關(guān)鍵詞:臥式螺旋卸料沉降離心機(jī) 磁性材料 濕法生產(chǎn)
摘要
離心機(jī)是利用離心力,分離液體與固體顆?;蛞后w與液體的混合物中各組分的機(jī)械。 離心機(jī)主要用于將懸浮液中的固體顆粒與液體分開(kāi);或?qū)⑷闈嵋褐袃煞N密度不同,又互不相溶的液體分開(kāi)(例如從牛奶中分離出奶油);它也可用于排除濕固體中的液體,例如用洗衣機(jī)甩干濕衣服;特殊的超速管式分離機(jī)還可分離不同密度的氣體混合物;利用不同密度或粒度的固體顆粒在液體中沉降速度不同的特點(diǎn),有的沉降離心機(jī)還可對(duì)固體顆粒按密度或粒度進(jìn)行分級(jí)。本設(shè)計(jì)通過(guò)計(jì)算和校核,設(shè)計(jì)一個(gè)臥式螺旋卸料沉降離心機(jī),用以對(duì)磁性材料的濕法加工進(jìn)行物料篩選分離,滿足該工藝流程中的要求。

Abstract
Centrifuge is the use of centrifugal force to separate liquid and solid particles or liquid mixtures and liquid components of the machinery. Centrifuges will be mainly used for suspension of solid particles and liquid separately; or emulsion density of two different and separate from each other dissolving liquids (for example, isolated from butter milk); it can also be used to excluded from the wet solid in the liquid, such as washing clothes and dry off; special separator tube speed can also be separated from gas mixtures of different densities; the use of different density or particle size of solid particles in the liquid velocity different characteristics, there are centrifuges can also be the settlement of solid particles by density or particle size classification. By calculating the design and verification, the design of a horizontal spiral centrifuge discharge settlement to the wet processing of magnetic screening material separation, to meet the requirements of the process.
