LFB-75型氣力輸送設備-粉體輸送系統免費安裝調試
粉粒狀物料輸送的管道化、密封化、自動化是現代散裝物料輸送技術的發展方向，而氣力輸送技術無疑是實現粉粒狀物料物流技術的zui*途徑之一。粉體氣力輸送機設備顯著的特(te)點是(shi)動力(li)(li)(li)(li)源是(shi)具有一定能量的氣(qi)流，簡化了傳統(tong)復雜的機械裝置(zhi)；其次，封閉式管道(dao)(dao)運輸，布置(zhi)簡單靈活；第三，沒(mei)有循環。氣(qi)力(li)(li)(li)(li)輸送根(gen)據輸送管道(dao)(dao)內壓(ya)力(li)(li)(li)(li)是(shi)否高于(yu)大(da)氣(qi)壓(ya)力(li)(li)(li)(li)分為(wei)氣(qi)力(li)(li)(li)(li)吸(xi)力(li)(li)(li)(li)輸送和氣(qi)力(li)(li)(li)(li)壓(ya)力(li)(li)(li)(li)輸送兩種基本類(lei)型。
氣(qi)(qi)(qi)(qi)動(dong)吸(xi)(xi)(xi)料(liao)(liao)采用(yong)負壓(ya)(ya)形式(shi)，依(yi)靠系統末(mo)(mo)端的風機來吸(xi)(xi)(xi)取和輸(shu)送(song)(song)(song)(song)(song)物(wu)料(liao)(liao)。因為氣(qi)(qi)(qi)(qi)動(dong)吸(xi)(xi)(xi)力(li)(li)輸(shu)送(song)(song)(song)(song)(song)是利用(yong)管(guan)(guan)道(dao)內(nei)(nei)的負壓(ya)(ya)將(jiang)(jiang)空(kong)氣(qi)(qi)(qi)(qi)和物(wu)料(liao)(liao)吸(xi)(xi)(xi)入管(guan)(guan)道(dao)內(nei)(nei)，依(yi)靠大氣(qi)(qi)(qi)(qi)壓(ya)(ya)力(li)(li)將(jiang)(jiang)物(wu)料(liao)(liao)輸(shu)送(song)(song)(song)(song)(song)到目的地。風機安裝在管(guan)(guan)道(dao)系統末(mo)(mo)端，因此(ci)氣(qi)(qi)(qi)(qi)力(li)(li)吸(xi)(xi)(xi)力(li)(li)輸(shu)送(song)(song)(song)(song)(song)稱為負壓(ya)(ya)氣(qi)(qi)(qi)(qi)力(li)(li)輸(shu)送(song)(song)(song)(song)(song)；氣(qi)(qi)(qi)(qi)動(dong)壓(ya)(ya)力(li)(li)輸(shu)送(song)(song)(song)(song)(song)是利用(yong)管(guan)(guan)道(dao)內(nei)(nei)高于大氣(qi)(qi)(qi)(qi)壓(ya)(ya)的正(zheng)壓(ya)(ya)氣(qi)(qi)(qi)(qi)流攜帶或推(tui)動(dong)物(wu)料(liao)(liao)進(jin)行輸(shu)送(song)(song)(song)(song)(song)。風機安裝在管(guan)(guan)道(dao)系統的起始端，因此(ci)氣(qi)(qi)(qi)(qi)力(li)(li)輸(shu)送(song)(song)(song)(song)(song)也稱為正(zheng)壓(ya)(ya)氣(qi)(qi)(qi)(qi)力(li)(li)輸(shu)送(song)(song)(song)(song)(song)。氣(qi)(qi)(qi)(qi)力(li)(li)輸(shu)送(song)(song)(song)(song)(song)設備(bei)主要由(you)給料(liao)(liao)機、輸(shu)送(song)(song)(song)(song)(song)管(guan)(guan)道(dao)、分(fen)離器、氣(qi)(qi)(qi)(qi)源設備(bei)、除塵器及其他輔助(zhu)部分(fen)組成。
給料機是一種能夠定量供給或排出粉狀、顆粒狀物料的設備。在氣力輸送機裝置中，給(gei)料(liao)(liao)(liao)(liao)機(ji)的作(zuo)用是將物料(liao)(liao)(liao)(liao)喂入(ru)輸送(song)管道(dao)，物料(liao)(liao)(liao)(liao)與空(kong)氣(qi)充分(fen)混合，然后由氣(qi)流加速輸送(song)。給(gei)料(liao)(liao)(liao)(liao)機(ji)的結構和性能(neng)對氣(qi)力(li)輸送(song)生產線的輸送(song)量、穩(wen)定性和能(neng)耗影(ying)響很大。特(te)別是正壓氣(qi)力(li)輸送(song)，給(gei)料(liao)(liao)(liao)(liao)機(ji)性能(neng)的*壞將影(ying)響整個氣(qi)力(li)輸送(song)系統能(neng)否(fou)正常運行。
輸(shu)(shu)送(song)管(guan)道是氣力輸(shu)(shu)送(song)生產(chan)線中物料輸(shu)(shu)送(song)的(de)通道。主(zhu)要是指連(lian)接(jie)給(gei)料機(ji)和卸(xie)料機(ji)之間的(de)管(guan)道部分(fen)。一(yi)般(ban)由直(zhi)管(guan)、彎管(guan)、分(fen)流閥等組成。
分離器(qi)是物料(liao)由送料(liao)管輸(shu)送到所需位置后(hou)，必(bi)須將物料(liao)與氣流分離的(de)(de)裝置。它(ta)也被稱為卸載器(qi)。氣力輸(shu)送系統中的(de)(de)分離器(qi)和除塵器(qi)本質(zhi)上(shang)是相(xiang)同的(de)(de)。*一(yi)的(de)(de)區別是分離機對產量、物料(liao)破碎率(lv)低等有一(yi)定的(de)(de)要求，有時產量還比(bi)較大。
氣(qi)源設備可以提供氣(qi)力(li)輸送(song)生產線所需的*部壓(ya)(ya)力(li)和(he)風(feng)量。可選用羅茨(ci)鼓(gu)風(feng)機(ji)(ji)、高壓(ya)(ya)離(li)心風(feng)機(ji)(ji)、空氣(qi)壓(ya)(ya)縮機(ji)(ji)等。
除(chu)塵(chen)器(qi)(qi)(qi)(qi)，由于卸(xie)料(liao)器(qi)(qi)(qi)(qi)的(de)分離效率不可能達(da)到(dao)100%，所以物(wu)料(liao)與空氣(qi)(qi)的(de)混合物(wu)通過(guo)卸(xie)料(liao)器(qi)(qi)(qi)(qi)后，從卸(xie)料(liao)器(qi)(qi)(qi)(qi)排出的(de)空氣(qi)(qi)中(zhong)仍含有(you)一些顆粒細(xi)小(xiao)的(de)物(wu)料(liao)或粉塵(chen)；為了使(shi)空氣(qi)(qi)排放濃(nong)度達(da)到(dao)環保排放標準要(yao)求、回收有(you)價(jia)值(zhi)的(de)物(wu)質、經(jing)濟損失和減少風機磨損等，需要(yao)安(an)裝(zhuang)除(chu)塵(chen)器(qi)(qi)(qi)(qi)。氣(qi)(qi)力(li)輸送生產線常(chang)用(yong)的(de)除(chu)塵(chen)器(qi)(qi)(qi)(qi)有(you)袋式除(chu)塵(chen)器(qi)(qi)(qi)(qi)和離心(xin)式除(chu)塵(chen)器(qi)(qi)(qi)(qi)。
