Description

Technical Field

[0001] This invention relates to the field of aluminum alloy processing technology, and in particular to a high-efficiency recycling and sorting device for high-weather-resistant aluminum alloy waste. Background Technology

[0002] Due to their lightweight, high strength, corrosion resistance, and recyclability, aluminum alloys have become a core structural material in fields such as building curtain walls, rail transportation, new energy equipment, and marine engineering. To adapt to harsh service environments such as long-term outdoor exposure to sunlight and rain, coastal salt spray, industrial acid and alkaline atmospheres, and extreme temperature changes, high weather-resistant aluminum alloys have significantly improved salt spray resistance, aging resistance, and structural stability through optimized alloy compositions of magnesium, silicon, manganese, and rare earth elements, along with surface treatment processes such as anodizing and fluorocarbon spraying. This has led to large-scale applications and a continuously growing demand for end-of-life recycling.

[0003] Currently, the sorting and separation of scrap aluminum is still mainly based on manual sorting, magnetic separation, air separation, simple crushing and screening, and conventional eddy current separation. These methods generally suffer from problems such as low efficiency, poor precision, and weak adaptability, making it difficult to meet the requirements for efficient and accurate sorting of high weather-resistant aluminum alloy scrap.

[0004] High-weather-resistant aluminum alloys are often mixed with ordinary architectural aluminum, die-cast aluminum, iron parts, plastics, rubber, coating residues, etc., and the dense weather-resistant coating on the surface is firmly bonded to the substrate, making it difficult to remove efficiently using traditional pretreatment methods. This results in insufficient sorting purity and large fluctuations in the composition of recycled aluminum. Secondly, manual sorting relies on experience and judgment, which is labor-intensive, has low throughput, and a high rate of missorting, making it impossible to accurately distinguish alloy series. Conventional mechanical sorting can only achieve particle size and density classification, and has no ability to identify and sort high-weather-resistant aluminum alloys with similar compositions and small density differences. Thirdly, magnetic separation can only remove ferromagnetic impurities, and has limited effectiveness in removing non-ferrous metal inclusions such as copper, zinc, and magnesium, as well as non-metallic coating impurities. Eddy current separation is prone to entrainment and missed sorting of thin, flaky, and fine materials, resulting in low recovery rates. Fourth, most existing equipment is of general design and has not been specifically optimized for the compositional characteristics, surface coating properties and hybrid morphology of high weather-resistant aluminum alloys. It has defects such as easy material blockage, rapid wear, poor sorting stability and low degree of continuity, resulting in a large amount of high weather-resistant waste that can only be downgraded and reused.

[0005] As the recycled aluminum industry upgrades towards high quality, grade preservation, and intelligent manufacturing, and as high-end manufacturing places increasing demands on the uniformity of recycled aluminum alloy composition and strict control of impurities, existing sorting technologies and equipment have become a key bottleneck restricting the high-value recycling of high-weather-resistant aluminum alloy waste.

[0006] Based on this, the present invention provides a high-efficiency recycling and sorting device for high weather-resistant aluminum alloy waste. Summary of the Invention

Detailed Implementation

[0025] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 8As shown, a high-efficiency recycling and sorting device for high weather-resistant aluminum alloy waste includes a sorting mechanism 1. The sorting mechanism 1 includes a sorting cylinder 101. A sorting rotating rod 107 is horizontally rotatably installed inside the sorting cylinder 101. The sorting rotating rod 107 is provided with a spiral transmission groove for conveying aluminum alloy waste. A cylindrical sliding groove is provided inside the sorting rotating rod 107. A sorting support plate 102 is fixedly installed at the bottom of the sorting cylinder 101 by an electric push rod. An adjusting sorting rod 108 is fixedly installed on the sorting support plate 102. The adjusting sorting rod 108 is provided with multiple magnets of different magnetic properties. 8. The sorting rod 108 slides laterally in the cylindrical groove on the sorting rod 107. The sorting support plate 102 is fixedly installed with a transmission wire 103 connected to the control system. The magnetism of the electromagnet on the sorting rod 108 from one end of the transmission wire 103 to the other end is adjusted from strong to weak to attract aluminum alloys of different materials. The aluminum alloy waste with magnetism adheres to the outer wall of the sorting rod 107 and rotates with the sorting rod 107. The aluminum alloy waste without magnetism is driven by the spiral transmission groove on the sorting rod 107 to move laterally in the sorting cylinder 101 at the bottom of the sorting rod 107.

[0027] like Figures 1 to 8 As shown, when aluminum alloy scrap is significantly affected by magnetism and difficult to detach from the sorting rotating rod 107, the electric actuator between the sorting cylinder 101 and the sorting support plate 102 is activated to drive the adjusting sorting rod 108 to slide laterally within the sorting rotating rod 107. The position of the electromagnet on the adjusting sorting rod 108 is adjusted, causing the stronger magnet to move to the outside, weakening the magnetism of the magnet inside the sorting rotating rod 107, allowing the aluminum alloy scrap to detach from the sorting rotating rod 107, thereby sorting aluminum alloy scrap of different materials.

