Description

Technical Field

[0001] The utility model relates to an aluminum liquid dehydrogenation device, belonging to the technical field of aluminum liquid dehydrogenation. Background Technique

[0002] When aluminum alloy is melted and poured, a large amount of hydrogen will be inhaled. During cooling, hydrogen will continuously precipitate due to the decrease in solubility. The solubility of hydrogen dissolved in aluminum alloy increases with the increase of the temperature of the alloy liquid and decreases with the decrease of the temperature. When changing from liquid state to solid state, the solubility of hydrogen in aluminum alloy decreases. Therefore, during the cooling and solidification process of aluminum alloy liquid, when the content of hydrogen exceeds its solubility, it will precipitate in the form of bubbles. If the hydrogen bubbles formed due to the precipitation of supersaturated hydrogen cannot float up and escape in time, they will form fine and dispersed pores during the solidification process, that is, the so-called pinholes. To improve the quality of aluminum liquid, a dehydrogenation device is used to fill nitrogen into the aluminum liquid and stir the aluminum liquid to cause the hydrogen contained in the aluminum liquid to be discharged, which plays a role in improving the quality of aluminum liquid.

[0003] Although the existing dehydrogenation devices can perform daily dehydrogenation treatment on aluminum liquid, in actual use, the stirring rod can only perform stirring operations at the same position. The stirring rod with a fixed position results in a small range of nitrogen discharge. The aluminum liquid far from the stirring rod can only have nitrogen by relying on the vortex, which makes the dehydrogenation time too long, and thus the working efficiency of the dehydrogenation device is low. In addition, the exhaust holes of the stirring rod are easily blocked by impurities in the aluminum liquid, and the staff needs to clean them regularly, which brings inconvenience to the use of the staff, and thus the dehydrogenation device has insufficient usability.
