工作原理 | Operating principle | |
| 分離的目的是將混合料液中不同質(zhì)量比的物質(zhì)分離出來(lái)：分離形式有固液分離、固固分離、液液分離、固液液分離。 當(dāng)混合料液由進(jìn)料口進(jìn)入高速旋轉(zhuǎn)的轉(zhuǎn)鼓體內(nèi)腔后，混合液體中比重較大的固性物，在離心力加速度的作用下，重相物質(zhì)迅速沉降到轉(zhuǎn)鼓內(nèi)壁，被螺旋推料器從固相出口排出轉(zhuǎn)鼓體外；同時(shí)比重較小的輕相物質(zhì)則在離心力的作用下形成內(nèi)層料液環(huán)，通過(guò)液相溢流口排出轉(zhuǎn)鼓體外。轉(zhuǎn)鼓與螺旋推料器同時(shí)高速運(yùn)轉(zhuǎn)，由于兩者之間存在一定的轉(zhuǎn)速差，使得沉降在轉(zhuǎn)鼓壁上的固性物不間斷地被螺旋推料器推送至出渣口排出，整個(gè)分離過(guò)程連續(xù)進(jìn)行。 | The purpose of separation is to separate out substances with different mass ratios from mixed fluid. Separation forms include solid-liquid separation,solid-solid separation,liquid-liquid separation and solid-liquid-liquid separation. When mixed fluid enters rotating bowl of centrifuge through feed tube,solids with larger density would rapidly deposit on inner wall of the bowl,forced by centrifugal acceleration.Then spiral pusher pushes deposited solids to taper end of the bowl,ａnd discharges them out of centrifuge from residue outlet. Meanwhile,liquid phase with smaller density forms a liquid ring layer and discharges from bowl through overflow port. The bowl and spiral pusher run at a high speed simultaneously,for there exists speed discrepancy,deposited solids on the wall of bowl could be conveyed to residue outlet by spiral pusher.This separation process carry out continuously. | |
