Titanium purification device and use method

Abstract

The invention discloses a titanium purification device. The titanium purification device comprises a purification bag, a high-pressure and high-temperature inert gas device, a heating device and an exhaust duct, wherein the purification bag is of a closed tank structure, a crucible is arranged in the purification bag, a gap between the crucible and the purification bag is filled with a thermal insulation material, and a cooling device is embedded in the thermal insulation material; an outlet of the high-pressure and high-temperature inert gas device penetrates through the bottom of the purification bag and the thermal insulation material to be communicated with the bottom of the crucible, and a liquid outlet pipe extending out of the purification bag is arranged at the bottom of the crucible; the heating device comprises a middle heater, the upper end of the middle heater is fixed at the top of the purification bag, and the lower end is arranged in a cavity of the crucible; and the exhaust duct is arranged at the top of the purification bag. According to the titanium purification device, preheated inert gas blown from the bottom has a stirring effect on a titanium solution, enabling the surface titanium solution and inner titanium solution to have mass exchange continuously, so that impurities in the titanium solution rise to the liquid level, and volatile impurities are removed.

Description

technical field [0001] The invention relates to the technical field of metal extracting equipment, in particular to a titanium purification device and a method for using the same. Background technique [0002] Because titanium is difficult to extract, the preparation process is very difficult. The smelting process is generally carried out at a high temperature above 800 ° C, and titanium has a strong ability to combine at high temperatures, and can combine with oxygen, carbon, nitrogen and many other elements. Therefore, It must be operated in vacuum or under the protection of an inert atmosphere. In the laboratory, ilmenite is turned into titanium tetrachloride, and then placed in a sealed stainless steel tank, filled with argon gas, so that they react with metal magnesium to obtain "titanium sponge". This kind of porous "titanium sponge" cannot be used directly. It must be melted into liquid in an electric furnace and cast into titanium ingots. But making such an electri...
