摘 要

带式输送机经过多年的发展，凭借其结构简单、能耗低、效率高等优点被广泛应用于各个行业，其中在煤炭输送方面应用最多。带式输送机的给料部分是整个输送机物料的源头，对其进行优化设计不仅可以减少物料的散落对周围环境造成的污染还能提升输送机的工作效率和工作性能。因此对带式输送机的给料过程的研究具有非常重要的意义。

本次论文完成了对带式输送机的主要零部件的设计计算并对其进行了三维建模，同时还对输送机的给料过程进行了EDEM仿真。考虑到给料速度、导料侧板与竖直方向的夹角、侧板高度、给料漏斗高度等都对给料过程都有影响，因此对不同影响因素分别进行了仿真分析。

研究结果表明：在一定程度上增高给料漏斗的高度可以增加物料的流动性并且在一定范围内增大侧板与竖直方向上的夹角可以提高输送机的输送效率同时可以增加两侧板上边缘的间距离从而减少物料洒落现象，可以考虑同时匹配增大给料装置的给料量，以达到相互间最优配合，使输送机工作效率更高。

Abstract

After many years of development, ribbon conveyer are widely used in various industries especially in coal delivery because of its simple structure, low energy consumption and high efficiency. Conveyor feed section is the source of the entire conveyor material, optimizing the design of conveyor feed can not only reduce the pollution which caused by material scattered on the surrounding environment but also enhance work efficiency and performance of the conveyor. So it is meaningful to study the process of conveyor feed.

This paper completes the design calculation of the main components of the belt conveyor and its 3D modeling . At the same time the process of conveyor feed is EDEM simulated. The feed rate, feed guide plate and the angle between the vertical direction, side height, the height of the feed hopper and so have an impact on the feeding process, so these different factors are simulated.

The results showed that: increasing the height of the feed hopper to a certain degree can increase the flow of materials . At the same time if you increase the angle with the vertical direction on the side plate to a certain range the transmission efficiency will be increased and the distance between the two material will be reduced .while the spilled phenomenon is reduced also. We can consider to increase feed amount in feed device which will help achieve the best fit between each other . As a result, the conveyor will work more efficiently.

Key words: belt conveyer, 3D modeling , EDEM simulation, material side guide, optimal design

第一章绪论

1.1带式输送机概述

带式输送机指得是以橡胶带、塑料带、钢带、化纤带、钢化纤维带等输送带作为输送物料及牵引工件的连续输送机^[1]。它的特点就是输送带既是输送物料的构件也是牵引构件，这与其他连续输送机械有着显著区别。输送带在托辊上运行，也可以用气垫或者磁垫来代替托辊作为无阻力承载装置支撑输送带的运行。带式输送机凭借其结构简单、输送量大、输送物料范围广等优点成为了连续运输机械中应用最多的一种。在我国带式输送机主要是用于在港口中运送散状物料、在火力发电厂中运送煤料、在矿山中运送金属矿物和煤等^[2]。

1.2带式输送机工作原理

带式输送机的输送带是一个封闭的环形，两端分别有电动滚筒和尾部滚筒，而输送带的中间部分由上下的托辊支撑也可以用气垫或者磁垫代替，托辊安装在机架上，机架的形状随输送路线而变。带式输送机还包括驱动装置、制动装置、拉紧装置、清扫装置等，各自的作用顾名思义。物料通过给料装置落在输送带上并和输送带一起运动。带式输送机主要是上部载货，端部卸货，也可以使用专门的装置进行中间卸载^[3]。
