型砂处理机筛分机构设计
摘要
本设计为型砂处理机筛分机构的设计,主要研究内容:激振器的机构设计;筛箱的结构设计;筛网的结构设计。
本设计是由激振器,参考圆振动筛的相关参数,初步确定凸轮轴的转速,从而确定线速度、筛箱的大小、筛网的孔径等相关数据。在保证生产率和筛分粒度的前提下完成总体结构的设计,然后根据总体结构,从而确定本设计的筛分机各个主要零部件的设计。
在主要零部件的设计中,主要包括运动参数的选择、振动工艺参数的计算、动力学分析和参数计算、电动机的选择、筛箱的设计、激振器轴承的选用及校核等,其中最重要的就是动力学分析和参数计算。凸轮轴采用铸钢做成,并使用新型材质以提高其的耐磨性和利用率。
本设计整体圆振动筛基础上更进一步提高了其筛分性能,结构简单、重量轻、外形尺寸小、设备费用低、运转安全、操作方便、便于维修和管理。

Sand sieving mechanism design of processor
Abstract
The design for the design of molding sand sieving mechanism of the processor, main research contents: mechanism design vibrator sieve box; structure design; structure design of the screen.
The design consists of a vibration exciter, referring to the related parameters of circular vibration sieve, preliminary determine the cam shaft speed, so as to determine the line speed, screen size, screen size and other related data. In ensuring pletion of the overall structure of the design condition of productivity and screening granularity, then according to the overall structure, so as to determine the design of main parts of each of the design of the screen.
The design of the ponents, including the motion parameters, vibration parameters calculation, dynamic analysis and parameter calculation, the choice of motor, the design of screen box, vibrator bearing selection and checking calculation, in which the most important is the dynamic analysis and parameter. Cam shaft made by casting, and the use of new materials to improve their wear resistance and utilization.
The design of the whole circular vibrating screen based on further improving its crushing performance, simple structure, light weight, small size, low cost of equipment, operation safety, convenient operation, easy to repair and management.
Keywords: sieve; sieving ; shaker ; vibration; exciter
