技术领域
本申请涉及混合分散设备技术领域，具体涉及一种混合分散装置。
背景技术
将两种或两种以上的物料进行混合分散时，通常需要使用混合分散装置将物料分散，以获得均匀性较好的混合物，该均匀性较好的混合物对采用其制成的产品的质量是至关重要的。
然而，在相关技术中，混合分散装置靠搅拌来使物料分散，这样使得分散时间较长，并且分散效率较低。
实用新型内容
本申请提供了一种混合分散装置，能够缩短物料的分散时间以及提高物料的分散效率。
本申请提供了一种混合分散装置，包括罐体、搅拌部件、分散部件和驱动部件。罐体具有用于容纳物料的容纳腔。搅拌部件设置于容纳腔，用于混合容纳腔内的物料。分散部件设置于容纳腔，分散部件包括第一筒体及第二筒体，第一筒体具有与容纳腔连通的第一空腔，第二筒体位于第一空腔中，且第二筒体具有与容纳腔连通的第二空腔。驱动部件与搅 拌部件连接以驱动搅拌部件在容纳腔内混合物料。驱动部件还与分散部件连接以驱动第二筒体在第一空腔内相对于第一筒体转动，使容纳腔内混合的物料流入第二空腔中，并在分散部件实现分散后流出。
在上述这些实施例中，搅拌部件可在驱动部件的驱动下，搅动容纳腔内的物料进行混合，在物料混合的过程中，分散部件中的第二筒体能够被驱动部件驱动以在第一空腔内相对于第一筒体转动，该转动可使第二空腔内的压力低于外部的压力，此时，容纳腔内的物料会流入第二空腔内并在第二筒体的转动从第二空腔内甩出，甩出的物料会在第一筒体和第二筒体之间受到较大的剪切力，而且第一筒体和第二筒体能够增大物料的剪切面积，进而加速物料的分散，从而缩短物料的分散时间及提高物料的分散效率。
在本申请的一些实施例中，第一筒体的内径比第二筒体的外径大10mm-15mm。
在上述这些实施例中，能够增大进入第一筒体和第二筒体间隙中的物料所受到的剪切力，剪切力的增大会进一步加速物料的破碎和分散，从而使物料的分散时间缩短，分散效率提高。
在本申请的一些实施例中，第一筒体的侧壁沿周向方向间隔设有多个第一剪切齿，相邻两个第一剪切齿之间形成第一流出通道，第一流出通道连通于第一空腔和容纳腔之间。第二筒体的侧壁沿周向方向间隔设有多个第二剪切齿，相邻两个第二剪切齿之间形成第二流出通道，第二流出通道连通于第一空腔和第二空腔之间。
在上述这些实施例中，可使物料与第一剪切齿和第二剪切齿的壁面进行碰撞，进而实现对物料的破碎和分散，进一步提高物料分散效率。
在本申请的一些实施例中，第一流出通道的宽度小于或等于第二流出通道的宽度。
在上述这些实施例中，第一流出通道的宽度小于第二流出通道宽度，一方面，能够使物料高速流入第一筒体和第二筒体间隙中，实现对物料的剪切；另一方面，还能够使进入剪切后的物料进入至较窄的第一流出通道内，实现物料的再次剪切，从而进一步提高物料的分散效率。
在本申请的一些实施例中，第一流出通道的宽度为2mm-5mm，第二流出通道的宽度为3mm-8mm。
在上述这些实施例中，第一流出通道和第二流出通道的宽度设置，可增大流入第一筒体和第二筒体间隙中的物料流量的同时，还可提高物料的分散效率。
在本申请的一些实施例中，第一流出通道相对于第一筒体的径向方向倾斜设置。第二流出通道相对于第二筒体的径向方向倾斜设置。
在上述这些实施例中，第一流出通道和第二流出通道的倾斜设置，能够增强物料与通道壁面之间的碰撞，以加速物料的分散，从而提高分散效率。
在本申请的一些实施例中，第一剪切齿的横截面为倾斜设置的方形。第二剪切齿的横截面为倾斜设置的方形。
在上述这些实施例中，方形的倾斜设置可有助于物料快速流入通道内，以缩短分散时间。
在本申请的一些实施例中，第一剪切齿的倾斜角度为30°-45°。第二剪切齿的倾斜角度为30°-60°。
在上述这些实施例中，第一剪切齿和第二剪切齿的角度设置，能够加速物料流入流出通道内，并且还有助于物料的破碎。
