9.5 中、高浓盘磨机及疏解设备在线视频

这一节我们将一起探讨一下
In this section, we'll discuss

中高浓盘磨机
the medium and high consistency disc pulper together

在漂白部分及纸浆流送和压力容器中
We have introduced

我们跟大家介绍了工程意义上
the division of pulp consistency

纸浆浓度的划分
in the bleaching and flow

不知道大家是否还记得
of pulp and pressure vessel

一般小于7%浆浓的我们称为低浓纸浆
With less than 7% we call it low consistency pulp

7%-15%浆浓的为中浓纸浆
with 7%-15%, we call it medium consistency pulp

大于15%浆浓的为高浓纸浆
with more than 15% we call it high consistency pulp

与普遍工程意义的浓度划分不同
It is different from the consistency of general engineering

在造纸界还有一种称呼习惯
there is also one kind of habit in the paper industry

就是相对于原有传统的工艺条件的
that is, the difference between low consistency and high consistency

低浓和高浓之分
compared with the original traditional process conditions

例如高浓筛选
such as high consistency screening

可能绝对的浓度并不高
the absolute consistency may not be high

只是相对于传统的筛选工艺浓度的提高
but the consistency is higher than the traditional screening process

对于打浆也是如此
This is also true for beating

由于大部分生产一直采用低浓打浆
Low consistency beating is applied for most production

所以人们在生产中习惯把打浆浓度在5-8%时
people always call 5-8%

就成称为中浓打浆或高浓打浆
as medium or high consistency

实际上这个浓度只是工程意义上的
This is actually the critical consistency for low

低浓纸浆和中浓纸浆的临界浓度
and medium consistency in engineering sense

达到这个浓度
Reaching this consistency

传统的低浓浆泵输送已经比较困难
it is always difficult for the traditional low consistency pump transportation

因为浆浓与输送有很大的关系
There is a great relationship between pulp consistency and transportation

在这里我还是以工程意义上的
I still use medium and high

中浓和高浓来表述
in the engineering sense

中、高浓打浆Medium and high consistency beating

可以明显的提高打浆的质量
can obviously improve the quality of beating

主要是由于中、高浓打浆时
The fibers plays as the cushion on the tooth surfaces

浆料纤维在齿面和齿缘形成垫层
and the tooth edges which reduces the cutting

减少了切断作用
and increases fibrillation

增加分丝帚化作用
during medium and high consistency beating

中、高浓打浆可以降低能耗
Medium and high consistency beating can reduce energy consumption

主要是中、高浓打浆时浆料纤维之间
mainly due to the increase

的摩擦力作用增加
in friction between pulp fibers

减少磨盘相互间的接触
the decrease of contact between grinding discs

并且产量增加
and the increase in production

从而使打浆的单位电耗降低
Thus the unit power consumption of beating is reduced

中、高浓度盘磨机
Medium and High consistency disc pulper

是由一般的盘磨机发展而来的
is developed from the general disc pulper

主要有卧式单盘磨机和双动盘磨机
mainly horizontal single disc and double-action disc

也有立式单盘磨机
there is also vertical single disc pulper

这是三种类型的
This is the schematic diagram

中浓度盘磨机的示意图
of three types of medium consistency disc pulper

使用得广泛的是卧式中浓度盘磨机
The horizontal medium consistency disc pulper is widely used

其中卧式单盘磨机用得尤为普遍
especially the horizontal single disc pulper

图中所示是高浓度盘磨机的
The spiral and disk cavity structure

螺旋及盘腔结构
of the high consistency disc pulper is shown in the figure

总的来说
Generally speaking

中高浓度的盘磨机的结构
the structure of the medium and high consistency disc pulper

具有如下的特点
has the following characteristics

第一，中高浓盘磨机
the first, compared with the common disc pulper

与通常的盘磨机比较
the medium and high consistency disc pulper

要求整体结构强固，刚性大
requires the whole structure to be strong and rigid

第二，中高浓盘磨机要求
the second, the medium and high consistency disc pulper requires

几何形状匀称，热影响小
the geometric shape to be symmetrical and the heat effect is small

第三，中高浓盘磨机
the third, the medium and high consistency disc pulper

要求盘径大
requires the disk diameter to be large

还有就是磨盘的齿纹面需要有较大的梯度
and the tooth grain surface of the disk requires a larger gradient

