[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] like Figure 1 、 Figure 2 As shown, a screening device for recycling waste glass of the present invention comprises a dust removal component 2 and a screening component 4 , wherein the dust removal component 2 is arranged on the upper part of the screening component 4 .

[0021] The debris removal component 2 includes a plurality of debris separation mechanisms 21 , a rotating mechanism 22 and a fixing mechanism 25 . The plurality of debris separation mechanisms 21 are respectively connected to the fixing mechanism 25 , while the rotating mechanism 22 is slidably connected to the fixing mechanism 25 .

[0022] In this embodiment, a fixing mechanism 25 is disposed in the middle of the rotating mechanism 22, and a plurality of debris separation mechanisms 21 are evenly distributed on the fixing mechanism 25. During use, the rotating mechanism 22 is responsible for carrying the glass slag and, as it rotates continuously, evenly distributes the glass slag on the rotating mechanism 22. The debris separation mechanisms 21 detect the glass slag and separate impurities such as metal, stone, and ceramic from the glass slag, leaving only clean glass slag.

[0023] The screening component 4 is located below the impurity removal component 2 and is mainly responsible for screening the glass slag that has undergone impurity removal treatment.

[0024] The screening assembly 4 includes a separator plate 41 and a rotating column 42 . The separator plate 41 is mounted on the side wall of the rotating column 42 . The separator plate 41 is used to separate coarse and fine glass slag. The rotating column 42 is used to drive the separator plate 41 to rotate.

[0025] With the development of society, glass products have become an indispensable part of human life. At the same time, a large amount of glass waste is inevitably generated. Therefore, glass waste recycling has become crucial. The general process of glass waste recycling includes collection, classification, cleaning, crushing, sorting, reprocessing, and utilization. The particle size of the recycled glass slag needs to be limited. Larger glass slag requires secondary crushing before it can be used. The crushed glass slag often contains debris such as metal, stone, and ceramic. In actual production, most of the debris is manually sorted out and screened by vibration.

[0026] The screening device of the present invention places crushed glass slag on a rotating mechanism 22. As the rotating mechanism 22 rotates, the glass slag passes through a debris separation mechanism 21, where it detects and separates any impurities, such as ceramic pieces, metal pieces, or stones, from the glass slag. The design of multiple debris separation mechanisms 21 ensures a more thorough separation of impurities, preventing any omissions. This design not only improves impurity removal efficiency but also ensures the purity of the waste glass.

[0027] When the clean glass slag passes from the rotating mechanism 22 to the dividing plate 41, since the dividing plate 41 rotates along with the rotating column 42, the glass slag slides downward along the dividing plate 41 while the dividing plate 41 rotates. While sliding, the dividing plate 41 screens the glass slag of different particle sizes, thereby realizing the screening of the glass slag.

[0028] This design ensures that the particle size of the recycled glass slag is uniform, which facilitates subsequent processing.

[0029] At the same time, in this embodiment, the rotating column 42 can be set to rotate in reverse with variable frequency to better screen the glass slag.

[0030] like Figure 5 、 Figure 7 、 Figure 8 As shown, in some embodiments, the impurity removal component 2 also includes a first driver 23 and a plurality of collection bags 24. The first driver 23 is connected to the rotating mechanism 22 for providing rotational power for the rotating mechanism 22. The plurality of collection bags 24 are arranged in a one-to-one correspondence with the plurality of debris separation mechanisms 21, and can accurately capture and collect various types of separated impurities.

[0031] The fixing mechanism 25 includes a retaining ring 251, a baffle 252, and a discharge plate 253. The retaining ring 251 is fixedly connected to the debris separation mechanism 21 and provides stable support for it. The discharge plate 253 is welded to the bottom of the retaining ring 251 to facilitate the unloading of clean glass slag. The baffle 252 is welded to the retaining ring 251 and is positioned above the rotating mechanism 22 and is slidably connected to the rotating mechanism 22.

[0032] It should be noted that a discharge port 254 is provided on the retaining ring 251. One side of the discharge port 254 is connected to the baffle 252. A discharge plate 253 is provided below the discharge port 254. Specifically, during use, the rotating mechanism 22 rotates with the glass slag to the baffle 252. The baffle 252 effectively peels the glass slag from the rotating mechanism 22. The glass slag then falls through the discharge port 254 onto the discharge plate 253, thereby completing the process of sorting and screening the glass slag.

[0033] Furthermore, in some embodiments, the rotating mechanism 22 includes a rotating plate 221 and a first rack 222. The rotating plate 221 serves as the supporting component of the entire mechanism, primarily for supporting glass slag. The first rack 222 is disposed on the lower surface of the rotating plate 221 and welded thereto. The first rack 222 is connected to the first driver 23 via a gear transmission, providing power for the rotation of the rotating plate 221.

