Description

Technical Field

[0001] This utility model relates to the field of waste photovoltaic panel recycling technology, and in particular to a waste photovoltaic panel dismantling device. Background Technology

[0002] With the widespread application of photovoltaic (PV) panels, the disposal of waste PV panels has become a significant environmental issue. PV panels mainly consist of silicon wafers, glass, backsheets, and frames, with glass being one of the primary components. The glass in waste PV panels typically needs to be dismantled and recycled to reduce environmental impact. The equipment used for this dismantling is called a waste PV panel glass dismantling device. As the global installed capacity of PV power plants continues to increase, the recycling of decommissioned PV modules has become a crucial issue. In failed crystalline silicon PV modules, the binding force of EVA is the main contributing factor; breaking this force to separate the main components of the module is the core issue in recycling.

[0003] For example, the waste photovoltaic panel glass dismantling device disclosed in the authorization announcement number CN 222306833 U3 has obvious advantages in terms of stability, safety and efficiency, and can more effectively dismantle and process waste photovoltaic panels.

[0004] However, this does not solve the problem of the difficulty in damaging the EVA film during the existing dismantling process. Therefore, we propose a waste photovoltaic panel dismantling device. Utility Model Content

[0018] The embodiments of the present invention are described in detail below. 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 explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-4 As shown, this utility model provides a technical solution: A waste photovoltaic panel dismantling device includes a dismantling platform 1, a conveyor belt 4 movably arranged inside the dismantling platform 1, a plurality of limit bars 6 fixedly arranged outside the conveyor belt 4, a conveyor motor 7 fixedly arranged on one side of the dismantling platform 1, a connecting shaft 9 fixedly arranged on one side of the conveyor motor 7, an auxiliary frame 10 fixedly arranged above the dismantling platform 1, a cutting wire 14 fixedly arranged on one side of the auxiliary frame 10, a functional frame 15 fixedly arranged on one side of the auxiliary frame 10, and a laser heater 17 fixedly arranged inside the functional frame 15. In this embodiment, preferably, support legs 2 are fixedly installed at the four corners of the bottom of the disassembly table 1, and a connecting frame 3 is fixedly installed at one end of the disassembly table 1.

[0020] The above scheme uses a dismantling platform 1 to assist in the dismantling of photovoltaic panels. In this embodiment, preferably, the conveyor belt 4 is movably disposed on the side of the disassembly table 1 near the connecting frame 3, a conveyor shaft 5 is fixedly disposed inside the conveyor belt 4, and a plurality of limit bars 6 are fixedly disposed on the side of the conveyor belt 4 away from the conveyor shaft 5.

[0021] The above scheme uses conveyor belt 4 and limit bar 6 to stably transport waste photovoltaic panels.

[0022] In this embodiment, preferably, the conveyor motor 7 is fixedly installed on the side of the disassembly table 1 away from the conveyor belt 4, a protective box 8 is fixedly installed between the conveyor motor 7 and the disassembly table 1, and a connecting shaft 9 is fixedly installed between the conveyor motor 7 and the conveyor shaft 5.

[0023] The above scheme uses a conveyor motor 7 and a connecting shaft 9 to drive the conveyor belt 4 to roll, thereby completing the conveying work.

[0024] In this embodiment, preferably, the auxiliary frame 10 is fixedly installed on the outside of the conveyor belt 4 above the disassembly table 1, two auxiliary rollers 11 are fixedly installed inside the auxiliary frame 10, a cutting frame 12 is fixedly installed on one side of the auxiliary frame 10, a fixing plate 13 is fixedly installed inside the cutting frame 12, and two cutting wires 14 are fixedly installed on the inner side of the fixing plate 13. The above scheme uses an auxiliary frame 10, auxiliary rollers 11, a cutting frame 12, and a cutting wire 14 to further press and fix the photovoltaic panel, while also facilitating the cutting of the EVA film to disassemble the photovoltaic panel. In this embodiment, the functional frame 15 is fixedly installed on the side of the auxiliary frame 10 near the cutting frame 12, and an adjustment frame 16 is fixedly installed on the side of the functional frame 15 near the cutting frame 12. A laser heater 17 is fixedly installed at the bottom of the adjustment frame 16. The above scheme uses a laser heater 17 to heat the photovoltaic panel, soften the EVA film, and improve the disassembly speed.

