【摘要】：城市生活垃圾转运站在当前城市卫生改善方面意义重大,而垂直式垃圾压缩机是转运站中使用最广泛的一种装置。现有的垂直式垃圾压缩机普遍存在质量重、体积大、结构不合理、房屋造价高,安全系数低等问题。本文结合同类垃圾中转站压缩设备的优点并联系实习企业生产实际情况,对现有垃圾中转站压缩设备进行改进,设计了一种新型垂直式垃圾压缩机。主要工作内容如下:1、在设计上主要改进了原有垃圾压缩机的压头布置的方式和四立柱支架。布置方式的改进缩短了压缩油缸行程,提高了工作效率,降低了整机质量;四立柱支架的改进,节省了材料,降低了整机高度,使得垃圾站房屋建筑费用降低。本文同时对压缩机的箱体、推板、导向轮组等机构进行改进,并设计了废液排放装置。2、对新型垂直式垃圾压缩机压头支架部分进行了有限元强度分析,对其应力集中区域进行结构强化,优化后的支架能够满足材料的许用应力要求。另外,由于压缩机构受反复载荷作用,故对该机构进行了疲劳可靠性分析,确定其使用寿命约为5年。3、设计了新型垂直式垃圾压缩机液压系统,并对其进行仿真分析。设计系统与以往相比,节省了压缩时间,提高了压缩效率,减少了能量损耗。4、建立了新型垂直式垃圾压缩机垃圾压缩数学模型,通过系统仿真与实验分析,验证了数学模型的准确性,分析结果比较符合实际情况。
[Abstract]:The municipal solid waste transfer station is of great significance in the improvement of urban sanitation at present, and the vertical garbage compressor is the most widely used device in the transfer station. The structure is unreasonable, the building cost is high, the safety factor is low, and so on. This paper combines the advantages of the same kind of garbage transfer station compression equipment and the actual production situation of the practice enterprise to improve the existing refuse transfer station compression equipment. A new type of vertical garbage compressor is designed. The main work is as follows: 1. In the design, the pressure head arrangement of the original garbage compressor and the support of the four columns are mainly improved. The improvement of the arrangement mode shortens the stroke of the compressed cylinder. It improves the working efficiency and reduces the quality of the whole machine, the improvement of the four-pillar support saves the material, reduces the height of the whole machine, and reduces the building cost of the garbage station. The guide wheel group and other mechanisms are improved, and the waste liquid discharge device .2is designed. The finite element strength analysis of the pressure head support of the new vertical garbage compressor is carried out, and the stress concentration area is strengthened. The optimized support can meet the allowable stress requirement of the material. In addition, the fatigue reliability of the compression mechanism is analyzed because of the repeated load. The service life of the system is about 5 years. The hydraulic system of the new vertical garbage compressor is designed and simulated. Compared with the past, the design system saves the compression time and improves the compression efficiency. A new type of vertical garbage compressor garbage compression mathematical model is established by reducing energy loss. The accuracy of the mathematical model is verified by system simulation and experimental analysis. The results of the analysis are in line with the actual situation.
