Novel rotary evaporator

Abstract

The invention discloses a novel rotary evaporator. The novel rotary evaporator comprises a base, wherein the base is internally provided with a vibration absorption cushion; the vibration absorption cushion is internally provided with vibration absorption springs; a distillation chamber is arranged at the upper side of the base; a water-bath pot is arranged in the distillation chamber; heater is arranged at the bottom of the water-bath pot; a distillation flask is arranged at the upper end of the water-bath pot; hydraulic cylinders are arranged at left and right ends of the upper side of the distillation chamber; a motor chamber is arranged at the upper sides of the hydraulic cylinders; a fixed sleeve is arranged at a connecting part of the motor chamber and the distillation flask; a first motor is arranged at the right end in the motor chamber and a driving gear is arranged at the upper end of the first motor; a driven gear is arranged at the upper end of the distillation flask; a second motor is arranged at the upper side of the motor chamber; a stirring shaft is arranged at the lower side of the second motor; stirring blades are arranged at the lower end of the stirring shaft; an exhausting pipe is arranged at the lower side of the fixed sleeve; an air pump is arranged on the exhausting pipe. By arranging a hoisting device, a rotating device, a stirring device and a vibration absorption device, objects needing to be distilled can be effectively distilled, so that the distillation efficiency is improved and the surrounding environment is protected.

Description

technical field [0001] The invention relates to a distillation device, in particular to a novel rotary evaporator. Background technique [0002] Rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in pharmaceutical, chemical and biopharmaceutical industries. The principle is to heat at a constant temperature under vacuum conditions to make the rotary bottle rotate at a constant speed, and the material forms a large-area film on the bottle wall and evaporates efficiently. The solvent vapor is cooled by a high-efficiency glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency. It is especially suitable for the concentration and purification of biological products that are easy to decompose and denature at high temperature. Because the existing rotary evaporator cannot well control the distance relationship between the rotary bottle and the water bath, the evaporation ...
