  • the pulper has six major drawbacks:
  • the pulping time is longer, 30 ⁇ 40 minutes; the reason is that the disintegration of the waste paper is mainly achieved by the shearing and friction between the spiral rotor and the waste paper. Because the diameter of the spiral rotor is relatively small, it is only the pulper tank. The shearing and friction frequency between the spiral rotor and the waste paper is low at 1/5 of the body diameter.

一种反刍式高浓碎浆机
技术领域
本发明涉及造纸工业中的废纸碎浆机。 背景技术
我国的制浆系统， 超过 2/3 是废纸制浆， 废纸制浆在我国造纸工业中占有十分重 要的地位。 废纸制浆的第一个设备是碎浆机， 碎浆机的碎浆效果决定废纸纸浆的质量 和得率， 碎浆机配备的电机在废纸制浆系统中是最大的， 碎浆机碎浆效果和动力消耗 都与碎浆机的碎浆方式有关， 碎浆机的碎浆方式是否科学合理， 显得十分重要。
现代废纸制浆工艺要求废纸碎浆时间越短越好， 造纸专家实验证明： 废纸碎浆的 时间最好不超过 15秒； 如果碎浆时间过长， 将会造成油墨粒子重新沉积在纤维上， 形 成不可逆的油墨残留， 对废纸脱墨效果造成不可挽回的影响。 碎浆时间长短不仅决定 废纸碎浆脱墨效果， 也决定了碎桨机的效率和动力消耗； 实验室内小型碎浆机能够在 15秒之内将废纸碎成纸浆， 而实际生产中的大型碎浆机目前还不能， 这一难题亟待解 决。
碎浆机的碎浆方式决定了碎浆时间， 碎浆方式是碎浆技术的关键； 废纸中最难碎 浆的是书本。 目前我国的高浓碎桨机主要有立式高浓水力碎浆机和转鼓式高浓碎浆机 两种。 下面分别以 5m3立式高浓水力碎浆机和 150t/d转鼓式高浓碎浆机为例来说明其 碎浆方式及各自的缺陷。
5m3立式高浓水力碎浆机的碎浆方式是靠螺旋转子把废纸撕碎， 并通过螺旋转子 将碎纸自上而下传送到碎浆机的底部， 由底部推向四周， 再由四周自下而上将碎纸推 举到一定高度， 碎纸再从四周向碎浆机中心一螺旋转子汇聚； 碎浆机内的碎纸整体做 上下往复运动， 直至废纸完全碎解。 该碎浆机有 6大缺点：
1.动力消耗高， 40 k w h / t ；原因是在螺旋转子将碎纸推举到一定高度的过程中， 要克服 5吨的重力作功。 '
2. 碎浆时间较长， 30~40 分钟； 原因是废纸的碎解主要通过螺旋转子与废纸之 间的剪切和摩擦作用来实现， 由于螺旋转子直径比较小， 只是碎浆机罐体直径的 1/5， 故螺旋转子与废纸之间的剪切和摩擦频率低。
3. 碎浆浓度低， 10— 14 %； 原因是浓度高于 14 %时碎浆机内的纸浆就不能上 下翻动， 碎浆效果会受到很大影响。
4. 效率低， 12t/d ； 原因是该机属于间歇式碎浆， 且每罐碎浆时间较长。
5. 书本碎浆温度高， 9(TC ; 原因是温度低于 90°C时该机不能使书本很好地碎解和 脱墨
6. 书本中胶块不能有效分离； 原因是书本碎浆温度高时会使书本中胶块熔化， 变 成非常小的胶团， 很难从纸浆中分离， 使纸机抄纸出现障碍。
150t/d转鼓式高浓碎浆机是近几年来我国一些造纸设备厂根据国外同类产品改良 设计而成的一种大型高效碎浆设备， 其维形是芬兰一位机械工程师参考滚筒式洗衣机 的工作原理研制出来的；碎浆方式是废纸在十多米长略带倾斜的圆筒里缓慢向前移动， 圆筒内壁兜板不断将废纸兜到一定高度时借重力将其摔落到筒底， 经过多次摔打， 靠 剪切力将废纸碎解。 该碎浆机有 6大缺点：
