Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy waste separation technology, and in particular relates to a high-efficiency separation device for aluminum alloy wheel hub waste. Background Technology

[0002] With the increase in car ownership and the approach of the end of the vehicle's lifespan, waste aluminum alloy wheels have become the core source of recycled aluminum. Their recycling is of great significance to resource conservation and the circular economy. However, the composition of wheel waste is complex. In addition to the aluminum alloy matrix, it also contains impurities such as steel bolts, rubber residues, surface paint layers, and oil stains. It needs to be separated and processed to meet the requirements of smelting.

[0003] Existing separation devices mostly adopt a single-stage separation mode, which removes impurities through a single magnetic separation or sieving. They lack a multi-stage collaborative processing mechanism. This method is difficult to cope with the differences in the form and properties of impurities, resulting in a large amount of magnetic impurities remaining and insufficient separation rate of non-metallic impurities. When residual impurities enter the smelting process, they will increase flux consumption and slag removal costs. They will also cause recycled aluminum to be downgraded due to compositional deviations, reducing the utilization rate of grade preservation. At the same time, they will increase the load on waste gas and waste liquid treatment, which does not meet environmental protection standards. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency separation device for aluminum alloy wheel hub waste. Specifically, during the separation of aluminum recycling waste, the waste falls from the feed hopper to the highest magnetic roller. The hopper receives non-ferrous filings and guides them to the next magnetic roller. Baffles prevent waste from scattering and mixing with other materials. A collection box receives iron filings scraped off by a scraper, and a discharge hopper discharges the iron filings. The three-stage magnetic rollers, in conjunction with the hopper, form a multi-stage separation process, gradually removing iron filings and significantly improving the thoroughness of iron filings separation, reducing iron filings residue, and enhancing separation efficiency. This meets the needs of high-efficiency separation of aluminum recycling waste and iron filings recovery, solving the problem that existing separation devices mostly use a single-stage separation mode, removing impurities through single magnetic separation or screening, lacking a multi-stage collaborative processing mechanism.

[0011] Furthermore, the scraping assembly includes three mounting bases fixedly connected to the top of the three collection boxes respectively.

The separation mechanism 2 is mounted on the frame 1 and is used to separate iron filings from the aluminum recycling waste. The separation mechanism 2 includes three rotating shafts 21 that pass through the frame 1. All three rotating shafts 21 are rotatably connected to the frame 1, and magnetic rollers 211 are fixedly connected to the outer walls of the three rotating shafts 21. The frame 1 is designed as a whole with... The frame 1 has a rectangular inclined surface, and three rotating shafts 21 are evenly distributed on the inclined surface of the frame 1. The separation mechanism 2 also includes a sorting component 22, which is set on the frame 1 and is used to separate and collect iron filings separated from aluminum recycling waste; a drive component 23, which is set on the frame 1 and is used to provide power for the rotation of the three rotating shafts 21; and a scraper component 24, which is set inside the frame 1 and is used to scrape off and collect the iron filings adsorbed on the outer wall of the magnetic roller 211.

[0020] The sorting assembly 22 includes three mounting brackets 221 fixedly connected to the frame 1. Each mounting bracket 221 has a hopper 222 fixedly connected to it, and each hopper 222 has a baffle 223 fixedly connected to it. The three hoppers 222 are welded to their respective mounting brackets 221. The three hoppers 222 are used to transport scrap iron filings from the aluminum recycling waste, allowing the aluminum recycling waste to pass sequentially through three magnetic rollers 211 for separation. Three collection boxes 224 are fixedly connected to the inner wall of the frame 1. Each collection box 224 has a discharge hopper 225 fixedly connected to its front side. The side of each discharge hopper 225 furthest from its corresponding collection box 224 has a... The separator runs through the front side of the frame 1 and is fixedly connected to the frame 1. By setting up the sorting component 22, specifically when sorting aluminum recycling waste, the aluminum recycling waste falls from the feed hopper 11 to the highest magnetic roller 211. The hopper 222 receives non-iron chips and guides them to the next magnetic roller 211. The baffle 223 prevents the waste from scattering and mixing with the material. The collection box 224 receives the iron chips scraped off by the scraper 242. The discharge hopper 225 discharges the iron chips. The three-stage magnetic rollers 211 and the hopper 222 form a multi-stage sorting, gradually removing iron chips, greatly improving the thoroughness of iron chip separation, reducing iron chip residue, and improving the thoroughness of separation; meeting the needs of efficient sorting of aluminum recycling waste and iron chip recycling.

