Description

Large cover with heat-preservation and heating function for titanium sponge distillation production

Technical Field

The utility model relates to a device that production titanium sponge was used specifically says so and relates to a big lid of titanium sponge distillation production usefulness of area heat preservation heating.

Background

At present, the industrial production of titanium sponge at home and abroad adopts a method for reducing titanium tetrachloride by magnesium. The method comprises the steps of adding liquid magnesium into a reactor, continuously adding titanium tetrachloride to react with the liquid magnesium to obtain granular titanium, slowly forming titanium sponge lump, after reduction charging production is finished, carrying out distillation production to remove a small amount of magnesium and magnesium chloride in the titanium lump, and adopting a distillation furnace type mode to comprise a series furnace and a parallel furnace (an inverted U-shaped combination method). In the reduction distillation production process, most furnace types are produced by adopting an inverted U-shaped combined method, and the method has the advantages of large yield, high qualification rate, low energy consumption, low labor cost and the like compared with a small single furnace. In order to improve the production quality of the titanium sponge and reduce the production cost, the large-scale equipment is taken as a technical development direction in all countries. The combined furnace parallel connection furnace is that a cold end reaction tank which is the same as a hot end system is connected with a horizontal pipe as a container for collecting magnesium and magnesium chloride by a passage (the passage is connected by a horizontal pipe and a vertical pipe in a welding way) arranged on a large cover in the prior art beside a reduction production furnace. Magnesium and magnesium chloride steam is distilled from a hot end system to a cold end system through a passageway, and in order to ensure that the high-temperature magnesium and the magnesium chloride steam are not condensed in the passageway, a vertical pipe heater and a transverse pipe heater are independently installed on a passageway vertical pipe above a large cover panel. The vertical pipe heater and the horizontal pipe heater are large in size, the overhead travelling crane is required to hoist each time the vertical pipe heater and the horizontal pipe heater are mounted and dismounted, and the operation of workers for butting the passage takes about 2 hours during assembling and dismounting; when heating, the heater is heated to above 850 ℃ to consume electric energy; during distillation, the welding of the vertical pipe and the transverse pipe is easy to generate cracks, and if leakage occurs, production has to be stopped and the product quality is affected; under the high-temperature and high-vacuum environment, the pressure difference between the inside of the passageway and the outside is large, so that the passageway is easy to deform, and the welding line is easily cracked by thermal stress, so that the production is stopped and the product quality is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a for solving exist among the prior art: 1. the heaters of the vertical pipe and the horizontal pipe of the large cover consume electricity; 2. the heater for the large-cover vertical pipe and the horizontal pipe is large in size; 3. the technical problem of high-temperature deformation is solved.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a large cover with heat preservation and heating functions for titanium sponge distillation production comprises a large cover bottom plate 1, a large cover cylinder 2, a large cover panel 4, a vertical pipe 5, a horizontal pipe 8, a circular plate 9 and an evacuation pipe 10; the circular ring plate 9 is arranged at the top end of the transverse pipe 8; the evacuation pipe 10 is arranged on the large cover panel 4; the method is characterized in that: a passage pipe 6 with a 90-degree radial angle is arranged in the large cover cylinder body 2, the vertical pipe 5 and the transverse pipe 8;

a heating element 7 is arranged on the outer pipe surface of the aisle pipe 6;

and a heat-insulating layer 3 is filled in a closed cavity formed by the large cover bottom plate 1, the large cover cylinder body 2, the large cover panel 4, the vertical pipe 5, the passageway pipe 6, the transverse pipe 8 and the circular plate 9.

Adopt above-mentioned technical scheme's beneficial effect:

1. the utility model discloses overcome big lid passageway welding quality problem, reduce the product probability of admitting air, improve titanium sponge production quality.

2. Adopt the utility model discloses the passageway heating reduces the power consumption cost than current big lid passageway heating technique.

3. Adopt the utility model discloses the passageway heating, manual assembly passageway heater when avoiding distilling reduces the operation operative employee's of overhead traveling crane intensity of labour.
