產(chan)品結(jie)構
三筒(tong)(tong)烘(hong)干(gan)機(ji)是通過對單(dan)筒(tong)(tong)烘(hong)干(gan)機(ji)的單(dan)筒(tong)(tong)體(ti)(ti)改為(wei)套(tao)疊在(zai)一起的三筒(tong)(tong)，以縮短(duan)烘(hong)干(gan)機(ji)體(ti)(ti)的外(wai)形尺寸。該機(ji)工作時(shi)，物料(liao)和熱氣流依次進入內至(zhi)外(wai)筒(tong)(tong)體(ti)(ti)，在(zai)機(ji)體(ti)(ti)Z形往復折(zhe)流后(hou)，充(chong)分利(li)用熱能烘(hong)干(gan)物料(liao)后(hou)再卸(xie)出。
烘干機筒體部分由(you)三個(ge)同軸水平放置的內、中、外(wai)筒套疊組(zu)成，這就使筒體的截面得(de)到充分的利用(yong)。其筒體外(wai)形總(zong)長度(du)約為與之相(xiang)當的單筒的30-35%。從而大幅度(du)地減少占地面積和廠(chang)房建筑面積。
該機的(de)支(zhi)承(cheng)裝置(zhi)，是在外(wai)筒(tong)(tong)上輪(lun)(lun)帶與托輪(lun)(lun)支(zhi)承(cheng)，由電機直接(jie)帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦，使(shi)筒(tong)(tong)體轉動(dong)。該機總體結構緊湊、合(he)理、簡(jian)單(dan)，為便于磨損件的(de)檢(jian)修更換，在中間設計成軸向剖分式，用螺栓固定連接(jie)。
工作(zuo)原理
物(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入回(hui)轉滾筒的(de)(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng),實(shi)現(xian)順流烘干(gan),物(wu)料(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄板下不(bu)斷抄起、散落(luo)呈(cheng)螺旋行(xing)進(jin)(jin)(jin)(jin)式實(shi)現(xian)熱交換(huan)，物(wu)料(liao)(liao)移動至(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)逆流烘干(gan)，物(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷地被反(fan)復揚進(jin)(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)(jin)兩(liang)步退一步的(de)(de)(de)行(xing)進(jin)(jin)(jin)(jin)方(fang)(fang)式，物(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分(fen)吸收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)滾筒散發的(de)(de)(de)熱量(liang)，又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒的(de)(de)(de)熱量(liang)，同時又延長了(le)干(gan)燥(zao)時間，物(wu)料(liao)(liao)在(zai)(zai)此(ci)達(da)到(dao)干(gan)燥(zao)狀態。物(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另一端而落(luo)入外(wai)(wai)層(ceng)(ceng)(ceng)，物(wu)料(liao)(liao)在(zai)(zai)外(wai)(wai)層(ceng)(ceng)(ceng)滾筒內(nei)(nei)呈(cheng)矩形多回(hui)路方(fang)(fang)式行(xing)進(jin)(jin)(jin)(jin)，達(da)到(dao)干(gan)燥(zao)效果(guo)的(de)(de)(de)物(wu)料(liao)(liao)在(zai)(zai)熱風作(zuo)用下快速(su)行(xing)進(jin)(jin)(jin)(jin)排(pai)出滾筒，沒(mei)有達(da)到(dao)干(gan)燥(zao)效果(guo)的(de)(de)(de)濕物(wu)料(liao)(liao)因自重而不(bu)能快速(su)行(xing)進(jin)(jin)(jin)(jin)，物(wu)料(liao)(liao)在(zai)(zai)此(ci)矩形抄板內(nei)(nei)進(jin)(jin)(jin)(jin)行(xing)充(chong)分(fen)干(gan)燥(zao)，由此(ci)完成干(gan)燥(zao)目的(de)(de)(de)。
