Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-8 The present invention provides a technical solution: a pyrolysis device for waste photovoltaic modules, comprising a pyrolysis box 1, which is placed on the floor of a production workshop. The interior of the pyrolysis box 1 is hollow, and a partition plate 15 is fixedly installed inside the box of the pyrolysis box 1. The partition plate 15 divides the interior of the pyrolysis box 1 into two areas, namely a preheating chamber 14 and a pyrolysis machine 2. A photovoltaic panel 5 is placed in the pyrolysis machine 2 for pyrolysis operation. The preheating chamber 14 is used to preheat the photovoltaic panel 5, which is convenient for staff to remove the backboard and prevent the backboard from releasing fluorine-containing substances during the pyrolysis process to pollute and harm the environment. Three groups of first cabinet doors 11 are hinged at one end of the outside of the pyrolysis box 1, which are located around the preheating chamber 14, so that the staff can observe the preheating state of the photovoltaic panel 5 and are convenient for daily maintenance. A second cabinet door 12 is hinged on one side of the preheating chamber 14, and a third cabinet door 13 is hinged on the other side.

[0029] The first cabinet door 11, the second cabinet door 12, and the third cabinet door 13 are all acrylic door panels made of transparent material, which is convenient for the staff to observe the preheating status of the photovoltaic panel 5;

[0030] Two groups of electric slide rails 151 are provided on one side of the partition plate 15, and a movable baffle 16 is slidably connected to the two groups of electric slide rails 151. Two groups of electric sliders 161 are fixedly installed on one side of the movable baffle 16. The two groups of electric sliders 161 cooperate with the two groups of electric slide rails 151. The movable baffle 16 is used to cooperate with the equipment program to control the outflow of hot air. A temperature sensor 4 is fixedly installed on the bottom of one side of the partition plate 15 for cooperating to detect the temperature in the preheating chamber 14. A camera 6 is fixedly installed on the top of one side of the partition plate 15 for cooperating to detect the position of the photovoltaic panel 5. The two groups of electric slide rails 151, the partition plate 15, and the camera 6 are all located in the preheating chamber 14;

[0031] The other end of the pyrolysis box 1 is hinged with a pyrolysis cabinet door 21, which corresponds to the position of the pyrolysis machine 2 and is used to assist the staff in placing the photovoltaic panels 5 that need to be pyrolyzed. It can also play a protective role. The pyrolysis machine 2 is equipped with a temperature detector (not shown in the figure) for detecting the temperature inside the box.

[0032] A clamping assembly 3 is also provided inside the pyrolysis box 1. The clamping assembly 3 includes a conveyor belt 31, a first slide rail 32, a first mobile mechanical claw 33, a second slide rail 34, and a second mobile mechanical claw 35. The conveyor belt 31 is placed on the floor of the production workshop, and one end of the conveyor belt 31 extends into the preheating chamber 14 in the pyrolysis box 1. The first slide rail 32 is fixedly mounted on the inner bottom surface of the preheating chamber 14. The first mobile mechanical claw 33 is slidably connected to the first slide rail 32. The claw of the first mobile mechanical claw 33 is longitudinally arranged to grab a photovoltaic panel 5 with a long length and a narrow width. The second slide rail 34 is fixedly mounted on the inner bottom surface of the preheating chamber 14, located on one side of the first slide rail 32. The second mobile mechanical claw 35 is slidably connected to the second slide rail 34. The claw of the second mobile mechanical claw 35 is transversely arranged to grab a photovoltaic panel 5 with a short length and a wide width.

[0033] The pyrolysis box 1 is connected to an external power source in the production workshop to provide electricity to drive the internal components to operate;

[0034] The pyrolysis box 1 is also equipped with an equipment program, which can control the opening and closing of the pyrolysis machine 2, the opening and closing of the conveyor belt machine 31, and the movement and stopping of the two sets of mobile mechanical claws;

[0035] The pyrolysis machine 2, the conveyor belt machine 31, two sets of mobile mechanical claws, the temperature sensor 4, the camera 6, the mobile baffle 16, and the built-in temperature detector of the pyrolysis machine 2 are all connected to the device program signal.