[0034] It is worth mentioning that the rotating plate 221 is made of transparent material.

[0035] In practice, when the first driver 23 is activated, it drives the first rack 222 through a transmission connection. The movement of the first rack 222, in turn, rotates the rotating plate 221. As the rotating plate 221 rotates, the glass slag is separated by the baffle 252. Furthermore, the transparent material of the rotating plate 221 facilitates the separation of debris from the glass slag.

[0036] Furthermore, in some embodiments, the debris separation mechanism 21 includes an air jet 211, a transmitter 212, and a receiver 213, which are respectively arranged in a corresponding manner. The air jet 211 is arranged on the retaining ring 251, the transmitter 212 is arranged on the upper portion of the rotating plate 221 and is fixedly connected to the retaining ring 251, and the receiver 213 is arranged on the lower portion of the rotating plate 221 and is fixedly connected to the retaining ring 251. The air jet 211 is used to eject high-pressure air and is connected to a high-pressure air pump.

[0037] Specifically, in this embodiment, the transmitter 212 is a laser transmitter, and the receiver 213 is a laser receiver. During use, the transmitter 212 emits a laser to the receiver 213. Since the glass slag and the rotating plate 221 are both transparent, if the laser signal received by the receiver 213 is complete, it means that the glass slag passing through the transmitter 212 is clean. If the laser signal received by the receiver 213 is missing, it means that the glass slag at the transmitter 212 contains impurities. In this case, the receiver 213 transmits a signal to the air jet 211, and the air jet 211 ejects high-pressure gas to separate the glass with impurities.

[0038] like Figure 2 、 Figure 4 As shown, in some embodiments, the screening assembly 4 further includes a support base 44, a second driver 45, and a fine material basket 46. The support base 44 serves as the foundation of the screening assembly 4 and supports and stabilizes the rotating column 42. The support base 44 is slidably connected to the rotating column 42, the lower portion of the rotating column 42 is connected to the fine material basket 46, and the second driver 45 is transmission-connected to the rotating column 42 via a second rack 43. The second driver 45 drives the rotating column 42 to rotate, thereby driving the distribution plate 41 to rotate, completing the screening of the glass slag.

[0039] The support base 44 includes a chute 441 and a support plate 442. The chute 441 is provided on the upper portion of the support plate 442 to provide a track for the sliding of the rotating column 42. The fine material basket 46 is provided on the lower portion of the support plate 442 so that the screened fine material can smoothly enter the fine material basket 46.

[0040] It should be noted that the second driver 45 serves as the power source of the screening assembly 4, providing a stable and reliable power output for the entire screening process. It is connected to the rotating column 42 through the second rack 43, and can adjust the rotation speed and direction of the screen as needed in actual use.

[0041] The screening assembly 4 achieves efficient and accurate screening of glass waste through the ingenious configuration and cooperation of components such as the support base 44, the second drive 45 and the fine material basket 46.

[0042] Furthermore, in some embodiments, the rotating column 42 includes a column housing 421, multiple fine material discharge ports 422, and a slider 423. The column housing 421 not only provides a sturdy structural support for the entire rotating column 42, but also features a hollow structure and multiple fine material discharge ports 422 defined on its sidewalls, providing a convenient outlet for the screened fine material. The slider 423 is cleverly positioned at the end of the column housing 421, slidably connected to the chute 441, thereby ensuring stability and precision during the rotation of the rotating column 42. The second rack 43 is welded to the lower portion of the column housing 421.

[0043] The separator plate 41 is designed in a spiral shape, allowing the waste glass to move and be screened along a predetermined trajectory. The upper surface of the separator plate 41 is covered with multiple screening holes 411, each carefully sized to ensure that only qualified fine material can pass through. Furthermore, a fine material collection bin 412 is located within the separator plate 41 to collect the fine material that passes through the screening holes 411. This bin 412 is connected to a fine material discharge port 422, allowing the screened fine material to be smoothly discharged from the fine material discharge port 422.

[0044] A plurality of deceleration plates 413 are arranged on the material distribution plate 41. These deceleration plates 413 cooperate with the spiral direction of the material distribution plate 41 at a specific angle. Through this design, the speed at which the glass slag slides downward can be effectively slowed down, thereby achieving more accurate screening of the glass slag.

[0045] The operating principle of the entire screening assembly 4 is simple and efficient: when glass slag enters the screening assembly 4, it is screened by the screening holes 411 on the distributor plate 41. Fine material that meets the requirements passes through the screening holes 411 into the fine material collection bin 412 and is discharged through the fine material outlet 422. Larger waste materials, guided by the distributor plate 41, continue to move forward for further processing or recycling.

