Description

Technical Field

[0001] This utility model relates to the field of renewable resource recycling, specifically to a sorting device for recycling broken photovoltaic glass. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. It mainly consists of three parts: photovoltaic modules, controllers, and inverters, with the main components being electronic devices. Photovoltaic modules are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as power controllers, this forms a photovoltaic power generation device.

[0003] The lifespan of photovoltaic (PV) modules is generally 25-30 years. However, product upgrades and replacements often shorten the actual lifespan of PV modules significantly from their designed lifespan. A large number of PV modules become obsolete due to performance failure or product upgrades. Simply crushing, burying, or incinerating these obsolete modules not only pollutes the environment but also wastes resources. Therefore, recycling PV module materials after their lifespan can alleviate the shortage of raw materials for PV devices to some extent and prevent environmental pollution.

[0004] Existing methods generally involve the decomposition and recycling of photovoltaic modules through high-temperature incineration and chemical treatment. High-temperature incineration softens and decomposes the EVA adhesive layer in photovoltaic modules under heating conditions, leaving recyclable materials such as glass, solder ribbons, and silicon wafers. These recyclable materials can be processed into different products through different processes. Therefore, recycling photovoltaic modules can yield a large amount of usable resources.

[0005] After photovoltaic modules are decomposed in the decomposition furnace, the resulting glass yields glass particles and powder of varying sizes. Since the recycled glass needs to be sold, mixing these different sized particles and powder not only reduces the value of the glass particles but also causes significant wear and tear on subsequent processing equipment if there is an excessive amount of powder. Therefore, separating the different sized glass particles from the glass powder is a current challenge. Utility Model Content

[0006] This invention provides a sorting device for recycling broken photovoltaic glass, which separates glass particles of different sizes from glass powder.

[0007] The technical solutions to the above technical problems are as follows:

[0008] A sorting device for recycling broken photovoltaic glass includes a fixed support, a housing, a damping spring, a vibrating motor, a first mounting base, a screen, and a discharge component. One end of the damping spring is connected to the fixed support, and the other end of the damping spring engages with the housing. The housing has an elongated cavity. The first mounting base is fixed to the bottom of the housing, and the vibrating motor is fixed to the first mounting base. The screen is located inside the housing and includes a large particle screen, a thick screen, and a powder screen. The powder screen, thick screen, and large particle screen are installed sequentially from bottom to top in the elongated cavity of the housing. The discharge component includes a first discharge component, a second discharge component, a third discharge component, and a fourth discharge component. The housing has a first output port that engages with the large particle screen, a second output port that engages with the thick screen, a third output port that engages with the powder screen, and a fourth output port located at the bottom of the housing. The first discharge component engages with the first output port and is fixed to the housing; the second discharge component engages with the second output port and is fixed to the housing; the third discharge component engages with the third output port and is fixed to the housing; and the fourth discharge component engages with the fourth output port and is fixed to the housing.

[0009] Furthermore, it also includes a dust cover, the housing having an opening and a feed inlet located on one side of the opening, with a large particle screen below the feed inlet, the dust cover engaging with the opening on the housing, and a lifting ring provided on the dust cover.

[0010] Furthermore, it also includes a feeding mechanism that pushes the powder at the bottom of the housing toward the fourth output port. Part of the feeding mechanism is located inside the housing, and another part of the feeding mechanism is located outside the housing. The side wall of the housing is provided with a clearance opening that cooperates with the feeding mechanism.

[0011] Furthermore, the feeding mechanism includes a linear drive assembly, a connecting rod, and a scraper. The linear drive assembly is located outside the housing. The end of the connecting rod passes through a clearance opening provided on the housing and is fixed to the linear drive assembly. The scraper is located inside the housing. One end of the scraper is fixed to the connecting rod, and the other end of the scraper engages with the inner bottom surface of the housing.

[0012] Furthermore, it also includes a baffle located inside the housing, the baffle cooperating with the clearance opening, one end of the first baffle being fixed to the housing, and the other end of the baffle being a free end.

[0013] In this invention, the vibrating motor generates a vibration force during operation, causing the material on the large particle screen to move. The large particle screen can separate large glass particles and other impurities, which are ultimately output from the first discharge component. Material passing through the mesh of the large particle screen falls onto a thickness screen, which can sieve the relatively suitable material according to the glass thickness to obtain glass within a first thickness range. This glass within the first thickness range is ultimately output from the second discharge component. The elongated mesh reduces clogging and facilitates cleaning. Material passing through the mesh of the thickness screen falls onto a powder screen, which can sieve the powder in the material. This powder within the second thickness range is ultimately output from the third discharge component, while glass powder falls through the mesh of the powder screen to the inner bottom surface of the housing, ultimately output from the fourth discharge component. As can be seen, this invention achieves the separation of glass particles of varying sizes from glass powder, significantly reducing the amount of glass powder in the first and second thickness ranges of glass, resulting in higher purity.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] like Figures 1 to 7As shown, the sorting device for recycling broken photovoltaic glass of this utility model includes a fixed support 1, a housing 2, a damping spring 3, a vibration motor 4, a first mounting base 5, a screen, and a discharge component. One end of the damping spring 3 is connected to the fixed support 1, and the other end of the damping spring 3 cooperates with the housing 2. The housing 2 has an elongated cavity. The first mounting base 5 is fixed to the bottom of the housing 2, and the vibration motor 4 is fixed to the first mounting base 5. The screen is located inside the housing 2. The screen includes a large particle screen 6, a thick screen 7, and a powder screen 8. The powder screen 8, the thick screen 7, and the large particle screen 6 are arranged sequentially from bottom to top in the elongated cavity of the housing 2. The installation includes a first discharge component 9, a second discharge component 10, a third discharge component 11, and a fourth discharge component 12. The housing 2 has a first output port that mates with the large particle screen 6, a second output port that mates with the thick screen 7, a third output port that mates with the powder screen 8, and a fourth output port located at the bottom of the housing 2. The first discharge component 9 mates with the first output port and is fixed to the housing 2; the second discharge component 10 mates with the second output port and is fixed to the housing 2; the third discharge component 11 mates with the third output port and is fixed to the housing 2; and the fourth discharge component 12 mates with the fourth output port and is fixed to the housing 2. The mesh openings 7a on the thick screen 7 are arranged along the length of the thick screen 7, i.e., the mesh openings 7a are elongated openings.