在本申请的一些实施例中，第一剪切齿和第二剪切齿的横截面的倾斜方向相反。
在上述这些实施例中，这样可增强从第二筒体中流出的物料与第一筒体壁面发生碰撞的机率，以有助于物料的破碎与分散。
在本申请的一些实施例中，第二筒体包括第二筒体本体、传动件及多个支撑件。第二筒体本体具有第二空腔。传动件设置于第二空腔内，并与驱动部件连接。支撑件连接于第二筒体本体和传动件之间以使驱动部件驱动传动件带动第二筒体本体转动，相邻两个支撑件之间形成第二筒体本体的入料通道，入料通道与第二空腔连通。
在上述这些实施例中，支撑件连接于第二筒体本体和传动件之间，以起到固定连接和支撑的作用，这样可有助于第二筒体的稳定转动。此外，相邻支撑件之间形成的入料通道，可增强物料在第二筒体的轴向方向的流动，以增大被剪切的机率，从而缩短物料分散时间和提高物料分散效率。
在本申请的一些实施例中，支撑件具有导向面，导向面朝第二空腔倾斜设置。
在上述这些实施例中，导向面能够加快物料流入第二空腔内，并增强物料沿轴向方向的流动，进而增强物料被剪切的机率，进一步缩短物料分散时间及提高物料分散效率。
在本申请的一些实施例中，导向面的倾斜角度为30°-60°。
在上述这些实施例中，导向面的倾斜角度设置，能够引导物料快速流入至第二空腔内，并沿着第二筒体的轴向高速流动，以使物料之间发生碰撞及高速流出，从而增强物料的破碎和分散。
在本申请的一些实施例中，驱动部件包括第一动力源、第二动力源和行星齿轮箱。第一动力源用于提供动力来驱动第二筒体转动。第二动力源用于提供动力来驱动搅拌部件转动。行星齿轮箱的输入端分别与第一 动力源和第二动力源连接，行星齿轮箱的输出端分别与分散部件和搅拌部件连接。
在上述这些实施例中，第一动力源可提供动力来驱动第二筒体高速转动，以对流入分散部件内的物料进行剪切，提高物料的分散效率。第二动力源通过行星齿轮箱传动，以驱动搅拌部件转动，搅拌部件在公转时还可自转，这样可使物料沿轴向及四周流动，缩短物料混合的时间。
在本申请的一些实施例中，混合分散装置还包括转盘，设置于罐体内，并与行星齿轮箱的输出端传动连接。第一筒体包括第一筒体本体及连接于第一筒体本体的端部的连接轴，连接轴还与转盘连接。
在上述这些实施例中，通过第二动力源驱动转盘来带动第一筒体转动，这样可增强物料与第一筒体之间的碰撞，加速对物料的破碎和分散，进一步缩短物料的分散时间及提高物料的分散效率。

具体实施方式
下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来 限制本申请的范围，即本申请不限于所描述的实施例。
在本申请的描述中，需要说明的是，除非另有说明，“多个”的含义是两个以上；术语“上”、“下”、“左”、“右”、“内”、“外”等指示的方位或位置关系仅是为了便于描述本申请和简化描述，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申请的限制。此外，术语“第一”、“第二”、“第三”等仅用于描述目的，而不能理解为指示或暗示相对重要性。“垂直”并不是严格意义上的垂直，而是在误差允许范围之内。“平行”并不是严格意义上的平行，而是在误差允许范围之内。

均匀性较好的混合物对采用其制成的产品的质量是至关重要的，例如，在电池中，电极组件的极片上需要涂布含有活性物质、粘结剂、导电剂和溶剂的浆料，该浆料通常使用混合分散装置将浆料中的各物料进行分散，制成均匀性较好的浆料，该均匀性较好的浆料涂布于极片上时，能够有利于提高电池的电化学性能。
然而，在相关技术中，混合分散装置靠搅拌来使物料分散，发明人发现，现有的混合分散装置对粉体、高黏度、高密度等物料进行混合分散时，尤其在混合分散电池浆料中的物料时，通常需要较长时间才能使物料分散，而且分散效率较低。
