弛張篩介紹
弛張篩是我廠生產的一種新型篩分機械。該機采用雙質體亞共振原理,通過傾斜篩箱上安裝的彈性篩面的弛、張運動拋擲物料的篩分機。其主要特點是篩分效率提高,處理量大,動負荷小,功耗少,噪聲低,因此應用較為廣泛。在這個過程中,彈性聚氨酯篩面以每分鐘800次的頻率連續不斷地擴張、收縮,從而獲得很高的加速度(50g),有效地防止了篩孔堵塞。
使用優勢
1、由于篩(shai)面做弛張運動能夠傳遞給物(wu)料50G的(de)加速(su)度,所以能夠篩(shai)分難篩(shai)物(wu)料,篩(shai)孔不容(rong)易堵塞。
2、將香蕉篩(shai)(shai)(shai)(shai)(shai)和弛(chi)張篩(shai)(shai)(shai)(shai)(shai)的各自優點有機地(di)融合在一起。入料端(duan)物(wu)料速度(du)快、料層薄(bo),大量(liang)(liang)物(wu)料透(tou)(tou)篩(shai)(shai)(shai)(shai)(shai),處理量(liang)(liang)高(gao)。排料端(duan)篩(shai)(shai)(shai)(shai)(shai)面傾角低,物(wu)料速度(du)慢,這得以(yi)將剩(sheng)余的篩(shai)(shai)(shai)(shai)(shai)下物(wu)徹底(di)透(tou)(tou)篩(shai)(shai)(shai)(shai)(shai),達到非常高(gao)的篩(shai)(shai)(shai)(shai)(shai)分效率。
3、線性運動的(de)箱式激振器可靠(kao)性高、維護簡(jian)單。
4、弛張篩(shai)的(de)(de)聚氨(an)酯篩(shai)板是通泰機(ji)械公司特殊設計的(de)(de),以(yi)承受50g的(de)(de)振動(dong)強(qiang)度(du)以(yi)及每(mei)分鐘800次(ci)的(de)(de)曲張,篩(shai)板使用壽命長、篩(shai)機(ji)坐落在空心的(de)(de)橡膠(jiao)彈簧上,產生的(de)(de)噪(zao)音小(xiao),而且橡膠(jiao)彈簧壽命長。篩(shai)機(ji)和支撐結構承受的(de)(de)載(zai)荷比(bi)傳統的(de)(de)弛張篩(shai)小(xiao)得多(盡(jin)管弛張篩(shai)能(neng)產生50g的(de)(de)振動(dong)強(qiang)度(du),遠大于(yu)傳統篩(shai)機(ji)的(de)(de)5g)。
5、篩分(fen)機側部(bu)“U”形設計以形成密封,側板(ban)無磨損(sun),而且防(fang)止了篩上物進入篩下、篩板(ban)用楔形橡膠條固定,不需(xu)要任何螺栓,拆裝方便、快捷、篩分(fen)機轉(zhuan)動(dong)部(bu)件少,運行可(ke)靠性高(gao),日常維護工(gong)作量少,利用率(lv)高(gao)、浮動(dong)篩框振(zhen)幅可(ke)調(diao)馳張(zhang)篩技術參數(shu):
弛張篩工作原理
弛(chi)(chi)張篩(shai)(shai)(shai)(shai)是(shi)雙質(zhi)量振動(dong)(dong)(dong)系(xi)統,采用聚(ju)氨酚橡膠篩(shai)(shai)(shai)(shai)面(mian),支承篩(shai)(shai)(shai)(shai)面(mian)的(de)(de)任意(yi)兩根相(xiang)鄰橫梁都(dou)分別屬(shu)于兩個振動(dong)(dong)(dong)質(zhi)體(ti)(ti),其中一個質(zhi)體(ti)(ti)是(shi)篩(shai)(shai)(shai)(shai)箱,另一個質(zhi)體(ti)(ti)是(shi)配重。在工(gong)作時(shi)(shi)(shi),篩(shai)(shai)(shai)(shai)網(wang)交替地(di)拉(la)緊(jin)和松弛(chi)(chi),使(shi)物(wu)料產生(sheng)前進彈(dan)跳運(yun)動(dong)(dong)(dong),可避免物(wu)料黏附篩(shai)(shai)(shai)(shai)網(wang)并(bing)(bing)堵塞(sai)篩(shai)(shai)(shai)(shai)孔。當(dang)兩質(zhi)體(ti)(ti)相(xiang)差二相(xiang)位振動(dong)(dong)(dong)時(shi)(shi)(shi),任意(yi)兩根相(xiang)鄰橫梁時(shi)(shi)(shi)而(er)靠近,時(shi)(shi)(shi)而(er)遠離,彈(dan)性篩(shai)(shai)(shai)(shai)面(mian)也相(xiang)應時(shi)(shi)(shi)而(er)松弛(chi)(chi),時(shi)(shi)(shi)而(er)張緊(jin),即篩(shai)(shai)(shai)(shai)面(mian)隨篩(shai)(shai)(shai)(shai)箱作牽連運(yun)動(dong)(dong)(dong)的(de)(de)同時(shi)(shi)(shi),還(huan)相(xiang)對篩(shai)(shai)(shai)(shai)箱作相(xiang)對運(yun)動(dong)(dong)(dong)。