[0036] Preheating operation:

[0037] Before the pyrolysis operation is performed on the photovoltaic panel 5, the backboard of the photovoltaic panel 5 needs to be removed first to prevent the backboard from releasing fluorine-containing substances during the pyrolysis process, which may pollute and harm the environment. The staff first turns on the power in the workshop, starts the pyrolysis box 1, starts the equipment program, and controls the conveyor belt machine 31 to start. Then the staff places the photovoltaic panel 5 on the conveyor belt machine 31, and the conveyor belt machine 31 rotates forward to transport the photovoltaic panel 5 inward. The equipment program detects the size of the photovoltaic panel 5 through the camera 6. When it is necessary to clamp the photovoltaic panel 5 with a long length and a narrow width, During the preheating operation, the device program controls the first mobile mechanical claw 33 to extend downward to grab the photovoltaic panel 5, and after grabbing, it moves inward along the first slide rail 32 to the mobile baffle 16 and stops. When it is necessary to clamp and preheat the photovoltaic panel 5 with a short length and a wide width, the device program controls the second mobile mechanical claw 35 to extend downward to grab the photovoltaic panel 5, and after grabbing, it moves inward along the second slide rail 34 to the mobile baffle 16 and stops. The two sets of mobile manipulators can clamp and preheat photovoltaic panels 5 of different sizes at the same time;

[0038] When performing the above operations, the equipment program controls the preheating operation, the equipment program controls the pyrolysis machine 2 to start, the mobile baffle 16 extends upward along the electric slide rail 151, the equipment program sets the preheating temperature to M1, and the preheating time to T1, which can be modified according to specific production needs. During the preheating process of the pyrolysis machine 2, hot air will be blown out from the partition plate 15 to the photovoltaic panels 5 on the two groups of mobile mechanical claws, heating them so that the EVA film on the back of the photovoltaic panel 5 is softened by heat. When the T1 time is up, the equipment program controls the two groups of mobile mechanical claws to extend downward, and place the heated photovoltaic panel 5 on the conveyor belt 31, and then the equipment program controls the conveyor belt 31 to reverse and transport the photovoltaic panel 5 to the outside of the pyrolysis box 1. At this time, the staff can use tools to clamp the photovoltaic panel 5 to remove the back panel;

[0039] While the preheating operation is being performed, the equipment program detects the temperature in the preheating chamber 14 through the temperature sensor 4 and compares it with the set value. The equipment program sets the temperature value to H1, which can be adjusted according to specific production requirements. When the temperature value detected by the equipment program during the preheating process is less than H1, the equipment program does not operate. When the temperature value detected by the equipment program during the preheating process is greater than H1, the equipment program determines that the preheating time is long and the temperature in the preheating chamber 14 is high, which will affect the normal operation of the internal components. The equipment program sends an alarm signal to the staff, and the staff manually opens the second cabinet door 12 and the third cabinet door 13 to discharge the heat;

[0040] By using the pyrolysis machine 2, two sets of mobile mechanical claws and the equipment program in coordination, preheating can be performed before pyrolysis to reduce the time required for pyrolysis. During the preheating process, multiple photovoltaic panels 5 can be heated, and photovoltaic panels 5 of different sizes can be clamped for heating, so that the EVA film can be softened for easy removal by the staff, and the fluorine-containing substances in the back panel can be prevented from being discharged and polluting and harming the environment. By using the temperature sensor 4 in coordination with the equipment program, the temperature in the preheating chamber 14 can be detected during the heating and softening of the EVA film, so as to prevent heat from accumulating in the preheating chamber 14 when the preheating time is long, causing overheating and damage to other components, thereby reducing the maintenance cost of the factory.

[0041] Pyrolysis operation:

[0042] After completing the above operations, the staff performs the pyrolysis operation, and the equipment program controls the movable baffle 16 to close downward along the electric slide rail 151. After the staff manually opens the pyrolysis cabinet door 21, the dismantled photovoltaic panel 5 is placed in the pyrolysis machine 2 for pyrolysis operation. During the pyrolysis process, the equipment program detects the heating temperature through the built-in temperature detector of the pyrolysis machine 2 and compares it with the set value. The equipment program sets the heating temperature to 80°C and the moving value of the movable baffle 16 to X1, which can be modified according to production needs. When the pyrolysis operation starts, the equipment program controls the movable baffle 16 to rise upward, and the moving value is X1. The hot air in the pyrolysis box 1 will be discharged to the outside to avoid the photovoltaic panel 5 from being broken due to excessive heating rate, thereby improving the integrity of the photovoltaic panel 5 after the pyrolysis is completed. When the equipment program detects that the temperature in the pyrolysis machine 2 reaches 80°C, the equipment program controls the movable baffle 16 to close downward to perform subsequent high-temperature pyrolysis operations;

[0043] By using the movable baffle 16 in conjunction with the pyrolysis machine 2, the heating rate of the photovoltaic panel 5 can be controlled during the heating process to prevent the photovoltaic panel 5 from cracking due to an excessive heating rate, thereby improving the integrity of the photovoltaic panel 5 after the pyrolysis is completed. When the temperature reaches a specified temperature, the movable baffle 16 can be controlled to close, thereby ensuring the pyrolysis efficiency of subsequent high-temperature pyrolysis operations.
