Description

一种电机不易损坏的回转式清污机 技术领域
本发明涉及清污机领域，尤其涉及一种电机不易损坏的回转式清污机。
 背景技术
回转格栅清污机是一种可以连续自动拦截并清除流体中各种形状杂物的水处理专用设备，可广泛地应用于城市污水处理、自来水行业、电厂进水口，回转耙式格栅清污机在运行时，耙齿把节流在格栅面上的杂物自下而上带至出渣口，当耙齿回转时，杂物依靠重力自行脱落，从卸料口内落入输送机内排出。
 技术问题
现有回转式清污机在打捞时，遇到一些重物或者杂物卡住耙齿时，会造成清污机电机过载或者耙齿、格栅损坏。
 技术解决方案
本发明的目的是提供一种电机不易损坏的回转式清污机。
本发明的创新点在于电机输出轴和主动链轮之间增加剪切连接，当电机过载时，剪切销无法承受电机的输出扭矩，剪切销断裂，主动链轮不再转动，回转式清污机停止运行。
为实现上述发明目的，本发明的技术方案是：一种电机不易损坏的回转式清污机，包括机架，所述机架顶面设有主格栅，所述主格栅包括若干沿机架长度方向布置的竖向主格栅条，所述竖向主格栅条底面通过若干横向主格栅条连接，所述机架两侧设有环形轨道，所述环形轨道内设有环形链条，所述环形链条包括多节链节和多个滚轮，相连两个链节之间通过销轴连接，所述销轴上套设有滚轮，所述环形轨道顶部开口，开口处设有主动轴，主动轴两端通过轴承和机架连接，所述主动轴上设有两齿轮，所述环形链条套在齿轮上，所述环形链条上设有若干水平布置的打捞轴，打捞轴两端分别连接在两环形链条上，所述打捞轴上设有两排打捞齿，所述两排打捞齿在机架顶面处形成角度小于150°的且朝上的夹角，所述主动轴一端设有带动主动轴转动的驱动组件，所述驱动组件包括位于主动轴上的从动链轮、位于机架上的电机，所述电机的输出轴上设有主动链轮，所述从动链轮和主动链轮通过传送链连接，所述电机的输出轴和主动链轮之间通过连接套连接，所述连接套包括圆套和位于圆套一端的法兰盘，所述圆套和电机的输出轴连接，圆套和电机的输出轴径向固定，所述主动链轮和法兰盘通过剪切销连接。电机输出轴和主动链轮之间增加剪切连接，当电机过载时，剪切销无法承受电机的输出扭矩，剪切销断裂，主动链轮不再转动。
进一步地，机架顶部主动轴的两端设有滑槽，所述滑槽内设有滑动块，所述主动轴两端通过轴承和滑动块连接，所述滑动块上连接有和滑槽平行布置的丝杆，所述滑槽的顶部设有用于穿过丝杆的通孔，丝杆穿过通孔且通孔两侧设有旋接在丝杆上的螺母。通过丝杠拉动滑块从而带动齿轮沿着滑槽方向移动，可以调节环形链条张紧程度。
进一步地，滚轮为尼龙材质。尼龙材质更为耐磨，不易损坏。
进一步地，机架顶部设有和主格栅衔接的弧形转板。弧形转板可以使得打捞轴的两排打捞齿打捞到的杂质在翻转时不掉到主轴处。
进一步地，夹角的角度为120°。
 有益效果
本发明中电机输出轴和主动链轮之间增加剪切连接，当电机过载时，剪切销无法承受电机的输出扭矩，剪切销断裂，主动链轮不再转动，回转式清污机停止运行。
