Abstract

The invention discloses an ultrahigh-purity aluminum crystallization device. The ultrahigh-purity aluminum crystallization device comprises a rotating body and a driving device, wherein the rotating body is mounted above a crucible, the lower end of the rotating body extends to a position below the liquid level of molten aluminum in the crucible, the driving device is connected with the rotating body and used for driving the rotating body to rotate, a cooling gas line is arranged in the rotating body, and cooling gas is filled into the cooling gas line to cool the rotating body. Further, high-purity aluminum crystals are formed through solidification and accumulation at the lower end of the rotating body. The cooling gas line comprises a gas inlet channel, a gas outlet channel and a conversion channel, wherein the temperature of the rotating body is controlled more finely by converting the circulation direction of the cooling gas line, and the problems that in the prior art, the purification cost is high, and the purification effect is poor are solved.

Description

technical field [0001] The invention relates to a purification device for metal aluminum, in particular to an ultra-high-purity aluminum crystallization device. Background technique [0002] Aluminum products with a purity above 5N5 are called ultra-high-purity aluminum. Ultra-high-purity aluminum is widely used in the fields of electronics, aviation, navigation, chemical and defense industries, and its consumption is increasing year by year. But now there are very few domestic enterprises that can produce 5N5 ultra-high-purity aluminum that meet the needs of users, and there are only a handful of research and development units. Therefore, almost all ultra-high-purity aluminum needed in China depends on imports. [0003] In the prior art, such as the invention patent application document with the application number 201610042682.1, a method for purifying ultra-high-purity aluminum is proposed, including selecting refined aluminum with a purity of at least 4N6; the inner wall ...