鉴于此，本申请提供了一种混合分散装置，该装置包括罐体、搅拌 部件、分散部件和驱动部件。罐体具有用于容纳物料的容纳腔。搅拌部件设置于容纳腔，用于混合容纳腔内的物料。分散部件设置于容纳腔，分散部件包括第一筒体及第二筒体，第一筒体具有与容纳腔连通的第一空腔，第二筒体位于第一空腔中，且第二筒体具有与容纳腔连通的第二空腔。驱动部件与搅拌部件连接以驱动搅拌部件在容纳腔内混合物料。驱动部件还与分散部件连接以驱动第二筒体在第一空腔内相对于第一筒体转动，使容纳腔内混合的物料流入第二空腔中，并在分散部件实现分散后流出。
本申请的实施例所提到的电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池可以包括电池模组或电池包等。电池一般包括用于封装一个或多个电池单体的箱体。箱体可以避免液体或其他异物影响电池单体的充电或放电。
在本申请的一些实施例中，电池单体可以包括锂离子电池单体、锂硫电池单体、钠离子电池单体或镁离子电池单体等，也可以是一次电池或二次电池，本申请实施例对此并不限定。电池单体可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此也不限定。
电池单体包括电极组件和电解液，电极组件包括正极极片、负极极片和隔离件。电池单体主要依靠金属离子在正极极片和负极极片之间移动来工作。正极极片包括正极集流体和正极活性物质层，正极活性物质层涂覆于正极集流体的表面，负极极片包括负极集流体和负极活性物质层，负极活性物质层涂覆于负极集流体的表面。在本申请中，形成正极活性物质层和负极活性物质层的浆料可通过本申请的混合分散装置制成。
具体的，将活性物质、导电剂、粘结剂、溶剂以及其它添加剂添加至罐体的容纳腔内，通过搅拌部件的搅动，使浆料的组分混合。各组分在混合的过程中，可被吸入至分散部件中进行混合分散，分散后的混合物会再次进入容纳腔。
请参照图1至图7，本申请实施例提供的混合分散装置10包括罐体11、搅拌部件12、分散部件13和驱动部件14。罐体11具有用于容纳物料的容纳腔111。搅拌部件12设置于容纳腔111，用于混合容纳腔111内的物料。分散部件13设置于容纳腔111，分散部件13包括第一筒体131及第二筒体132，第一筒体131具有与容纳腔111连通的第一空腔1311a，第二筒体132位于第一空腔1311a中，且第二筒体132具有与容纳腔111连通的第二空腔1321a。驱动部件14与搅拌部件12连接以驱动搅拌部件12在容纳腔111内混合物料。驱动部件14还与分散部件13连接以驱动第二筒体132在第一空腔1311a内相对于第一筒体131转动，使容纳腔111内混合的物料流入第二空腔1321a中，并在分散部件13实现分散后流出。
罐体11的材质可为本领域所熟知的任何材质，例如金属、塑料等。示例性的，罐体11的材质可为铜。此外，罐体11的体积可以根据物料的体积来确定，例如物料的体积为50L，罐体11的体积可以为70L、80L等。
搅拌部件12置于容纳腔111内，可在驱动部件14的驱动下，对容纳腔111内的物料进行混合，并且搅拌部件12的搅拌速率可以通过驱动部件14控制，至于具体搅拌速率可根据物料的物理性质及体积进行调整。
分散部件13置于容纳腔111内，可在驱动部件14的驱动下，对容纳腔111内的物料进行分散。分散部件13包括第一筒体131和第二筒体132，第一筒体131和第二筒体132的筒体结构可提供足够的空间，使大量的物料在该空间内受到较大的剪切力，加速物料的破碎和分散。
驱动部件14可以设置在罐体11内，也可以设置在罐体11外，对此本申请不做具体限制。示例的，驱动部件14设置在罐体11内，并且其输出端分别与搅拌部件12和第二筒体132连接。
