气力提升泵概况
粉体气力提升泵 属于一种低压空气输送物料设备(气力输灰泵),适用于连续,均匀地垂直提升输送干燥粉状物质,其输送能力较大且提升高度较高,在水泥工业中被广泛地用于给带预热器窑的窑尾提升供应生料,此外在冶金,化工行业中日益被广泛应用。
气力提升泵输送系统主要由泵体,输送管道及气源三部分组成,LG型气力提升泵具有占地面积小,安装方便,运行可靠,操作简捷,在运行过程中设备本身几乎无磨损,工作时泵体内部无压力,故其上部给料管道不需要锁风装置;且提升泵还可以克服喂料设备瞬间喂料不均匀造成的供料波动现象。
气力提升泵分类
气力提升泵按输送物料的种类可分为固液相提升泵、粉料提升泵;
其工作原理都是利用高速气流将物料经管道输送至指定地点,它的功能除了提升,更重要的是要把物料输送到指定的位置。

气力提升泵工作原理
气力提升泵相当于一台低压流态化仓罐,提升泵的上部为泵体,下部为气化室,中间隔有多孔透气板。一次风出口装有喷嘴,对准输料管:输料管下部出口装有膨胀仓,二次风与气化室相连,透过透气层,将灰吹起形成瘫态化状态;输送的物料随来自喷嘴的压缩空气流通过提升管向上输送。其风量由球阀来调节,气源由罗茨风机供给。
打开气源阀门给气力提升泵进风管供气,同时调节流化气风管上的球阀,使物料在提升泵下部的流化仓内充分流化,这时当供给进风管的气源压力达到额定值时,由喷嘴高速喷出的空气流产生的牵引力引导已被流化的粉状物料沿着泵体*的输送管及外接的管道提升至所需高度。