[0021] The drive assembly 23 includes a mounting plate 231 fixedly connected to the rear side of the frame 1. A motor 232 is mounted on the rear side of the mounting plate 231. The output shaft of the motor 232 is fixedly connected to the corresponding rotating shaft 21 via a coupling. Four pulleys 233 are fixedly connected to the outer walls of the three rotating shafts 21. Belts 234 are respectively fitted between two corresponding pairs of pulleys 233. Two tensioning pulleys 235 are fixedly connected to the rear side of the frame 1. The two tensioning pulleys 235 are slidably connected to the corresponding belts 234. The scraper assembly 24 includes three mounting seats 241 fixedly connected to the tops of the three collection boxes 224. Several scrapers 242 are slidably connected to the inner walls of the three mounting seats 241. The tops of the scrapers 242 extend to the outside of the corresponding mounting seats 241. The interiors of the three mounting seats 241 are... Several springs 243 are installed, one end of which is fixedly connected to the inner bottom wall of the corresponding mounting base 241, and the other end is fixedly connected to the corresponding scraper 242. By setting up the scraping assembly 24, when removing iron filings from the magnetic roller 211, multiple scrapers 242 contact the outer wall of the magnetic roller 211 under the action of the corresponding springs 243. The mounting base 241 provides installation support for the scrapers 242 and springs 243. Multiple scrapers 242 achieve segmented coverage of the surface of the magnetic roller 211, which can be independently adapted to different areas of the roller, avoiding large areas of iron filings residue caused by poor local adhesion of a single scraper. It can also disperse the scraping pressure, extend the service life of the scrapers, and avoid large areas of iron filings residue caused by poor local adhesion of a single scraper, thus greatly improving the iron filings scraping effect and operational stability.

[0022] A specific application of this embodiment is as follows: When separating aluminum recycling waste, the aluminum recycling waste is first ground into powder, then conveyed to an elevator by a screw conveyor, and then fed into a transfer tank by the elevator. Subsequently, it is conveyed from the discharge pipe of the transfer tank to the feed hopper 11. The aluminum recycling waste first falls onto the magnetic roller 211, which is closest to the feed hopper 11 and is the highest position, and is guided by the baffle 223. At this time, the motor 232 is started, and the output shaft of the motor 232 drives the corresponding rotating shaft 21 clockwise through the coupling. As the needle rotates, the four pulleys 233 and two belts 234 work together to drive the central shaft 21 and the shaft 21 near the conveyor 12 to rotate clockwise synchronously. This, in turn, drives the three magnetic rollers 211 to rotate together. The two tensioning pulleys 235 slide in contact with their corresponding belts 234 to adjust the tension of the belts 234 and ensure the stability of the transmission. The rotating magnetic rollers 211 use their own magnetism to attract iron filings from the aluminum recovery powder, while the non-iron filings that are not attracted fall into the corresponding hopper 222. Afterwards, the non-ferrous scrap in hopper 222 falls onto the next magnetic roller 211, repeating the above adsorption and separation process. The three magnetic rollers 211 are arranged in sequence to form a multi-stage separation, which can gradually remove iron scrap from the waste, greatly improving the thoroughness of iron scrap separation and reducing iron scrap residue. After adsorption and separation by the three magnetic rollers 211, the iron scrap in the aluminum recycling waste is fully adsorbed. Finally, the non-ferrous scrap enters the conveying device 12 through the last hopper 222 and is transported by the conveying device 12 to the melting workshop for the next step of processing. During operation, as the magnetic roller 211 rotates, the scraper 242 installed in the mounting base 241 on the top of the collection box 224 is always in contact with the outer wall of the magnetic roller 211 under the action of the spring 243, scraping off the iron filings adsorbed on it. The iron filings fall into the collection box 224 and are finally discharged through the discharge hopper 225 for collection. The multiple scrapers 242 can achieve "segmented coverage" of the surface of the magnetic roller 211. Each scraper can be independently adapted to the corresponding area, avoiding large-area iron filings residue caused by poor local adhesion of a single scraper.

[0023] It should be noted that the control of motor 232 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.
