Novel rotary evaporator

Abstract

The invention discloses a novel rotary evaporator. The novel rotary evaporator comprises a base, a water bath kettle is arranged on the upper side of a base plate, an electric control box is arrangedon the right side of the water bath kettle, an L-shaped connecting plate is arranged at the outer end of the upper side of the base, a screw rod is connected with the L-shaped connecting plate, a first motor is arranged outside the screw rod, a sliding block is arranged on the screw rod, an L-shaped connecting rod is arranged on the inner side of the sliding block, a third motor is arranged on theupper side of the L-shaped connecting rod, an upper side of the L-shaped connecting rod is provided with a bearing seat, connecting pipes are arranged inside the bearing seat, a rotary evaporation bottle is arranged between the connecting pipes, a feeding port is arranged on the right side of the upper side of the rotary evaporation bottle, a stirring rod shaft is arranged inside the rotary evaporation bottle, a second motor is arranged on the right side of the stirring shaft, stirring rods are arranged on the upper and lower sides of the stirring shaft, and a connecting hose is arranged on the left side of the connecting pipe on the left end, and a first condensing tube, a second condensing tube, and a liquid storage tube are arranged on the left side of the connecting hose. The novel rotary evaporator can effectively facilitate stirring and moving up and down in a process of rotary evaporation of the evaporator, and can effectively facilitate rotary evaporation of the evaporator.

Description

technical field [0001] The invention relates to the field of evaporation, in particular to a novel rotary evaporation equipment. Background technique [0002] Rotary evaporators are already known in various embodiments. Such rotary evaporators are used to economically separate liquid mixtures and solutions by taking advantage of the different boiling points of the components, so that rotary evaporators can also be used for drying, solvent recovery and similar processes. Usually a thermal bath is used as the evaporator element, in which the heated water or oil volume is located. Rotating in a heated volume of water or oil in a thermal bath, the evaporator flask contains the solution to be evaporated inside its flask. The solution is distributed as a thin liquid film on the heated inner wall of the rotary evaporator flask, where it can be easily vaporized. The mixing caused by the addition of the heating bath makes it significantly easier to adjust the effective heating tem...
