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)體部(bu)分(fen)由(you)三個同軸水(shui)平(ping)放置(zhi)的(de)內、中、外(wai)筒(tong)套疊組成,這就使(shi)筒(tong)體的(de)截面得到(dao)充分(fen)的(de)利用。其筒(tong)體外(wai)形總長度約為與(yu)之相當的(de)單筒(tong)的(de)30-35%。從而大幅度地減少(shao)占地面積和(he)廠房建筑(zhu)面積。
該(gai)機的(de)支承裝置,是在外筒上輪(lun)帶與(yu)托(tuo)輪(lun)支承,由電機直接帶動托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶摩擦(ca),使筒體轉動。該(gai)機總體結構緊湊、合理、簡單,為便于磨(mo)損(sun)件的(de)檢(jian)修(xiu)更換,在中間設計成軸向(xiang)剖分式,用螺栓固定連接。
工(gong)作原理
物(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)入(ru)回轉滾(gun)筒(tong)(tong)(tong)的(de)(de)(de)(de)內層(ceng)(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan),物(wu)料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)抄(chao)板下(xia)不斷抄(chao)起、散落(luo)呈螺旋行(xing)進(jin)式(shi)實現熱交換,物(wu)料(liao)(liao)(liao)移動至(zhi)內層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)另一(yi)端(duan)進(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)逆流烘干(gan),物(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)不斷地被反復(fu)揚進(jin),呈進(jin)兩步(bu)退一(yi)步(bu)的(de)(de)(de)(de)行(xing)進(jin)方式(shi),物(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)既充(chong)分吸(xi)收內層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)散發(fa)的(de)(de)(de)(de)熱量,又(you)吸(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)的(de)(de)(de)(de)熱量,同時又(you)延(yan)長(chang)了干(gan)燥(zao)(zao)時間,物(wu)料(liao)(liao)(liao)在(zai)(zai)此達到干(gan)燥(zao)(zao)狀(zhuang)態。物(wu)料(liao)(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)而落(luo)入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)內呈矩(ju)形(xing)多(duo)回路方式(shi)行(xing)進(jin),達到干(gan)燥(zao)(zao)效果的(de)(de)(de)(de)物(wu)料(liao)(liao)(liao)在(zai)(zai)熱風作用(yong)下(xia)快(kuai)速行(xing)進(jin)排出滾(gun)筒(tong)(tong)(tong),沒(mei)有達到干(gan)燥(zao)(zao)效果的(de)(de)(de)(de)濕物(wu)料(liao)(liao)(liao)因自重(zhong)而不能快(kuai)速行(xing)進(jin),物(wu)料(liao)(liao)(liao)在(zai)(zai)此矩(ju)形(xing)抄(chao)板內進(jin)行(xing)充(chong)分干(gan)燥(zao)(zao),由此完成干(gan)燥(zao)(zao)目的(de)(de)(de)(de)。
