Description

废纸破碎部件及装置 技术领域
本实用新型涉及废物回收与处理领域，具体涉及一种废纸破碎部件及装置。
背景技术
在废物的回收利用中，需要采取有效措施去除废物中的诸如粉灰、颗粒等杂质。以废纸回收为例，回收的废纸包括办公废纸、废旧包装箱、废旧水泥袋等。为了实现废纸的再利用，需要将废纸中的杂质尽量去除干净，使得后续得到的纸浆的灰分含量接近原纸的灰分含量(5％以下)。
目前的废纸处理系统包括输送机(例如，皮带机或链板机)、散包机、和D型水力碎浆机。在废纸处理过程中，废纸首先经输送机进入散包除尘机，成捆的废纸随散包机内的滚筒翻转，并与滚筒内壁上的顶柱等撞击后散开，部分杂质在滚筒的离心力的作用下通过筛孔排出。散开的废纸经滚筒内的螺旋板输出，并通过输送机送至D型水力碎浆机。D型水力碎浆机对废纸进行碎解并将不易碎解的杂质排出，并进入后续的筛选净化系统。
在上述的废纸处理系统中，散包机只能去除废纸表面和废纸间夹带的杂质，对于包裹在废纸袋角中的杂质很难去除。如果废纸袋在这种情况下直接被碎浆，废纸碎片中具有较强吸附作用的羟基与细小的杂质颗粒相互吸附，在后续的筛选净化系统中将更加难以去除。
因此，需要在上述的废纸处理系统中增加废纸破碎装置，并且要求废纸破碎装置能够有效的对废纸袋进行破碎处理，使废纸袋角中的杂质暴露出来。

根据一个示例性的实施例，齿部为锯齿形结构。
利用本实用新型提供的废纸破碎部件，可以将大块的废纸破解成废纸碎片。并且在废纸的破碎过程中，通过齿部首先在废纸上切出开口，第一刃部和第二刃部的其他配合部分可沿此开口进一步将废纸切开，从而达到有效破碎废纸的目的，使包裹在废纸中的杂质暴露出来。

喂料组件70还可以包括多个喂料辊并且沿废纸进入废纸破碎部件100的方向排布，喂料辊距离入料通道60的高度沿废纸进入废纸破碎部件100的方向逐渐降低。如此设置后，在喂料过程中，多个喂料辊可以依次将堆叠的废纸压紧压实，并通过喂料辊的旋转运动(沿图5中的S’方向转动)将堆叠的废纸逐渐撵薄并均匀送入废纸破碎部件100的第一刃部121和第二刃部221之间。
在一些实施例中，为了提高废纸破碎部件100的工作效率，可以设置多个喂料辊的转速沿废纸进入废纸破碎部件100的方向逐渐增加，使得废纸破碎部件100能够连续不断的切断废纸。
在一些实施例中，喂料辊与入料通道60之间的距离还可以根据废纸堆积的高度进行调整，以满足应用在不同应用环境中的使用需求。
