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 [0001] The invention relates to a double-layer heat-insulating crucible, which belongs to the field of teaching equipment. Background technique [0002] The crucible is an important part of a chemical instrument. It is a container for melting and refining metal liquids and solid-liquid heating and reaction, and is the basis for ensuring the smooth progress of chemical reactions. There are many models and specifications of the crucible, and the application is not limited by the production scale, batch size and the variety of smelted substances. It can be selected arbitrarily, has strong applicability, and can guarantee the purity of the smelted substance. In classroom teaching experiments, after using the crucible for experiments, sometimes it is necessary to pick up the crucible and show it to the students, but the temperature of the crucible is very high after heating, so it is inconvenient to pick it up and show it. Contents of the invention [0003] In ...
