Aluminum Ash Separator

Abstract

The invention relates to an aluminum ash separator. The aluminum ash separator comprises an ash frying pot, a rack and a stirrer, wherein the stirrer is fixed at the upper part of the ash frying pot by virtue of the rack and comprises a stirring shaft and a plurality of stirring rods, the lengths of the stirring rods are different, the length of the stirring rod located below is smaller than that of the stirring rod located above, the ash frying pot is cylindrical and comprises a pot body and a pot bottom, the pot bottom is provided with a liquid discharge opening, the pot body is provided with an ash discharge opening, ash discharge steps are arranged in the ash frying pot, are arranged along the circumferential direction of the ash frying pot, are level with the ash discharge opening in height and are connected end to end, so as to form a molten aluminum tank, the diameter of the molten aluminum tank gradually decreases from top to bottom, and the lengths of the stirring rods are matched with the diameter of the molten aluminum tank. According to the aluminum ash separator, ash residues are not required to be removed during ash frying, so that time and labor are saved.

Description

technical field [0001] The invention relates to a device for producing aluminum, in particular to a separator for removing aluminum ash in molten aluminum. Background technique [0002] In the production process of aluminum ingots, since the raw material aluminum is recycled waste aluminum, in the production process, these waste aluminum materials need to be melted and purified, because these waste aluminum materials contain a large amount of impurities, before forming aluminum ingots These impurities must be removed, and the concentration of the molten aluminum should be increased as much as possible. The purer the molten aluminum, the higher the price of the produced aluminum ingots and the higher the profit. Therefore, during the melting process, these aluminum ash containing impurities will be discharged. However, these discharged aluminum ash also contain about 20% aluminum liquid, which will cause serious waste of aluminum if not recycled. Therefore, in enterprises t...

AI Technical Summary

Problems solved by technology

[0005] 1. The frying ash pot is a cylindrical pot. When frying ash, the aluminum liquid forms a cylindrical shape in the pot, and the surface tension of the entire aluminum liquid is the same. In this way, when workers put ash from the ash outlet, the ash It is not easy to flow away from the ash outlet. For a long time, there will be accumulation of ash at the ash outlet. Workers have to regularly remove these ash, which is time-consuming and laborious

[0006] 2. There is only one stirring rod on the stirring shaft of the stirrer. When stirring, only the aluminum liquid at the bottom can be stirred, so that a vortex will appear, and the aluminum ash on the surface of the aluminum liquid may be stirred to the bottom of the ash frying pot. Released from the liquid discharge port, polluting the purified aluminum liquid

[0007] 3. The whole wok is made of iron wok, which has poor thermal insulation performance, large heat loss, large power consumption, and high purification cost
