摘要
以QZK2041型曲面高频筛为研究对象,通过分析高频筛筛网更换频繁的原因,对比弧形筛面和平面负倾角筛面的筛分效果、维护费用等主要指标,提出了应用平面负倾角筛面技术,以获得更优越的指标,同时降低维护费用。生产实践表明,在筛机主体结构不变的情况下,通过改造筛面、安装基层、调整前后支座高度的方法,实现了由弧形筛面到平面负倾角筛面的转换。
The study is made with the industrial QZK2041 high-frequency screening machine working with curved surface as the object.Following an analysis of the factors causing the frequent replacement of the meshwork of the machine,a comparison is made of the arcuate screen surface and the planar screen surface with negative inclination angle in terms of screening efficiency and maintenance costs.Through the analysis,it is proposed to use the latter screen surface for achieving a much improved screening performance and cutting down operating costs.Through technical transformation of screen deck support and readjustment of the height of both front and rear deck supports,the machine is made possible to switch to the use of plane screen surface with negative inclination angle without the need to change the main structure of the screening.
