Abstract
The invention relates to an aluminum alloy scrap recycling device. The aluminum alloy scrap recycling device comprises a support and a crushing device; a conveying belt is arranged on one side of thecrushing device; a magnetic separation cylinder is arranged on one side of the conveying belt; a rotating shaft is arranged in the magnetic separation cylinder; a spiral blade is arranged on the rotating shaft; a plurality of magnets are arranged on the spiral blade; a driving motor is arranged on the rotating shaft; a first feeding opening is formed in the magnetic separation cylinder; a feedinghopper is arranged at the first feeding opening; a first discharging opening is formed in the magnetic separation cylinder; a fan is arranged at the first discharging opening; a receiving box is arranged below the first discharging opening; a first liquid outlet is formed in the bottom wall of the receiving box; a first liquid outlet pipe is arranged at the first liquid outlet; a first valve is arranged on the first liquid outlet pipe; a cleaning device and a drying device are arranged on one side of the receiving box; and a smelting device is arranged on one side of the driving device. An aluminum alloy scrap recycling technology sequentially includes crushing, magnetic separation, winnowing, acidification, cleaning, drying, smelting, raking and casting. By the aid of the device and the technology, scraps in secondary aluminum raw materials can be separated, and the finished product quality after reuse of the secondary aluminum raw materials can be improved.
Description
technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to an aluminum alloy scrap recycling device and processing technology. Background technique [0002] Aluminum alloy is a metal compound with low density, relatively high strength, good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry. Some aluminum alloys can be obtained by heat treatment. Good mechanical properties, physical properties and corrosion resistance. At present, aluminum alloy, as one of the most widely used non-ferrous metals in industry, is mainly used in the fields of aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. However, in the processing and manufacturing of aluminum alloy, the waste is becoming more and more serious, making it Lower utilization. [0003] The application document with t...
