二手雙滾筒干燥機供應

二手雙滾(gun)(gun)筒干燥(zao)(zao)機(ji)是(shi)指干燥(zao)(zao)機(ji)由(you)兩(liang)只滾(gun)(gun)筒同(tong)時完成干燥(zao)(zao)操作(zuo)的機(ji)械，干燥(zao)(zao)機(ji)的兩(liang)個滾(gun)(gun)筒由(you)同(tong)一(yi)套減(jian)速傳(chuan)動裝置(zhi)，經相(xiang)(xiang)同(tong)模(mo)數和(he)齒數的一(yi)對(dui)齒輪嚙合，使(shi)兩(liang)組相(xiang)(xiang)同(tong)直(zhi)徑的滾(gun)(gun)筒相(xiang)(xiang)對(dui)轉動而操作(zuo)的。雙滾(gun)(gun)筒干燥(zao)(zao)機(ji)按布料位置(zhi)的不同(tong)，可以(yi)分為對(dui)滾(gun)(gun)式(shi)和(he)同(tong)槽式(shi)兩(liang)類。

對滾(gun)式雙滾(gun)筒(tong)(tong)(tong)干燥機，料液(ye)存在(zai)(zai)兩滾(gun)筒(tong)(tong)(tong)中部(bu)的(de)(de)(de)凹槽(cao)區域(yu)內，四(si)周設有(you)堰板擋料。兩筒(tong)(tong)(tong)的(de)(de)(de)間(jian)(jian)隙，由一對節圓直徑與筒(tong)(tong)(tong)體外徑*或相近的(de)(de)(de)嚙(nie)合輪控制，一般在(zai)(zai)0.5～lmm范圍，不(bu)允許料液(ye)泄漏。對滾(gun)的(de)(de)(de)轉(zhuan)動(dong)方向，可根據料液(ye)的(de)(de)(de)實際和裝置(zhi)(zhi)布置(zhi)(zhi)的(de)(de)(de)要(yao)求(qiu)確定。滾(gun)筒(tong)(tong)(tong)轉(zhuan)動(dong)時咬(yao)入(ru)(ru)角位于料液(ye)端時，料膜(mo)的(de)(de)(de)厚度(du)(du)由兩筒(tong)(tong)(tong)之間(jian)(jian)的(de)(de)(de)空(kong)隙控制。咬(yao)入(ru)(ru)角若(ruo)處于反向時，兩筒(tong)(tong)(tong)之間(jian)(jian)的(de)(de)(de)料膜(mo)厚度(du)(du)，由設置(zhi)(zhi)在(zai)(zai)筒(tong)(tong)(tong)體長度(du)(du)方向上的(de)(de)(de)堰板與筒(tong)(tong)(tong)體之間(jian)(jian)的(de)(de)(de)間(jian)(jian)隙控制。該形式的(de)(de)(de)干燥器，適用于有(you)沉淀(dian)的(de)(de)(de)漿狀(zhuang)物(wu)料或粘度(du)(du)大物(wu)料的(de)(de)(de)干燥。

二手雙滾筒干燥機供應

同槽式雙滾筒(tong)(tong)干燥(zao)機。它的(de)兩(liang)組滾筒(tong)(tong)之間的(de)間隙較(jiao)大(da)，相對(dui)嚙合的(de)齒輪(lun)的(de)節圓直徑大(da)于筒(tong)(tong)體外徑。上(shang)料(liao)(liao)時，兩(liang)筒(tong)(tong)在同一料(liao)(liao)槽中浸(jin)液(ye)(ye)布膜，相對(dui)轉(zhuan)動，互不干擾(rao)。適用于溶液(ye)(ye)、乳(ru)濁液(ye)(ye)等物料(liao)(liao)干燥(zao)。

二(er)手(shou)雙(shuang)滾(gun)筒(tong)(tong)(tong)(tong)干(gan)燥(zao)(zao)機(ji)的(de)滾(gun)筒(tong)(tong)(tong)(tong)直徑一(yi)般為0.5～2m；長(chang)徑比（L/D）=1.5～2。轉速(su)、滾(gun)筒(tong)(tong)(tong)(tong)內蒸汽壓力等操作(zuo)條件與單滾(gun)筒(tong)(tong)(tong)(tong)干(gan)燥(zao)(zao)機(ji)的(de)設計相同(tong)，但傳動功率為單滾(gun)筒(tong)(tong)(tong)(tong)的(de)2倍左(zuo)右。雙(shuang)滾(gun)筒(tong)(tong)(tong)(tong)式(shi)干(gan)燥(zao)(zao)機(ji)的(de)進料(liao)(liao)(liao)方式(shi)與單滾(gun)筒(tong)(tong)(tong)(tong)干(gan)燥(zao)(zao)機(ji)有所不(bu)同(tong)，若(ruo)為上部進料(liao)(liao)(liao)，由料(liao)(liao)(liao)堰控制料(liao)(liao)(liao)膜的(de)厚度的(de)兩(liang)滾(gun)筒(tong)(tong)(tong)(tong)干(gan)燥(zao)(zao)器(qi)，可在(zai)干(gan)燥(zao)(zao)器(qi)底部的(de)中(zhong)間位置(zhi)，設置(zhi)一(yi)臺螺旋輸送器(qi)機(ji)，集中(zhong)出料(liao)(liao)(liao)。下部進料(liao)(liao)(liao)的(de)對滾(gun)式(shi)雙(shuang)滾(gun)筒(tong)(tong)(tong)(tong)干(gan)燥(zao)(zao)機(ji)，則分(fen)別在(zai)兩(liang)組滾(gun)筒(tong)(tong)(tong)(tong)的(de)側面單獨(du)設置(zhi)出料(liao)(liao)(liao)裝置(zhi)。