[0028] like Figures 1 to 8As shown, a gear is fixedly installed on the sorting rotating rod 107, and a sorting drive motor 109 is fixedly installed on the sorting cylinder 101. The gear on the sorting drive motor 109 meshes with the gear on the sorting rotating rod 107. The sorting drive motor 109 drives the sorting rotating rod 107 to rotate within the sorting cylinder 101. An arc-shaped screening plate 111 is fixedly installed inside the sorting cylinder 101. The arc-shaped screening plate 111 is fixedly installed at the bottom of the sorting rotating rod 107. The arc-shaped screening plate 111 has filter holes that gradually widen to filter aluminum alloy waste of different sizes, sorting and discharging it. A sorting belt bracket 104 is fixedly installed on the outside of the sorting cylinder 101. A sorting positioning belt 105 is rolled on the sorting belt bracket 104, and multiple sorting scrapers 106 are fixedly installed on the sorting positioning belt 105. The scraper 106 slides in conjunction with the spiral groove on the sorting rotating rod 107. The scraper 106 is used to scrape off aluminum alloy waste that adheres to the spiral groove. When the sorting drive motor 109 drives the sorting rotating rod 107 to rotate, the scraper 106 and the spiral groove of the sorting rotating rod 107 engage, causing the sorting positioning belt 105 to roll on the sorting belt bracket 104. At the same time, the scraper 106 slides forward in the spiral groove of the sorting rotating rod 107, scraping off the aluminum alloy waste adsorbed in the spiral groove. This prevents the scraper from being carried along by the sorting rotating rod 107 and instead scrapes it off by the scraper 106, causing it to move forward synchronously with the scraper 106. During the movement, the electromagnet on the sorting rod 108 is adjusted to gradually weaken the magnetism, causing the aluminum alloy waste with weaker magnetism to fall off one by one. This allows for accurate sorting of aluminum alloy waste with different magnetic properties.

[0029] like Figures 1 to 8 As shown, a discharge trough 112 is fixedly installed at the bottom of the sorting cylinder 101. A drainage filter screen is provided on the discharge trough 112. Multiple mutually spaced discharge slides are provided on both sides of the discharge trough 112. The discharge slides on both sides of the discharge trough 112 are located at the bottom and side of the sorting rotating rod 107, respectively. The discharge slide at the bottom of the sorting rotating rod 107 is used to sort and transport non-magnetic aluminum alloy waste and impurities. The discharge slide on the side of the sorting rotating rod 107 is used to sort and transport aluminum alloy waste with different magnetic intensities.

[0030] like Figures 1 to 8 As shown, a feed inlet is fixedly installed at the front end of the top of the sorting cylinder 101, and a rinsing water tank 110 is fixedly installed at the rear end of the top of the sorting cylinder 101. A water spray nozzle is provided at the bottom of the rinsing water tank 110. The rinsing water tank 110 is connected to an external water pump through a pipe. The external water pump transmits water flow into the rinsing water tank 110, and the water flow is sprayed into the sorting cylinder 101 through the water spray nozzle at the bottom of the sorting cylinder 101 to clean the oil and impurities on the aluminum alloy waste.

[0031] like Figures 1 to 8As shown, a transport processing mechanism 2 is fixedly installed at the bottom of the sorting cylinder 101. The transport processing mechanism 2 includes a transport support 201, which is fixedly installed on both sides of the bottom of the sorting cylinder 101. A pair of transport transmission rods 202 are horizontally rotatably mounted on the transport support 201, and a filter conveyor belt 205 is rolled between the transport transmission rods 202. An isolation support 207 is fixedly installed on the top of the transport support 201. The isolation support 207 is provided with sorting partitions for separating the already sorted aluminum alloy waste. Multiple baking devices 206 are fixedly installed on the isolation support 207. An impurity removal groove 203 is fixedly installed inside the transport support 201. A transmission drive motor 204 is fixedly installed on the transport support 201. The transmission drive motor 204 is fixedly connected to the transport transmission rod 202. By starting the transmission drive motor 204, the transport transmission rod 202 is driven to rotate. The rotation of the transport transmission rod 202 drives the filter conveyor belt 205 to roll inside the transport support 201. The filter conveyor belt 205 is used to transport the sorted metal waste and separate the waste through the isolation support 207. During this process, the metal waste is heated and baked by the baking device 206 to remove the oil and plastic attached to the metal waste. The waste is then discharged through the impurity discharge tank 203, thus completing the accurate sorting and preliminary treatment of the metal waste.
