Consequently the proportion of diameters, the high strength, the high holes rate and the high output of raw meal pellets could be assured of. According to the new requirements, the structure, the transmission system and the drawknife system of YQP36 Disc Prewatering Pelletizer are improved and designed. This design has been completed by the method which combines theories design with experience design. The transmission system and drawknife system are optimized basing on that the strengths of chassis and support are assured with analogy design. Firstly, the projects of designation and improvement of prewatering pelletizer are demonstrated, including the structure, the ways of delivering the motivation and drawknife system by referring some improvement experience from production practice; Secondly, based on the analytical results, axial force, the torque and power are computed so that the electromotor, decelerator and other corresponding components could be determined; Thirdly, according to the parameters of the parts which has already been assured, the simple exercise diagram of the transmission device is analyzed and drawn up and the ratios of all levels are assigned. Then the structure design is carried on and the strength of part is followed to be checked. The ways of lubricant and seal of the equipment are determined in succession. Finally, the whole overall arrangement scheme of YQP36 prewatering pelletizing equipment is designed. This design is in the light of the principle of the high yield, high quantity of pelletizing and stable operation. In addition, the requirements of YQP36 will be satisfied, including economy of energy, economy, environmental protection and enlargement.Key words: pelletizing; prewatering; drawknife; raw meal pellet目　录1 前 言………………………………………………………………………………………12 总体方案论证……………………………………………………………………………22.1 料球的技术要求及对成球盘的技术调整分析………………………………………………22.2 盘体的技术分析论证……………………………………………………………………22.3传动机构的技术分析论证…………………………………………………………………22.4刮刀系统的分析论证………………………………………………………………………22.5 刮刀盘、刮刀杆和刀头分析论……………………………………………………………33 盘式预加水成球机综合参数计算………………………………………………………43.1生产能力计算……………………………………………………………………………43.2功率计算…………………………………………………………………………………43.3 成球机盘高计算…………………………………………………………………………43.4 成球机转速计算…………………………………………………………………………53.5圆盘倾角计算……………………………………………………………………………53.6料球运动基本方程………………………………………………………………………54机械传动装置的总体设计………………………………………………………………84.1 选择电机………………………………………………………………………………84.2 选择减速机 ………………………………………………………………………………84.3计算传动装置的各参数…………………………………………………………………95机械传动件设计…………………………………………………………………………115.1皮带传动设计……………………………………………………………………………115.2齿轮传动设计……………………………………………………………………………135.3 Ⅲ轴设计及校核…………………………………………………………………………165.4 轴承校核………………………………………………………………………………205.5 双键（Ⅲ轴）设计校核（普通平键）…………………………………………………………215.6盘体固定螺栓校核………………………………………………………………………216传动机构的密封润滑……………………………………………………………………236.1密封……………………………………………………………………………………236.2润滑……………………………………………………………………………………237预加水盘式成球机的总体设计…………………………………………………………248预加水盘式成球机使用维护和修理……………………………………………………258.1预加水盘式成球机的使用维护……………………………………………………………258.2预加水盘式成球机的修理与修理周期……………………………………………………259 结 论……………………………………………………………………………………27参考文献……………………………………………………………………………………28致 谢………………………………………………………………………………………291 前言预加水小料球快速煅烧技术，小料球快速烧成技术是立窑煅烧的一项重要技术进步，目前应用十分成功的企业并不多，主要原因是前几年预加水成球系统的控制技术和设备还不太过关，小料球的操作控制要点还没完全掌握，目前预加水成球技术已经发展到第六代产品，设备及控制系统基本过关。

这些都是能否取得高产量、高质量料球的保证，从而提高水泥的煅烧质量和产量 本课题来源于江苏海建集团，该公司为了适应现代立窑水泥生产的需要，设计产量为25t/h的预加水盘式成球机他们提出了以下几个技术要求：a． 产量为25t/h；b． 盘体工作面直径为3.6m； c. 结构紧凑，工作连续稳定； d. 节能、高效、环保 在杨晓红老师的指导下，首先进行方案论证通过讨论研究，最终确定采用可调盘高式 盘体、无动力刮刀系统、电机à皮带àZQ减速机à直齿轮副à成球盘的传动方式然后根据分析的结果，开始计算轴向力、扭矩以及功率分析拟定传动装置的运动简图，分配各级传动比，进而进行传动零件的结构进行设计和强度校核然后对盘式预加水成球机进行总体结构设计YQP36预加水盘式成球机改变了以往所成料球粒径大，料球耐压强度和孔隙率质量低的缺陷并且采用无动力刮刀系统，大大地节省了电耗和维护费用本课题新颖实用，在技术上有较大改进，具有较强的竞争力该预加水盘式成球机将具有很大的市场前景2 总体方案论证2.1料球的技术要求及对成球盘的技术调整分析高质量的料球与成球机的盘转速、盘倾角α、盘边高等的选择和调整有直接的关系。

转速高时，成球时间缩短，孔隙率提高，料球炸裂温度提高，爆球率低；转速太高将很难成球一般取12—13r/min适当增大α，可降低爆球率，一般取值在45°—55°范围内倾角的调整要与盘径、转速、边高综合考虑一般盘边高H=（0.14—0.19）D在不影响成球质量前提下，为降低爆球率，可适当减少边高2.2盘体的技术分析论证对于老式的盘边高偏高的盘边改进为盘边高为400—500mm的可调式的盘边，从而提高了成。