這種弛(chi)(chi)張運(yun)動(dong)(dong)(dong)不僅使(shi)篩(shai)(shai)(shai)(shai)孔不斷產生(sheng)變形(xing),而(er)且(qie)大(da)(da)大(da)(da)增(zeng)加了(le)篩(shai)(shai)(shai)(shai)面(mian)的(de)(de)振動(dong)(dong)(dong)強(qiang)(qiang)度,從而(er)有(you)效(xiao)地(di)克服(fu)了(le)篩(shai)(shai)(shai)(shai)孔堵塞(sai)現象,顯著提(ti)高了(le)篩(shai)(shai)(shai)(shai)機處理能(neng)力(li)。但是(shi)因(yin)篩(shai)(shai)(shai)(shai)箱的(de)(de)振動(dong)(dong)(dong)強(qiang)(qiang)度并(bing)(bing)不大(da)(da),故(gu)機械強(qiang)(qiang)度容易保證,但篩(shai)(shai)(shai)(shai)面(mian)的(de)(de)振動(dong)(dong)(dong)強(qiang)(qiang)度較大(da)(da)且(qie)反復變形(xing),故(gu)篩(shai)(shai)(shai)(shai)面(mian)壽(shou)命(ming)較低。

與振動篩區別
第一,振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)原理不同:普(pu)通的振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)只是由(you)于激振(zhen)(zhen)(zhen)(zhen)(zhen)器(qi)產(chan)生(sheng)圓振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)或線性振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong),篩(shai)(shai)面(mian)與振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)是一體振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong);而弛張(zhang)篩(shai)(shai)的振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)是由(you)兩局部組(zu)成,由(you)激振(zhen)(zhen)(zhen)(zhen)(zhen)器(qi)產(chan)生(sheng)圓振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)或線性振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)以及浮動(dong)(dong)(dong)篩(shai)(shai)框產(chan)生(sheng)的篩(shai)(shai)面(mian)馳張(zhang)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong),這樣能夠保(bao)證篩(shai)(shai)孔不易梗塞。
第二:弛張篩(shai)篩(shai)分物(wu)料振(zhen)(zhen)(zhen)動強度(du)大(da),由于雙重(zhong)振(zhen)(zhen)(zhen)動原理可(ke)使篩(shai)分物(wu)料產生50g的振(zhen)(zhen)(zhen)動強度(du),而普(pu)通振(zhen)(zhen)(zhen)動篩(shai)只能(neng)到達(da)5g的振(zhen)(zhen)(zhen)動強度(du),所(suo)以弛張篩(shai)能(neng)到達(da)很高的篩(shai)分效率。
第三:弛張篩(shai)篩(shai)分物料(liao)的(de)順應性強(qiang),能處置(zhi)濕(shi)粘的(de)難篩(shai)物料(liao),且不梗(geng)塞篩(shai)孔。
第四:由于振(zhen)動(dong)原理的(de)(de)先進性,整體的(de)(de)弛張篩質量(liang)輕,選用驅動(dong)電機功率低。
第五:設(she)備(bei)(bei)維(wei)護運轉(zhuan)費用(yong)(yong)低,由(you)于弛張篩(shai)采用(yong)(yong)原(yuan)裝整體進(jin)口,比普(pu)通振(zhen)動篩(shai)設(she)備(bei)(bei)的運轉(zhuan)平安系數高,同時設(she)備(bei)(bei)自身轉(zhuan)動部件少(shao),維(wei)護工作量少(shao),維(wei)修便當簡單(dan)、費用(yong)(yong)低。
