Abstract
Description
Technical Field
[0001] The invention relates to the technical field of photovoltaic component recycling, and in particular to a high-temperature pyrolysis device for waste photovoltaic components. Background Art
[0002] The recycling process of retired photovoltaic modules can generally be divided into three steps: module disassembly, laminate dissociation, and component recovery. Among them, the "sandwich" structure (i.e., laminate) formed by the cells, glass, and backplane tightly fixed by ethylene-vinyl acetate copolymer (EVA) is difficult to disassemble, and the valuable components in photovoltaic modules are mainly concentrated in the laminate. At present, there are three main technical routes for the dissociation of laminates and the recovery of valuable components at home and abroad: physical method, chemical method, and thermal decomposition method. The thermal decomposition method is to decompose EVA in a high temperature environment to make it lose its adhesiveness, thereby destroying the tight structure of the laminate to achieve the dissociation of the components of the laminate.
[0003] Existing high-temperature pyrolysis devices for laminates can usually only separate the cells, glass, and backplane from each other. The ethylene-vinyl acetate copolymer (EVA) pyrolysis residues thereon cannot be directly removed, so further processing is required for recycling. This method greatly reduces the recycling efficiency of waste photovoltaic module laminates. At the same time, the existing pyrolysis devices have low pyrolysis efficiency, which will greatly waste heat energy, thereby increasing the pyrolysis cost.

[0032] As a preferred embodiment, the laminate to be pyrolyzed is input into the device through the laminate input belt 5, and the laminate is moved to the laminate pyrolysis cleaning component 3 through the corresponding component transfer component 4. The laminate pyrolysis cleaning component 3 will pyrolyze the laminate thereon twice, and after pyrolysis, the corresponding component (glass, backplane or battery cell) will be moved to a suitable position to remove ethylene-vinyl acetate copolymer (EVA) residues, and after the removal work is completed, it will be moved to the glass component output belt 6, the backplane component output belt 7 or the battery cell output belt 8 through the corresponding component transfer component 4.

[0033] Further, the laminate pyrolysis cleaning assembly 3 includes a laminate pyrolysis assembly 31, a glass component cleaning assembly 32, a back plate cleaning assembly 33, a battery cell cleaning assembly 34, a first moving assembly 35, and a second moving assembly 36, all of which are fixedly assembled on the upper surface of the middle carrier plate 2. The glass component cleaning assembly 32, the back plate cleaning assembly 33, and the battery cell cleaning assembly 34 are distributed around the laminate pyrolysis assembly 31, and the first moving assembly 35 is arranged between the glass component cleaning assembly 32 and the back plate cleaning assembly 33, and the second moving assembly 36 is arranged between the back plate cleaning assembly 33 and the battery cell cleaning assembly 34;
[0034] As a preferred embodiment, the laminate pyrolysis component 31 will perform two pyrolysis on the laminate thereon. After the first pyrolysis is completed, the glass component on the upper side of the laminate will be clamped and moved to the glass component cleaning component 32 through the first moving component 35. The glass component cleaning component 32 will remove and clean the ethylene-vinyl acetate copolymer (EVA) residues on the glass component, and then move it to the glass component output belt 6 through the corresponding component transfer component 4.

After the backplane cleaning component 33 and the battery cell cleaning component 34 remove and clean the ethylene-vinyl acetate copolymer (EVA) residues, they are moved to the backplane component output belt 7 and the battery cell output belt 8 through the corresponding component transfer component 4.

When the laminate is moved to the corresponding component clamping assembly 312 through the corresponding component transfer assembly 4, the component clamping assembly 312 will clamp the laminate. As the first rotating plate 311 rotates (counterclockwise), the laminate moves from the initial position (the position of the rightmost component clamping assembly 312) to directly below the first group of component heating assemblies 314. The component bearing assembly 313 under the group of component clamping assemblies 312 rises, and the component heating assembly 314 descends to heat the group of laminates. After the heating is completed (the ethylene-vinyl acetate copolymer between the glass and the battery cell is thermally decomposed), , the glass component is transferred by the first moving assembly 35, the first rotating plate 311 continues to rotate, and at the same time, the group of component clamping assemblies 312 will drive the deglazing laminate thereon to rotate 180°, and the deglazing laminate is moved to just below the second group of component heating assemblies 314, the component bearing assembly 313 below the group of component clamping assemblies 312 rises, and the component heating assembly 314 descends to heat the group of deglazing laminates. After the heating is completed (thermal decomposition of the ethylene-vinyl acetate copolymer between the backplane and the battery cell), the backplane component and the battery cell are transferred by the second moving assembly 36, and the first rotating plate 311 continues to rotate, so that the group of component clamping assemblies 312 return to the initial position.
[0037] Further, the component clamping assembly 312 includes a fixed bearing seat 3121, and two groups of fixed bearing seats 3121 are mirror-imaged and respectively fixedly embedded on both sides of the groove 315 opened on the first rotating plate 311.

