Abstract

The invention relates to the technical field of evaporation equipment, in particular to an intelligent water saving type rotary evaporation concentration device. The intelligent water saving type rotary evaporation concentration device is based on the structure of the existing rotary evaporator, a cylindrical distillation drum made of corrosion-resistant metal is used for replacing an original distilling flask, a rotary shaft originally forming an included angle of 30-45 degrees with the horizontal plane is changed into a horizontal rotary shaft, an evaporative gaseous substance condensed intoa liquid state by the original condensing system is compressed by a steam compressor, a to-be-distilled sample is continuously heated by use of temperature difference between a compressed fraction and a to-be-distilled liquid through heat exchange by the aid of the distillation drum wall, an electric heating assembly is used at a feeding pipe to realize preheating during distillation starting, and a condensing assembly, refrigerants, water bath (oil) pots and a lifting system assembly are omitted. The intelligent water saving type rotary evaporation concentration device is water-saving and energy-saving, can control distillation by a control panel or a computer and is applicable to water lacking environments, microgravity environments and environments with higher requirements for water saving and maintenance.

Description

technical field [0001] The invention relates to the technical field of evaporation equipment, in particular to an intelligent water-saving rotary evaporation concentration device. Background technique [0002] Rotary evaporator is an extraction experimental equipment for vacuum distillation and concentration of materials. It is widely used in experiments such as large-scale concentration, drying, extraction and recovery of samples, especially for rapid distillation of large amounts of solvents. Existing rotary evaporators are usually composed of vacuum pumping devices, heating devices, condensing devices, rotating devices and other components. The principle of rotary evaporators is mainly controlled by electronic equipment, so that the flask rotates at a constant speed at the most suitable speed to form a thin film of solvent , increase the evaporation area, and use a vacuum pump to make the evaporation flask in a negative pressure state. The evaporation flask is placed in a...
