Description

旋转接头及旋转方法
本发明明属旋转接头制造领域，主要用于尿素造粒机及化工行业。
本发明的背景技术：现有的旋转接头，由于其结构设计满足于常压常温一般流体通过的工艺要求，而对高温、高速及具有遇冷凝固的流体化工行业，则显得无能为力，而无法使用。
本发明的设计目的：避免背景技术中的不足之处，设计一种能够在高温、高速及流体遇冷凝固条件下，正常开机工作的旋转接头。
本发明的设计方案：1、旋转接头的旋转方法，主轴与转芯联接，位于转芯上的上、下锥盘同转芯一起随主轴作同步运动，与上、下锥盘密封配合的密封锥环只能在弹簧的作用下沿轴线反方向移动而不能作圆周转动。转芯随主轴作同步运动，转芯上的上、下两个锥盘与密封锥环呈旋转摩擦密封。2、旋转接头，转芯(1)与主轴轴头联接，上锥盘(2)与转芯(1)联为一体，主轴旋转时，转芯(1)随主轴作同步运动，转芯(1)上下两个锥盘与密封锥环(3，15)旋转摩擦密封、密封锥环(3，15)靠弹簧(9)的弹力与转芯(1)锥面，上锥盘(2)锥面紧密贴合，弹簧座(7)外圆上的轴向键槽在固定在壳体(6)上的弹簧座止转销(8)的作用下只能作轴向移动而不能作旋转运动，密封锥环(3，15)端面上的定位孔中用锥环止转销(4，14)将其限向，止转销(4，14)的另一端插在静止状态的弹簧座(7)和壳体(6)中，故当转芯(1)旋转时上下两个密封环(3，15)只能靠弹簧(9)的作用作沿轴线反方向移动而不能作圆周转动，密封锥环(3，15)外缘的环型倒角使O型密封圈(5，13)通过弹簧(9)的张力令O型橡胶截面变形而紧贴在壳体(6)的内壁上形成局部密封，液体经进料弯管进入壳体(6)，再经转芯(1)中部数个腰型孔进入(1)内，靠熔液自重排出。转芯(1)的上、下两个锥盘的面为锥面或球面，与之相匹配的密封锥环的形状为锥形环或凹形球面环。
本发明与背景技术相比：一是转芯上下两个锥盘与密封环旋转摩擦密封结构的设计，不仅保证旋转接头的高速旋转工作，而且实现了高速旋转摩擦密封；二是弹簧座外圆上轴向键槽在固定在壳体上的弹簧座止转销的作用下只能作轴向移动而不能作旋转运动的结构设计，与锥环止转销两端分别位于密封锥环端面定位孔内和静止状的弹簧座、壳体中的结构设计，实现了当转芯旋转时，上下两个密封锥环只能靠弹簧的作用沿轴线反方向移动而不能作圆周转动，保证O型密封圈的可靠密封性能。
附图说明：
图1是本发明的结构示意图。
实施例1：旋转接头的旋转方法，主轴与转芯联接，位于转芯上的上、下锥盘同转芯一起随主轴作同步运动，与上，下锥盘密封配合的密封锥环只能在弹簧的作用下沿轴线反方向移动而不能作圆周转动。转芯随主轴作同步运动，转芯上的上、下两个锥盘与密封锥环呈旋转摩擦密封。转芯(1)的上、下两个锥盘的面为锥面或球面，与之相匹配的密封锥环的形状为锥形环或凹形球面环。
实施例2：旋转接头，转芯(1)的内锥与造粒机主轴轴头用标准工业锥度联接，螺钉(12)、平垫(10)及弹簧垫圈(11)将转芯(1)与造粒机主轴联为一体，上锥盘(2)通过螺纹连接与转芯(1)联为一体，当造粒机主轴旋转时，转芯(1)随主轴作同步运动，转芯(1)上下两个锥盘与密封锥环(3，15)旋转摩擦密封、密封锥环(3，15)靠弹簧(9)的弹力与转芯(1)锥面、上锥盘(2)锥面紧密贴合，弹簧座(7)外圆上的轴向键槽在固定在壳体(6)上的弹簧座止转销(3)的作用下只能作轴向移动而不能作旋转运动，密封锥环(3，15)端面上的定位孔中用锥环止转销(4，14)将其限向，止转销(4，14)的另一端插在静止状态的弹簧座(7)和壳体(6)中，故当转芯(1)旋转时上下两个密封环(3，15)只能靠弹簧(9)的作用作沿轴线反方向移动而不能作圆周转动，密封锥环(3，15)外缘的环型倒角使O型密封圈(5，13)通过弹簧(9)的张力令O型橡胶截面变形而紧贴在壳体(6)的内壁上形成局部密封，熔融液经进料弯管进入壳体(6)，再经转芯(1)中部数个腰型孔进入(1)内，靠熔液自重进入造粒喷头。旋转接头的侧部开有进料孔、转芯(1)中部开有数个腰型孔且与转芯的中心进料孔相通。
实施例3：在实施例的基础上，转芯(1)的上、下两个锥盘的面为锥面或球面，与之相匹配的密封锥环的形状为锥形环或凹形球面环。
