產(chan)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。
烘干機筒體(ti)部分由三個同軸水平放置的(de)內、中(zhong)、外筒套疊組成，這(zhe)就使筒體(ti)的(de)截面(mian)得到充分的(de)利用(yong)。其(qi)筒體(ti)外形(xing)總(zong)長(chang)度(du)約為與(yu)之相當的(de)單筒的(de)30-35%。從(cong)而大幅度(du)地減少(shao)占地面(mian)積和廠(chang)房建(jian)筑面(mian)積。
該(gai)機的支承裝置，是(shi)在外筒上輪帶與托(tuo)輪支承，由電(dian)機直接帶動(dong)托(tuo)輪。通過托(tuo)輪與輪帶摩擦，使筒體轉動(dong)。該(gai)機總體結(jie)構緊湊、合(he)理、簡單，為(wei)便于磨損(sun)件(jian)的檢修更換，在中間設計成(cheng)軸向剖分式，用螺栓(shuan)固定連接。
工(gong)作原理
物(wu)(wu)(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)入(ru)回轉滾(gun)筒(tong)的(de)(de)(de)內層(ceng)(ceng)(ceng),實現順流烘(hong)干,物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下不斷抄(chao)起、散(san)落(luo)呈(cheng)螺旋行(xing)(xing)進(jin)(jin)式實現熱交換，物(wu)(wu)(wu)(wu)料(liao)移動至內層(ceng)(ceng)(ceng)的(de)(de)(de)另一端(duan)(duan)進(jin)(jin)入(ru)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)逆流烘(hong)干，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)不斷地被反復(fu)揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步(bu)退一步(bu)的(de)(de)(de)行(xing)(xing)進(jin)(jin)方式，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)(chong)分吸收內層(ceng)(ceng)(ceng)滾(gun)筒(tong)散(san)發的(de)(de)(de)熱量(liang)，又(you)吸收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)熱量(liang)，同時(shi)又(you)延長了干燥(zao)時(shi)間，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此達(da)到干燥(zao)狀態(tai)。物(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)另一端(duan)(duan)而落(luo)入(ru)外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒(tong)內呈(cheng)矩(ju)形多回路方式行(xing)(xing)進(jin)(jin)，達(da)到干燥(zao)效果(guo)的(de)(de)(de)物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)熱風作用下快速行(xing)(xing)進(jin)(jin)排出(chu)滾(gun)筒(tong)，沒有達(da)到干燥(zao)效果(guo)的(de)(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)因(yin)自重而不能(neng)快速行(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此矩(ju)形抄(chao)板(ban)內進(jin)(jin)行(xing)(xing)充(chong)(chong)分干燥(zao)，由此完成(cheng)干燥(zao)目(mu)的(de)(de)(de)。
