產品結構
三筒式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(gan)機筒體(ti)部分由三個同軸水平放置的內、中、外筒套(tao)疊組成，這就使筒體(ti)的截面(mian)得(de)到充分的利用(yong)。其筒體(ti)外形總長度(du)約為與之相當的單筒的30-35%。從而大幅度(du)地減少占(zhan)地面(mian)積和廠房建筑面(mian)積。
該(gai)機的支承裝置，是在外筒(tong)上(shang)輪(lun)(lun)帶與托輪(lun)(lun)支承，由(you)電機直(zhi)接帶動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦，使筒(tong)體轉動。該(gai)機總體結構緊湊、合理、簡單，為便于磨損(sun)件的檢(jian)修更換，在中(zhong)間(jian)設計成軸向(xiang)剖分式，用(yong)螺栓固定連接。
工作(zuo)原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置進(jin)(jin)入回轉滾(gun)筒(tong)的內層(ceng)(ceng)(ceng)(ceng),實(shi)現順(shun)流(liu)烘(hong)干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)的抄板(ban)下不(bu)斷(duan)抄起、散落呈(cheng)螺旋(xuan)行(xing)(xing)(xing)進(jin)(jin)式實(shi)現熱交換，物(wu)(wu)(wu)料(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)(ceng)的另一端進(jin)(jin)入中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)逆流(liu)烘(hong)干(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被(bei)反(fan)復揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩(liang)步退一步的行(xing)(xing)(xing)進(jin)(jin)方式，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸收內層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的熱量，又吸收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的熱量，同時又延長了干(gan)燥(zao)(zao)時間(jian)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此達到(dao)干(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另一端而落入外(wai)層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內呈(cheng)矩形多回路方式行(xing)(xing)(xing)進(jin)(jin)，達到(dao)干(gan)燥(zao)(zao)效果(guo)(guo)的物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱風作用(yong)下快速行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)筒(tong)，沒(mei)有達到(dao)干(gan)燥(zao)(zao)效果(guo)(guo)的濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自(zi)重而不(bu)能快速行(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此矩形抄板(ban)內進(jin)(jin)行(xing)(xing)(xing)充分(fen)干(gan)燥(zao)(zao)，由(you)此完成干(gan)燥(zao)(zao)目(mu)的。
