【摘要】：印尼滨海砂矿资源丰富,Paragon采矿船为舟山海川船舶机械有限公司为印尼矿业公司设计制造的应用于开采浅海的锡矿的自航绞吸式采矿船,设计要求配备采矿、选矿等一体化配套设备,无需其他设备即可产出矿产。对于滨海矿砂的矿砂类型来说,设计以跳汰机为原型的矿砂选别设备对于提高分选效率具有重大意义。然而该类分选设备中关于跳汰机中床层厚度的检测主要依靠工作人员的经验,由此调节跳汰机的工作参数,不具备更加客观的判断方法。在自动化控制及检测方法不断进步的大背景下,同时为了适应先进生产力的发展要求,有必要设计一套船载智能选矿系统来提升其自动化程度,提高其分选效率。本课题在设计矿砂选别设备之前,介绍了影响其性能的相关参数,根据参数设计要求进行设定。选定床层状态作为控制量,设计与之相关的检测方法以便在分选设备的工作过程中,稳定床层状态,提高分选效率。其次介绍了选矿设备的主要组成设备,简要说明其工作原理及结构组成,围绕粗选设备,完成其三维建模,并对支架进行静力分析从保证其可靠性。针对系统需要实现的功能,对于PLC、变频器及触摸屏进行了选型,设计了选矿系统的硬件及控制电路,编写了PLC程序语言。最后将程序语言导入到MATLAB的simulink模块中进行仿真,仿真结果在一定程度上表明,系统具备维持床层状态的功能,对于提高分选效率具有巨大作用。
[Abstract]:The Paragon mining ship, which is rich in placer resources in Indonesia, is designed and manufactured by Zhoushan Haichuan Shipbuilding Machinery Co., Ltd for Indonesian Mining Company. It is used for mining tin ore in shallow sea. It is designed to be equipped with mining. Mineral processing and other integrated supporting equipment can produce minerals without other equipment. The design of ore sand separation equipment based on jig is of great significance for improving the separation efficiency. However, the detection of bed thickness in jig in this kind of separation equipment mainly depends on the experience of the staff. Thus adjusting the working parameters of the jig does not have a more objective judgment method. Under the background of the continuous progress of automatic control and testing methods, and in order to meet the requirements of the development of advanced productive forces, It is necessary to design a shipborne intelligent mineral processing system to improve its automation and separation efficiency. According to the parameter design requirements, the bed state is selected as the control quantity, and the relevant detection methods are designed to stabilize the bed state during the operation of the sorting equipment. Secondly, the main components of mineral processing equipment are introduced, the working principle and structure of the equipment are briefly explained, and the 3D modeling is completed around the rough separation equipment. According to the functions of the system, the PLC, frequency converter and touch screen are selected, and the hardware and control circuit of the mineral dressing system are designed. Finally, the program language is imported into the simulink module of MATLAB for simulation. The simulation results show to some extent that the system has the function of maintaining the state of the bed and has great effect on improving the sorting efficiency.
