Description

Technical Field

[0001] The utility model relates to the technical field of muffle furnaces, in particular to a multi-station muffle furnace heating device. Background Art

[0002] Muffle furnace is a kind of laboratory equipment used to heat samples or materials at high temperatures while isolating them from the external environment. It usually consists of a heating furnace and a sealed isolation chamber. It is often used in laboratories to pyrolyze and calcine substances. By heating samples at high temperatures, the substances are decomposed, developed, and burned to obtain the desired products. Muffle furnaces can provide a high temperature environment and maintain high stability, which can reach more than 1000°C. This high temperature stability makes muffle furnaces widely used in high temperature experiments and production. The working principle of the muffle furnace is to generate high temperature in the heating furnace and isolate the sample from the outside world through the isolation chamber to ensure that the experiments or treatments carried out under high temperature conditions are not affected by the outside world.

[0003] At present, the traditional muffle furnace is designed with only one movable door, which is used to open and close to achieve the sealing of the heating furnace and facilitate the removal of samples. When the movable door is opened, the temperature inside the furnace will produce a large heat exchange with the outside world. Frequent opening and closing will cause a certain temperature fluctuation effect on the temperature inside the furnace, which is not conducive to maintaining the constant temperature heating conditions of the samples in the furnace. At the same time, when placing and removing samples, the heat in the furnace will diffuse outward, and the operators are at risk of high temperature burns when placing and removing samples.
