烘干(gan)機的結構(gou)性(xing)能特點
1、熱交(jiao)換(huan)效率高(gao)：改進設備加熱中(zhong)心(xin)X形揚(yang)料(liao)板，減少熱空洞(dong)，延(yan)長物料(liao)停(ting)留時間，提高(gao)熱交(jiao)換(huan)效率，減少高(gao)溫氣體的流失。
2、作業效率高(gao)：烘干過(guo)程(cheng)中能實現(xian)與強(qiang)風交換，蒸發出的(de)(de)水分又被強(qiang)風帶走。兩個(ge)小時左右就能達到(dao)成分的(de)(de)干燥效果。
3、內(nei)部結構更合理：強化了對已分散物料的(de)清掃和熱傳(chuan)導(dao)作用，徹底(di)解決了筒體(ti)內(nei)壁的(de)粘結現象。
污(wu)泥烘干(gan)(gan)機(ji)的烘干(gan)(gan)原理
污(wu)(wu)泥(ni)(ni)由給(gei)料(liao)(liao)(liao)機(ji)經溜槽進(jin)入干(gan)(gan)燥(zao)(zao)機(ji)內導料(liao)(liao)(liao)板(ban)(ban)上，隨著筒(tong)(tong)體(ti)(ti)的(de)轉(zhuan)動(dong)(dong)，污(wu)(wu)泥(ni)(ni)被(bei)導至(zhi)傾斜(xie)揚(yang)(yang)料(liao)(liao)(liao)板(ban)(ban)上即被(bei)提(ti)(ti)升(sheng)到(dao)筒(tong)(tong)體(ti)(ti)的(de)中心位(wei)置，逐漸灑落形成(cheng)料(liao)(liao)(liao)幕，高(gao)溫氣流(liu)從中穿過(guo)，使污(wu)(wu)泥(ni)(ni)預熱(re)并(bing)蒸(zheng)(zheng)(zheng)發(fa)部分水(shui)分。當(dang)污(wu)(wu)泥(ni)(ni)灑落、移動(dong)(dong)到(dao)活動(dong)(dong)的(de)篦條式(shi)(shi)翼板(ban)(ban)上時(shi)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)又(you)與預熱(re)過(guo)的(de)篦條式(shi)(shi)翼板(ban)(ban)夾(jia)雜在一(yi)起(qi)，將(jiang)熱(re)量傳給(gei)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)，使部分水(shui)分蒸(zheng)(zheng)(zheng)發(fa)。同(tong)時(shi)，翼板(ban)(ban)夾(jia)帶(dai)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)提(ti)(ti)起(qi)、灑落，重復多次，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)與熱(re)氣流(liu)進(jin)行對流(liu)和接觸熱(re)交換。同(tong)時(shi)埋在物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)中的(de)清(qing)掃裝置，也(ye)沿圓弧形揚(yang)(yang)料(liao)(liao)(liao)板(ban)(ban)的(de)里側下(xia)滑(hua)，把揚(yang)(yang)料(liao)(liao)(liao)板(ban)(ban)內壁粘附(fu)的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)清(qing)掃下(xia)來(lai)。當(dang)清(qing)掃裝置隨筒(tong)(tong)體(ti)(ti)轉(zhuan)過(guo)垂直線以后(hou)(hou)，又(you)在圓弧揚(yang)(yang)料(liao)(liao)(liao)板(ban)(ban)背面拖(tuo)動(dong)(dong)，將(jiang)其粘附(fu)在揚(yang)(yang)料(liao)(liao)(liao)板(ban)(ban)外壁的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)清(qing)掃下(xia)來(lai)。隨著筒(tong)(tong)體(ti)(ti)的(de)不斷轉(zhuan)動(dong)(dong)，使部分水(shui)分蒸(zheng)(zheng)(zheng)發(fa)，污(wu)(wu)泥(ni)(ni)得到(dao)進(jin)一(yi)步干(gan)(gan)燥(zao)(zao)。同(tong)時(shi)，清(qing)掃裝置對污(wu)(wu)泥(ni)(ni)團球也(ye)起(qi)到(dao)了打(da)碎(sui)作用，提(ti)(ti)高(gao)了干(gan)(gan)燥(zao)(zao)速度(du)， 污(wu)(wu)泥(ni)(ni)干(gan)(gan)燥(zao)(zao)后(hou)(hou)變成(cheng)低水(shui)分的(de)松散物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)，由出料(liao)(liao)(liao)口排出。
