1、摘要閾柩狽嵋忙傾洎尾幢和側(cè)梁激振脫水篩是直線振動(dòng)篩的一種,主要用于煤泥脫水,是選煤廠的重要設(shè)備之一。咴辦繇揪撙頸仔反猬豐傳統(tǒng)的直線振動(dòng)脫水篩,一般結(jié)構(gòu)較復(fù)雜,機(jī)體較笨重,而且能耗高,為此研制了一種新型的脫水篩。側(cè)梁激振脫水篩與其它振動(dòng)篩相比具有如下結(jié)構(gòu)優(yōu)點(diǎn):攥槭孬餳具薰幬獨(dú)肯凡(1)單位面積處理量是普通振動(dòng)篩的2倍以上;氏醬架鼗攝鏈毪擼捷黲(2)拋射角度合適,拋射強(qiáng)度高,振幅大,單位處理能力的能耗較小,與同面積的篩子相比,成本可降低20%;銥牽撩偽嗍富聱背撞煜(3)電動(dòng)機(jī)與箱式激振器激振軸采用橡膠聯(lián)軸器(即撓性聯(lián)接或軟聯(lián)接),可補(bǔ)償電機(jī)軸線與偏心軸軸線不同心造成的誤差。耘勐麝輒泊寫誰瓷涵怪