在上述这些实施例中，搅拌部件12可在驱动部件14的驱动下，搅 动容纳腔111内的物料进行混合，在物料混合的过程中，分散部件13中的第二筒体132能够被驱动部件14驱动以在第一空腔1311a内相对于第一筒体131转动，该转动可使第二空腔1321a内的压力低于外部的压力，此时，容纳腔111内的物料会流入第二空腔1321a内并在第二筒体132的转动从第二空腔1321a内甩出，甩出的物料会在第一筒体131和第二筒体132内受到较大的剪切力，而且第一筒体131和第二筒体132的筒体结构能够增大物料的剪切面积，进而加速物料分散，从而缩短物料的分散时间及提高物料的分散效率。
请参照图1和图2，在本申请的一些实施例中，罐体11可以包括第一罐体112和第二罐体113，第一罐体112可盖设在第二罐体113上形成容纳物料的容纳腔111，搅拌部件12和分散部件13可容纳于该容纳腔111中。
在本申请的实施例中，搅拌部件12设置于容纳腔111内，在驱动部件14的驱动下，搅拌部件12能够在容纳腔111内转动以搅拌容纳腔111内的物料，使它们均匀混合。
请参照图2，在本申请的一些实施例中，搅拌部件12包括第一搅拌桨121和第二搅拌桨122，第一搅拌桨121和第二搅拌桨122分别与驱动部件14连接。第一搅拌桨121和第二搅拌桨122在容纳腔111内转动，可缩短物料混合的时间。
示例性的，第一搅拌桨121和第二搅拌桨122可为麻花框式搅拌桨，即该搅拌桨具有多个桨叶，多个搅拌叶在驱动部件14的驱动下能够公转的同时，还可自转，这样使物料能够沿轴向及四周流动，从而可在短时间内达到均匀混合物料的效果。
在本申请的实施例中，第一筒体131可以理解为定子，第二筒体132可以理解为转子，定子和转子所具有筒体结构能够提供较大的剪切面 积以对物料进行剪切。第二筒体132在驱动部件14的驱动下可相对于第一筒体131转动，这样可将搅拌部件12搅拌混合的物料沿轴向吸入至第二空腔1321a内，吸入的物料在第一筒体131和第二筒体132内受到较大的剪切力，该较大的剪切力能够加速物料破碎和分散。
在本申请的一些实施例中，第一筒体131的内径比第二筒体132的外径大10mm-15mm。可以理解的是，第一筒体131和第二筒体132之间的间隙范围为10mm-15mm，即第一筒体131的内圆的半径比第二筒体132的外圆的半径大10mm-15mm，物料在该间隙内受到挤压及相互碰撞，能够增大物料所受到的剪切力，这样可进一步加速物料的破碎和分散，从而缩短物料的分散时间缩短，以及提高物料的分散效率。
示例性的，第一筒体131的内径可以比第二筒体132的外径大10mm、11mm、12mm、13mm、14mm、15mm。
请参照图3和图4，在本申请的一些实施例中，第一筒体131的侧壁沿周向方向间隔设有多个第一剪切齿1311b，相邻两个第一剪切齿1311b之间形成第一流出通道1311c，第一流出通道1311c连通于第一空腔1311a和容纳腔111之间。第二筒体132的侧壁沿周向方向间隔设有多个第二剪切齿1321b，相邻两个第二剪切齿1321b之间形成第二流出通道1321c，第二流出通道1321c连通于第一空腔1311a和第二空腔1321a之间。
在上述这些实施例中，第一流出通道1311c沿第一筒体131的厚度方向贯穿第一筒体131的侧壁，以连通第一空腔1311a和容纳腔111。第二流出通道1321c沿第二筒体132的厚度方向贯穿第二筒体132的侧壁，以连通第一空腔1311a和第二空腔1321a。物料流入第二空腔1321a内并跟随第二筒体132转动，在离心力的作用下，物料沿第二筒体132的径向方向被甩出，而在被甩出的过程中，物料之间也会相互摩擦和碰撞，这样 可有助于物料的破碎和分散。甩出的物料到达第二剪切齿1321b的壁面并与该壁面发生碰撞，进而能够进一步有助于物料的破碎和分散。物料继续在离心力的作用下，经第二流出通道1321c流向第一筒体131和第二筒体132的间隙内并与第一剪切齿1311b的壁面发生碰撞，而且物料在该间隙内会受到较大的剪切力，这样能够加速物料的破碎和分散，进一步提高物料的分散效率。分散后的物料经过第一流出通道1311c会再次流入容纳腔111内，并可再次流入分散部件13内进行再次分散，使物料的分散效率得到进一步提高。
