Rotary polymer distiller

Abstract

The invention belongs to the field of molecular distillation equipment, and particularly relates to a rotary macromolecular distiller which comprises a distillation cylinder, a motor is mounted at thetop of the distillation cylinder, the output end of the motor is connected with a rotating rod rotationally connected to the interior of the distillation cylinder, and a transmission device is arranged on the outer side of the rotating rod. The transmission device comprises a horizontally-arranged rotating plate, the middle of the rotating plate is movably connected to the outer portion of the rotating rod in a sleeving mode through a first one-way bearing, cylindrical holes are formed in the periphery of the rotating plate, and movable rods are arranged in the cylindrical holes. The belts ina film scraping device are arranged at equal intervals along the center of the distillation cylinder, a uniform thin film is formed when the belts rotate, and when redundant liquid which is not subjected to film forming splashes towards the middle, the liquid is continuously brought to the other side of the inner wall of the distillation cylinder by the non-film-scraping ends of the belts to be subjected to the film forming process; and a plurality of belts form a redundant liquid to continuously participate in the film forming operation, so that the unseparated liquid is prevented from splashing onto the condensation plate.

Description

Technical field[0001]The invention relates to the field of molecular distillation equipment, and in particular to a rotary polymer distiller.Background technique[0002]The molecular distillation equipment passes through a gentle process. The feed liquid mixture flows through a heated cylindrical vacuum chamber. The liquid is scraped into a thin film and adheres to the vacuum chamber wall. The light substances in the liquid mixture are heated and evaporated and leave from the hot surface. And is captured by the cold surface, and the heavy components of the liquid mixture leave the hot surface, so that the liquid mixture is separated.[0003]There are many kinds of molecular distiller at present, the most commonly used is the scraper molecular distiller, the scraper is attached to the inner wall, and the mechanical deformation, thermal expansion deformation, thermal stress deformation, centrifugal force, mechanical vibration and other factors will cause the outer edge of the scraper It i...

AI Technical Summary

Problems solved by technology

However, when the scraper rolls, the centrifugal force generated will cause part of the excess liquid that has not formed a film to fly to the axis of the barrel and be captured by the cold surface, so that the unseparated liquid and light molecules are remixed, and the separation effect is not achieved, and the separation efficiency
