The utility model relates to the technical field of
evaporation equipment, in particular to a centrifugal scraper film
evaporator capable of removing free amine of an
epoxy curing agent, which comprises an
evaporation barrel, a driving component, a rotating shaft, a liquid bead baffle, a dispersion disc and a scraper, an inner cavity of the
evaporation cylinder is provided with a steam cavity, a dispersion cavity and an evaporation cavity which are sequentially communicated from top to bottom; the liquid bead baffle, the dispersion disc and the scraper are arranged on the rotating shaft from top to bottom at intervals, the liquid bead baffle is located in the steam cavity, the dispersion disc is located in the dispersion cavity, the scraper
assembly is located in the evaporation cavity, and the scraper is connected with the rotating shaft through a connecting
assembly. The connecting seat is fixedly connected with the scraper, the connecting seat is slidably connected with the mounting seat, one end of the elastic element abuts against the connecting seat, the other end of the elastic element abuts against the mounting seat, a uniform and controllable liquid film is formed through combination of
centrifugal force film forming and the elastic scraper, the gas-liquid exchange area is increased, and the evaporation efficiency is improved.
