Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically to an integrated equipment for grading, screening and air separation of photovoltaic panel pyrolysis materials. Background Technology

[0002] Photovoltaic panel pyrolysis material is a mixture of materials produced after waste photovoltaic panels are processed through pyrolysis. These materials typically include glass fragments, metal particles, and organic polymer residues. By separating and processing photovoltaic panels through pyrolysis, resources can be recycled. At the same time, pyrolysis can effectively decompose harmful organic matter in photovoltaic panels, reduce the risk of soil and water pollution caused by the indiscriminate disposal of waste photovoltaic panels, and contribute to the green and sustainable development of the photovoltaic industry.

[0003] The integrated grading, screening, and air classification equipment for photovoltaic panel pyrolysis materials is a processing device used to screen and separate mixtures of photovoltaic panel pyrolysis materials. This equipment combines the functions of grading and screening and air classification to achieve fine separation of photovoltaic panel pyrolysis materials. Grading and screening usually adopts a horizontal vibrating screen, which classifies the pyrolysis materials into different sizes such as large, medium, and small particles through screens with different mesh sizes. The air classification part uses the principle of aerodynamics to achieve further fine separation based on the physical properties of the materials such as weight, density, and volume.

[0004] When using existing integrated grading, screening, and air classification equipment for photovoltaic panel pyrolysis materials, the material is screened using a vibrating screen. Since the screen is usually set at an angle, it is easy for the material to move towards the discharge port for feeding. At the same time, the vibration effect of the screen shortens the time that the material stays on the screen. This makes it easy for small particles to be carried away by large particles and discharged. Moreover, the vibrating screen is difficult to evenly disperse the sticky material in a short time, which leads to a decrease in the effectiveness of the integrated grading, screening, and air classification equipment for photovoltaic panel pyrolysis materials. Utility Model Content

[0005] The purpose of this invention is to provide an integrated equipment for grading, screening, and air separation of photovoltaic panel pyrolysis materials.

[0006] To achieve this objective, the present invention adopts the following technical solution: An integrated grading, screening and air separation equipment for photovoltaic panel pyrolysis material is provided, including a screening box, a screening plate, an air separation mechanism and a pushing mechanism. The screening plate is fixedly installed on the screening box. The screening plate and the air separation mechanism are connected by a material discharge chute. The air separation mechanism is used to perform air separation on the material screened by the screening plate, and the pushing mechanism is used to push the material on the screening plate. The pushing mechanism includes a pushing rod, which is rotatably mounted on the screening plate via a rotating rod that passes through the screening box. The rotating rod drives the pushing rod to swing back and forth on the screening plate, thereby pushing and intercepting the material on the screening plate and increasing the residence time of the material on the screening plate.

[0007] Furthermore, the feeding mechanism also includes a gear, a rack, and a Z-shaped rod. The gear is fixedly installed on the rotating rod, the rack is fixedly installed on the Z-shaped rod via a moving rod, and a guide groove is provided on the top of the screening box. The Z-shaped rod is slidably connected to the guide groove.

[0008] Furthermore, the feeding mechanism also includes a drive rod, a rotating shaft, and a cover plate. The drive rod is fixedly mounted on the rotating shaft and is hinged to the Z-shaped rod via a hinged rod. The rotating shaft is rotatably mounted on the cover plate, and the cover plate is fixedly mounted on the top of the screening box. The rotation of the rotating shaft drives the Z-shaped rod to reciprocate, which in turn causes the gear to drive the rotating rod to reciprocate.

[0009] Furthermore, the feeding mechanism also includes a third motor, which is fixedly mounted on the cover plate, and the output shaft of the third motor is fixedly connected to the rotating shaft.

[0010] Furthermore, the air separation mechanism includes an air separation box, a motor, a feeding cylinder, and a fan. The air separation box is fixedly connected to the material chute, the motor is fixedly installed on the air separation box, the feeding cylinder is rotatably installed on the air separation box, and the feeding cylinder is fixedly connected to the output shaft of the motor. The fan is fixedly installed on the air separation box.

[0011] Furthermore, the air separation mechanism also includes an inclined plate and a scraping mechanism. The inclined plate is fixedly installed inside the air separation box, and the air separation box is provided with a discharge port. The scraping mechanism is used to scrape and push the material on the inclined plate.

[0012] Furthermore, the scraping mechanism includes a scraper plate, a telescopic rod, a connecting rod, and a cylindrical rod. A groove is provided on the inner side of the air classifier box. The scraper plate is slidably mounted on the groove. The telescopic rod is fixedly mounted on the scraper plate and hinged to the connecting rod via a mounting block. The connecting rod is fixedly mounted on the cylindrical rod, which is rotatably mounted on the air classifier box. The rotation of the cylindrical rod allows the scraper plate to move along the groove, thereby enabling it to scrape and clean the residual material adhering to the inclined plate.

[0013] Furthermore, the scraping mechanism also includes a second motor, which is fixedly mounted on the air classifier box, and the output shaft of the second motor is fixedly connected to the cylindrical rod.

[0014] The beneficial effects of this utility model are as follows: This integrated grading, screening, and air-classifying equipment for photovoltaic panel pyrolysis materials, through its pusher mechanism, enables multiple pusher rods to reciprocate and oscillate when the motor rotates, thereby pushing and intercepting the material on the screening plate, increasing the residence time of the material on the screening plate, and thus improving the performance of the integrated grading, screening, and air-classifying equipment for photovoltaic panel pyrolysis materials. In addition, the air-classifying and scraping mechanisms facilitate the discharge of the air-classified material, and simultaneously scrape away and clean the residual material adhering to the inclined plate of the air-classifying mechanism, further improving the performance of the integrated grading, screening, and air-classifying equipment for photovoltaic panel pyrolysis materials.

