Description

Technical Field

[0001] This utility model relates to the field of waste crystalline silicon solar cell recycling technology, and in particular to a waste crystalline silicon solar cell recycling device. Background Technology

[0002] Silicon solar cells are core components that use silicon wafers as substrates to directly convert sunlight into electrical energy through the semiconductor PN junction principle, and are also the main power generation component of solar panels. They are mainly divided into two categories: monocrystalline silicon and polycrystalline silicon. Monocrystalline silicon solar cells have high conversion efficiency and good stability but are more expensive, while polycrystalline silicon solar cells have a cost advantage but slightly lower efficiency.

[0003] Waste silicon solar cells still have high utilization value, but the surface of recycled silicon solar cells is usually covered with dust. The dust needs to be removed during recycling. Traditional manual dust removal is time-consuming and labor-intensive. Therefore, we have proposed a recycling device for waste crystalline silicon solar cells. Utility Model Content

[0004] The purpose of this invention is to provide a recycling device for waste crystalline silicon solar cells, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A recycling device for waste crystalline silicon solar cells includes a working box, a cleaning chamber, a moving platform, an electric push rod, a pushing rod, a connecting plate, a rotary motor, and a rotating plate. The cleaning chamber is located on the top of the working box, and the moving platform is located on the top of the cleaning chamber. An electric push rod is fixedly installed at the bottom of the moving platform, and a pushing rod is movably installed at the bottom of the electric push rod. A connecting plate is fixedly installed at the bottom of the pushing rod, and a rotary motor is fixedly installed at the bottom of the connecting plate. A rotating plate is fixedly installed at the bottom of the output end of the rotary motor.

[0006] The bottom of the rotating plate is fixedly equipped with a cleaning brush, and the inner walls of the working box are provided with rotating grooves on both sides, with a lead screw rotatably connected inside the rotating groove.

[0007] A servo motor is fixedly installed on one side of the rotating groove, and the output end of the servo motor is fixedly connected to the lead screw.

[0008] The lead screw has a threaded connection to a movable block on its outer surface, and the movable block is fixedly installed on both sides of the moving platform.

[0009] The inner wall of the work box has grooves on both sides, and a slider is slidably connected inside the groove. The slider is fixedly installed on both sides of the moving platform and is located below the moving block.

[0010] The working box contains a vibrating chamber, the bottom of which is fixedly fitted with a screen, and the bottom sides of which are fixedly fitted with vibrating motors and dampers.

[0011] The damper and the vibration motor are fixedly equipped with a support frame at their bottom. The support frame is fixedly installed on the inner wall of the working box. A collection box is fixedly installed at the bottom of the working box. The collection box is connected to the inside of the working box. Support legs are fixedly installed at the four corners of the bottom of the working box. A controller is fixedly installed on one side of the working box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This waste crystalline silicon solar cell recycling device, in the initial stage of waste crystalline silicon solar cell recycling, activates the cleaning components via a controller. A servo motor starts running, its output driving a lead screw inside a rotating groove to rotate. Since the lead screw is threadedly connected to moving blocks on both sides of the moving platform, and the sliders on both sides of the moving platform slide within the grooves to provide limiting and guiding functions, the rotation of the lead screw is converted into smooth horizontal movement of the moving platform. Simultaneously, an electric push rod extends at the bottom of the moving platform, pushing a connecting plate, a bottom rotating motor, and a rotating plate downwards. This causes the cleaning brush at the bottom of the rotating plate to contact the waste crystalline silicon solar cells in the cleaning chamber. Subsequently, the rotating motor drives the rotating plate and cleaning brush to rotate at high speed, thoroughly cleaning impurities on the surface of the solar cells, achieving preliminary cleaning of the solar cells. Compared to manual cleaning, this method saves time and labor.

[0013] 2. This type of waste crystalline silicon solar cell recycling system operates synchronously with the sweeping action. The controller activates the vibration motors on both sides of the vibrating chamber, which transmit vibrations to the chamber, causing it to vibrate continuously at high frequency. Under this vibration, lighter and smaller dust particles pass through the screen at the bottom of the chamber and fall directly into the collection box below. Larger and heavier waste crystalline silicon solar cells are trapped on the screen, achieving efficient separation of the cells and dust. During this process, dampers on both sides of the vibrating chamber absorb the impact of the vibrations, preventing severe vibrations from affecting the stability of the sweeping components and protecting the overall structure of the device. After the sweeping and vibration operations are completed, workers simply remove the clean solar cells from the screen inside the vibrating chamber, completing the entire recycling process. This ensures the purity of the recycled solar cells while achieving centralized collection of dust and impurities. Attached Figure Description

The cleaning chamber 2 is located on the top of the working box 1. The moving platform 3 is located on the top of the cleaning chamber 2. The electric push rod 4 is fixedly installed at the bottom of the moving platform 3. The pushing rod 5 is movably installed at the bottom of the electric push rod 4. The connecting plate 6 is fixedly installed at the bottom of the pushing rod 5. The rotary motor 7 is fixedly installed at the bottom of the connecting plate 6. The rotating plate 8 is fixedly installed at the bottom of the output end of the rotary motor 7.

