高真空绝热双层球罐
本专利技术涉及双层球形储罐
,特别涉及一种高真空绝热双层球罐。
技术介绍
高真空绝热双层球罐主要用于储存低温液体介质,是低温系统的关键设备。在国家大力提倡环保、节能的产业政策下,高真空绝热双层球罐在低温液体贮运设备市场获得了广泛认可,具有巨大的发展空间。目前,高真空绝热双层球罐主要由内球罐、外球罐及支撑结构等部件组成,内球罐通过支撑结构支撑于外球罐中,因此需在外球罐上开孔以供支撑结构穿过外球罐,而开孔之后再用补强板封住,易出现装配精度不精准、焊接困难,焊接质量不能保证,变形大、成型不好,费时费工等问题,进而影响了球罐的密封效果和保温效果。
技术实现思路
本专利技术的目的在于提供一种安装方便、密封效果和保温效果好的高真空绝热双层球罐。为解决上述技术问题,本专利技术提供一种高真空绝热双层球罐,包括内球罐、外球罐、多个内球罐支撑结构和多个外部套筒;内球罐外表面包覆有高真空保温材料;外球罐包裹所述内球罐,且与所述内球罐之间形成有夹层空间,所述外球罐底部设有多个开孔;多个内球罐支撑结构固定连接于所述内球罐底部以支撑所述内球罐,各内球罐支撑结构一一穿过所述外球罐的开孔;多个外部套筒固定连接于所述外球罐底部的开孔处,且一一对应套设于所述内球罐支撑结构外部,并与所述内球罐支撑结构固定连接,所述外部套筒的内部空间与所述夹层空间相通,且为密闭空间。优选地,每个所述外部套筒均包括上下端开口、内部中空的套筒本体和固定连接于所述套筒本体下端的封板;所述套筒本体套设于所述内球罐支撑结构外部且两者之间有间隔,所述套筒本体的上端与所述外球罐底部固定焊接,所述封板与所 ...