1. 动力消耗较高， 20 k w h / t ； 由于该机总长 16300mm， 圆筒直径 2750mm， 占 地面积较大， 体大笨重。
2. 碎浆时间长， 30分钟； 由于废纸行走路程长， 转筒转数慢。
3. 废纸碎解的效果不理想， 需要疏解机的帮助； 原因是碎解方式温和， 废纸之间 摩擦和剪切作用小。
4. 碎桨浓度不高， 14~18% ； 碎浆浓度高于 18%时， 纸浆流动性差， 影响纸浆 前进速度， 延长碎浆时间。
5. 书本碎浆温度高， 90°C ; 原因是温度低于 90°C时该机不能使书本很好地碎解和 脱墨
6. 书本中胶块不能有效分离； 原因是书本碎浆温度高 时会使书本中胶块熔化， 变成非常小的胶团， 很难从纸浆中分离， 使纸机抄纸出现障碍。 发明内容
本发明提供一种反刍式高浓碎浆机， 目的是解决碎浆机的碎浆时间、 碎浆浓度、 碎浆温度、 能源和水消耗等技术问题， 使其达到碎浆速度快、 降低能源和水的消耗， 提高碎浆浓度， 降低碎浆温度， 能通过小型吹风机把纸桨里的塑料等轻杂质分离， 书 本上的胶块不会被碎成小块， 而是以较大的胶块从纸浆中游离出来， 并能连续碎浆， 占地面积小。
本发明是通过以下技术方案实施的： 一种反刍式高浓碎浆机， 包括罐体， 设置在罐体内的传动轴， 罐体一端上部有入 料口、 注水口， 另一端下部有出料口， 其特征在于： 罐体的外形为紡锤形， 两端直径 小， 中部直径最大； 罐体前半段的传动轴上有废纸推进片和锯齿状的推进螺旋， 锯齿 状的推进螺旋沿传动轴呈螺旋线展开； 罐体后半段的传动轴上有块状的疏解片， 块状 的疏解片分为两种， 一种是使物料向出料口方向推进的， 为正疏解片； 另一种是使物 料向入料口方向回流的， 为反疏解片。
罐体前半段分为两个区， 靠近入料口一端为破碎区， 靠近罐体中部的为搅泮区， 搅拌区的锯齿状推进螺旋的齿间距离要比破碎区的锯齿状推进螺旋齿间距离大， 搅拌 区的锯齿状推进螺旋的齿深度也比破碎区的锯齿状推进螺旋的齿深度深； 破碎区的长 度小于搅拌区的长度。
罐体后半段传动轴上的正疏解片和反疏解片均设置在传动轴的螺旋线上， 其中正 疏解片设置在正螺旋线上， 反疏解片设置在反螺旋线上。
罐体后半段传动轴上的正疏解片和反疏解片沿传动轴的多条螺旋线展开， 且各螺 旋线在传动轴的横截面上均匀分布。
正螺旋线与反螺旋线的交点为块状的疏解片与传动轴连接部分的中心， 正疏解片 与反疏解片在螺旋线的交点处交替排列。
另外一个方面， 本发明提供一种碎浆机， 其包括罐体， 在罐体内设有传动轴， 其 中， 沿着从入料口到出料口的方向， 传动轴上设有废纸推进片、 推进螺旋以及疏解片， 其中， 罐体中部的直径大于罐体两端部直径， 从而物料向入料口方向回流。
罐体中部位于沿罐体的长度方向的 1/8处至 1/2处之间的位置。
其中， 所述疏解片包括正疏解片和反疏解片， 所述正疏解片使物料向出料口 （6) 方向推进， 所述反疏解片使物料向入料口 （1 ) 方向回流。
其中， 正疏解片的宽度大于反疏解片的宽度。

(2) 碎浆时间短， 15秒以内， 满足废纸脱墨工艺要求；
(3 ) 碎浆浓度高， 30— 35 % ；

( 7) 占地面积小， 占地面积是相同产量的转鼓式高浓碎浆机的九分之一
( 8 ) 设备耗材少， 耗材是相同产量的转鼓式高浓碎浆机的十分之一 。 附图说明

图 3为本发明的反刍式高浓碎浆机的剖面图。 具体实施方式
下面结合附图对本发明进行具体说明：
图 1为本发明的反刍式高浓碎浆机的侧视图， 图 2为本发明的反刍式高浓碎浆机 的正视图， 图 3为本发明的反刍式高浓碎浆机的剖面图， 其中 1为入料口， 2为破碎 区， 3为注水口， 4为搅泮区， 5为废纸推进片， 6为出料口， 7为风机， 8为轻杂质 出口， 9为罐体， 10为传动轴， 11为块状的疏解片， 12为鋸齿状推进螺旋。
