The invention relates to a monolithic multi-element compound flue gas type inner tube for the flue gas type shrinkage part of the preheater of a cement kiln, which comprises a main board, the main board is divided into a square shape and a cylinder shape, the upper end of the back side of the main board is provided with a plurality of installation protective sleeves, the center of the installation protective sleeve is provided with an installation fixing hole, the installation fixing hole is provided with a lengthening bolt, and the cylinder is The body is hoisted into the smoke-type shrinkage hole, and fixed on the inner wall of the smoke chamber shrinkage hole through the installation fixing hole by lengthening bolt. The middle of the main board is smooth, and the shrinkage hole is completely surrounded by 360 degrees. The invention has strong anti-scaling ability, because of the high temperature and severe scaling at the shrinkage area of the flue gas chamber, hardly any scaling after use, and does not need to stop the kiln frequently to deal with the scaling phenomenon, thus saving the cost and improving the production efficiency of the cement plant; anti-corrosion, anti-oxidation, heat-resistant and wear-resistant, anti-scaling, long service period, and saving the cost without continuous replacement. It saves labor, and designs different specifications of the cylinder according to needs, and the production is more convenient.

一种水泥窑预热器用整体形多元素复合烟式缩口内筒
本专利技术具体涉及一种水泥窑预热器烟式缩口部位用整体形多元素复合烟式缩口内筒。
技术介绍
目前国内水泥窑烟室缩口部位采用焊接锚固件打上浇注料使用,由于该部位使用温度高,结皮严重,造成预热器的堵料,堵料会造成风速的改变影响生产,并且造成堵料停产,一至二个月就要停窑处理浇注料结皮现象,由于工人清理结皮有一定的危险性,所以处理时相当麻烦,以及该部位易落损坏,要胶注料固定于烟室需要昂贵的费用,水泥生产企业停窑一天的造成的损失费用分析:2500T/D的水泥生线损失费用为20万左右;5000T/D的水泥生线损失费用为30万左右。耗费人工耗费时间耗费成本,采用整体形多元素复合烟式缩口内筒(缩口改造)组件以后,情况发生根本变化,不需要经常停窑处理结皮现象,解决了根本性问题,节约了时间,节约了成本,同时也节省了人工,提高产能。用整套缩口板在烟式缩口部位烧坏变形的情况下,做成整体形筒体,在平地将有配件安装完毕后,用吊机将其整体吊入至烟式缩口部位。方便了施工作业,提高了工作效率。
技术实现思路
本专利技术的目的在于一种水泥窑预热器烟式缩口部位用整体形多元素复合烟式缩口内筒,以解决现有的技术问题。为实现上述目的,本专利技术提供如下技术方案:一种水泥窑预热器烟式缩口部位用整体形多元素复合烟式缩口内筒,包括主板,主板分为方体形和圆柱体形,主板背面的上端设有多个安装保护套,安装保护套中心设有安装固定孔,安装固定孔上设有加长螺栓,安装固定孔用加长螺栓贯穿主板固定在烟室缩口内壁上,主板中间成平滑状。本专利技术的进一步改进在于:主板套在烟式缩口内, ...
