Description

Technical Field

[0001] The present application belongs to the field of photovoltaic module recycling equipment, and in particular, relates to a photovoltaic module glass panel recycling device. Background Art

[0002] Crystalline silicon photovoltaic modules are power generation devices that use crystalline silicon as a substrate to convert solar radiation into electrical energy through the photovoltaic effect. They are currently the most mainstream type of photovoltaic modules. The constituent materials of crystalline silicon photovoltaic modules contain materials with recycling value such as silver, aluminum, silicon, and glass. Some of these materials are recyclable in large quantities. In order to achieve the recycling of these materials, the research and development of scrapped photovoltaic panel recycling technology is of great significance.

[0003] The existing mainstream physical recycling process of photovoltaic modules includes the following steps. First, the wire box and aluminum frame of the photovoltaic module are removed by equipment. The remaining part is a laminate of EVA bonding glass, battery cells and backboard. The laminate is flattened and conveyed by multiple sets of rollers and the glass plate is removed by milling to form glass particles. After the glass is removed, it enters the crushing and sorting recycling equipment for sorting. When the glass plate of the photovoltaic module is recycled by milling, the milled glass is easy to accumulate at the cutter head and is difficult to be discharged in time, which affects the cutting effect of the cutter during the milling process. The glass particles accumulate to a certain height. The hardness and sharpness of the glass particles may cause damage to the battery cell layers; due to the accumulation of glass particles, it may be necessary to stop the machine more frequently for tool cleaning and replacement, which will lead to reduced production efficiency and increased production costs. The milling mechanism is arranged on the rear side of the pressure roller, and there is a problem that the laminate sags and is not flat due to its own gravity on one side of the pressure roller. The milling process causes part of the battery cell to be cut off or the whole cell to be damaged, resulting in the presence of fine battery cell particles in the separated glass particles, which need to be screened, which will increase the cost and process of recycling photovoltaic modules. It can be seen that the existing technology needs to be further improved and enhanced. Utility Model Content

[0004] The utility model provides a photovoltaic component glass panel recycling device, which at least solves or alleviates one or more technical problems in the prior art, or at least provides a beneficial option.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a photovoltaic assembly glass panel recycling device, including a double-roller conveying mechanism and a glass crushing and separation mechanism;

[0007] The double-roller conveying mechanism comprises an upper roller and a lower roller, and a flattening gap is provided between the upper roller and the lower roller for the laminate to pass through;

[0008] The glass crushing and separation mechanism includes multiple scrapers and a moving structure that can make the scrapers move back and forth along the width direction of the laminate. The scrapers are arranged in the forward direction of the laminate and are located below the glass surface of the laminate. The moving structure drives the scrapers to move back and forth to crush the glass panel and separate it from the battery cell surface of the laminate, and to throw off the glass particles attached to the scrapers to prevent accumulation.

[0009] The photovoltaic module glass panel recycling device of the utility model is provided with a scraper which moves back and forth along the laminate. After the glass panel of the laminate is flattened in a face-down posture through a flattening gap between an upper roller and a lower roller, the scraper contacts the glass panel, so that the glass panel is crushed by a lateral force and the glass panel is scraped off to form glass fragments and separate from the battery cells of the laminate. The glass particles falling on the scraper will be thrown away from the scraper as they repeatedly move lateraly, thereby preventing the accumulation of glass particles. The device can work continuously for a long time. Compared with milling, the process of scraping glass with a scraper is relatively simple, does not require complicated milling cutters and milling equipment, and has low equipment and tool costs.

[0010] In a preferred implementation, the scraper includes a blade head, and a blade and a material throwing portion are provided on the side of the blade head facing the glass panel. The blade contacts the glass panel to crush it, and some of the crushed glass particles fall into the material throwing portion and separate from the material throwing portion during the reciprocating movement of the scraper.

[0011] In a preferred implementation, the material throwing portion is a smooth arc-shaped surface, and the arc-shaped surface is arranged toward the glass panel.

[0012] A movable space is formed between the curved surface and the upper laminate, so that the glass particles are not squeezed but can be thrown out on both sides of the scraper as the scraper moves back and forth, thereby preventing the accumulation of glass particles and affecting the contact surface between the scraper and the glass panel, ensuring that the glass panel recycling can be carried out continuously, improving production efficiency and reducing production costs.

