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(tong)體部(bu)分由三個同軸水平(ping)放置的(de)內、中、外筒(tong)套疊組成,這就使(shi)筒(tong)體的(de)截面得到充(chong)分的(de)利用。其筒(tong)體外形總長度(du)約為與之相當的(de)單筒(tong)的(de)30-35%。從而大幅度(du)地減(jian)少(shao)占地面積和廠(chang)房建筑面積。
該(gai)機的支(zhi)承(cheng)裝置,是在(zai)外筒上輪(lun)(lun)帶與托輪(lun)(lun)支(zhi)承(cheng),由電(dian)機直(zhi)接帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦,使筒體轉動(dong)。該(gai)機總體結構緊湊、合理、簡單,為便于磨(mo)損件的檢修(xiu)更換,在(zai)中間設計成(cheng)軸(zhou)向(xiang)剖(pou)分式,用(yong)螺栓固(gu)定連接。
工作原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)入(ru)回轉滾(gun)(gun)筒(tong)的內層(ceng)(ceng)(ceng),實現順流烘(hong)干(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在內層(ceng)(ceng)(ceng)的抄(chao)板下(xia)不(bu)斷抄(chao)起、散落(luo)呈(cheng)螺(luo)旋行(xing)進(jin)(jin)式(shi)(shi)實現熱交換,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移(yi)動至內層(ceng)(ceng)(ceng)的另一(yi)(yi)端進(jin)(jin)入(ru)中層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)逆流烘(hong)干(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在中層(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復(fu)揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步退一(yi)(yi)步的行(xing)進(jin)(jin)方式(shi)(shi),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在中層(ceng)(ceng)(ceng)既充(chong)分吸(xi)(xi)收(shou)內層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的熱量(liang),又吸(xi)(xi)收(shou)中層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的熱量(liang),同時(shi)又延(yan)長了干(gan)燥(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在此(ci)(ci)達到(dao)干(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至中層(ceng)(ceng)(ceng)另一(yi)(yi)端而落(luo)入(ru)外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內呈(cheng)矩(ju)形多回路方式(shi)(shi)行(xing)進(jin)(jin),達到(dao)干(gan)燥(zao)效果(guo)的物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在熱風作用下(xia)快(kuai)速(su)行(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達到(dao)干(gan)燥(zao)效果(guo)的濕物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因(yin)自重(zhong)而不(bu)能快(kuai)速(su)行(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在此(ci)(ci)矩(ju)形抄(chao)板內進(jin)(jin)行(xing)充(chong)分干(gan)燥(zao),由(you)此(ci)(ci)完成干(gan)燥(zao)目的。
