Description

开炼机辊筒和电加热棒的连接密封结构
技术领域
      本发明涉及一种在辊筒中腔安装有电加热元件的开炼机辊筒，具体涉及开炼机辊筒和电加热棒的连接密封结构。
背景技术
      现有的加工橡胶用开炼机辊筒，因加工工艺需求，需对辊筒加热，一般在辊筒的空腔内通入导热油、并通过插装于辊筒轴向的电加热棒对导热油进行加热，进而使辊筒达到工艺需求的温度。但现有的开炼机辊筒和电加热棒的连接结构其密封性能差，易导致导热油泄漏。
发明内容
      针对上述问题，本发明提供了开炼机辊筒和电加热棒的连接密封结构，其密封性能好，能有效防止导热油泄漏。
      其技术方案是这样的，开炼机辊筒和电加热棒的连接密封结构，包括辊筒和电加热棒，所述电加热棒插装于所述辊筒的支撑端轴向，其特征在于：所述辊筒的支撑端设有安装槽，位于所述安装槽内，所述电加热棒沿其轴向依次套设有密封圈一、压头、弹簧、止推环，位于所述密封圈一外侧，所述电加热棒上套设有端盖，所述端盖与所述安装槽螺纹连接，所述压头、止推环与所述电加热棒连接的孔壁上分别嵌设有密封圈二、密封圈三，所述安装槽的底部设有环状的连接槽，所述连接槽的底部设有若干组叠加的密封圈四，所述止推环的环状体部位插入所述连接槽内。
      其进一步特征在于：
      所述压头的轴向外端面设有锥形的定位凸起，所述密封圈一的轴向内端面设有与所述定位凸起配合的锥形槽；
      所述压头的轴向内端面、所述止推环的轴向外端面分别设有用于卡装所述弹簧的沟槽；
      所述密封圈三为Y型密封圈，所述密封圈四为V型密封圈。
      采用本发明的结构后，端盖内侧设有密封圈一，压头、止推环与电加热棒连接的孔壁上分别嵌设有密封圈二、密封圈三，安装槽的底部设有连接槽，连接槽的底部设有若干组叠加的密封圈四，止推环的环状体部位插入连接槽内，多重密封设置，提高其连接密封性能，避免导热油泄漏；并且在弹簧的作用下，使得压头、止推环分别顶紧密封圈一、密封圈四，进一步加强其密封性能，防止导热油泄漏。
附图说明
      图1为本发明的结构示意图。
具体实施方式
