Description

一种改进的新月型夹网纸机成型器 技术领域
本方案涉及造纸机械技术领域，更具体地说，是涉及一种改进的新月型夹网纸机成型器。
 背景技术
目前，夹网纸机成型器是造纸机械中较为常用的设备，一般是指在湿纸页成形过程中采用成型网和毛布，由两面同时脱水的成型器。如图1所示，即为传统的夹网纸机成型器的结构示意图，其通过流浆箱1向成型网2与毛布3之间喷射纸浆，在转速较快的成型辊4的离心力作用下，通过成型网2进行离心脱水，此过程中湿纸页被紧紧夹在成型网2与毛布3之间，在成型网2与毛布3分离后，湿纸页5粘附在毛布3的上表面上输送出来，此时，湿纸页5的干度在15%左右，后续再通过真空吸水箱6进行吸水，使湿纸页的干度达到20%左右，再对湿纸页进行至少一道机械压榨脱水，使湿纸页的干度达到30-45%左右，最后再将湿纸页输送入烘干部进行烘干即可。这种结构存在诸多缺点：
一是必须通过三个相互独立的阶段才能完成湿纸页的物理脱水过程，即离心脱水阶段、真空脱水阶段和机械压榨脱水阶段，不仅设备结构复杂，而且动力消耗大，主要包括真空泵本身的动力消耗和真空吸水箱6面板与毛布3背面的机械摩擦力所浪费的动力；
二是真空吸水箱6将毛布5紧紧吸附住,摩擦力增加,减少了毛布3的使用寿命；
三是离开成型网2后的湿纸页再进入机械压榨部，由于失去了成型网2张力对湿纸页的弯曲定型作用，大大限制了机械压榨线压力的提高，因此对于较厚的纸页，为了防止压出的水将湿纸页冲溃，一次压榨的线压力不宜过大，为此不得不设置多道线压力不断增加的机械压榨部来完成对湿纸页的压榨脱水过程，进一步增加了设备造价和压榨部动力消耗。
除此之外，如图2-图6所示，为现有技术中几种较为常见的机械压榨脱水结构的示意图，这几种结构安装于图1所示的真空吸水箱6后方，实现对湿纸页的机械压榨脱水。
其中，图2所示为反向脱水普通压榨技术，其虽然具有结构简单、造价低的优点，但也存在较大的缺陷：尽管该结构设置了压榨偏心距，但同时减小了有效压榨力，降低了压榨的效果，压出来的水也容易冲垮湿纸页。
图3所示为真空压榨技术，其在下方的压辊上开设若干的开孔，利用真空将压出的水垂直向下吸出，这种结构虽然避免了反向脱水，一定程度上减少了对湿纸页的压溃现象，但是造价较高，动力消耗高，设备结构复杂，而且受开孔率的限制，压榨力也受到了极大的限制。
图4所示为宽压区压榨技术，由于传送带7与压块8之间存在摩擦力，造成结构复杂、动力消耗高、产品造价高的缺点。
图5所示为盲孔压榨技术，其在下方的压辊上开设若干的储水孔，压出的水会暂存在这些储水孔内，最终排放，其虽然也属于垂直脱水的一种，但是没有真空的辅助作用，脱水效果比真空压榨还低，制作也麻烦。另一种与盲孔压榨较为相似的为沟纹压榨技术，其在压辊上不是开孔，而是开设沟槽，压出来的水暂存在沟槽内，但这种结构的水很容易被纸页吸回，出现回湿的问题。
图6所示为衬网压榨技术，其在两个压辊之间、毛布3的下边设置一层衬网9，衬网9上同样开设若干的网孔，压榨出来的水可以暂存在这些网孔内，由于网孔的容积有限，往往满足不了使用要求。
 技术问题
本方案的目的在于提供一种改进的新月型夹网纸机成型器，以解决现有技术中存在的脱水效率低、设备成本高的技术问题。
 技术解决方案
为实现上述目的，本方案采用的技术方案是：提供一种改进的新月型夹网纸机成型器，包括：
旋转的成型辊；
贴附于成型辊的部分外表面上的毛布；
贴附于毛布外表面上的成型网，成型网在成型辊上的包覆角大于或等于60°；
设于毛布与成型网之间且用于向二者之间喷射纸浆的流浆箱；以及
与成型辊相抵的压榨辊，压榨辊与成型辊的相抵点位于毛布与成型网的接触点之后。
进一步地，压榨辊与成型辊的相抵点位于毛布与成型辊分离点之前或与所述分离点重合。
进一步地，毛布与成型辊的分离点之后设有用于将成型网上的湿纸页向毛布上转移的转移装置。
进一步地，转移装置为附着在成型网背面的吹风装置。
进一步地，压榨辊与成型辊之间的线压力大于或等于400kgf/cm。
进一步地，压榨辊与成型辊之间的线压力大于或等于500kgf/cm。

