Description

Technical Field

[0001] This invention relates to the technical field of crushing and separating waste photovoltaic panels, and specifically to a crushing and separating device for solar photovoltaic panels. Background Technology

[0002] Photovoltaic panels mainly consist of a glass panel and a backsheet. The backsheet is made of silicon wafers and can be reused. Similarly, the glass panel, after being broken, also has its value. Existing technologies also exist for separating and recycling photovoltaic panels, but their structures are too complex, their separation effect is poor, and their working efficiency is low.

[0003] A patent publication number CN117299277A was found, entitled "A Photovoltaic Panel Separation and Recycling Device," which specifically discloses a photovoltaic panel separation and recycling device. The device includes a housing with a feeding structure for pushing photovoltaic panels into the water, a crushing structure for breaking the photovoltaic panels, and a separation structure for impacting the broken panels. A driving structure drives the feeding, crushing, and separation structures. A screening structure for sieving the broken photovoltaic panels is also present on the housing. A hopper is provided on the housing. The crushing structure includes a second drive shaft, and two second drive shafts are rotatably mounted on the housing. Crushing rollers are fixed on the second drive shafts, and the two crushing rollers crush the photovoltaic panels. Gears are fixed on the second drive shafts, and the two gears mesh with each other. An anti-collision plate is inclinedly mounted on the housing, and protrusions are fixed on the anti-collision plate. A second sleeve drives a push plate to rotate, causing photovoltaic panel fragments on the push plate to be thrown towards the protrusions and the anti-collision plate.

[0004] A patent publication with publication number CN116237339A, entitled "A Recycling Device and Method for Photovoltaic Panels," was found. Specifically, a photovoltaic panel recycling device is disclosed, comprising a pushing component, a conveying component, a crushing component, a separating component, and a housing component. The housing component includes a housing, a base plate, and a slide, which are fixedly mounted on the base plate. The pushing component includes a side-sliding pusher and a supporting slide frame, with the side-sliding pusher slidably connected to the supporting slide frame, which is fixedly mounted on the housing. The conveying component includes conveying rollers and a conveying plate, both of which rotate. The glass is rotatably connected to the outer casing. The crushing assembly includes a drive wheel and crushing rollers. Multiple drive wheels are connected by belts and are rotatably connected to the outer casing. The crushing rollers are also rotatably connected to the outer casing and have sharp protrusions for crushing glass. The separation assembly includes a cutting blade and a sliding support plate. The cutting blade is slidably connected to the sliding support plate, which is fixedly installed on the outer casing. The outer casing on the photovoltaic panel is pushed away by a side sliding pusher. Then, the conveying roller is controlled to contact the photovoltaic panel and push it to move. After being bent by the drive wheel and crushed by the crushing rollers, the glass is separated by the cutting blade.

[0005] Analysis of the publicly available materials shows that the separation and recycling of photovoltaic panels can be achieved, but the structure is relatively complex and glass fragments on the back panel are prone to remain. Summary of the Invention

Figures 1 to 11 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0022] like Figures 1 to 11 As shown: Example

[0023] A crushing and separating device for solar photovoltaic panels includes a frame 1 and a conveying device. The conveying device includes a conveyor belt 2 mounted on the frame 1, a channel side plate 4 above the conveyor belt 2, and an upper cover 3 mounted on the frame 1 connected to the channel side plate 4. A crushing device includes a power roller 5 and a crushing roller 6 mounted at one end of the conveyor belt 2, with the power roller 5 positioned above the crushing roller 6 and a gap in between, through which the photovoltaic panel passes. A kneading device includes a fixed plate 7 mounted on the frame 1, a guide rod 20 mounted on the fixed plate 7, and an upper support plate 19 and a lower support plate connected to the guide rod 20.

[0024] In this embodiment, the frame 1 serves a supporting function. The frame 1 is a shell structure, and its interior also houses the electrical components necessary for the automated equipment. This technology processes waste photovoltaic panels after the junction box and frame have been removed. At this point, the photovoltaic panels have a back sheet and a glass panel. After passing through the equipment, the glass panel is broken into glass shards, and the back sheet is collected separately.

[0025] In this technology, a conveyor belt 2 is used to transport waste photovoltaic panels. A channel side plate 4 is set above the conveyor belt 2. The channel side plate 4 is distributed in a V shape to facilitate the adjustment of the conveying position of the waste photovoltaic panels. After passing through the outlet, the panels directly enter the crushing device.

[0026] The crushing device is equipped with a power roller 5 and a crushing roller 6. The power roller 5 is rotated by a second motor 21, which works with the crushing roller 6 to squeeze and convey the glass plate and crush it.

