3090型直线振动筛结构设计
摘要
直线振动筛可能普通人没有接触过，也不怎么了解，但是对于在矿场工作过的人来说那肯定是非常熟悉的，因为在任何矿场都离不开对开采矿物的筛选，常用的筛选工具则是振动筛了，而直线振动筛则是众多筛选工具中最为常用的一种，它的结构形式简单、性能稳定、型号多样适用于各种大中小型矿场，随着机械化程度的不断提高，对于筛分容量的要求越来越大，筛机技术要求也越来越高。
其他还有两种振动筛也有不少的应用，他们分别是利用圆周运动来分离矿石的圆运动振动筛和利用共振原理来实现矿物筛选的共振筛，我们这里主要研究的是直线振动筛，另外两种振动筛我们就不多做描述了。直线振动筛不仅仅可以应用于筛煤矿，将小颗粒筛选下来，将大块煤矿筛出，进行大煤块与小煤块的分离工作；振动筛可以用于豆芽脱皮，通过不停的振动，实现豆芽与豆芽皮的自动分离，操作简单生产效率高；此外振动筛还可以根据孔的大小不同来筛选不同规格的网钉；农业生产中可以用振动筛筛选玉米、黄豆、小麦、花椒等，他们的工作原理基本相同，只是筛网种类不同，最终目的是达到两种介质的分离。目前人们通过对振动筛的不断改进，不断研发与更新，已经发明了陶瓷振动筛和超声波振动筛，能达到很高的分筛精度（200-600目），并且可以24小时连续不间断的工作。
虽然目前我国振动筛水平在制造加工工艺等方面已经取得了不错的成果但是我们的缺点和不足也同样存在着，这就需要我们来根据生产的需求对现有产品不断改进、更新，核心技术上不断开发、研究与深入，自主研发，做自己的产品。只有掌握其真正的核心技术，才能成为技术的主导者，才能在日益严峻的采矿工具市场中站稳脚跟与时俱进从而不被淘汰，振动筛的发展不但会对分离技术带来巨大技术还会带动国民经济的发关键词：筛癣大功率双电机直线振动筛、电同步、Solidworks三维建模软件、整体构造的计算与制作
Abstract
Linear vibrating screen may have no contact with ordinary people, do not know how, but for the people who worked in the mines that must be very familiar with, because in any field cannot do without screening on mining, screening tools commonly used is the linear vibrating screen, vibrating screen is large screen one of the most commonly used tools, its structure is simple, stable performance, suitable for various types of large and small mines, along with the increasing degree of mechanization, the requirement for screening capacity is more and more big screen machine, the technical requirements of increasingly high.
There are two kinds of vibration sieve also has many applications, they are circular motion to separate vibration sieve and ore utilization of circular motion using resonance principle to realize the resonance sieve screening mineral, here we mainly study the linear vibrating screen, the other two vibrating screen we do not describe. Linear vibrating screen can not only be applied to sieve coal mine, the small particle filtering down, to screen out the large coal mine, coal separation large and small coal; can be used for peeling sprouts shaker, through continuous vibration, automatic separation of bean and bean sprouts skin, simple operation and high production efficiency; in addition, vibration sieve according to the size of the hole is different to screen different net nail; agricultural production of corn, soybeans, wheat can be screened, the pepper shaker, its working principle is basically the same, but different types of screen, the ultimate goal is to achieve the separation of two media. At present people through the continuous improvement of the vibrating screen, development and renewal, has invented the ceramic vibrating screen and ultrasonic vibration sieve, can achieve high screening precision (200-600), and 24 hours of continuous work.
Although China's vibrating screen level in the manufacturing process and has achieved good results but our shortcomings also exist, which we need to according to the production requirements of existing products continue to improve and update the core technology research and development, in-depth, independent research and development, to do their own products. Only by grasping the real core technology, to become a leader in technology, in order to gain a firm foothold in the times of increasingly severe market mining tools so as not to be eliminated, the development of vibrating screen will not only bring huge technology for separation technology will promote the development of the national economy, so the production and development of production to meet the new demand with a vibration sieve broad market prospects.
Key words: screening, high-power dual motor linear vibration screen, electrical synchronous, Solidworks three-dimensional modeling software, the overall structure of the calculation and production
