摘   要

     工業型煤是一種清潔、高效的新型燃料,廣泛應用于電力、冶金、鑄造、化肥等工業領域。目前我國工業型煤的生產工藝主要采用粉煤添加粘結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劑方面,對成型機械的研究開發甚少。事實上,成型機械是型煤生產的關鍵設備,
本文描述的是一種中高壓對輥成型設備的設計與實現。
成型力是由液壓系統提供，可以產生很高的成型壓力。而且有液壓的防止過載功能。提高了型煤的質量還能有效保護機器，不受意外傷害。
煤要成型就要有準確的對中性，該傳動系統采用同步齒輪箱，而且采用帳套連接技術可以進行少量的無級調節，保證有良好的同步對中性，提高了機器的運轉精度和型煤率。
采用變頻調速螺旋加料裝置。使送料連續，還有一定的預壓力。變頻調速可以根據產量,可以靈活地調整加料螺旋的旋轉速度,以滿足對輥成型機對加料速度、加料壓力及物料密度的匹配要求,提高了工業型煤的成球強度
機架采用螺栓拉緊，不但使得制作簡便、拆裝方便,而且機架的承載能力也強,滿足對輥成型機的工作要求。

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.