[0018] The mobile platform 3 is responsible for carrying and moving the cleaning components. The bottom of the platform is fixed with an electric push rod 4. The two sides are connected to the lead screw 11 through the moving block 13 and the slider 15 cooperates with the slide groove 14. It can move smoothly in the horizontal direction under the drive of the servo motor 12, driving the cleaning brush 9 to cover the entire cleaning room 2 and achieve comprehensive cleaning.

[0019] The second embodiment of this application is as follows: Please see Figure 1 - Figure 4Based on the first embodiment, a cleaning brush 9 is fixedly installed at the bottom of the rotating plate 8. Rotating grooves 10 are formed on both sides of the inner wall of the work box 1. A lead screw 11 is rotatably connected inside the rotating groove 10. A servo motor 12 is fixedly installed on one side of the rotating groove 10. The output end of the servo motor 12 is fixedly connected to the lead screw 11. A moving block 13 is threadedly connected to the outer surface of the lead screw 11. The moving block 13 is fixedly installed on both sides of the moving platform 3. Sliding grooves 14 are formed on both sides of the inner wall of the work box 1. A slider 15 is slidably connected inside the sliding groove 14. The slider 15 is fixedly installed on both sides of the moving platform 3 and is located on the moving block. Below 13, a vibrating box 16 is movably installed inside the working box 1. A screen 17 is fixedly installed at the bottom of the vibrating box 16. Vibrating motors 18 are fixedly installed at the bottom of both sides of the vibrating box 16. Damperes 19 are fixedly installed at the bottom of both sides of the vibrating box 16. A support frame 20 is fixedly installed at the bottom of the dampers 19 and the vibrating motors 18. The support frame 20 is fixedly installed on the inner wall of the working box 1. A collection box 21 is fixedly installed at the bottom of the working box 1. The collection box 21 is connected to the inside of the working box 1. Support legs 22 are fixedly installed at the four corners of the bottom of the working box 1. A controller 23 is fixedly installed on one side of the working box 1.

[0020] The controller 23 is the core of the device. It is installed on one side of the work box 1 and is electrically connected to electrical components such as the servo motor 12, electric push rod 4, rotary motor 7, and vibration motor 18. The operator can issue commands through the controller 23 to adjust parameters such as the start, stop, speed, and lifting height of each component, so as to realize the automated control of the entire recycling process. At the same time, it can monitor the operating status of each component in real time to ensure the stable operation of the device.

[0021] In the initial stage of waste crystalline silicon solar cell recycling, the device activates the cleaning components via controller 23. Servo motor 12 starts operating, its output driving the lead screw 11 inside the rotating groove 10 to rotate. Since the lead screw 11 is threadedly connected to the moving blocks 13 on both sides of the moving platform 3, and the sliders 15 on both sides of the moving platform 3 slide within the groove 14, providing a limiting and guiding function, the rotation of the lead screw 11 is converted into smooth horizontal movement of the moving platform 3. Simultaneously, the electric push rod 4 at the bottom of the moving platform 3 extends, pushing the connecting plate 6 and the bottom rotating motor 7 and rotating plate 8 downwards. This causes the cleaning brush 9 at the bottom of the rotating plate 8 to contact the waste crystalline silicon solar cells in the cleaning chamber 2. Subsequently, the rotating motor 7 drives the rotating plate 8 and cleaning brush 9 to rotate at high speed, thoroughly cleaning impurities on the surface of the solar cells, achieving initial cleaning of the solar cells. Synchronous with the cleaning action, the controller 23 activates the vibration motors 18 on both sides of the vibration box 16. The vibration motors 18 transmit vibrations to the vibration box 16, causing it to vibrate continuously at a high frequency. Under the action of vibration, lighter and smaller dust particles pass through the screen 17 at the bottom of the vibration box 16 and fall directly into the collection box 21 below. Larger and heavier waste crystalline silicon solar cells are trapped on the screen 17, achieving efficient separation of solar cells and dust. During this process, the dampers 19 on both sides of the vibration box 16 absorb the impact force generated by the vibration, preventing severe vibration from affecting the stability of the cleaning components and preventing damage to the overall structure of the device. After the cleaning and vibration operation is completed, the staff only needs to remove the clean solar cells from the screen 17 inside the vibration box 16 to complete the entire recycling process, ensuring the purity of the recycled solar cells and achieving centralized collection of dust and impurities.
