The invention relates to the technical field of chemical equipment, in particular to a glass lining film evaporator. The glass lining film evaporator is used for solving the technical problem of fastabrasion of scraper assemblies in glass lining film evaporators in the prior art. The glass lining film evaporator comprises a separation cylinder, an evaporation cylinder and a lower cylinder body which are sequentially arranged from top to bottom, wherein a sieve plate is arranged between the evaporation cylinder and the lower cylinder body; since the end part of a rotating shaft is connected with the sieve plate, the rotating shaft can be prevented from swinging sharply, so that the ineffective abrasion of a scraper assembly is reduced, and the service life of the film evaporator is prolonged. In addition, the sieve plate can also play a role in filtering evaporated materials.
