双轴搅拌机-毕业论文.doc

摘 要 双轴搅拌机为螺旋式搅拌机，它的搅拌部件是两根形状对称的同步螺旋转子，两根螺旋轴在旋转时速度同步、方向相反。双轴搅拌机由电机驱动，可用减速机控制转子转动速度，达到最佳的搅拌效果。 双轴搅拌机的主要部件包括，机械外壳、两根螺旋转轴、电机驱动装置、联动装置、配管和盖板等，双轴搅拌机的螺旋轴是最重要的工作部分，两根螺旋轴的旋转方向相反，都具有轴承座、轴承套、轴承盖、叶片和联动装置。包括彼此平行的第一和第二搅拌轴、搅拌叶片和卧式搅拌桶，所述搅拌叶片从第一和第二搅拌轴向四周伸出，并在轴向依次等距排列而在圆周方向依顺时针或逆时针彼此相差一固定角度，使在第一和第二搅拌轴上的搅拌叶片分别形成旋向相反的螺旋状排列；所述第一和第二搅拌轴彼此同步转动并且其叶片交错通过由该第一和第二搅拌轴轴线所确定的平面；在所述搅拌桶一端的顶部设有进料口，而在所述搅拌桶另一端的底部设有出料。采用这种结构，搅拌机的搅拌叶片在搅拌干粉砂浆的同时将干粉砂浆从进料口排向进料口，从而实现生产的连续，有效的提高了生产效率。Abstract Biaxial mixer spiral mixer to its mixing two symmetrical parts are synchronized helical rotor, two screw shaft rotation speed synchronization, in the opposite direction. Biaxial mixer driven by a motor, can control the rotor rotation speed reducer, to achieve the best mixing results. The main components include biaxial mixer, mechanical enclosure, two screw shaft, motor drive, interlocks, piping, and flat tops, dual-axis mixer spiral axis is the most important part, the two helical axis of rotation in the opposite direction , have a bearing, bearing units, bearing caps, leaves and interlocks. Mixing with each other parallel institutions, including the first and second stirring shaft, stirring blades and horizontal mixing barrel, above mixing blade from the first and second axial four weeks out of mixing and axial offset in turn arranged in circle clockwise or counterclockwise direction according to a fixed point of difference with each other, so that in the first and second axis of the mixing blades were stirring the formation of the spiral spin arrangement to the contrary; the first and second mixing shafts rotate simultaneously with each other and their leaves staggered through the mixing of the first and second axes defined plane; in above the top end of the mixing bucket with feed, while the other end of the said mixing drum with the material at the bottom. Using this structure, the mixing blade mixer mixing dry powder in the mortar, while the dry mortar from the inlet to the inlet arrangement in order to achieve c
