廣州低壓氣力輸送機-電石粉粉末真空上料機
在水(shui)泥廠中，常(chang)用的(de)設備(bei)(bei)(bei)是輸(shu)(shu)(shu)送設備(bei)(bei)(bei)，其中水(shui)平輸(shu)(shu)(shu)送設備(bei)(bei)(bei)占60%以上。輸(shu)(shu)(shu)送粉狀物料常(chang)見的(de)水(shui)平輸(shu)(shu)(shu)送設備(bei)(bei)(bei)是螺旋輸(shu)(shu)(shu)送機(ji)、FU鏈式輸(shu)(shu)(shu)送機(ji)、空氣輸(shu)(shu)(shu)送斜槽。為了提高大家對水(shui)平輸(shu)(shu)(shu)送設備(bei)(bei)(bei)的(de)認(ren)識和選擇，大宇(yu)機(ji)械對三(san)類設備(bei)(bei)(bei)的(de)特點對比如下：
(1)螺旋(xuan)輸(shu)送(song)機
螺旋輸(shu)送機具(ju)有應用范(fan)圍(wei)廣的優點。可(ke)輸(shu)送原料(liao)、水泥、煤粉(fen)等，可(ke)水平輸(shu)送或20°以(yi)內傾斜輸(shu)送；它既(ji)可(ke)以(yi)輸(shu)送干(gan)粉(fen)狀物料(liao)，也可(ke)以(yi)輸(shu)送粘性(xing)濕物料(liao)。材料(liao)。但其(qi)阻力大(da)、功耗(hao)大(da)、易(yi)損(sun)件(jian)多、維護工(gong)作量大(da)、安裝精度要求高、密(mi)封困難。
(2)FU鏈式輸送(song)機
FU鏈式(shi)(shi)輸(shu)送機(ji)運行時噪音低(di)、能耗低(di)、無粉體(ti)污(wu)染(ran)。另外，它(ta)不需(xu)要像螺旋(xuan)輸(shu)送機(ji)那(nei)樣每(mei)隔2~3m放置一個(ge)油杯，因此維護(hu)非常方便，近年來得到了廣泛的應(ying)用。特別適用于輸(shu)送序列長、磨損大的場合。當地面(mian)螺旋(xuan)輸(shu)送機(ji)輸(shu)送距離(li)超過(guo)30m時，輸(shu)送軸較(jiao)長，同(tong)心(xin)困難。往往需(xu)要兩(liang)端傳輸(shu)，消耗大量(liang)電(dian)力。雖然FU鏈式(shi)(shi)輸(shu)送機(ji)在替代蝶(die)式(shi)(shi)輸(shu)送機(ji)方面(mian)具有諸多優勢，但實(shi)踐證明(ming)FU鏈式(shi)(shi)輸(shu)送機(ji)的維護(hu)成本并不低(di)。
(3)空氣(qi)輸送斜槽
氣力輸送機是利用(yong)空(kong)氣使固體顆粒呈流(liu)化狀態(tai)流(liu)動的(de)輸(shu)(shu)(shu)(shu)送(song)(song)(song)設(she)備。屬于(yu)密相流(liu)態(tai)化輸(shu)(shu)(shu)(shu)送(song)(song)(song)。與(yu)螺旋輸(shu)(shu)(shu)(shu)送(song)(song)(song)機、FU鏈式輸(shu)(shu)(shu)(shu)送(song)(song)(song)機相比，具有以(yi)(yi)下優點：結構(gou)簡(jian)單(dan)，易于(yu)使用(yong)維護和(he)檢查，無(wu)運(yun)動部件(jian)，磨損小，耐用(yong)；滌綸布作為透(tou)氣層，使用(yong)壽命長；密封性*、無(wu)噪音、輸(shu)(shu)(shu)(shu)送(song)(song)(song)能(neng)(neng)(neng)力大(da)(da)；可改變輸(shu)(shu)(shu)(shu)送(song)(song)(song)方向，方便多點進料、多點卸料；具有功耗低、運(yun)行(xing)安*可靠等優點，缺點是不能(neng)(neng)(neng)輸(shu)(shu)(shu)(shu)送(song)(song)(song)大(da)(da)塊、粘性和(he)高度(du)潮(chao)濕的(de)物料。它不能(neng)(neng)(neng)向上輸(shu)(shu)(shu)(shu)送(song)(song)(song)，只(zhi)能(neng)(neng)(neng)以(yi)(yi)一定的(de)向下坡度(du)輸(shu)(shu)(shu)(shu)送(song)(song)(song)。一般(ban)輸(shu)(shu)(shu)(shu)送(song)(song)(song)距離(li)(li)不超過100m。當輸(shu)(shu)(shu)(shu)送(song)(song)(song)距離(li)(li)較(jiao)大(da)(da)時，落差較(jiao)大(da)(da)，給工藝布置(zhi)和(he)土建設(she)計帶來困難。另外(wai)，為了(le)便于(yu)排氣，需要在風槽末端(duan)安裝簡(jian)單(dan)的(de)排氣裝置(zhi)，例如使用(yong)獨立的(de)除塵(chen)器或使用(yong)簡(jian)易的(de)布袋進行(xing)排氣。
