Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic pyrolysis, and in particular to a pyrolysis device for processing photovoltaic panels. Background Art

[0002] Photovoltaic modules are generally composed of aluminum frames, junction boxes, tempered glass, EVA film crystalline silicon cells and TPT backboards. Whole photovoltaic panels refer to the tempered glass panels (whole pieces), EVA film crystalline silicon cells and TPT backboards after the aluminum frames and junction boxes are separated from the photovoltaic modules.

[0003] The chain-plate pyrolysis device is the basis of photovoltaic pyrolysis. The existing chain-plate pyrolysis device includes a chain plate and an inlet and outlet, and the chain plate is located below the inlet. The existing pyrolysis device uses fuel (such as natural gas) or thermocouples to generate a high-temperature heat source to provide the energy required for pyrolysis to the entire pyrolysis device. The pyrolysis temperature is usually ≥500°C, and an inert gas (such as high nitrogen) is required as a carrier gas during the pyrolysis process. The purpose of pyrolysis is to volatilize the EVA that bonds the glass and silicon plates and the backplane after the assembly. Therefore, selecting a suitable pyrolysis temperature and the disposal form of the assembly, and quickly decomposing these two organic substances is a key factor in improving the assembly separation efficiency. The battery cells after pyrolysis will be collected through a collection bin. Usually, the collection bin will be set below the discharge end of the pyrolysis conveying chain plate, and the battery cells will fall from the pyrolysis conveying chain plate into the collection bin for collection. When the collection bin is full, the collection bin is taken out manually, the battery cells are unloaded, and then the empty collection bin is put back into the pyrolysis furnace. The operation is troublesome, and the high temperature in the pyrolysis furnace will also cause harm to the workers' health. Once the furnace door of the pyrolysis furnace is opened, the oxygen-free atmosphere in the pyrolysis furnace will be destroyed, affecting the pyrolysis effect. Summary of the invention

[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] The following describes a pyrolysis device for processing photovoltaic panels according to an embodiment of the present invention with reference to the accompanying drawings.

[0026] like Figure 1-3 As shown, an embodiment of the present invention proposes a pyrolysis device for processing photovoltaic panels, including: a pyrolysis unit and a collection vehicle 8, the pyrolysis unit includes a pyrolysis conveying chain plate 7 and a pyrolysis furnace 4, the pyrolysis conveying chain plate 7 is arranged inside the pyrolysis furnace 4, the pyrolysis conveying chain plate 7 has a feed end and a discharge end, the feed end of the pyrolysis conveying chain plate 7 is connected with the loading conveying chain plate 1, a radiation tube is provided in the pyrolysis furnace 4, and openable and closable gates 3 are respectively provided at the feed port and the discharge port of the pyrolysis furnace 4, and the discharge end of the pyrolysis conveying chain plate 7 is connected with the unloading conveying chain plate 6.

[0027] The collecting vehicle 8 is arranged below the discharge end of the pyrolysis conveying chain plate 7 to collect the battery cells after pyrolysis. The collecting vehicle 8 moves via a track connected to a plurality of carriages 9. The carriages 9 are provided with collecting vehicles 8 for alternate use. The side of the pyrolysis furnace 4 is provided with an openable and closable sealed door 12 for the collection vehicle 8 to enter and exit. The gate 3 and the sealed door 12 are respectively provided with a gas regulating device 2 to prevent the pyrolysis gas in the pyrolysis furnace 4 from overflowing.

[0028] The embodiment of the present invention sets up multiple collection vehicles 8, tracks and car compartments 9, so that the battery cells after pyrolysis fall into the collection vehicle 8 by their own weight. After a certain amount of battery cells are collected, the collection vehicle 8 is transported to the outside of the pyrolysis furnace 4 to complete the collection work, and then other unloaded collection vehicles 8 are transported to the pyrolysis furnace 4 to continue the collection, so as to achieve seamless alternating recovery of battery cells and avoid workers entering the high-temperature pyrolysis furnace 4 and causing harm to the workers. In addition, since the gas regulating device 2 is set up, the pyrolysis gas in the pyrolysis furnace 4 is prevented from overflowing, and the oxygen-free atmosphere in the pyrolysis furnace 4 is not destroyed, so the pyrolysis effect is guaranteed and the equipment utilization rate is improved.

