空氣(qi)輸(shu)送斜(xie)槽簡稱輸(shu)送斜(xie)槽、空氣(qi)斜(xie)槽，是利用氣(qi)流沿管路輸(shu)送散粒物(wu)料的裝置(zhi)，可(ke)用于水泥、粉(fen)(fen)煤灰等易流態(tai)化的粉(fen)(fen)狀物(wu)料。

       空氣輸送斜(xie)槽是由若干(gan)個普通薄鋼板制成的(de)槽子與其它(ta)附件用螺栓聯接而(er)成。槽子上、下殼體(ti)之(zhi)間夾有透氣層(ceng),斜(xie)槽整體(ti)與水平傾斜(xie)一定角度。

       空氣(qi)輸送(song)斜槽有吸送(song)式、壓送(song)式和混合式三種。空氣(qi)斜槽的輸送(song)量受(shou)很(hen)多因(yin)素的影響,往往變化(hua)很(hen)大。

       ①吸送式(shi)空(kong)氣輸(shu)送斜槽。抽(chou)風機啟(qi)動后，整(zheng)個(ge)系統呈一定的(de)真空(kong)度(du)，在(zai)壓(ya)差作用下空(kong)氣流使(shi)物(wu)料(liao)進入吸嘴，并沿輸(shu)料(liao)管送至卸(xie)料(liao)處(chu)的(de)分離器(qi)內,物(wu)料(liao)從空(kong)氣流中分離后由分離器(qi)底卸(xie)出,氣流經(jing)除塵器(qi)凈化后再經(jing)消聲(sheng)器(qi)排入大氣。優點是供料(liao)簡單，能從數(shu)處(chu)同時吸取(qu)物(wu)料(liao)。但輸(shu)送距離短，生產率(lv)低(di)。密封性(xing)要求高(gao)。

       ②壓送(song)式(shi)空(kong)氣輸(shu)送(song)斜槽。鼓(gu)風機(ji)將空(kong)氣壓入(ru)輸(shu)送(song)管，物料(liao)從供料(liao)器供入(ru)，空(kong)氣和物料(liao)的(de)混(hun)合物沿(yan)輸(shu)料(liao)管被壓送(song)至卸(xie)料(liao)處(chu),物料(liao)經分離器后(hou)卸(xie)出,空(kong)氣經除塵器凈(jing)化后(hou)排入(ru)大氣。特點與吸送(song)式(shi)相反(fan),可(ke)同時(shi)將物料(liao)輸(shu)送(song)到幾處(chu),輸(shu)送(song)距離較長，生產率較高，但(dan)結構復雜。

       ③混(hun)合式空氣(qi)輸(shu)(shu)送(song)(song)(song)斜槽(cao)。為上述兩種形式的(de)組合。XZ型(xing)空氣(qi)輸(shu)(shu)送(song)(song)(song)斜槽(cao)采(cai)用高(gao)壓離心風機為動力(li)(li)源(yuan)，使(shi)物(wu)料(liao)在密(mi)閉的(de)輸(shu)(shu)送(song)(song)(song)斜槽(cao)中(zhong)能保持流(liu)(liu)(liu)態(tai)化的(de)向(xiang)下(xia)傾斜的(de)流(liu)(liu)(liu)動，從而達到輸(shu)(shu)送(song)(song)(song)水(shui)泥、粉煤灰等(deng)易流(liu)(liu)(liu)態(tai)化的(de)粉狀物(wu)料(liao)的(de)目的(de)，輸(shu)(shu)送(song)(song)(song)斜槽(cao)與其它的(de)輸(shu)(shu)送(song)(song)(song)設(she)備(bei)相比具有輸(shu)(shu)送(song)(song)(song)能力(li)(li)大(da)，保證物(wu)料(liao)不受潮等(deng)等(deng)優點。輸(shu)(shu)送(song)(song)(song)斜槽(cao)以高(gao)壓離心風機（9-19：9-26型(xing)）為動力(li)(li)源(yuan)，使(shi)密(mi)閉輸(shu)(shu)送(song)(song)(song)斜槽(cao)中(zhong)的(de)物(wu)料(liao)保持流(liu)(liu)(liu)態(tai)化向(xiang)傾斜向(xiang)下(xia)的(de)一端緩慢(man)的(de)流(liu)(liu)(liu)動。該(gai)設(she)備(bei)主體部(bu)分無傳動部(bu)件，密(mi)封操作管理方便，設(she)備(bei)重(zhong)量輕，電耗(hao)少，輸(shu)(shu)送(song)(song)(song)能力(li)(li)大(da)，容易改變輸(shu)(shu)送(song)(song)(song)方向(xiang)，采(cai)用新型(xing)涂淪透氣(qi)層等(deng)等(deng)優點。