[0027] After the photovoltaic panel passes through the crushing device, glass shards will still stick to the back panel due to the presence of adhesive. At this time, a glass shard kneading device is needed. The kneading device is equipped with kneading plates 34, and kneading teeth are provided on the kneading plates 34. The glass shards are kneaded by the cooperation of the two kneading plates 34 swinging back and forth.

[0028] A receiving device is provided below the kneading device to collect broken glass shards, and a back plate collection rack 10 is provided above the kneading device. The processed back plates are conveyed to the back plate collection rack 10 for stacking.

[0029] To achieve efficient kneading, this technology also includes a kneading auxiliary device. The rotation of the first cam 30 drives the lower support plate to move up and down. The lower support plate and the upper support plate 19 are connected by a movable side plate 8. Therefore, the entire kneading device will also move up and down, thereby achieving efficient kneading of the glass shards on the back plate. Example

The frame 1 is equipped with a drive motor for driving the conveyor belt 2, and the conveyor belt 2 is a chain plate structure.

[0031] Unlike the above embodiments, in this embodiment, one end of the power roller 5 is connected to a reducer 22, and the other end is connected to a bearing seat through a bearing. The bearing seat is fixed on the frame 1. The frame 1 is also equipped with a drive motor for driving the conveyor belt 2. The conveyor belt 2 is a plate chain structure. Example

[0032] The crushing roller 6 is provided with a number of fixing rings 61, which are evenly spaced on the crushing roller 6 and fixed to the crushing roller 6. A fixing cone 62 is provided on the outer surface of the fixing ring 61. The fixing cone 62 is evenly spaced on the outer surface of the fixing ring 61 and protrudes outward. A crushing head 63 is provided on the fixing cone 62. The crushing head 63 is made of diamond and is used to crush the glass panel on the photovoltaic panel.

[0033] Unlike the above embodiments, in this embodiment, a fixing ring 61 is provided on the crushing roller 6. The fixing ring 61 is fixed to the crushing roller 6 through countersunk bolts. The fixing rings 61 are evenly spaced on the crushing roller 6. Since the glass on the photovoltaic panel has a certain hardness, a fixing cone 62 is provided on the fixing ring 61 to achieve initial crushing. A crushing head 63 is embedded in the fixing cone 62. The crushing head 63 is made of diamond, and the glass surface of the photovoltaic panel can be efficiently crushed by compression. In the above operation, the protective cover 9 provides protection. Example

[0034] The kneading device is equipped with a power mechanism. There are two rotating rods 31. The power mechanism includes a first sprocket 16 mounted on one of the rotating rods 31, which is connected to a first chain 15. It also includes a second sprocket 18 mounted on the other rotating rod 31, which is connected to a second chain 17. Both the first chain 15 and the second chain 17 are connected to a main sprocket 14. The main sprocket 14 is connected to a first motor 11 and is connected to the output end of the first motor 11 via a shaft. The first motor 11 is fixed on the upper support plate 19. The rotating rod 31 passes through the upper support plate 19 and the lower support plate, and is connected to the upper support plate 19 and the lower support plate respectively via bearings.

[0035] Unlike the above embodiments, in this embodiment, the kneading device has a power mechanism. There are two rotating rods 31, which are respectively set on the outer sides of both ends of the kneading plate 34. The top of one rotating rod 31 is provided with a first sprocket 16, which is connected to a first chain 15. The top of the other rotating rod 31 is provided with a second sprocket 18, which is connected to a second chain 17. The first chain 15 and the second chain 17 have a certain height difference in the vertical direction. Both the first chain 15 and the second chain 17 are connected to a main sprocket 14. There are two main sprockets 14. In order to ensure the stability of the main sprockets 14, they can be connected to the upper support plate 19 by rods and bearings. Example

[0036] There are two rubbing boards 34, both horizontally arranged, with a gap between them. The upper surface of each rubbing board 34 has several rubbing teeth, including a first rubbing tooth 35 and a second rubbing tooth 36. The cross-sectional shape of each rubbing tooth along the direction of the rubbing board 34 is a quarter circle arc, and the right angle surface is fixed to the upper surface of the rubbing board 34. The first rubbing tooth 35 and the second rubbing tooth 36 are arranged in opposite directions, forming a group of two, with a gap between adjacent groups, for rubbing off glass shards adhering to the back plate.

[0037] Unlike the above embodiments, in this embodiment, two kneading boards 34 are used and are set horizontally with a gap in the middle. The kneading teeth are quarter-circular arcs and right-angled surfaces are fixed to the upper end surface of the kneading board 34. Example

[0038] The third sprocket 27 is fixedly mounted on the outer shaft of the power roller 5. The auxiliary roller 29 is also provided with a sprocket that cooperates with the third chain 28. The auxiliary roller 29 is connected to the frame 1 through a bearing.