[0038] As a preferred embodiment, the setting of two groups of bidirectional hydraulic cylinders 3123 and four groups of first unidirectional hydraulic cylinders 3124 can change the area between the four groups of clamping angles 3125, so that the component clamping assembly 312 can adapt to the clamping work of laminates of different sizes, and the setting of the first drive motor 3122 can make the laminates inside the group of component clamping assemblies 312 rotate, so that the laminates or components thereon can be adaptively rotated according to different operating steps, so that it can complete the pyrolysis work more efficiently.
[0039] Furthermore, the component bearing assembly 313 includes a fixed plate 3131, which is fixedly assembled on the lower ends of the two groups of fixed bearing seats 3121, and four groups of second one-way hydraulic cylinders 3132 are fixedly assembled on the upper surface of the middle part of the fixed plate 3131, and a closed bearing plate 3133 is horizontally fixedly assembled on the upper ends of the four groups of second one-way hydraulic cylinders 3132.

[0041] Further, the closed heating plate 3144, the closed carrying plate 3133, and the four sets of clamping angles 3125 can constitute a closed pyrolysis space;
[0042] As a preferred embodiment, when the component clamping assembly 312 drives the laminate thereon to the pyrolysis position, the four groups of second one-way hydraulic cylinders 3132 thereunder will extend, and at the same time the lifting plate 3142 will descend, and the closed heating plate 3144, the closed supporting plate 3133 and the four groups of clamping angles 3125 will form a closed pyrolysis space, and wrap the laminate therein. After the pyrolysis space is formed, the heater 3143 will continuously heat the pyrolysis space until ethylene-vinyl acetate copolymer (EVA) is pyrolyzed. The closed heating plate 3144, the closed supporting plate 3133 and the four groups of clamping angles 3125 are all heat-insulating structures, and the setting of the pyrolysis space can avoid heat waste to the greatest extent, thereby improving the pyrolysis efficiency and reducing the pyrolysis cost.
[0043] Further, the glass component cleaning assembly 32 includes a second rotating plate 321, which is horizontally fixedly assembled on the output shaft of the second motor, and the second motor is fixedly assembled on the upper surface of the middle bearing plate 2. The second rotating plate 321 is provided with four groups of grooves 315, in which the component clamping assemblies 312 are horizontally fixedly assembled, and the middle bearing plate 2 outside the second rotating plate 321 is fixedly assembled with a three-axis moving assembly 323 and a fixed bracket 325, and a wiping brush 324 is arranged on the three-axis moving assembly 323.

The cleaning agent box 327 is filled with a corresponding cleaning agent, and the cleaning agent should retain the properties of harmlessness, easy decomposition or easy volatility, thereby removing the residual film solvent on the component. In actual operation, the second motor is a stepping motor and rotates 90° each time. The initial position of the glass component cleaning component 32 is directly opposite to the cleaning nozzle group 326. When the first moving component 35 moves the separated glass component to the initial position, the component clamping component 312 at this location clamps the glass component, and the first moving component 35 returns to its initial position. At this time, the adhesive film surface of the glass component is located at the lower end, and the driving component clamping component 312 is rotated 180° to adjust the adhesive film surface of the glass component to the upper end, and then the second motor rotates 90° clockwise, and the three-axis moving component 323 drives the wiping brush 324 to wipe the surface of the glass plate, and continuously replenishes the adhesive film solvent on the wiping brush 324, so as to efficiently and conveniently remove the adhesive film on the surface of the glass component.
