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(hong)干機筒(tong)(tong)體部分由(you)三個(ge)同軸水平放置(zhi)的內、中、外筒(tong)(tong)套疊組成，這就使筒(tong)(tong)體的截面(mian)得到充分的利用。其筒(tong)(tong)體外形(xing)總長度約為(wei)與之(zhi)相當的單筒(tong)(tong)的30-35%。從而大幅度地減少占地面(mian)積和廠房建筑面(mian)積。
該(gai)機的支承裝置(zhi)，是在外(wai)筒上輪(lun)(lun)帶與(yu)托(tuo)輪(lun)(lun)支承，由電機直(zhi)接(jie)帶動(dong)托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦(ca)，使筒體轉動(dong)。該(gai)機總體結(jie)構緊湊、合理、簡單，為便于磨(mo)損件(jian)的檢(jian)修更(geng)換，在中(zhong)間(jian)設計(ji)成軸向剖(pou)分(fen)式，用螺(luo)栓(shuan)固定連接(jie)。
工作(zuo)原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)(jin)入(ru)回轉滾(gun)筒的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現順(shun)流烘(hong)干,物(wu)(wu)(wu)料(liao)(liao)(liao)在內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板(ban)(ban)下不(bu)斷抄(chao)起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)式(shi)實現熱(re)交換，物(wu)(wu)(wu)料(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一端進(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)(xing)逆流烘(hong)干，物(wu)(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反(fan)復揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步(bu)退(tui)一步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)(jin)方式(shi)，物(wu)(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充(chong)分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒散發的(de)(de)熱(re)量，又吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒的(de)(de)熱(re)量，同時又延長(chang)了干燥(zao)時間，物(wu)(wu)(wu)料(liao)(liao)(liao)在此達(da)到(dao)干燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一端而(er)落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒內(nei)呈矩形(xing)多回路(lu)方式(shi)行(xing)(xing)進(jin)(jin)(jin)，達(da)到(dao)干燥(zao)效果的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在熱(re)風作用下快(kuai)速(su)行(xing)(xing)進(jin)(jin)(jin)排(pai)出滾(gun)筒，沒有達(da)到(dao)干燥(zao)效果的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自重(zhong)而(er)不(bu)能快(kuai)速(su)行(xing)(xing)進(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)在此矩形(xing)抄(chao)板(ban)(ban)內(nei)進(jin)(jin)(jin)行(xing)(xing)充(chong)分干燥(zao)，由此完成干燥(zao)目(mu)的(de)(de)。
