TECHNICAL FIELD

[0001] The utility model relates to blade technical field, concretely is a kind of self-cleaning dryer blade. BACKGROUND

[0002] Dryer blade is one of the core components in dryer equipment, mainly used for stirring, crushing and mixing material during drying process to accelerate water evaporation and improve drying efficiency. Dryer is widely used in chemical industry, pharmaceutical industry, environmental protection, food industry, agriculture and other industries, especially in sludge treatment, biomass drying, chemical product drying and other fields. Stirring and mixing: the main function of dryer blade is to stir and mix wet material, so that it is evenly heated during drying process, avoiding local overheating or uneven drying. Through continuous stirring of blade, material can form flow state in dryer, promoting heat transfer and accelerating drying speed. Crushing material: for some materials containing large or caked pieces, dryer blade is usually designed with crushing function, which can crush large pieces into smaller particles, thereby increasing the surface area of material and further improving drying efficiency. Promote heat transfer and mass transfer: during stirring, blade can bring material into contact with heat source (such as steam, hot air, etc.), promoting heat transfer and water evaporation. At the same time, the design of blade usually considers the flowability of material and heat transfer efficiency to ensure efficient drying process. The structural design of dryer blade directly affects the performance and efficiency of dryer. According to different application scenarios and material characteristics, the design of blade will be different.

[0003] Currently, during drying process, some materials (such as sludge, biomass, chemical raw materials, etc.) are prone to form attachments or caked pieces on the surface of blade. These attachments not only increase the load of blade and reduce stirring efficiency, but also cause uneven material flow, thereby affecting drying effect. Self-cleaning function can automatically remove material attached to blade through high-speed rotation or special design of blade, avoiding the formation of caked pieces. Therefore, it does not meet the existing needs, and we propose a self-cleaning dryer blade. UTILITY MODEL CONTENTS
