Organic solvent recovery and purification device

The invention relates to a purification device, in particular to an organic solvent recovery and purification device. The invention relates to an organic solvent recovery and purification device which can drain and store backflow liquid so as to prevent the backflow liquid from being discharged again for distillation and improve the purification efficiency. An organic solvent recycling and purifying device comprises a heating cylinder, supporting rods, a heating plate and the like, the heating plate is fixedly connected to the lower portion of the outer side of the heating cylinder, and the four supporting rods are fixedly connected to the upper portion of the outer side of the heating cylinder in the circumferential direction at equal intervals. A heating plate is started to heat a heating cylinder, the heating cylinder heats and distills an organic solvent, steam generated in the heating process is discharged into a condensation pipe to be cooled and converted into liquid, a servo motor is started to rotate
