Steel inner cylinder chimney in flange-free flexible sealed connection
The invention discloses a steel inner cylinder chimney in flange-free flexible sealed connection. The steel inner cylinder chimney comprises an inner cylinder and an outer cylinder, the inner cylinderis formed by splicing upper-section inner cylinder bodies and lower-section inner cylinder bodies, the outer cylinder is formed by splicing upper-section outer cylinder bodies and lower-section outercylinder bodies, and the upper-section inner cylinder bodies and the lower-section inner cylinder bodies are connected through telescopic elastic sleeve assemblies. Each telescopic elastic sleeve assembly is composed of spring assemblies and a movable shell ring. Each spring assembly comprises a pull rod fixing piece, a pull rod and a pull rod guiding piece, wherein the pull rod is sleeved with acompression spring, and the lower end of the pull rod penetrates through the pull rod guiding piece and then is provided with a locking nut. Each movable shell ring comprises a movable shell ring straight section and a movable shell ring conical section, an inverted-cone-shaped cylinder completely matched with the movable shell ring conical section is arranged at the top end of the correspondinglower-section inner cylinder body, and after the upper-section inner cylinder bodies and the lower-section inner cylinder bodies are installed, the movable shell ring conical sections are tightly pressed and attached to the inner side walls of the inverted-cone-shaped cylinders under the action of the compression springs. Flange installation of the inner cylinder is omitted, installation time is shortened, and installation efficiency is improved.
本发明公开了一种无法兰柔性密封连接的钢内筒烟囱，包括：内筒、外筒，内筒由上段内筒及下段内筒拼接而成，外筒由上段外筒及下段外筒拼接而成，上段内筒及下段内筒之间通过可伸缩弹性套筒组件相连接，可伸缩弹性套筒组件由弹簧组件和活动筒节组成，弹簧组件包括拉杆固定件、拉杆、拉杆导向件，拉杆上套设压缩弹簧，且下端贯穿拉杆导向件后安装锁紧螺母；活动筒节包括活动筒节直段和活动筒节锥段，下段内筒的顶端具有与活动筒节锥段完全匹配的倒锥形筒，上段内筒及下段内筒安装完毕后，活动筒节锥段在压缩弹簧的作用下紧压贴合于所述倒锥形筒的内侧壁上。本发明免去了内筒的法兰安装，减少了安装时间，提高了安装效率。
