Description

Technical Field

[0001] The utility model relates to a reduction production device for titanium sponge, in particular to a separation device for separating low-priced titanium and mixed gas in the production of titanium sponge. Background Art

[0002] Most of the industrialized production of titanium sponge at home and abroad adopts the Klauer process. The main raw materials are refined magnesium, refined titanium tetrachloride and argon. Magnesium reduces titanium tetrachloride by continuously introducing liquid refined titanium tetrachloride into the reactor. Refined titanium tetrachloride reacts with refined magnesium in a molten state to mainly produce titanium sponge and magnesium chloride. In order to maintain continuous production, magnesium chloride needs to be discharged regularly. During the production process, appropriate argon gas protection is required to prevent the air from entering the reactor and polluting the product. The pressure in the reactor must be kept under positive pressure and the pressure is controlled within a certain range. Refined titanium tetrachloride vaporizes at high temperature and reacts with magnesium in a molten state in an exothermic reaction. During the production process, the pressure in the reactor is too high and needs to be relieved in time; pressure relief is also required before each discharge of magnesium chloride, and the number of pressure reliefs is relatively large. Pressure relief is mainly to discharge mixed gases (titanium tetrachloride gas, argon gas) and incompletely reacted titanium low-priced substances. Utility Model Content

Low-priced titanium with large gravity sinks into the cone cylinder 3 by its own gravity. When a certain amount is reached, the blind plate 8 is opened, and then it is discharged from the slag discharge pipe 5. If the slag discharge pipe 5 is blocked, it is cleared by using a brazing rod through the dredging pipe 10.