进一步地，成型网的张力大于或等于10kgf/cm。
进一步地，成型网的张力大于或等于15kgf/cm。
 有益效果
改进的新月型夹网纸机成型器利用成型辊与压榨辊之间可以进行机械挤压脱水，直接达到机械脱水48-50%的极限干度，比传统的各种压榨方式的最高干度至少高2个百分点，而且节电50-70%，节约蒸汽消耗8-40%，延长毛布的使用寿命1-2倍，提高纸页的湿强度1-2倍，提高纸页的干强度至少20%，提高纸页的抄造率（减少断头）1-3个百分点，设备的造价降低到原来的1/2到1/5，大大降低制造成本，设备的维修成本降低到原来的1/5以下，设备操作更简单，工人的劳动强度和操作难度更低，由于不使用真空泵等高噪音设备，工人的操作环境大大改善，将成型网在成型辊上的包覆角设置为大于或等于60°可以充分利用成型辊的离心力进行脱水，脱水成本更低。

 本发明的实施方式
为了使本方案所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本方案进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本方案，并不用于限定本方案。
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者间接在该另一个元件上。当一个元件被称为是“连接于”另一个元件，它可以是直接连接到另一个元件或间接连接至该另一个元件上。
需要理解的是，术语“长度”、“宽度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本方案和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本方案的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本方案的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
如图7所示，为本方案改进的新月型夹网纸机成型器的实施例一的结构示意图，图中所示箭头为各个部件的运动方向，波浪线代表湿纸页（后续的实施例相同），该成型器包括旋转的成型辊4，所述成型辊4的部分外表面上贴附有毛布3以及贴附在毛布3外表面上的成型网2，在毛布3与成型网2之间设有向二者之间喷射纸浆的流浆箱1，还包括与所述成型辊4相抵的压榨辊10，所述压榨辊10与成型辊4的相抵点位于毛布3与成型网2的接触点之后，所述成型网2在所述成型辊4上的包覆角（即图中的角度A）大于或等于60°。流浆箱1喷射出来的纸浆进入毛布3与成型网2之间后，首先会通过成型辊4的离心力作用实现脱水，这种脱水成本较低，在成型辊4的一侧设置接水盘（图中未示出），此处的成型辊4可选用真空辊。湿纸页被夹在毛布3与成型网2之间，当到达成型辊4和压榨辊10的接触点时，即进行机械挤压脱水，经实际实验数据验证，湿纸页可以直接达到机械脱水48-50%的极限干度，比传统的各种压榨方式的最高干度至少高2个百分点，而且节电50-70%，节约蒸汽消耗8-40%，延长毛布的使用寿命1-2倍，提高纸页的湿强度1-2倍，提高纸页的干强度至少20%，提高纸页的抄造率（减少断头）1-3个百分点，设备的造价降低到原来的1/2到1/5，大大降低制造成本，设备的维修成本降低到原来的1/5以下，设备操作更简单，工人的劳动强度和操作难度更低，由于不使用真空泵等高噪音设备，工人的操作环境大大改善。
该实施例中，压榨辊10、成型辊4的相抵点与毛布3、成型辊4的分离点是相互重合的，当然，也可将压榨辊10往前设置一点，使得压榨辊10与成型辊4的相抵点位于毛布3与成型辊4的分离点之前（此处将各个箭头所指的方向定义为后）。
实施例二：
如图8所示，为实施例二的结构示意图，该实施例与实施例一的区别在于：该实施例的毛布3与成型网2从成型辊4上全部转移至压榨辊10上，然后还设置了转移装置，该转移装置用于将成型网4上的湿纸页向毛布3上转移，这是由于压榨辊10与成型辊4之间的线压力过大会将湿纸页的部分纤维压入成型网2的网孔内，该转移装置优选为附着在成型网2背面的吹风装置11，能够将成型网2网孔内的部分纤维吹至毛布3上。当然，也可在毛布3的一侧设置吸风装置12，同样能够起到相同的作用，但这种结构容易加大毛布3与吸风装置12之间的摩擦力，造成动力消耗过大，同时还会磨损毛布3，缩短毛布3的使用寿命。
实施例三：
如图9所示，为实施例三的结构示意图，该实施例中，毛布3与成型网2从压榨辊10与成型辊4的相抵点输送出后并未立即分开，同样是通过转移装置（吹风装置11或吸风装置12）的作用后，再由毛布3将湿纸页5送出。
一般来说，纸机常规最高的脱水线压力不超过300 kgf/cm，本方案三种实施例中，压榨辊10与成型辊4之间的线压力可以设置为不小于400 kgf/cm或500kgf/cm或600kgf/cm，实现更好的脱水效果。
另外，成型网2的张力一般不超过10 kgf/cm，本方案三种实施例中，成型网2的张力可设置为不小于10kgf/cm或15kgf/cm，可以保证在压榨辊10与成型辊4之间高线压力的条件下，不破坏湿纸页。
本方案改进的新月型夹网纸机成型器结构简单、使用方便，具有较好的脱水效果和效率，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。