[0029] In this invention, the vibrating motor 4 generates a vibrating force when it operates, causing the material on the large particle screen 6 to move. The large particle screen 6 can separate large glass particles and other impurities, which are ultimately output from the first discharge component 9. The material passing through the mesh of the large particle screen 6 falls onto the thickness screen 7, which can screen the relatively qualified material according to the glass thickness to obtain glass within a first thickness range. The glass within the first thickness range is ultimately output from the second discharge component 10. The elongated mesh 7a reduces clogging and facilitates cleaning. Material falling through the mesh of the thickness screen 7 onto the powder screen 8, which filters out the powder in the material. The second thickness range of glass is finally output from the third discharge component 11, while the glass powder falls through the mesh of the powder screen 8 onto the inner bottom surface of the housing 2 and is finally output from the fourth discharge component 12. As can be seen from the above, this invention achieves the separation of glass particles of different sizes from glass powder, greatly reducing the amount of glass powder in the first and second thickness ranges of glass, thus making it more pure.

[0030] The device also includes a dust cover 13. The housing 2 has an opening and a feed inlet 2a located on one side of the opening. Below the feed inlet 2a is a large particle screen 6. The dust cover 13 fits into the opening on the housing 2 and is equipped with a lifting ring 14. During operation, the sorting device of this invention sorts glass, and since powdered glass is highly hazardous if inhaled, the dust cover 13 prevents the dust from escaping from the opening of the housing 2, thus reducing the harm to workers.

[0031] Because the glass powder itself has a very small particle size, the vibration force generated by the vibration motor 4 is difficult to move the glass powder that is far from the fourth output port into the fourth output port. Therefore, this utility model also includes a pushing mechanism that pushes the powder at the bottom of the housing 2 toward the fourth output port. A part of the pushing mechanism is located inside the housing 2, and the other part of the pushing mechanism is located outside the housing 2. The side wall of the housing 2 is provided with a clearance opening 2b that cooperates with the pushing mechanism.

[0032] The feeding mechanism of this utility model is an automatic feeding mechanism. Without stopping the machine, it can push the glass powder into the fourth output port and output it along the fourth discharge component 12 to avoid the glass powder from depositing at the bottom of the housing 2.

[0033] The feeding mechanism includes a linear drive assembly, a connecting rod 15, and a scraper 16. The linear drive assembly is located outside the housing 2. In this invention, the linear drive assembly includes a geared motor 18, a lead screw 19, and a nut 20. A support 2c is provided on the housing 2, and the geared motor 18 is mounted on the support 2c. The geared motor 18 is connected to the lead screw 19. A bearing assembly (not shown in the figure) is provided on the outer wall of the housing 2. The lead screw 19 passes through the bearing assembly and engages with it. The nut 20 is threadedly connected to the lead screw 19. A linear guide rail 2d is provided on the outer wall of the housing 2, and the nut 20 is slidably engaged with the linear guide rail 2d. The end of the connecting rod 15 passes through the clearance opening 2b provided on the housing 2 and is fixed to the linear drive assembly. In this embodiment, there are two sets of linear drive assemblies. Therefore, both ends of the connecting rod 15 are fixed to one nut 20. The scraper 16 is located inside the housing 2. One end of the scraper 16 is fixed to the connecting rod 15, and the other end of the scraper 16 engages with the inner bottom surface of the housing 2.

[0034] When it is necessary to push the glass powder to the fourth output port, the geared motor 18 is started to rotate forward. The output torque of the geared motor 18 drives the lead screw 19 to rotate. The lead screw 19 drives the nut 20 to move linearly along the linear guide rail 2d. The nut 20 drives the connecting rod 15 to move linearly. The connecting rod 15 drives the scraper 16 to move linearly towards the position of the fourth output port. The scraper 16 pushes the glass powder to the fourth output port.

[0035] Because a clearance opening 2b is provided on the housing 2, to reduce glass powder drifting out from the clearance opening 2b, this utility model also includes a baffle curtain 17 located inside the housing 2. The baffle curtain 17 cooperates with the clearance opening 2b. One end of the first baffle curtain 17 is fixed to the housing 2, and the other end of the baffle curtain 17 is a free end. The baffle curtain 17 can be made of cloth, rubber, or plastic. Since the connecting rod 15 moves in a straight line when it works, the connecting rod 15 pushes the baffle curtain 17 to float, meaning that the baffle curtain 17 does not affect the movement of the connecting rod 15.
