摘要：目前，机立窑存在着很多的问题。这些初级阶段的立窑装备老化、不完善，工艺落后，消耗大，成本高，生产不稳定，产量质量低，它们正处于被淘汰的处境。因此，新型的JLY3809机立窑应运而生。而窑体及卸料装置的结构的好坏决定了此机立窑总体结构的好坏。JLY3809机立窑从以下方面对窑体及卸料装置方面进行了改造。1.大胆地的对原有机立窑进行了扩径改造，实现对立窑产量的大幅度提高。2.窑体保温直接影响机立窑产、质量，由于窑体保温不好，配煤增加，中部热量过剩，造成中部煅烧带延长，底火下移，影响机立窑煅烧，产量降低。故本机立窑在窑体内采用了绝热保温效果好的新型保温材料和浇注料。3. 选用新型窑体卸料结构。本机立窑不宜采用塔式结构，因为塔式结构不仅增加卸料部分高度，缩短窑的有效高度；而且随着窑径扩大，塔式窑中、边部卸料能力不均匀性越大，造成中部卸料速度远远大于边部卸料速度，必然造成底火拉深，中风不足，故我选择了卸料均匀性好的双曲面可换齿高效节能塔篦。经过对窑体及其卸料装置这一系列的结构和技术的改造，JLY3809机立窑的能耗变低，水泥产质量都得到了提高。 [资料来源：http://www.THINK58.com]

The design of the JLY3809 machine sign kiln (the kiln body and unload to anticipate a parts)
Abstract： Currently, the machine signs kiln exists a lot of questions. Such as material aging, not perfect, the craft falling behind, consuming greatly, high cost, unsteady production, and low output mass in these entry-level step’s sign kilns. They are placed in elimination of circumstances. Therefore, the JLY3809 machineses of the new model sign kiln emerge with the tide of the times. But the quality of the kiln body and unload apparatus comes to a decision of the quality of this machine signs kiln total structure. The kiln body and unloaded apparatus of the JLY3809 machineses sign kiln are carried on a reformation from the following aspects. 1.The diameter reformation is carried on to expand bravely in the original machine signed kiln. Then the kiln output of significant exaltation is realized. 2. The kiln body heat preservation will effect the production and quality directly. Because the kiln body heat preservation is not good. The mass of the coal will increase. The central calorific value will excess. These will result in that the central burning strap extends and the bed fire descends to move. 3.Unload to anticipate structure is chosen with the new kiln body. This machine's signing kiln should not adopt the tower type structure, because the tower type structure not only increases the division height, but also shortens the burden height of the kiln. And with the kiln diameter magnification, in the tower type kiln, the ability of anticipate asymmetry of the side unload unit is bigger, this results in that the speed of the central part of the unload apparatus is far larger than the speed of the side unit. It makes the bed fire tractive by all means deep and the middle wind suffers shortage. So energy tower with a good double of even curved faces is chosen, so that tooth can be changed. In addition, the energy tower is economical and efficient. Passed by a reformation of the kiln body and a series of structures and technologies of unload apparatus, Consumption of JLY3809 machineses' signing kiln can be become low, and the cement produces masses can get an exaltation.

1前言 
1.1 综述 
我国立窑生产技术的发展。大体经历了三个阶段：第一阶段是普通立窑阶段； 
第二阶段是机械化立窑阶段；第三阶段是从20世纪80年代中期开始推广节能改造新技术为起点的向着现代化立窑发展的阶段，目前正处于这个新的发展阶段。进入20世纪90年代以来，已经出现了一批全面推广应用各项技术，并实现了科学管理的现代化立窑企业，这些现代化的立窑企业主要的技术经济指标可与大型回转窑企业相媲美。 
1.2 设计依据及技术指标 
本课题来源于实际。随着建筑技术对水泥质量的要求更高，国家对环境要求更加严的形势发展，对现有的机立窑进行节能综合改造，使之成为一代新型机立窑，敢与在能耗，质量和环保等方面与普通旋窑竞争，是每一个立窑水泥工作者的历史使命。
