1、低噪声高频振动筛结构设计摘要现在中国在各种选煤厂运用的所有机器设备里,振动筛是出现麻烦次数比较多、维护工作量较大的机器之一。很多问题着重体现为筛箱出现断梁、开裂现象,采用稀油进行润滑的箱式振动器漏油、齿轮打齿、轴承温升过高、异常声响大等,还伴随传动带跳带断裂等问题。这类故障直接导致振动筛的工作寿命,极大影响了生产运作。而本次设计的振动筛为GPS1025型高频振动筛,该系列振动筛主要用于煤炭行业中物料分级、脱水、脱泥、脱介等作业。其工作可靠,筛分效率高,但设备自身较重。设计分析论述了设计方案,包括振动筛的分类与特点和设计方案的确定;对煤泥进行运动学上的研究,对振动筛的动力学参数进行考虑和计算,合
2、理设计振动筛的构造大小;电动机的应用与检查;进行了主要构件的设计与计算。绘制了 GPS1025高频振动筛的总装配图及主要零件图;然后对于机器维护、应用、润滑、密封还有噪声方面的降低等情况,进行了大概的介绍,最后对于振动筛环保性能还有实际应用的经济效益进行讲述。关键词:振动筛;激振器;高频振动筛;低噪声ABSTRACTNow, in all the machinery and equipment that China USES in various coalpreparation plants, vibrating screen is one of the machines that have
3、more trouble andmaintain a larger workload. Appear many problems mainly embodied in screen boxbeam, cracking phenomenon, the thin oil lubrication for box type vibrator oil leakage,gear cutting, large bearing high temperature, abnormal sound, etc., also with jumpproblems such as fracture belt. This k
4、ind of fault leads directly to the working life ofthe vibrating screen, which greatly affects the production operation. The vibratingscreen of this design is the GPS 1025 high frequency vibrating screen, which is mainlyused in the coal industry for material classification, dehydration, desilting, de
5、siccationand so on. The work is reliable, the screening efficiency is high, but the equipmentitself is heavier The design analysis discusses the design scheme, including theclassification and characteristics of the vibrating screen and the determination of thedesign scheme; The kinematics of coal sl
6、ime is studied, the dynamic parameters ofvibrating screen are considered and calculated, and the structure size of the vibratingscreen is reasonably designed. Application and inspection of motor; The design andcalculation of main components are carried out. The general assembly drawing andmain parts
7、 drawing of the GPS 1025 high frequency vibrating screen are drawn. Then,the paper introduces the maintenance, application, lubrication and sealing of themachine, and finally explains the environmental performance of the vibrating screenand the economic benefits of practical application.Key words: s
