Description

Technical Field

[0001] The utility model relates to the technical field of slag recovery, in particular to a slag recovery device for waste aluminum smelting. Background Art

[0002] At present, the recycling of aluminum products mainly involves crushing aluminum-containing waste materials, placing them into an aluminum melting furnace for smelting, and melting them into aluminum liquid under the action of a catalyst at a high temperature of about 700°C. The smelted aluminum liquid is then poured into a mold for molding, and then cooled to form a high-purity aluminum ingot. However, since all impurities cannot be completely removed from waste aluminum products before smelting, a large amount of scum will be generated on the surface of the aluminum liquid during the smelting process, which needs to be removed in time before the high-purity aluminum liquid can be cooled and molded. At the same time, the scum also contains a certain amount of aluminum that can be recycled and processed to improve the recycling rate of aluminum. However, the main problem in the prior art is that the scum is not completely recovered. The scum is only filtered by a filter, and the simple filtering device has poor effect and is not practical.

The servo motor is started, and the servo motor drives the lead screw to rotate. Under the limiting and guiding action of the slider and the slide groove on the movable plate, the lead screw rotates and drives the movable plate to slide along the length direction of the lead screw, and then drives the mounting column and the connecting plate to move through the slider, and the connecting plate moves with the recovery frame. The recovery frame slides on the horizontal plane of the aluminum liquid, and the scum on the surface of the aluminum liquid is salvaged through the filter holes on the surface, and then the aluminum liquid is discharged through the discharge pipe, so that a part of the scum remaining in the aluminum liquid is filtered twice through the filter screen in the discharge pipe to improve the recovery effect.