[0046] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the screening device further includes a capping assembly 1 and a screening barrel 3, the capping assembly 1 is connected to the top of the screening barrel 3, and the impurity removal assembly 2 and the screening assembly 4 are sequentially arranged in the screening barrel 3.

[0047] The cover assembly 1, the impurity removal assembly 2 and the screening barrel 3 form a debris separation chamber. The impurities in the glass slag are separated by high-pressure airflow in the impurity removal assembly 2. The cover assembly 1 can effectively prevent the dust generated during the screening process from leaking out 7.

[0048] The screening component 4 and the screening barrel 3 form a screening bin, and the glass slag is screened in the screening component 4 to meet different particle size requirements.

[0049] Furthermore, in some embodiments, the sealing assembly 1 includes a cover plate 11, a through hole 12 and a loading port 13, the loading port 13 is arranged on the upper surface of the cover plate 11, the lower surface of the cover plate 11 is connected to the screening barrel 3, the cover plate 11 is fixedly connected to the fixing mechanism 25, and the through hole 12 is arranged in the middle position of the cover plate 11.

[0050] Specifically, in actual use, the cover plate 11 is firmly connected to the fixing mechanism 25, providing the necessary support for the fixing mechanism 25, thereby ensuring the stable operation of the debris separation mechanism 21. In addition, the provision of the through hole 12 is intended to reduce the high-pressure environment formed inside the debris separation chamber when the air jet 211 continuously sprays high-pressure air during the debris removal process, thereby improving the debris removal effect.

[0051] like Figure 4 ,and Figure 5 As shown, in some embodiments, the screening barrel 3 includes a first shell 32 , a plurality of debris discharge ports 33 and a bottom plate 34 .

[0052] First, the lower end of the first shell 32 is fixedly connected to the bottom plate 34 , and a circumferential support block 31 is provided on the upper portion of the inner wall of the first shell 32 . The support block 31 is slidably connected to the rotating mechanism 22 and provides support for the rotating mechanism 22 .

[0053] Secondly, multiple debris discharge ports 33 are provided on the upper portion of the support block 31. These ports 33 correspond one-to-one with the multiple debris separation mechanisms 21. The collection bag 24 is positioned corresponding to the ports 33 and mounted on the outside of the first housing 32. When the rotating mechanism 22 drives the glass slag to rotate within the screening barrel 3, the debris separation mechanism 21 identifies and separates the debris, which is then discharged through the corresponding debris discharge ports 33. The discharged debris is then collected by the collection bag 24, thereby achieving pure screening of the glass slag.

[0054] It is important to note that the bottom plate 34 is configured as an inclined plate. This design facilitates the flow and aggregation of glass slag during the screening process. The bottom plate 34 also includes a coarse material discharge port 36 and support columns 35. The coarse material discharge port 36 is located at the lowest point of the bottom plate 34, allowing for smooth discharge of coarse material produced during the screening process. The support columns 35 are located on the lower surface of the bottom plate 34, providing stable support for the entire screening barrel 3.

[0055] The typical working process of the above embodiment is as follows: The crushed glass slag smoothly enters the debris separation chamber through the loading port 13 and then naturally falls onto the rotating plate 221. The rotation of the rotating plate 221 evenly distributes the glass slag. At this point, the transmitter 212 precisely transmits a laser beam to the receiver 213. Since both the glass slag and the rotating plate 221 are light-transmitting, an incomplete laser signal captured by the receiver 213 indicates that the glass slag on the rotating plate 221 is mixed with debris.

[0056] After receiving the signal from receiver 213, air jet 211 responds quickly by ejecting high-pressure air toward the glass slag area on rotating plate 221. The powerful action of the high-pressure air effectively separates the glass slag mixed with impurities, which are then discharged smoothly from impurity discharge port 33 and ultimately collected by collection bag 24, achieving precise separation of impurities from the glass slag.

[0057] After the separation of debris is completed, the glass slag is further peeled off from the rotating plate 221 by the baffle 252. As the glass slag gradually accumulates at the baffle 252, part of the glass slag slides to the discharge port 254, then falls to the discharge plate 253, and finally enters the distribution bin, and is safely received by the distribution plate 41.

[0058] Subsequently, the rotating column 42 drives the material distribution plate 41 to rotate regularly. During the rotation process, the fine particles in the glass slag are able to pass through the screening holes 411 into the fine material collection bin 412 and finally slide into the fine material basket 46, achieving efficient screening of the fine particles.

[0059] It is worth noting that the separator plate 41 adopts a spiral design to ensure that the coarser glass slag can roll smoothly along the separator plate 41 to the bottom of the first shell 32. In addition, the bottom plate 34 is designed to be inclined, and a coarse material discharge port 36 is provided at its lowest end to facilitate the smooth discharge of coarse materials in the glass slag from the coarse material discharge port 36, thereby completing the sorting and screening of the glass slag.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
