Rotary evaporator

Abstract

The invention relates to the field of evaporation drying equipment, and particularly relates to a rotary evaporator. The technical scheme adopted in the invention is as the follows that the rotary evaporator comprises a vacuum pump, a condensation pipe, a feeding pipe, a feeding valve, a rotary evaporation main machine, a floating ball liquid level meter, a liquid storage bottle, an evaporation bottle, a recovery bottle, a water bath, a controller and a support frame. The rotary evaporator is characterized in that the top of the support frame is provided with the controller; adjustable fixingclamps are arranged on the support frame; one fixing clamp at one side of the support frame is used to fix the condensation pipe and the rotary evaporation main machine; one fixing clamp at the otherside of the support frame is used to fix the recovery bottle; the upper end of the rotary evaporation main machine is connected with the condensation pipe; the lower end of the rotary evaporation mainmachine is connected with the evaporation bottle; a floater capable of adjusting the height of a duct plug is arranged in the evaporation bottle; the liquid storage bottle and the evaporation bottleare arranged in the same water bath; and the evaporation bottle consists of two hemispheres which are symmetric with each other from left to right, is sealed by a sealing ring, and is fixed by a fixing clamp sleeve. The rotary evaporator provided by the invention has the advantages that the evaporation bottle is vertically installed, so that the loss of the rotary evaporation main machine is reduced; automatic feeding can be realized; the distillate is easy to discharge; and continuous production can be carried out.

Description

technical field [0001] The invention relates to the field of evaporation and drying equipment, in particular to a rotary evaporator. Background technique [0002] Rotary evaporator is an extraction equipment that conducts vacuum distillation and concentration of materials under reduced pressure. It is mainly used in chemical, biological, food, pharmaceutical and other fields. The evaporating flask of the traditional rotary evaporator is generally installed obliquely, which will cause damage to the rotary evaporator when rotating, and even cause the evaporating flask to fall off and shorten the life of the rotary evaporator; the traditional evaporating flask adopts an integrated structure, but some special materials During concentrated extraction, the solvent in the material needs to be evaporated to a minimum or directly evaporated to dryness, and the residual material on the inner wall of the evaporating flask causes a decrease in yield; traditional evaporators need to manu...

The evaporating flask of the traditional rotary evaporator is generally installed obliquely, which will cause damage to the rotary evaporator when rotating, and even cause the evaporating flask to fall off and shorten the life of the rotary evaporator; the traditional evaporating flask adopts an integrated structure, but some special materials During concentrated extraction, the solvent in the material needs to be evaporated to a minimum or directly evaporated to dryness, and the residual material on the inner wall of the evaporating flask causes a decrease in yield; traditional evaporators need to manually add materials, which wastes labor and increases production costs. Therefore, further improvement is required
