Description

Technical Field

[0001] This utility model relates to a production apparatus for sponge titanium, and particularly to a moisture evaporation device for a cold-end system in sponge titanium production. Background Technology

[0002] Industrial production of sponge titanium employs the magnesium reduction of titanium tetrachloride method. Most furnaces utilize a combined inverted "U"-shaped production process, characterized by high single-furnace output, high yield of superior-grade products, and low energy consumption. The inverted "U"-shaped combined production process mainly consists of a hot-end system and a cold-end system. Both systems comprise reactors and a cover. The hot-end system primarily involves the reduction of titanium tetrachloride with magnesium at high temperatures to produce magnesium chloride and sponge titanium. After reduction, a distillation stage is initiated, where a cold-end system is connected via a passageway next to the hot-end system for distillation. The magnesium and magnesium chloride from the hot-end system are distilled into the cold-end system, yielding pure sponge titanium. Before assembling the cold-end system, the cover requires acid washing, resulting in moisture accumulation on its surface. At room temperature, the reactor has a small amount of low-valence compounds adhering to its inner wall, which absorbs moisture when exposed to air. If the cover and reactor are assembled into a cold-end system, the presence of moisture will affect product quality. This paper provides a heating device for the cold-end system in sponge titanium production to improve product quality. Utility Model Content

[0003] This invention aims to solve the technical problem of a small amount of moisture in the cold end system affecting product quality.

[0005] A moisture evaporation device for a cold-end system in sponge titanium production mainly consists of a large cover and a reactor, with a sealing gasket between the large cover and the reactor.

[0006] The lower flange of the reactor is connected to the flange of the heating device, and a sealing gasket is provided between the lower flange of the reactor and the flange of the heating device.

[0014] 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.

[0015] like Figure 1 As shown, a water evaporation device for a cold end system in the production of sponge titanium mainly consists of a large cover 1 and a reactor 2, with a sealing gasket between the large cover 1 and the reactor 2.

[0016] The lower flange of the reactor 2 is connected to the flange of the heating device 4, and a sealing gasket 3 is provided between the lower flange of the reactor 2 and the flange of the heating device 4.

[0017] The large cover 1 is equipped with a vacuum tube 5 and a temperature measuring tube 8. A valve C6 and a pressure gauge B7 are installed on the vacuum tube 5.

[0018] The heating device 4 has a heat preservation effect and is mainly composed of a heat inlet pipe 4.1, valve A 4.2, air outlet pipe 4.3, valve B 4.4 and pressure gauge A 4.5.

[0019] During the assembly of the cold-end system, the large cover 1 and reactor 2 are connected to the heating device 4 to form the cold-end system. A sealing gasket 3 is installed between the lower flange of reactor 2 and the flange of heating device 4. Valve C6 is opened, and vacuum pipe 5 is connected to the evacuation system for evacuation. When pressure gauge B7 shows 100 Pa, heat inlet pipe 4.1 is connected to the heat pipe of the reduction production process. When the temperature measuring pipe 8 measures 100℃ and maintains it for 2 hours, valve B4.4 on outlet pipe 4.3 is closed, and pressure gauge A4.5 is maintained at 20 kPa. Valve A4.2 is then closed, and evacuation continues for another 3 hours. Under the heating and vacuum environment, the moisture in the cold-end system is completely removed, ensuring the production quality of sponge titanium.
