Technical Field

The invention relates to a device for producing titanium sponge, in particular to a device for realizing automatic hole forming and separated increase of the surface area of a titanium lump at the center of the titanium lump during the reduction production of the titanium sponge.

Background

At present, the industrial production of titanium sponge at home and abroad adopts a method for reducing titanium tetrachloride by magnesium. The method is characterized in that liquid magnesium is added into a reactor, titanium tetrachloride is continuously added to react with the liquid magnesium to obtain granular titanium, titanium sponge lumps are slowly formed, in the reduction distillation process, the furnace type is mostly produced by adopting an inverted U-shaped combination 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-furnace type 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. However, as the furnace type is increased, the volume of the titanium lump is increased, namely the mass of a single furnace is increased. The central part of the titanium lump is not easy to discharge in time, so that the central part of the titanium lump is sintered, the problems of excessive product sandwich MgCl2, large hard block amount, compact product structure and the like are intensively reflected at the central part of the titanium sponge lump, and the qualification rate and the grade rate of the product are seriously influenced. During distillation, the central part of the titanium lump is compact, the chloride at the central part is difficult to distill cleanly, a small amount of magnesium chloride and magnesium at the central part of the distilled titanium lump can occupy a large amount of distillation time, the power consumption is wasted, the production period is prolonged, and the production cost of the titanium sponge and the labor intensity of operators are increased. In the reduction process, the applicant develops a separation device (CN 104357686B) for producing titanium sponge in 2014, the titanium lump can be separated into a plurality of parts, the evaporation surface area of the titanium lump is increased, and the problems that the distillation time of the magnesium chloride at the center of the titanium sponge lump is long and the product structure is compact can be solved. However, because the titanium lump has large mass, about 12 tons of titanium lump is produced in each furnace, the separator cannot bear too large pressure under the high-temperature condition of nearly 1000 ℃, the separator is deformed and fails after being used for about 3 times, the deformed separator and the titanium lump are difficult to separate, and the labor intensity of operators is increased; the height of the separator is not too high due to process limitations, for example, too high, a bridging phenomenon is easily generated during the reduction reaction, and the production must be stopped after the bridging phenomenon occurs, so that the separator has limitations during the use.

Disclosure of Invention

The invention aims to solve the problems existing in the prior art that: 1. the divider cannot bear the weight; 2. the titanium lump produced by the conical device is difficult to separate and take out; 3. the evaporation surface area of the titanium lump is not large enough.

The specific implementation mode is as follows:

the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, a titanium lump central hole forming and separating device 2 for producing titanium sponge consists of a filter plate 201, a partition plate 202, a cone 203, a hoisting hole 204 and a titanium lump taking device 205; a cone 203 is arranged at the center of the filter plate 201; a hoisting hole 204 is arranged above the cone 203;

more than two partition plates 202 are uniformly welded on the filter plate 201 and the cone 203; a titanium lump taking-out device 205 is further arranged on the filter plate 201; the filter plate 201 and the cone 203 are integrally cast and formed, so that the structural stability of the device at high temperature can be better reflected.

As shown in fig. 3, a closed reduction distillation system is composed of a reactor 3 through a sealing gasket 5 and a large cover 6, a support frame 1 is placed at the bottom of the reactor 3, and a titanium lump central hole forming and separating device 2 is placed on the support frame 1.

When the reactor big cover 6 is assembled, the titanium lump central hole forming and separating device 2 is put on the support frame 1 in the reactor. During reduction feeding, fine titanium tetrachloride flows into the reactor 3 through the feeding pipe 7 and performs reduction reaction with the liquid magnesium 4, generated titanium sponge particles are deposited on the filter plate 201 to form a titanium lump, a titanium lump is formed around the titanium lump center hole and the titanium lump separation device 2 along with the feeding production, and under the action of the device, the titanium lump center hole forming and the titanium lump separation are automatically formed. When high constant temperature distills, cone 203 bears the weight of titanium lump well upper portion, has avoided titanium lump dead weight compression to lead to the titanium sponge compact structure and the device by pressure deformation scheduling problem. The surface area of the device is the increased evaporation surface area of the titanium lump. Therefore, compared with the prior art, the device increases the evaporation surface area of the titanium lump, shortens the generation period of the titanium sponge and reduces the energy loss; after the distillation, utilize the titanium that sets up on the filter plate 201 to stick together remove device 205, separate titanium stick together with the device very easily, reduced worker's intensity of labour.

In the device, the cone 203 mainly bears the high-temperature pressure, forms a hole in the center of the titanium lump and increases the evaporation surface area; the partition plate 202 mainly separates the titanium lump, increases the evaporation surface area, and makes the titanium lump and the device easier to separate and fall when finishing production.
