实用新型内容
为了克服现有技术的不足，本实用新型的目的在于提供循环捏合式制浆系统，其能够对浆料进行充分地捏合，以提高浆料的捏合效果。

具体实施方式
下面，结合附图以及具体实施方式，对本实用新型做进一步描述，需要说明的是，在不相冲突的前提下，以下描述的各实施例之间或各技术特征之间可以任意组合形成新的实施例。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上，或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能存在居中元件。本文所使用的 “垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的，并不代表是唯一的实施方式。
除非另有定义，本文所使用的所有的技术术语和科学术语与属于本实用新型的技术领域的技术人员通常理解的含义相同。本文中在实用新型的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本实用新型。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
图1-图2示出了本实用新型一较佳实施例的循环捏合式制浆系统，包括制浆机1和捏合罐2。制浆机1具有粉末进料口11、与粉末进料口11连通的制浆腔12、与制浆腔12连通的浆料出口13。制浆机1的螺杆14穿设于制浆腔12；制浆机1的浆料出口13通过第一管道31与捏合罐2的捏合进口连通，捏合罐2设有液体溶剂进口，捏合罐2的捏合出口通过第二管道32与制浆机1的循环制浆入口16连通。
工作时，将粉末从粉末进料口11送入制浆机1内，当粉末被螺杆14沿第一管道31推送到捏合罐2内时，向捏合罐2的溶剂进口注入液体溶剂，然后启动捏合罐2(例如常规的螺带捏合罐2)将粉末物料与液体溶剂进行充分地捏合而形成浆料，然后，在螺杆14的持续推力下，从捏合罐2出来的浆料沿第二管道32进入循环制浆入口16，然后使得浆料被循环地搅拌、捏合，从而形成高固含量的浆料，以提高捏合效果。
显然，通过制浆机1与捏合罐2之间进行外循环，从而能够将粉末物料与液体溶剂进行充分地捏合，以提高浆料的固含量。而且，通过制浆机1的螺杆14作为动力源对浆料进行搅拌和推进，从而还将其作为浆料的进行外循环捏合的动力源，一物两用。特别是，传统的利用螺杆14进行离心排料的原理只适合 中低固含量物料的捏合，无法实现高固含量物料的捏合；而基于制浆机1的螺杆14将高固含量的浆料往复地送入捏合罐2，从而能够对浆料进行稀释，解决了高固含量的浆料流经后续的分散腔15时引起的堵塞问题。
优选地，制浆机1具有分散腔15，分散腔15容置有分散定子151和分散转子152，分散转子152与制浆机1的螺杆14传动连接；如此，利用螺杆14的动力同时对分散转子152进行驱动，从而可以节省动力源的数量。循环捏合式制浆系统还包括分散罐4(其中，分散罐4属于成熟产品，其内部也设有用于分散浆料的定子和转子)，分散罐4的循环分散出口41通过第三管道33与分散腔15的入口连通，分散腔15的出口通过第四管道34与分散罐4的循环分散入口42连通。捏合罐2的捏合出口连接有第五管道35，第五管道35通过第一分流三通管连接在第三管道33的两端之间；第三管道33连接有循环泵5。需要说明的是，分散阶段位于捏合阶段之后，即当捏合结束之后，再进行浆料的分散，以提高浆料的性能。这样设置，分散腔15与分散罐4之间在循环泵5的作用下可以进行外循环，其过程为：第三管道33→分散腔15→第四管道34→分散罐4→第三管道33。如此，可以利用分散腔15与分散罐4的双分散区对将来进行充分地分散，进一步提高了对浆料的分散效率。
优选地，捏合罐2的捏合出口通过第二分流三通管分别连接第二管道32和第五管道35。这样设置，可以避免在捏合罐2开设更多的开口。此时，最好地，第二管道32连接有第一阀门61，第五管道35连接有第二阀门62。当在循环进行的捏合阶段中，将第一阀门61开启，第二阀门62关闭，从而避免浆料进入第三管道33。当在循环进行的分散阶段中，第一阀门61关闭，第二阀门62开启，从而避免浆料沿第二管道32再次进入捏合罐2，以利于捏合罐2将其内部的浆料干净排入第三管道33；待第一管道31、第二管道32和捏合罐2均尽量 (此时可以利用气体负压原理)排干净浆料后，再将第二阀门62也同时关闭，然后继续分散阶段的循环即可。
优选地，第三管道33连接有第三阀门63和排料阀门64，第三阀门63位于第一分流三通管与分散罐4之间，排料阀门64与第三阀门63之间通过第三分流三通管连接。这样设置，当浆料捏合结束以及分散结束之后，通过关闭第三阀门63和开启排料阀门64，即可以将浆料从分散罐4更彻底地排出。
为了使得本循环捏合式制浆系统自带粉末进料组件7，优选地，循环捏合式制浆系统还包括粉末进料组件7，粉末进料组件7包括多个相互独立的主料仓71、多个相互独立的辅料仓72、集料漏斗73、控制阀74和旋转下料阀75，各主料仓71和各辅料仓72均与集料漏斗73连通，集料漏斗73、控制阀74门、旋转下料阀75、制浆机1的粉末进料口11依序连接。优选地，各主料仓71和各辅料仓72均安装有第一失重秤76。其中，旋转下料阀75无法关闭，但可以调节进料的开口大小，从而控制粉末物料的进料速度。
为了使得本循环捏合式制浆系统自带溶剂进料组件8，优选地，循环捏合式制浆系统还包括溶剂进料组件8，溶剂进料组件8包括多个液体罐81，液体罐81连接有第二失重秤82或质量流量计83，各液体罐81均与捏合罐2连接。优选地，各液体罐81均连接有抽吸泵84。
优选地，所述制浆机1设有冷却腔9，所述冷却腔9环绕在所述制浆腔12的外围，通过对制浆机1进行冷却，从而避免浆料高温而损坏。
上述实施方式仅为本实用新型的优选实施方式，不能以此来限定本实用新型保护的范围，本领域的技术人员在本实用新型的基础上所做的任何非实质性的变化及替换均属于本实用新型所要求保护的范围。
