[0023] According to a first aspect of the invention, see Figures 1 to 9 This invention provides an integrated processing device for multi-layer photovoltaic modules, suitable for the efficient separation and recycling of resources such as aluminum frames, glass, silicon wafers, and solder ribbons from retired photovoltaic modules. Moreover, the processing device uses only green and inexpensive water to remove the EVA cross-linked structure from the photovoltaic panels, without involving potentially toxic chemical agents. The processing procedure has significant environmental advantages, meets environmental protection requirements, and provides a feasible solution for the resource utilization of photovoltaic equipment waste.

[0024] Specifically, the integrated processing equipment for multi-layer photovoltaic modules includes a main processing unit and supporting processing units; The main processing unit includes a main processing box 1, a photovoltaic panel support 2, a clamp-type arm 3, and a magnetic coupling rotator 4. The main processing box 1 has multiple layers of photovoltaic panel supports 2 spaced along its height, and each layer of photovoltaic panel supports 2 is used to place photovoltaic panels 8. Four magnetic coupling rotators 4 are respectively arranged around the box. One end of the clamp-type arm 3 is connected to the magnetic coupling rotator 4, and the other end is movably engaged with the aluminum frame 81 placed on the photovoltaic panel support 2. The magnetic coupling rotator 4 is used to drive the clamp-type arm 3 to move away from the photovoltaic panel 8 to remove the aluminum frame 81. The top of the main processing box 1 is provided with a water inlet 101 and a water outlet 102. The supporting treatment unit includes a pumping unit, the output end of which is connected to the water injection hole 101 for injecting high-pressure water into the main treatment tank 1. High-pressure water is injected into the main treatment tank 1 through the water injection hole 101 and flows out through the water outlet 102 to remove impurities, including dust, from the surface of the photovoltaic panel 8. High-pressure water is injected into the sealed main treatment box 1 through the water injection hole 101 and heated to a preset temperature to remove the EVA crosslinking structure of the photovoltaic panel 8, thereby achieving depolymerization and desorption of the adhesive film.

[0025] In this embodiment, the integrated treatment equipment and method for multi-layer photovoltaic modules integrates cleaning, EVA depolymerization, and aluminum frame 81 removal into a single main treatment unit, achieving fully automated, one-stop processing and significantly improving operational efficiency and space utilization. Furthermore, the EVA structure removal process employs hydrothermal depolymerization technology, using only water as the medium, avoiding the use of acids, alkalis, or harmful organic chemicals, reducing secondary pollution, and meeting environmentally friendly treatment requirements. In addition, the modular structure and standardized operating procedures of the treatment equipment can meet the future large-scale treatment needs of decommissioned photovoltaic modules.

[0026] For example, the pumping unit is used to pump a high-pressure water flow of 15-30MPa into the main treatment tank 1 to achieve high-speed flushing and cleaning of the surface of the photovoltaic panel 8.

[0027] Optionally, the integrated processing equipment for multi-layer photovoltaic modules also includes a temperature sensor 6 and a pressure sensor 7; The main treatment chamber 1 is equipped with the temperature sensor 6 and the pressure sensor 7; the temperature sensor 6 is used to detect the temperature inside the main treatment chamber 1, and the pressure sensor 7 is used to detect the pressure inside the main treatment chamber 1.

[0028] In the above embodiments, the temperature sensor 6 and pressure sensor 7 help to monitor the temperature and pressure inside the main treatment chamber 1 in real time, ensuring the stability and effectiveness of the photovoltaic module cleaning process and the removal process of the EVA crosslinked structure.

[0029] Optionally, the main treatment chamber 1 is provided with an air inlet 103 and an air outlet 104. The supporting treatment unit further includes a hot air drying unit, which is connected to the air inlet 103. The hot air drying unit is used to dry the interior of the main treatment chamber 1 with hot air to facilitate subsequent processing of the photovoltaic panels 8. The hot air drying unit is used at the end of the process to dry the residual moisture on the photovoltaic panel support 2 inside the main treatment chamber 1, with a drying temperature of 80-150°C.

[0030] Optionally, the supporting processing unit further includes a lifting unit, which is detachably connected to the photovoltaic panel support 2 and is used to lift the photovoltaic panel support 2 out of the main processing box 1 so as to sort the processed photovoltaic panels 8.

[0031] In the above embodiment, after the main treatment box 1 is cooled to room temperature, the lifting unit lifts the photovoltaic panel bracket 2 and sorts the materials to obtain reusable materials such as glass, solder strips, and silicon wafers. The operation is simple and achieves efficient separation and high-quality recycling of photovoltaic modules.

[0032] Optionally, the integrated processing equipment for multi-layer photovoltaic modules also includes a first flange 51 and a second flange 52; The main treatment box 1 is equipped with a first flange 51 and a second flange 52. The first flange 51 is provided with the water injection hole 101 and the air inlet hole 103; The second flange 52 is provided with the water outlet 102 and the air outlet 104.

