The utility model discloses a corrugated pipe coupling for a desulfurization gray spiral conveyor, which comprises a metal corrugated pipe. The two ends of the corrugated pipe are welded with earboards, the outer sides of the earboards are welded with short nozzles, the right short nozzles are fixed with fixed sleeves, and the fixed sleeves are inserted in the inner part of the metal corrugated pipe. The left side walls of the fixed sleeves are provided with moving incisions, and the right side of the fixed sleeves are welded with spiral conveyor shafts The inner part of the left end of the fixed sleeve is equipped with the axle connecting pipe, and the outer walls of the right end of the axle connecting pipe are equipped with positioning rotating blocks. The positioning rotating blocks are inserted in the movable incision. The outer side of the axle connecting pipe wall is welded with ring flange, which can be detachably and fixedly connected with the left short connecting pipe through bolts. The two ends of the double-ended pull rod bolts pass through the ear plates on both sides and the nuts on both ends to fix them. The utility model effectively compensates the additional stress caused by the thermal expansion deformation of the screw conveyor shaft when the temperature exceeds 400 C, avoids the deformation or damage of the screw conveyor shaft caused by the additional stress, and has reliable and convenient connection.

一种脱硫灰螺旋输送机用波纹管联轴器
本技术涉及以干法、半干法烟气脱硫副产物综合利用
,尤其涉及一种脱硫灰螺旋输送机用波纹管联轴器。
技术介绍
由于干法、半干法脱硫设备投资少、占地面积小、节水节能、无废水废酸排放等优点,在我国约有30%的电力行业燃煤机组和90%以上的钢铁企业烧结机组均采用干法、半干法脱硫工艺进行脱硫,使其被广泛采用。由于干法、半干法脱硫以CaCO3或Ca(OH)2为脱硫剂,产生的副产物为浅白色干粉状物质—脱硫灰。由于脱硫灰中的CaSO3在适合的温度、时间、湿度、氧气条件下可以氧化成CaSO4,并代替天然石膏广泛用于建材、建筑和装修等领域。应用该工艺及装置的脱硫灰是在两段式回转氧化窑内完成CaSO3转化为CaSO4的氧化过程,窑内温度控制在550~600℃之间,因此现有的螺旋输送机及其所使用的普通旋转轴、由于受温度超过400℃以上的影响容易产生热涨形变,已经不能满足出窑脱硫灰输送。因此,现在需要一种能够解决上述问题的脱硫灰螺旋输送机用波纹管联轴器,使其用于螺旋输送机旋转轴连接用。
