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

一种耐磨损的搅拌叶轮
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。
