YQP36預加水盤式成球機設計
摘 要：為了滿足現(xiàn)代機立窯水泥生產過程中預加水成球的技術要求，發(fā)展第六代預加水盤式成球機，從而保證料球的粒徑均勻性、高強度、高孔隙率和高產量，提高水泥的煅燒質量和產量，本課題設計了YQP36預加水盤式成球機。根據(jù)最新的技術要求對 YQP36預加水盤式成球機的結構、傳動系統(tǒng)和刮刀系統(tǒng)進行了改進設計。本次設計采用理論設計和經驗設計相結合的方法，在通過類比設計保證機架與支架的支承強度的基礎上優(yōu)化了傳動系統(tǒng)和刮刀系統(tǒng)。參考實踐生產中的一些改進經驗，首先進行了總體方案的論證；然后根據(jù)分析的結果來計算各傳動軸的軸向力、扭矩以及功率，并校核了軸和螺栓的強度，從而選擇電機和減速機型號及設計其他相關零部件。根據(jù)已確定的部件參數(shù)分析擬定傳動裝置的運動簡圖，分配各級傳動比，確定了傳動零件的結構；接著對 YQP36預加水盤式成球機的潤滑和密封方式加以確定；最后對預加水盤式成球機的維護修理加以說明，從而完成預加水盤式成球機的總體結構設計。此次設計本著高產量、高質量成球，穩(wěn)定運轉的原則，實現(xiàn)了現(xiàn)代預加水盤式成球的節(jié)能、經濟、環(huán)保、可擴展的目的。

The Design of YQP36 Disc Prewatering Pelletizer
Abstract: In order to satisfy the technical requirement of prewatering pelletizing in the process of cement production with modern kiln and develop the sixth generation of prewatering pelletizer, the topic which is designed is YQP36 Disc Prewatering Pelletizer. 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.
