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。

烘干機筒(tong)(tong)(tong)體部分由三個同軸水平(ping)放置(zhi)的(de)內、中、外(wai)筒(tong)(tong)(tong)套疊組(zu)成，這就使筒(tong)(tong)(tong)體的(de)截面(mian)得到充分的(de)利用。其筒(tong)(tong)(tong)體外(wai)形(xing)總長(chang)度(du)(du)約為與之相當(dang)的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而(er)大幅度(du)(du)地(di)減(jian)少占地(di)面(mian)積和廠房建(jian)筑面(mian)積。

該機的支承(cheng)裝(zhuang)置，是在外筒(tong)上(shang)輪帶與托輪支承(cheng)，由電(dian)機直接帶動托輪。通(tong)過托輪與輪帶摩(mo)擦(ca)，使筒(tong)體(ti)轉動。該機總體(ti)結(jie)構緊湊、合(he)理、簡單(dan)，為便于(yu)磨(mo)損件的檢修更換(huan)，在中(zhong)間設計成軸(zhou)向剖分式，用螺栓固定連接。

工作(zuo)原理(li)

物(wu)(wu)(wu)料(liao)由供料(liao)裝(zhuang)置進(jin)(jin)入回轉滾筒的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現(xian)順流烘(hong)干(gan),物(wu)(wu)(wu)料(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下不斷抄起、散落(luo)呈(cheng)(cheng)螺(luo)旋行進(jin)(jin)式(shi)實現(xian)熱(re)交(jiao)換(huan)，物(wu)(wu)(wu)料(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一端(duan)(duan)進(jin)(jin)入中層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行逆(ni)流烘(hong)干(gan)，物(wu)(wu)(wu)料(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚進(jin)(jin)，呈(cheng)(cheng)進(jin)(jin)兩步退一步的(de)(de)行進(jin)(jin)方式(shi)，物(wu)(wu)(wu)料(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)既充(chong)分吸(xi)收內(nei)層(ceng)(ceng)(ceng)(ceng)滾筒散發的(de)(de)熱(re)量，又吸(xi)收中層(ceng)(ceng)(ceng)(ceng)滾筒的(de)(de)熱(re)量，同時又延長了干(gan)燥(zao)(zao)時間，物(wu)(wu)(wu)料(liao)在(zai)此(ci)達到干(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)行至中層(ceng)(ceng)(ceng)(ceng)另一端(duan)(duan)而落(luo)入外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾筒內(nei)呈(cheng)(cheng)矩形多(duo)回路方式(shi)行進(jin)(jin)，達到干(gan)燥(zao)(zao)效(xiao)果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)在(zai)熱(re)風作(zuo)用下快(kuai)(kuai)速行進(jin)(jin)排出滾筒，沒有達到干(gan)燥(zao)(zao)效(xiao)果(guo)的(de)(de)濕物(wu)(wu)(wu)料(liao)因(yin)自(zi)重而不能快(kuai)(kuai)速行進(jin)(jin)，物(wu)(wu)(wu)料(liao)在(zai)此(ci)矩形抄板內(nei)進(jin)(jin)行充(chong)分干(gan)燥(zao)(zao)，由此(ci)完成干(gan)燥(zao)(zao)目的(de)(de)。