[0025] Example 1: Workers can place the waste photovoltaic panels on the conveyor belt 4, and then use the limiting bar 6 to clamp and fix the photovoltaic panels. The height of the limiting bar 6 is slightly lower than the bottom layer of the photovoltaic panels. Then, the conveyor motor 7 drives the conveyor shaft 5 to rotate through the connecting frame 3, thereby driving the conveyor belt 4 to roll forward and move the photovoltaic panels towards the auxiliary frame 10. Then, the photovoltaic panels are cut by the cutting wire 14 set inside the cutting frame 12. The cutting wire 14 is located at the height of the EVA film connection of the internal components of the photovoltaic panel. The cutting wire 14 is made of nickel-chromium alloy wire and its diameter is smaller than the thickness of the EVA film. This allows workers to quickly disassemble the glass and other components of the photovoltaic panels.

[0026] Example 2: This device also uses auxiliary rollers 11 for clamping during the photovoltaic panel conveying process. Two auxiliary rollers 11 are set inside the auxiliary frame 10 to cooperate with the limit bar 6, thereby further fixing the photovoltaic panel during cutting. At the same time, a laser heater 17 is set inside the functional frame 15. The laser heater 17 heats the photovoltaic panel and softens the EVA film by heating, so that the cutting wire 14 can quickly cut the EVA film to disassemble the photovoltaic panel.

[0027] In this embodiment, a waste photovoltaic panel dismantling device is used such that workers place the waste photovoltaic panels above the conveyor belt 4, and then use the limiting bar 6 to clamp and fix the photovoltaic panels. The height of the limiting bar 6 is slightly lower than the bottom layer of the photovoltaic panels. Then, the conveyor motor 7 drives the conveyor shaft 5 to rotate through the connecting frame 3, thereby driving the conveyor belt 4 to roll forward and move the photovoltaic panels towards the auxiliary frame 10. Then, the cutting wire 14 set inside the cutting frame 12 cuts the photovoltaic panels. The cutting wire 14 is located at the EVA film connection point of the internal components of the photovoltaic panel. The device uses a cutting wire 14 to cut the EVA film at a height that allows workers to quickly disassemble the glass and other components of the photovoltaic panel. The advantages of this waste photovoltaic panel dismantling device include: the cutting wire 14 separates the glass and other components bonded by EVA film inside the photovoltaic panel; the conveyor belt 4 assists in transporting the photovoltaic panel; and the limiting bar 6 limits and fixes the photovoltaic panel. The photovoltaic panel is then conveyed forward by a conveyor motor 7, and the EVA film connecting the various components of the photovoltaic panel is cut by the cutting wire 14, allowing workers to quickly disassemble the waste photovoltaic panel. During the conveying process, auxiliary rollers 11 are used for clamping. Two auxiliary rollers 11 inside the auxiliary frame 10 cooperate with the limit bar 6 to further fix the photovoltaic panel during cutting. Simultaneously, a laser heater 17 is installed inside the functional frame 15 to heat the photovoltaic panel. By heating and softening the EVA film, the cutting wire 14 can quickly cut the EVA film to disassemble the photovoltaic panel. Another advantage of this waste photovoltaic panel disassembly device is that it is also equipped with a laser heater 17 to heat the photovoltaic panel, thereby softening the EVA film and facilitating the subsequent rapid cutting of the EVA film by the cutting wire 14 to quickly separate the various components inside the photovoltaic panel. At the same time, the device is also equipped with two auxiliary rollers 11 to cooperate with the limit bar 6 during cutting to further restrict the position of the photovoltaic panel.
