本申请技术方案,具有如下优点:
1.本申请提供的离心式分散装置,多个定子单元和多个转子单元相互穿插安装在筒体内,转子内筒固定套设于轴芯上随所述轴芯转动,转子内筒和转子外筒在转子筋板的至少一侧形成有转子腔,转子外筒的筒壁上开设有多个与转子腔相通的过流孔;定子筒体的内壁和转子外筒的外壁之间形成有第一过流通道,第一过流通道与多个过流孔连通,当浆料从螺杆挤出装置挤出流进筒体,浆料流进转子腔内时,由于转子单元随着轴芯转动,在离心力作用下,浆料向转子外筒的内壁贴合挤压,即浆料流经过流孔,充满浆料的过流孔内在浆料流动下产生局部压力变化,局部压力变化会发散到过流孔的周围,从而带动浆料做不规则运动,以达到将浆料进行初步的整体分散;而且浆料在过流孔形成紊流,可对浆料进一步分散;浆料经过转子外筒上的过流孔分散后流向第一过流通道,转子单元转动过程中,转子单元和定子单元的相对运动,使得第一过流通道内产生较大的剪切力,以对第一过流通道内的浆料进行二次剪切分散。浆料从第一过流通道沿轴线向后流动。该离心式分散装置,具有较强的分散能力,可实现浆料的快速分散,提高浆料的分散效率。
2.本申请提供的离心式分散装置,隔挡部的相对两侧壁和对应的转子外筒的侧壁之间形成有第二过流通道,隔挡部朝向轴芯的内壁和转子内筒的外壁之间形成有第三过流通道;第一过流通道、第二过流通道和第三过流通道依次连通,第三过流通道连通对应的隔挡部两侧的两条第二过流通道。在隔挡部的作用下,浆料依次流经第二过流通道和第三过流通道,进入下一个转子单元被离心分散。
3.本申请提供的离心式分散装置,设于两个转子单元之间的隔挡部对位于转子腔内的浆料进行隔档,避免转动过程中浆料从转子腔的腔口流出,使得浆料贴合转子外筒,此外,隔挡部对浆料的流动形成湍流,使得部分浆料回流至第一过流通道内被再次剪切分散,提高浆料的分散度。隔挡部有效的提高了该离心式分散装置的分散能力,可使得浆料充分分散。
4.本申请提供的离心式分散装置,转子外筒在转子筋板的相对两侧均形成有转子腔,转子外筒对应两侧的两个转子腔的壁面上均设有过流孔,浆料在相对前端的转子腔经过离心分散后进去第一过流通道内被再次剪切分散,浆料在第一过流通道内沿轴线后侧流动,收到隔挡部的阻挡后,形成湍流,部分回流至第一过流通道,部分沿第二过流通道流动,相对后侧的转子腔的开口与第二过流通道连通,部分浆料进入相对后侧的转子腔内被再次离心分散,重新进入第一过流通道。转子筋板的相对两侧均形成转子腔,使得浆料可被往复离心分散,可使得浆料被充分分散,有效的提高了离心分散的效率。

参照图1至图4所示,本申请提出的一种离心式分散装置,包括:筒体1、多个转子单元2和多个定子单元3;筒体1与螺杆挤出装置的出料端连通,筒体1内设有受驱动件5驱动转动的轴芯4;转子单元2包括转子内筒21、转子外筒22和连接在转子内筒21和转子外筒22之间的转子筋板23,转子内筒21固定套设于轴芯4上随轴芯4转动,转子内筒21和转子外筒22在转子筋板23的至少一侧形成有转子腔6,转子外筒22的筒壁上开设有多个与转子腔6相通的过流孔221。
多个定子单元3和多个转子单元2在轴芯4的轴向方向上交替设置,定子单元3包括与筒体1内壁固定连接的定子筒体30和由定子筒体30的内壁伸向相邻两个转子单元2之间间隙处的隔挡部31。
定子筒体30的内壁和转子外筒22的外壁之间形成有第一过流通道7,第一过流通道7与多个过流孔221连通;隔挡部31的相对两侧壁和对应的转子外筒22的侧壁之间形成有第二过流通道8,隔挡部31朝向轴芯4的内壁和转子内筒21的外壁之间形成有第三过流通道9,第一过流通道7、第二过流通道8和第三过流通道9依次连通,第三过流通道9连通对应的隔挡部31两侧的两条第二过流通道8。
具体说明,多个定子单元3和多个转子单元2在轴芯4的轴向方向上交替设置,转子内筒21固定套设于轴芯4上随轴芯4转动,转子内筒21和转子外筒22在转子筋板23的至少一侧形成有转子腔6,转子外筒22的筒壁上开设有多个与转子腔6相通的过流孔221;定子筒体30的内壁和转子外筒22的外壁
