Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel technology, specifically relating to an integrated machine for crushing and screening waste photovoltaic panels. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of thin-film solid-state photovoltaic cells made almost entirely of semiconductor materials. PV panels have no moving parts, allowing them to operate for extended periods without wear and tear. Simple PV cells can power watches and computers, while more complex PV systems can provide home lighting and supply electricity to the grid.

[0003] The lifespan of photovoltaic panels is typically around 25 years. As early installed photovoltaic panels gradually reach the end of their lifespan, and due to damage and upgrades caused by various reasons, the number of waste photovoltaic panels is constantly increasing. The long-term accumulation of waste photovoltaic panels occupies space and requires crushing. However, manual crushing of waste photovoltaic panels is slow, and the fragments are easily scattered and can cause injury to people in the vicinity. In addition, there is usually some adhesive film on the surface of the photovoltaic panels, which is inconvenient to clean. If it is not removed during crushing, it will enter the subsequent equipment with the crushed material, increasing the processing difficulty. Utility Model Content

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figure 1-5 This is the first embodiment of the present invention, which provides an integrated machine for crushing and screening waste photovoltaic panels, including...

[0031] The crushing assembly 100 includes a support 101, a housing 102 fixedly installed in the middle of the support 101, a main shaft 103 rotatably installed on the side wall of the housing 102, a cutter roller 104 fixed in the middle of the main shaft 103, and a first motor 105 fixed on the outside of the housing 102. The output shaft of the first motor 105 is fixedly connected to the main shaft 103.

[0032] The screening assembly 200 includes a roller 201 rotatably mounted on one side of the support 101, a guide plate 202 mounted on one end of the roller 201, and a hopper 203 disposed below the roller 201. The other end of the roller 201 is connected to the discharge port at the bottom of the housing 102. The side wall of the hopper 203 is connected to the support 101 by bolts.

[0033] The crushing component 100 is used to crush the photovoltaic panel. The crushed material enters the middle of the screening component 200 for screening. Large particles are discharged from the end of the roller 201 with the help of the guide plate 202 as the roller 201 rotates. Small particles fall below the roller 201 through the mesh on the side wall of the roller 201, separating them from the large particles at the front end, making it convenient to process the material separately. The power supply of the first motor 105 is turned on by the control equipment. The first motor 105 drives the main shaft 103 to rotate the cutter roller 104. The cutter roller 104 works with another set of cutter rollers 104 to crush the photovoltaic panel that enters the middle of the cutter roller 104. The crushed material enters the roller 201 from the bottom of the box 102.

[0034] Specifically, the screening assembly 200 also includes a driven sprocket 204 fixed to the outer wall of the roller 201, a second motor 205 installed at the middle position of the lower end of the bracket 101, a driving sprocket 206 fixedly installed at the end of the output shaft of the second motor 205, and a chain 207 adapted to be installed between the driven sprocket 204 and the driving sprocket 206.

[0035] A second motor 205 with a drive sprocket 206 is installed in the middle of the support 101. The end of the drive sprocket 206 is connected to the driven sprocket 204 on the side wall of the roller 201 via a chain 207. When the power supply of the second motor 205 is turned on by the control device, the second motor 205 will drive the roller 201 with the driven sprocket 204 to rotate through the drive sprocket 206 and the chain 207, so that the roller 201 rotates and rotates to screen the material inside the roller 201.

[0036] Preferably, the screening assembly 200 also includes a material box 208 installed at the bottom of the bracket 101, with the upper end of the material box 208 connected to the hopper 203.

[0037] The bottom side wall of the support 101 is added to connect with the hopper 203 to store the screened small particles and prevent the material from falling to the ground and causing pollution.

[0038] In use, the power supply to the first motor 105 is turned on by the control device. The first motor 105 drives the main shaft 103 to rotate the cutter roller 104. The cutter roller 104 works in conjunction with another set of cutter rollers 104 to crush the photovoltaic panels that enter the middle of the cutter rollers 104. The crushed material enters the roller 201 from the bottom of the box 102. The power supply to the second motor 205 is turned on by the control device. The second motor 205 drives the roller 201, which is equipped with a driven sprocket 204, to rotate through the drive sprocket 206 and the chain 207. The rotation of the roller 201 rotates and screens the material inside the roller 201. Small particles fall below the roller 201 through the mesh on the side wall of the roller 201, while large particles are discharged from the end of the roller 201 with the help of the guide plate 202 as the roller 201 rotates.

