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)體(ti)部分由三(san)個同軸水平放置的內(nei)、中、外筒(tong)套疊組成,這就使筒(tong)體(ti)的截(jie)面(mian)得到充(chong)分的利用。其筒(tong)體(ti)外形(xing)總長度約為與之相當的單(dan)筒(tong)的30-35%。從(cong)而(er)大幅度地(di)減(jian)少占地(di)面(mian)積和廠(chang)房建筑面(mian)積。
該(gai)機(ji)的(de)支(zhi)承裝置,是在外筒上(shang)輪(lun)帶(dai)與(yu)托輪(lun)支(zhi)承,由(you)電機(ji)直接(jie)帶(dai)動(dong)托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒體轉(zhuan)動(dong)。該(gai)機(ji)總(zong)體結構緊湊、合理、簡單,為便于磨(mo)損件的(de)檢(jian)修更(geng)換,在中間設計成軸向(xiang)剖分式,用(yong)螺栓(shuan)固定連接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)入(ru)回(hui)轉滾(gun)筒(tong)的(de)內層(ceng)(ceng),實(shi)現順流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)內層(ceng)(ceng)的(de)抄(chao)(chao)板(ban)下(xia)不斷抄(chao)(chao)起、散(san)落(luo)呈(cheng)螺旋行進(jin)(jin)(jin)式(shi)實(shi)現熱(re)交換,物(wu)(wu)(wu)料(liao)(liao)移動(dong)至(zhi)內層(ceng)(ceng)的(de)另一端進(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)(jin)行逆流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)不斷地(di)被反復(fu)揚進(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)兩(liang)步退(tui)一步的(de)行進(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)既(ji)充分吸(xi)收內層(ceng)(ceng)滾(gun)筒(tong)散(san)發的(de)熱(re)量,又(you)吸(xi)收中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)熱(re)量,同時又(you)延長了干(gan)燥(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)此達到(dao)干(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行至(zhi)中(zhong)(zhong)層(ceng)(ceng)另一端而落(luo)入(ru)外(wai)(wai)層(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)外(wai)(wai)層(ceng)(ceng)滾(gun)筒(tong)內呈(cheng)矩(ju)形(xing)多(duo)回(hui)路方式(shi)行進(jin)(jin)(jin),達到(dao)干(gan)燥(zao)(zao)效果的(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)熱(re)風作(zuo)用下(xia)快速行進(jin)(jin)(jin)排(pai)出滾(gun)筒(tong),沒有達到(dao)干(gan)燥(zao)(zao)效果的(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重(zhong)而不能快速行進(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)此矩(ju)形(xing)抄(chao)(chao)板(ban)內進(jin)(jin)(jin)行充分干(gan)燥(zao)(zao),由此完成干(gan)燥(zao)(zao)目(mu)的(de)。
