打浆机和圆柱磨浆机的相关知识
beater and disk pulper

自打浆机发明使用后经过不断的改进和完善
Since the invention and continuous improvement of the beater

一直使用到现在
we have been using it up to now

虽然打浆机与其它打浆设备相比较
Comparing with other beating equipment

具有消耗功率大
the beater has the characteristics of high power consumption

占地面积大及间歇作业等特点
large floor area and batch operation

但是由于它能处理各种不同性质的纸浆
However, it can handle a variety of different properties of pulp

并且通过运行条件的改变
and can obtain different pulp characteristics required

可以获得不同要求的纸浆特性

因此在现今和今后
Therefore, at present and in the future

国内外造纸厂中某些情况下仍有所使用
it can still be used in some cases of domestic and foreign paper mills

例如对处理棉、麻、硬布以及半化学浆
such as specialized technology production line

或小工厂专门工艺的生产线

也就是一些特种纸的生产线
which is also a special paper production line

另一方面
In another aspect

打浆机是最先出现的打浆设备
the beater is the earliest equipment

其它类型的打浆设备

打浆机发明至今
Although many improvements have been made

虽然经历了很多的改进

但其结构的主要部分仍然保持了原有的构造
the main parts of its structure remain the original structure

打浆机主要由浆槽、底刀、飞刀辊

与底刀之间的间隙时
between the rotary knife roll and the bed knife

受到飞刀与底刀的
it is subjected to the mechanical action

剪切、碾磨等机械作用

当纸浆需要洗涤时
When the pulp needs washing

可放下洗鼓并打开喷水管冲洗
you can put down the washing drum and open the spray pipe to wash

接下来我们一起学习圆柱磨浆机
Next we learn about disk pulper

双向流式圆柱式磨浆机的
The basic working principle

基本工作原理为
of double flow disk pulper is as follows

利用纸浆进浆压力
by using pulp feed pressure

从主轴的空心段一侧进浆口
the pulp is fed from one side of the hollow section of the main shaft

供料至圆柱转子中部的孔盘区
to the hole plate area in the middle of the cylinder rotor

利用孔盘区产生的离心力和纸浆进浆压力
using centrifugal force and pulp feed pressure

使纸浆经过孔盘区出浆槽口
from the hole plate area

均匀地输送到
the pulp is transported through pulp outlet

磨浆区的左右两个区域
to the left and right regions of the pulping area evenly

在圆柱式的两个反向流动的磨浆区
The pulp is fully grinded at pulping area

进行充分研磨
of the disk pulper with the two reverse flow

该机同单向流式圆柱式磨浆机相比
Comparing with the single flow cylindrical grinders

具有如下特点
this machine has the following characteristics

首先，浆料输送
first, pulp transport

和磨浆过程中的操作彼此独立
and the operation of the pulping are independent of each other

其次，由于纤维层数较多
secondly, because of the large number of fiber layers

对单根纤维的处理几率增大
the processing probability of the single fiber increased

较好地发挥了纤维强度的潜能
which brings a better performance for the potential of the fiber strength

根据纤维原料的不同
Depending on the specie of fiber materials

磨浆单位负荷大约提高10％～20％
the unit load of the pulp is increased by about 10% ~ 20%

由于在整个磨浆区的磨浆速度不变
not only the energy consumption of the pulping is reduced

不仅降低了磨浆能耗
but also the pulping quality is improved

而且提高了磨浆质量
because the pulping speed in the whole pulping area is unchanged

还有就是空载动力消耗大幅度降低
There is significant reduction in the no-load power consumption

可以降低45％
which can be reduced by 45%

与锥形磨浆机和双圆盘磨浆机相比

and improve the pulping quality

最后就是设备易操作性好，且易于维修
Finally, the equipment is easy to operate and maintain

从某种意义上说可以把圆柱磨浆机视为
