Rotary evaporator capable of automatically controlling continuous feeding and discharging

Abstract

The invention relates to the technical field of evaporation equipment, in particular to a rotary evaporator, and particularly relates to a rotary evaporator capable of automatically controlling feeding and discharging and cleaning process. According to the rotary evaporator capable of automatically feeding and discharging, creative improvement is conducted based on the structure of existing rotaryevaporators, a feeding channel, a discharge channel, a cleaning channel, a liquid unloading channel and a fraction discharging channel are added on common use channels for introducing atmosphere andfeeding, each channel is controlled by pumps, switches, computers or touch screens, different working modes are set, automatic feeding and discharging, automatic cleaning and waste liquid dischargingand automatic fraction discharging are achieved during the use of the rotary evaporator, frequent manual operation during the use of the rotary evaporator is avoided, the workload is effectively reduced, which enables the rotary evaporator to be operated automatically, continuously and efficiently during distillation process, a lifting system is not needed, and the workload and operating costs ofoperation and maintenance are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of evaporation equipment, in particular to a rotary evaporator, in particular to a rotary evaporator capable of automatic feeding and discharging. 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.

Problems solved by technology

[0005] The invention provides a rotary evaporator with multiple modes to choose from, intelligent electronic equipment such as a computer or a touch screen, which can automatically control the feeding and discharging, cleaning and fractionation, and can automatically and continuously repeat a complete set of operating steps in a certain mode. There are problems in the technology that the rotary evaporator has a low degree of automation and cannot continuously feed and discharge materials, clean and discharge fractions, that is, to realize the intelligence of the rotary evaporator, and solve the problem that the rotary evaporation process cannot be separated from the experimenter
