再进行筛选、脱水
and then subject to screening and dehydration

相信大家都还记得制浆课里

所学的消潜的作用
we learned in the pulping class

主要就是使得在磨浆过程中
which is mainly to make crimped fibers

卷曲的纤维在热水中舒展开

盘式磨浆机主要由
The disc refiner is mainly composed of

装在磨片的磨盘
a refiner disc installed on the refining plate

主传动轴、外壳
a main drive shaft, a shell

间隙调节机构
a gap adjusting mechanism

轴承冷却系统和保护系统
a bearing cooling system and a protective system

以及进出浆口和电机等构成
as well as an inlet and outlet port and an electric motor

物料从盘中心进入
The material enters from the center of the disc

在高速转盘巨大的离心力的作用下
moves from the center of the disc to the circumference

从磨盘中心向圆周方向运动
under the action of the huge centrifugal force of the high-speed rotary disc

穿过盘齿间隙最后流向出口
and flows through the clearance of the disc teeth to the outlet

目前常用的盘式磨浆机可分为
At present, the disc refiner can be classified into three types

单盘磨、双盘磨和三盘磨三种
single disc refiner, double disc refiner and three-disc refiner

单盘磨又可分为The single disc refiner can be classified into

悬臂式结构和通轴式结构
cantilever structure and through shaft structure

上图是悬臂式结构的单盘磨
The above figure is the single disc refiner of the cantilever structure

磨盘安装在主轴的末端
and the disc is installed at the end of the spindle

下图是通轴式结构的单盘磨
The following figure is the single disc refiner of through shaft structure

通轴式的盘磨机旋转的磨盘
The rotating disc of the through shaft refiner

安装在主轴的中部
is installed in the middle of the spindle

两端由轴承支撑
and the two ends are supported by bearings

单盘磨由1个定盘和1个动盘组成
Single disc refiner is composed of 1 fixed disc and 1 moving disc

由1台电动机带动转轴上的动盘
and one motor drives the moving disc

旋转进行磨浆
on the shaft to rotate for refining

浆料由定盘中心孔进入磨浆机
The pulp enters the refiner from the center hole of the fixed plate

动盘转速大约1500～1800r/min
The rotating speed of the moving disc is about 1,500-1,800r/min