[0013] In a preferred implementation, the vertical projection of the cutter head falls into the vertical projection area of ​​the upper roller / lower roller.

[0014] The laminate can maintain a relatively straight posture when it moves forward a short distance after being flattened by the pressure roller. It can then contact the blade of the scraper for crushing and scraping while maintaining a relatively flat posture, thereby reducing the chance of the battery cell being damaged and removed, achieving higher quality glass recycling and reducing the subsequent screening workload.

[0015] In a preferred implementation, the surface of the blade head facing away from the glass panel is an inclined surface / arc surface.

[0016] The setting of the inclined surface or the curved surface enables the cutter head to be closer to the flattening gap and the lower roller, and the structural design is more reasonable.

[0017] In a preferred implementation, the horizontal distance between the double-roller conveying mechanism and the cutter head is adjustable.

[0018] In a preferred implementation, the flattening gap between the upper roller and the lower roller is adjustable.

[0019] The adjustable flattening gap setting can adapt to laminates of different sizes and thicknesses, thus achieving multiple uses of one machine.

[0020] In a preferred implementation, the scrapers are evenly spaced and arranged on a blade holder, the blade holder is connected to a moving structure, and the moving structure drives the blade holder to move back and forth to drive the scrapers to move back and forth.

[0021] In a preferred implementation, the blade seat is provided with a plurality of blade grooves arranged at intervals, the blade handle of the scraper is detachably arranged in the blade groove, clamping holes are provided between adjacent blade grooves, and clamping bolts are inserted into the clamping holes to fix adjacent scrapers.

[0022] The scraper is detachably connected to the blade holder through a clamping bolt structure, which is convenient for maintenance and replacement.

[0023] In a preferred implementation, a heating mechanism is also included. The laminate passes through the heating mechanism, the double-roller conveying mechanism and the glass crushing and separation mechanism in sequence. The heating mechanism can soften the adhesive material between the glass panel and the battery cell to facilitate separation. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

In the present invention, unless otherwise clearly specified and limited, a first feature being "upper" or "lower" than a second feature may be the first and second features directly contacting, or the first and second features indirectly contacting through an intermediate medium.

[0031] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0032] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0033] The utility model is described below in conjunction with the accompanying drawings.

[0034] The specific plans adopted are:

[0035] like Figure 1-2 As shown, the utility model provides a photovoltaic module glass panel recycling device, including a double-roller conveying mechanism 1 and a glass crushing and separation mechanism;

[0036] The double-roller conveying mechanism 1 comprises an upper roller 10 and a lower roller 11, and a flattening gap is provided between the upper roller 10 and the lower roller 11 for the laminate 4 to pass through;

[0037] The glass crushing and detaching mechanism includes a plurality of scrapers 20 and a moving structure 22 capable of reciprocating the scrapers 20 along the width direction of the laminate 4. The scrapers 20 are arranged in the forward direction of the laminate 4 and are located below the glass surface of the laminate 4. The moving structure 22 drives the scrapers 20 to reciprocate so that the glass panel is crushed and detached from the battery cell surface of the laminate 4, and the glass particles attached to the scrapers 20 are thrown off to prevent accumulation.

[0038] The photovoltaic module glass panel recycling device of the present invention is provided with a scraper 20 which moves back and forth along the laminate 4. After the glass panel of the laminate 4 is flattened in a face-down posture through a flattening gap between an upper roller 10 and a lower roller 11, the scraper 20 contacts the glass panel, so that the glass panel is crushed by a lateral force and the glass panel is scraped off to form glass fragments and separate from the battery cells of the laminate 4. The glass particles falling on the scraper 20 will be thrown away from the scraper 20 as they repeatedly move laterally, thereby preventing the accumulation of glass particles. The scraper 20 can work for a long time. Compared with milling, the process of scraping glass with the scraper 20 is relatively simple, does not require complicated milling cutters and milling equipment, and has low equipment and tool costs.

[0039] The specific implementation structure of the scraper 20 is shown in Figure 2 The scraper 20 includes a blade head 200, and a blade 2000 and a material throwing portion 2001 are provided on the side of the blade head 200 facing the glass panel. The blade 2000 can crush the glass panel when it contacts the glass panel during reciprocating movement. Some of the crushed glass particles fall into the material throwing portion 2001 and separate from the material throwing portion 2001 during the reciprocating movement of the scraper 20.

