Abstract
The utility model relates to a crucible, including crucible body and crucible lid, its characterized in that: be equipped with the round insulating layer on the surface of crucible body, the equipartition has two at least lugs on the insulating layer, and this insulating layer is located crucible lid below, crucible covers the surface and is equipped with the annular arch, and the protruding bottom with the crucible body of this annular suits. The utility model has the characteristics of need not use crucible pincers, can directly take crucible and can not be scalded etc.
Description
Technical field
The utility model relates to chemical apparatus technical field, in particular to a kind of crucible.
Background technology
Crucible is the container that a kind of refractory materials is made, and can be used for the evaporative crystallization etc. of the calcination of solid matter, solution. Crucible after being heated can not directly be placed on cold worktable, to avoid crucible to break because of quenching; Also not directly it is placed on wooden worktable, to avoid scorching the desktop that even ignites. In addition owing to crucible is in the condition of high temperature in use, make people produce life in take crucible time very inconvenient, the danger of scald may be caused when taking.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide one not to be needed to use crucible tongs, can directly take crucible and can not be burned, and have the crucible of heat insulation support structure.
Realize the technical solution of the utility model as follows:
A kind of crucible, comprises crucible body and crucible cover, and the outside surface of described crucible body is provided with a circle thermofin, and thermofin is evenly equipped with at least two hangers, and this thermofin 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 to hold the hanger on thermofin or thermofin, so just can effectively prevent from being burned; Crucible mouth can not only be closed by crucible cover, moreover it is possible to plays the effect of support crucible, specifically, being 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 installing crucible, it is also possible to play the effect of mobile crucible lid, because also can be heated unavoidably during crucible heating, temperature becomes high, also can be burned.
The external diameter of described thermofin 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, it is possible to crucible is positioned in annular protrusion stably, prevent it from tilting to shake broken.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the first embodiment;
Fig. 3 is the 2nd kind of embodiment;
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated further.
Embodiment 1, such as Fig. 1 and Fig. 2, a kind of crucible, comprising crucible body 1 and crucible cover 2, the outside surface of described crucible body 1 is provided with a circle thermofin 3, and thermofin adopts asbestos, being evenly equipped with at least two hangers 4 on thermofin 3, this thermofin 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 thermofin 3 is consistent with the external diameter of crucible cover 2.
Embodiment 2, such 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, it is possible to crucible is positioned in annular protrusion stably, prevent it from tilting to shake broken.
