同学们好
Hello everyone

本节我们来学习
In this section we are going to learn

废纸制浆中所用到的碎浆机
the pulping machine used in waste paper pulping

主要介绍碎浆的概要情况
It mainly introduces the brief information of pulping

碎浆机分类
the classification of pulping machine

典型的碎浆设备
the typical pulping equipment

碎浆附属设备、碎浆系统
the auxiliary equipment of pulping, the pulping system

以及疏解机
and the deflaker

首先，我们先看一下碎浆的目的
First, let's take a look at the purpose

作用、重要性和过程
function, importance and process of pulping

碎浆是将废纸变成纤维的过程
Pulping is the process of turning waste paper into fiber

所以它的目的就是将废纸
so its purpose is to disperse

分散成单根的纤维
waste paper into single fiber

碎浆的作用
The function of pulping is to

是在分散纤维的同时
separate the contaminants from the fibers

使杂质与纤维分离
while dispersing the fibers

使废纸与水和化学品等混合均匀
to mix the waste paper with water and chemicals evenly

同时保持杂质尽可能处于较大的尺寸
and to keep the contaminants as large as possible

并避免损伤纤维
and to avoid damaging the fibers

另外，碎浆还要尽可能的
In addition, the pulping should remove the contaminants

去除能够去除的杂质
that can be removed as much as possible

这就是碎浆的作用
That's what pulping does

碎浆是废纸处理里面第一个环节
Pulping is the first link in the waste paper processing

所以它也是非常关键的单元
also the key unit to guarantee

是后续单元效率得以保证的前提
the efficiency of the follow-up units

同时对于后续单元的影响
and meanwhile, it has irreversible influence

具有不可逆性
on the follow-up unit

碎浆的过程包括
The process of pulping includes

遇水后的润湿
wetting after contacting with water

碎浆的循环进行
circulation of pulping

以及纤维之间的摩擦等
and friction between fibers

碎浆机的分类按照运行方式
The classification of pulper can be divided into

可以分为间歇式和连续式
batch type and continuous type according to the operation mode

加料和出浆按照一个完整的周期进行
The feeding and discharging are carried out in a complete cycle

一个周期完成后再开始下一个周期
and the next cycle is followed by the completion of one cycle

这叫做间歇式
This is called batch

如果加料和出浆同时进行
if the feeding and discharging are carried out simultaneously

这就是连续式
this is continuous

另外，按照碎浆时的浓度
In addition, according to the consistency of the pulp

碎浆又可以分为低浓碎浆和高浓碎浆
the pulp can be divided into low and high consistency pulp

与之对应的就是低浓碎浆机和高浓碎浆机
corresponding to the low and high consistency pulper

按照实际生产来看
According to the actual production

旧瓦楞箱板纸OCC这样的非脱墨浆
non-deinking pulp like the old corrugated container OCC

一般用的是低浓碎浆机
generally uses low consistency pulper

而旧新闻纸和办公废纸这类脱墨浆
and old newsprint (ONP) and mixed office waste paper (MOW)

一般用的是高浓碎浆机which are deinking pulp, use high consistency pulper

我们依次来看一下典型的设备
Let's look at the typical equipment in turn

这是低浓碎浆机
This is a low consistency pulper

基本结构包括槽体和转子
the basic structure includes a cell body and a rotor,

其中，槽体上面设置了挡板或者挡浆块
a baffle or a pulp block is arranged on top of the cell body

转子的重心较低
the rotor has a lower center of gravity

靠近槽体底部
near the bottom of the cell

它的工作原理是
Its working principle is that

转子快速转动
the rotor rotates rapidly

将机械能转递给流体
the mechanical energy is transferred to the fluid

产生流体作用力
to produce the fluid force

流体作用力再带动废纸转动
the fluid force then drives the waste paper to rotate

在剪切作用下分散为纤维
the paper will be dispersed into fibers under the shearing action

该类型设备的特点是
The characteristics of this type of equipment are as follows

碎浆浓度较低，为3—6%
low pulp consistency, 3-6%

转子轮廓线低
low rotor profile

旋转速度高
high rotation speed

转子转动产生浆料的涡旋运动
vortex motion of slurry produced by rotor rotation

槽体上的挡板或者挡浆块
the baffles or blocks on the cell

能够破坏浆料的涡旋运动
can destroy the vortex motion of pulp

促进浆料的混合
and promote the mixing of pulp

碎浆过程的机械作用力较强
the mechanical force of pulping is strong

纤维可能受到损伤
the fiber may be damaged

杂质也有可能被碎化
and the impurity may be broken too

这是低浓碎浆机的转子
This is the rotor of the low consistency pulper

左图是标准型伏克斯转子
The left image is the standard Vokes rotor

右图是节能型的
The right image is energy-saving rotor

叶片弯曲
The blade is bent

比标准型节能20%-30%
saving 20%-30% energy comparing with the standard one

这是设置在低浓转子下面的抽提孔板
This is the extraction orifice plate arranged under the low consistency rotor

