此外，下面所描述的本申请不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
参照图1至图7所示，本申请提出的一种剪切分散装置，包括：筒体1、定子单元2和转子单元3；筒体1，连接在螺杆挤出装置的出料端上，所述筒体1内设有受驱动件驱动转动的轴芯4；定子单元2，数量为多个，所述定子单元2套设于所述轴芯4上，所述定子单元2与所述筒体1固定连接，所述定子单元2设有沿自身轴向方向贯通所述定子单元2的第一通孔221；转子单元3，数量为多个，所述转子单元3固定套设于所述轴芯4上，多个所述定子单元2和多个所述定子单元2沿所述轴芯4的轴向方向上交替设置，所述转子单元3设有沿自身轴向方向贯通所述转子单元3的第二通孔321；所述转子单元3随所述轴芯4转动，以使得多个所述第一通孔221和多个所述第二通孔321交错互通以形成对浆料进行剪切分散的第一通道。
具体说明，定子单元2和转子单元3交替安装在筒体1内，转子单元3固定套设于轴芯4上，定子单元2沿其自身轴向开设有多个第一通孔221，转子单元3沿其自身轴向开设有多个第二通孔321，驱动件驱动轴芯4转动时带动转子单元3转动，使得多个第一通孔221和多个第二通孔321交错互通，转子单元3相对于定子单元2转动，第一通孔221和第二通孔321连通处形成较大的剪切力，浆料从第一通孔221流向第二通孔321的过程中，被剪切分散，以提高浆料的分散度；多个定子单元2和多个转子单元3交替设置，轴芯4带动转子单元3转动，从而使得第一通孔221和第二通孔321形成的第一通道始终保持连通状态，对浆料进行剪切的同时推进浆料的流动，实现快速且持续制浆的目的，提高制浆效率。
参照图4和图5所示，可以理解的是，第一通孔221的数量与第二通孔321的数量一致时，转子单元3转动过程中，第一通孔221的投影和第二通孔321的投影具有相互重合的状态，以便于浆料的流动，当第一通孔221的数量与第二通孔321的数量不等时，转子单元3转动过程中，至少有一个第一通孔221与一个第二通孔321的投影相互重合。第一通孔221和第二通孔321的具体数 量不作为本申请的限制。
具体说明，为使得固体含量高的浆料可以被充分剪切分散，将第一通孔221和第二通孔321设置为扇形，转子单元3转动过程中，横截面为扇形的第一通孔221或第二通孔321的半径对浆料进行剪切，有利于提高浆料的剪切效率。第一通孔221和第二通孔321的横截面形状不作为本申请的限制，还可设置为方形或三角形。
参照图3和图5所示，在本申请的一些实施例中，定子单元2包括定子外环21、定子内环23，以及多条由定子外环21沿其径向延伸至定子内环23的定子筋条22，定子外环21与所述筒体1内壁固定连接，多条定子筋条22沿定子外环21的周向均匀布设，所述第一通孔221至少由两条相邻所述定子筋条22、定子外环21和定子内环23围合而成。在芯轴4的轴向方向上，定子内环23和定子筋条22的厚度相同且均小于定子外环21的厚度。
参照图6所示，具体说明，筒体1上设有至少一个第一定位键11，定子外环21的外周壁上设有与第一定位键11相配合的第一定位槽211；第一定位槽211和第二定位槽311的数量均可为多个，第一定位槽211和第二定位槽311的具体数量不作为本申请的限制。
定子单元2通过键槽配合的方式固定在筒体1上，具体的，筒体1上设置至少一个第一定位键11，转子外环33上设置至少两个可与第一定位键11相配合的第一定位槽211；第一定位键11可与任一个第一定位槽211相互配合，可提高定子单元2安装的适配度，降低安装难度。可与通过调节第一定位键11和两个第一定位槽211之间的安装位置，使得各个定子单元2上的第一通孔221位于同一轴线上，或使得各个定子单元2上的第一通孔221错位分布，以改变剪切分散装置的分散性能。
转子单元3包括转子内环31、转子外环33，以及多条由转子内环31沿其径向延伸至转子外环33的转子筋条32，转子内环31固定套设于轴芯4上，多条转子筋条32沿转子内环31的周向均匀布设，第二通孔321至少由两条相邻所述转子筋条32、转子内环31和转子外环33围合而成。在芯轴4的轴向方向上，转子外环33和转子筋条32的厚度相同且均小于转子内环31的厚度。
