摘　　要：针对现有充填料浆搅拌设备制浆不均匀、拆装检修耗时长、磨损快、使用寿命短等问题,开发研制出GSJ-100型尾砂充填料高速搅拌机。搅拌机内腔布置双层8根搅拌杆,对充填料浆进行充分剪切与碰撞,制得的充填料浆浓度高、均匀性好;圆筒形机壳采用两侧端盖密封,实现了不拆机生产线上进行维护和检修,提高了生产效率;针对搅拌杆、转子部件等易磨损件进行耐磨设计,大幅提高了设备的使用寿命;各零部件接触部位采用密封设计,保证了设备工作过程中不漏浆,密封效果好。工业试验结果表明,采用该搅拌设备制得的充填料浆或试块的强度、流动性和均匀性均能较好地满足充填设计指标,具有较广泛的应用前景。Aiming at the problems of uneven slurry preparation,long time of disassembly and mainte⁃nance,GSJ-100 high-speed mixer,with fast wear and short service life of the existing filling slurry mixing equipment,for tailings filling material was developed.The double-layer 8 stirring rods were arranged in the inner cavity of the mixing equipment to fully shear and collide the filling slurry,and the obtained filling slur⁃ry had high concentration and good uniformity.The cylindrical casing is sealed on both sides of the end cov⁃er,which realizes the maintenance and overhaul on the production line without dismantling the machine,and improves the production efficiency.The wear-resistant design of the easy-to-wear parts such as mixing rods and rotor parts has greatly improved the service life of the equipment;the contact parts of each compo⁃nent are sealed to ensure that the equipment does not leak slurry during operation and the sealing effect is good.The industrial test results show that the strength,fluidity and uniformity of the filling slurry or test block prepared by the mixing equipment can meet the filling design index well,and have a wide application prospect.