有大孔抽提孔板和小孔抽提孔板
There are large hole extraction orifice plate and small hole extraction orifice plate

这类设备通常都是连续式的
This type of equipment is usually continuous

也就是低浓连续碎浆机
that is, low consistency continuous pulper

下面来看一下中浓和高浓碎浆机
Now let’s look at the medium and high consistency pulping machine

如果在刚才提及的伏克斯转子上面
If a spiral band is arranged

设置螺旋带
on the Vokes rotor just mentioned

则可以构成中浓转子，如图所示
it can form a medium consistency rotor, as shown in the figure

如果螺旋带增加为3条
If the spiral band is increased to 3

并且设置中心轴为锥形
and the center axis is tapered

则成为高浓转子
it becomes a high consistency rotor

碎浆的浓度可以达到18%左右
and the pulp consistency can reach about 18%

工作状态下
In the working state

浆料顺着螺旋带输送到底部
the pulp is transported to the bottom along the spiral band

在此过程中促使纤维和纤维之间
which causes friction between the fibers

产生摩擦来分散纤维
in the process to disperse the fiber

对于杂质的影响比较小
and has less influence on the contaminants

这种就是典型的高浓碎浆机
This is a typical high consistency pulper

基本结构包括槽体和高浓转子
The basic structure includes a cell body and a high consistency rotor

同样的，槽体也需要设置
Similarly, the cell body also needs to

挡板或者挡浆块
be equipped with abaffles or pulp blocks

它的工作原理主要是靠
Its working principle mainly depends on

转子带动浆料运动
the rotor to drive the pulp movement

纤维与纤维间的摩擦作用分散纤维同时
the friction between the fibers disperses the fiber

将杂质从纤维表面剥离下来
at the same time strips the impurity from the fiber surface

该类型设备的特点是
This type of equipment is characterized

碎浆浓度高，为18-20%左右
by high pulp consistency, about 18-20%

转子轮廓较高，低速旋转
high rotor profile, low rotation speed

纤维和杂质受到的作用较为温和
and gentle effects on fibers and contaminants

这种设备一般属于高浓间歇式碎浆机
This kind of equipment usually belongs to high consistency pulper

下面介绍第三种典型设备
Now let’s come to the third typical equipment

高浓水平鼓式碎浆机
high consistency horizontal drum pulper

通常又称为转鼓碎浆机
is also termed rotary drum pulper

这类设备是连续、高浓碎浆方式
This type of equipment is continuous, high consistency pulping

多用于新闻纸和办公纸的碎浆
mostly used for newsprint and office paper pulping

一般是按照从进料口到出浆口
It is generally installed in accordance with the way

往下倾斜1°的方式安装
downward sloping 1° from the feed port to the discharge port

并且以11-17rpm的速度旋转
and rotates at the speed of 11-17 rpm

该设备通常较为庞大
The equipment is usually relatively large

一般有10英尺高，100英尺长
10 feet high, 100 feet long

从图中可以看出
we can tell from the picture

属于大型设备
it belongs to the large scale equipment

该类设备的优点在于
The advantage of this kind of equipment is that

碎浆方式温和
the pulping method is gentle

能够保持较大的杂质尺寸
it can maintain large impurity size

降低对纤维的损伤
reduce the damage to the fiber

并且操作简单
and operate easily

不足在于，该设备比较昂贵
The disadvantage is that the equipment is more expensive

投入成本较高
the input cost is higher

并且碎浆能力温和
and the gentle pulping is limited

对于难分散开的废纸作用力是有限的
for the hard-to-disperse waste paper

以上是碎浆的三种典型的设备
Above are the three typical equipments for pulping

碎浆仅有碎浆机还不够
It is not enough to only have a pulper

还需要有配套的一些装置
but also need to have a complete set of supporting equipment

先看一下绞绳装置
First look at the deragger

这是专门配用在低浓连续碎浆机上面的
which is specially used on the low consistency continuous pulper

