Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnesium carbonate experiments, in particular to a drying cabinet for magnesium carbonate experiments. Background Art
[0002] Magnesium carbonate is an inorganic compound with the chemical formula MgCO3, molecular weight 84.31, relative density 3.037, and appearance as white granular powder. It decomposes at 350°C and loses carbon dioxide at 700°C. It is slightly soluble in cold water and slowly soluble in acid. Its trihydrate is colorless needle-shaped crystals with a melting point of 165°C and a relative density of 1.850. Its pentahydrate is white monoclinic crystals with a relative density of 1.73. It decomposes when heated in air.
[0003] The amount of magnesium carbonate used in the laboratory is relatively small. After searching, it was found that the publication number is CN108101388B, and the name is a magnesium carbonate drying and calcining processing center. The application proposes a magnesium carbonate drying and calcining equipment, which can fully calcine and dry the magnesium carbonate. However, due to its complex system and huge size, it is not suitable for laboratory use. The traditional laboratory magnesium carbonate drying equipment is a drying box. When using the traditional drying box, the magnesium carbonate needs to be spread flat on the drying tray and placed statically inside the drying box to be dried by heat. Since the magnesium carbonate is in a static state at this time, the magnesium carbonate on the surface is dried first, and the drying speed of the magnesium carbonate located below is lower than that of the magnesium carbonate on the surface, resulting in uneven drying of the magnesium carbonate and low drying efficiency. At the same time, after drying, the staff needs to collect the magnesium carbonate, which is also troublesome and can be further improved.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
