Description

Device for preventing vacuum channel from being blocked in titanium sponge production

Technical Field

The utility model relates to a titanium sponge production, in particular to prevent device of vacuum passageway jam in titanium sponge production.

Background

At present, the titanium sponge produced industrially at home and abroad adopts a Kloer method, an inverted U-shaped combination method (shown in figure 1) developed in the furnace type large-scale direction is used for producing the titanium sponge, and the inverted U-shaped combination method is characterized in that the hot end of reduction production is connected with a cold end system for collecting condensate through a transverse passage pipe to form a production system. After the reduction production of the titanium sponge is finished, the hot-end reactor is provided with the titanium sponge, part of magnesium chloride and part of magnesium chloride, the cold-end system is provided with the reactor for collecting the magnesium chloride distilled from the hot end and a small amount of magnesium, and a pure titanium sponge product is obtained after the distillation is finished. However, during distillation, the phenomenon of blocking the vacuum channel is frequently generated, namely, a mixed condensate of magnesium chloride and magnesium is formed at the lower part of a large cover vertical pipe at the cold end. When the vacuum channel is blocked, the vacuum channel can be dredged only by detaching the plug on the large cover, but the mass of the plug is large, the lifting difficulty of an operator is high, an overhead traveling crane is required to be lifted off, and the overhead traveling crane is required to be lifted during installation, so that the running time of the overhead traveling crane is occupied; when the blockage of the vacuum channel is treated, the production must be stopped to prevent the product from being polluted by the inlet air, and the positive pressure is kept in the reducing furnace when a large amount of argon is introduced; after the treatment is finished, the temperature is raised to the process control temperature for distillation, and the time of the whole treatment project needs to be delayed by about 10 hours. Therefore, the treatment of the blocked pipe not only increases the argon consumption and the power consumption, but also delays the production period and increases the labor intensity of operators. Most manufacturers adopt mechanical dredging and electric heating dredging to solve the problem, but the effect is still not ideal. The prior distillation technology has the defects that the distillation channel is blocked: 1. the evacuation tube is too close to the distillation channel. During distillation, when condensate of magnesium chloride and a small amount of magnesium is distilled to enter a cold-end reactor, part of the condensate is condensed at an evacuation pipe due to the close distance between the evacuation pipe and a distillation channel, and the condensate is more accumulated at the evacuation pipe along with the distillation time and finally blocks the vacuum channel; 2. the amount of condensate entering the cold end reactor at the initial stage of distillation is large (the distillation is warmed up to 900-980 ℃ and the high vacuum is started too early), resulting in premature plugging of the distillation channels.
