產品結構
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(tong)(tong)體(ti)(ti)(ti)部分由三個同軸水平放置的(de)內、中(zhong)、外筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體(ti)(ti)(ti)的(de)截(jie)面得(de)到充分的(de)利用。其筒(tong)(tong)體(ti)(ti)(ti)外形總(zong)長(chang)度約為與之(zhi)相當的(de)單(dan)筒(tong)(tong)的(de)30-35%。從而大幅度地(di)減少占地(di)面積和廠房建(jian)筑面積。
該機的支承(cheng)裝置,是在外筒(tong)上(shang)輪(lun)(lun)帶(dai)與托輪(lun)(lun)支承(cheng),由電機直(zhi)接帶(dai)動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使(shi)筒(tong)體轉動。該機總體結構緊(jin)湊、合理、簡單(dan),為(wei)便于磨(mo)損件的檢修更換,在中間設計成(cheng)軸向剖分(fen)式(shi),用螺栓固定連接。
工作原理
物(wu)(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)(jin)(jin)(jin)入(ru)(ru)回轉滾筒(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng),實現(xian)順流(liu)烘干(gan)(gan),物(wu)(wu)(wu)料(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)抄(chao)(chao)板下(xia)不(bu)斷(duan)抄(chao)(chao)起、散落呈(cheng)螺旋行(xing)進(jin)(jin)(jin)(jin)(jin)式實現(xian)熱交換,物(wu)(wu)(wu)料(liao)移動至(zhi)(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)(de)另一(yi)(yi)端進(jin)(jin)(jin)(jin)(jin)入(ru)(ru)中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)(jin)行(xing)逆(ni)流(liu)烘干(gan)(gan),物(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin)(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)(jin)兩(liang)步(bu)退一(yi)(yi)步(bu)的(de)(de)行(xing)進(jin)(jin)(jin)(jin)(jin)方(fang)式,物(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)既充(chong)分吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾筒(tong)散發的(de)(de)熱量(liang),又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)熱量(liang),同時又延長了干(gan)(gan)燥(zao)時間,物(wu)(wu)(wu)料(liao)在(zai)此達到干(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)行(xing)至(zhi)(zhi)中(zhong)層(ceng)(ceng)(ceng)另一(yi)(yi)端而落入(ru)(ru)外(wai)(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)在(zai)外(wai)(wai)層(ceng)(ceng)(ceng)滾筒(tong)內(nei)呈(cheng)矩(ju)形多回路(lu)方(fang)式行(xing)進(jin)(jin)(jin)(jin)(jin),達到干(gan)(gan)燥(zao)效果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)在(zai)熱風(feng)作用下(xia)快(kuai)速行(xing)進(jin)(jin)(jin)(jin)(jin)排出滾筒(tong),沒(mei)有達到干(gan)(gan)燥(zao)效果(guo)的(de)(de)濕物(wu)(wu)(wu)料(liao)因自重(zhong)而不(bu)能快(kuai)速行(xing)進(jin)(jin)(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)在(zai)此矩(ju)形抄(chao)(chao)板內(nei)進(jin)(jin)(jin)(jin)(jin)行(xing)充(chong)分干(gan)(gan)燥(zao),由此完成干(gan)(gan)燥(zao)目(mu)的(de)(de)。
