A kind of slag removal device for aluminum liquid refining

Abstract

The invention discloses a slag removal device for refining aluminum liquid. A slag body collection basket is movably sleeved on the lower end of a rotating cylinder, and the slag removal device can be taken out from the furnace by observing the aluminum liquid level without scum. At this time, it is first necessary to close the rotary slag removal head device. During the retraction process of the rotary slag removal head device, each piece of the rotary slag removal head device rotates around the connecting shaft, and the inner end of the rotary slag removal connection cylinder of each piece of rotary slag removal head device The outlet will tilt downward to introduce the slag into the rotating cylinder, and collect it into the slag collection basket through the rotating cylinder. After each slag removal, you only need to clean the slag collection basket and then use it next time. The folding of the device is not only to realize the folding, but also to collect the scum, so as to facilitate the centralized treatment of the scum, which truly realizes the automation and convenience of scum removal, and greatly reduces the labor intensity of workers.

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...
