摘 要
垃圾再生煤是一種新型綠色能源，它具有容易燃燒，火力猛，燃燒完全和排污少的特點(diǎn)。是一種很好的燃料。中國(guó)現(xiàn)在能源利用中，煤占有很大一部分比例。垃圾再生煤可以運(yùn)用到居民日常生活，工業(yè)領(lǐng)域，運(yùn)用前景廣泛。
本文根據(jù)垃圾煤生產(chǎn)線(xiàn)上對(duì)垃圾煤成型擠出機(jī)的工作要求，設(shè)計(jì)出一種可行的擠出機(jī)結(jié)構(gòu)，主要工作包括：
進(jìn)行擠出機(jī)的結(jié)構(gòu)方案論證，設(shè)計(jì)可行擠出結(jié)構(gòu)方案。繪制擠出機(jī)部件的機(jī)構(gòu)裝配圖，主要零件的零件圖。進(jìn)行有關(guān)理論分析和計(jì)算，以滿(mǎn)足強(qiáng)度和使用要求。
分析工作動(dòng)力要求，選擇合適的原動(dòng)機(jī)及減速機(jī)。
編制關(guān)鍵零件的加工工藝卡。對(duì)擠出機(jī)機(jī)中關(guān)鍵部位的零件編制加工工藝卡，可以了解其加工工藝過(guò)程，方便加工制造。用三圍軟件UG完成部件的結(jié)構(gòu)設(shè)計(jì)。
本次擠出機(jī)采用了葉輪擠壓式原理，包含有減速箱的設(shè)計(jì)，擠出機(jī)頭的設(shè)計(jì)，箱體和機(jī)筒的設(shè)計(jì)。擠壓部采用螺旋結(jié)構(gòu)，擠壓部螺旋軸采用懸臂式設(shè)計(jì)結(jié)構(gòu)，機(jī)筒的結(jié)構(gòu)采用組合式結(jié)構(gòu)并內(nèi)裝襯套減少物料對(duì)機(jī)筒摩擦。并在結(jié)構(gòu)設(shè)計(jì)的基礎(chǔ)上進(jìn)行重要零件的校核，確保其的可行性。

ABSTRACT
Regeneration of waste coal is a new type of green energy, it has easy burning, fire, and combustion characteristics of full and less emissions. Is a good fuel. Energy use in China now, coal accounts for a large proportion. Waste recycling coal use to the residents ' daily life, industrial areas, use Outlook extensively.
According to this article on waste coal briquetting waste coal production line extruders working requirements, design a feasible structure of extruder, major work includes:
Structural plan of the extruder, design feasible extrusion structure. Draw out the body assembly drawings of machine parts, parts of the main part. Theoretical analysis and calculation to meet strength and usage requirements.
Analysis of power requirements, select the right prime mover and gearbox.
Processing technology of preparation of key parts of the card. On key parts in extruder machine parts processing technology of preparation of cards, you can understand the process, facilitate the processing and manufacturing. Measurements software UG structure design of the finished part.
Impeller in the extruder adopts the principle of pressure-, containing the gearbox design, design of the extrusion die, tank and barrel design. Extrusion using spiral structure, extrusion screw design of axis-cantilever structure, structure using the modular structure and the contents of the cylinder lining reduces friction material on the barrel. And important parts on the basis of structural design of checking to ensure its feasibility
