產品結構(gou)
三筒(tong)烘干(gan)機(ji)是通過(guo)對單筒(tong)烘干(gan)機(ji)的單筒(tong)體(ti)改為(wei)套(tao)疊(die)在一起(qi)的三筒(tong),以縮短烘干(gan)機(ji)體(ti)的外形(xing)尺寸(cun)。該機(ji)工作時(shi),物料(liao)和熱氣流依次進入內至外筒(tong)體(ti),在機(ji)體(ti)Z形(xing)往(wang)復折流后,充分利用熱能烘干(gan)物料(liao)后再(zai)卸出。
烘(hong)干機筒(tong)體部(bu)分由(you)三個同(tong)軸水平(ping)放置的(de)(de)內、中、外筒(tong)套疊組成,這就(jiu)使筒(tong)體的(de)(de)截面(mian)得到充分的(de)(de)利用。其筒(tong)體外形總(zong)長度(du)約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度(du)地減少(shao)占(zhan)地面(mian)積(ji)和(he)廠房(fang)建(jian)筑面(mian)積(ji)。
該機的(de)支承裝(zhuang)置,是在(zai)(zai)外筒(tong)上輪(lun)帶與(yu)托(tuo)(tuo)輪(lun)支承,由電(dian)機直接帶動(dong)托(tuo)(tuo)輪(lun)。通過(guo)托(tuo)(tuo)輪(lun)與(yu)輪(lun)帶摩(mo)擦,使筒(tong)體(ti)轉動(dong)。該機總體(ti)結構緊湊(cou)、合理(li)、簡(jian)單,為便(bian)于磨損(sun)件的(de)檢(jian)修更換(huan),在(zai)(zai)中間設(she)計成(cheng)軸(zhou)向(xiang)剖分式,用螺栓固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)(jin)入(ru)(ru)回(hui)轉滾筒的(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng),實現順流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下不斷抄(chao)起、散(san)(san)落(luo)呈螺旋行(xing)進(jin)(jin)式(shi)實現熱交換,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動(dong)至內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)另(ling)一(yi)端進(jin)(jin)入(ru)(ru)中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)逆流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)不斷地被反(fan)復揚進(jin)(jin),呈進(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)(de)行(xing)進(jin)(jin)方式(shi),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)既(ji)充分(fen)吸(xi)收內(nei)(nei)層(ceng)(ceng)(ceng)滾筒散(san)(san)發的(de)(de)熱量,又(you)吸(xi)收中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒的(de)(de)熱量,同(tong)時(shi)(shi)又(you)延長了干(gan)燥(zao)時(shi)(shi)間,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此達到干(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一(yi)端而(er)落(luo)入(ru)(ru)外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)滾筒內(nei)(nei)呈矩形(xing)多(duo)回(hui)路方式(shi)行(xing)進(jin)(jin),達到干(gan)燥(zao)效果的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在熱風作用(yong)下快速(su)行(xing)進(jin)(jin)排(pai)出滾筒,沒(mei)有達到干(gan)燥(zao)效果的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因(yin)自重而(er)不能快速(su)行(xing)進(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此矩形(xing)抄(chao)板內(nei)(nei)進(jin)(jin)行(xing)充分(fen)干(gan)燥(zao),由此完成干(gan)燥(zao)目的(de)(de)。
