[0002] The paddle-type sludge dryer is a hollow shaft with spiral hollow blades, through which heat carriers pass. The material to be dried is dried by sufficient heat exchange during stirring and is continuously transported forward by the action of the spiral hollow blades. To achieve drying of the material, the wet material must be in full contact with the spiral hollow blades. Since the wet material is continuously transported forward by the action of the spiral hollow blades, in order to make the wet material in full contact with the spiral hollow blades, the hollow shaft will be designed to be longer, which makes the existing dryer longer as a whole, occupies a larger space, and is limited in use, and is only used in large places.

[0003] After the existing blade dryer is used, it is troublesome to clean the wet material on the surface of the hollow blade. Manual cleaning is time-consuming and the cleaning effect is general. If the wet material on the surface of the hollow blade is not effectively removed, the heat exchange efficiency of the hollow blade will be reduced during the next drying work, affecting the normal progress of subsequent drying work.

[0004] Therefore, in order to solve the above problems, a scraping device with hollow blades is proposed. Utility Model Content
