Planetary rotary blowing aluminum melt purifying device

Abstract

The invention discloses a planetary rotary blowing aluminum melt purifying device, which comprises a frame, a degassing box, a top cover, an elevating mechanism, a planetary driving mechanism, a rotary blowing device, a rotary spray head and an air inlet pipe, wherein the elevating mechanism is arranged on the upper part of the frame; the planetary driving mechanism is arranged on an installation seat; the rotary blowing device further comprises a rotating lever; the upper end of the rotating lever is connected with an output shaft of a planetary driver; the rotary spray head is arranged at one end of the rotating lever which is different from the output shaft of the planetary driver, and is positioned in the degassing box; and the air inlet pipe is connected with the rotary spray head. According to the planetary rotary blowing aluminum melt purifying device disclosed by the invention, the rotary spray head has high-speed auto-rotation and low-speed revolution functions simultaneously, bubbles are distributed uniformly in the degassing box, easily reach the corner regions of the degassing box, are dispersed and float uniformly in the degassing box, and are mixed fully with an aluminum melt, the liquid level of the aluminum melt is stable, the diffusion course of hydrogen in the aluminum melt is shortened, gas-liquid contact is strengthened, and the hydrogen removing effect is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a purification device for planetary rotary blown aluminum melt. Background technique [0002] In order to ensure the metallurgical quality of aluminum and its alloys, it is necessary to purify the refined aluminum melt. Reducing the hydrogen content in aluminum melt is one of the main purposes of aluminum melt purification. At present, the dehydrogenation of aluminum melt is mainly based on various dehydrogenation methods developed based on the theory of bubble floating. The hydrogen in the aluminum melt continuously diffuses into the bubbles, and escapes as the bubbles float to the surface of the melt, so as to achieve the purpose of hydrogen removal. [0003] After literature search, it was found that in the article "Hydraulic Simulation of Pulse Air Rotary Injection Technology" published in "Journal of Nonferrous Metals of China" 2002, Vol12, No.1, P44-P47, Jiang Haiyan e...

AI Technical Summary

Problems solved by technology

[0006] The present invention is aimed at the prior art, in the traditional aluminum melt dehydrogenation method, the aluminum melt in the corner area of ​​the degassing box cannot fully contact with a sufficient number of air bubbles, the degassing effect of the aluminum melt is poor, and the aluminum melt liquid The surface fluctuates violently, and the hydrogen absorption of the melt is intensified, which is not conducive to the purification of aluminum melt and other defects. Provide a planetary rotary injection aluminum melt purification device
