Slagging-off device for molten aluminum refining

Abstract

The invention discloses a slagging-off device for molten aluminum refining. A slag collecting basket is movably arranged at the lower end of a rotary barrel body in a sleeving mode; through observingthe molten aluminum level, slagging-off equipment can be taken out from a hearth without dross; rotary slagging-off head devices need to be folded at the moment firstly; in the process of the foldingof the rotary slagging-off head devices, each rotary slagging-off head device rotates around a connecting rotating shaft, and an outlet of the inner end of a rotary slagging-off connecting barrel canbe inclined downwards to guide a slag body into the rotary barrel body; the slag body is collected in the slag collecting basket through the rotary barrel body, and the slag collecting basket only needs to be washed after slagging-off every time to be used next time; and thereof, the rotary slagging-off head devices are folded not only for folding, but also for collecting the slag body, and the centralized treatment of the dross removed out is facilitated, so that the automation and the convenience of slagging-off treatment is really realized, and the labor intensity of workers is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of metal smelting and industrial kiln equipment, in particular to a slag removing device for refining molten aluminum. Background technique [0002] In aluminum manufacturing and processing, the melting of aluminum ingots or scrap aluminum blocks into molten aluminum is carried out under high temperature conditions in large box-type melting furnaces, because unmelted aluminum ingots or scrap aluminum blocks are usually of relatively high purity. Low, containing more impurities. After the aluminum ingot or scrap aluminum block is melted into molten aluminum, during the refining process, some impurities will be deposited in the melting furnace, and some scum will float on the surface of the molten aluminum, so the molten aluminum needs to be Slag removal and purification treatment, otherwise floating will seriously affect the quality of castings. [0003] Therefore, these melted scum must be cleaned up in the...