[0039] In summary, by using the crushing component 100 and the screening component 200 to crush and screen photovoltaic panels, various materials in waste photovoltaic panels can be effectively separated and recycled. After processing, relatively pure recyclables can be obtained, providing high-quality raw materials for subsequent resource reuse and greatly improving the resource recycling rate.

[0040] Example 2

[0041] Reference Figure 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a film removal component 300 for a waste photovoltaic panel crushing and screening integrated machine.

[0042] The membrane removal assembly 300 includes a feed pipe 301 installed on the top of the housing 102, a scraper 302 installed on the inner wall of the feed pipe 301, and a collection box 303 installed on the outer wall of the feed pipe 301.

[0043] The feed pipe 301 with a scraper 302 is installed on the top of the housing 102. The feed pipe 301 is used to guide the photovoltaic panel to be crushed, so that the photovoltaic panel can enter the crushing component 100 stably and prevent the photovoltaic panel from loosening. The scraper 302 is used to scrape off the residual adhesive film on the surface of the photovoltaic panel and guide the adhesive film to the collection box 303 for separate collection and treatment, thereby reducing impurities generated during the crushing process of the photovoltaic panel.

[0044] Specifically, the collection box 303 is connected to the through hole on the side wall of the feed pipe 301, and the lower end of the scraper 302 extends to the middle of the through hole on the side wall of the feed pipe 301.

[0045] The collection bin 303 is used to collect the film material scraped out by the scraper 302, reducing the amount of material entering the crushing component 100 along with the photovoltaic panel, and facilitating subsequent processing of the photovoltaic panel material.

[0046] Furthermore, the membrane removal assembly 300 also includes an air duct 304 installed on the inner wall of the feed pipe 301, an electric heating wire 305 installed inside the air duct 304, and a fan 306 installed at one end of the air duct 304.

[0047] The feed pipe 301 is equipped with a duct 304 containing a heating wire 305. The power supply to the fan 306 and the heating wire 305 is connected through a control component, and the operating parameters of the heating wire 305 and the fan 306 are adjusted. The fan 306 delivers gas into the duct 304. When the gas passes through the heating wire, it is heated by the heating wire 305, and then the hot air is blown towards the area above the scraper 302 to heat the photovoltaic panel in the middle of the feed pipe 301. This causes the adhesive film on the surface of the photovoltaic panel to shrink due to heat. The heat resistance temperature of the photovoltaic panel body is much higher than that of the adhesive film, so the photovoltaic panel body is not affected. When the photovoltaic panel body moves down, the scraper 302 scrapes off the adhesive film along the side wall of the photovoltaic panel, making it easier to guide the shrunken adhesive film into the collection box 303 for storage and separate transfer.

[0048] Preferably, the other end of the air duct 304 is positioned above the scraper 302, and the scraper 302 is symmetrically positioned above the cutter roller 104.

[0049] The air duct 304 is positioned above the scraper 302, which ensures that hot air is blown toward the photovoltaic panel. This ensures that the adhesive film on the surface of the photovoltaic panel has been heated and contracted when it passes the scraper 302, so that the adhesive film is stably scraped off by the scraper 302 to remove the film from the photovoltaic panel.

[0050] In use, the power supply to the fan 306 and the heating wire 305 is connected through the control component, and the operating parameters of the heating wire 305 and the fan 306 are adjusted. The fan 306 will deliver gas into the air duct 304. When the gas passes through the heating wire, it will be heated by the heating wire 305, and then the hot air will be blown to the area above the scraper 302 to heat the photovoltaic panel in the middle of the feed pipe 301. The adhesive film on the surface of the photovoltaic panel will shrink when heated and roll up on the surface of the photovoltaic panel. When the main body of the photovoltaic panel moves down, the scraper 302 will scrape off the adhesive film along the side wall of the photovoltaic panel and then scrape it off. The film will then enter the collection box 303 for storage along the scraper 302.

[0051] In summary, by installing a film removal component 300 on the top of the housing 102 to guide the photovoltaic panels that need to be crushed, the residual adhesive film on the surface of the photovoltaic panels can be scraped off and guided to the collection box 303 for separate collection and treatment, thereby reducing impurities generated during the photovoltaic panel crushing process.
