一种空分精馏塔涨圈的紧固装置
本技术涉及空分精馏塔
,尤其涉及一种空分精馏塔涨圈的紧固装置。
技术介绍
空分冷箱内精馏塔设备在空气分离中起到关键作用,这就要保证精馏塔内部零件安装的重要性,在安装的涨圈、塔板、筒体须相互精密配合在一起。但现有技术中,精馏塔涨圈的安装过程中无法有效的控制涨圈与精馏塔筒体的间隙,导致间隙过大,容易产生焊接变形,如果间隙过大将影响塔板的安装精度,最终导致精馏塔精馏效率的降低。为此,申请号为201620328071.9的中国技术专利公开了一种空分精馏塔涨圈的紧固装置,所述的涨圈沿着空分精馏塔的筒体内壁布置,所述的紧固装置主要由定位销、连接块、轴销、锁紧螺母与锁紧螺纹接头组合而成,所述的左右两定位销插接在左右两连接块内,并通过焊接连接成一体;将左右锁紧螺母与锁紧螺纹接头通过螺纹连接,将连接好的左右两锁紧螺母通过各自的凹槽端插入在左右连接块内,并用销轴进行固定,左右两定位销分别插接在涨圈的相应两个工艺孔中;销轴上设置有用于开口销插入以防止销轴使用时滑出的销轴止推孔;左右两定位销的二端距离通过调整与涨圈上开设的工艺孔距离相同,使左右两定位销 ...
