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.

[0021] The roller conveyor type pyrolysis device for processing photovoltaic panels according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 1-2 As shown, an embodiment of the present invention proposes a roller conveyor pyrolysis device for processing photovoltaic panels, comprising: a pyrolysis and decarbonization unit, a conveying roller 2, a silicon wafer collection box 8 and a glass collection box 10, the pyrolysis and decarbonization unit is suitable for pyrolysis and decarbonization of photovoltaic panels; the conveying roller 2 runs through the feed port and the discharge port of the pyrolysis and decarbonization unit, the conveying roller 2 is provided with a tray 1, the tray 1 is transmitted through the conveying roller 2, a first suction cup device 3 is provided upstream of the pyrolysis and decarbonization unit to place the photovoltaic panel on the tray 1 through the first suction cup device 3; the silicon wafer collection box 8 is provided downstream of the pyrolysis and decarbonization unit and is located on one side of the conveying roller 2, a blast device 11 is provided on the other side of the conveying roller 2, the blast device 11 is opposite to the position of the silicon wafer collection box 8 to blow the pyrolyzed silicon wafers on the tray 1 into the silicon wafer collection box 8; the glass collection box 10 is provided downstream of the silicon wafer collection box 8, and a second suction cup device 12 is provided downstream of the silicon wafer collection box 8 to place the pyrolyzed glass on the tray 1 into the glass collection box 10 through the second suction cup device 12.

[0023] The embodiment of the present invention solves the entire process of loading, pyrolysis, decarbonization and unloading of the entire photovoltaic panel in the form of a roller conveyor tray 1. The operation is simple and reliable, vibration is reduced, and the photovoltaic panel glass is effectively prevented from being broken due to the vibration of the material. By setting the first suction cup device 3 and the second suction cup device 12, the integrity of the photovoltaic panel during feeding and the integrity of the glass plate after pyrolysis are ensured, and the glass plate after pyrolysis can be completely collected. By setting the blowing device 11, the pyrolyzed silicon wafers can be blown into the silicon wafer collection box 8 by blowing, without the need to manually take out the silicon wafers, which is convenient for the collection of silicon wafers.

[0024] This device is a continuous pyrolysis device, which realizes loading, pyrolysis, decarburization and unloading by controlling the operation of the roller table, and realizes effective separation of pyrolysis products. The device is stable, reliable and easy to operate.

[0025] Furthermore, a baffle 13 is connected to the upper part of the back of the silicon wafer collection box 8 to prevent the silicon wafers from being blown off to the outside of the silicon wafer collection box 8 .

[0026] In some embodiments, the roller conveyor pyrolysis device for processing photovoltaic panels also includes a circulating track 9 and a rail car. The rail car is suitable for carrying empty pallets 1 after collecting glass. The circulating track 9 is arranged from the downstream end to the upstream end of the conveying roller 2. The rail car runs on the circulating track 9 from the downstream end to the upstream end of the conveying roller 2 to convey the empty pallets 1 to the upstream of the pyrolysis decarbonization unit.

[0027] By setting up a circulating track 9 and a rail car, it is convenient to place the empty tray 1 after pyrolysis of the photovoltaic panel on the rail car through the second suction cup device 12, and transport the tray 1 back to the roller conveyor in the loading area through the rail car, thereby realizing a closed loop of the entire process of the device.

[0028] In some embodiments, the pyrolysis decarburization unit includes a front gas replacement chamber 4, a pyrolysis chamber 5, a decarburization chamber 6 and a rear gas replacement chamber 7 which are connected in sequence, wherein the front gas replacement chamber 4 is connected to the inlet of the pyrolysis chamber 5, and the rear gas replacement chamber 7 is connected to the outlet of the decarburization chamber 6. By providing the front gas replacement chamber 4 and the rear gas replacement chamber 7, the problem of isolating the internal and external gases during pyrolysis and decarburization is solved, and external gas is prevented from entering the pyrolysis chamber 5 and the decarburization chamber 6 to affect the effects of pyrolysis and decarburization.

[0029] In some embodiments, a first sealed furnace door is provided at the entrance of the front gas replacement chamber 4, a second sealed furnace door is provided between the front gas replacement chamber 4 and the pyrolysis chamber 5, a third sealed furnace door is provided between the pyrolysis chamber 5 and the decarbonization chamber 6, a fourth sealed furnace door is provided between the decarbonization chamber 6 and the rear gas replacement chamber 7, and a fifth sealed furnace door is provided at the exit of the rear gas replacement chamber 7.

[0030] By respectively arranging sealed furnace doors at the inlets and outlets of the front gas replacement chamber 4, the pyrolysis chamber 5, the decarbonization chamber 6 and the rear gas replacement chamber 7, the atmosphere in the pyrolysis chamber 5 and the decarbonization chamber 6 can be protected from external gas contamination, thereby ensuring the effects of pyrolysis and decarbonization.

[0031] In some embodiments, the first suction cup device 3 includes a first mechanical arm and a first vacuum suction cup, and the operating end of the first mechanical arm is connected to the first vacuum suction cup. By using the first mechanical arm to control the first vacuum suction cup, it is convenient to transfer the photovoltaic panel from the stacking place to the pallet 1, reducing manual operation.

[0032] In some embodiments, the second suction cup device 12 includes a second mechanical arm and a second vacuum suction cup, and the operating end of the second mechanical arm is connected to the second vacuum suction cup. By using the second mechanical arm to control the second vacuum suction cup, it is convenient to transfer the pyrolyzed glass sheet from the tray 1 to the glass collection box 10, reducing manual operations.

[0033] In some embodiments, the air blowing device 11 includes an air duct, which is arranged in a horizontal direction and has a plurality of air outlets evenly distributed in the horizontal direction. By arranging a plurality of air outlets, the air outlet range is made wider and more uniform, and the situation where silicon wafers are left on the tray 1 is avoided.

[0034] Furthermore, the air duct is connected to a lifting device, and the height of the air duct can be adjusted so that the air outlet is aligned with the position of the tray 1 for blowing.

[0035] In some embodiments, the distance between the air outlets at both ends of the air duct is greater than the length of the tray 1, and the length of the silicon wafer collection box 8 is greater than the length of the air duct, so as to further improve the air outlet range, ensure that all silicon wafers are completely blown into the silicon wafer collection box 8, and prevent silicon wafers from falling outside the silicon wafer collection box 8.

[0036] In some embodiments, a rubber layer is connected to the bottom of the tray 1 to increase the friction between the tray 1 and the conveying roller 2 to prevent the tray 1 from slipping during the conveying process.

[0037] Furthermore, the rubber layer is made of high temperature resistant rubber material, and the temperature it can withstand is greater than the temperature required for pyrolysis and decarbonization of the photovoltaic panel.

[0038] In some embodiments, the upper end surface of the tray 1 is a horizontal surface, so that the contact surface between the photovoltaic panel and the tray 1 is a plane, which prevents the glass plate from breaking due to uneven force on the photovoltaic panel during the transmission process, and prevents the pyrolyzed silicon wafers from being left in the tray 1.
