摘 要
振動(dòng)篩的研究不斷地向著標(biāo)準(zhǔn)化、系列化、通用化發(fā)展，并引入現(xiàn)代化設(shè)計(jì)手段，采用新材料、新技術(shù)、新工藝，其目的在于不斷擴(kuò)大篩機(jī)應(yīng)用領(lǐng)域，滿足國民經(jīng)濟(jì)建設(shè)發(fā)展的需要，并擔(dān)當(dāng)對外出口的任務(wù)。
本文所設(shè)計(jì)的振動(dòng)篩的篩分物料為球磨機(jī)產(chǎn)品。該產(chǎn)品的大小不是很平均，為了做出更符合要求的物料就需要用振動(dòng)篩來將球磨機(jī)產(chǎn)品進(jìn)一步細(xì)分，將不符合要求的物料重新用球磨機(jī)磨小。經(jīng)過這樣的反復(fù)處理最終將物料全部做成符合要求的產(chǎn)品。本課題的振動(dòng)篩為自同步雙振動(dòng)電機(jī)驅(qū)動(dòng)的，其特點(diǎn)是結(jié)構(gòu)簡單、安裝方便、成本低、容易操作及維護(hù)等。其篩箱為板梁鉚焊組合結(jié)構(gòu)，由主副側(cè)板、管梁、入料擋板、出料板、篩板等組成，側(cè)板選用低合金壓力容器鋼板，強(qiáng)度高、可焊性好，周邊折彎，并在振動(dòng)方向及沿縱向連接多根角鋼，使側(cè)板剛度大大增強(qiáng)，有利于強(qiáng)度的提高和噪音的降低。管梁由法蘭盤、無縫鋼管、加強(qiáng)槽鋼等組成，重量輕、強(qiáng)度大，便于制造安裝，具有互換性。加強(qiáng)槽鋼上有T形孔，使用T形螺栓，便于篩板的安裝維護(hù)，消除U形螺栓對管梁的磨損。工作原理：兩臺振動(dòng)電機(jī)的型號相同，可以產(chǎn)生一種組合的直線振動(dòng)。這種振動(dòng)可以使輸送槽體中的物料運(yùn)動(dòng)，并與篩面發(fā)生碰撞，使小于篩孔的物料透過，從而實(shí)現(xiàn)物料的幾何分級，實(shí)現(xiàn)篩分?？傮w方案為：采用普通篩分法，振動(dòng)形式為共振，運(yùn)動(dòng)軌跡為直線運(yùn)動(dòng)，激振方式為慣性式，隔振方式為一級隔振，隔振彈簧為金屬螺旋式隔振彈簧。

關(guān)鍵詞：振動(dòng)篩; 篩箱; 振動(dòng)電機(jī)

Abstract
The shaker research unceasingly to the standardization, the seriation, the universalized development, and the introduction modernization design method, uses the new material, the new technology, the new craft, its goal lies in unceasingly expands the sieve machine application domain, satisfies national economy construction the need to develop, and takes on the foreign exportation the duty.
Finally completely makes after such repeatedly processing the materi all tallies the request product. This topic shaker for self-synchronizing pair vibration motor-driven, Its characteristic is the structure simple, the installs convenient, the cost low, is easy to operate and the maintenance and so on. It sieves the box is board crossbeam riveting hitch welds built-up section, By host vice- side bar, Hollow beam, Enters the material back plate, Leaves material board, Sieves board and so on composition, The side bar selects the low-alloy pressure vessel steel plate, The intensity is high, The weldability is good, Peripheral knee bend, And in the vibration direction and along longitudinal connects themulti- roots angle steel, Causes the side bar rigidity big enhancement, Is advantageous to the intensity enhancement and noise reducing. Hollow beam by flange plate, Seamless steel pipe, Strengthens composition and so on channel steel, The weight light, the intensity is big, is advantageous for themanufacture installment, Has the interchangeability. Strengthens in the channel steel to have the T shape hole, Uses the T shape bolt, Is advantageous for screen board installs the maintenance, Eliminates the U shape bolt to the hollow beam attrition. Principle of work: Two vibrate the electrical machinery the model to be same, May have one kind of combination straight-line oscillation. This kind of vibration may cause in the transportation trough body thematerial movement, And has the collision with the screening surface, And has the collision with the screening surface, Thus realization material geometry graduation, Realization screening. The overall plan is: Uses the ordinary screening law, The vibration form for resonates, The path is the translation, Stirs up the strength vibration the way is the inertia type, The vibration isolation way is level of vibration isolations, The vibration isolation spring is the metal screw type vibrationisolation spring。

Keywords:the vibration screen; the box screen; the vibration electric machinery
