A slag extractor

Abstract

The application provides a slag removing machine and relates to the technical field of molten aluminum mixing production. The slag removing machine comprises a supporting rod, a rotating rod rotatably connected to the lower end of the supporting rod, a stirring rod connected to the lower part of the rotating rod, a connecting sleeve connected to the upper part of the rotating rod and capable of rotating relative to the rotating rod, a lifting support for longitudinally moving the supporting rod and the connecting sleeve, a lifting plate fixedly connected to the connecting sleeve through a first connecting rod, a filter plate rotatably connected to the lifting plate through a connecting shaft, and a plurality of filter plates arranged in parallel and at intervals. The connecting sleeve and the connecting shaft are connected through a transmission mechanism to switch the filter plate between a horizontal state and a vertical state. When each filter plate is in the horizontal state, any two adjacent filter plates are close to each other. When the residual slag in the mixing furnace is removed, the filter plate also rotates, but the filter plate is not driven by the stirring rod, the rotation of the filter plate is relatively slow, and the residual slag and the surface layer of the molten aluminum in the mixing furnace are not easy to be splashed by the filter plate.
