A heating structure for a recycled material drying drum

Abstract

This utility model relates to the technical field of recycled material drying equipment, specifically to a heating structure for a recycled material drying cylinder, including a cylinder body and a combustion chamber. Inside the cylinder body, along the material conveying direction, a guiding section, a combing section, and a heating section are arranged sequentially. A cavity cleaning module is provided on the side wall of the heating section. The cavity cleaning module includes a cleaning chain, with mounting plates at both ends of the cleaning chain. The mounting plates are equipped with adjustment devices for adjusting the tension of the cleaning chain. The design of the cleaning chain enables secondary material dispersal during cylinder rotation. Simultaneously, the cleaning chain achieves rapid heat conduction and cleaning of the inner wall, improving material heating efficiency while ensuring the cleanliness of the cylinder sidewalls, reducing subsequent equipment maintenance and cleaning costs. Furthermore, the adjustment device allows for adjusting the tension of the cleaning chain according to the material specifications, enhancing the equipment's applicability.
