Description
Technical Field
The invention relates to a production device of titanium sponge, in particular to a large cover for preventing deformation in the reduction distillation production of titanium sponge.
Background
At present, the sponge titanium is industrially produced at home and abroad by adopting a Claur method, the main raw materials are magnesium, titanium tetrachloride and argon, the magnesium is used for reducing the titanium tetrachloride, liquid titanium tetrachloride is continuously introduced into a hot end reaction system assembled by a reactor and a large cover, and the titanium tetrachloride and magnesium in a molten state are subjected to oxidation-reduction reaction to mainly generate the sponge titanium and magnesium chloride. The titanium sponge is subjected to high-constant-temperature high-vacuum distillation production after the reduction and feeding of the titanium sponge is finished, magnesium and magnesium chloride in the titanium sponge are mainly contained in a distillation reactor, and the distillation is carried out under the conditions of high vacuum degree and high temperature. In the prior art, the large cover bottom plate is connected with the cylinder body by welding, the welding line on the circumference is long, and all the components are connected by welding lines. During distillation, due to the fact that the difference between the pressure in the large cover and the vacuum pressure in the reactor is large, after the large cover is used for a period of time in production, the large cover bottom plate is deformed into a concave-convex shape, and the welding seam between the large cover bottom plate and the cylinder body is pulled to crack, other welding seams on the bottom plate are also pulled to crack, so that the risk of air inlet is generated during the distillation of the titanium sponge, and the product quality of the titanium sponge is reduced; when the big lid bottom plate is tensile deformation, cause the filling tube sleeve pipe, the evacuation pipe sleeve pipe and the vacuum channel pipe deformation that set up on the big lid, bring certain degree of difficulty when equipment filling tube and vacuum evacuation pipe, increase operative employee's intensity of labour and reduce big lid availability factor's technical problem.
Disclosure of Invention
The invention aims to solve the problems that in the distillation production process of titanium sponge, the pressure difference between the inside of a large cover and the inside of a reactor is large, and the connecting welding seam between a bottom plate of the large cover and a cylinder body is cracked; the feeding sleeve, the vacuumizing pipe sleeve and the vacuum channel pipe are deformed after the large cover bottom plate is stretched and deformed, air inflow is caused to the titanium sponge lump, the product quality is affected, the large cover using efficiency is low, and the labor intensity of operators is increased.
In order to solve the technical problems, the invention adopts the following technical scheme:
a large cover used for preventing deformation in the reduction distillation production of titanium sponge comprises a large flange 1, and a pressurizing pipe 2, an evacuation pipe sleeve 3, a heater shell 4, a vacuum channel pipe 5, a charging pipe sleeve 6, a large cover evacuation pipe 7 and a heat-insulating layer 11 which are respectively arranged on the large flange 1; an annular groove 8 is formed in the bottom of the large flange 1, the top end of a special-shaped seal head 10 is connected in the annular groove 8, and the large flange 1 and the special-shaped seal head 10 form a cavity; the special-shaped end socket 10 is provided with an arc body 9, and the angle of the arc is 45-100 mm.
The beneficial effect of adopting above-mentioned technical scheme is:
1. the invention realizes the replacement of the large cover bottom plate and the cylinder in the prior art by the special-shaped end socket, reduces the tensile crack of the welding line during distillation and avoids the air inlet risk of the product.
2. According to the invention, when the titanium sponge is produced by distillation under high vacuum and high temperature, under the action of the arc body, deformation of the feeding pipe sleeve, the vacuumizing pipe sleeve and the vacuum channel pipe is avoided, and the labor difficulty of an operator in assembling the feeding pipe and the vacuum vacuumizing pipe is reduced; the concave-convex deformation and the weld cracking of the large cover bottom plate are avoided, the air inlet rate of the titanium sponge product is reduced, and the production quality of the titanium sponge is guaranteed.
3. The invention prolongs the service life of the cover and saves the cost of production equipment.