[0029] Furthermore, the gas regulating device 2 includes a nitrogen source and a nozzle, the nozzle is connected to the nitrogen source through an injection pipe, and the nozzle is arranged in a row in the horizontal direction. By arranging the gas regulating device 2 at the gate 3, the pyrolysis gas in the pyrolysis furnace 4 can be prevented from overflowing from the furnace door, and the oxygen-free atmosphere in the pyrolysis furnace 4 can be prevented from being destroyed. The nozzle has an adjustable angle, an adjustable position, and an adjustable air pressure, which can prevent the gas in the furnace from overflowing to the greatest extent.

[0030] In some embodiments, Figure 3 As shown, the collecting vehicle 8 includes a collecting bin 81, a supporting plate 82, a driving mechanism and wheels. The collecting bin 81 is fixedly connected to the top of the supporting plate 82, the driving mechanism is arranged on the supporting plate 82, and the wheels are arranged at the bottom of the supporting plate 82. The driving mechanism drives the wheels to run on the track.

[0031] Furthermore, the driving mechanism is connected to a remote control system, and the operation of the collection vehicle 8 can be controlled by remote operation.

[0032] In some embodiments, an infrared sensor is provided on the inner wall of the collection bin 81 to monitor the height of the battery cells in the collection bin 81. The infrared sensor is connected to an alarm. When the battery cells in the collection bin 81 are accumulated to a set height, the alarm sounds an alarm. No manual observation is required, which improves convenience.

[0033] In some embodiments, Figure 3 As shown, a door 83 that can be opened and closed is provided on one side of the collecting bin 81, and the bottom of the collecting bin 81 is an inclined surface, which is inclined downward toward the door 83, so as to facilitate smooth discharge.

[0034] In some embodiments, Figure 3 As shown, the length of the support plate 82 is greater than the length of the collection bin 81, and a tilting block 84 is fixed to the support plate 82 at the outer side of the vehicle door 83. The upper side of the tilting block 84 is an inclined surface, and the inclination of the tilting surface of the tilting block 84 is equal to the inclination of the bottom of the collection bin 81. The inclined surface of the tilting block 84 is coplanar with the inclined surface of the bottom of the collection bin 81. When the vehicle door 83 is opened, the battery cells in the collection bin 81 are poured out of the collection vehicle 8 along the inclined surface of the tilting block 84. This is conducive to smoother discharge and avoids the battery cells from piling up on the edge of the support plate 82 during the discharge process.

[0035] In some embodiments, Figure 3 As shown, the length of the tilting block 84 is equal to the distance between the door 83 and the edge of the support plate 82. The lower end of the tilting block 84 is flush with the side of the support plate 82, so that the battery sheet can slide off the collection vehicle 8 quickly.

[0036] In some embodiments, Figure 1 As shown, the track includes a main track 11 and a branch track 10. A plurality of branch tracks 10 are provided and connected in parallel to the main track 11. The main track 11 extends into the pyrolysis furnace 4. A collection vehicle 8 is parked on each branch track 10. This facilitates the alternating operation of the collection vehicles 8. When a fully loaded collection vehicle 8 exits the pyrolysis furnace 4 to the corresponding compartment 9, an empty collection vehicle 8 in another compartment 9 starts and enters the pyrolysis furnace 4.

[0037] In some embodiments, Figure 1 As shown, two branch rails 10 are provided.

[0038] In some embodiments, Figure 2 As shown, the pyrolysis furnace 4 is in a "convex" shape, the middle position of the pyrolysis furnace 4 is raised upward to form a convex portion, the top of the convex portion is provided with an exhaust port 5, and the radiation tube is arranged at the position of the convex portion. It plays a certain preheating role in the photovoltaic panel feeding process and plays a slow cooling role in the discharging process, which can effectively prevent the glass plate from being broken due to a sharp temperature change.

[0039] In some embodiments, the exhaust port 5 is connected to a gas purification device so that the pyrolysis gas is discharged into the atmosphere after purification to avoid polluting the atmosphere.
