空气输送斜槽其工作原理

Time: 2016/11/2 10:20:57

空气输送斜槽 ,空气输送斜槽利用气流沿管路输送散粒物料的装置。有吸送式、压送式和混合式三种。其工作原理是利用气流的动能使散粒物料呈悬浮状态随气流沿管道输送:   
    ①吸送式。抽风机启动后,整个系统呈一定的真空度,在压差作用下空气流使物料进入吸嘴,并沿输料管送至卸料处的分离器内,物料从空气流中分离后由分离器底卸出,气流经除尘器净化后再经消声器排入大气。优点是供料简单,能从数处同时吸取物料。但输送距离短,生产率低。密封性要求高。   
    ②压送式。鼓风机将空气压入输送管,物料从供料器供入,空气和物料的混合物沿输料管被压送至卸料处,物料经分离器后卸出,空气经除尘器净化后排入大气。特点与吸送式相反,可同时将物料输送到几处,输送距离较长,生产率较高,但结构复杂。   
    ③混合式。为上述两种形式的组合。
