Description

一种铜管在线自动吹扫装置 技术领域
本实用新型涉及铜管生产设备技术领域，具体涉及一种铜管在线自动吹扫装置。
背景技术
铜管在拉拔的过程中要加入起润滑作用的拉拔油，而退火后的成品盘管又对管内外壁残油量有严格的限制，因此铜管盘管需要在退火的工艺过程中对其内壁进行吹扫。
参见图1，图中给出的是现有的铜管在线自动吹扫装置，包括铜管吹扫密封座10以及硅胶管20，铜管吹扫密封座10内构成有一供铜管1***的圆柱状密封腔体11，圆柱状密封腔体11的一端位于铜管吹扫密封座10的侧壁上并形成为一铜管***口11a，其另一端封闭，在圆柱状密封腔体11的中部形成有一对对称间隔设置的圆环部11b、11c，硅胶管20的两端分别套设在圆环部11b、11c上，在铜管吹扫密封座10内还构成有一压缩空气输送通道12和一氮气输送通道13，压缩空气输送通道12的一端与圆柱状密封腔体11连通且位于圆环部11b、11c之间，其另一端通过管路与空气压缩机的供气端连接，氮气输送通道13的一端与圆柱状密封腔体11形成封闭的那一端连通，其另一端与氮气制备装置的供气端连接。工作时，先将铜管1的一端从铜管***口11a进入圆柱状密封腔体11内，并延伸至略微超出圆环部11c的位置，硅胶管20包覆在铜管1进入圆柱状密封腔体11内的管体的外管面上。接着，空气压缩机产生的压缩气体经由压缩空气输送通道12进入圆柱状密封腔体11内，压缩空气对硅胶管20的外管面进行施压，使得硅胶管20向中心变形， 并抱紧铜管1位于圆环部11b、11c之间的外管面形成密封。此时，氮气制备装置产生的氮气经由氮气输送通道13进入圆柱状密封腔体11内，从铜管1的尾端进入铜管1的内腔，实现在线吹扫铜管内腔，排除铜管内腔加热产生的油烟。但是，现有的铜管在线自动吹扫装置在持续生产过程中存在以下一些问题：1、硅胶管20使用3～5次后会出现回弹不充分的问题，由于一次在线吹扫氮气过程持续一个多小时，硅胶管20长时间的压瘪状态会使其回弹不充分，硅胶管20的形状由圆形变成椭圆形两侧内凹，这种形状造成下次再自动穿管时，铜管1自动穿入受阻，管口容易戳破硅胶管20造成漏气。一旦发生漏气的情况，氮气的密封型腔形成不了，就会使氮气吹扫漏气或者连带压缩空气一并吹入铜管，造成铜管内壁氧化及内壁残油超标。2、由于硅胶管20漏气，造成抱紧铜管的力减小或消失。铜管1一旦失去抱紧力，就有可能在料框高速旋转过程中离心甩出铜管吹扫密封座10，造成铜管报废。
目前，有中国专利授权公告号为CN209363186U公开了一种铜管在线自动吹扫装置，该专利通过空气压缩机对充气密封圈进行充气膨胀以抱紧铜管，再通过氮气制备装置对铜管进行吹扫以达到自动吹扫效果，但该专利的充气密封圈需要操作进气和排气两个步骤，在持续生产的情况下会造成充气密封圈的回弹不充分，同样存在着现有技术的问题。
