact the frame 31 and cause the frame 31 to move. The connecting rod 43 is fixedly installed on the sliding rod 41, and the connecting rod 43 is connected to the L-shaped plate 42 by a spring 45. The movement of the frame 31 will cause the sliding rod 41 and the connecting rod 43 to move, thereby compressing the spring 45. The elastic force of the spring 45 will generate a reaction force on the connecting rod 43, thereby buffering the frame 31. The buffer mechanism 4 also includes a damper 46, which is fixedly installed on the L-shaped plate 42, and the top of the damper 46 is fixedly connected to the connecting rod 43. The damper 46 is existing technology. When the frame 31 moves the connecting rod 43, the damper 46 can slow down the movement speed of the connecting rod 43, further improving the buffering effect on the frame 31.

[0027] Reference Figures 1 to 8 This multi-stage screening machine for photovoltaic panel pyrolysis material with automatic unblocking function, through its screening and traction mechanisms, enables the traction rod to pull the metal wire, achieving the tensioning and loosening effect of the metal wire. When the metal wire is loosened, the blocked material falls off, thereby improving the screening effect and efficiency of the multi-stage screening machine. Furthermore, the buffer mechanism provides cushioning when the pyrolysis material falls onto the metal wire on the frame, preventing excessive impact from causing breakage or loosening of the metal wire, thus further improving the service life and performance of the multi-stage screening machine.
