摘要城市生活垃圾产量的增长，成分日趋复杂，危害也日益显露和突出，这种危害不是单方面的因素，而是全方面的因素所引起的，如生活水平质量的提高，消费观的改变，人们总体环保意识的欠缺，政府担负太重而导致资金的欠缺等等，通过对国外生活垃圾处理方式研究，吸收他们的有效经验，合理的设计出本方案，使生活垃圾变废为宝，创可持续发展新理念。47272

    本方案主要由带式输送机、水洗筒、卷扬机通过合理的装配，组合成生活垃圾处理的水洗部件组。带式输送机的核心部件有输送带、托辊，水洗筒的主要部件有阀、泵、筒体，卷扬机的核心部件有定滑轮组、电机、减速器。通过皮带送料卸料、水洗筒水洗、卷扬机提升送料卸料等步骤，完成了对生活垃圾处理前的水洗工作。

Abstract With the growth of output of city life trash and the more complicated composition , the harm is increasingly highlight. The harm is not duo to the unilateral factor, but all aspects of factors, such as the improved quality of living standards  ,the changes of consumption concept , people's generally lack of awareness of environmental protection, the government's burden 5s too heavy and the lack of funds and so on. Through the learning of foreign garbage disposal, absorbing their experiences, i design  the resonale programme to let the garbage waste to treasure and take a new concept of sustainable development.

   The program is mainly composed of a belt conveyer, washing cylinder, a windlass ，and through reasonable assembly they are combined into a garbage treatment of the washing components.The core components of the belt conveyor are conveyor belt, and roller. Then the core components of washing cylinder are valve, pump and cylinder. And the core components of  hoist are the fixed pulley, motor,and reducer. With the steps of the belt's feeding 、unloading,the washing cylinder's washing,the windlass's feeding 、unloading , it completed the washing work before garbage disposal .

Keywords:city life garbage;belt conveyor;washing barrel; windlass
