Description
Technical field
The utility model belongs to technical field of production of sponge titanium, the large lid arrangement of reactor particularly in a kind of magnesium method titanium sponge production.
Background technology
All adopt magnesium processes (Kroll method) suitability for industrialized production titanium sponge both at home and abroad at present.Magnesium reduction process produces titanium sponge; under argon shield; in steel reactor, add liquid titanium tetrachloride and the disposable molten metal magnesium added reacts, generate titanium sponge and magnesium chloride, titanium sponge obtains the process of finished product titanium sponge after vacuum distilling is purified.In reduction distillation operation, type of furnace majority adopts inverse u shape integrated process to produce, there is single furnace output large, high-grade-goods rate is high, the advantages such as energy consumption is low, along with the increase of the type of furnace, the production unit of links increases all accordingly, the large lid of reactor is one of major equipment of reduction distillation operation, in actual production process, the large lid of reactor is for a long time in high vacuum, work under the condition of high temperature, stress effect, will gross distortion be there is in the base plate of large lid with less than 5 times, be attached thereto the reinforced sleeve pipe connect also to be out of shape thereupon, filling tube is easily made not insert use, in addition, due to bottom deformation, weld drawing crack is easily caused to be leaked, in reactor, vacuum tightness declines violent, titanium sponge titanium stick together product because of air mass decline or directly scrap, affect production cost and production schedule, as found to leak, must stop to produce, keep in repair, the large lid of each reactor generally wants to keep in repair 2 ~ 3 working dayss, not only add maintenance cost, and add the labour intensity of worker.
Utility model content
Have problems for solving in prior art, the utility model provides the large lid arrangement of reactor in a kind of titanium sponge production, solve reactor large lid bottom deformation during reduction distillation and cause the problems such as reinforced sleeve pipe place weld seam drawing crack, extend the work-ing life of large lid, reduce maintenance cost and the labour intensity of large lid, qualification rate and the quality of Sponge Titanium can be promoted.
The technical solution of the utility model is as described below:
The large lid arrangement of reactor in a kind of titanium sponge production, primarily of panel, cylindrical shell, base plate composition, panel is located at the top of cylindrical shell, base plate is located at the bottom of cylindrical shell, reinforced sleeve pipe is arranged on reactor covers greatly through panel, base plate, a hole is offered at the junction surface of described base plate and reinforced sleeve pipe, this hole place is provided with thin plate, reinforced sleeve pipe passes thin plate and is connected with light gauge welding, in the cavity that panel, cylindrical shell, base plate and thin plate are formed, be provided with thermal insulation layer, gauge of sheet is less than the thickness of base plate.
Described thin plate and base plate adopt welding process to be connected.
The hole that the junction surface of described base plate and reinforced sleeve pipe offers is circular hole.
In the utility model: utilize the large lid of reactor of the present utility model, when titanium sponge reduction reacts, due to reaction solution surface temperature higher (being generally about 950 DEG C), heat mainly through thermal radiation direct radiation on base plate, the temperature of base plate sharply rises, produce thermal stresses, base plate is caused to be the distortion of concaveconvex shape, the thermal stresses that base plate produces acts directly on thin plate, utilize most of stress that thin plate Absorbable rod bottom deformation produces, because sheet gauge is thinner, attachment weld between the survivable and reinforced sleeve pipe of stress that its distortion produces, thus reduce bottom deformation generation stress effect, when distilling, due to high temperature (being generally about 1000 DEG C), under high pressure under (about 2 handkerchiefs) condition, this effect is more obvious.
Advantage of the present utility model and beneficial effect:
The large lid bottom deformation of reactor during solving reduction distillation and the reinforced sleeve pipe place weld seam drawing crack problem caused, compared with the large lid of pre-existing reactors, its work-ing life can extend more than 6 to 8 times, significantly can reduce maintenance cost and the labour intensity of the large lid of reactor, the stability of reinforced sleeve pipe place solder design is strong, good reliability, reactor air inlet phenomenon can be reduced, thus promote qualification rate and the quality of Sponge Titanium.
Accompanying drawing explanation
Fig. 1 is the large lid arrangement schematic diagram of reactor in a kind of titanium sponge production of the present utility model;
In figure: 1-panel, 2-cylindrical shell, 3-base plate, 4-thin plate, 5-thermal insulation layer, 6-feed in raw material sleeve pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but should not be interpreted as that the scope of theme described in the utility model is only limitted to following embodiment at this point, do not departing from the above-mentioned technological thought situation of the utility model, all make according to ordinary skill knowledge and customary means various amendments, replacement and change, include in scope of the present utility model.
Embodiment one
As shown in Figure 1, the large lid arrangement of reactor in a kind of titanium sponge production, form primarily of panel 1, cylindrical shell 2, base plate 3, panel 1 is located at the top of cylindrical shell 2, base plate 3 is located at the bottom of cylindrical shell 2, reinforced sleeve pipe 6 is arranged on reactor covers greatly through panel 1, base plate 3, a hole is offered with the junction surface of reinforced sleeve pipe 6 at described base plate 3, this hole place is provided with thin plate 4, reinforced sleeve pipe 6 passes thin plate 4 and is welded to connect with thin plate 4, in the cavity that panel 1, cylindrical shell 2, base plate 3 and thin plate 4 are formed, be provided with thermal insulation layer 5, the thickness of thin plate 4 is less than the thickness of base plate 3.
Described thin plate 4 adopts welding process to be connected with base plate 3.
The hole offered at described base plate 3 and the junction surface of reinforced sleeve pipe 6 is circular hole.
Utilize the utility model, when titanium sponge reduction reacts, due to reaction solution surface temperature higher (being generally about 950 DEG C), heat mainly through thermal radiation direct radiation on base plate 3, the temperature of base plate 3 sharply rises, produce thermal stresses, cause the distortion of base plate 3 in concaveconvex shape, the thermal stresses that base plate 3 produces acts directly on thin plate 4, thin plate 4 Absorbable rod base plate 3 is utilized to be out of shape the most of stress produced, due to thin plate 4 thinner thickness, attachment weld between the survivable and reinforced sleeve pipe 6 of stress that its distortion produces, thus reduce base plate 3 distortion generation stress effect, when distilling, due to high temperature (being generally about 1000 DEG C), under high pressure under (about 2 handkerchiefs) condition, this effect is more obvious.The large lid of reactor of the present utility model is compared with the large lid of pre-existing reactors, and its work-ing life can extend more than 6 to 8 times.
