Problems solved by technology
In the past, for materials with high viscosity, only the fixed scraper was selected, and it was impossible for the fixed scraper to be in contact with the inner surface of the main cylinder, and there was always a certain gap between them, which reduced the evaporation effect to a certain extent

The invention relates to a rotary film evaporator, in particular to a novel efficient evaporator which can carry out falling film evaporation in vacuum by a rotating scraper blade to form a film forcibly. The evaporator essentially adopts a jacket arranged in an evaporating cylinder in which a main shaft is installed. A plurality of rotor beams are arranged on the main shaft; the upper end and the lower end of the evaporating cylinder are respectively provided with an upper capped end and a lower capped end; a motor assembly is installed on the upper end of the evaporating cylinder. The evaporator is characterized in that: the rotor beams are connected with supporting boards which are connected with one end of elastic boards by fasteners; the other end of the elastic boards is connected with the scraper blade by fastening. The scraper blade is close to the inner wall surface of the evaporating cylinder. The evaporator has simple, compact and reasonable structure. An elastic scrapper blade device is used so that a rotary including board can be attached to the inner surface of the evaporating cylinder under the condition of high viscosity materials; owing to full and complete contact, the effect of heat transfer can be enhanced and the evaporation process can be efficiently and reliably completed at high speed.
Description
technical field [0001] The invention relates to a rotary thin film evaporator, in particular to a novel high-efficiency evaporator capable of forming a film forcibly through a rotating scraper and performing falling film evaporation under vacuum conditions. Background technique [0002] Rotary thin film evaporator is mainly involved in the concentration, evaporation, rectification and desolventization of materials in petrochemical, pharmaceutical and food processing industries; it has a large heat transfer coefficient, high evaporation intensity, short flow time, and large operating flexibility. It is widely used in petrochemical, pharmaceutical, pesticide, daily chemical, food, fine chemical and other industries. In the prior art, the rotary thin film evaporator mainly includes a main shaft, a rotating bracket device driven by the main shaft, a jacket, a cylinder, upper and lower heads and a motor. In the rotary thin film evaporator, the scraper device is a key device of t...
