Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a devolatilizer heating device. Background Art

[0002] The principle of the devolatilizer is to use centrifugal force and airflow force to separate grains and impurities. The main components of the devolatilizer include screens, fans, vibrating screens, conveyor belts, etc. When the grains enter the devolatilizer through the conveyor belt, they are first screened by the vibrating screen to screen out large particles of impurities and straw. Then, the grains enter the fan, and the airflow generated by the fan blows away the light impurities, while the heavy grains are sucked into the screen. Under the action of the screen, the grains are separated, and the impurities and straw are discharged from the machine. The principle of the devolatilizer is to use centrifugal force and airflow force for separation. The grains and impurities are separated by screens, fans, vibrating screens, conveyor belts and other components. The devolatilizer usually uses a heating device, and the heating effect of the existing devolatilizer heating device is poor. Summary of the invention