[0040] See also Figure 1 The scrapers 20 are evenly spaced apart on the blade holder 21, and the blade holder 21 is provided with a plurality of blade grooves 210 arranged at intervals. The blade handle 201 of the scraper 20 is detachably provided on the blade groove 210, and clamping holes 211 are provided between adjacent blade grooves 210. The clamping bolts 212 are inserted into the clamping holes 211 to fix the adjacent scrapers 20, thereby facilitating the replacement of the scrapers 20, facilitating the operation, and reducing the device cost.

[0041] See also Figure 2 The material throwing part 2001 is a smooth curved surface, which is arranged toward the glass panel. When the blade 2000 reciprocates to crush the glass panel, some glass particles come to the curved surface. Compared with the case where no curved surface is arranged, an activity space is formed between the curved surface and the upper laminate 4. The glass particles are not squeezed but can be thrown out on both sides of the scraper 20 under the reciprocating movement of the scraper 20, thereby preventing glass particles from accumulating and affecting the contact surface between the scraper 20 and the glass panel, ensuring that the glass panel recycling can be carried out continuously, improving production efficiency and reducing production costs.

[0042] The specific implementation structure of the mobile structure 22 is shown in Figure 1 , which is the prior art. Specifically, the moving structure includes a motor 121, a connecting rod 222, a first slide rail 213 arranged under the tool holder, and a first slider 220 cooperating with the first slide rail 213, referring to the reciprocating movement principle of the crank connecting rod 222. Of course, the moving structure 22 of the present application can also be a motor 121 screw, an electric push cylinder, etc., which can be selected according to actual needs.

[0043] In order to prevent the laminate 4 from contacting the cutter after sagging too much after passing through the pressing roller, thereby causing the battery sheet to be contacted by the cutter, in this embodiment, see Figure 2 , the vertical projection of the blade head 200 falls into the vertical projection area of ​​the upper roller 10 / lower roller 11, that is, the laminate 4 moves forward a short distance after being flattened by the pressure roller, and contacts the blade head 200 of the scraper 20 of the present application for crushing and scraping while maintaining a relatively good flat posture, thereby reducing the probability of the battery cell being damaged and removed, achieving higher quality glass recycling, and reducing the subsequent further screening work.

[0044] Furthermore, the side of the cutter head 200 facing away from the glass panel is an inclined surface / arc surface, so that the cutter head 200 can be closer to the flattening gap, and the structural design is more reasonable.

[0045] As a preferred embodiment of the present application, see Figure 1 The horizontal distance between the double-roller conveying mechanism 1 and the cutter head 200 can be adjusted. Specifically, the double-roller conveying mechanism 1 is provided with a base, and a second slider 13 is provided at the bottom of the base. The second slider 13 is arranged on the second slide rail 12. The double-roller conveying mechanism 1 is moved relative to the cutter head 200 by a driving mechanism, such as a motor 121, a lead screw, etc., so as to facilitate the adaptation and adjustment of photovoltaic modules of different sizes and thicknesses. After a laminated glass plate is completely removed, the double-roller conveying mechanism 1 can be moved away from the cutter head 200 to facilitate the removal of the laminated part with the glass removed, so as to prevent the laminated part from being damaged by the scraper.

[0046] As a preferred embodiment of the present application, the flattening gap between the upper roller 10 and the lower roller 11 can be adjusted to adapt to photovoltaic module laminates 4 of different sizes and thicknesses, achieving multi-purpose use of one machine. The specific adjustment structure is existing, see the illustrated structure, and this application will not repeat it.

[0047] As a preferred embodiment of the present application, it also includes a heating mechanism 3, and the laminated part 4 passes through the heating mechanism 3, the double-roller conveying mechanism 1 and the glass crushing and separation mechanism in sequence. Figure 1 A heating tube is provided in the heating mechanism 3, which is not shown in the figure. The heating temperature of the heating mechanism 3 is 150°C-200°C. The heating mechanism 3 can soften the adhesive material between the glass panel and the battery cell to facilitate the glass crushing and separation.

[0048] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0049] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
