【摘要】 在石油勘探研究中,对矿样中分离出的干酪根进行分析检测是一项重要手段和依据。然而,迄今为止,干酪根的分离提取绝大部分仍依赖于手工操作,存在效率低、耗时长、对环境和操作人员健康威胁大等缺点。因此,干酪根制备的自动化、智能化是未来石油勘探研究亟需解决的重大课题。本文将以此为目标,探讨干酪根制备工艺流程的自动化与智能化设计与实现。论文首先分析了干酪根的传统制备工艺流程,在此基础之上,对干酪根制备系统设计做出需求分析,并提出了适合于自动化实现的、新的制备工艺流程;最后对总体方案进行了规划,对其中的重点与难点进行了详细深入研究。在此之后,根据其实现的不同功能对总体设计方案进行了细分,划分为五部分。主要抓住两个核心:即反应容器设计和平面振动平台设计;以及三个硬件支撑系统:即管路系统、废液处理系统和机柜设计。并有所侧重地分别加以讨论分析。第三章提出了新的反应容器的密封结构设计,并分析了材料对密封结构的影响;第四章提出两种基于偏心曲轴的过约束运动平台结构设计,对它们的运动平稳性作了分析比较;并分析了影响运动平稳性的因素,改进了结构设计;之后详述了运动平台系统的具体结构设计。第五章对管路系统的密封方式做了介绍,并提出一种改进密封结构;之后对废液处理系统的控制方案进行了探讨,讨论了搅拌装置设计的关键技术;最后对系统机柜的设计及器件布局进行了规划。系统硬件构建完成后,结合控制系统对各功能模块和整个系统进行了大量的调试和实验,取得了较满意的结果。本系统设计实现了干酪根制备的自动化和智能化,提高了制备效率,降低了技术人员的劳动强度。其整体规划设计方法可用于同类复杂系统设计。其中,反应容器设计中关于材料和密封结构的讨论,同样适用于其它复杂条件下使用的密封容器;所设计的平面运动平台机构亦可用作其它平面运动机械设计的参考。更多还原

【Abstract】 In the research of oil exploration, the detection and analysis of kerogen separated from Ore samples is an important means. However, till now, the separation of kerogen still depends on manual operation, which is inefficient, time-consuming and a serious threat against the environment and health of operators. Therefore, the intelligentizing and automation of the separation of kerogen, is a significant subject which desiderated to be solved in the research of oil exploration. Aiming at it, the article will discuss the automatic and intelligent design and realization of the technology of the separation of kerogen.Firstly, this article analyses the traditional technology of separation of kerogen. Based on it, a requirements analysis in detail is made on the design of the separation devices of kerogen, and a new method of separation is proposed which suits the automation of it. Finally, a general project is planned, and a deep research is performed on the emphasis and difficulty of the project.According to the different functions, the general project is divided into five parts, including two key points and three hardware support systems. The two key points are the design of reaction vessels and the motion platform, and the three support systems are the pipeline system, the design of cabinet and wastewater treatment system. And all these are discussed on different pivotsIn chapter 3, a new sealing structure design of reaction vessels is proposed, and the influence of materials on sealing structure is discussed. In chapter 4, a comparison of kinetic stability is made between two kinds of over constraint motion platforms with eccentric shafts. The factors impacting the stability of motions are analyzed, and then an optimized design is presented. Following that, a detailed description of the structural design of the platform is presented. In chapter 5, it introduces the sealing forms of pipeline system generally, and puts forward an improved sealing structure. Afterwards, a discussion is carried out on the control project of wastewater treatment, with a focus on the key technology of mixing fittings. At the end of it, it makes a plan on the cabinet design and layout of devices.After the completion of system hardware, a wide and complete debugging combined with the control system is performed on the function modules and the whole system, and it achieves a great success.The design makes the automatic and intelligent control of the separation of kerogen come true, and it also enhances the efficiency and reduces the laboring intensity.The method of planning and design on this system can be used on the similar complex system design, and the conclusion of the discussion on materials and sealing structure, can be used to direct the design of sealing vessels used in complex environments. In the same way, the motion platform designed in this article can be reference to other motion machines.更多还原
