Abstract
The invention discloses a double-layer thermal insulation crucible. The crucible comprises an outer crucible body. An inner crucible body is arranged in the outer crucible body. The lower end face of the internal wall of the outer crucible body is in a round shape. The lower end face of the external wall of the inner crucible body is in a round shape. An annular first partition plate is arranged between the lower end face of the internal wall of the outer crucible body and the lower end face of the external wall of the inner crucible body; an annular second partition plate is arranged between the lower part of the external wall of the inner crucible body and the lower part of the internal wall of the outer crucible body; and the upper edges of the outer crucible body and the inner crucible body are in a same plane. The provided thermal insulation crucible has the advantages that the shortages of prior art are overcome, and the structural design is novel and reasonable.
Description
Technical field
The present invention relates to a kind of double thermal insulation crucible, belong 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, the container of reaction, is to ensure that the basis that chemical reaction is smoothed out.The model specification of crucible is more, is not limited by production scale, batch size and melting material kind when application, can arbitrarily select, and the suitability is relatively strong, and can ensure to be smelted the purity of material.When classroom instruction is tested, after using crucible to do experiment, it is sometimes desirable to crucible is picked up and shows to student, but crucible temperature after heating is the highest, it is desirable to pick up displaying has inconvenience more.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide a kind of double thermal insulation crucible, and convenient teaching displaying uses.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of double thermal insulation crucible, including outer crucible body, is provided with interior crucible body in outer crucible body, and the inwall lower surface of outer crucible body is circular, and the outer wall lower surface of interior crucible body is circular；It is provided with the first division board of annular between outer wall lower surface and the inwall lower surface of outer crucible body of described interior crucible body, between outer wall bottom and the inner wall lower of outer crucible body of interior crucible body, is provided with the second division board of annular；The upper edge of described outer crucible body and the upper edge of interior crucible body are in the same plane；An arc groove it is provided with on the outer wall lower surface of described outer crucible body, the radian of arc groove is 2.76, the A/F of arc groove is the 7/8.5 of the inwall lower surface diameter of outer crucible body, the outer wall lower surface of interior crucible body be arranged in parallel with the inwall lower surface of outer crucible body, distance is interior crucible height 1/6.5 between outer wall lower surface and the inwall lower surface of outer crucible body of interior crucible body；It is provided with some finger recesses on the external wall of described outer crucible.
Optimize, above-mentioned double thermal insulation crucible, in the described space surrounded by the second division board, the inwall of outer crucible body, the outer wall of interior crucible body, be filled with insulating layer of asbestos.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.Carrying out teaching displaying in order to the most conveniently pick up, crucible is set to the form of two crucible bodies by the design of the application.But this form can affect the heats of crucible body, therefore the technical scheme of the application adds the first division board, is separated with upper portion side wall by bottom heating location, and on the outer wall lower surface of outer crucible body, it is provided with an arc groove, increases heats.Being communicated up to isolate the temperature of bottom heating, the design of the application adds the second division board, it isolate an isolation cavity, prevent heat to be communicated up.In order to increase effect of heat insulation further, in the space surrounded by the second division board, the inwall of outer crucible body, the outer wall of interior crucible body, it is filled with insulating layer of asbestos.

Fig. 2 be Fig. 1 look up structural representation；
Fig. 3 is the internal structure schematic diagram of the present invention；
In figure: 1 be outer crucible body, 2 be interior crucible body, 3 be the first division board, 4 be the second division board, 5 be arc groove, 6 be finger recess, 7 for insulating layer of asbestos.
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.
The present invention is a kind of double thermal insulation crucible, including outer crucible body, is provided with interior crucible body in outer crucible body, and the inwall lower surface of outer crucible body is circular, and the outer wall lower surface of interior crucible body is circular；It is provided with the first division board of annular between outer wall lower surface and the inwall lower surface of outer crucible body of described interior crucible body, between outer wall bottom and the inner wall lower of outer crucible body of interior crucible body, is provided with the second division board of annular；The upper edge of described outer crucible body and the upper edge of interior crucible body are in the same plane；An arc groove it is provided with on the outer wall lower surface of described outer crucible body, the radian of arc groove is 2.76, the A/F of arc groove is the 7/8.5 of the inwall lower surface diameter of outer crucible body, the outer wall lower surface of interior crucible body be arranged in parallel with the inwall lower surface of outer crucible body, distance is interior crucible height 1/6.5 between outer wall lower surface and the inwall lower surface of outer crucible body of interior crucible body；It is provided with some finger recesses on the external wall of described outer crucible.It is filled with insulating layer of asbestos in the described space surrounded by the second division board, the inwall of outer crucible body, the outer wall of interior crucible body.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.Carrying out teaching displaying in order to the most conveniently pick up, crucible is set to the form of two crucible bodies by the design of the application.But this form can affect the heats of crucible body, therefore the technical scheme of the application adds the first division board, is separated with upper portion side wall by bottom heating location, and on the outer wall lower surface of outer crucible body, it is provided with an arc groove, increases heats.Being communicated up to isolate the temperature of bottom heating, the design of the application adds the second division board, it isolate an isolation cavity, prevent heat to be communicated up.In order to increase effect of heat insulation further, in the space surrounded by the second division board, the inwall of outer crucible body, the outer wall of interior crucible body, it is filled with insulating layer of asbestos.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, those skilled in the art, in the essential scope of the present invention, the change made, retrofits, adds or replaces, all should belong to protection scope of the present invention.
