Abstract

The invention provides a suspended degassing device which is high in structural stability, has small vibration amplitude during the running process, effectively avoids sloshing of molten aluminum and guarantees the refining quality. The suspended degassing device comprises a frame, a graphite rotor, a gas blowpipe and a rotor driving device, wherein the graphite rotor is connected with the gas blowpipe through a connecting sleeve. The suspended degassing device is characterized by further comprising a guide rail, a lifting platform, a guide pillar and a lifting driving device, wherein a plurality of cross beams are arranged on the frame; the guide rail and the guide pillar are parallel to each other and are supported by the cross beams; two ends of the lifting platform are connected with the guide rail and the guide pillar in a sliding way respectively; a bearing block is fixed at the lower part of the lifting platform; the gas blowpipe and the bearing block are mounted in a matching way; and a driven wheel and an elastic support piece are arranged on the lifting platform.

Description

technical field [0001] The invention relates to a degassing device for aluminum alloy smelting, in particular to a hanging type degassing device. Background technique [0002] In the aluminum alloy smelting process, a degasser is usually used to blow and refine the molten aluminum. The main principle is: through the rotor rotating at high speed and injecting inert gas, the large bubbles of the inert gas are broken into very fine small bubbles, and the It is evenly dispersed in the molten metal. By reducing the diameter of the bubbles, the total surface of the bubbles increases dramatically, so that more inert bubble surfaces are in contact with hydrogen and impurities in the molten metal, thereby bringing these harmful substances to the surface of the liquid . The structural stability of the existing degasser is poor, and the equipment vibrates violently during operation, which causes the molten aluminum to slosh and affects the refining effect.
