Description

一种自转速度可调的行星式球磨机
技术领域
本发明属于粉末生产设备领域，尤其涉及到一种自转速度可调的行星式球磨机。背景技术
行星式球磨机是针对粉碎、研磨、分散金属、非金属、有机、中草药等粉体进行设计，特别适合实验室研究使用，其工作原理是利用磨料与试料在研磨罐内高速翻滚，对物料产生强力剪切、冲击、碾压达到粉碎、研磨、分散、乳化物料的目的。行星式球磨机一般在同一转盘上装有四个球磨罐，当转盘转动时，球磨罐在绕转盘轴公转的同时又围绕自身轴心自转，罐中磨球在高速运动中相互碰撞，研磨和混合样品。行星式球磨机可采用干、湿两种方法研磨和混合不同粒度、材料各异的粉末，研磨粉末最小粒度可至0.1微米，能很好的实现各种工艺参数要求，同时由于其小批量、低功耗、低价位的优点，是学校、研究单位、公司是进行粉碎工艺、新材料、涂料研究的首选设备。
球磨是机械合金化工艺实现的主要方法，而温度是球磨过程中重要的影响因素，磨球的冲击动能和物料的反应发热将引起温度升高。较低的温度更有利于物料和微观组织的细化，有利于球磨物料亚稳态结构的稳定。
发明内容
针对上述问题，本发明提出一种自转速度可调的行星式球磨机，其设备简单、连接可靠、可通过调节球磨罐自转速度实现对球磨过程的控制。
本发明的设备由空气压缩机（附有可充电式电源）、压缩空气导管、球磨罐、喷射管、叶片、电机、行星传动机构、公转轴、公转筒、球磨罐自转测速计组成。其特征在于：空气压缩机、球磨罐自转测速计与公转筒之间采用橡胶垫等减震方式，空气压缩机、球磨罐自转测速计（采用非接触式传感器）采用机械方式固定于公转筒，压缩空气导管与公转轴的连接就转换为静态连接，空气压缩机的电源采用可充电的铅酸或锂电池等；公转轴为一端封闭的盲管，压缩空气出口与公转轴孔未封闭端相通，公转轴盲孔端在盲孔底部开有周向孔，喷射管孔与公转轴盲孔的周向孔相通，从而空气压缩机→公转轴→喷射管组成为压缩空气的通道；叶片形状采用圆弧、旋轮线或渐开线形状等，叶片固定于球磨罐的外壁，喷射管延长线贯穿叶片自转形成的圆柱面，从而压缩空气喷射于叶片，推动球磨罐的自转；行星传动机构由减速与传动机构构成，可采用齿轮或皮带轮等形式。
本发明的工艺原理为：电动机通过行星传动机构带动公转轴旋转，公转轴与公转筒之间采用刚性连接，从而带动公转筒公转，磨球在研磨罐内高速翻滚推动球磨罐自转。空气压缩机产生高压气体经压缩空气导管→公转轴→喷射管作用于固定在球磨罐的叶片，从而使球磨罐的自转速度增大。通过调整压缩空气的流量和压力，从而实现球磨罐自转速度的控制。
本发明具有以下优点：
1.由于采用在球磨罐外壁上安装有叶片、叶片在压缩空气的推动下，可增大球磨罐的自转速度，提高球磨的效率；
2.通过调整喷射管的安装位置和角度，压缩空气在推动叶片同时可作用于球磨罐外壁，以增强球磨罐外壁的散热，降低球磨罐内物料的温度；
3.可通过喷射管的设计变更，让喷射压缩空气更换为水雾或其它气体等，以增强球磨罐的冷却效果；
4.通过球磨罐自转测速计和压缩空气流量、压力的配合，可实现大范围球磨罐自转速度的可调。
