Description

一种叶轮式增氧机叶轮
本实用新型涉及一种用于水产养殖和污水处理的增氧机装置，具体是涉及叶轮式增氧机的叶轮。主要应用于水产养殖和污水处理。
现有技术的叶轮式增氧机塑料叶轮，一般包括叶片，轮锥体和连接盘。一种是采用叶片与轮锥体活动连接的；一种是采用连接盘与轮锥体活动连接的；一种是采用片状轮锥体与叶片相连制成片件组装成型的；另一种是一体注塑成型。因此都是只注重工艺和生产成本的需求，没有总体兼顾到叶轮实际使用中既有叶片折断的情况需单独更换，也有因连接盘与轮锥体连接筋板放置不合理导致叶轮变形，叶轮安装困难等情况。
本实用新型的目的在于提供一种使用效率高，寿命长，可更换叶片，负荷低，综合性能优异的叶轮式增氧机叶轮。
本实用新型叶轮的技术设计方案是：主要是配套在叶轮式增氧机上的叶轮，叶片单独注塑成形并可拆卸，上轮锥体、连接盘和加强筋一体注塑成型。
本实用新型的一种叶轮，其叶片与轮锥体用螺栓连接，叶片有凸块插入轮锥体的坑槽内定位。
本实用新型的一种叶轮，轮锥体分上下轮锥体。
本实用新型的一种叶轮，上轮锥体与连接盘的连接筋板上有透气孔，此孔兼可用作安装叶轮拧螺栓的操作位置孔。
本实用新型的一种叶轮，上下轮锥体及叶片上均开有一排透气小孔。
本实用新型的一种叶轮，下轮锥体开有大透气孔，大透气孔上连有塑料网。
本实用新型的一种叶轮，轮锥体与连接盘有4条加强筋相连，而且加强筋不对正叶轮中心，是按顺时针螺旋方向，可减轻水体阻力。
本实用新型公开了一种叶轮，主要是涉及叶轮式增氧机叶轮，对叶轮的叶片，轮锥体，连接盘和加强筋均按实际应用而设计。因此，与现有技术相比，具有使用效率高，可更换叶片，寿命长，负荷低，综合性能优异的优点。
以下结合附图作进一步说明。
图一是本实用新型所述叶轮的主视图示意图；
图二是本实用新型所述叶轮的俯视图示意图；
图三是本实用新型所述叶轮的轮锥体与叶片螺栓连接的截面示意图；
图四是本实用新型所述叶轮的叶片插入轮锥体定位的截面示意图；
本实用新型主要是涉及叶轮式增氧机叶轮，其整体结构如图一、图二所示，由连接盘1，上轮锥体2，叶片3，下轮锥体4，加强筋5和加强筋7所构成，叶片与轮锥体用螺栓6相连，叶片3可拆卸，连接盘1、上轮锥体2、加强筋5和加强筋7均一体注塑成型，下轮锥体中心开有大透气圆孔并用塑料网遮盖，上轮锥体与连接盘连接筋板上开有4个透气孔，轮锥体与连接盘有4条加强筋7相连，而叶片与轮锥体按如图三截面形状成倾斜夹角α连接，轮锥体及叶片上按如图四截面形状均开有一排透气小孔8。