在本申请的一些实施例中，第一流出通道1311c的宽度小于或等于第二流出通道1321c的宽度。
在上述这些实施例中，第一流出通道1311c的宽度小于或等于第二流出通道1321c宽度，一方面，能够使物料高速流入第一筒体131和第二筒体132间隙中，实现对物料的剪切；另一方面，还能够使进入剪切后的物料进入至较窄的第一流出通道1311c内，实现物料的再次剪切，从而进一步提高物料的分散效率。
在本申请的一些实施例中，第一流出通道1311c的宽度为2mm-5mm，第二流出通道1321c的宽度为3mm-8mm。
在上述这些实施例中，第一流出通道1311c和第二流出通道1321c的宽度设置，可增大流入第一筒体131和第二筒体132间隙中的物料流量的同时，还可提高物料的分散效率。
在本申请的一些实施例中，第一流出通道1311c相对于第一筒体131的径向方向倾斜设置。第二流出通道1321c相对于第二筒体132的径向方向倾斜设置。
在上述实施例中，第一流出通道1311c和第二流出通道1321c的倾斜设置，经过第一流出通道1311c和第二流出通道1321c的物料会在通道 内相互摩擦和碰撞，并还会与通道壁面发生摩擦和碰撞，这样可以加速物料的破碎和分散，利于提高物料的分散效率。
请参照图4，在本申请的一些实施例中，第一剪切齿1311b的横截面为倾斜设置的方形。第二剪切齿1321b的横截面为倾斜设置的方形，方形的倾斜设置能够引导物料快速经过流出通道，以缩短分散时间。
在本申请的一些实施例中，第一剪切齿1311b的倾斜角度为30°-45°。第二剪切齿1321b的倾斜角度为30°-60°。
在上述这些实施例中，第一剪切齿1311b和第二剪切齿1321b的角度设置，能够加速物料流入流出通道内的同时，还使第一剪切齿1311b和第二剪切齿1321b具有锋利的端部，这样可对物料进行高效的破碎，从而提高物料的分散效率。
示例性的，第一剪切齿1311b的横截面形状和第二剪切齿1321b的横截面形状可以为平行四边形，也可以为菱形。
在本申请的一些实施例中，第一剪切齿1311b和第二剪切齿1321b的横截面的倾斜方向相反。这样可增强从第二筒体132中流出的物料与第一筒体131壁面发生碰撞的机率，以有助于物料的破碎与分散。
请参照图5，在本申请的一些实施例中，第二筒体132包括第二筒体本体1321、传动件1322及多个支撑件1323。第二筒体本体1321具有第二空腔1321a。传动件1322设置于第二空腔1321a内，并与驱动部件14连接。支撑件1323连接于第二筒体本体1321和传动件1322之间以使驱动部件14驱动传动件1322带动第二筒体本体1321转动，相邻两个支撑件1323之间形成第二筒体本体1321的入料通道，入料通道与第二空腔1321a连通。
示例性的，传动件1322位于第二筒体本体1321的中心，支撑件1323的一端连接于第二筒体本体1321的端部，另一端连接于传动件 1322。当驱动部件14驱动传动件1322带动第二筒体本体1321旋转时，第二空腔1321a内形成负压，可将容纳腔111内的物料经入料通道吸入至第二空腔1321a内。
