Abstract
The invention relates to a crucible. The crucible comprises a crucible body and a crucible cover and is characterized in that a ring of heat insulation layer is arranged on the outer surface of the crucible body, at least two lifting lugs are evenly distributed on the heat insulation layer located below the crucible cover, and an annular protrusion is arranged on the upper surface of the crucible cover and corresponds to the bottom of the crucible body. The crucible has the advantages that a user can take the crucible directly without crucible tongs and can be prevented from being scalded.
Description
Technical field
The present invention relates to chemical apparatuses technical field, particularly a kind of crucible.
Background technology
Crucible is the container that a kind of refractory material is made, and can be used for the calcination of solid matter, the evaporative crystallization etc. of solution.Crucible after being heated can not directly be placed on cold workbench, breaks because of quenching to avoid crucible; Also be not directly placed on wooden workbench, to avoid scorching the desktop that even ignites.In addition because crucible is in the condition of high temperature in use, make people take in productive life crucible time very inconvenient, the danger of scald may be caused when taking.
Summary of the invention
For the problems referred to above, the object of this invention is to provide one does not need to use crucible tongs, the crucible and can not being burned of can directly taking, and has the crucible of heat insulation support structure.
Realize technical scheme of the present invention as follows:
A kind of crucible, comprise crucible body and crucible cover, the outer surface of described crucible body is provided with a circle thermal insulation layer, and thermal insulation layer is evenly equipped with at least two hangers, this thermal insulation layer is positioned at below crucible cover; Described crucible cover upper surface is provided with annular protrusion, and the bottom of this annular protrusion and crucible body adapts.
Have employed above-mentioned scheme, when taking crucible, only need hold the hanger on thermal insulation layer or thermal insulation layer, so just can effectively prevent from being burned; Mouth of pot can not only be closed by crucible cover, can also play the effect of support crucible, particularly, prevented by crucible cover on table top, be then placed in annular protrusion by the bottom of crucible, such crucible would not scorch table top, also can not break because of quenching, safe and practical; Here annular protrusion not only serves the effect of installing crucible, and also can play the effect of mobile crucible lid, because also can be heated unavoidably during crucible heating, temperature uprises, and also can be burned.
The external diameter of described thermal insulation layer is consistent with the external diameter of crucible cover.
The bottom center place of described crucible body is provided with arc groove, crucible cover is provided with the arc convex adapted with arc groove, this arc convex is positioned at annular protrusion, described arc convex and annular protrusion concentric are arranged, advantage is that arc groove can make crucible bottom be heated evenly on the one hand, coordinate with arc convex on the other hand, crucible can be made to be positioned over stably in annular protrusion, prevent it from tilting to shake broken.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the first embodiment;
Fig. 3 is the second embodiment;
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Embodiment 1, as Fig. 1 and Fig. 2, a kind of crucible, comprise crucible body 1 and crucible cover 2, the outer surface of described crucible body 1 is provided with a circle thermal insulation layer 3, and thermal insulation layer adopts asbestos, thermal insulation layer 3 is evenly equipped with at least two hangers 4, this thermal insulation layer 3 is positioned at below crucible cover 2; Described crucible cover 2 upper surface is provided with annular protrusion 5, and this annular protrusion 5 adapts with the bottom of crucible body 1, and crucible body bottom is sidewall is arcuate structure, and the sidewall of annular protrusion is also arcuate structure, and the external diameter of thermal insulation layer 3 is consistent with the external diameter of crucible cover 2.
Embodiment 2, as Fig. 3, the bottom center place of described crucible body 1 is provided with arc groove 6, crucible cover 2 is provided with the arc convex 7 adapted with arc groove 6, and this arc convex 7 is positioned at annular protrusion 5, and described arc convex and annular protrusion concentric are arranged, advantage is that arc groove can make crucible bottom be heated evenly on the one hand, coordinate with arc convex on the other hand, crucible can be made to be positioned over stably in annular protrusion, prevent it from tilting to shake broken.