参照图7所示，转子单元3同样通过键槽配合的方式固定在轴芯4上，具体地，轴芯4上设置至少一个第二定位键41，转子内环31的内壁上设有与第二定位键41相配合的第二定位槽311。通过键槽配合的方式将定子单元2固定 在筒体1上，以及将转子单元3固定在轴芯4上，便于定子单元2和转子单元3的拆卸，缩短装配时间，提高装配效率。
具体说明，多个转子单元3同向依次套设于轴芯4上，转子筋条32和定子筋条22依次相互穿插，即定子筋条22延伸至两个相邻转子筋条32之间，转子筋条32延伸至两个相邻的定子筋条22之间，当转子单元3转动过程中，转子筋条32相对于定子筋条22转动，以使得转子筋条32和定子筋条22之间形成较大的剪切力。当浆料的固体含量较高时，浆料以高流速流经第一通孔221和第二通孔321的过程中，定子筋条22和转子筋条32会对浆料进行剪切打散，以降低浆料的粘稠度。在本申请中，第一通孔221、第二通孔321、定子筋条22和转子筋条32的设置有利于提高固体含量较高的浆料的分散度，降低浆料的粘稠度。
参照图2至图5所示，在本申请的一些实施例中，定子单元2和转子单元3相对设置，转子筋条32和定子筋条22沿芯轴4的轴向方向依次间隔布置，转子内环31加厚的部分与定子内环23对应设置，定子外环21加厚的部分与转子外环33对应布置。定子外环21的内壁和转子外环33的外壁之间形成有第一轴向通道6，转子内环31的外壁和定子内环23的内壁形成有第二轴向通道8，第一轴向通道6和第二轴向通道8的流向与轴芯4的轴线方向一致；转子筋条32的相对两侧壁和定子筋条22的侧壁之间形成有径向通道7，径向通道7的流向与轴芯4的轴线方向相互垂直；第一轴向通道6、径向通道7和第二轴向通道8依次连通以形成对物料进行剪切分散的第二通道。第二轴向通道8连通定子筋条22相对两侧的两个径向通道7。
具体说明，具体说明，浆料被螺杆挤出装置挤出后，部分浆料从筒体1的前端口进入转子外环33的外周壁与定子外环21的内壁之间的第一轴向通道6，轴芯4带动转子单元3转动，浆料在第一轴向通道6内被剪切分散，沿轴芯4轴线方向向后流动，转子筋条32对浆料进行隔挡，使得浆料沿径向流动，进入径向通道7后，部分浆料通道流入第一通道内，部分沿着径向流动，在径向通道7内被剪切分散后，沿着轴芯4轴线方形向后流动，进入转子内环31的外壁与定子外环21的外壁之间的第二轴向通道8内。由第一轴向通道6、径向通道7和第二轴向通道8连通组成的第二通道呈折线形，延长了浆料的流动距离，增加分散面积，从而达到提升浆料分散度的目的，提高分散效率。
可以理解的是，定子筋条22和转子筋条32的延伸长度一致，当定子筋条 22和转子筋条32的延伸长度越长时，转子单元3随轴芯4转动过程中，转子筋条32与定子筋条22之间的径向通道7内的剪切力就越强，转子单元3所受到的阻力就越大。剪切力越强，浆料的分散度就越高；阻力越大，转子单元3的转动速度就越小，浆料的分散度就越低。在本申请的一些实施例中，将转子单元3的线速度控制在20m/s以上，以保证能够产生较大的剪切力，使浆料得以充分分散。
转子单元3的线速度可调，在实际应用中，可以根据浆料的组分、黏度等特性，调节转子单元3的转速，以匹配不同浆料对剪切分散效率的要求，转子单元3的转速调节方式可以通过PLC控制器改变驱动件的转速的方式进行调节，转子单元3的转速调节方式不作为本申请的限制。
在本申请的一些实施例中，径向通道7的宽度可调，且其宽度调节范围为1-4mm。
在本申请的一些实施例中，还包括调节垫圈，转子内环31的至少一个侧面上设有容置槽，调节垫圈套设于轴芯4上且位于容置槽内，调节垫圈适于调节径向通道7的宽度。
具体说明，通过在转子的至少一个侧面上设有容置槽，在容置槽内安装调节垫圈，通过更换调节垫圈的厚度对径向通道7进行宽度调整；在本申请的一些实施例中，还可以可选择放置多个调节垫圈进行调节，多个调节垫圈的总厚度为1.2mm-4.2mm，当容置槽的槽深等于0.2mm时，即径向通道7在宽度调节范围为1mm-4mm。容置槽的槽深和调节垫圈的厚度不作为本申请的限制，因此径向通道7的宽度调节范围也不作为本申请的限制。
