The mesh belt with the discharging plate returns to the screen flat. During the working process of the original small plane rotary screen, the screened material must pass through the two-layer screen surface, and the lower screen surface often screens out a large number of large and medium impurities that pass through the upper layer vertically. The cleaning mechanism is difficult to complete the cleaning work in time, thus causing the shutdown cleaning. As a result, the applicant has made a new improvement in the initial screening of the large amount of processing capacity. The mesh belt with the discharging tray plate is returned to the screen flat, which comprises a screen frame (1) which is hoisted in the screen box (2) and a group of metal sieve plates arranged in a conveyor belt. The conveyor belt is connected with a driving motor (4). A screen box is arranged between the upper screen surface (3) of the conveyor belt and the lower screen surface (5). The connecting box is connected with a flat return motion mechanism (6), and the sieve box is connected with a flat return motion mechanism (7). This application is used for handling food removal equipment with a throughput of more than 100 tons per hour.
【技术实现步骤摘要】
带出料淌板的网带平回筛
:本技术提供一种粮食机械中的分选除杂设备,特别是一种处理量每小时100吨以上的,带出料淌板的网带平回筛。
技术介绍
:原有普通的小型平面回转筛工作过程中在进料口集中喂入的物料,在筛体圆运动作用下,平面回转筛均匀地分布在整个筛面宽度上,并产生自动分级。从而使料层下面粒度较小的物料迅速过筛,而上面粒度较大的物料则向出料端运动。传统的网带初清筛虽然产量大,但由于只能直线运动,筛面和粮食没有相互运动容易堵塞,只能处理大杂。如果缩小网眼,小颗粒粮食和杂质很容易镶嵌在网眼中无法去除,使得有效筛分面积减小,导致筛理效果不理想。本技术有效的解决了这个问题。传统的网带筛,穿过上层筛面的物质,直接下落并通过下层筛面,筛余物前行,粮食扩散程度差,经过很短的路程,就不再具有筛理性能,所以传统的网带筛长度都比较短,一般用来清除较大的杂质,没有清除中杂和小杂,所以只是初清。并且由于传统的网带筛没有扩散功能,加入量大时非常容易堵塞。千网打鱼,网网都有鱼,筛分除杂也是如此,垂直穿过上层筛面的大中杂总会有的,网带筛都有上下2层,当这些的大中杂被下层筛面拦截后会造成网带筛堵塞 ...