[0039] Unlike the above embodiments, in this embodiment, the power of the auxiliary roller 29 comes from the third chain 28, which is connected to the third sprocket 27. Therefore, the power comes from the first motor 11. Example

[0040] The glass shard receiving rack 13 is an inclined plate with a fixed plate 7 connected to its lower end by four rods, used to receive glass shards dropped from the crushing and kneading devices.

[0041] Unlike the above embodiments, in this embodiment, the glass receiving rack is used to receive glass shards dropped by the crushing and kneading devices. It is set at an angle, and a box can be placed below the outlet. Example

[0042] A pressing device is provided above the kneading device. The pressing device includes a fixed frame 23 set on the fixed plate 7. Several horizontally arranged pressing rollers 41 are provided on the fixed frame 23. Gaps are left between the pressing rollers 41. The pressing rollers 41 are used to press the back sheet on the photovoltaic panel.

[0043] Unlike the above embodiments, in this embodiment, when the photovoltaic panel is being rubbed in the rubbing device, several pressure rollers 41 are provided on the upper end face of the back plate. The pressure rollers 41, in conjunction with the rubbing device, can achieve efficient rubbing of glass slag. Example

[0044] The back plate collecting frame 10 is positioned above the pressure roller 41. The back plate collecting frame 10 has an L-shaped structure with a downwardly extending arc segment at the end. The two ends of the back plate collecting frame 10 are fixedly connected between the plate and the upper end face of the fixing frame 23.

[0045] Unlike the above embodiments, in this embodiment, the backplate collection rack 10 is used to collect the backplates after the glass shards have been removed, and the backplates can be stacked on the backplate collection rack 10. Example

[0046] A third motor 24 is installed on the fixed frame 23. The output end of the third motor 24 is connected to a roller brush 25. The roller brush 25 is a wire brush used to brush away residual glass shards from the back plate. The roller brush 25 is located diagonally below the steering roller 12.

[0047] Unlike the above embodiments, in this embodiment, after rubbing the back panel, some glass shards may remain on it. After brushing with a roller for 25 seconds, the glass shards are brushed off.

[0048] The working method (or working principle) of this invention: This technology operates in four stages: The first stage is the conveying of photovoltaic panels. After the junction box and frame are removed, the photovoltaic panels are placed on the conveyor belt 2 and conveyed by the conveyor belt 2 into the area below the upper cover 3. The lower end face of the upper cover 3 is fixedly provided with a channel side plate 4. The channel side plate 4 can adjust the conveying direction of the photovoltaic panels, so that the photovoltaic panels enter facing the direction of the power roller 5 and the crushing roller 6.

[0049] The second stage is preliminary crushing. After the photovoltaic panel is gripped by the power roller 5 and the crushing roller 6, if necessary, anti-slip textures can be set on the power roller 5. The combined action of the power roller 5 and the crushing roller 6 achieves the crushing of the glass panel. Several fixing rings 61 are set on the crushing roller 6, and a crushing cone is set on the fixing ring 61. A diamond-structured crushing head 63 is embedded on the crushing cone, which can achieve the preliminary crushing of the glass panel and cause some glass shards to fall off.

[0050] The third stage involves kneading the glass shards. Since the back plate is coated with adhesive, the glass shards are held together and need to be kneaded to remove them. The kneading device includes two kneading plates 34. These plates are connected to a second cam 32 via a connecting rod 33. The second cam 32 is connected to a rotating rod 31, which in turn connects to a first sprocket 16 and a second sprocket 18, and is powered by a second motor 21. The connecting rod 33 and the second cam 32 are connected by a pin, as are the kneading plates 34. The two kneading plates 34 move in opposite directions, employing a reciprocating kneading motion to remove the broken glass shards. To ensure stability during the kneading process, several rotating plates are arranged between the two kneading plates 34. The turning plate 39 and the kneading plates 34 are connected by a second connecting pin 40. The turning plate 39 is also provided with a first connecting pin 38, which connects to the support frame 37. The support frame 37 is provided with a fixed column, the lower end of which is connected to the lower support plate and fixedly connected to it.

[0051] The fourth stage is brushing off the glass shards. The roller brush 25 and the third motor 24 are used to brush off the remaining glass shards on the back panel. After being rubbed, the photovoltaic panel enters the position of the three guide rollers 12. One guide roller is located at the bottom, and the back panel moves upward after touching the guide roller 12. The two guide rollers at the top hold the back panel upward. The guide rollers 12 can be connected to the third motor 24 through a chain, and the third motor 24 can provide the power for collecting the material.

[0052] In this invention, unless otherwise explicitly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements or an interaction between two elements. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