磨盘间隙通过液压系统
The gap between the discs can be adjusted

或齿轮电动机进行调节
by the hydraulic system or the gear motor

一个磨盘旋转，另一磨盘固定不动
One disc rotates while the other is fixed

木片利用环绕主轴上的
The wood chips are fed into the refiner

螺旋带喂入磨浆机
by adoption of a spiral belt surrounding the spindle

喂料螺旋可以单独传动
The feeding screw can be driven separately

也可以随主轴转动
or rotate with the spindle

图中所示的是安德里茨公司的
The figure shows here is the SB150/170

单盘磨SB150/170
single disc refiner of Andritz Company

This is a photo of the work site of the disc refiner

这是安德里茨公司
This is the technical specification

和顺智公司的
for the single disc refiner of Andritz Company

单盘磨的技术规格
and Sunds Defibrator Company

从这两个表我们可以看出
From these two tables, we can see that

整体来看
on a whole

单盘磨的电耗是很高的
the power consumption of the single disc refiner is very high

这也印证了之前我们所讲的
which also proves that the energy consumption

能耗在高得率制浆生产成本中
we mentioned earlier occupies an important part

占据重要的组成部分
in the production cost of high-yield pulping

所以整个高得率制浆的装备
so the development of the whole equipment

和工艺的发展
and technology of high-yield pulping

就是围绕着提高纸浆质量
is around the two themes of

和节能两个主题在进行
improving pulp quality and energy saving

我们从表中还可以看出
We can also see from the table that

随着磨盘直径的增大
with the increase of the diameter of the disc

转速增大
the rotating speed increases

能耗也同时的增大
and the energy consumption increases at the same time

磨盘直径1.5米
For single disc refiner with disc diameter of 1.5m

转速1800r/min的单盘磨
and the rotating speed of 1,800r/min

电动机的功率达到了17000千瓦
the motor power reaches 17,000kW

双盘磨由两个
The double disc refiner is composed of

转向相反的动盘组成
two moving discs with opposite rotation direction

各由1台电动机带动
each of which is driven by a motor

转速为2400～3000r/min
with a rotating speed of 2,400~3,000r/min

通过双螺杆进料器强制进料
It is forcibly fed through a double-screw feeder

利用线速传感器
and can accurately control the gap of the disc

可以准确控制磨盘的间隙
by using a linear speed sensor

两个磨盘都装在悬臂上
Both of the discs are mounted on the cantilever

作反方向旋转
and rotated in the opposite direction

木片通过同轴的喂料螺旋
The wood chips are fed from the center port

由一个转盘的中心口喂入
of a turntable through a coaxial feeding screw

也有由一磨盘斜方向喂入的
and some are also fed in the inclined direction of the disc

这是安德里茨公司的
This is the SB160/190

SB160/190双盘磨
double disc refiner of Andritz Company

这是顺智公司的双盘磨
This is the double disc refiner of Sunds Defibrator Company

这是安德里茨公司和顺智公司的
This is the technical specification for the double disc refiners

双盘磨的技术规格
of Andritz Company and Sunds Defibrator Company

由于两台电机分别
Since two motors drive two discs

驱动两个磨盘相反旋转
to rotate in the opposite direction

所以能耗增加了一倍
the energy consumption is doubled

当然，产能也增加了
and of course, the production capacity is increased

三盘磨由2个定盘
The three-disc refiner is composed of two fixed discs

和中间1个动盘组成
and one moving disc in the middle

动盘两侧都有齿面
Both sides of the moving discs have tooth surfaces

分别与2个定盘
that form two refining cavities

组成2个磨浆室
with 2 fixing discs respectively

磨浆面积提高了一倍
and the refining area is doubled

这种结构使得即使转速很高
This structure makes that even if the rotating speed is very high

也不存在动盘偏斜的问题
there is no problem of deflection of the moving disc

磨浆过程中产生的蒸汽
The steam generated during the refining process

可由2个进料口
can be discharged from two feeding ports

和1个出料口排出
and one discharging port

轴向联动的2个定盘
The axial linkage of the two fixed discs

通过液压系统
through the hydraulic system

可以调整间隙
can adjust the gap

和对动盘施加负荷
and apply the load to the moving disc

这种构型的磨浆机
This refiner with such configuration

不需使用大的推力轴承
does not need to use large thrust bearings

由于两边固定的盘磨
Due to the mutual counteraction of the pressure

对中间转盘加压的力
exerted by the fixed discs on both sides

相互抵消
to the middle rotating discs

因此实际上不存在轴推力
there is no axial thrust actually

磨盘也不会变形
and the disc will not deform

在任何操作条件下
so it can maintain good parallelism

都能保持良好的平行度
under any operating conditions

近年来
In recent years

盘磨机在自动化、控制、大型化方面

有了巨大的进步和发展
in the aspects of automation, control and large-scale

同时也随着人们对节能的重视
and at the same time, with people's attention to energy saving

也涌现出一些新型的结构
some novel types of structures have emerged

大家可以看看图中所示的这个结构
We can look at the structure as shown in the figure

看看能否体会出这个结构设计的奥秘
Can you understand the secrets of this structure design

仔细观察我们就能发现
Through careful observation, we can find that

这个盘磨机的结构
the structure of this disc refiner

不同于前面所述的
is different from the above

单盘磨、双盘磨和三盘磨
single disc refiner, double disc refiner and three-disc refiner

它将一个动盘和两个静盘所形成
It connects two refining areas formed by

的两个磨区串联起来磨浆
one moving disc and two static discs for refining

一台机器、一个动盘实现了两段磨浆
One machine and one moving disc realize two-stage refining

达到了节能、高效率的效果
achieving the effect of energy saving and high efficiency

本节就先讲到这里
That’s all for today
