螺旋输送机总体设计

摘要

随着社会机械行业的发展，我国螺旋输送机逐渐向机构简单，操作方便方向发展，机体密封结构能有效地防止粉尘污环境。主要用于火力发电厂的煤粉系统，对冶金、化工、建材、轻工等系统也广为利用，工程实际中较常用的为固定式、水平慢速螺旋输送机。主要特点是：结构简单、外形尺寸小、造价低、密封性好、可实现多点进卸料、对物料有搅拌混合作用，操作安全、方便，制造成本低。但其输送距离小，叶片和机壳易磨损，能耗较高，对物料破碎作用较强。GX型螺旋输送机是我国最早定型生产的通用性生产设备。

本文论述了螺旋输送机的现状和发展及其设计理论和方法。在过去的20年里，我国机械运输部门完成了一些标志性的研究与开发工作，应用这些成果所制造的装备基本满足了工业的需求，其中应用计算机能使模型、测量和理论相互检验。本设计为未来输送机的将向着大型化发展、扩大使用范围、物料自动分拣、降低能量消耗、减少污染等方面发展提供理论依据。大型化包括大输送能力、大单机长度和大输送倾角等几个方面。长距离、大运量连续输送物料的更完善的输送机结构。若用于生产将扩大输送机的使用范围，发展到能在高温、低温条件下有腐蚀性、放射性、易燃性物质的环境中工作，以及能输送炽热、易爆、易结团、粘性物料的输送机。也为生产提供一定的参考。

Abstract

With the development of social machinery industry，Gradually to the institutions of our screw conveyor is simple, user-friendly direction，The structure of the body can effectively sealed to prevent dust pollution environment。Mainly used in coal-fired power plants of the pulverized coal system，Metallurgical, chemical, building materials, light industry and other systems are also widely use，More commonly used in engineering practice for the fixed, horizontal screw conveyor slow。The main characteristics：Simple structure, small size, low cost and good sealing performance, enabling multi-point discharge into the mixing mixing materials，Operational safety, convenience, low cost manufacturing。However, its transmission from the small, easy to wear and tear leaves and chassis, high power consumption, the role of a strong material broken。GX-type screw conveyor stereotypes of China's first general-purpose production of production equipment.

This article discusses the current status and development of screw conveyor and its design theory and methods. In the past 20 years, China's machinery to complete the transport sector a number of landmark research and development work, the application of these results by equipment manufacturers to meet the basic needs of the industry, which enables the application of computer models, measurement and theory of mutual inspection. The conveyor design for the future will be toward the development of large-scale, expanding the use of the scope of automatic sorting of materials to reduce energy consumption, reduce pollution and provide a theoretical basis to develop. Including large-scale transmission capacity, large single-length and inclination of several aspects of transportation.

Long-distance, large capacity for delivery of materials to improve the conveyor structure. If used in the production will expand the use of conveyor to develop in the high-temperature, low temperature conditions, corrosive, radioactive, flammable substances in the environment, as well as to transport hot and explosive, easy to knot groups, viscous material the conveyor. As well as to provide a reference for production.
