| 针对传统的刮刀卸料离心机使用过程中，产品的晶粒形状易受到破坏、转鼓内易形成残余滤渣层而严重影响后续过滤并造成较大的物料损失的问题，笔者提出了一种液压驱动式双轴转鼓结构。使用液压系统驱动内轴，使之可以在外轴内部移动实现翻袋自动出料。外轴两端用轴承支撑，固定在机架上，由电机和同步带轮带动作旋转运动；外轴和内轴之间镶有滑块，保证外轴和内轴同步转动；设置精准称量装置和进行工艺优化控制，使装备结构紧凑，可实现离心机转鼓内物料质量的精确测定和过滤、洗涤及卸料等操作的智能化运行。试验结果表明：该设计实现了全自动洁净过滤，生产过程中不留残余滤饼、不损坏晶体颗粒，对物料适应性强，产品的纯度和收率都得到了提高。该设计降低了生产成本，提高了生产效率。 |

| Aiming at the problems of the grain shape vulnerable to be damaged of the material and the formation of residual slag layer in the drum which affected the subsequent filtration resulting in great material loss in the use of traditional filter centrifuges, a hydraulic driven double shaft drum structure was proposed. The inner shaft was driven by hydraulic system to move inside the outer shaft to realize the automatic discharge of the bag turning. Both ends of the outer shaft were supported by bearings, fixed on the frame, and rotated by motor and synchronous belt wheel. The outer shaft and the inner shaft were set with a sliding block to ensure the synchronous rotation of the outer shaft and the inner shaft. The precise weighing device and process optimization control were set up to make the equipment compact, which can realize the accurate measurement of the material quality in the centrifuge drum and the intelligent operation of filtration, washing and unloading. The test results show that the designed equipment realizes fully automatic clean filtration, leaving no residual filter cake and no damage to crystal particles in the production process, and has strong adaptability to materials. The purity and yield of the product have been improved. The design reduces the production cost and improves the production efficiency. |
