Technical Field

The invention relates to a production device of titanium sponge, in particular to a feeding big cover for titanium sponge reduction distillation production.

Background

At present, the sponge titanium produced industrially at home and abroad adopts the Claur method, and the main raw materials are magnesium, titanium tetrachloride and argon. The method for reducing titanium tetrachloride by magnesium is to continuously introduce liquid titanium tetrachloride into a reactor, and the titanium tetrachloride and magnesium in a molten state are subjected to a displacement reaction to mainly generate titanium sponge and magnesium chloride. In the production process, proper argon gas needs to be filled for protection to prevent air from entering the reactor to pollute products, and the pressure in the reactor needs to be controlled within a certain range for production; in order to prevent the titanium tetrachloride from low-temperature reaction and affecting the product quality while sintering the product, the temperature in the reactor needs to be controlled within a certain range. In the prior art, the straight tube is fed in the reduction process, no matter how the material speed changes, the reaction point is always carried out at a fixed point position on the reaction liquid surface, the local magnesium amount of the reaction point is insufficient, the normal reaction is not facilitated, and the product quality is influenced.

Disclosure of Invention

The invention aims to solve the technical problems that in the reduction production process of titanium sponge, feeding reaction points are always carried out at fixed point positions on the reaction liquid surface, so that the local magnesium amount of the reaction points is insufficient, the reduction reaction is not facilitated, and the product quality is influenced.

In order to solve the technical problems, the invention adopts the following technical scheme:

a big charging cover for titanium sponge reduction distillation production comprises a big flange 1, and an evacuation pipe 2, a heater cylinder 3, a vacuum channel pipe 4, a big cover cylinder 5, a heat preservation layer 6, a big cover cylinder bottom plate 7 and a charging sleeve 8 which are respectively arranged on the big flange 1; the large cover cylinder 5 below the large flange 1 is connected with a large cover cylinder bottom plate 7 to form a closed cavity, and the heat insulation layer 6 is arranged in the closed cavity; the feeding sleeve 8 passes through the large cover flange 1 and the large cover cylinder bottom plate 7;

the feeding sleeve 8 and the large cover flange 1 form an included angle of 30-75 degrees, three to five feeding sleeves 8 are uniformly distributed on the same circumference, the motion trail of the action reaction point changes along with the change of the material speed, the full reaction is facilitated, the titanium lump structure is improved, and the subsequent distillation is facilitated.

The beneficial effect of adopting above-mentioned technical scheme is:

1. according to the invention, when the titanium sponge is reduced, a low-temperature reaction area is reduced (or stopped), the multi-pipe inclined feeding is adopted, the inclined feeding is carried out on the same circumference, the motion trail of a reaction point changes along with the change of the feeding speed, the full reaction is facilitated, the titanium lump structure is improved, and the subsequent distillation is facilitated.

the feeding sleeve 8 and the large cover flange 1 form an included angle of 30-75 degrees, three to five feeding sleeves 8 are uniformly distributed on the same circumference, the motion trail of the action reaction point changes along with the change of the material speed, the full reaction is facilitated, the titanium lump structure is improved, and the subsequent distillation is facilitated.

Before the reduction feeding production of the titanium sponge, connecting pipelines, when the pressure and the temperature in the reactor meet the requirements, feeding materials obliquely on the same circumference through a feeding inclined tube, wherein the motion trail of a reaction point changes along with the change of the material speed, continuously feeding titanium tetrachloride materials into the reactor, enabling the titanium tetrachloride materials to react with magnesium to produce titanium and magnesium chloride, and intermittently removing the magnesium chloride. By utilizing the device, the problems that the titanium tetrachloride has insufficient relative magnesium content at a reaction point in the reduction process, cannot react normally, influences the structure of the titanium lump and is unfavorable for subsequent distillation are avoided; further improve titanium and stick together the structure, promote product quality.