牛反刍是将胃里的食物草回流到口腔内， 反复咀嚼， 将草磨得更碎， 再咽到肚里， 反刍起辅助消化作用。 本发明根据牛反刍原理， 设计出纸浆回流装置， 来增加纸的剪 切、 摩擦和揉搓几率， 达到快速碎浆之目的， 具体技术方案如下：
罐体 9的外形为纺锤形， 两端直径小， 中间直径最大； 这样设计的目的在于使废 纸进入罐体后， 能够将废纸快速推进到破碎区 2和搅拌区 4， 而到罐体 9的后半段， 罐体 9直径逐渐变小， 会减缓废纸前进速度， 使废纸的疏解时间延长， 以此来保证碎 浆效果。这里所述的中间处， 可以位于罐体的 1/2处附近， 也可以位于罐体的 1/3处附 近或者 1/4处附近。
传动轴 10的前半段有废纸推进片 5和锯齿状推进螺旋 12， 锯齿状推进螺旋 12沿 传动轴 10呈螺旋线展开。 而根据鋸齿状推进螺旋 12齿间距和齿深度的不同， 罐体 9 的前半部又分为两个区，靠近入料口 1一端为破碎区 2，靠近罐体 9中部的为搅拌区 4， 搅拌区 4的锯齿状推进螺旋 12的齿间距离要比破碎区 2的锯齿状推进螺旋齿 12间距 离大， 搅拌区 4的锯齿状推进螺旋 12的齿深度也比破碎区 2的锯齿状推进螺旋 12的 齿深度深； 破碎区 2的长度小于搅拌区 4的长度。
计重传送带将废纸输送到入料口 1， 此处传动轴 10上的废纸推进片 5使废纸很快 进入破碎区 2， 破碎区 2的锯齿状推进螺旋 12瞬间将废纸破碎成纸片， 并推动破碎纸 片进入搅拌区 4， 搅拌区 4内的碎纸片立即与脱墨剂水溶液或水混合； 搅拌区 4的锯 齿状推进螺旋 12的齿间距离要比破碎区 2的大， 齿的深度也比破碎区 2的深， 以此来 加大搅拌力度， 使纸片与脱墨剂水溶液或水充分接触， 达到纤维完全吸水润透， 为纤 维的有效疏解创造条件；润透的纸片在锯齿状的推进螺旋 12的推动下进入罐体 9的后 半部。
罐体 9后半部的直径逐渐变小， 且罐体 9后半部的传动轴 10上有块状的疏解片 11 . 块状的疏解片 11分为两种， 一种是使物料向出料口 6方向推进的， 为正疏解片； 另一种是使物料向入料口 1方向回流的， 为反疏解片， 正疏解片和反疏解片均设置在 传动轴 10上， 沿传动轴 10的多条螺旋线展开， 且各螺旋线在传动轴 10的横截面上均 匀分布， 其中正疏解片设置在正螺旋线上， 反疏解片设置在反螺旋线上。 正螺旋线与 反螺旋线的交点为块状的疏解片 11与传动轴 10连接部分的中心， 正疏解片与反疏解 片在螺旋线的交点处交替排列， 其含义为： 当正螺旋线与反螺旋线相交时， 其交点必 须在一个块状的疏解片 11与传动轴 10相交部分的中心， 在这些交点上， 正疏解片与 反疏解片都是交替排列的， 即当某一个交点上的块状的疏解片 11为正疏解片时， 下一 个交点上的块状的疏解片 11必须为反疏解片， 再下一个交点上的块状的疏解片 11则 为正疏解片， 以此类推。
这里的 "反刍"功能通过两个措施来实现， 一个是逐步缩小的罐体 9直径， 罐体 9 直径一收缩就会使纸浆回流， 罐体 9直径收缩得越大， 纸浆回流得越多； 正疏解片推 进纸浆， 反疏解片回流纸浆， "反刍 "功能主要靠反疏解片回流纸浆来实现； 反疏解片 强制回流纸浆， 与此同时相邻的正疏解片向前推进纸浆； 这样纸浆有的被推进， 有的 被回流， 就会使纸浆之间产生强烈揉搓摩擦作用， 这样才能达到满意的疏解效果和有 效地保护纤维； 使纸浆的品质达到新的高度。
以书本原料为例，根据本发明所述技术方案可以带来如下的具体技术和经济指标: 碎浆时间 < 15秒
碎浆浓度 30— 35 %
碎桨温度 > 15°C
动力消耗 8— 1 0 k w h / t
