双轴桨叶式混合机设计
摘要
随着现代化饲料工业的发展，饲料厂规模的不断扩大，对混合机的均匀度的要求不断提高。随着液体添加量增加，传统的卧式双螺带混合机已不能满足上述要求，于是新一代高性能双轴桨叶式混合机便应运而生。该混合机适应粉状、颗粒状，片状及粘稠状物料的混合；其混合周期短，混合均匀度高，提高了饲料厂生产效率。
本文设计了可满足饲料生产需要的双轴桨叶式混合机，该机主要由两根相反旋转的转子组成，转子上焊有多个特殊角度的桨叶，该机在电机的驱动下,桨叶带动物料一方面沿着机槽内壁作逆时针旋转；一方面带动物料左右翻动。在两转子的交叉重叠处形成一个失重区，在此区域内，不论物料的形状、大小和密度如何，都能使物料上浮，处于瞬间失重状态，以此使物料在机槽内形成全方位连续循环翻动，相互交错剪切，从而达到快速柔和和混合均匀的效果。这样，两侧的物料便相互落人两轴间的腔内。本文详细的介绍了主要部件的设计和计算过程，本文设计的双轴桨叶式混合机可促进饲料业的发展，提高饲料的利用率，降低生产成本，可以为饲料的混合提供参考。

Along with the de ve lopme nt of modern in dustr y, animal feed f actor y continue s to ex pand th e scale o f mixe r, mixin g with requ ire ment o f impro ving forage additive quan tity of liquid, trad itio n al hor izon tal double s crew with mixer a lread y canno t satisf y the require ment of new gener atio n of high perfor mance. Then biaxial blade s mixe r pr oduce and b iaxia l b la des mixer aris es at the histo ric mo ment. This machin e is wide ly u sed in the food, feed, che mica l,phar maceutical, pes ticide, and o ther indu strie s powd e r, g ranu le, flake, mis cellaneous a nd mixed s tick y mate r ials, Mixed c yc le is sh ort, mixed unifor mity:Des igned to mee t the needs o f fe ed production twin-sh aft padd le mixe r, whic h ma inly consists o f two con tra r y ro tation ax is to be phase aligned and mounted on a shaft abo ve the blade co mponen ts.Weld has mu ltip le special angle of the b lades on the ro to r, this machine is d riven b y the mo tor and blade s c arr y mater ial alo ng the inne r wa ll of the tank counterc lock wis e on the one hand；abou t o ne hand carr y mater ial turned o ve r.
