工業(yè)型煤成型機(jī)的設(shè)計(jì)
摘要
本論文描述了GDC955/45對輥成型機(jī)的設(shè)計(jì)和計(jì)算過程,并對關(guān)鍵部位進(jìn)行了分析和研究。
工業(yè)對輥成型機(jī)是一種應(yīng)用到型煤生產(chǎn)中的關(guān)鍵設(shè)備,屬于工程機(jī)械。對輥成型機(jī)是由壓輥、軸承、給料系統(tǒng)、承壓支架、減速器(傳動裝置)、潤滑系統(tǒng)、等機(jī)構(gòu)組成。與傳統(tǒng)低速重載、剛性不足的老式減速器相比,它具有體積小、重量輕、成本低廉等優(yōu)點(diǎn)。
對輥組件直接關(guān)系到型煤煤球的成球質(zhì)量,工業(yè)型煤是一種廣泛應(yīng)用到冶金、制造化肥、電廠等工業(yè)領(lǐng)域、對節(jié)能、環(huán)保都具有重要意義的清潔、高效的新型燃料。本設(shè)計(jì)在對輥輥輪與對輥軸之間采用脹套無鍵連接技術(shù),兩對對輥輥輪之間必須具有良好的對中性,否則會影響成型質(zhì)量。采用脹套無鍵連接的優(yōu)點(diǎn)是可以方便的松開脹套對輥輪進(jìn)行調(diào)整,保證型煤的成球率。
在給料系統(tǒng)中,本裝置采用了螺旋強(qiáng)迫加料裝置,采用此裝置可滿足對輥成型機(jī)對加料速度,加料壓力及物料密度的匹配要求大大提高了型煤的成球強(qiáng)度。
本設(shè)計(jì)機(jī)架采用螺桿連接結(jié)構(gòu),此種機(jī)架制作簡便,而且承載能力強(qiáng),拆裝方便,基本滿足大型對輥成型機(jī)的工作要求。

ABSTRACT
The process of the design and calculations GDC955/45 roll-type forming machine is described, and the crucial units are analyzed and investigated.
Industry roll-type forming machine is a crucial device applied to the manufacturing of shape-coal. It’s a kind of engineering machine. Roll-type machine consists of units such as pressing rolls, bearing, feeding system, bearing beam ,three-staged velocity-reduction gearbox (transmission system), lubricating system, and hydraulic pressing system, etc .compared conventional forming machine ,with heavy-burden and inadequate rigidity, it is of small-volume,;low-weight and low-cost.
Double rolls have a direct relation to the forming-quality of shape-coal. Industry shape-coal is a new-type of clean ,effective fuel which is widely applied to various industry field such as metallurgical industry ,manufacturing industry chemical fertilizer, calcium carbide and has a vital significance to energys-aving and environment-protection business.
Design in the paper uses expanded–casing and no-key connecting technology and it must be guaranteed that it must be of good centering character-
istic betwween ball groves of the two rolls. Otherwise the forming quality will be
seriously affected. Use expanded-casing and no-key connecting technology, rolls can can be conveniently adjusted by loosning expanded-casing to ensure the forming rate of shape coal.
In the feeding system, the frequency conversion-timinghelix feeding equipment is adopted in the system which can satisfy the requriements of speed of filing the press of the feeding and the match of the material. So ,it can also improve the intensity of the figuration of the briquette.
Design of structure uses construction of pressing rolls which can be easily removed or easily altered. This kind of structure is of simple-make and bear heavy loads. Hence,the working requirements os large scale roll-type forming maching are satisfied.
Keywords: roll-rype forming machine; industry shape-coal; thefrequency conversion-timing helix feeding system; hydraulic loading .
