產品結構
大型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(ji)筒(tong)體部分由三個同(tong)軸水平(ping)放置的(de)(de)內、中(zhong)、外筒(tong)套疊組(zu)成,這(zhe)就使筒(tong)體的(de)(de)截面(mian)(mian)得到充(chong)分的(de)(de)利(li)用。其筒(tong)體外形總長度約(yue)為與之(zhi)相當的(de)(de)單(dan)筒(tong)的(de)(de)30-35%。從而大幅度地減少占地面(mian)(mian)積(ji)和廠房建筑面(mian)(mian)積(ji)。
該(gai)機(ji)的支承裝置,是在外(wai)筒上輪帶(dai)與托輪支承,由電機(ji)直接(jie)帶(dai)動托輪。通(tong)過(guo)托輪與輪帶(dai)摩擦,使筒體轉動。該(gai)機(ji)總體結構緊湊、合理、簡單,為便于(yu)磨損(sun)件(jian)的檢(jian)修更換,在中間(jian)設計(ji)成(cheng)軸向剖分式,用螺栓固定連接(jie)。
工作原(yuan)理(li)
物(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進(jin)(jin)(jin)(jin)入回轉滾(gun)筒(tong)的(de)內(nei)(nei)層(ceng)(ceng),實現順流烘(hong)干(gan),物(wu)料(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)的(de)抄(chao)板(ban)下不斷抄(chao)起、散落呈(cheng)(cheng)螺旋行(xing)進(jin)(jin)(jin)(jin)式實現熱交換,物(wu)料(liao)(liao)移動至(zhi)內(nei)(nei)層(ceng)(ceng)的(de)另一(yi)端(duan)進(jin)(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)逆(ni)流烘(hong)干(gan),物(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)不斷地(di)被反復揚(yang)進(jin)(jin)(jin)(jin),呈(cheng)(cheng)進(jin)(jin)(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)行(xing)進(jin)(jin)(jin)(jin)方(fang)(fang)式,物(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)既充分吸(xi)收(shou)內(nei)(nei)層(ceng)(ceng)滾(gun)筒(tong)散發的(de)熱量,又吸(xi)收(shou)中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)熱量,同時(shi)又延長了干(gan)燥(zao)(zao)(zao)時(shi)間,物(wu)料(liao)(liao)在(zai)(zai)此達到干(gan)燥(zao)(zao)(zao)狀態(tai)。物(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)另一(yi)端(duan)而落入外(wai)層(ceng)(ceng),物(wu)料(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)呈(cheng)(cheng)矩形(xing)多回路(lu)方(fang)(fang)式行(xing)進(jin)(jin)(jin)(jin),達到干(gan)燥(zao)(zao)(zao)效果的(de)物(wu)料(liao)(liao)在(zai)(zai)熱風作(zuo)用下快速(su)行(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒(tong),沒有達到干(gan)燥(zao)(zao)(zao)效果的(de)濕物(wu)料(liao)(liao)因自重而不能快速(su)行(xing)進(jin)(jin)(jin)(jin),物(wu)料(liao)(liao)在(zai)(zai)此矩形(xing)抄(chao)板(ban)內(nei)(nei)進(jin)(jin)(jin)(jin)行(xing)充分干(gan)燥(zao)(zao)(zao),由此完成干(gan)燥(zao)(zao)(zao)目的(de)。
