產品結構
大型三筒烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒,以縮短烘干機體的外形尺寸。該機工作時,物料和熱氣流依次進入內至外筒體,在機體Z形往復折流后,充分利用熱能烘干物料后再卸出。
烘干機筒體部分由三個同軸水平放置的(de)內、中、外(wai)筒套疊組成,這就使筒體的(de)截面得(de)到充分的(de)利(li)用。其筒體外(wai)形(xing)總長度(du)約為與之相當(dang)的(de)單筒的(de)30-35%。從(cong)而大幅度(du)地減少占(zhan)地面積(ji)和廠房建筑面積(ji)。
該機的支(zhi)承裝置(zhi),是在外(wai)筒上輪(lun)帶(dai)與托輪(lun)支(zhi)承,由電機直接帶(dai)動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩擦,使筒體(ti)轉動(dong)。該機總體(ti)結構緊湊、合理、簡單,為便于磨損件的檢(jian)修更換(huan),在中間設計成軸向(xiang)剖(pou)分式,用螺栓固定連接。
工(gong)作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)入回轉滾(gun)(gun)筒(tong)的內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的抄(chao)板下不斷抄(chao)起、散落呈(cheng)(cheng)螺旋(xuan)行(xing)進(jin)(jin)式(shi)實現熱(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的另(ling)一端進(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行(xing)逆(ni)流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚進(jin)(jin),呈(cheng)(cheng)進(jin)(jin)兩(liang)步退一步的行(xing)進(jin)(jin)方(fang)式(shi),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的熱(re)量,又吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的熱(re)量,同時又延長了干(gan)(gan)燥時間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)達到干(gan)(gan)燥狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端而(er)落入外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)(nei)呈(cheng)(cheng)矩形多回路(lu)方(fang)式(shi)行(xing)進(jin)(jin),達到干(gan)(gan)燥效果(guo)的物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱(re)風作(zuo)用(yong)下快速行(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達到干(gan)(gan)燥效果(guo)的濕(shi)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自(zi)重(zhong)而(er)不能快速行(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)矩形抄(chao)板內(nei)(nei)進(jin)(jin)行(xing)充分干(gan)(gan)燥,由此(ci)完成干(gan)(gan)燥目(mu)的。
