具有(you)圓(yuan)形軌(gui)跡的慣(guan)(guan)性(xing)振(zhen)(zhen)(zhen)動篩(shai)為圓(yuan)振(zhen)(zhen)(zhen)動篩(shai),簡稱圓(yuan)振(zhen)(zhen)(zhen)篩(shai)。這(zhe)種慣(guan)(guan)性(xing)振(zhen)(zhen)(zhen)動篩(shai)又稱單軸振(zhen)(zhen)(zhen)動篩(shai)圓(yuan)形軌(gui)跡慣(guan)(guan)性(xing)振(zhen)(zhen)(zhen)動篩(shai)可用于各種篩(shai)分作業。由(you)于篩(shai)面的圓(yuan)形振(zhen)(zhen)(zhen)動軌(gui)跡,使篩(shai)面上的物料不斷地翻轉和松散,因而(er)圓(yuan)振(zhen)(zhen)(zhen)篩(shai)有(you)以下(xia)特(te)點:
1.細粒級有機會(hui)向料層下部移(yi)動,并(bing)通過篩孔排出;
2.卡在篩孔中的物料可以跳(tiao)出,防(fang)止(zhi)篩孔堵塞:
3.篩分效率較高;
4.可以(yi)變化篩(shai)(shai)面傾角,從而改變物料沿(yan)篩(shai)(shai)面的運動速(su)度(du),提高篩(shai)(shai)子的處理量;
5.對于難篩(shai)物(wu)料(liao)可以(yi)使主(zhu)軸反翻(fan),從(cong)而使振(zhen)動(dong)方向同(tong)物(wu)料(liao)運動(dong)方向相反,物(wu)料(liao)沿篩(shai)面(mian)運動(dong)速度降(jiang)低(在篩(shai)面(mian)傾角(jiao)與主(zhu)軸轉速相同(tong)的情況下),以(yi)提(ti)高篩(shai)分效率。
圓振篩安裝
(1)圓振(zhen)篩(shai)在安(an)裝(zhuang)前,首先(xian)按(an)照裝(zhuang)箱單檢查零(ling)部件是否齊全和損壞(huai),其(qi)中(zhong)振(zhen)動(dong)器自出廠日起(qi),若超過(guo)六(liu)個月時,必(bi)須(xu)重(zhong)新拆(chai)洗和組裝(zhuang),并換上清潔的潤滑油。
(2)按(an)照圓(yuan)振篩安(an)裝圖(tu)進行設備安(an)裝,其(qi)中支承底架必(bi)須水平安(an)裝在基礎(chu)上,基礎(chu)應(ying)有足夠的剛度和(he)(he)強度,以(yi)支承振動篩的全(quan)部動負荷(he)和(he)(he)靜負荷(he)。
(3)篩箱四角有(you)吊(diao)(diao)耳(er),支承底架(jia)四角有(you)起吊(diao)(diao)孔,按(an)圖要求(qiu)進行吊(diao)(diao)運(yun),不可直接掛(gua)在振(zhen)動器上吊(diao)(diao)運(yun)整(zheng)個篩子。
(4)確(que)保(bao)篩箱與料(liao)斗、料(liao)槽(溜槽)等一類非運動件之間(jian)應(ying)保(bao)持(chi)最小75m的間(jian)隙。
(5)確保(bao)彈簧座與(yu)篩(shai)箱上摩擦阻尼板之(zhi)間有10mm間隙。
(6)減振彈(dan)簧(huang)按自由高度進行選配,分(fen)別使前端(duan)或者后端(duan)的左(zuo)右兩側彈(dan)簧(huang)自由高度盡量相等,誤差不超(chao)過5m。篩箱安裝后,篩面左(zuo)右保持水平(ping),否(fou)則(ze),可在彈(dan)簧(huang)座與(yu)支承件問墊薄鐵片。
