EX1000高效二次風(fēng)選粉機（傳動及殼體部件）設(shè)計
摘要：為了提高水泥粉磨系統(tǒng)中選粉系統(tǒng)的選粉效率，降低循環(huán)負(fù)荷，本課題設(shè)計了水泥圈流系統(tǒng)中采用的二次風(fēng)選粉機。二次風(fēng)選粉機是在高細(xì)轉(zhuǎn)子選粉機的基礎(chǔ)上，集懸浮分散、預(yù)分級和平面渦流分級技術(shù)于一體，專為水泥磨系統(tǒng)適應(yīng)新標(biāo)準(zhǔn)而設(shè)計的專利產(chǎn)品。運用類比法，結(jié)合其他選粉機的優(yōu)點，確定殼體的整體布局方案。在適當(dāng)位置布置約束內(nèi)錐，以穩(wěn)定選粉室內(nèi)的氣體流場及增強二次選粉的效果；細(xì)粉分離與收集裝置采用高效低阻旋風(fēng)筒,提高各級細(xì)粉和超細(xì)粉的收集量。殼體的改進(jìn)有利于降低系統(tǒng)風(fēng)的阻力，提高選粉效率。選粉機采用整體緊湊設(shè)計，大大降低了占據(jù)空間，且大大提高了選粉效率。機體工作運行平穩(wěn)，安裝維修方便。選粉機設(shè)計的主要特點是采用二次風(fēng)結(jié)構(gòu)，即在選粉機進(jìn)風(fēng)管道上增設(shè)一個旁路支風(fēng)管，作為二次風(fēng)管，并設(shè)置一個機外調(diào)節(jié)的風(fēng)閥，二次風(fēng)氣流切向進(jìn)入選粉室內(nèi)。這樣可以有效地控制上升風(fēng)速，改變和控制細(xì)度。二次風(fēng)的導(dǎo)入，對粗顆粒能進(jìn)行二次切割，改善成品的顆粒級配。

Design of EX1000 high efficiency powder-selecting machine with secondary air (transmission and shell parts)
Abstract：In order to improve the powder-selecting efficiency of the powder-selecting system in cement grinding system, reduce circulation load, the powder-selecting machine with secondary air used in the cement loop system is designed. The powder-selecting machine with secondary air, which is combined the aerosol disperse, the pre-gradation with the plane vortex classified technology in a body, is specially designed to adapt to the new standard for cement grinding system in the foundation of the high thin rotor powder selecting machine. Adopting analogy method and combining the advantage of others，the overall arrangement scheme of the shell is determined. In order to stable the flow field in powder-selecting room and strengthen the effect of secondary powder-selecting, constrained inner cone is arranged in the appropriate position. The thin powder separation and the collecting device use the high efficiency coclone with low resistivity, thus the collection property of the fine dust and the ultra fine dust is enhanced. The improvement of the shell is of benefit to reduce the resistance of the system wind and improve the powder–selecting efficiency. The powder-selecting machine is arranged rationally and compactly, occupying little space and improving powder-selecting efficiency greatly. It is the main characteristic that the structure with secondary air is adopted in the powder-selecting machine. By way of secondary air duct, an additional bypass tuyere is set on air-supply line of the powder-selecting machine. In addition, the wind valve for adjustment is established outside the machine, so that secondary air currents flow into power selecting room in circumferential direction. This may be able effectively to control the rising wind speed, change and control fineness. Because of inducting secondary air, the coarse particles can be selected secondly, and grain grading of the finished product is improved.
