立(li)友超聲波振動篩在電池材(cai)料篩分(fen)中的應用(yong)
電(dian)(dian)(dian)池(chi)材(cai)(cai)(cai)料(liao)(liao)(liao)用于鋰(li)電(dian)(dian)(dian)池(chi),鎳鎘(ge)電(dian)(dian)(dian)池(chi)、鎳氫(qing)電(dian)(dian)(dian)池(chi),鋰(li)電(dian)(dian)(dian)池(chi)現在(zai)通用的材(cai)(cai)(cai)料(liao)(liao)(liao)是鈷(gu)酸鋰(li)(LiCoO2),它(ta)具有很高(gao)的比(bi)能(neng)量,放電(dian)(dian)(dian)電(dian)(dian)(dian)壓比(bi)較平坦,使用溫度(du)廣(guang)泛。電(dian)(dian)(dian)池(chi)材(cai)(cai)(cai)料(liao)(liao)(liao)主要有石墨(mo)化(hua)(hua)碳材(cai)(cai)(cai)料(liao)(liao)(liao)、無(wu)定形碳材(cai)(cai)(cai)料(liao)(liao)(liao)、氮化(hua)(hua)物、硅(gui)基(ji)材(cai)(cai)(cai)料(liao)(liao)(liao)、錫(xi)基(ji)材(cai)(cai)(cai)料(liao)(liao)(liao)、新型(xing)合(he)金和其它(ta)材(cai)(cai)(cai)料(liao)(liao)(liao)。在(zai)加工中電(dian)(dian)(dian)池(chi)材(cai)(cai)(cai)料(liao)(liao)(liao)微(wei)粉大(da)小不同,要對其進行(xing)分級,使用超聲(sheng)波振動篩進行(xing)篩分可以解(jie)決強(qiang)吸附性、易團聚、高(gao)靜電(dian)(dian)(dian)、高(gao)精細、高(gao)密度(du)、輕比(bi)重等(deng)篩分難題。
超(chao)聲波(bo)振(zhen)(zhen)(zhen)動篩(shai)電源產(chan)生的高(gao)(gao)頻(pin)電通過(guo)換能器(qi)(qi)(qi)轉換成高(gao)(gao)頻(pin)正(zheng)弦形成的縱向振(zhen)(zhen)(zhen)蕩(dang)波(bo),這(zhe)些振(zhen)(zhen)(zhen)蕩(dang)波(bo)傳(chuan)(chuan)到共(gong)振(zhen)(zhen)(zhen)器(qi)(qi)(qi)上(shang)(shang)使(shi)共(gong)振(zhen)(zhen)(zhen)器(qi)(qi)(qi)產(chan)生共(gong)振(zhen)(zhen)(zhen),這(zhe)些振(zhen)(zhen)(zhen)蕩(dang)波(bo)傳(chuan)(chuan)到共(gong)振(zhen)(zhen)(zhen)器(qi)(qi)(qi)上(shang)(shang)使(shi)共(gong)振(zhen)(zhen)(zhen)器(qi)(qi)(qi)產(chan)生共(gong)振(zhen)(zhen)(zhen),然(ran)后由共(gong)振(zhen)(zhen)(zhen)器(qi)(qi)(qi)將振(zhen)(zhen)(zhen)動均勻傳(chuan)(chuan)輸至篩(shai)面。篩(shai)網(wang)上(shang)(shang)的物料在做低頻(pin)三次元(yuan)振(zhen)(zhen)(zhen)動的同時,疊加上(shang)(shang)超(chao)聲波(bo)振(zhen)(zhen)(zhen)動,既可防止網(wang)孔堵塞(sai),又可提(ti)高(gao)(gao)篩(shai)分產(chan)量和(he)精度。
電池材(cai)料(liao)篩(shai)(shai)分(fen)(fen)(fen)使用(yong)超(chao)聲(sheng)波振動(dong)(dong)篩(shai)(shai)的(de)(de)特點:1.在達到高(gao)精度(du)(du)、高(gao)網目(mu)(mu)篩(shai)(shai)分(fen)(fen)(fen)的(de)(de)同時,控制較窄(zhai)的(de)(de)粒度(du)(du)范(fan)圍。2.可單層與多層使用(yong),一套智能超(chao)聲(sheng)波發生器同時使用(yong)三個換(huan)能器。3.的(de)(de)篩(shai)(shai)網自潔功(gong)能:大于500目(mu)(mu)篩(shai)(shai)分(fen)(fen)(fen),無網孔(kong)堵塞,無篩(shai)(shai)分(fen)(fen)(fen)效率(lv)衰減。4.真正解決強吸附性(xing)、易團聚、高(gao)靜電、高(gao)精細(xi)、高(gao)密度(du)(du)、輕比重等(deng)篩(shai)(shai)分(fen)(fen)(fen)難題。5.保證所處理物料(liao)的(de)(de)特性(xing)不變。6.不產(chan)生彈跳(tiao)球等(deng)輔助物對(dui)粉體的(de)(de)污(wu)染;7.篩(shai)(shai)分(fen)(fen)(fen)精度(du)(du)比普通振動(dong)(dong)篩(shai)(shai)可提高(gao)1—70%,產(chan)量可提高(gao)0.5-10倍。
