一种磨煤机用轴向分离器
本技术涉及磨煤机分离器
,特别是一种磨煤机用轴向分离器。
技术介绍
由于煤炭市场的变化,锅炉燃用煤种多变,根据煤种的不同,需要频繁调整调节挡板,而现有的磨煤机轴向分离器中,分离器内的调节挡板多采用人工调节,调节精度差、调节不同步。目前虽然公开了动静叶结合分离器等轴向分离器,但这些设备的结构较为复杂,制造成本高。
技术实现思路
本技术的专利技术目的是提供一种磨煤机用轴向分离器,该磨煤机用轴向分离器通过连杆将多块调节挡板连接,再通过驱动装置带动连杆转动,进而带动多块调节挡板同时转动,使多块调节挡板可实现同步调节控制。为达到上述目的,本技术所采用的技术方案是:一种磨煤机用轴向分离器,包括外壳体,所述外壳体的上端设有与所述外壳体相连通的出粉管,所述外壳体的下端设有与所述外壳体相连通的进粉管和回粉管,所述外壳体的内腔中固设有内筒体,还包括多块轴向设置的调节挡板及用于驱动所述调节挡板的驱动装置,多块所述调节挡板绕设于所述外壳体与所述内筒体之间的环形腔体内,多块所述调节挡板通过一连杆连接,所述驱动装置设于所述外壳体的上端;所述内筒体的下端还连接有一挡块,所述挡块为类圆柱体,所述挡块的上下两端的直径均小于所述挡块的中部的直径。进一步地,所述调节挡板的数量为25-35块,25-35块所述调节均匀分布于同一圆周上。进一步地,所述调节挡板的两端对应通过转轴转动连接于所述内筒体筒壁和所述外壳体上。进一步地,所述外壳体和内筒体均为锥体。进一步地,所述外壳体的侧壁还开设有带有窗扇的观察窗口,所述窗扇与所述外壳体的位于所述观察窗口周缘处的侧壁铰接。进一步地,所述外 ...
