Abstract

本发明提供了一种耐磨损搅拌叶轮，它采用在叶 轮表面静电喷涂导电环氧树脂后再喷涂聚四氟乙烯 的途径，来达到使搅拌叶轮具有耐磨损，延长使用寿 命的目的。

Description

本发明涉及一种耐磨损的搅拌器叶轮。
在工业生产过程中，对粉尘的处理方法通常是采取将粉尘排入污水池中，再通过搅拌机叶轮的旋转，使粉尘颗粒悬浮起来，由排水泵将其和水一起排到规定的场所进行处理。搅拌机叶轮一般为铸铁或钢质，由于受到粉尘颗粒的摩擦，极易受到磨损。在现有技术中，为达到防止磨损，延长叶轮的使用寿命，采用在叶轮的表层热喷涂或喷焊一层合金粉末，使之硬度增加，可达到HRc50～60（如上海冶炼厂出版的《氧乙炔焰喷涂涂喷焊合金粉末》），其不足之处是价格昂贵，处理工艺复杂。目前还有采用在叶轮表层粘贴陶瓷的方法来降低成本，达到耐磨损的目的，但其缺点是刚度较差，在碰到较硬的物质（如焊条头等）时易被击碎。
本发明的目的是用一种价格便宜，工艺简单的物质替代合金粉末或陶瓷，喷涂在叶轮表面以达到使叶轮耐磨损、延长使用寿命的目的。
为达到上述目的，本发明利用聚四氟乙烯的纸摩擦系数，较好的化学稳定性和耐腐蚀性等，将其作为喷涂材料喷涂在叶轮表面，由于聚四氟乙烯不易直接喷涂在金属叶轮的表面，故采用导电环氧树脂作为中间介质，先用静电将导电环氧树脂喷涂在叶轮表面，再复盖一层聚四氟乙烯。形成具有一层均匀聚四氟乙烯涂层的叶轮。从而使叶轮达到耐磨损和延长使用寿命。它具有价格便宜，工艺简单，耐磨损能力较强，应用范围广（可推广运用在各种推进器叶轮上）等特点。
