Abstract
The invention discloses a thermal insulation heating crucible. The crucible comprises a crucible body. The lateral wall of the crucible body is in a cylinder shape. The lower part of the crucible body is provided with a horizontal end. A crucible cavity is arranged in the crucible body. An annular embossment is arranged on the internal wall of the crucible cavity. An upper cover plate is arranged on the annular embossment. The upper cover plate comprises a cover plate (I) and a cover plate (II). The cover plate (I) and the cover plate (II) are pivotedly joined. An arc groove is arranged in the lower surface of the horizontal end. The radian of the arc groove is 2.27. Multiple annular cavities, which are parallelly arranged, are arranged in the lateral wall of the crucible body. The distance between annular cavities is 1/10 of the height of crucible body. The provided thermal insulation heating 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 Heat preservation 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, use crucible to do experiment, owing to condition limits, do not have high temperature heat source, crucible heating slowly, to have impact on the progress of classroom instruction.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide a kind of Heat preservation crucible, prevents heat to scatter and disappear, accelerates heating progress.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of Heat preservation crucible, including crucible body, the sidewall of crucible body is cylindrical barrel, and the bottom of crucible body is provided with horizontal ends, and crucible body is internally provided with crucible cavity；Being provided with annular projection on described crucible cavity inner wall, annular projection is provided with upper cover plate, upper cover plate includes cover plate I and cover plate II, cover plate I and cover plate II pivot joint；Being provided with an arc groove on described horizontal ends lower surface, the radian of arc groove is 2.27；Being provided with some ring cavities be arrangeding in parallel in the sidewall of described crucible body, the spacing of ring cavity is the 1/10 of crucible height；Being provided with connection cavity between described two adjacent toroidal cavities, be provided with connecting tube between the ring cavity and arc groove of horizontal ends, connecting tube is cylindrical cavity, connects cavity and is perpendicular to arcuate recess surface.
Optimizing, above-mentioned Heat preservation crucible, the cross section of described ring cavity is square, and the length of side of the cross section of ring cavity is the 1/2.25 of the thickness of crucible body sidewall.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.In order to gather thermal source in classroom instruction experimentation as far as possible, reduce the loss of heat.Adding arc groove in the technical scheme of the application, the heat of alcohol burner is gathered by arc groove, prevents the heat of alcohol burner to scatter and disappear.Gather effect to improve the heat of arc groove, the radian of arc groove is set to 2. 27.In order to prevent the heat in crucible cavity to scatter and disappear, higher temperature is kept in making crucible cavity, improve firing rate, the design of the application arranges some ring cavities be arrangeding in parallel in the sidewall of crucible body, the partial heat gathered in making arc groove is along connecting tube and connects cavity rising, forms the distribution of uniform heat in the sidewall of crucible body.

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 Heat preservation crucible, and including crucible body, the sidewall of crucible body is cylindrical barrel, and the bottom of crucible body is provided with horizontal ends, and crucible body is internally provided with crucible cavity；Being provided with annular projection on described crucible cavity inner wall, annular projection is provided with upper cover plate, upper cover plate includes cover plate I and cover plate II, cover plate I and cover plate II pivot joint；Being provided with an arc groove on described horizontal ends lower surface, the radian of arc groove is 2.27；Being provided with some ring cavities be arrangeding in parallel in the sidewall of described crucible body, the spacing of ring cavity is the 1/10 of crucible height；Being provided with connection cavity between described two adjacent toroidal cavities, be provided with connecting tube between the ring cavity and arc groove of horizontal ends, connecting tube is cylindrical cavity, connects cavity and is perpendicular to arc groove.The cross section of described ring cavity is square, and the length of side of the cross section of ring cavity is the 1/2.25 of the thickness of crucible body sidewall.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.In order to gather thermal source in classroom instruction experimentation as far as possible, reduce the loss of heat.Adding arc groove in the technical scheme of the application, the heat of alcohol burner is gathered by arc groove, prevents the heat of alcohol burner to scatter and disappear.Gather effect to improve the heat of arc groove, the radian of arc groove is set to 2. 27.In order to prevent the heat in crucible cavity to scatter and disappear, higher temperature is kept in making crucible cavity, improve firing rate, the design of the application arranges some ring cavities be arrangeding in parallel in the sidewall of crucible body, the partial heat gathered in making arc groove is along connecting tube and connects cavity rising, forms the distribution of uniform heat in the sidewall of crucible body.
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.
