Abstract
The utility model discloses a vacuum distillation system for titanium sponge production. The system comprises a high-vacuum distillation filter (2) connected with a reduction reactor (1), wherein one end of the high-vacuum distillation filter (2) is connected with the reduction reactor (1), and the other end of the high-vacuum distillation filter (2) is connected with an oil diffusion pump (3) and a slide valve pump (4); and an intermediate pump (5) is arranged between the oil diffusion pump (3) and the slide valve pump (4). A Roots vacuum pump is added to serve as the connecting intermediate pump; the Roots vacuum pump can be started when the slide valve pump reaches the ultimate vacuum; and the oil diffusion pump can be started when the Roots vacuum pump reaches the ultimate vacuum. The equipment system runs smoothly, and the vacuum suction is effective and continuous, so as to greatly reduce the load of the oil diffusion pump in the vacuum distillation system; the service life of the oil diffusion pump is prolonged; the vacuum transition of vacuum distillation is steady, so that the top-grade product rate is increased; the distillation time is shortened, and the energy consumption is reduced; and the core hardening possibility of titanium sponge lumps is decreased.
Description
Technical field
The utility model relates to a kind of vacuum distilling system, particularly relate to a kind of titanium sponge produce in used vacuum distilling system, belong to the vacuum distillation plant technical field.
Background technology
The reduction distillation workshop needs constantly to use the high vacuum unit in the vacuum distilling stage, and the impurity (material except that titanium sponge) in " reduction reactor " is extracted out, and the vacuum distilling system is exactly the equipment that the impurity in the titanium sponge is released.Because the highest attainable vacuum of slide valve pump is 1.3 handkerchiefs, the highest attainable vacuum of oil diffusion pump is 5 * 10
-5Handkerchief, pressure difference span has 10 in the middle of it
4Doubly, totally unfavorable to the relay of back level oil diffusion pump, the several hours ability of starting that oil diffusion pump must be meaningless reaches puffing regimens reluctantly.
During this period, can't the impurity of inside reactor be aspirated, thereby make the meaningless prolongation of distillation time and do not have effect, the impurity during titanium sponge sticks together can't be separated out, and the stick together degree of hard-core of titanium sponge increases; Also increased energy consumption.
Summary of the invention
The purpose of this utility model is, used vacuum distilling system in a kind of titanium sponge production is provided.Reduce the load of vacuum distilling system oil diffusion pump; Prolong the oil diffusion pump life-span, make vacuum distilling vacuum tightness transition section steady, increase high-grade-goods rate; Shorten distillation time simultaneously, reduce the stick together probability of hard-core of titanium sponge.
The technical solution of the utility model: used vacuum distilling system during a kind of titanium sponge is produced, comprise the molecular distillation strainer that is connected with reduction reactor, molecular distillation strainer one end is connected with reduction reactor, and the other end is connected with slide valve pump with oil diffusion pump; Between oil diffusion pump and slide valve pump, be provided with intermediate pump.
In the used vacuum distilling system, described intermediate pump is a Roots vaccum pump in producing for aforementioned titanium sponge, and its final vacuum is 5 * 10
-2Handkerchief.
Compared with prior art, the utility model increases a Roots vaccum pump.Because the highest attainable vacuum of slide valve pump is 1.3 handkerchiefs, the highest attainable vacuum of oil diffusion pump is 5 * 10
-5Handkerchief, and the highest attainable vacuum of Roots vaccum pump is 5 * 10
-2Handkerchief is just in time as the intermediate pump of taking over from the past and setting a new course for the future.After slide valve pump is extracted into the limit, just in time satisfy the entry condition of Roots vaccum pump; And after Roots vaccum pump is extracted into the limit, satisfy the entry condition of oil diffusion pump.The device systems operation is very smooth and easy, and vacuum take-off can carry out effectively continuously, has significantly reduced the load of vacuum distilling system oil diffusion pump; Prolonged the oil diffusion pump life-span; Make vacuum distilling vacuum tightness transition section steady, increased high-grade-goods rate; Shorten distillation time, reduced energy consumption.Reduced the stick together probability of hard-core of titanium sponge.
The utility model is debugged trial run in Jinchuan group titanium sponge engineering, and has obtained good result of use.

Embodiment.
The utility model as shown in Figure 1.Used vacuum distilling system during a kind of titanium sponge is produced comprises the molecular distillation strainer 2 that is connected with reduction reactor 1, and molecular distillation strainer 2 one ends are connected with reduction reactor 1, and the other end is connected with slide valve pump 4 with oil diffusion pump 3; Between oil diffusion pump 3 and slide valve pump 4, be provided with intermediate pump 5.Described intermediate pump 5 is a Roots vaccum pump, and its final vacuum is 5 * 10
-2Handkerchief.
Principle of work of the present utility model
The utility model in conjunction with on-the-spot feedback opinion, improves on the vacuum distilling system-based of original design.Increase a Roots vaccum pump.Because the highest attainable vacuum of slide valve pump is 1.3 handkerchiefs, the highest attainable vacuum of oil diffusion pump is 5 * 10
-5Handkerchief, and the highest attainable vacuum of Roots vaccum pump is 5 * 10
-2Handkerchief is just in time as the intermediate pump of taking over from the past and setting a new course for the future.After slide valve pump is extracted into the limit, just in time satisfy the entry condition of Roots vaccum pump; And after Roots vaccum pump is extracted into the limit, satisfy the entry condition of oil diffusion pump.The device systems operation is very smooth and easy, and vacuum take-off can carry out effectively continuously, has significantly reduced the load of vacuum distilling system oil diffusion pump; Prolonged the oil diffusion pump life-span; Make vacuum distilling vacuum tightness transition section steady, increased high-grade-goods rate; Shorten distillation time, reduced energy consumption.Reduced the stick together probability of hard-core of titanium sponge.Vacuum distilling system after the improvement changes " reduction reactor " vacuum distilling system in reduction distillation workshop into " slide valve pump-Roots-oil diffusion pump " vacuum triplex by " slide valve pump-oil diffusion pump " two-stage (two-speed) pump.Thereby significantly reduce the load of vacuum distilling system oil diffusion pump; Prolong the oil diffusion pump life-span, made vacuum distilling vacuum tightness transition section steady, increased high-grade-goods rate; Shorten distillation time simultaneously, reduced the stick together probability of hard-core of titanium sponge.