在上述这些实施例中，第二筒体本体1321中至少一端部连接有支撑件1323，该支撑件1323能够起到固定连接和支撑的作用，从而有助于第二筒体本体1321的稳定转动。此外，相邻支撑件1323之间形成的入料通道，可增强物料在第二筒体本体1321的轴向方向的流动，以增大被剪切的机率，从而缩短物料分散时间和提高物料分散效率。
在本申请的一些实施例中，支撑件1323具有导向面，导向面朝第二空腔1321a倾斜设置。导向面能够加快物料流入第二空腔1321a内，并增强物料沿轴向方向的流动，进而增强物料被剪切的机率，进一步缩短物料分散时间及提高物料分散效率。
在本申请的一些实施例中，导向面的倾斜角度为30°-60°。
在上述这些实施例中，导向面的倾斜角度设置，能够引导物料快速流入至第二空腔内，并沿着第二筒体的轴向高速流动，以使物料之间发生碰撞及高速流出，从而增强物料的破碎和分散。
请参照图6，在本申请的一些实施例中，驱动部件1414包括第一动力源141、第二动力源142和行星齿轮箱143。第一动力源141用于提供动力来驱动第二筒体132转动。第二动力源142用于提供动力来驱动搅拌部件12转动。行星齿轮箱143的输入端分别与第一动力源141和第二动力源142连接，行星齿轮箱143的输出端分别与分散部件13和搅拌部件12连接。第一动力源141可提供动力来驱动第二筒体132高速转动，以对流入分散部件13内的物料进行剪切，提高物料的分散效率。第二动力源142通过行星齿轮箱143传动，以驱动搅拌部件12转动，搅拌部件12在公转时还可自转，这样可使物料沿轴向及四周流动，缩短物料混合的时间。
本申请实施例对第一动力源141和第二动力源142不做具体限制，可为本领域所熟知的动力装置，例如电机。
本申请实施例对行星齿轮箱143不做具体限制，可为本领域熟知的减速装置。示例性的，行星齿轮箱143包括减速器1431、中心轴1432、太阳轴1433、太阳轮1434、行星轴1435、行星轮1436。减速器1431的输入端分别于第一动力源141和第二动力源142连接，其输出端与中心轴1432和太阳轴1433连接。中心轴1432位于太阳轴1433内，并通过传动件1322与第二筒体132连接。太阳轮1434与太阳轴1433连接，并与行星轮1436啮合。行星轮1436与行星轴1435连接，行星轴1435与搅拌部件12连接。
请参照图6和图7，在本申请的一些实施例中，混合分散装置10还包括转盘15，该转盘15设置于罐体11内，并与行星齿轮箱143的输出端传动连接。第一筒体131包括第一筒体本体1311及连接于第一筒体本体1311的端部的连接轴1312，第一筒体本体1311具有第一空腔1311a，连接轴1312还与行星齿轮箱143的输出端连接，即连接轴1312与行星轴1435连接。通过第二动力源142驱动第一筒体本体1311转动，这样可增强物料与第一筒体本体1311之间的碰撞，加速对物料的破碎和分散，进一步缩短物料的分散时间及提高物料的分散效率。
在本申请的一些实施例中，混合分散装置10包括罐体11、搅拌部件12、分散部件13和驱动部件14。罐体11具有用于容纳物料的容纳腔111。搅拌部件12设置于容纳腔111，用于混合容纳腔111内的物料。分散部件13设置于容纳腔111，分散部件13包括第一筒体131及第二筒体132，第一筒体131具有与容纳腔111连通的第一空腔1311a，第二筒体132位于第一空腔1311a中，且第二筒体132具有与容纳腔111连通的第二空腔1321a，第一筒体131的内径比第二筒体132的外径大10mm-15mm。 驱动部件14在驱动搅拌部件12转动的同时，还可以驱动第二筒体132在第一空腔1311a内相对于第一筒体131转动，使容纳腔111内混合的物料在第一筒体131和第二筒体132的间隙中受到较大的剪切力，加速物料的破碎和分散，从而缩短物料的分散时间缩短，以及提高物料的分散效率。
