[0002] As the global energy structure shifts towards green and low-carbon development, the photovoltaic industry, as an important component of new energy, has experienced rapid growth in recent years. The scale of photovoltaic power plant construction continues to expand. However, during the basic construction process, a large amount of mixed waste, such as construction waste, waste packaging materials, metal components, and plastic film, is generated.

[0003] Currently, the methods for handling these construction wastes are generally quite extensive. On the one hand, most of them are simply mixed landfill or open-air dumping, which not only occupies valuable land resources, but also causes long-term pollution to soil and groundwater due to non-degradable substances such as plastic film. On the other hand, some use manual sorting in an attempt to recover valuable components, but this method is inefficient, labor-intensive, has poor sorting accuracy, and high labor costs, making it difficult to meet the construction needs of large-scale photovoltaic projects.

[0004] Therefore, in order to achieve convenient and reliable recycling of photovoltaic foundation construction waste, we propose a photovoltaic foundation construction waste recycling and treatment system. Summary of the Invention

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-6As an embodiment of the present invention, a photovoltaic foundation construction waste recycling and processing system is disclosed. Specifically, the processing system includes a frame 1 and a crushing mechanism 2 fixedly installed on the frame 1. The crushing mechanism 2 is used to crush the waste to facilitate subsequent centralized recycling operations. A film separation mechanism 3 and a solid extrusion mechanism 4 are fixedly installed inside the frame 1. The solid extrusion mechanism 4 is located below the discharge port of the crushing mechanism 2, and the film separation mechanism 3 is located between the crushing mechanism 2 and the solid extrusion mechanism 4. Inside the frame 1, there is a baffle 5 that blocks the discharge port of the crushing mechanism 2, and the frame 1 is equipped with a drive mechanism 6 that drives the baffle 5 to move.

[0021] In other words, the present invention, through the film separation mechanism 3 and the solid extrusion mechanism 4, can efficiently and accurately separate valuable components such as films and metals from mixed waste in photovoltaic construction waste, changing the inefficient mode of traditional manual sorting or mixed treatment and significantly improving the resource utilization rate of waste. Secondly, the solid extrusion mechanism 4 greatly reduces the storage and transportation volume of metals by extruding and molding them. By collecting the film separately, it avoids entanglement and pollution with other wastes. This pretreatment method makes the separated materials more in line with the requirements of downstream recycling companies and simplifies the subsequent reprocessing process.

[0022] In some embodiments, the crushing mechanism 2 of the present invention includes a crushing frame 21 fixedly installed on the frame 1. Two crushing rollers 22 are rotatably connected inside the crushing frame 21. The surfaces of the two crushing rollers 22 may be provided with crushing teeth or protrusions for applying shearing, squeezing and splitting action to the material when rotating relative to each other, thereby effectively crushing the waste fed therein. A motor 23 is fixedly installed above the frame 1. The shaft end of the motor 23 is fixedly connected to the shaft end of one of the crushing rollers 22. The shaft ends of the two crushing rollers 22 are meshed and driven by a synchronous gear 24.

[0023] Specifically, each of the two crushing rollers 22 has a meshing synchronous gear 24 fixed to its shaft end, forming a transmission pair. When the motor 23 drives one of the crushing rollers 22 to rotate, the power is transmitted to the other crushing roller 22 through the meshing transmission of the synchronous gear 24, forcing it to rotate synchronously in the opposite direction.

[0024] In a further embodiment, the solid extrusion mechanism 4 of the present invention includes; An extrusion frame 41 is fixedly installed inside the frame 1. An extrusion plate 42 is slidably connected inside the extrusion frame 41. An extrusion motor 43 is fixedly installed on the side of the extrusion frame 41. A crankshaft 44 is fixedly installed on the shaft end of the extrusion motor 43. A connecting rod 45 is pinned to the shaft end of the crankshaft 44. The other end of the connecting rod 45 is pinned to the extrusion plate 42.

[0025] Specifically, the extrusion frame 41 in this invention forms an extrusion cavity with an opening for accommodating the metal waste to be extruded. The extrusion motor 43 drives the crankshaft 44 to perform uniform circular motion. Since the two ends of the connecting rod 45 are respectively pin-connected to the crankshaft 44 and the extrusion plate 42, the rotational motion of the crankshaft 44 is converted into the reciprocating linear motion of the extrusion plate 42 in the extrusion frame 41 through the transmission of the connecting rod 45. When the extrusion plate 42 moves forward, it applies huge pressure to the metal waste in the extrusion frame 41, compacting it into a block. When the extrusion plate 42 moves backward, it makes room for the next loading and extrusion.

[0026] Based on the above embodiments, the driving mechanism 6 in this invention includes: A dual-axis motor 61 is fixedly installed in the frame 1 by a bracket. One end of the dual-axis motor 61 is connected to an upper gear 62. An opening is provided at the bottom of the frame 1. A guide rod 51 and an upper rack 52 are fixedly installed on the side of the baffle 5 and slide in the opening. The upper gear 62 and the upper rack 52 mesh and drive each other.

