Centrifugal scraper film evaporator

The invention discloses a centrifugal scraper film evaporator which comprises a bottom plate used for bearing the whole device, a heating bin used for heating, an evaporation bin used for carrying out evaporation and concentration and a base solution disc used for collecting a concentrated solution, wherein the heating bin is arranged above the bottom plate, the evaporation bin is arranged in the heating bin, the base solution disc is arranged below the evaporation bin, and a cleaning plate is arranged in the evaporation bin. According to the invention, the structure is simple, the use is convenient, the cleaning plate and the base solution disc capable of moving up and down are arranged, after the stock solution evaporation concentration is completed, the lifting column is started to drive the base solution disc to move downward so as to drive the cleaning plate to move downward, the cleaning plate can clean the base solution attached to the inner wall of the evaporation bin, the base solution is scraped downwards to fall into the base solution disc to be collected, and the problems that waste is caused due to the fact that the base solution attached to the interior of the evaporation bin is not collected thoroughly when an existing evaporator waits for the stock solution to fall into the base solution disc slowly and downwards are solved, and the base solution collecting efficiency is very low are solved.
