Abstract
The utility model discloses a kind of porous graphite crucibles, including crucible body, crucible body is provided centrally with crucible through-hole, several reacting holes are provided with centrosymmetric in crucible body, the crucible through hole is provided with cartridge heater, and the cartridge heater and crucible via clearance are arranged, venthole is provided with above cartridge heater, the side wall of cartridge heater is provided with thermal hole, and cartridge heater pedestal is provided with below cartridge heater, and crucible body is provided with snap ring under crucible tongs upper snap ring, crucible tongs.The utility model has the following beneficial effects: reducing the preheating time of porous graphite crucible, the service life of crucible body is increased, crucible clamp is easy to use to carry.
Description
Technical field
The utility model relates to graphite crucible apparatus field, especially a kind of porous graphite crucible.
Background technique
The body material of graphite crucible is the natural graphite of crystalline, so graphite crucible has good thermal conductance and resistance to
High temperatures, during applied at elevated temperature, thermal expansion coefficient is small, has certain stain resistance for chilling, anxious heat, simultaneously for
Acid, the corrosion resistance of aqueous slkali are stronger, have excellent chemical stability, ensure that the purity for being smelted object.Porous graphite earthenware
Crucible is usually used in smelting, negative electrode material and the semiconductor material production technology of metal.
In the prior art, porous graphite crucible needs slowly to be baked to 500 degrees centigrades before use and can use, and
It needs that Strong oxdiative flame is avoided to be directly injected on porous graphite crucible, influences its service life, this results in preheating slowly to increase
The production cycle for being smelted object is added.
Utility model content
The purpose of this utility model, which is that, overcomes above-mentioned deficiency, provides a kind of porous graphite crucible.
In order to achieve the above objectives, the utility model is implemented according to following technical scheme:
A kind of porous graphite crucible, including crucible body, crucible body are provided centrally with crucible through-hole, in crucible body
Several reacting holes are provided with centrosymmetric, the crucible through hole is provided with cartridge heater, the cartridge heater and crucible through-hole
Gap setting is provided with venthole above cartridge heater, and the side wall of cartridge heater is provided with thermal hole, is provided with below cartridge heater
Cartridge heater pedestal.
Further, it is provided with bottom tub below the crucible body, bottom tub matches with cartridge heater pedestal.
Further, the cartridge heater pedestal is connected through a screw thread with crucible body.
Further, the unilateral gap distance between the cartridge heater and crucible through-hole is 10-100 millimeters.
Further, the upper limb of the crucible body is provided with crucible tongs upper snap ring, is arranged close to the bottom of crucible body
There is snap ring under crucible tongs.
Compared with prior art, the porous graphite crucible of the utility model preheating when, can be used flame against plus
Hot cylinder pedestal injection, a part of flame are internally heated porous graphite crucible by the thermal hole of cartridge heater, reduce more
Hole graphite crucible preheating time；Cartridge heater and crucible body are threadedly coupled simultaneously, when cartridge heater because adding heat-induced damage can
With quick-replaceable, the service life of crucible body is increased；Snap ring is easy to use crucible card under crucible tongs upper snap ring and crucible tongs
Pincers carry crucible body.The utility model has the following beneficial effects: reducing the preheating time of porous graphite crucible, increase
The service life of crucible body is easy to use crucible clamp to carry.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings and specific embodiments, in the signal of this utility model
Property embodiment and explanation be used to explain the utility model, but be not intended to limit the scope of the present invention.
The crucible that is provided centrally with of a kind of porous graphite crucible as shown in Figure 1, including crucible body 1, crucible body leads to
Hole 2 is provided with several reacting holes 3 with centrosymmetric in crucible body, and the crucible through hole is provided with cartridge heater 4, described
Cartridge heater and crucible via clearance are arranged, and are provided with venthole 5 above cartridge heater, and the side wall of cartridge heater is provided with thermal hole 6,
The aperture of thermal hole is greater than venthole, is provided with cartridge heater pedestal 7 below cartridge heater.
Further, it is provided with bottom tub 8 below the crucible body, bottom tub matches with cartridge heater pedestal；It is described
Cartridge heater pedestal is connected through a screw thread with crucible body；Unilateral gap distance between the cartridge heater and crucible through-hole is 10-
100 millimeters；The upper limb of the crucible body is provided with crucible tongs upper snap ring 9, and the bottom close to crucible body is provided with crucible tongs
Lower snap ring 10.
The cartridge heater of the utility model is vulnerable part, and cartridge heater passes through cartridge heater pedestal and the crucible body side of threaded connection
Formula realizes that quick-replaceable, cartridge heater play a protective role to crucible body；Snap ring facilitates earthenware under crucible tongs upper snap ring, crucible tongs
Crucible clamp fix crucible body, and are unlikely to cause crucible body local pressure is excessive to cause to shorten the working life.
The limitation that the technical solution of the utility model is not limited to the above specific embodiments, all skills according to the present utility model
The technology deformation that art scheme is made, each falls within the protection scope of the utility model.
