Sealing device for automatic discharging and pneumatic stirring of magnesium slag in magnesium refining production

Abstract

The invention discloses a sealing device for automatic discharging and pneumatic stirring of magnesium slag in magnesium refining production. The device comprises a magnesium refining crucible, a flange, a high-temperature-resistant sealing ring, a large cover, an argon gas discharge port, a magnesium material port and a screw conveyer, wherein a barrel body is arranged in the center of the magnesium refining crucible, the bottom end of the barrel body is arranged at the bottom in the magnesium refining crucible, and the bottom end of the barrel body is arranged in a horn mouth shape; a magnesium slag discharge pipe is arranged at the position, between the large cover and a high-temperature pump, on the barrel body, an argon gas filling pipeline is arranged on one side of the barrel body,the upper part of the argon gas filling pipeline is arranged above the large cover, and an argon gas filling opening is formed in the top end of the argon gas filling pipeline; and the lower part of the argon gas filling pipeline is arranged at the lower part in the magnesium refining crucible; an argon gas annular box body which is connected with the bottom end of the argon gas filling pipeline into a whole is arranged above a horn mouth, and rotary nozzles are arranged at the top of the argon gas annular box body; and the auger is arranged in the barrel body, and the top end of the auger isconnected with the high-temperature pump. According to the device, sealed refining is performed, magnesium slag automatic discharging, fully pneumatic stirring, good stirring depth and large strengthare realized, the production power consumption is reduced, the production efficiency is greatly improved, and then the yield and the quality of a refined magnesium product are improved; and meanwhilethe production cost and the labor intensity of operators are reduced.

Description

technical field [0001] The invention relates to a magnesium production device, in particular to a closed device for automatic discharge of magnesium slag and pneumatic stirring in magnesium refining production. Background technique [0002] At present, magnesium refining at home and abroad mostly uses the solvent method to remove impurities in the crude magnesium. Magnesium chloride is electrolyzed to obtain crude magnesium, and the impurities in the crude magnesium are also removed through the solvent method to achieve the quality of refined magnesium, especially in sponge titanium manufacturers. The purity requirements for refined magnesium are particularly high, which directly affects the quality of sponge titanium products. Since the purchased magnesium ingots and electrolyzed crude magnesium have more impurities, the magnesium ingots or electrolytic magnesium enter the magnesium refining crucible to be melted and refined, and the metal impurities and non-metal impuritie...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the technical problems that the magnesium slag cannot be automatically discharged and the manual stirring is insufficient, the stirring depth is poor and the strength is small, and the power consumption is increased during the magnesium refining production process.
