弛(chi)張振(zhen)動(dong)(dong)(dong)篩(shai)從傳統的(de)(de)圓(yuan)振(zhen)動(dong)(dong)(dong)篩(shai)發展而(er)來(lai),采用基(ji)本振(zhen)動(dong)(dong)(dong)和附加振(zhen)動(dong)(dong)(dong)的(de)(de)雙重振(zhen)動(dong)(dong)(dong)原(yuan)理,基(ji)本振(zhen)動(dong)(dong)(dong)是(shi)(shi)由偏(pian)心塊旋轉產生的(de)(de)圓(yuan)形振(zhen)動(dong)(dong)(dong),附加振(zhen)動(dong)(dong)(dong)是(shi)(shi)基(ji)本振(zhen)動(dong)(dong)(dong)帶動(dong)(dong)(dong)產生的(de)(de)橢圓(yuan)形振(zhen)動(dong)(dong)(dong)。兩個(ge)參振(zhen)質(zhi)量以相(xiang)同的(de)(de)頻(pin)率相(xiang)對振(zhen)動(dong)(dong)(dong),由于篩(shai)面兩端分別安裝在(zai)固定框和浮動(dong)(dong)(dong)框架上(shang),聚氨(an)酯(zhi)篩(shai)面連(lian)續不(bu)(bu)斷的(de)(de)擴張、收縮,從而(er)獲得較高的(de)(de)加速(su)度。兩個(ge)參振(zhen)質(zhi)量相(xiang)對線性運動(dong)(dong)(dong)是(shi)(shi)可調的(de)(de),可以根據篩(shai)分物料不(bu)(bu)同調整所有(you)必要的(de)(de)參數。線性振(zhen)動(dong)(dong)(dong)的(de)(de)固定篩(shai)框和被激勵的(de)(de)浮動(dong)(dong)(dong)篩(shai)框組成了共振(zhen)系統,二者產生相(xiang)對運動(dong)(dong)(dong)。
1、將(jiang)(jiang)香蕉(jiao)篩(shai)和弛張(zhang)篩(shai)的各(ge)自優點(dian)有機地融合(he)在一起。入料(liao)(liao)(liao)端(duan)物(wu)(wu)料(liao)(liao)(liao)速度(du)(du)快、料(liao)(liao)(liao)層薄,大量物(wu)(wu)料(liao)(liao)(liao)透(tou)篩(shai),處理量高(gao)。排料(liao)(liao)(liao)端(duan)篩(shai)面傾角低,物(wu)(wu)料(liao)(liao)(liao)速度(du)(du)慢,這得以(yi)將(jiang)(jiang)剩(sheng)余的篩(shai)下物(wu)(wu)徹底(di)透(tou)篩(shai),達到較高(gao)的篩(shai)分效率,浮動篩(shai)框振(zhen)幅可調;
2、篩面(mian)高頻弛張運動,能夠傳遞給物料50g的加速度,有效解決粘濕物料的篩分,確保篩孔不堵塞(sai);
3、弛(chi)張(zhang)篩(shai)的聚氨酯(zhi)篩(shai)板是(shi)本公(gong)司特殊設計,以(yi)承受(shou)50g的振動強度以(yi)及(ji)每分鐘800次的曲張(zhang),篩(shai)板用(yong)楔形橡膠條固定,不需要任何螺栓,拆裝方便、快捷;
4、可靠性的(de)偏心箱式激振器承載能力大,使用壽命長、維護簡單;
5、篩(shai)(shai)分機側(ce)部“U”形設計以(yi)形成密封,側(ce)板無磨損,而且防止了篩(shai)(shai)上(shang)物進入篩(shai)(shai)下。
