Description

Technical Field

[0001] The utility model belongs to the technical field of evaporation, in particular to a high-efficiency evaporation tank. Background Art

[0002] During the production of epoxy resin or the recovery of waste liquid, an evaporator is required to evaporate the liquid material to evaporate the water or organic solvent therein. The following problems exist during the use of the current evaporator.

The propeller 503 stirs the liquid to move upward from the center, making the liquid temperature more uniform and convenient for evaporation operation, and the scraper 502 scrapes the inner wall of the tank body 1 to prevent the material from scraping the wall and affecting the heat exchange efficiency.

[0061] The driving assembly 4 includes a motor and a reducer. The housing of the motor is fixedly connected to the housing of the reducer. The housing of the reducer is fixedly connected to the upper cover 2. The output shaft of the motor is connected to the input end of the reducer.
