Efficient high-purity aluminum purification device

Abstract

The invention discloses an efficient high-purity aluminum purification device, which comprises a furnace shell supported on a support, an electromagnetic resistance furnace jacket in the furnace shell, and a cylindrical pot body surrounded by the electromagnetic resistance furnace jacket, wherein the electromagnetic resistance furnace jacket is of a vertical 12-blade cylindrical structure, and anoutwards folded blade end of the upper part of the electromagnetic resistance furnace jacket is a power connection end; the cylindrical pot body comprises an upper purification compound pot and a lower purification ingot compound pot which are overlapped together, and a feed port and a discharge port of the purification compound pot are sealed by flange covers; and a supporting ring is arranged at the outer side of the upper part of the purification compound pot, and the lower end of the ingot compound pot is supported on a lifting mechanism. The two pot bodies are vertically, alternately andrepeatedly heated to be used for purification, so that the working efficiency is greatly enhanced. In the lifting or falling process of the pot body, the other pot body is always pre-heated, accordingly, the waste of electric energy is avoided, the empty consumption electric energy is greatly reduced, the quality and the yield of high-purity aluminum products are also substantially improved, and the running cost is reduced.

Description

1. Technical field [0001] The invention belongs to the technical field of aluminum metallurgy, and in particular relates to a high-efficiency high-purity aluminum extraction device. 2. Background technology [0002] At present, in the non-ferrous metal industry at home and abroad, in the smelting and purification of ultra-high-purity metal aluminum, two technologies, directional solidification and zone smelting, are mainly used, that is, the electromagnetic induction zone and the metal aluminum melting pot, which move relatively slowly first. It is a purification technology that heats and melts metal aluminum, and then slowly cools it. There are two types of furnaces: horizontal and vertical. For example, the patent name "High Purity Aluminum Extraction Device" (Patent No.: 200610134389.4) discloses a vertical furnace type extraction device. The device includes a vertical blade cylindrical electromagnetic induction furnace cover, a vertical truncated pot in the furnace cove...

AI Technical Summary

Problems solved by technology

However, the device has the following deficiencies during use: 1. Due to the operation of a single pot body, it is necessary to wait for the pot body to complete a working cycle each time before the next round of operation can be performed, and the work efficiency is low; In the process of lifting the body upward for more than 10 hours, the electromagnetic induction furnace cover must always be powered

In this way, in the process of slowly lifting and purifying the pot body, about 40% of the electric energy will be wasted in vain;