[0033] In the above embodiments, the arrangement of the water inlet 101, air inlet 103, water outlet 102 and air outlet 104 is relatively simple, and at the same time it helps to quickly achieve the sealing of the main treatment box 1 by sealing each hole.

[0034] Optionally, the rotational speed range of the magnetic coupling rotator 4 is 0-1200 r / min, and the outward movement speed of the clamp-type arm 3 is 0-20 cm / s. This helps to stably control the clamp-type arm 3 through the magnetic coupling rotator 4, ensuring the stability of the outward movement of the clamp-type arm 3.

[0035] Optionally, the preset temperature is 230°C-330°C to achieve the depolymerization and removal of EVA adhesive in photovoltaic modules under high temperature and high pressure conditions.

[0036] In one specific implementation, the main processing unit is 3m long, 1.6m wide, and 1.5m high, and is designed to operate at a pressure range of 0-15MPa, thereby achieving efficient separation of photovoltaic modules.

[0037] In the embodiments of this application, see Figures 4 to 6 The clamp-type arm 3 includes a connecting post 31, a clamp 32, and a magnetic coupling link device 33. The magnetic coupling link device 33 is used to cooperate with the magnetic coupling rotator 4 to drive the clamp-type arm 3. The clamp 32 is used to engage with the latch 811 of the aluminum frame 81 to remove the aluminum frame 81.

[0038] For example, each magnetic coupling link device 33 corresponds one-to-one with a magnetic coupling rotator 4, and each magnetic coupling link device 33 is connected to multiple clamps 32 via connecting posts 31 distributed in the vertical direction. In the vertical direction, each clamp 32 corresponds to one layer of photovoltaic panel 8. See also Figure 6 In order to achieve more stable removal of the aluminum frame 81, in the horizontal direction, each side wall of the aluminum frame 81 of each photovoltaic panel 8 has a plurality of clamps 32.

[0039] In one specific implementation, see Figures 7 to 9The aluminum frame 81 is provided with a buckle 811 corresponding to the caliper 32. The buckle 811 and the caliper 32 are engaged to achieve a firm connection between the clamp arm 3 and the aluminum frame 81, thereby facilitating the removal of the aluminum frame 81.

[0040] According to a second aspect of the present invention, a method for integrated processing of multilayer photovoltaic modules is provided, employing the integrated processing equipment for multilayer photovoltaic modules as described in the first aspect, comprising the following steps: Step S1: Place the multi-layer photovoltaic panels 8 on the multi-layer photovoltaic panel bracket 2 respectively, and install the multi-layer photovoltaic panel bracket 2 into the main disposal box 1; Step S2: High-pressure water is injected into the main treatment tank 1 through the water injection hole 101 and flows out through the water outlet 102 to remove impurities from the surface of the photovoltaic panel 8; for example, the high-pressure water rinsing pressure is 15-30MPa and the rinsing time is 5 minutes. Step S3: High-pressure water is injected into the main treatment box 1 through the water injection hole 101 and the main treatment box 1 is sealed. The high-pressure water in the main treatment box 1 is heated to a preset temperature and maintained for 10-50 minutes to remove the EVA crosslinking structure of the photovoltaic panel 8. For example, during the removal of the EVA crosslinking structure, the water level in the main treatment box 1 is half the height of the main treatment box 1. Step S4: Activate the magnetic coupling rotator 4 to drive the clamp arm 3 to move away from the photovoltaic panel 8 to remove the aluminum frame 81 of the photovoltaic panel 8.

[0041] In the above embodiments, the integrated treatment method for multi-layer photovoltaic modules has a simple process and significant time and energy benefits. It only uses water to remove the EVA cross-linking structure in the photovoltaic panel 8 and does not involve chemical agents that are potentially toxic to the environment. The treatment process has obvious environmental advantages.

[0042] Optionally, the integrated processing method for multi-layer photovoltaic modules further includes: In step S5, condensate is injected into the main treatment tank 1 through the water inlet 101 and flows out through the water outlet 102 to cool the main treatment unit to room temperature. After the main treatment unit is cooled to room temperature, the cooling water is discharged. Step S6: Start the hot air drying unit to dry the interior of the main treatment chamber 1 with hot air. Step S7: Cool the main processing box 1 to room temperature, and lift the photovoltaic panel support 2 out of the main processing box 1 using the lifting unit, and sort and recycle the component materials on the lifted photovoltaic panel support 2.

[0043] The above embodiments help to achieve efficient separation and high-quality recycling of materials such as glass, silicon wafers, aluminum frames, and solder ribbons in retired photovoltaic modules.

[0044] Optionally, in step S3, the heating rate of the high-pressure water is no greater than 10℃ / min; The removal time for the EVA crosslinking structure of photovoltaic panel 8 is 10-50 minutes.

[0045] The above embodiments facilitate the efficient removal of EVA adhesive from photovoltaic modules.

[0046] In this embodiment, the integrated processing equipment and method for multi-layer photovoltaic modules overcomes the problems of low equipment integration, poor processing efficiency, difficulty in EVA removal, and heavy environmental pollution in existing photovoltaic module recycling processes.
