【摘要】：带式输送机作为一种重要的散装物料输送设备,生产率高,优势明显,在各个行业都得到了广泛的应用,尤其是通用带式输送机的运用更为常见。但是在实践中,我们发现通用带式输送机存在着零部件数量多、维护维修费用高、起动困难、噪声大、输送带易跑偏且易摩擦起热等问题,严重制约着输送机的发展空间。因此设计出能解决或避免此类问题的新型带式输送机,将会成为输送设备研究的新前沿。本文在研究适应环境的特种带式输送机同时,寻求建立在物理学基础上的运输手段新途径,试图将磁力机械技术引用到带式输送机上,利用磁斥力的特点将胶带与托辊分离,去除托辊,采用非接触式磁悬浮支承,彻底改变传统输送机结构所带来的发展缺陷。为使研究更为方便,对磁垫式带式输送机进行了力学模型的简化,在此基础上,分别研究了磁垫式带式输送机的两种模式,一是利用永磁悬浮支撑模式,二是利用通电线圈电磁悬浮支撑模式。重点研究了永磁支撑模式,分析讨论了永磁体磁悬浮的工作机理,对永磁产生磁力的影响因素如间隙距离、磁体高度、磁性材料等分别进行了有限元仿真分析,绘制了相应的磁场强度图和相关参数影响曲线图,探索了永磁体支撑的优化变量,同时对其平衡稳定性作出了分析。本文还针对磁垫式带式输送机的牵引力计算进行了分析,对其部件机构也进行相关的设计和讨论,尤其是磁性输送带、防磁托辊、防磁滚筒、磁铁质的去除装置等部件给出较为详细的设计及设计思路。最后举例说明磁垫式带式输送机的经济性。另外,笔者在文中对其他磁垫式构想设计和思路也进行了简单说明。
[Abstract]:As an important equipment for conveying bulk materials, belt conveyor has high productivity and obvious advantages. It has been widely used in various industries, especially in the use of universal belt conveyor. However, in practice, we find that the general belt conveyor has many problems, such as large number of parts and components, high maintenance cost, difficult starting, high noise, easy deviation of conveyor belt and friction and heat, etc., which seriously restricts the development space of conveyor. Therefore, the design of a new belt conveyor which can solve or avoid such problems will become a new frontier in the research of transportation equipment. In this paper, at the same time of studying the special belt conveyor which adapts to the environment, we seek a new way of transportation based on physics. We try to apply the magnetic mechanical technology to the belt conveyor and separate the belt from the roller by using the characteristic of magnetic repulsion force. Remove roller, adopt non-contact magnetic suspension support, completely change the traditional conveyor structure caused by the development defects. In order to make the research more convenient, the mechanical model of magnetic cushion belt conveyor is simplified. On this basis, two modes of magnetic cushion belt conveyor are studied, one is to use permanent magnetic suspension support mode. The second is the use of electrified coil electromaglev support mode. The working mechanism of permanent magnet magnetic levitation is analyzed and discussed. The influence factors such as gap distance, magnet height and magnetic material are simulated by finite element method. The corresponding magnetic field intensity diagram and the influence curve of relative parameters are plotted, and the optimization variables of permanent magnet bracing are explored, and the equilibrium stability of the permanent magnet is analyzed. In this paper, the traction calculation of magnetic cushion belt conveyor is analyzed, and the relevant design and discussion of its component mechanism are also carried out, especially the magnetic conveyor belt, anti-magnetic roller, etc. The design and design idea of magnet removal device and other parts are given in detail. Finally, an example is given to illustrate the economy of magnetic cushion belt conveyor. In addition, the author also gives a brief explanation of other magnetic cushion design and ideas in this paper.