It includes a screening box 1, screening plates 2, an air separation mechanism 4, and a pushing mechanism 5. Screening plates 2 are fixedly installed on the screening box 1. A vibration motor is installed on the screening box 1 to drive it to vibrate. Multiple screening plates 2 are provided for screening the materials within the screening box 1. The screening plates 2 and the air separation mechanism 4 are connected via a discharge chute 3. The screened materials on the screening plates 2 are transported along the discharge chute 3 to the air separation mechanism 4 for air separation. The air separation mechanism 4 further refines and separates the screened materials by air separation of the materials screened by the screening plates 2. The pushing mechanism 5 pushes the materials on the screening plates 2, thereby intercepting the materials and increasing the time the materials remain on the screening plates 2.

[0021] Reference Figures 3 to 5 The feeding mechanism 5 includes a feeding rod 51, which is rotatably mounted on the screening plate 2 via a rotating rod 52. The rotating rod 52 passes through the screening box 1. Multiple feeding rods 51 and rotating rods 52 are provided. The rotation of the rotating rod 52 causes the feeding rod 51 to reciprocate, thereby intercepting or releasing the material on the screening plate 2. The feeding mechanism 5 also includes a gear 53, a rack 55, and a Z-shaped rod 56. The gear 53 is fixedly mounted on the rotating rod 52, and its rotation causes the rotating rod 52 to rotate. The rack 55 is fixedly mounted on the Z-shaped rod 56 via a moving rod 54, and the moving rod 54 causes the rack 55 to move. A guide groove 57 is provided on the top of the screening box 1, and the Z-shaped rod 56 is slidably connected to the guide groove 57. The guide groove 57 guides the Z-shaped rod 56, preventing it from deviating during movement.

[0022] Reference Figure 5 and Figure 6The feeding mechanism 5 also includes a drive rod 59, a rotating shaft 511, and a cover plate 512. The drive rod 59 is fixedly mounted on the rotating shaft 511 and is hinged to the Z-shaped rod 56 via a hinge rod 58. The movement of the hinge rod 58 drives the Z-shaped rod 56 to reciprocate along the guide groove 57. The rotating shaft 511 is rotatably mounted on the cover plate 512, and the cover plate 512 is fixedly mounted on the top of the screening box 1. The rotation of the rotating shaft 511 drives the drive rod 59 to rotate. The feeding mechanism 5 also includes a motor 510, which is fixedly mounted on the cover plate 512. The output shaft of the motor 510 is fixedly connected to the rotating shaft 511. By starting the motor 510, the rotating shaft 511 can be driven to rotate.

[0023] Reference Figure 1 and Figure 7 The air separation mechanism 4 includes an air separation box 41, a motor 43, a feeding cylinder 44, and a blower 46. The air separation box 41 is fixedly connected to the material discharge chute 3. Through the material discharge chute 3, the material screened by the screening plate 2 enters the air separation box 41. The motor 43 is fixedly installed on the air separation box 41. By starting the motor 43, the feeding cylinder 44 can be driven to rotate. The feeding cylinder 44 is rotatably installed on the air separation box 41, and the feeding cylinder 44 is fixedly connected to the output shaft of the motor 43. Through the rotation of the feeding cylinder 44, in conjunction with the airflow blown by the blower 46, the material can be separated by air separation. The blower 46 is fixedly installed on the air separation box 41. By starting the blower 46, airflow can be blown out of the air separation box 41. The air separation mechanism 4 also includes an inclined plate 42 and a scraping mechanism 47. The inclined plate 42 is fixedly installed on the inner side of the air separation box 41, and the air separation box 41 is provided with a discharge port 45. The air separation box 41 is provided with two inclined plates 42 and two discharge ports 45, which facilitates the discharge of the material separated by air separation from the air separation box 41. The scraping mechanism 47 is used to scrape and push the material on the inclined plate 42, thereby facilitating the cleaning and discharge of the material on the inclined plate 42.

[0024] Reference Figure 7 and Figure 8The scraping mechanism 47 includes a scraper 472, a telescopic rod 473, a connecting rod 474, and a cylindrical rod 476. A groove 471 is provided on the inner side of the air classifier box 41. The groove 471 guides the scraper 472, which is slidably mounted on the groove 471. The movement of the scraper 472 scrapes and cleans the material on the inclined plate 42. The telescopic rod 473 is fixedly mounted on the scraper 472 and hinged to the connecting rod 474 via a mounting block 475. The swinging action of the connecting rod 474 moves the mounting block 475, causing the telescopic rod 473 to drive the scraper 472 to reciprocate along the groove 471. The connecting rod 474 is fixedly mounted on the cylindrical rod 476, which is rotatably mounted on the air classifier box 41. The reciprocating rotation of the cylindrical rod 476 drives the connecting rod 474 to swing back and forth. The scraping mechanism 47 also includes a second motor 477, which is fixedly installed on the air classifier box 41. The output shaft of the second motor 477 is fixedly connected to the cylindrical rod 476. By starting the second motor 477, the cylindrical rod 476 can be driven to reciprocate.

[0025] Reference Figures 1 to 8 This integrated grading, screening, and air-classifying equipment for photovoltaic panel pyrolysis materials utilizes a pushing mechanism. When the motor rotates, it drives multiple pushing rods to reciprocate, thus pushing and intercepting the material on the screening plate. This increases the material's residence time on the screening plate, thereby improving the overall performance of the integrated grading, screening, and air-classifying equipment for photovoltaic panel pyrolysis materials. Furthermore, the air-classifying and scraping mechanisms facilitate the discharge of air-classified material and remove residual material adhering to the inclined plate of the air-classifying mechanism, further enhancing the equipment's effectiveness.
