摘     要

磁傳動(dòng)是一種將動(dòng)密封轉(zhuǎn)化為靜密封的方法，對(duì)于高壓釜和反應(yīng)介質(zhì)是易燃、易爆、劇毒的反應(yīng)釜，磁傳動(dòng)是唯一的選擇。本文根據(jù)底入式磁傳動(dòng)攪拌器設(shè)計(jì)要求與基本參數(shù)，進(jìn)行零部件具體設(shè)計(jì)、計(jì)算及校核、總體設(shè)計(jì)及基于Pro-E的三維造型及動(dòng)態(tài)仿真。底入式與傳統(tǒng)頂入式磁傳動(dòng)攪拌器相比在高轉(zhuǎn)速的情況下具有明顯的優(yōu)勢(shì)，但設(shè)計(jì)上有其難點(diǎn)。新開發(fā)的底入式磁傳動(dòng)攪拌器采用帶有彈性隔離膜的新結(jié)構(gòu)壓力自平衡裝置,其保證了磁傳動(dòng)腔體內(nèi)的油壓始終高于釜內(nèi)物料壓力，防止釜內(nèi)腐蝕氣體及固體顆粒泄漏到磁傳動(dòng)腔體，避免了軸承和磁組件受損。該設(shè)計(jì)解決了目前國(guó)內(nèi)外底入式磁傳動(dòng)攪拌器存在的問題，確保了磁傳動(dòng)攪拌器長(zhǎng)期正常工作，這種磁傳動(dòng)攪拌器將被廣泛的應(yīng)用于化工等行業(yè)。

ABSTRACT

Magnetic transmission is a measure which can be changed dynamic seal into static seal. For autoclave with high pressure and chemical reactor in which the reacting media is inflammable, or explosive, or highly toxic, or evaporable, the magnetic transmission should be an only choice. In this paper, according to the type of magnetic transmission blender design requirements and basic parameters, specific design, calculation and parts check, overall design and based on the Pro-E 3D modeling and dynamic simulation. Magnetic transmission blender installed from bottom compared with form top has obvious advantages at a high speed, but the design was with some difficulties. The new pressure auto-balancing device with a elastic separation film were used in newly developed magnetic transmission blender installed from bottom. It assured that the oil pressure of the body cavity of magnetic transmission is always higher than the material pressure of the autoclave, preventing the corrosion gas and the solid particle in the autoclave to leak out of the cavity of the magnetic transmission. The design solves the home and abroad magnetic transmission blender existing problems and ensures the magnetic transmission blender long-term work normally. This kind of magnetic transmission blender will be widely used in chemical industry.
