Description
Technical field
This utility model relates to a kind of electric heating crucible, belongs to teaching equipment field.
Background technology
Crucible is the important component part of chemical apparatuses, and it is fusing and refined metals liquid and solid-liquid heating, reacts
Container, be to ensure that the basis that chemical reaction is smoothed out.The model specification of crucible is more, application time not by production scale,
Batch size and the restriction of melting material kind, can arbitrarily select, and the suitability is relatively strong, and can ensure to be smelted the purity of material.
But existing crucible needs to be stirred in heating process so that heated is heated evenly in crucible, but in stirring
During, heated is it some times happens that splash in melting process, and user is injured.
Utility model content
The deficiency existed for prior art, technical problem to be solved in the utility model is to provide a kind of electrical heating
Crucible, easy to use, prevent user injured when occurring and splashing.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of electric heating crucible, including crucible
Body, crucible body top is provided with crucible cover, is provided with crucible cavity in crucible body, and the bottom surface of crucible cavity is circular；Described earthenware
Crucible body lower end is internally provided with heating chamber I, and the heating that the lower surface of crucible cavity is provided with some annulars is protruding, heating projection
Arranging in concentric circular, heating is provided with electrical heating wire in chamber I；It is provided with heating chamber II in described crucible body sidewall, heats chamber II
Inside being provided with electrical heating wire, crucible body sidewall outer surface is provided with power interface, power interface connects electrical heating wire；Described earthenware
Being provided with some conical pipes on crucible cavity inner wall, conical pipe UNICOM heating inner space, chamber II, the tapering of conical pipe is 1:0.87；
The 1/8 of the height that distance is crucible cavity of top to the crucible cavity bottom surface that described heating is protruding.
Optimizing, above-mentioned electric heating crucible, the bottom surface that distance is crucible cavity of described two adjacent heating projections is straight
The 1/9 of footpath.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.The application's
Design is by electric heating crucible, and firing rate is faster than the open firings such as alcohol burner.In order to increase firing rate further, at crucible
The heating arranging annular on the lower surface of cavity is protruding, increases the contact area of compound to be heated and crucible cavity inner wall, and
And add homogeneous heating degree.Conventional electric heating crucible generally uses bottom-heated mode, and this mode of heating steam floats,
Heat is scattered and disappeared.Existing heated sealed crucible is usually large-scale crucible, and cannon pot is because need to stir in heating process
Mix, it is impossible to use sealing means.Therefore the application scatters and disappears to make up this partial heat, adds heating chamber II and conical pipe,
Heated air in heating chamber II is delivered to crucible empty intracavity by conical pipe, accelerates firing rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1；
In figure: 1 be crucible body, 2 be crucible cover, 3 be crucible cavity, 4 protruding for heating for heating chamber I, 5,6 be electrical heating
Silk, 7 for heating chamber II, 8 be power interface, 9 be conical pipe.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
This utility model is a kind of electric heating crucible, and including crucible body, crucible body top is provided with crucible cover, in crucible body
Being provided with crucible cavity, the bottom surface of crucible cavity is circular；Described crucible body lower end is internally provided with heating chamber I, crucible cavity
Lower surface on to be provided with the heating of some annulars protruding, heating is protruding arranges in concentric circular, and heating is provided with electrical heating in chamber I
Silk；Being provided with heating chamber II in described crucible body sidewall, heating is provided with electrical heating wire, on crucible body sidewall outer surface in chamber II
Being provided with power interface, power interface connects electrical heating wire；It is provided with some conical pipes, conical pipe on described crucible cavity inner wall
UNICOM's heating inner space, chamber II, the tapering of conical pipe is 1:0.87；The top of described heating projection is to crucible cavity bottom surface
The 1/8 of the height that distance is crucible cavity.The basal diameter that distance is crucible cavity that described two adjacent heating are protruding
1/9。
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.The application's
Design is by electric heating crucible, and firing rate is faster than the open firings such as alcohol burner.In order to increase firing rate further, at crucible
The heating arranging annular on the lower surface of cavity is protruding, increases the contact area of compound to be heated and crucible cavity inner wall, and
And add homogeneous heating degree.Conventional electric heating crucible generally uses bottom-heated mode, and this mode of heating steam floats,
Heat is scattered and disappeared.Existing heated sealed crucible is usually large-scale crucible, and cannon pot is because need to stir in heating process
Mix, it is impossible to use sealing means.Therefore the application scatters and disappears to make up this partial heat, adds heating chamber II and conical pipe,
Heated air in heating chamber II is delivered to crucible empty intracavity by conical pipe, accelerates firing rate.The taper optimized
Pipe, heating projection are to coordinate the volume of crucible body to arrange, and can accelerate firing rate and can through verification experimental verification
Protect additional heat as soon as possible to run off.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, this
The those of ordinary skill of technical field, in essential scope of the present utility model, the change made, retrofits, adds or replaces, all
Protection domain of the present utility model should be belonged to.
