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(tong)體(ti)部分(fen)由三個同軸水平放置的(de)內、中、外筒(tong)套疊組成，這(zhe)就使筒(tong)體(ti)的(de)截面(mian)(mian)得到充(chong)分(fen)的(de)利用。其筒(tong)體(ti)外形總長(chang)度約(yue)為(wei)與之相當的(de)單筒(tong)的(de)30-35%。從而大幅度地(di)減(jian)少占地(di)面(mian)(mian)積和廠房建(jian)筑(zhu)面(mian)(mian)積。

該機(ji)的支承裝置，是在(zai)外(wai)筒(tong)上輪(lun)帶與(yu)托(tuo)輪(lun)支承，由電機(ji)直接(jie)帶動(dong)托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶摩擦，使筒(tong)體(ti)轉動(dong)。該機(ji)總體(ti)結構緊湊、合理、簡單，為便于磨(mo)損件的檢修更(geng)換，在(zai)中間設計成(cheng)軸向(xiang)剖(pou)分式，用螺栓固定連接(jie)。

工作(zuo)原理

物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進(jin)(jin)入回(hui)轉滾筒(tong)(tong)的(de)(de)內層(ceng)(ceng)(ceng)(ceng)(ceng),實現順(shun)流(liu)烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在內層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下不斷(duan)(duan)抄(chao)起(qi)、散(san)落呈(cheng)螺旋行(xing)進(jin)(jin)式實現熱(re)(re)交換，物(wu)(wu)(wu)料(liao)(liao)移動(dong)至內層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)另一(yi)(yi)(yi)端進(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)逆流(liu)烘干(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)不斷(duan)(duan)地被反復揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步退(tui)一(yi)(yi)(yi)步的(de)(de)行(xing)進(jin)(jin)方(fang)式，物(wu)(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)既充分吸(xi)(xi)收(shou)內層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)散(san)發的(de)(de)熱(re)(re)量，又(you)吸(xi)(xi)收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)的(de)(de)熱(re)(re)量，同時又(you)延長(chang)了干(gan)(gan)燥時間，物(wu)(wu)(wu)料(liao)(liao)在此達(da)到干(gan)(gan)燥狀(zhuang)態(tai)。物(wu)(wu)(wu)料(liao)(liao)行(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)另一(yi)(yi)(yi)端而落入外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)內呈(cheng)矩形多(duo)回(hui)路方(fang)式行(xing)進(jin)(jin)，達(da)到干(gan)(gan)燥效果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)(liao)在熱(re)(re)風作用下快速行(xing)進(jin)(jin)排出滾筒(tong)(tong)，沒有達(da)到干(gan)(gan)燥效果(guo)的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重而不能快速行(xing)進(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)在此矩形抄(chao)板內進(jin)(jin)行(xing)充分干(gan)(gan)燥，由此完成干(gan)(gan)燥目的(de)(de)。
