Description

Technical Field

[0001] This utility model relates to the field of waste recycling and treatment technology, and in particular to a screening device for the resource utilization of waste metal solid waste. Background Technology

[0002] In the current field of scrap metal recycling, it is crucial to achieve efficient resource utilization and sustainable environmental development. With the acceleration of industrialization, the amount of scrap metal generated is increasing day by day, and how to effectively recycle and process this scrap metal has become an urgent problem to be solved.

[0003] A significant challenge in scrap metal recycling is the presence of numerous impurities on the surface of scrap metal. Even after crushing, the scrap metal fragments still contain dust and other solid waste, severely impacting their subsequent utilization value. Traditional screening devices often employ filter screens; however, dust in the scrap metal fragments easily clogs these screens, reducing screening efficiency and increasing equipment maintenance costs. Furthermore, ordinary screening devices struggle to effectively separate other solid waste of similar size from the metal fragments. To address this, an adsorption-type screening device was designed. Utilizing the adsorption effect of a permanent magnet conveyor belt on the metal fragments during transport, it effectively separates the metal fragments from the mixed waste. When the conveyor belt reaches a specific position, a scraper removes the adsorbed metal fragments, improving screening efficiency and avoiding the clogging problems common in traditional screening methods. Utility Model Content

[0004] In view of the technical problems existing in the background art, this utility model provides a waste metal solid waste resource utilization screening device, which can effectively separate metal scraps from mixed waste.

[0020] like Figures 1-3As shown, a waste metal solid waste resource utilization screening device includes a first fixed frame 1, a first conveying trough 2, a second fixed frame 9, and a screening mechanism 6. The first fixed frame 1 has a rectangular frame structure, and the upper part of the first fixed frame 1 is provided with the first conveying trough 2 and the first conveyor belt 3. The second fixed frame 9 is provided at one end of the first fixed frame 1, and the upper part of the second fixed frame 9 is provided with the second conveyor belt 10 and the screening mechanism 6. The screening mechanism 6 includes a third fixed frame 601, a second connecting rod 608, a permanent magnet conveyor belt 606, a scraper 611, and a guide trough 612. The third fixed frame 601 is connected to the second connecting rod 608 through the first connecting rod 604 on the side, and the permanent magnet conveyor belt 606 is provided on the third fixed frame 601. One end of the second connecting rod 608 is fixedly connected to the side of the first fixed frame 1, and the other end of the second connecting rod 608 is provided with a connecting bracket 610, and the scraper 611 is provided inside the connecting bracket 610.

[0021] It should be noted that the upper part of the first fixed frame 1 is provided with a first conveying trough 2, and the first conveyor belt 3 is provided inside it. After solid waste enters from the feed hopper 4, it is transported by the first conveyor belt 3 and adsorbed after reaching the screening mechanism 6. The entire third fixed frame 601 is connected to the side of the first fixed frame 1 through the first connecting rod 604 and the second connecting rod 608. The upper part of the third fixed frame 601 is provided with a permanent magnet conveyor belt 606, which is covered with multiple layers of neodymium iron boron blocks, so that the entire permanent magnet conveyor belt 606 has extremely strong magnetism, which can adsorb metal fragments on the first conveyor belt 3 and transport them to the next working area under the drive of the first conveyor belt 3, realizing automated adsorption and screening.

[0022] It should be further explained that a connecting bracket 610 and a scraper 611 are provided at one end of the second connecting rod 608. The scraper 611 is inclined and attached to the surface of the permanent magnet conveyor belt 606, thereby peeling off the metal debris adsorbed on the permanent magnet conveyor belt 606 and transporting it into the lower third conveyor belt 10.

[0023] like Figures 1-3 As shown, a first drive motor 602 is provided on the upper part of the third fixed frame 601, and a first sprocket on the output shaft of the first drive motor 602 is connected to a third rotating shaft through a first transmission chain 603. A permanent magnet conveyor belt 606 is provided on the third rotating shaft. One end of the connecting bracket 610 is movably connected to a first fixed support 609 on the second connecting rod 608, and a torsion spring is provided at the connection between the connecting bracket 610 and the first fixed support 609. The scraping end of the scraper plate 611 is close to the surface of the permanent magnet conveyor belt 606. A guide groove 612 is provided in the middle of the two second connecting rods 608, and the guide groove 612 is located directly below the scraper plate 611.

[0024] It should be noted that a torsion spring is provided at the connection between the connecting bracket 610 and the first fixed support 609, so that the entire connecting bracket 610 has a certain elastic stress, which makes it easy for the entire scraper 611 to adhere well to the surface of the permanent magnet conveyor belt 606. Moreover, the scraper 611 is made of non-metallic material to avoid being affected by magnetism. The stripped metal debris is guided into the second conveyor belt 10 through the guide groove 612, thereby completing the transfer.

A second drive motor 5 is provided inside the first fixing frame 1, and the second drive motor 5 is connected to the first rotating shaft through the second transmission chain 7. A first conveyor belt 3 is provided on the first rotating shaft. A feed hopper 4 is provided at one end of the first conveying trough 2, and a collection trough 8 is provided at the other end of the first conveying trough 2.

[0026] It should be noted that the entire third fixed frame 601 is movably connected to the cavity of the first connecting rod 604 and the third connecting rod 605. The third connecting rod 605 is set on the second connecting rod 608, which facilitates the adjustment of the height of the entire third fixed frame 601. This design can flexibly adjust the distance between the permanent magnet conveyor belt 606 and the first conveyor belt 3 according to the actual working conditions. When the material conveyed on the first conveyor belt 3 contains metal debris, by optimizing the distance between the two, the magnetic field range of the permanent magnet conveyor belt 606 can be optimally matched with the metal debris, which significantly improves the adsorption efficiency of metal debris on the surface of the first conveyor belt 3 and in the material, and ensures the effective removal of metal impurities.
