Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic pyrolysis, and in particular to a continuous pyrolysis device for processing photovoltaic panels. Background Art

[0002] Photovoltaic modules are generally composed of aluminum frames, junction boxes, tempered glass, EVA film crystalline silicon cells and TPT backboards. Whole photovoltaic panels refer to the tempered glass panels (whole pieces), EVA film crystalline silicon cells and TPT backboards after the aluminum frames and junction boxes are separated from the photovoltaic modules.

[0003] The chain-plate pyrolysis device is the basis of photovoltaic pyrolysis. The existing chain-plate pyrolysis device includes a chain plate and a feed inlet and outlet, and the chain plate is located below the feed inlet. The existing pyrolysis device uses fuel (such as natural gas) or thermocouples to generate a high-temperature heat source to provide the energy required for pyrolysis to the entire pyrolysis device. The pyrolysis temperature is usually ≥500°C, and an inert gas (such as high nitrogen) is required as a carrier gas during the pyrolysis process. The purpose of pyrolysis is to volatilize the EVA that bonds the glass and silicon plates and the backplane after the assembly. Therefore, selecting a suitable pyrolysis temperature and the disposal form of the assembly to quickly decompose these two organic substances is a key factor in improving the separation efficiency of the assembly. However, some pyrolysis products will be attached to the glass plate after pyrolysis, which will affect the stacking and collection of the glass plate, and will also affect the later reuse of the glass plate.

The cylinder rod of the second transverse hydraulic cylinder is fixedly connected to the cylinder body of the second longitudinal hydraulic cylinder to drive the second longitudinal hydraulic cylinder to move in a horizontal direction perpendicular to the running direction of the glass plate 14, thereby driving the second motor and the second wire brush to move in the horizontal direction.

[0033] The first wire brush 75 and the second wire brush can move back and forth on the upper and lower surfaces of the glass plate 14 to clean repeatedly. The wire brushes can also be controlled to clean multiple times at designated locations to improve cleaning efficiency.

[0034] Furthermore, the output end of the first motor 73 is detachably fixedly connected to the first support plate 74 by bolts, and the output end of the second motor is detachably fixedly connected to the second support plate by bolts.

[0035] In some embodiments, Figure 3 As shown, the scraper device 9 also includes a third longitudinal hydraulic cylinder 91, a third support plate 92 and a scraper 93. The third longitudinal hydraulic cylinder 91 is provided with two and moves synchronously. The third longitudinal hydraulic cylinder 91 is arranged in the vertical direction. The cylinder rod of the third longitudinal hydraulic cylinder 91 is fixedly connected to the top of the third support plate 92 to drive the third support plate 92 to move in the vertical direction. The scraper 93 is detachably connected to the bottom of the third support plate 92.

[0036] Furthermore, the scraper 93 is fixedly connected to the third support plate 92 by bolts, so that the scraper 93 can be easily replaced.

[0037] In some embodiments, the scraper 93 is a wooden scraper. When scraping the glass plate 14, no damage is caused to the glass.

[0038] Furthermore, the angle formed between the tip of the scraper 93 and the upper belt surface of the unloading conveying chain plate 13 is an obtuse angle, which is convenient for scraping off the residual pyrolysis products.

[0040] In some embodiments, Figure 4 As shown, the two ends of the third support plate 92 extend out of the two sides of the upper belt surface of the unloading conveying chain plate 13, so as to facilitate the scraped residual pyrolysis products to be discharged outside the unloading conveying chain plate 13.

[0041] Furthermore, a receiving plate is provided below the unloading conveying chain plate 13 for receiving the scraped residual pyrolysis products.

[0042] In some embodiments, Figure 1 As shown, a transition roller 6 is provided between the pyrolysis furnace 4 and the second cleaning device 8, and the upper end surface of the transition roller 6, the upper belt surface of the pyrolysis conveying chain plate 11 and the upper belt surface of the unloading conveying chain plate 13 are all flush. The transition roller 6 plays a supporting role to prevent the pyrolysis conveying chain plate 11 from being too far away from the unloading conveying chain plate 13 and thus failing to transport the glass plate 14 to the unloading conveying chain plate 13.

[0043] Furthermore, a plurality of transition rollers 6 can be provided according to actual conditions.

[0044] In some embodiments, Figure 1 As shown, the pyrolysis furnace 4 is in a "convex" shape, the middle position of the pyrolysis furnace 4 is convex upward to form a convex portion, the top of the convex portion is provided with an exhaust port, and the radiation tube 5 is arranged at the position of the convex portion. It plays a certain preheating role in the photovoltaic panel feeding process and plays a slow cooling role in the discharging process, which can effectively prevent the glass plate 14 from being broken due to a sharp temperature change.

[0045] In some embodiments, Figure 1 As shown, a collecting bin 12 is provided below the discharge end of the pyrolysis conveying chain plate 11 to collect the battery cells after pyrolysis.

[0046] In some embodiments, Figure 1 As shown, a suction cup mechanism 10 is provided at the tail end of the unloading conveying chain plate 13 to unload the cleaned glass plate 14 from the unloading conveying chain plate 13 and stack and collect it.

[0047] Working process:

[0048] The whole photovoltaic panel is placed on the feeding conveying chain plate 1. The specifications of the chain plate can be determined according to the specifications of the photovoltaic panels to be processed. The specifications of the pyrolysis furnace 4 are determined according to the processing capacity. The feeding conveying chain plate 1 is driven to translate the whole photovoltaic panel into the pyrolysis furnace 4. The sealing gates 3 on both sides are closed to achieve a sealed state. Nitrogen is filled into the pyrolysis furnace 4 to form an oxygen-free atmosphere. The built-in radiation tube 5 of the pyrolysis furnace 4 is used to pyrolyze the photovoltaic panel. After the pyrolysis is completed, the sealed furnace doors on both sides are opened, and the gas regulating devices 2 on both sides are activated to prevent the pyrolysis gas in the furnace from overflowing after the sealed furnace doors are opened. The pyrolyzed glass plate 14 is translated to the unloading conveying chain plate 13, and the pyrolyzed battery cells are collected in the collection bin 12. At the same time, the photovoltaic panel on the feeding conveying chain plate 1 is translated into the pyrolysis furnace 4 for the next pyrolysis. The pyrolysis of multiple photovoltaic panels is completed in a cycle.

[0049] When the glass plate 14 that has completed pyrolysis is moved horizontally toward the lower material conveying chain plate 13, the first cleaning device 7 and the second cleaning device 8 are used to brush off the residual pyrolysis products on the upper and lower surfaces of the glass plate 14. Then, after being moved horizontally onto the lower material conveying chain plate 13, the scraping device 9 is used to scrape off the residual pyrolysis products on the top of the glass plate 14. The residual pyrolysis products below the glass plate 14 will naturally fall down at the first cleaning device 7 and the second cleaning device 8 due to their own gravity.
