Aluminium scrap online furnace returning device and process

Abstract

The invention discloses an aluminium scrap online furnace returning device. The aluminium scrap online furnace returning device comprises an aluminium scrap conveying device, an aluminium scrap primary purifying device, an aluminium scrap remote transmission device, an aluminium scrap final purifying device and a feeding and furnace returning device. The invention also discloses an aluminium scraponline furnace returning process. The aluminium scrap online furnace returning process comprises the following steps: machining and scrap discharging; underground aluminium scrap conveying and collecting; caching; crushing; spin-drying; remotely transmitting; performing secondary magnetic separation; drying; weighing; returning to a furnace and melting; tempering and using. According to the process, an automatic continuous operation mode is adopted; machined aluminium scraps are crushed, spin-dried and subjected to various stages of purifying, and then the aluminium scraps are returned to thefurnace for melting after being cleaned; the slag content of an aluminium scrap liquid is greatly reduced; the quality of an aluminium liquid is ensured; meanwhile, zero aluminium scrap in a system is realized; the operating cost is greatly reduced.

Description

technical field [0001] The invention relates to an on-line recycling device for aluminum shavings, and relates to the field of production of aluminum alloy castings. Background technique [0002] The manufacturing process of aluminum alloy castings includes aluminum alloy solution smelting, casting and machining, and machining will produce a large amount of aluminum scrap. At present, most enterprises use takeaway processing of machined aluminum chips, which causes a lot of waste in cost; some companies use aluminum chips to be melted and returned to the furnace, because aluminum chips contain a large amount of emulsion, water and other impurities, resulting in a large amount of concentrated Smoke, and increase the slag and hydrogen content of molten aluminum in the furnace, resulting in uncontrolled quality of molten aluminum. Therefore, there is an urgent need for a process for returning aluminum shavings to the furnace, which can reduce the cost waste of enterprises in t...