去除杂质的设备
to remove contaminants

可以有效的将铁丝、塑料袋
It can effectively remove contaminants such as

布条等杂质从浆中去除
iron wire, plastic bags, cloth strips from the pulp

除了绞绳装置
in addition to the ragger

还有去杂质机
there is also a contaminants removal machine

与低浓连续碎浆机配合使用
which supporting the low consistency continuous pulper

这张图也是实际生产中非常常见的
This picture is also very common in actual production

用于OCC的碎浆机及配套设施
for OCC pulper and supporting facilities

由于绞绳装置要放绳子到碎浆机里面
The supporting rotors are usually the lifting type

因此配用的转子通常为可升起式
called R rotors

称为R转子
because the ragger needs to put the rope into the pulper

这样就能有效地避免绞绳
In this way, the winding between the rope

与转子之间发生缠绕
and the rotor can be effectively avoided

这里的碎浆机的槽体用的是D型槽
The cell of the pulper here uses a D-shaped cell

与槽体内设置挡板是同一个作用
whose function is the same as the baffle set in the cell body

这就是实际生产中的绞绳装置
This is the ragger in actual production

可以将很多杂质有效的带离浆料系统
which can effectively remove a lot of contaminants from the pulp system

这也是绞绳装置带出来的浆料中的杂质
This is also the impurity in the pulp brought out by the stranding device

这是与废料塔配用的抓斗
This is a grab for the waste tower

以上是低浓碎浆机配用的
Above is the device supporting low consistency pulper

除杂质装置
for removing contaminants

另外，还有与各种碎浆机
In addition, there are also impurity removal machines

都可以配合使用的除杂质机
which can be used in conjunction with a variety of pulper

有各种形式
there are various forms

例如图中所示的圆筒筛
such as the cylindrical screen shown in the picture

能够继续将碎浆排出来的
It is essentially a screening machine

浆渣中的纤维进行回收
that can continue to recycle the fibers

实质上它就是个筛分机
in the foam out of the pulp

通常，与各种碎浆机都可以配合使用
Usually, it can be used in conjunction with various pulping machines

如图所示，低浓连续碎浆机
As shown in the picture, the pulp foam

排出的浆渣采用除杂质机
discharged by the low consistency continuous pulper

进行了两次的纤维回收处理
is recycled twice by the contaminants remover

这里碎浆机和除杂质机
where the pulper and the contaminants remover

组成了一个较为完整的碎浆系统
form a more complete pulping system

如图所示，这是高浓间歇碎浆机
As shown, this is a pulping system consisting of

与除杂质机组成的碎浆系统
a high consistency batch pulper and an impurity remover

去除杂质的同时
While removing contaminants

回收浆渣中的纤维
the fiber in the pulp foam is recovered

这是添加了稀释水后
This is a pulping system consisting of

构建的高浓连续碎浆机
high consistency continuous pulper

和除杂质机构成的碎浆系统
and an contaminants removal mechanism after diluted water is added

以上是有关碎浆机、除杂质机
The above is the introduction of the pulper

和碎浆系统的介绍
the impurity remover and the pulping system

实际生产中
In actual production

仅有碎浆系统还不够
only the pulp system is not enough

可能还存在分散不开的废纸
there may be waste paper which can’t be dispersed

比如湿强度较高的废纸
such as waste paper with high wet strength

因此还需要设置机械设备进行处理
Therefore, the mechanical equipment

就是疏解机
deflaker is needed

它的作用其实是辅助碎浆
Its function is to assist the pulping

可以有效的降低碎浆产生的能耗
which can effectively reduce the energy consumption of pulping

针对性的分散强度较高的废纸原料
targeted dispersion of high-strength waste paper raw materials

常见的疏解机有两种
There are two kinds of common deflaker

一种是纤维分离机
one is defibering machine

主要用于低浓连续碎浆之后
which is mainly used after low consistency continuous pulping

另一种是高频疏解机
the other is high frequency deflaker

主要用于添加了增强剂的
which is mainly used for auxiliary pulping

废纸的辅助碎浆
of waste paper with reinforcing agent

以上就是有关碎浆机的内容
That's all about the pulper
