【摘要】：带式输送机是大宗散装物料运输的主要设备,广泛应用于矿山、电力、港口、焦化等工矿企业中的产品和原料的运输环节中。目前应用的带式输送机不能根据其上载荷大小而调整带速,只能恒速运行,带来能源的巨大浪费和设备的加速损耗。针对上述问题,本文提出了多级长距离带式输送机联合调速节能设计方案,可用于由多级(2级及2级以上)带式输送机组成的运输系统中,实现运输系统根据载荷即时调速的节能运行。本文中介绍了当前国内外带式输送机节能技术状况,分析了本课题的必要性及项目实施基础,提出了系统的设计思路：对由n台带式输送机串级组成的运输系统,节能系统监测其中第一台带式输送机的载重量与带速的情况,再依此情况调整后续的n-1台带式输送机的带速。在软件中使用了二维模糊控制算法,比较带式输送机带速与运量匹配情况是否最优。若不是最优,则根据各级带式输送机的长度和运行状况延时调整变频器的输出频率和电压,实现对电动机转速的控制,最终改变带式输送机带速,避免编号为2到n的n-1台带式输送机空载高速、轻载恒速运行而造成的电能浪费,实现了运输系统节能的目标。本文根据带式输送机实际状况,以煤矿企业带式输送机的设计与选型为例,对电动机运行能耗进行了分析。详细介绍了节能系统中硬件的设计和采用的二维模糊控制算法,对节能效果进行了理论分析和MATLAB仿真,得出了使用该节能系统后,运输系统平均节能率为10%的设计结果。多级长距离带式输送机联合调速节能系统课应用于煤矿、冶金、焦化、电力及港口等行业,具有很好的节能降耗效果。最后,本文对节能系统设计进行总结,做了工业化推广应用展望分析；并对本系统设计中未能解决的问题予以陈述,为今后的进一步完善提供一定的参考。
[Abstract]:Belt conveyor is the main equipment for bulk material transportation, which is widely used in the transportation of products and raw materials in mines, electric power, ports, coking and other industrial and mining enterprises. The belt conveyor used at present can not adjust the belt speed according to its load size, but can only run at constant speed, which brings huge waste of energy and acceleration loss of equipment. In view of the above problems, this paper puts forward a design scheme of combined speed regulation and energy saving for multistage long distance belt conveyors, which can be used in the transportation system composed of multistage belt conveyors of grade 2 and above. The energy-saving operation of the transportation system is realized according to the load real-time speed regulation. This paper introduces the current energy saving technology of belt conveyor at home and abroad, analyzes the necessity of this subject and the implementation basis of the project, and puts forward the design idea of the system: for the transportation system composed of n belt conveyors, The energy saving system monitors the load and belt speed of the first belt conveyor and adjusts the belt speed of the subsequent n-1 belt conveyor according to this situation. A two dimensional fuzzy control algorithm is used in the software to compare the optimal matching of belt speed and transportation capacity of belt conveyor. If it is not optimal, the output frequency and voltage of the converter are adjusted according to the length and running condition of the belt conveyor at all levels, and the speed of the motor is controlled, and the belt speed of the belt conveyor is finally changed. The energy waste caused by no-load high speed and light load constant speed running of n-1 belt conveyor numbered from 2 to n is avoided and the goal of energy saving of transportation system is realized. According to the actual condition of belt conveyor, this paper analyzes the energy consumption of motor operation by taking the design and selection of belt conveyor in coal mine enterprise as an example. This paper introduces the design of the hardware and the 2-D fuzzy control algorithm in the energy-saving system in detail. The energy-saving effect is analyzed theoretically and simulated by MATLAB. The design result of the average energy saving rate of the transportation system is 10% after the use of the energy-saving system. Multi-stage long distance belt conveyor combined speed regulating and energy saving system course is applied in coal mine, metallurgy, coking, electric power and port, etc. It has a good effect of saving energy and reducing consumption. Finally, this paper summarizes the design of energy saving system, makes the prospect of industrialization promotion and application, and describes the problems that have not been solved in the design of the system, which provides a certain reference for further improvement in the future.
