Description

变螺距螺旋槽沉没辊
技术领域
本发明涉及热镀锌技术领域，尤其是一种热镀锌装置上的沉没辊。
背景技术
沉没辊为热镀锌线上的重要设备之一，其材质为不锈钢，在生产时需要将沉没辊整体沉浸在熔化的锌液中，并且在镀锌板的拖动下随之旋转。在镀锌过程中，铝、铁、锌合金元素会附着在辊面上，形成不均匀的结瘤，即粘渣；另外，辊子运转过程中锌液会经常会堆积在辊子中间，不流动的锌液与辊子发生接触，也同样产生锌铁合金附着于辊子表面。上述现象随时间的推移而加重，使带钢产生拱包、凸起，从而严重影响镀锌板的产品质量。这种情况下，不得不频繁更换粘渣的沉没辊，而影响生产，增加劳动强度，也造成资源浪费。为解决上述问题，现有技术的沉没辊以辊筒轴向对称中心线为分界线，在分界线两侧辊筒表面设有相反旋向的螺旋槽，使铝锌铁合金元素在沉没辊旋转作用下自动进入螺旋槽内，再沿螺旋槽的螺旋方向送至辊子两端，减少铝锌铁合金元素在辊子表面形成结瘤，这样，可提高产品质量，减少劳动强度，节约资源。但现有技术的沉没辊也存在一定的缺陷：由于螺旋槽为等螺距螺旋槽，铝锌铁合金元素在螺旋槽流动时流动速度基本一致，越往两侧流动时阻力越大，因此造成流动不畅，少部分在辊子表面形成结瘤，影响产品质量，增加劳动强度，并造成资源浪费。
发明内容
本发明针对现有技术的不足，提供一种使铝锌铁合金元素在螺旋槽流动畅通，彻底解决辊子表面形成结瘤问题的变螺距螺旋槽沉没辊。
本发明通过下述技术方案实现技术目标。
变螺距螺旋槽沉没辊，包括辊筒、两个辊轴、两个连接轴套；所述连接轴套是由小端、大端连成的阶梯式结构，大端为法兰盘；所述辊筒两端的止口孔套装在连接轴套法兰盘上，并固定连接；所述连接轴套小端套装在辊轴端部，并固定连接；以所述辊筒轴向对称中心线为分界线，在分界线两侧辊筒表面设有相反旋向的螺旋槽；其改进之处在于：所述连接轴套法兰盘外圆周设有外螺纹，所述辊筒两端止口孔设有内螺纹，所述辊筒两端止口孔与连接轴套法兰盘螺纹连接；所述螺旋槽从分界线向两侧螺距越来越大。
上述结构中，所述螺旋槽的底部为圆弧形。
上述结构中，所述连接轴套小端与辊轴端部连接处设有1个以上防松螺钉，所述防松螺钉螺纹连接并径向贯穿连接轴套小端孔壁，插入辊轴端部。
本发明与现有技术相比，具有以下积极效果：
1、辊筒、连接轴套通过螺纹连接，辊筒、连接轴套组装或拆开方便快捷，显著提高辊筒、连接轴套组装或拆开效率。
2、螺旋槽从分界线向两侧螺距越来越大，这样铝锌铁合金元素在螺旋槽流动时流动阻力越来越小，流动畅通，彻底解决辊子表面形成结瘤问题。
3、螺旋槽的底部为圆弧形，可取得更好的输送效果。
4、连接轴套小端与辊轴端部连接处设有1个以上防松螺钉，防止连接轴套、辊轴端部连接处产生松动，与防松螺钉Ⅰ组成双重防松结构。
