排渣分离机

一、设备概述
废纸处理过程中会产生大量尾渣，这些尾渣弃之可惜，回收又比较困难。排渣分离机专为处理纤维分离机、复式纤维分离机、压力筛等设备的尾渣而特殊设计，能有效分离纤维与杂质，并使纤维回收率达到70%左右，减少纤维流失。
排渣分离机常压密闭操作，连续排渣，没有糊筛、堵浆和浆水飞溅现象，无振动、噪声，不必专人看管，分选出的杂质浓度达10%—15%，可不经处理直接作为垃圾废弃。排渣分离机是目前较先进的尾渣处理设备，与压力式尾渣筛相比，可简化系统流程，节省动力消耗，与振框平筛相比，可大幅提高分选效率，优化操作环境。

二、结构及原理
排渣分离机的上半部是涡旋室，下半部是半圆形的筛选区，内部装有高转回转的转子，转子上焊有轴向的扫浆叶片和螺旋状交替排列的分选刀片。浆料从进浆口进入后，高速转子对尾渣进行拍、刮、撕、剥的综合作用，先并将尾渣抛向涡旋室，然后再撒落到筛选区，完成纤维与杂质的分离过程，同时转子上方的喷嘴不断喷水，对尾渣进行稀释和淘洗，并冲洗转子及筛板。经过一次次循环分选，分离出的好纤维通过筛孔后从筛板下方的出浆口排走，剥离下来的塑料片等杂质经冲洗后从排渣斗排出，作为垃圾废弃。

排渣分离机主要由上盖、转子、筛板、底座和传动装置等组成。

1．上盖通过法兰与底座相联，内腔呈∩型，翻开上盖，可对分选机进行检查、清洗或更换筛板作业。为了淘洗尾渣，上盖两侧各装有一排喷水管。

2．转子是一条特殊结构的空心轴，上面焊有轴向的扫浆叶片和螺旋状交替排列的分选刀片。扫浆叶片和分选刀片用于拍打、撕剥尾渣，将尾渣抛向涡旋室，并有效清理筛板，保持筛孔畅通。

3．筛板呈半圆形，由不锈钢板制成，筛板有多种规格的筛孔尺寸，用户可根据原料情况及使用条件进行选择。筛板采用钻孔、去毛刺、抛光等工艺处理，达到光洁、光滑、不挂浆的技术要求。

4．底座用来安装筛板、上盖、转子等部件，通过筛孔的良浆从底座内的出浆口排走，分离出来的杂质从底座尾部的排渣斗排出。

Reject Sorter is an Impurity Cleaning Equipment which is specially designed for processing the tailings from fiber separator, duplex fiber separator, pressure screen and other devices. It can effectively separate the fiber and impurities, and make the fiber recovery up to about 70% and reduce the fiber loss. Reject Sorter is operated under an ordinary pressure and closed condition, and it can continuously slag, no sticking screen, clogging pulp and pulp splashing. Meanwhile, no vibration and noise can be observed. It is not necessary to be supervised by a specified person, and the concentration of the impurities selected can be up to 10%-15%, which can directly be discarded as the waste without processing. Reject Sorter is the more advanced equipment for processing the tailings at present. Compared with the pressure-type tailings screen, it can simplify the system process and save power consumption; compared with vibration frame flat screen, it can significantly improve the screening efficiency, optimize the operation environment.

Features of Reject Sorter:

1. Used for processing the light impurities tailings, and have defibering, screening and rejecting functions.

2. Less fiber loss, lower power consumption, easier operation and better working environment.
