煤炭输送带表面对煤粉的仿生脱附研究

Bionic Anti-adhesive Study Between the Coal Conveyor Belt Surface and the Coal

分析了煤炭带式输送机输送带表面与煤粉粘附现象,从生物体表自洁现象中得到启示,利用生物仿生学原理,提出改善输送带表面形貌以达到与煤粉脱附的目的。以荷叶表面结构形貌为原型,分析其微观结构形貌,运用相似工程学原理设计出一种具有凸包结构的输送带表面形貌,以达到有效脱附煤粉,并建立该结构的实体模型。

With analysis of the phenomenon that coal fines adsorb to the belt surface on coal conveyor,a new idea focused on improvement in the surface topography of conveyor belt to decrease adhesion of coal fines is presented on the basis of inspiration from the biological self-cleaning phenomenon and perspective of bionics.The surface topography with papillary structure of conveyor belt surface is designed on the basis of Lotus-leaf-likes surface with analysis of its microstructure in accordance with similarity principle.The new structure could effectively prevent coal fines from adhering to conveyor belt surface.A model of the new structure is also built.
