[0002] In the glass recycling industry, recyclable glass bottles, flat glass, and other raw materials are processed into materials with particle sizes within a certain range after crushing. However, during the recycling of waste glass, impurities such as metal, fabric scraps, and dust are often mixed in. After crushing the recycled glass, these impurities need to be removed. Moreover, different recycling methods have different requirements for the particle size of the crushed glass, necessitating the screening of glass fragments of different sizes. Therefore, a multi-stage vibrating screening device for waste glass is needed to meet the screening requirements of waste glass. Utility Model Content

[0006] In the aforementioned multi-stage vibrating screening device for waste glass, the width of the metal recycling bin is greater than the width of the inclined conveyor.

[0007] In the aforementioned multi-stage vibrating screening device for waste glass, the center lines of the first scanner, the magnetic stop signal transmitter, the second scanner, and the magnetic recovery signal transmitter are arranged parallel to the conveyor belt on the inclined conveyor.

[0008] The aforementioned multi-stage vibrating screening device for waste glass includes a coarse-grained screen and a fine-grained screen inside the screen box, spaced apart vertically.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] A multi-stage vibrating screening device for waste glass, such as Figures 1 to 3 As shown, the device includes an inclined conveyor 1, a screen box 3, and a controller. The screen box 3 is located below the discharge end of the inclined conveyor 1. A hopper 2 is located on the top of the screen box 3. High-strength electromagnets 7 are evenly distributed on the conveyor belt 6 of the inclined conveyor 1. Baffles are located on both sides of the high-strength electromagnets 7. An coded chip 8 with baffle number information is located on the outer side of the right baffle. A metal recycling box 5 is located below the inclined conveyor 1 behind the screen box 3. The width of the metal recycling box 5 is greater than the width of the inclined conveyor 1.

[0017] A first scanner 17 and a magnetic stop signal transmitter 15 are installed sequentially on the right side of the metal recycling bin 5 near the sieve box 3. A magnetic stop signal receiver 16 is provided on the left side of the metal recycling bin 5 opposite to the magnetic stop signal transmitter 15. The first scanner 17 is used to scan the coding chip 8 and obtain the corresponding number of the right side baffle.

[0018] The magnetic stop signal transmitter 15 and the magnetic stop signal receiver 16 work together to determine whether it is necessary to stop supplying power to the powerful electromagnet 7.

[0019] If the magnetic stop signal receiver 16 does not receive a signal, it means that the right side baffle is blocking the signal emitted by the magnetic stop signal transmitter 15. At the same time, the first scanner 17 obtains the baffle number information of the corresponding right side baffle coded chip 8 and sends a control signal to the controller to control the corresponding numbered strong electromagnet 7 to de-energize. At this time, the metal impurities adsorbed by the strong electromagnet 7 will fall into the metal recycling box 5 for collection.

[0020] On the right side of the metal recycling bin 5, away from the sieve box 3, a second scanner 20 and a magnetic recovery signal transmitter 18 are installed in sequence. On the left side of the metal recycling bin 5, opposite to the magnetic recovery signal transmitter 18, a magnetic recovery signal receiver 19 is provided. The second scanner 20 is used to scan the coding chip 8 and obtain the corresponding number of the right side baffle.

[0021] The magnetic recovery signal transmitter 18 and the magnetic recovery signal receiver 19 work together to determine whether it is necessary to restore the power supply to the high-power electromagnet 7 after the power failure.

[0022] If the magnetic recovery signal receiver 19 does not receive the signal from the magnetic recovery signal transmitter 18, it indicates that the right side baffle is blocking the magnetic recovery signal transmitter 18. At the same time, the second scanner 20 obtains the baffle number information of the corresponding coding chip 8 on the right side baffle and sends a control signal to the controller. If the number information scanned by the second scanner 20 is the same as the number scanned by the first scanner 17, the power electromagnet 7 with the corresponding number information is controlled to restore power supply and continue to move with the conveyor belt to perform the next adsorption of metal impurities.

[0023] The output terminals of the magnetic stop signal receiver 16 and the magnetic recovery signal receiver 19 are respectively connected to the input terminal of the controller, and the first scanner 17 and the second scanner 20 are respectively electrically connected to the controller.

[0024] The center lines of the first scanner 17, the magnetic stop signal transmitter 15, the second scanner 20, and the magnetic recovery signal transmitter 18 are set parallel to the conveyor belt 6 on the inclined conveyor 1.

[0025] The screen box 3 is equipped with a coarse-grained screen 11 and a fine-grained screen 13, which are arranged vertically and vertically. The screen box 3 is equipped with an upper discharge port 12 for discharging coarse glass residue from the coarse-grained screen 11 and a lower discharge port 14 for discharging fine glass residue from the fine-grained screen 13. The upper discharge port 12 and the lower discharge port 14 are staggered horizontally.

[0026] The screen box 3 is connected to the vibrating motor, and the controlled end of the vibrating motor is connected to the output end of the controller.

[0027] A blower pipe 10 is installed on the side wall of the screen box 3 above the coarse-grained screen 11. The blower pipe 10 is connected to a blower 4 on one side of the screen box 3. The controlled end of the blower 4 is connected to the output end of the controller.

[0028] An impurity recovery box 9 is provided on one side of the sieve box 3 opposite to the blow pipe 10, which is used to recover light impurities in the glass.

[0029] The method of using this utility model is as follows: First, the crushed waste glass is fed onto the inclined conveyor 1, and the high-powered electromagnet 7 is powered. During the conveying process, the metal impurities in the waste glass are attracted by the high-powered electromagnet 7. When the waste glass is conveyed to the discharge end, it is directly fed into the screen box 3 through the hopper 2. The screen box is vibrated by the vibrating motor, and the fan blows air to the upper part of the screen box to remove the light impurities in the waste glass. Then, the glass is screened through coarse and fine mesh screens.

[0030] Meanwhile, the powerful electromagnet 7, which adsorbs metal impurities, moves with the conveyor belt to below the inclined conveyor 1. When the magnetic stop signal receiver 16 does not receive a signal, it sends a signal to the controller, causing the first scanner 17 to scan the information of the coded chip 8 on the corresponding baffle and send the obtained baffle number information to the controller. Then, the powerful electromagnet 7 with the corresponding baffle number is de-energized, and the metal impurities fall into the metal recycling box for absorption.

[0031] As the conveyor belt continues to move, the magnetic recovery signal receiver 19 is blocked by the baffle. At this time, the second scanner 20 scans the coded chip on the baffle to obtain the corresponding baffle number information and compares it with the baffle number information scanned by the first scanner 17. If there is a baffle information with the same number, the power electromagnet 7 corresponding to the baffle number is restored to power, and then the above operation is repeated.

[0032] This invention provides a multi-stage vibrating screening device for waste glass. By installing powerful electromagnets on the conveyor belt of an inclined conveyor, metallic impurities in the waste glass are adsorbed. The waste glass is then screened in multiple layers through a screening box, effectively removing metallic impurities and achieving fine screening. Simultaneously, the coordinated operation of an encoding chip, a first scanner, a second scanner, a magnetic stop signal transmitter, a magnetic stop signal receiver, a magnetic recovery signal transmitter, and a magnetic recovery signal receiver allows the adsorbed metallic impurities to be collected into a metal recovery box when the conveyor reaches the bottom of the inclined conveyor. Power is then promptly restored to the powerful electromagnets to allow for the next round of metallic impurity adsorption as the conveyor belt moves. Furthermore, the use of a fan, a blower, and an impurity recovery box effectively removes lightweight impurities from the waste glass.