之间形成有用于对浆料进行剪切的第一过流通道7,第一过流通道7与多个过流孔221连通。
隔挡部31的相对两侧壁和对应的转子外筒22的侧壁之间形成有用于对浆料进行剪切的第二过流通道8,隔挡部31朝向轴芯4的内壁和转子内筒21的外壁之间形成有用于对浆料进行剪切的第三过流通道9;第一过流通道7、第二过流通道8和第三过流通道9依次连通,第三过流通道9连通对应的隔挡部31两侧的两条第二过流通道8。
可以理解的是,当浆料从螺杆挤出装置挤出流进筒体1,浆料流进转子腔6内时,由于转子单元2随着轴芯4转动,在离心力作用下,浆料向转子外筒22的内壁贴合挤压,即浆料流经过流孔221,充满浆料的过流孔221内在浆料流动下产生局部压力变化,局部压力变化会发散到过流孔221的周围,从而带动浆料做不规则运动,以达到将浆料进行初步的整体分散;而且浆料在过流孔221形成紊流,可对浆料进一步分散;浆料经过转子外筒22上的过流孔221分散后流向第一过流通道7,浆料流动到第一过流通道7后,定子筒体30对从过流孔221内流出的浆料进行隔挡,使得部分浆料产生回流,浆料会往复流经过流孔221,多个过流孔221之间可以形成密集的对流,快速完成对浆料的初步分散;
转子单元2转动过程中,转子单元2和定子单元3的相对运动,使得第一过流通道7内产生较大的剪切力,以对第一过流通道7内的浆料进行二次剪切分散。浆料从第一过流通道7沿轴线向后流动,在隔挡部31的作用下,浆料依次流经第二过流通道8和第三过流通道9,进入下一个转子单元2被离心分散。该离心式分散装置,具有较强的分散能力,可实现浆料的快速分散,提高浆料的分散效率。
需要说明,转子外筒22的筒壁上开设有多个与转子腔6相通的过流孔221,过流孔221的数量、形状以及尺寸大小不作为本申请的限制过流孔221的尺寸越小,其离心分散的能力越强,但分散效率会越慢;该分散孔可沿转子外筒22的筒壁周向均匀布设,或不规则分布。
定子单元3和转子单元2交替设置,定子单元3和转子单元2的具体数量可根据实际应用时通入的浆料决定,定子单元3和转子单元2组数的增加可增强分散能力,在本申请的一些实施例中,采用三个定子单元3搭配三个转子单元2的结构,转子单元2和定子单元3的具体数量不作为本申请的限制。
参照图3所示,在本申请的一些实施例,在轴芯4的径向方向上,隔挡部
31的内壁和定子筒体30的内壁之间的间距大于转子外筒22的内壁和定子筒体30的内壁之间的间距。
具体说明,浆料由于离心力会优先贴合转子外筒22的内壁,所以浆料在流经第三过流通道9进入下一个转子单元2之前,浆料会自动填充满隔挡部31内壁以外的区域,即浆料会完全淹没转子单元2上所有的过流孔221,实现对浆料的充分离心分散。设于两个转子单元2之间的隔挡部31对位于转子腔6内的浆料进行隔档,避免转动过程中浆料从转子腔6的腔口流出,使得浆料贴合转子外筒22,此外,隔挡部31对浆料的流动形成湍流,使得部分浆料回流至第一过流通道7内被再次剪切分散,提高浆料的分散度。隔挡部31有效的提高了该离心式分散装置的分散能力,可使得浆料充分分散。
在本申请的一些实施例中,第一过流通道7和第三过流通道9的流向与轴芯4的轴线方向同向,第二过流通道8的流向与轴芯4的轴线方向垂直。
在本申请的一些实施例中,第一过流通道7的宽度为2-3mm。
具体说明,第一过流通道7的宽度即转子外筒22的外壁与定子筒体30的内壁之间的间距,当该间距越小即第一过流通道7的宽度越窄时,第一过流通道7内的剪切力就越大,转子单元2的转动速度越慢。剪切力越大,浆料的分散度就越高,转子单元2的转速越慢,浆料的分散效率就越慢。在本申请的一些实施例中,第一锅通道的宽度设置在2-3mm,转子单元2的分散速度为10-30m/s。