[0027] In this invention, the upper gear 62 is driven to rotate by the dual-shaft motor 61, which in turn drives the upper rack 52 to move. This causes the baffle 5 to move below the discharge port of the crushing frame 21, thus blocking the material and preventing it from falling further. Conversely, when the dual-shaft motor 61 drives the baffle 5 to move backward, the discharge port opens, and the material falls downward to the film separation mechanism 3 and the solid extrusion mechanism 4 for separation and collection.

[0028] In an optional embodiment, the shaft end of the dual-axis motor 61 of the present invention is slidably and circumferentially locked with a bushing 63. A lower gear 64 is fixedly installed on the end face of the bushing 63, and an upper gear 65 is fixedly installed on the shaft end of the upper gear 62. The lower gear 64 and the upper gear 65 are in contact. A spring 66 is fixedly connected between the bushing 63 and the shaft end of the dual-axis motor 61.

[0029] In actual operation, when the transmission force is within the preset normal range, the upper gear 65 and the lower gear 64 remain meshed under the elastic action of the compression spring 66, and the power can be transmitted normally. When the baffle 5 is blocked by an obstacle during the movement and cannot continue to move, but the dual-shaft motor 61 that drives it is still rotating and outputting torque, the meshing force between the gears will increase sharply. This increased force will overcome the elastic force of the compression spring 66 and push the lower gear 64 to move axially, so that the teeth of the upper gear 65 and the lower gear 64 disengage from each other. Once the gears disengage, the power transmission path is cut off, and there is no longer a transmission relationship between the upper gear 65 and the lower gear 64. At this time, although the dual-shaft motor 61 is still rotating, its power can no longer be transmitted to the baffle 5, thus effectively avoiding problems such as motor burnout caused by excessive torque. This design is also used to cooperate with the following skateboard 46 action. The specific principle will be described in detail later, and will not be elaborated here.

[0030] Based on the above embodiments, the bottom of the extrusion frame 41 in this invention is provided with a discharge port; A slide plate 46 is slidably connected to the bottom of the extrusion frame 41. An opening 47 adapted to the discharge port is provided on the end face of the slide plate 46. A transmission structure is provided between the slide plate 46 and the dual-axis motor 61.

[0031] Optionally, the transmission structure includes a lower rack 67 fixedly installed on the side of the extrusion frame 41, and a lower gear 68 fixedly installed on the other shaft end of the dual-axis motor 61, wherein the lower gear 68 and the lower rack 67 mesh and transmit power.

[0032] When the baffle 5 closes the discharge port, the slide plate 46 also moves, and the slide plate 46 closes the discharge port at the bottom of the extrusion frame 41. When the baffle 5 completely closes the discharge port, the extrusion motor 43 drives the crankshaft 44 to rotate, thereby driving the extrusion plate 42 to reciprocate linearly within the extrusion frame 41. The metal waste within the extrusion frame 41 is subjected to enormous pressure, which compresses the broken metal into blocks. At this time, because the slide plate 46 blocks the discharge port, the block material will not fall off. When it is necessary to unload the metal block, the dual-axis motor 61 mentioned above can be further activated. As described above, the baffle 5 can no longer move at this time, and the upper gear 65 and the lower gear 64 are separated. However, the dual-axis motor 61 can still drive the slide plate 46 to move until the opening 47 of the slide plate 46 is directly facing the discharge port at the bottom of the extrusion frame 41. Then the metal block falls downward, thus completing the unloading operation. Conversely, the dual-axis motor 61 drives each component to reset, in preparation for the next operation.

[0033] In some embodiments, the film separation mechanism 3 of the present invention includes a vertical plate 31 and a mounting base 32 fixedly mounted on the extrusion frame 41; A blower 33 is installed on the end face of the upright plate 31, and an exhaust fan 34 is installed on the end face of the mounting base 32. A collection frame 35 is slidably connected to the end face of the mounting base 32.

[0034] In this invention, a blower fan 33 and an exhaust fan 34 are used in combination to blow and exhaust the broken material from the screen. Since the film is lightweight, it will be blown into and collected in the collection frame 35. Preferably, the collection frame 35 is open on the side facing the blower fan 33, and a filter mesh 37 is provided on the side facing the exhaust fan 34. The suction force of the exhaust fan 34 can act on the inside of the collection frame 35 through the filter mesh 37, thereby firmly adsorbing the incoming film inside the frame and preventing it from being carried out by the subsequent airflow.

[0035] It should be noted that, in this embodiment of the invention, the bottom of the frame 1 is provided with a sliding groove 10, the bottom of the baffle 5 is fixedly installed with a locking pin 53 that slides in the sliding groove 10, and the side of the collection frame 35 is provided with a locking groove 36 that engages with the locking pin 53.

[0036] Specifically, in this invention, the locking pin 53 and the locking groove 36 are used to lock and position the collection frame 35. This invention adopts a linkage design with the baffle 5, that is, when the baffle 5 moves to close the discharge port, its movement will cause the locking pin 53 and the locking groove 36 to separate. At this time, the user can remove the collection frame 35 to pour out the film. With this design, online operation can be achieved without discharging material, which further improves the convenience and reliability of waste handling.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
