文档介绍：沙石振动筛的设计
摘要
十六大明确提出,我国在新世纪头20年经济建设的主要任务之一,是基本实现工业化,并郑重提出“走新型工业化道路”。可是在我省大多数沙石材料厂的沙石筛选过程还是走着最原始的人工运作,工具简单,劳动强度大的老路。本设计正是我们在了解了家乡大部分沙石场的实际情况后,运用我们所学知识为家乡的中小规模的沙石场设计的一种筛分砂石的振动筛。
本设计的振动筛为自同步双振动电机驱动的,其特点是结构简单、安装方便、成本低、容易操作及维护等。其筛箱为板梁铆焊组合结构,由主副侧板、管梁、入料挡板、出料板、筛板等组成,侧板选用低合金压力容器钢板,强度高、可焊性好,周边折弯,并在振动方向及沿纵向连接多根角钢,使侧板刚度大大增强,有利于强度的提高和噪音的降低。管梁由法兰盘、无缝钢管、加强槽钢等组成,重量轻、强度大,便于制造安装,具有互换性。加强槽钢上有T形孔,使用T形螺栓,便于筛板的安装维护,消除U形螺栓对管梁的磨损。工作原理:两台振动电机的型号相同,可以产生一种组合的直线振动。这种振动可以使输送槽体中的物料运动,并与筛面发生碰撞,使小于筛孔的物料透过,从而实现物料的几何分级,实现筛分。总体方案为:采用普通筛分法,振动形式为共振,运动轨迹为直线运动,激振方式为惯性式,隔振方式为一级隔振,隔振弹簧为金属螺旋式隔振弹簧。

The design of gravel shaker
Abstract
Congress made it clear that in the new century, China's first 20 years of economic development one of the main tasks is the basic realization of industrialization, and solemnly to "take a new road to industrialization." However, in our province the majority of gravel sand and gravel plant materials selection process is the most primitive artificial walked to operate simple tools, the old labor-intensive. The design is exactly what we learned about the home in the sand most of the actual market situation, we have learned to use his knowledge of small and medium-sized gravel field design of a shaker screen sand and gravel.
This topic shaker for self-synchronizing pair vibration motor-driven, Its characteristic is the structure simple, the installs convenient, the cost low, is easy to operate and the maintenance and so on. It sieves the box is board crossbeam riveting hitch welds built-up section, By host vice- side bar, Hollow beam, Enters the material back plate, Leaves material board, Sieves board and so position, The side bar selects the low-alloy pressure vessel steel plate, The intensity is high, The weldability is good, Peripheral knee bend, And in the vibration direction and along longitudinal connects themulti- roots angle steel, Causes the side bar rigidity big enhancement, Is advantageous to the intensity enhancement and noise reducing.
