毕业设计论文JLY3809机立窑(加料及窑罩部件)设计说明书

摘要：本课题完成了JLY3809机立窑(加料及窑罩部件)设计。JLY3809机立窑是目前新兴的扩的直径窑，但在很多配套设备上还是沿用扩径前的技术设备，使得虽然进行了改造，但是相关设备未能得到改进，未能体现出新窑的优势。本次设计了新型的加料装置和窑罩。新型加料装置对支承装置和布料器做了改进，生产实践表明支撑装置经过改造后，传动平稳，且润滑和检修方便;改造后的布料器提升了高度，不易堵料，减轻看火工的劳动强度，布料器不易腐蚀，减少维修更换费用;在升降装置方面也做了-点小改动，增加了防扭器.改造后的窑罩便于运输，吊装和易于锈蚀的下部可以单独更换和拆卸。铸钢比普通的Q235钢耐高温，且铸钢内含有-部分合金元素，又耐氧化不易变形等，故使用寿命-般比Q235钢至少高23倍。设计中还涉及到沉降室和新型收尘器的选型，减少了资源的浪费，提高了水泥的生产效率，大大减少了机立
窑对周围环境的污染。
