旋转时有效地把木片打入水中
which effectively drives the chips into the water while rotating
两根螺旋叶片则把木片向前推进
and the two screw blades push the wood chips forward
右图是锥型转子木片洗涤机
The figure on the right is a conical rotor wood chip washer
木片沿洗涤机的壳壁进入洗涤机内
The chips enter the washer along the shell wall of the washer
由于循环水切向进入洗涤机壳体
Due to the tangential movement of the circulating water into the washer shell
以及锥形转子的旋转运动
and the rotation of the conical rotor
使木片迅速地随水流涡旋运动
the chips quickly move to the bottom of the conical shell
而走向锥形壳的底部
with the vortex motion of the water flow
然后从中心升起
and then rise from the center
在离心力激烈湍流的作用下
to separate the sundries under the action
使杂物从木片中分离出来
of the intense turbulence of the centrifugal force
洗涤后的木片经中心管
After washing, the chips flow out with water through the central pipe
随水溢流出而进入脱水筛脱水
and enter the dehydration screen for dehydration

木片从加料口加入
The chips are added from the feeding port
经螺旋挤压后
after screw extrusion
木片中的空气被挤出后
the air in the wood chip is extruded
木片变得紧实
and the chips become tight
这样木片在离开螺旋进料器
In this way, the chips will expand freely
进入木片浸渍提升螺旋时
without restraint as they leave the screw feeder
就无约束地自由膨胀
and enter the chip impregnation lifting screw
随着螺旋转动向上提升的过程中
As the screw rotates upward
木片均匀地吸收加进去的化学药液
the wood chips absorb the added chemical liquor evenly
然后从浸渍提升螺旋的顶部落入
and then fall from the top of the impregnation lifting screw
预热器的蒸汽加热腔中
to the steam heating cavity of the preheater
这些经过加热和化学药物
Because the chips are treated by heating and chemicals
综合处理的木片进入磨浆机的磨区
their fibers are easy to be separated
就更容易把纤维给分离出来
when they enter the grinding area of the refiner
而对纤维的损伤可减到最低程度
and the damage to the fibers can be minimized
提高了浆料质量
