摘   要

      工業(yè)型煤是一種清潔、高效的新型燃料,廣泛應(yīng)用于電力、冶金、鑄造、化肥等工業(yè)領(lǐng)域。目前我國(guó)工業(yè)型煤的生產(chǎn)工藝主要采用粉煤添加粘結(jié)劑和一些輔料低壓成型,以往的研究主要集中在成型工藝和粘結(jié)劑方面,對(duì)成型機(jī)械的研究開發(fā)甚少。事實(shí)上,成型機(jī)械是型煤生產(chǎn)的關(guān)鍵設(shè)備,
本文描述的是一種中高壓對(duì)輥成型設(shè)備的設(shè)計(jì)與實(shí)現(xiàn)。
成型力是由液壓系統(tǒng)提供，可以產(chǎn)生很高的成型壓力。而且有液壓的防止過載功能。提高了型煤的質(zhì)量還能有效保護(hù)機(jī)器，不受意外傷害。
煤要成型就要有準(zhǔn)確的對(duì)中性，該傳動(dòng)系統(tǒng)采用同步齒輪箱，而且采用帳套連接技術(shù)可以進(jìn)行少量的無級(jí)調(diào)節(jié)，保證有良好的同步對(duì)中性，提高了機(jī)器的運(yùn)轉(zhuǎn)精度和型煤率。
采用變頻調(diào)速螺旋加料裝置。使送料連續(xù)，還有一定的預(yù)壓力。變頻調(diào)速可以根據(jù)產(chǎn)量,可以靈活地調(diào)整加料螺旋的旋轉(zhuǎn)速度,以滿足對(duì)輥成型機(jī)對(duì)加料速度、加料壓力及物料密度的匹配要求,提高了工業(yè)型煤的成球強(qiáng)度
機(jī)架采用螺栓拉緊，不但使得制作簡(jiǎn)便、拆裝方便,而且機(jī)架的承載能力也強(qiáng),滿足對(duì)輥成型機(jī)的工作要求。

 關(guān)鍵詞:成型機(jī)； 對(duì)輥； 同步減速機(jī)；

ABSTRACT

 Industrial briquette is a clean, efficient new fuel, widely used in the electricity, metallurgy, casting, chemical fertilizers and other industrial fields. At present, China's industrial briquette production techniques used mainly coal binder and add some excipients low pressure molding, Previous studies focused mainly on forming processes and binder, the right molding machinery little research and development. In fact, molding machinery is briquette production of key equipment.
 This paper describes a high-pressure China to roll molding equipment design and implementation
 Forming power of hydraulic systems can produce high pressure molding. But also to prevent the hydraulic overload functions. Improve the quality of coal can effectively protect machines from accidents.
 Coal will be forming an accurate pair of neutral, the use of synchronous transmission gearbox, Zhang Tao and using technology for linking a small number of no-regulation, to ensure a good synchronization of the neutral, improve the functioning of the machine precision and briquette rate.
 Using variable frequency spiral feeder. Feeding enable continuous, there will be some pressure on the advance. VVVF can output and the flexibility to adjust the feed screw rotation speed, to meet the roll forming machine for the feeding rate, feed pressure and density of materials matching requirements, enhance industrial briquette ball into strength
 Rack with bolt taut, not only makes the production of simple and easily reassembled, and the rack-bearing capacity, meet the roll forming machine and job requirements.
