Large cover for preventing condensed magnesium from gathering in titanium sponge production

Abstract

A large cover for preventing condensed magnesium from gathering in titanium sponge production comprises a barrel arranged on the upper portion of a bottom plate, and a center channel pipe, an inner heater and a heat preservation layer are arranged on the bottom plate in the barrel. A panel is arranged at the upper part of the barrel; the bottom plate, the cylinder body, the panel and the central channel pipe form a closed space; a conductive rod sleeve is arranged on the panel, a conductive rod is arranged in the conductive rod sleeve, a heater is arranged at the lower end of the conductive rod, and the heater is arranged on the inner side face of the barrel; the heater is arranged on the upper portion of the bottom plate. When sponge titanium is reduced and distilled, the barrel body with the large cover is heated, so that the temperature of a gap between the inner wall of the reactor and the barrel body with the large cover is increased, and the technical problem of low gap temperature during distillation is solved. When sponge titanium is distilled, the temperature of the gaps is increased, so that magnesium steam is not condensed at the gaps and enters the condensation tank, and the production cost is saved. And the labor intensity of operators is reduced. The structure is simple and durable.

Description

Technical Field

[0001] This utility model relates to a production apparatus for sponge titanium, and particularly to a large cover used to prevent the accumulation of condensed magnesium in the production of sponge titanium. Background Technology

[0002] The production of sponge titanium employs the Krauer process. Molten magnesium is used in a sealed container consisting of a reactor and a large cover to reduce titanium tetrachloride, yielding titanium and magnesium chloride. Before the reduction distillation step, the reactor, large cover, and sieve plates are assembled. The sieve plates are installed at the bottom of the reactor, and the large cover is placed at the top, forming a sealed space. Liquid magnesium is used to reduce liquid titanium tetrachloride to obtain solid sponge titanium and liquid magnesium chloride. Magnesium chloride is discharged from the reactor at regular intervals, while the sponge titanium accumulates on the sieve plates to form titanium lumps. After the reduction process is completed, high-temperature, high-vacuum distillation is used to remove impurities such as magnesium chloride and magnesium from the titanium lumps, yielding pure sponge titanium. The main body of the reactor consists of an inner heater, a panel, a cylinder, a bottom plate, a vacuum channel tube, and an insulation layer. The inner heater, panel, cylinder, bottom plate, and reactor form a sealed space. During assembly, the cylinder of the reactor must extend into the reactor. To facilitate assembly, there is a certain gap between the inner wall of the reactor and the cylinder of the reactor. During distillation, due to the low temperature in this gap, a large amount of magnesium vapor and a small amount of magnesium chloride condense in the gap, forming a mixture of magnesium blocks and magnesium chloride. After distillation, the operator needs to peel off the condensed magnesium with a pneumatic pick, which increases the operator's labor intensity. The magnesium blocks are treated as waste, resulting in resource waste and increased production costs. Utility Model Content

[0003] This invention aims to solve the technical problem of magnesium condensation caused by the low temperature of the gap between the inner wall of the reactor and the cylinder of the large cover during distillation.

[0008] The heater is located on the upper part of the base plate. The beneficial effects of adopting the above technical solution are:

[0009] 1. This utility model realizes the heating of the cylinder of the large cover during the reduction distillation of sponge titanium, so as to increase the temperature of the gap between the inner wall of the reactor and the cylinder of the large cover, thus solving the technical problem of low gap temperature during distillation.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0016] A large cover used to prevent the accumulation of condensed magnesium in the production of sponge titanium includes a cylinder 2 on the upper part of a base plate 1, a central channel pipe 8, an inner heater 9 and an insulation layer 7 on the base plate 1 inside the cylinder 2; a panel 3 on the upper part of the cylinder 2; the base plate 1, cylinder 2, panel 3 and central channel pipe 8 form a sealed space; a conductive rod sleeve 4 is provided on the panel 3, a conductive rod 5 is provided inside the conductive rod sleeve 4, and a heater 6 is provided at the lower end of the conductive rod 5, with the heater 6 located on the inner side of the cylinder 2;

[0017] The number of conductive rod sleeves 4 is 2;

[0018] The number of conductive rods 5 is 2;

[0019] The heater 6 is located on the upper part of the base plate.

[0020] When the sponge titanium enters the distillation process, the central channel tube 8 is connected to the cold end system, and the vacuum pump in the cold end system is started. The conductive rod 5 is connected to the power system and energized. When the heater 6 reaches the distillation control temperature, the temperature of the gap between the inner wall of the reactor and the cylinder 1 of the large cover rises, preventing magnesium vapor from condensing there. The magnesium vapor then enters the cold end for condensation and collection through the central channel tube 8.

[0021] This invention enables the heating of the cylinder of the large lid during the reduction distillation of sponge titanium, thereby increasing the temperature of the gap between the inner wall of the reactor and the cylinder of the large lid, and solving the technical problem of low gap temperature during distillation.

[0022] It saves production costs and reduces the labor intensity of operators.
