Abstract
The invention discloses an annular heating crucible. The annular heating crucible comprises a crucible body, wherein the side wall of the crucible body takes the shape of a cylindrical tube, a horizontal end is arranged at the lower part of the crucible body, and a crucible cavity is formed in the crucible body; an arc-shaped groove with the radian of 2.65 is formed in the lower surface of the horizontal end; a heating channel which is cylindrical and helical is arranged in the side wall of the crucible body; the screw pitch of the cylindrical screw of the heating channel is 1/8 of the height of the side wall of the crucible body; the helical angle of the cylindrical screw of the heating channel is 26.5 degrees, and the end part of the heating channel is connected with the arc-shaped groove. The annular heating crucible has the advantages that the shortcomings in the prior art are overcome, and the structural design is reasonable and novel.
Description
Technical field
The present invention relates to a kind of annular-heating 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 annular-heating 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 annular-heating 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 an arc groove on described horizontal ends lower surface, the radian of arc groove is 2.65；It is provided with in the sidewall of described crucible body and adds the passage of heat, adding the passage of heat is cylindrical helical, the pitch of the cylindrical screw adding the passage of heat is the 1/8 of crucible body sidewall height, and the helical angle of the cylindrical screw adding the passage of heat is 26.5 degree, and the end adding the passage of heat connects arc groove；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.
Optimizing, above-mentioned annular-heating crucible, described crucible external body is enclosed with asbestos layer of cloth.
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 2.65.In order to prevent the heat in crucible cavity to scatter and disappear, higher temperature is kept in making crucible cavity, improve firing rate, what the design of the application arranged cylindrical helical in the sidewall of crucible body adds the passage of heat, the partial heat gathered in making arc groove rises along heating channel spiral shape, 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 annular-heating 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 an arc groove on described horizontal ends lower surface, the radian of arc groove is 2.65；It is provided with in the sidewall of described crucible body and adds the passage of heat, adding the passage of heat is cylindrical helical, the pitch of the cylindrical screw adding the passage of heat is the 1/8 of crucible body sidewall height, and the helical angle of the cylindrical screw adding the passage of heat is 26.5 degree, and the end adding the passage of heat connects arc groove；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.Described crucible external body is enclosed with asbestos layer of cloth.
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 2.65.In order to prevent the heat in crucible cavity to scatter and disappear, higher temperature is kept in making crucible cavity, improve firing rate, what the design of the application arranged cylindrical helical in the sidewall of crucible body adds the passage of heat, the partial heat gathered in making arc groove rises along heating channel spiral shape, 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.
