氣力粉體輸送設備-物料輸送系統生產廠家
在水泥廠中，常用的設備是粉體氣力輸送設備，其中水平輸送設備占60%以上。輸送粉狀物料常見的水平輸送設備是螺旋輸送機、FU鏈式輸送機、空氣輸送斜槽。為了提高大家(jia)對(dui)(dui)水平輸送設備的(de)認識和選擇，大宇機械對(dui)(dui)三類設備的(de)特點對(dui)(dui)比如(ru)下：
(1)螺旋輸送機
螺(luo)旋輸(shu)送(song)(song)機具有應用范(fan)圍廣的優點。可(ke)(ke)輸(shu)送(song)(song)原料、水(shui)泥、煤粉(fen)(fen)等(deng)，可(ke)(ke)水(shui)平輸(shu)送(song)(song)或20°以(yi)內傾(qing)斜輸(shu)送(song)(song)；它既可(ke)(ke)以(yi)輸(shu)送(song)(song)干粉(fen)(fen)狀物料，也可(ke)(ke)以(yi)輸(shu)送(song)(song)粘性(xing)濕物料。材(cai)料。但其阻力大、功耗大、易損件多、維護工(gong)作量大、安(an)裝精(jing)度要求高、密封(feng)困難。
(2)FU鏈式輸送(song)機(ji)
FU鏈式(shi)(shi)輸(shu)送(song)機(ji)運行(xing)時(shi)(shi)噪音低、能(neng)耗(hao)低、無粉體污染(ran)。另外，它不需(xu)要像螺(luo)(luo)旋(xuan)輸(shu)送(song)機(ji)那樣每隔2~3m放置一個油杯，因(yin)此(ci)維(wei)護非常方便，近(jin)年(nian)來得到了廣泛的應(ying)用。特別適用于輸(shu)送(song)序列長、磨(mo)損大的場(chang)合。當地面螺(luo)(luo)旋(xuan)輸(shu)送(song)機(ji)輸(shu)送(song)距離超過(guo)30m時(shi)(shi)，輸(shu)送(song)軸較長，同心困難。往(wang)往(wang)需(xu)要兩端傳(chuan)輸(shu)，消耗(hao)大量電(dian)力。雖然FU鏈式(shi)(shi)輸(shu)送(song)機(ji)在(zai)替代(dai)蝶(die)式(shi)(shi)輸(shu)送(song)機(ji)方面具有諸多優勢，但實踐證明FU鏈式(shi)(shi)輸(shu)送(song)機(ji)的維(wei)護成(cheng)本并不低。
(3)空(kong)氣(qi)輸(shu)送斜槽
氣力輸送機是(shi)利用(yong)空氣使(shi)固體顆粒呈流(liu)化狀態(tai)流(liu)動(dong)的(de)輸(shu)送(song)(song)設備。屬于密相流(liu)態(tai)化輸(shu)送(song)(song)。與(yu)螺旋輸(shu)送(song)(song)機(ji)和(he)(he)FU鏈(lian)式(shi)輸(shu)送(song)(song)機(ji)相比(bi)，具有以(yi)下優點(dian)(dian)(dian)：結構(gou)簡(jian)單，易(yi)于使(shi)用(yong)維護和(he)(he)檢(jian)查(cha)，無運動(dong)部件，磨損低(di)(di)，耐用(yong)；滌綸布作為透氣層(ceng)，使(shi)用(yong)壽命長(chang)；密封性*、無噪音、輸(shu)送(song)(song)能(neng)(neng)力大(da)(da)；可改變(bian)輸(shu)送(song)(song)方向(xiang)，方便(bian)多點(dian)(dian)(dian)進料、多點(dian)(dian)(dian)卸料；具有功耗低(di)(di)、運行安(an)*可靠等優點(dian)(dian)(dian)，缺點(dian)(dian)(dian)是(shi)不能(neng)(neng)輸(shu)送(song)(song)大(da)(da)塊、粘性和(he)(he)高(gao)度潮濕(shi)的(de)物料。它不能(neng)(neng)向(xiang)上(shang)輸(shu)送(song)(song)，只能(neng)(neng)以(yi)一定的(de)向(xiang)下坡度輸(shu)送(song)(song)。一般輸(shu)送(song)(song)距離不超過(guo)100m。當(dang)輸(shu)送(song)(song)距離較大(da)(da)時，落差較大(da)(da)，給(gei)工藝布置(zhi)和(he)(he)土(tu)建設計帶來困難。另(ling)外，為了便(bian)于排氣，需要在風槽末端安(an)裝簡(jian)單的(de)排氣裝置(zhi)，例如使(shi)用(yong)獨立的(de)除塵器(qi)或使(shi)用(yong)簡(jian)易(yi)的(de)布袋進行排氣。
