Description
Technical field
The utility model relates to a kind of crucible for vacuum experiment field, especially a kind ofly works in the metallic crucible that can carry out vacuum seal and high-temperature heating in vacuum environment.
Background technology
Crucible is the important component part of chemical apparatuses, and it is the container of fusing and refined metals liquid and solid-liquid heating, reaction, is the guarantee chemical reaction basis of carrying out smoothly.Existing crucible is generally open design, can not meet some particular surroundings and requirement.
Caesium feedthrough system in a vacuum in property bundle injection experiments, requires that caesium evaporation forms steam, is entered in the vacuum chamber of ion gun place by pipeline with crucible heating liquid simple substance caesium.Crucible is operated in vacuum environment, requires certain vacuum seal, and crucible interior and external vacuum environment are come, and can carry out the interpolation of caesium simple substance at any time again to crucible simultaneously.And existing crucible can not complete requirement above.
Utility model content
The purpose of this utility model is to provide a kind of vacuum seal crucible, cannot ensure vacuum-packed problem when high-temperature heating to solve existing crucible.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of vacuum seal crucible, is characterized in that: include crucible body and crucible cover, is pressed with sealing ring between crucible body oral area and crucible cover; Crucible body oral area and crucible cover are all set to edge of a knife flange arrangement, and the two edge of a knife is relative; Crucible body oral area and crucible cover involutory after be fastened by bolts extruding, the two edge of a knife is cut described sealing ring respectively and is carried out vacuum seal; Include gas fairlead, described gas fairlead inserts from crucible cover and guides crucible body oral area into.
A kind of vacuum seal crucible, is characterized in that: described crucible body is cylindrical-shaped structure, crucible body oral area is provided with the edge of a knife flange arrangement of one.
A kind of vacuum seal crucible, is characterized in that: described sealing ring is metal o-ring.
A kind of vacuum seal crucible, is characterized in that: described gas fairlead is provided with flowmeter, metering valve or shutoff valve.
Crucible body and crucible cover are fastened by bolts extruding, and upper and lower two edges of a knife incision oxygen-free copper sealing ring carries out vacuum seal, also can carry out vacuum seal while making whole crucible to carry out high-temperature heating.Meanwhile, according to the needs of oneself, flowmeter, metering valve, shutoff valve etc. can be installed, control the switch of steam, flow velocity etc. at the extraction mouth of pipe.
The utility model advantage is:
The utility model combines metallic crucible with edge of a knife flange arrangement, realize high vacuum seal in high-temperature heating, works stable controlled.The utility model structure is simple, and working stability is reliable, and cost is lower, easy to process, installs succinct, can carry out high-temperature heating in vacuum environment to different material.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail
See accompanying drawing:
A kind of vacuum seal crucible, includes crucible body 1 and crucible cover 3, is pressed with sealing ring 2 between crucible body 1 oral area and crucible cover 3; Crucible body 1 oral area and crucible cover 3 are all set to edge of a knife flange arrangement, and the two edge of a knife is relative; Crucible body 1 oral area and crucible cover 3 involutory after be fastened by bolts extruding, the two edge of a knife is cut described sealing ring 2 respectively and is carried out vacuum seal; Include gas fairlead 4, described gas fairlead 4 inserts from crucible cover 3 and guides crucible body 1 oral area into.
Crucible body 1 the latter half is metal cylinder, and there is chamber inside, is used for holding heating object.By vertical heater, cylindrical body outer wall is heated, thus object in heating chamber.Crucible body the first half is the CF edge of a knife flange arrangement of integral type, and the edge of a knife hobs sealing ring.
In this example, crucible body is 304 stainless steels, and edge portions has 6 equally distributedly to run through screwed hole, and sealing ring is oxygen-free copper sealing ring.Crucible cover 3 is CF edge of a knife ring flange, and edge of a knife specification is consistent with crucible body, and in this example, the material of crucible cover is also 304 stainless steels, and there are 6 equally distributed through holes at crucible lid edge.4 is stainless steel fairleads, and the diameter of fairlead will be determined according to the diameter of crucible intracoelomic cavity, and in this example, 4 is external diameter 6mm, 304 stainless steel tubes of internal diameter 5mm.
In the caesium injected system of Neutral Beam Injection Experiment, this crucible is in vacuum environment, caesium simple substance is injected the inner chamber of crucible body, put sealing ring well, to good crucible cover, symmetrical loads onto 6 bolts, makes the upper and lower edge of a knife cut oxygen-free copper sealing ring by fastening bolt, tangent plane and the edge of a knife are close to extruding, isolated external vacuum.Then heated pot body wall by vertical tubular heating furnace, after being heated to three or four hundred degree, inner caesium simple substance forms steam continuously and enters ion gun vacuum chamber by fairlead.After caesium simple substance has heated, back out bolt, taken off lid, carried out the interpolation of caesium simple substance, then change sealing ring, again fastening bolt, then proceed test.
In actual use procedure, this crucible is highly suitable in higher vacuum environment and carries out high-temperature heating, the reliable and easy installation and removal of working stability.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, allly do not depart from enforcement of the present utility model or change, be all included in scope of patent protection of the present utility model.
