Net-shaped supporting type large cover for titanium sponge reduction distillation production

Abstract

The invention relates to a net-shaped supporting type large cover for titanium sponge reduction distillation production. The net-shaped supporting type large cover comprises a large flange and furthercomprises a pressurizing pipe, a cylinder body, a large cover bottom plate, an evacuation pipe sleeve, a heater shell, a vacuum channel pipe, a feeding pipe sleeve and a large cover evacuation pipe which are arranged on the large flange. The large flange is connected with the large cover bottom plate through the cylinder body to form a closed cavity, and a heat preservation layer is arranged in the closed cavity. A net-shaped supporting structure is arranged between the large flange and the large cover bottom plate and is formed in a casting manner. The net-shaped supporting structure is composed of arc plates A, B and C and rib plates A and B; the rib plates B are arranged at the two sides of the feeding pipe sleeve to form triangular arrangement; under the action of the net-shaped supporting structure, concave-convex deformation and weld joint tension fracture of the large cover bottom plate are avoided, the air inlet rate of a titanium sponge product is reduced, and the productionquality of titanium sponge is guaranteed; and deformation of the feeding pipe sleeve, the evacuation pipe sleeve and the vacuum channel pipe is avoided, and the labor difficulty of assembling a feeding pipe and a vacuum evacuation pipe by an operator is reduced.

Description

technical field [0001] The invention relates to a production device of sponge titanium, in particular to a large net-shaped support cover used in the reduction distillation production of sponge titanium. Background technique [0002] At present, the industrial production of sponge titanium at home and abroad adopts the Claure method. The main raw materials are magnesium, titanium tetrachloride, and argon. Liquid titanium tetrachloride is introduced, and titanium tetrachloride reacts with magnesium in molten state to produce titanium sponge and magnesium chloride. After the reduction and feeding of sponge titanium, it enters the high constant temperature and high vacuum distillation production. The main distillation is the magnesium and magnesium chloride in the sponge titanium contained in the reactor. The distillation is carried out under high vacuum and high temperature. The difference in vacuum pressure is relatively large. After a period of use, the bottom plate of the ...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that during the production process of sponge titanium distillation, the pressure difference between the large cover and the reactor is large, and the bottom plate of the large cover is stretched and deformed, causing the deformation of the feeding sleeve, the evacuation tube sleeve and the vacuum channel tube, not only The air intake of the titanium sponge affects the product quality, the use efficiency of the large cover is low, and the technical problems of increasing the labor intensity of the operator
