產品結構
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(tong)體(ti)(ti)部分(fen)由三個同軸(zhou)水平(ping)放置的內、中、外筒(tong)套疊組(zu)成，這就使筒(tong)體(ti)(ti)的截面(mian)(mian)得到充(chong)分(fen)的利用。其筒(tong)體(ti)(ti)外形總長度(du)(du)約為與之相當的單(dan)筒(tong)的30-35%。從而大幅度(du)(du)地(di)減(jian)少占地(di)面(mian)(mian)積(ji)和廠房建筑面(mian)(mian)積(ji)。
該(gai)機的支(zhi)承(cheng)裝置，是在外(wai)筒(tong)上輪(lun)(lun)帶與(yu)托輪(lun)(lun)支(zhi)承(cheng)，由電(dian)機直接帶動(dong)托輪(lun)(lun)。通過(guo)托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩(mo)擦，使筒(tong)體轉(zhuan)動(dong)。該(gai)機總體結構(gou)緊湊、合理、簡單，為便于磨損件的檢(jian)修(xiu)更換，在中間設計成(cheng)軸向剖(pou)分式，用螺栓固定連接。
工作原理
物(wu)(wu)料(liao)(liao)由(you)供(gong)料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入回(hui)轉(zhuan)滾(gun)筒(tong)(tong)的(de)(de)內(nei)(nei)層(ceng)(ceng),實現順流烘(hong)(hong)干,物(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)的(de)(de)抄(chao)(chao)板下(xia)不(bu)(bu)斷抄(chao)(chao)起(qi)、散(san)落呈(cheng)螺(luo)旋(xuan)行(xing)進(jin)(jin)(jin)(jin)式實現熱(re)交換，物(wu)(wu)料(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)(jin)(jin)入中層(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)逆流烘(hong)(hong)干，物(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)不(bu)(bu)斷地被反(fan)復(fu)揚進(jin)(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)(jin)兩(liang)步退一步的(de)(de)行(xing)進(jin)(jin)(jin)(jin)方(fang)式，物(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)既充(chong)分吸收(shou)內(nei)(nei)層(ceng)(ceng)滾(gun)筒(tong)(tong)散(san)發的(de)(de)熱(re)量(liang)，又吸收(shou)中層(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)熱(re)量(liang)，同時(shi)又延長了干燥(zao)時(shi)間(jian)，物(wu)(wu)料(liao)(liao)在(zai)此(ci)達到干燥(zao)狀態(tai)。物(wu)(wu)料(liao)(liao)行(xing)至中層(ceng)(ceng)另(ling)一端而落入外層(ceng)(ceng)，物(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)(nei)呈(cheng)矩形多回(hui)路方(fang)式行(xing)進(jin)(jin)(jin)(jin)，達到干燥(zao)效(xiao)果的(de)(de)物(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用下(xia)快(kuai)速行(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒(tong)(tong)，沒有達到干燥(zao)效(xiao)果的(de)(de)濕物(wu)(wu)料(liao)(liao)因自重而不(bu)(bu)能快(kuai)速行(xing)進(jin)(jin)(jin)(jin)，物(wu)(wu)料(liao)(liao)在(zai)此(ci)矩形抄(chao)(chao)板內(nei)(nei)進(jin)(jin)(jin)(jin)行(xing)充(chong)分干燥(zao)，由(you)此(ci)完成干燥(zao)目的(de)(de)。
