AI Technical Summary

Technical Problem

Existing multi-stage vibrating screens are limited by the number of screening times, which cannot meet the requirements of proportional mixing of asphalt concrete aggregates. In addition, the equipment is bulky and has high maintenance costs.

Method used

It employs a rotating screening drum and a sliding, adjustable screen plate to achieve multi-stage screening by changing the overlap between the first and second screen holes. It is equipped with an electric telescopic rod to drive the screen plate to slide, and combines a discharge roller and an acoustic sensor to achieve automatic anti-clogging and multi-stage screening.

Benefits of technology

It solves the problem of the limitation of the number of screening boxes in grading screening, simplifies the device structure, reduces maintenance costs, improves production efficiency, and realizes proportional screening and automated control.

Abstract

本发明涉及沥青混凝土搅拌技术领域,公开了一种沥青混凝土搅拌振动筛,包括机体,机体的内部分别转动安装有筛分滚筒和间隙排料的排料辊,机体的内部滑动安装有网板,电动伸缩杆驱动网板直线往返移动,筛分滚筒的表面开设有若干个第一筛孔,网板的表面开设有若干个第二筛孔,网板的上表面与筛分滚筒的外表面滑动接触,当网板往返移动时,第二筛孔与第一筛孔错开重叠。该振动筛,采用旋转的筛分滚筒和可滑动调节位置的网板,通过改变第一筛孔和第二筛孔的重叠度的方法,使筛分滚筒具有多级筛分的功能,该设计解决了分级筛分受筛分箱数量的限制的问题,整体结构更加简洁,并大大缩小装置的体积,满足装置大型化或小型化的制造需求。
