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一点小改动,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,且铸钢内含有一部分合金元素,又耐氧化不易变形等,故使用寿命一般比Q235钢至少高2~3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。

Abstract:This subject designs the charging and hooding parts of JLY3809 kiln. At present, JLY3809 mechanical upright kiln is a new emerging large diameter kiln. Because many corollary equipment have not been improved and still adopt conventional technology ,so the benefits with the new kiln can not been realized. In this subject we have designed the new charging device and hooding parts of kiln. The supporting and charge spreading have been improved ,too. The production practice indicates that the propping up equipment after transformation transmits steadily. Also the lubrication and the overhaul is convenient; after the transformation cotton material has promoted its altitude. The material cant be easily blocked, which reduces the labor intensity looks at the hot work, the cotton material is not easily corroded, reduced the repair and replacement; a point of small modification is also made in the elevating equipment aspect, adding in anti-turning equipment, after the transformation, the hooding parts of kiln is advantageous for the transportation, the hoisting and lower part which rusts is easily away possible alone to be replaced and disassembled. The cast steel is thermostabler than the ordinary Q235 steel, also the cast steel includes part of alloying elements, the oxidation and can not  be easily distorted and so on. The service life of it is generally 2~3 double higher than Q235 ,moreover in the design there also involves the settling pocket and the new dust catcher shaping, reduced the resources waste. Enhanced the cement production efficiency, reduced greatly the environment pollution made by mechanical upright kiln.
