Fig. 2 is the structural representation according to the metal titanium extraction plant of the utility model second embodiment.Compare with first embodiment, the structure of extraction plant and first embodiment are basic identical among second embodiment, give same symbol for identical parts, and detailed.
At this as shown in Figure 2, the difference of second embodiment and first embodiment is, also be provided with crucible 30 in the bottom of main body 10, and extraction agent 31 is contained in the inside of this crucible 30.Described crucible 30 generally is made of stainless steel or aluminum oxide material, and its shape can be the various shapes of being convenient to hold extraction agent 31 such as cylinder or polygon prism.
In addition, extraction plant according to second embodiment does not have the brace table 40 that adopts as first embodiment, but be provided with bracing frame 41 in the bottom of main body 10 with the form of separate part, to be used for described porous container 32 support arrangement in the inside of described main body 10.As long as can support described porous container 32, support frame as described above 40 can adopt arbitrary form.
Below, the embodiment shown in seeing figures.1.and.2 describes the working process of utilizing extraction plant of the present utility model to carry out the metal titanium extraction.
At first, extraction agent 31 is put into the bottom (as shown in Figure 1) of main body 10 or put into the inside (as shown in Figure 2) of the crucible 30 that is positioned at main body 10 bottoms.Then, the porous container 32 that titanium alloy to be extracted 33 is housed is fixed on the support component of main body 10 inside.At this, described support component can be brace table 40 or bracing frame as shown in Figure 2 41 as shown in Figure 1.Then, cover the upper opening of main body 10, thereby seal the internal space of described main body 10 with cover plate 11.Then, the internal space of main body 10 is vacuumized, and make refrigerant 21 flow into and flow out the internal space of cooling end 22 by refrigerant ingress pipe 23 and refrigerant delivery line 24.At this, need to prove when extraction plant does not have vapor pipe 51, vacuumize by 50 pairs of main bodys 10 of gas diversion tube, and when extraction plant also is provided with vapor pipe 51, can vacuumize by 51 pairs of main bodys 10 of this vapor pipe.Then, main body 10 heated make it to heat up, after temperature reached the fusing point of extraction agent 31, the steam of extraction agent 31 can rise rapidly, runs into cooling end 22, and the steam of extraction agent 31 will be condensate in the surface of cooling end 22.At this moment, the main body 10 inner argon gas that feed to vacuum, the extraction agent 31 that is condensate in cooling end 22 surfaces will drop onto on the porous container 32, titanium alloy to be extracted 33 reactions with the inside, titanium is wherein extracted, form liquid state, and fall into the bottom (as shown in Figure 1) of main body 10 or the inside (as shown in Figure 2) of crucible 30 by formed hole on the porous container 32.At this, need to prove no matter whether extraction plant have vapor pipe 51, all pass through main body 10 inner the feed argon gas of this gas diversion tube 50 to vacuum.After extraction finishes, cooling, the titanium alloy of this stylish formation is in the bottom (as shown in Figure 1) of main body 10 or the inside (as shown in Figure 2) of crucible 30, and original alloy is positioned at 32 li of porous containers.
In above-mentioned process, vacuumizing not is to be necessary step.It is in order to make extraction agent 31 easier evaporations when the heating that the inside of main body 10 is vacuumized, and be the better argon atmosphere of extraction construction of metal titanium.When extraction plant also is provided with vapor pipe 51, can vacuumize the internal space of main body 10.At this moment, import the argon gas of certain hour to the internal space of main body 10 by gas diversion tube 50, because the density of argon gas is greater than air, so importing along with argon gas, begin argon gas from the bottom of main body 10 inside and can replace air gradually, in this process, air can discharge by vapor pipe 51.
Below, explanation utilizes extraction plant shown in Figure 1 with reference to above-mentioned extraction process, the experimental example 1 that the Si-Fe-Ti alloy is extracted by the metal Pb extraction agent.
Get the Si-Fe-Ti alloy that 120g prepares, be placed in the porous container 32, the 250 gram metal Pb of weighing simultaneously join the bottom of main body 10.Under vacuum condition, heat up, when reaching the temperature of reaction (800 ℃), in main body, feed argon gas, made in the argon atmosphere that is reflected under the normal pressure reaction 2 hours, cool, thereby obtain the Pb-Ti alloy.Chemical analysis is carried out in sampling, and this alloy shows that through chemical analysis containing Ti is 11.98%, and Pb is 87.89%.Calculate according to chemical analysis results, this reaction, extraction efficient is 83%.
Below, explanation utilizes extraction plant shown in Figure 2 with reference to above-mentioned extraction process, the experimental example 2 that the Sn-Ti alloy is extracted by the Metal Zn extraction agent.
Get 130 and restrain the Sn-Ti alloy of getting ready, be placed in the porous container 32, the 250 gram Metal Zn of weighing simultaneously join in the crucible 30.Under vacuum condition, heat up, when reaching the temperature of reaction (800 ℃), in main body, feed argon gas, made in the argon atmosphere that is reflected under the normal pressure reaction 2 hours, cool, thereby obtain the Zn-Ti alloy.Chemical analysis is carried out in sampling, and this alloy shows that through chemical analysis containing Ti is 13.67%, and Zn is 86.04%.Calculate according to chemical analysis results, this reaction, extraction efficient is 86%.
Because the fusing point of Pb and Zn is low and volatile, so the product P b-Ti alloy or the Zn-Ti alloy that above-mentioned experimental example can be obtained distill according to 800 ℃ to 1200 ℃ temperature under vacuum condition, metal titanium extracts the most at last.
Can learn in view of the above, need not the new and old titanium alloy in the main body is separated by extraction plant of the present utility model, and can obtain quite high extraction efficiency.
Although illustrated and described embodiment more of the present utility model, but those skilled in the art will be appreciated that: under the situation that does not break away from principle of the present utility model and spirit, can change these embodiments, wherein, scope of the present utility model limits in claim and equivalent thereof.
