Description

一种粘性流体混合搅拌的机械装置 技术领域
本发明涉及流体机械设备技术领域，特别是一种粘性流体混合搅拌的机械装置。
背景技术
随着工业的发展，粘性流体的混合广泛应用于高分子化学、石油化工、生物工程、能源工程和食品工业等领域，但不同粘性流体在搅拌罐中呈现出不同的复杂流动情况，致使其搅拌问题仍是化工工业中的一大难题。
高粘度流体的搅拌与低粘度搅拌相比由于粘度高，动力消耗大，提高转速会导致能量消耗过大，使得桨叶等部件承受的应力超出本身的承受能力，损坏设备，甚至发生危险事故。除此之外，在制药与生物工程等领域，一些搅拌介质如纤维、蛋白质等高分子有机物本身适合较稳定的环境，并且对剪切敏感。若在搅拌此类物料时，转速过大，会破坏物质的分子结构，影响最终产物的质量，降低混合效率。
高粘度流体不仅包括粘度较高的牛顿流体，也包括具有假塑性质的微生物多糖，对剪切敏感的纤维、蛋白质、内含催化剂颗粒的浆状流体等性质复杂的流体。润滑脂具有高粘度、低雷诺数的特点，呈剪切稀化的流变特性，是一种典型的高粘度非牛顿流体。其在搅拌过程中基本处于层流或过渡流状态。以润滑脂生产为例，在其加工处理过程中需要加入添加剂，通常需要进行搅拌混合均匀，同时保证分散质量，传统的搅拌方法是以单桨进行自转搅拌，这种方法对于以润滑脂为典型的高粘度非牛顿流体，容易出现转速低，循环能力不强，易出现死区等问题，因此传统的单桨搅拌已经满足不了其要求。

进一步的，所述第一传动轴303由第一轴段303a、第二轴段303b、第三轴段303c以及第四轴段303d组成，便于零件加工、装配。
优选的，所述显示屏502通过螺栓联接内嵌于所述电气柜503的正前方，用来显示所述 电机202的转向、转速以及所述顶板103抬升的高度。
较佳的，所述混合轮系组件305包括与所述顶板103连接的轮系箱体305f、与所述轮系箱体305f连接的第三推力圆柱滚子轴承305e、与所述第三推力圆柱滚子轴承305e连接的齿圈下过渡件305d、与所述齿圈下过渡件305d螺栓连接的齿圈305c、与所述齿圈305c螺栓连接的齿圈上过渡件305b、与所述齿圈上过渡件305b连接的第一深沟球轴承305a、与所述第一传动轴303连接的第六齿轮305j、与所述第二传动轴304连接的第七齿轮305i、与所述齿圈305c啮合的第八齿轮305h、与所述齿圈305c啮合的第九齿轮305k、与所述齿圈305c啮合的第十齿轮305m，可以实现所述混合轮系组件305中各个齿轮的转动。
适宜的，所述支撑旋转组件306包括与所述执行单元400连接的组件外框架306c、与所述组件外框架306c螺栓连接的第五轴承座306a、与所述第五轴承座306a连接的第六轴承座306d，所述第一传动轴303底端与所述第五轴承座306a和第六轴承座306d之间分别通过第二深沟球轴承306b和第四推力圆柱滚子轴承306e连接，能够达到支撑所述执行单元400作用的同时，不影响所述执行单元400的正常运转。
进一步的，所述滑块302d设置多个，根据所述导轨302c的两倍数量来确定所述滑块302d的数量，在本实施例中，所述导轨302c设置两个，相对应的，所述滑块302d即设置四个。
如图6所示，所述外部框式桨401包括桨上支架401a、挡板401b和桨下支架401c，所述外部框式桨401与所述内部转子402通过轴承连接。
综上所述，使用前，通过控制所述液压缸501抬升所述顶板103到合适高度，将物料装入所述搅拌釜102后，控制所述液压缸501下降至初始高度，顺时针转动所述第一齿轮302a驱使与其啮合的所述齿条302b右移，从而带动所述驱动单元200整体右移至所述第二限位块M2处，所述第三齿轮301b恰好与所述齿轮卡槽301e卡死，不能旋转，此时，与所述第三齿轮301b连接的所述第一传动轴303即为静止，使用时，通过所述电气柜503控制所述电机202启动，所述输出轴203带动所述第四齿轮301g转动，所述第五齿轮301f经啮合带动所述第二传动轴304转动，所述第七齿轮305i随着所述第二传动轴304转动，与所述第七齿轮305i啮合的所述齿圈305c随之转动，由于所述第六齿轮305j随着所述第一传动轴303的静止而静止，与所述齿圈305c啮合的所述第八齿轮305h、所述第九齿轮305k、所述第十齿轮305m在自转的同时会产生绕所述第六齿轮305j的公转，与所述第八齿轮305h、所述第九齿轮305k、所述第十齿轮305m连接的三个所述内部转子402也随之产生自转与公转，与所述内部转子402连接的所述外部框式桨401也会产生自转。此时，所述外部框式桨401与所述内部转子402将产生差速转动，加之所述内部转子402自转-公转同向转动，对所述搅拌釜 102中物料产生明显的轴向流，该流型会形成流域内的循环流且流量大，有利于中高粘性流体的混合搅拌。
