The height of the crucible embedded in a heat source can be adjusted so that the crucible can be used for distilling of various rare-earth metals.
Description
Technical field
The utility model relates to a kind of tantalum material multistage distillation crucible, the extraordinary material distillation crucible that uses when being rare earth metal vacuum distillation purification.
Term in the patent specification " multistage " is meant, when crucible is embedded in height in the heater when different, the temperature difference that forms between crucible upper outlet and crucible bottom is also different.Adopt the different temperature difference owing to produce different metal needs, so carry out multistage distillation by forming the multistage temperature difference.
Term in the patent specification " thermograde " is meant, thermal insulation board upper temp and crucible bottom temperature poor.
Background technology
Vacuum distillation method is according to rare earth metal and impurity element vapour pressure and evaporation rate different under different temperatures, reaches the purpose of rare earth metal and separation of foreign elements.
In the prior art, the height that crucible is embedded in the heater is fixed, and the temperature difference that forms between crucible upper outlet and crucible bottom is not easy to change, and therefore, produces different metals and just must adopt different crucibles.Therefore, the crucible of a series of different size must be prepared by enterprise.Yet crucible material is the tantalum material, and cost is higher; And because the outlet size on the crucible is less, the big reguline metal crucible of can't packing into must fragmentation just can distill operation.
The utility model content
The purpose of this utility model provides a kind of tantalum material multistage distillation crucible, its height that is embedded in thermal source can be conditioned, can form the suitable temperature difference in the various rare earth metal metallurgy purification process between the upper outlet of crucible and the bottom of crucible, make a crucible can be used for distilling various rare earth metal.
For this reason, the utility model provides a kind of tantalum material multistage distillation crucible, and described distillation crucible comprises a pot body, thermal insulation board and receiving hood; Described thermal insulation board is set in the upper end of pot body, and receiving hood is arranged on the top of described pot body, is positioned at the top of thermal insulation board; Described pot body is made by tantalum, is up-small and down-big trumpet type Rotary-table shape; Described thermal insulation board is made by refractory material high temperature resistant and that heat-proof quality is good, it is characterized in that, described thermal insulation board comprise can stacked use the polylith thermal insulation board; Being provided with multi-disc in heater can be at the pad of the stacked use in the bottom of crucible.
Preferably, the thickness of described pot body is 2～3mm.
Preferably, the last bore of described pot body is 100～250mm, bore is that 300～500mm, height are 250～400mm down.
According to multistage distillation crucible of the present utility model, because the rare earth metal high temeperature chemistry is active strong, very easily react with other material, the pot body selects for use strong, the corrosion resistant rare metal tantalum of chemical stability material to make, and can prevent the pollution once more that crucible impurity may cause product in the distillation purification process.
According to multistage distillation crucible of the present utility model, its up-small and down-big scalene cone structure can be blocked different radiations heat energies, thereby make the receiving hood at crucible top and the pot body of thermal insulation board bottom form the different temperature difference, different distillation melting point metal differences is also different to the reception temperature requirement in the receiving hood (condensing zone).
According to tantalum material multistage distillation crucible of the present utility model, main body is embedded in the heater, and crucible top isolates by refractory material (thermal insulation board), blocks radiation and conduction heat, thereby form condensing zone in the receiving hood of top, the metal that distills receives in the receiving hood of top condensing zone.
According to tantalum material multistage distillation crucible of the present utility model, regulate the height of crucible in heater by increasing or reduce pad, and/or adjust the temperature of condensation reception area, thereby can distill purification to the metal of different melting points and different vapour pressures by the piece number of adjusting thermal insulation board.
According to tantalum material multistage distillation crucible of the present utility model, in use, the rare earth metal that the desire distillation is purified places crucible bottom, put heating in the heater into, the rare earth metal of low melting point, high-vapor-pressure receives in condensing zone, and the foreign metal of high-melting-point, low-steam pressure then remains in the crucible.
Description of drawings
Fig. 1 is the structural representation according to tantalum material multistage distillation crucible of the present utility model.
The specific embodiment
As shown in Figure 1, according to tantalum material multistage distillation crucible of the present utility model, comprise pot body 1, several layers thermal insulation board 2 and receiving hood 3.Thermal insulation board 2 is arranged on the upper end of pot body 1, and receiving hood 3 is arranged on the top of thermal insulation board 2.
This pot body 1 is the pagoda type shape, promptly is up-small and down-big trumpet type Rotary-table, and its top is provided with one or more layers thermal insulation board 2, and the top of thermal insulation board 2 is provided with receiving hood 3.Described pot body 1 is made by the tantalum material, and thickness is 2～3mm, and last bore is 100～250mm, following bore is 300～500mm, height is the Rotary-table of 250～400mm, and its up-small and down-big ramp structure also helps to block different radiations heat energies, thereby forms different thermogrades.
According to multistage distillation crucible of the present utility model, in use, regulate the height of crucible in heater 6 by increasing or reduce pad 5, can carry out different distillations to the metal of different melting points and different vapour pressures and purify, adjust the temperature of condensation reception area by the piece number of adjusting thermal insulation board 2; The rare earth metal 4 that distillation is purified places crucible bottom, put heating in the heater 6 into, by behind this device, the rare earth metal of low melting point, high-vapor-pressure can receive in different condensing zone (receiving hood 3) by thermograde, and the foreign metal of high-melting-point, low-steam pressure then remains in the crucible.
The utility model makes by three kinds of modes and produces the temperature difference between pot body 1 and the condensing zone (receiving hood 3): by crucible up and down between the inclined-plane of trumpet type block radiations heat energy; Block radiations heat energy by thermal insulation board; And the refractory material that adopts high temperature resistant and difficult conduction heat blocks the radiations heat energy of pot body as thermal insulation board, makes in pot body different with the reception case temperature.
The distillation crucible is welded for the tantalum material, and tantalum piece thickness is generally 2～3mm.The crucible main body is embedded in the thermal treatment zone 6, and crucible top isolates by refractory material, blocks radiation and conduction heat, thereby makes top form condensing zone, and the metal that distills receives in the receiving hood of top condensing zone.
When the fusing point that the crucible distillation is different and the metal of different vapour pressures, multistage temperature difference control method:
A) by increasing or reducing pad, regulate the height of crucible in heater;
B) adjust condensation reception area temperature by adjusting the insulating block number.
