Abstract

The invention relates to a single cone vacuum drier, which belongs to the technical field of heat exchange. The single cone vacuum drier is used for vacuum drying thermally sensitive medicines and organic solvent chemical products and recovering the organic solvent and comprises an inner cylinder body, a steam heating jacket, a left rotating shaft, a right rotating shaft, a left bearing block, a right bearing block, an inner heating plate, a driving chain wheel, a driver and the like, wherein one end of the inner cylinder body adopts a standard elliptical end socket; the other end of the inner cylinder body adopts a conical body; for efficiency of a product in drying and the increase of the number of inner heating plates, the standard elliptical end sockets are respectively arranged at two ends of the steam heating jacket; the system is heated by using 40-100 low-temperature saturated water steam instead of traditional hot water; the inner heating plates are arranged, so that the total heating area of the drier is increased by 2-4 times compared with that of a traditional dual cone vacuum dryer; the thickness of stainless steel of each inner heating plate is only 1 / 4-1 / 2 of the thickness of the cone; and one single cone vacuum drier can be equivalent to a traditional dual cone vacuum dryer, thus the drying efficiency can be multiply improved and the consumption of the stainless steel and power consumption can be greatly saved.

Description

technical field [0001] The invention relates to a single-cone vacuum dryer, which belongs to the technical field of heat exchange, and is suitable for vacuum drying and recovering organic solvents of medical and chemical products with heat sensitivity and containing organic solvents. Background technique [0002] The main disadvantages in the structure of the traditional double-cone vacuum dryer are: the large-scale heat exchange area cannot be achieved when it is large-scaled, and the volume expansion ratio of the dryer is much larger than the heat exchange area, which seriously affects the large-scale drying. production; although the double-cone structure is conducive to cleanly unloading the dry product, it affects the volume of the dryer; now the traditional double-cone is heated by hot water with a temperature difference between the inlet and outlet, and its heat transfer coefficient is small and increases The burden and investment of a hot water installation.