需要说明,转子单元2的分散速度可调,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2的转速,以匹配不同浆料对剪切分散效率的要求,转子单元2的转速调节方式可以通过PLC控制器改变驱动件5的转速的方式进行调节,转子单元2的转速调节方式不作为本申请的限制。
可根据通入浆料的性质,对转子单元2和定子单元3的规格尺寸进行更换,以实现对第一过流通道7宽度大小的更改。
参照图4所示,在本申请的一些实施例中,转子腔6为以转子筋板23为腔体底壁、以转子内筒21的外壁为腔体内周壁、以转子外筒22的内壁为腔体外周壁、且背向转子筋板23一端为敞口的腔体结构,转子腔6与第二过流通道8和第三过流通道9均直接相通。
在本申请的一些实施例,转子筋板23一体成型于转子内筒21和转子外筒22的中部,转子筋板23的相对两侧均形成有转子腔6,对应两个转子腔6的转
子外筒22上均设有过流孔221。
具体说明,转子外筒22在转子筋板23的相对两侧均形成有转子腔6,转子外筒22对应两侧的两个转子腔6的壁面上均设有过流孔221,浆料在位于转子筋板23前端的的转子腔6内经过离心分散后进去第一过流通道7内被再次剪切分散,浆料在第一过流通道7内沿轴线后侧流动,受到隔挡部31的阻挡后,形成湍流,部分回流至第一过流通道7,部分沿第二过流通道8流动,位于转子筋板23后端的转子腔6的开口与第二过流通道8连通,部分浆料进入相对后侧的转子腔6内被再次离心分散,重新进入第一过流通道7。转子筋板23的相对两侧均形成转子腔6,使得浆料可被往复离心分散,可使得浆料被充分分散,有效的提高了离心分散的效率。
可以理解,转子腔6内为光滑无死角的腔体,避免了浆料在死区内堆积,影响浆料的分散和流动。
在本申请的一些实施例中,过流孔221有多个,多个过流孔221沿转子外筒22的周向均匀间隔布置。
具体说明,过流孔221沿转子外筒22的周向均匀间隔布置多个,使得当转子单元2转动时,使得浆料从转子腔6内被分散出去,多个过流孔221可以形成密集的对流,快速完成对浆料的分散。过流孔221的形状可为圆形或椭圆形或方形,过流孔221的具体形状不作为本申请的限制。
根据本申请的一些实施例,筒体1端口处设有适于与螺杆挤出装置连接的前端板11,前端板11通过紧固件与螺杆挤出装置的外筒密封连接。
具体说明,筒体1密封连接在螺杆挤出装置出料端的端板上。具体的,筒体1的一端固定设有前端板11,筒体1的前端板11和螺杆挤出装置出料端通过多个连接螺栓固定连接。前端板11和螺杆挤出装置出料端之间的连接面上设有密封部件,如此设置,不仅可以保证筒体1和螺杆挤出装置连接处的良好密封,防止出现浆料泄漏;而且结构简单、安装方便,有利于缩短螺杆挤出装置末端和转子单元2之间的间隔,避免因间隔过长导致浆料出现局部沉降而影响浆料产品质量的问题。
根据本申请的一些实施例,筒体1靠近浆料出口的一侧设置有后端板12,驱动件5与后端板12密封连接,驱动件5为电机,电机的输出端上连接有伸向筒体1内的主轴51,轴芯4连接在主轴51的外周,筒体1和主轴51密封连接。
具体说明,驱动件5为电机,电机的输出端上连接有伸向筒体1内的主轴
51,轴芯4与主轴51的外周固定连接,随着主轴51转动,筒体1和主轴51密封连接。具体的,筒体1的后端板12和主轴51的连接处设有密封结构,密封结构可以防止浆料从筒体1和主轴51连接处的缝隙向外泄漏。
可以理解的是,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,介质换热通道环绕筒体1的周壁螺旋设置。具体的,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。
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。
