Description

一种改进的洗浆机或分丝机 技术领域
本方案涉及造纸机械技术领域，更具体地说，是涉及一种结构简单、具有洗浆或分丝功能的机器。
 背景技术
分丝机是造纸机械较为常用的设备，用于破坏浆料中纤维束的内部结合力，现有技术中的分丝机结构如图1所示，用两个螺旋进行相对挤压，左侧的螺旋挤压力大于右侧的螺旋挤压力，最终将浆料从右侧的出料口挤出，这种结构的分丝机操作条件苛刻，对浆料的填充率要求较高，当填充率低时，没有分丝效果，当填充率高时，又会破坏纤维的长度，而且动力消耗高，大部分的电能会通过纤维的相互挤压摩擦转换为低效的热能，造成能源的浪费。
洗浆机也是造纸机械较为常用的设备，用于实现纸浆的脱水，现有技术中的洗浆机结构如图2所示，喷浆箱1将纸浆喷入沟纹辊2与脱水网3之间，利用沟纹辊的离心力脱水，然后再利用脱水网3与回头辊4之间的挤压力进行挤压脱水，这种结构的缺点是出浆浓度低，一般很难超过15%。
 技术问题
本方案的目的在于提供一种改进的洗浆机或分丝机，以解决现有技术中分丝机或洗浆机存在缺陷的技术问题。
 技术解决方案

设于回头辊与压榨中心辊之间且用于向承托网上布料的布料器；以及
与压榨中心辊相抵的至少一个压榨子辊，所有的压榨子辊均与承托网接触。
进一步地，还包括实现承托网振动的摇振装置，用于将布料器布在承托网上的原料均匀再分布。

进一步地，承托网的张力大于或等于30kgf/cm。
 有益效果
改进的洗浆机或分丝机可以利用承托网对压榨中心辊的外表面所形成的弯曲张力实现压榨脱水，同时会对附着在压榨中心辊上的浆料进行定型作用，防止压榨子辊压溃浆层，大大提高出浆浓度，出浆浓度可以达到浆料的极限脱水浓度48%以上，甚至可以破坏浆料中纤维束的内部结合力，实现分丝功能。

当至少一个压榨子辊10与压榨中心辊7之间的线压力达到3000kgf/cm时，可以对造纸原料或者对半生料进行直接分丝，具有良好的分丝效果，如果处理的原料为木片时，只需经过3-5次挤压分丝，即可达到良好的分丝效果。
其次，当处理对象是木浆时，承托网8的张力大于或等于15kgf/cm条件下，即可实现对浆料的极限机械脱水。
当处理对象是脱墨浆时，承托网8的张力大于或等于30kgf/cm条件下，即可实现对浆料的极限机械脱水。
另外，该实施例还包括实现承托网8振动的摇振装置（图中未示出），用于将布料器9布在承托网8上的原料均匀再分布。此处的摇振装置可直接安装在回头辊4上，通过回头辊4的震动带动承托网8振动。
本方案改进的洗浆机或分丝机结构简单、使用方便，能够实现洗浆功能或分丝功能，具有很好的实用性。
以上所述仅为本方案的较佳实施例而已，并不用以限制本方案，凡在本方案的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本方案的保护范围之内。
