Device for automatic exhausting and argon filling of reduction distillation furnace in sponge titanium production

Abstract

The invention discloses a device for automatic exhausting and argon filling of a reduction distillation furnace in sponge titanium production. A three-way pipe sleeve is arranged on a reactor large cover, and a large cover sleeve flange is connected with a vertical pipe flange, a sealing gasket is arranged between the large cover sleeve flange and the vertical pipe flange, a filter screen is arranged at the bottom of a three-way pipe stand pipe, the three-way pipe stand pipe is connected with an argon gas pipeline, and a pneumatic high vacuum baffle valve and a check valve are arranged on theargon gas pipeline. A dust collecting tank is arranged directly below a filter screen arranged in a three-way cross pipe, the three-way cross pipe is connected with a gas recovery tank through a recovery pipeline, and an electromagnetic valve is arranged on the recovery pipeline. By using an automatic argon filling and exhausting device, the automatic production degree of sponge titanium can be improved, argon can be recycled, the labor intensity of operators can be reduced, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a production device of sponge titanium, which is a device for automatic exhausting and argon filling of a reduction distillation furnace in the production of sponge titanium. Background technique [0002] At present, the industrial production of sponge titanium at home and abroad adopts the Krall method, and the main raw materials are magnesium, titanium tetrachloride, and argon. That is, the magnesium reduction method of titanium tetrachloride is to continuously feed titanium tetrachloride into the reactor, and titanium tetrachloride and magnesium in a molten state undergo a reduction reaction to mainly generate sponge titanium and magnesium chloride. During the production process, because the process needs to prevent the air from entering the reactor to pollute the product, it is necessary to maintain a positive pressure in the reactor, but the pressure must not be too high, and production must be controlled within a certain ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of automatic argon filling when the pressure in the reactor is low or when argon needs to be filled according to the requirements of the production process, and automatic pressure discharge when the pressure in the reactor is too high in the production process of sponge titanium reduction distillation. The design provides A device for automatic exhausting and argon filling of reduction distillation furnace in the production of sponge titanium