对于高浓打浆
For high consistency beating

还有一种圆柱形高浓打浆机
there is also one kind of cylindrical high consistency beater

圆柱形高浓打浆机的打浆全过程
The whole beating process of cylindrical high consistency beater

是低浓度进浆、高浓度打浆
is low consistency feeding, high consistency beating

一般可以达到20%以上的浓度
which can reach more than 20%

低浓度出浆的过程
low consistency discharging

所以，圆柱形高浓打浆机
Therefore, the cylindrical high consistency beater

不需要另外配用高浓进浆装置
does not need to use other high consistency feeding device

使流程简化
so that the process is simplified

由于时间关系
We will leave it here because our time is limited

这里就不展开讲了，大家可以去看书
You can read from the textbook

以上就是中高浓
The above is the relevant knowledge

盘磨机的相关知识
of the medium and high consistency disc pulper

下面我给大家简要介绍一下疏解设备
Next, I'll give you a brief introduction on the deflaker

疏解设备的作用
The function of the deflaker

就是在不切断损伤纤维
is to make the fiber fully defiber

不降低纤维强度的前提下
without cutting off or damage the fiber

使纤维充分地疏解分散
or reducing the strength of the fiber

疏解设备是在各类打浆设备发展的基础上
Based on the development of all kinds of pulping equipment

根据生产需要
the deflaker equipment is separated and perfected

及打浆设备的功能趋向专门化时
according to the need of production

分离、完善出来的
and the function of the pulping equipment tends to be specialized

它的核心机构原理
and its core mechanism is also different

也与打浆设备有不同之处
from that of the pulping equipment

疏解的目标
The goal of the defibering

是将纤维团或纸片
is to separate the fiber agglomerate or paper

离解成单根的、润湿的纤维
into single, wet fibers

有时，当工厂制浆设备能力
Sometimes, when the capacity of the pulping equipment

受到限制时
in the factory is limited

采用疏解机
the deflaker machine is used

来增加制浆机械的碎浆能力
to increase the pulping capacity of the pulping machine

为了避免硬杂物碰坏齿环或齿盘
To avoid the damage of ring gear or disc caused by hard debris

应在高频疏解机前
screening and purification equipment should be equipped

配置筛选净化设备对浆料进行处理
in front of the high-frequency deflaker to treat the pulp

高频疏解机是一种疏解设备
High-frequency deflaker is a kind of defibering equipment

它是由一个高速回转的转盘
It is composed of a high-speed rotating disk

和一个固定的定盘组成
and a fixed disk

通常使用的高频疏解机
The commonly used high-frequency deflaker

分中间咬合型、平行板型和圆锥型
is divided into middle bite type, parallel plate type and cone type

图中所示的就是
The high-frequency deflaker

圆盘式中间咬合型的高频疏解机
is shown in the picture

圆盘式高频疏解机转子和定子
There are 3 row tooth rings with concentric circle on the rotor and stator

各有同心圆的三排齿环
of the disc-type high-frequency deflaker

转子齿环与定子齿环相互啮合
and the rotor tooth ring and stator tooth ring are meshed with each other

组成了疏解区
forming the defibering zone

齿环上的齿数
The number of teeth on the tooth ring

自内向外逐渐增加
increases gradually from the inside to outside

而齿间间隙则逐渐减小
while the clearance between the teeth decreases gradually

运行时
During operation

浆流进入齿盘中心
the pulp flows into the center of the tooth disk

通过转盘和定盘的齿间间隙
and flows radially through the gap

向外作径向流动
between the rotary disc and the fixed disk

浆流被逐次分散成更细的浆流
the pulp flow is gradually dispersed into a finer pulp flow

并形成较高的圆周运动
and forms a higher circular motion

受到的机械冲击力也就越来越大
and the mechanical impact force becomes larger and larger

在高频率的机械和水力的作用下
Under the action of high-frequency mechanical and hydraulic power

浆料中的纤维束或碎纸片
the fiber bundles or paper fragments in the slurry

被分散成单根纤维
are dispersed into a single fiber

处理浆料的浓度一般为3～5%
The treated pulp consistency is generally 3-5%

这是平行板型高频疏解机
This is a parallel plate type high frequency deflaker

在转盘和定盘上都均匀分布有通孔
Through holes are evenly distributed both the rotary and the fixed disk

浆流沿着转盘和定盘上的通孔
the pulp flows along the through holes on rotary and the fixed disk

交替迂回运动
alternately circuitous movement

在这个过程中
in this process

浆料受到机械和水力的作用
the pulp is subjected by the mechanical and hydraulic force

使浆料得到疏解
so that the slurry is defibered

由于效率低
Due to its low efficiency

现在使用较少
the application now is much less

圆锥形高频疏解机
Conical high-frequency deflaker

又被称为锥齿式高频疏解机
is also known as cone-tooth type high-frequency deflaker

它的转盘和定盘齿槽通道
The included angle between the channel of the rotary table

与轴中心的夹角为140°
and the fixed plate and the shaft center is 140 °

转子可以沿轴向移动
The rotor can move along the axis

调节齿间间隙
The clearance between the teeth can be adjusted

浆流疏解效果好
The effect of the pulp defibering is good

动力消耗较少
The power consumption is less

齿盘转速为3000r/min左右
The speed of the gear disk is about 3000r/min

产量20～400t/d
The output is 20~400t/d

目前应用较广泛
At present, it is widely used

以上是关于打浆及疏解设备的全部内容
The above is all about pulping and deflaker equipment

在讲解完所有内容后
let’s review the history of the development

我们回顾一下整个打浆设备