可以理解的是，可在转子内环31的一侧设置容置槽，或转子内环31的两侧面均可设置容置槽，容置槽的数量不作为本申请的限制。
在本申请的一些实施例中，还包括固定件5，固定件5包括套设于轴芯4上且与位于筒体1前端口的转子内环31抵接的垫片51，以及与轴芯4连接以适于将垫片51固定在转子内环31上的紧固件52。
在本申请的一些实施例中，转子内环31朝向筒体1前端的侧面设有限位槽，垫片51与限位槽的槽底抵接。
具体说明，靠近筒体1前端的转子单元3通过固定件5与轴芯4固定连接，轴向分布的多个转子单元3的转子内环31相互抵接挤压固定，以保证转子单元3转动时不会发生晃动。固定件5具体为套设于轴芯4上，且与位于筒体1前 端的转子单元3抵接的垫片51，该垫片51置于转子单元3的限位槽内，通过紧固件52与轴芯4连接将垫片51固定在转子单元3上。紧固件52具体为螺栓。垫片51的设置在于避免轴芯4转动过程中，紧固件52与转子单元3之间发生磨损，通过垫片51作为缓冲件，避免转子单元3的损耗，降低维护成本。
可以理解的是，根据通入浆料的特性，可以选择不同的定子单元2和转子单元3数量进行装配，具体的，定子单元2数量为n个时，转子单元3数量为n+2个，以保证转子单元3位于轴芯4的两端，便于对转子单元3的固定，在本申请的一些实施例中，定子单元2为9个，转子单元3为11个。定子单元2和转子单元3的具体数量不作为本申请的限制。
可以理解的是，限位槽设置在转子内环31朝向筒体1前端的侧面上，限位槽的槽底与垫片51抵接，限位槽的槽深与垫片51的厚度一致。垫片51可选用金属等材质制成，垫片51的具体材质不作为本申请的限制。
当只在转子内环31的一侧设置容置槽，位于筒体1前端的转子单元3的转子内环31靠近前端口的侧面设置限位槽，背离前端口的另一侧面设置容置槽；当转子内环31的两侧面均设置容置槽时，位于筒体1前端的转子单元3的转子内环31的限位槽与容置槽重合。
在本申请的一些实施例中，筒体1的筒壁上设有介质换热通道，介质换热通道具有介质入口和介质出口。
具体说明，介质换热通道环绕筒体1的周壁螺旋设置。具体地，介质换热通道为冷媒通道，冷媒介质从介质入口进入经过冷媒通道后从介质出口流出，冷媒介质可以带走筒体1的一部分热量，以对筒体1内浆料进行降温。或者，介质换热通道为热媒通道，热媒介质从介质入口进入经过热媒通道后从介质出口流出，热媒介质可以对筒体1内浆料进行加热。
这种剪切分散装置，一方面在定子单元2上开设多个第一通孔221，在转子单元3开设多个第二通孔321，第一通孔221和第二通孔321构成第一通道；另一方面在定子单元2和转子单元3之间形成由第一轴向通道6、径向通道7和第二轴向通道8连通组成的第二通道；在剪切高固含量的浆料时，芯轴4带动转子单元3转动，转子单元3上的转子筋条32对浆料进行剪切后，被打散的浆料从转子单元3的不同第二通孔321穿过转子单元3，穿过的浆料接触下一片定子单元2，高速旋转的浆料碰撞到静止不动的定子单元2后，定子筋条22再次对浆料形成剪切分散，之后浆料再通过定子单元2的第一通孔221穿过定 子单元2，穿过的浆料接触接触到第二片转子单元3，后续的分散过程与前面的相同，即浆料从装置入口进入，从装置出口流出的过程里，会被打散到不同的通道里，而这些通道本身又是高速转动的，转动过程中，浆料的通道会有断开、连通来回转变的过程，并且由于电机转速高，通道转换频率快，会对浆料形成高速分散作用，这样高固含量的浆料被剪切分散后黏度下降，黏度下降后的浆料受到离心力的作用会流向狭窄的呈折线形的第二通道进一步进行剪切分散，最终得到成品浆料，如此可以大大提高装置剪切分散浆料的速率，实现浆料的连续化生产。
本申请提出的一种连续制浆设备，其特征在于，包括螺杆挤出装置和上述剪切分散装置，螺杆挤出装置包括挤出筒体1和设于挤出筒体1内的螺杆挤出元件，筒体1与挤出筒体1的出料端对接。
具体说明，本申请提出的连续制浆设备，通过与剪切分散装置连通，实现持续制浆的目的，提高制浆效率，增大制浆产量。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