实施例2
参照图10～图12，为本发明的第二个实施例，基于第一个实施例的基础之上，所述内部转子402包括叶片402a和转轴402b。
优选的，所述齿圈305c的齿宽比所述第七齿轮305i的齿宽大，保证其在满足齿轮啮合强度要求的同时与下层行星轮系不产生干涉。
较佳的，所述第八齿轮305h、第九齿轮305k、第十齿轮305m的齿宽均不宜过大，且均应选取相同参数，以保证所述装置运转平稳。
适宜的，所述叶片402a应设置多个，多个所述叶片402a螺旋均匀分布在所述转轴402b上。
进一步的，所述叶片402a的长度和宽度均应控制合理的尺寸，避免过长的叶片产生过大的扭矩，徒增功耗，违背当下绿色低碳的工业趋势。
较理想的，所述叶片402a与所述转轴402b的轴向剖面应有一定的角度，以提高所述搅拌釜102中物料的单位搅拌循环量与有效搅拌体积。
具体的，物料装入后，逆时针转动所述第一齿轮302a驱使与其啮合的所述齿条302b左移，从而带动所述驱动单元200整体左移至所述第一限位块M1处，所述第五齿轮301f恰好与所述齿轮卡槽301e卡死，不能旋转，此时，与所述第五齿轮连接的所述第二传动轴304即为静止，与所述第二传动轴304连接的第七齿轮305i也随之静止，使用时，通过所述电气柜503控制所述电机202启动，所述输出轴203带动所述第二齿轮301c转动，所述第三齿轮301b经啮合带动所述第一传动轴303转动，所述第六齿轮305j随着所述第一传动轴303转动，与所述第六齿轮305j啮合的所述第八齿轮305h、所述第九齿轮305k、所述第十齿轮305m随之转动，由于所述齿圈305c随着第七齿轮305i的静止而静止，与所述齿圈305c啮合的所述第八齿轮305h、所述第九齿轮305k、所述第十齿轮305m在自转的同时会产生绕所述第六齿轮305j的公转，与所述第八齿轮305h、所述第九齿轮305k、所述第十齿轮305m连接的所述内部转子402也随之产生自转与公转，与所述内部转子402连接的所述外部框式桨401也会产生自转。此时，所述外部框式桨401与所述内部转子402将产生差速转动，加之所述内部转子402自转-公转反向转动，对所述搅拌釜102中流体产生明显的径向流，该流型对流体的剪切作用较强，有利于低粘性流体的混合搅拌。
需要说明的是，其余结构均与实施例1相同，此处不做赘述。
实施例3
参照图13，为本发明的第三个实施例，基于第二个实施例的基础之上，所述驱动单元200调整为双电机驱动。
优选的，所述第一传动轴303由左侧电机输出轴上的第十一齿轮307与所述第三齿轮301b啮合以控制转动。
较佳的，所述第二传动轴304由右侧电机输出轴上的第十二齿轮308与所述第五齿轮301f啮合以控制转动。
具体的，左侧电机工作且右侧电机关机时，可实现所述内部转子402自转-公转反向转动；左侧电机关机且右侧电机工作时，可实现所述内部转子402自转-公转同向转动。
需要说明的是，其余结构均与实施例2相同，此处不做赘述。
实施例4
所述实例中，搅拌物料1(图14中白色透明部分)的密度为1000kg/m 3，动力粘度为10P a·s，搅拌物料2(图14中黑色/灰色部分)的密度为1000kg/m 3，动力粘度为10Pa·s，搅拌物料2质量占整体搅拌物料的10％，所述外部框式桨401的转速为10rpm，所述内部转子402的公转速度为10rpm，所述内部转子402的自转速度为30rpm，且所述内部转子402的公转方向与自转方向相同。通过基于粒子算法求解器的仿真软件Particleworks进行数值模拟，所述实例仿真效果如图14所示。
由图14可以看出，通过所述粘性流体混合搅拌的机械装置的作用，搅拌物料1与搅拌物料2已充分且均匀的混合，具有较高的混合质量。
应说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。
