產品(pin)概況
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產(chan)品結(jie)構(gou)
三筒(tong)(tong)式烘(hong)(hong)(hong)干(gan)機(ji)是通(tong)過對單(dan)筒(tong)(tong)烘(hong)(hong)(hong)干(gan)機(ji)的(de)單(dan)筒(tong)(tong)體(ti)改為套(tao)疊在一起的(de)三筒(tong)(tong)，以(yi)縮(suo)短烘(hong)(hong)(hong)干(gan)機(ji)體(ti)的(de)外形尺寸。該機(ji)工(gong)作時，物料(liao)和熱氣(qi)流依次進入(ru)內至外筒(tong)(tong)體(ti)，在機(ji)體(ti)Z形往復折流后，充分利用(yong)熱能烘(hong)(hong)(hong)干(gan)物料(liao)后再卸出。
烘干機筒體部分由三個(ge)同軸水(shui)平放置的(de)(de)內、中、外筒套疊組成(cheng)，這就使筒體的(de)(de)截面得(de)到充分的(de)(de)利(li)用。其筒體外形總長度(du)約為與(yu)之相當的(de)(de)單筒的(de)(de)30-35%。從而(er)大幅度(du)地減(jian)少(shao)占地面積和(he)廠房建筑面積。
該(gai)機的支承裝置(zhi)，是(shi)在外筒(tong)(tong)上輪帶與托輪支承，由電機直接帶動(dong)托輪。通過(guo)托輪與輪帶摩擦(ca)，使(shi)筒(tong)(tong)體(ti)轉動(dong)。該(gai)機總(zong)體(ti)結構緊湊(cou)、合理、簡單，為便于磨損件的檢修更換，在中間設計成軸向剖分式，用螺栓固(gu)定連接。
工作原理(li)
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)入(ru)(ru)回轉滾筒(tong)的內(nei)層(ceng)(ceng)(ceng),實(shi)現(xian)順流(liu)烘干(gan),物(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的抄(chao)(chao)板(ban)下不(bu)斷(duan)(duan)抄(chao)(chao)起、散(san)落(luo)呈(cheng)(cheng)螺(luo)旋(xuan)行(xing)(xing)進(jin)(jin)(jin)式實(shi)現(xian)熱(re)交(jiao)換，物(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的另一端進(jin)(jin)(jin)入(ru)(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)(xing)逆流(liu)烘干(gan)，物(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)(duan)地被反復揚進(jin)(jin)(jin)，呈(cheng)(cheng)進(jin)(jin)(jin)兩步退一步的行(xing)(xing)進(jin)(jin)(jin)方(fang)式，物(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分(fen)吸收內(nei)層(ceng)(ceng)(ceng)滾筒(tong)散(san)發的熱(re)量(liang)，又吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒(tong)的熱(re)量(liang)，同時又延長了干(gan)燥時間，物(wu)(wu)料(liao)(liao)在(zai)此達到干(gan)燥狀態。物(wu)(wu)料(liao)(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另一端而落(luo)入(ru)(ru)外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾筒(tong)內(nei)呈(cheng)(cheng)矩形多回路方(fang)式行(xing)(xing)進(jin)(jin)(jin)，達到干(gan)燥效果的物(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用下快速(su)行(xing)(xing)進(jin)(jin)(jin)排出滾筒(tong)，沒有達到干(gan)燥效果的濕物(wu)(wu)料(liao)(liao)因自重而不(bu)能快速(su)行(xing)(xing)進(jin)(jin)(jin)，物(wu)(wu)料(liao)(liao)在(zai)此矩形抄(chao)(chao)板(ban)內(nei)進(jin)(jin)(jin)行(xing)(xing)充分(fen)干(gan)燥，由此完成干(gan)燥目的。
