摘要
沥青混凝土搅拌设备是生产沥青混合料的主要设备，在路面施工中占有重要的地位，所生产的沥青混合料的质量好坏，直接影响着沥青路面的质量。对沥青混凝土搅拌设备生产过程实现监控与动态管理是非常必要的。因此，研究设计基于GPRS网络的沥青混凝土搅拌设备的监控系统具有广泛的工程实用价值。其中固一液两相搅拌操作是最常见的操作，对固一液悬浮浆液池中的固液两相流场进行研究，进而讨论固体浓度对浆液池内液相流场的影响规律，是固一液搅拌研究工作的重要组成部分。本文首先从混凝土生产特别是碾压混凝土生产的特点和影响混凝土生产质量的因素入手，设计出一种连续式搅拌设备的总体研制方案，然后通过深入分析连续式碾压混凝土搅拌机理和连续配料方案，提出了采用皮带重量连续配料方案和双卧轴连续搅拌机设计方案。最后，通过试验验证，说明连续式碾压混凝土搅拌设备的生产的混凝土完全能满足水工混凝土规范的要求，连续式碾压混凝土搅拌设备的设计正确，方案可行，同时由于其具有的明显优势，可以大量推广。关键词：沥青混凝土搅拌设备 结构设计 人机界面等
Abstract
Asphalt mixing plant is a main equipment of the production of the asphalt—concrete，and plays an important role in the construction of road．The quality of the asphalt—concrete made from it has a direct impact on the quality of asphalt pavement．The monitoring and dynamic management of the asphalt mixing plant is very essential．Therefore，the research and design of the monitoring system for the asphalt mixing plant based on GPRS works with a vide range ofpractical value．The operation of blender relates to fluid flow，heat transfer and mass transfer, and other physical and chemical processes．Among them，solid-liquid two—phase mixing operation is the most common operation techniques．Study on solid—liquid two-phase field in solid-liquid suspension agitator Tank and discuss the influence law of solids concentration on the liquid flow field are important components in the solid-liquid mixing research．This thesis based on the concrete production,especially the feature of RCC production and the factors affecting concrete production quality,designed a overall development plan of continuous mixing plant，and then through in-depth analysis of continuous RCC mixing mechanism and way of continuous ingredients，proposed a scheme that using belt continuous weight measuring method and double axle continuous mixer．At last，through the test verification,illustrated the concrete produced by continuous concrete mixing plant which is designed and researched，Can completely meet the requirement of hydraulic concrete，simultaneously,because of its advantages，it Can promote widely．Key words：the asphalt mixing plant，structural design，；human—machine interface
