Description

一种物料增压装置 技术领域
本发明涉及水泥建材领域，尤其涉及一种物料增压装置。
背景技术
目前在水泥建材等行业中，辊压机由于其高效的粉磨及粉碎效率，广泛地用于原料粉磨，水泥粉磨等环节。由于辊压机原理上是两个辊对物料进行对挤的特点，其运行时为了保障物料稳定顺利地进入辊缝，保持辊压机的持续稳定运行，进入辊压机的物料需保持一定的料压。目前工艺上的普遍解决办法是将辊压机的厂房建高，在其上层设置稳料仓，然后通过一根4到5米的下料管接到辊压机的下料口，通过物料本身的重力保持辊压机的料层压力。这就造成辊压机所在车间的层高偏高，不仅混凝土的支柱高度、大小需要增大，粉磨系统相应提升设备的高度也偏高。
因此，亟待研发设计出一种能解决上述问题的物料增压装置。
发明内容
本发明的目的鉴于上述缺点，从而提供一种物料增压装置。
为实现上述目的，本发明提供了一种物料增压装置，该装置包括管体，所述管体内部中空，管体内壁设有下旋的螺旋体，所述管体外壁从上至下依次设有上部法兰、中部法兰和下部法兰，所述上部法兰上固定有第一旋转件，所述管体上端口通过第一旋转件与物料仓旋转连接；所述中部法兰上固定有用以驱动管体旋转的驱动装置；所述下部法兰上固定有第二旋转件，所述管体下端口通过第二旋转件与辊压机喂料口旋转连接，所述第一旋转件与第二旋转件之间设有用于固定二者的第一固定支架，所述第一固定支架固定在所述辊压机喂料口的外壳上。
进一步地，所述螺旋体为均匀安装在内壁的多个螺旋条。

进一步地，所述驱动装置包括第一链轮、第二链轮和减速电机，所述第一链轮套在管体外壁上，并与所述中部法兰固定连接；所述第一链轮通过链条连接有第二链轮，所述第二链轮与所述减速电机相连。
更进一步地，所述第二链轮通过限距联轴器与减速电机相连。
更进一步地，所述减速电机安装在第二固定支架上，所述第二固定支架固定在所述辊压机喂料口的外壳上。
进一步地，所述第一旋转件为径向轴承，所述径向轴承的内圈与上部法兰连接，所述第二旋转件为轴向轴承，轴向轴承的下圈与下部法兰连接，所述径向轴承的外圈和轴向轴承的上圈分别与所述第一固定支架连接。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面将结合发明实施例中的附图，对发明实施例中的技术方案进行清楚、完整地描述，显然，下面所描述的实施例仅仅是发明一部分实施例，而非全部的实施例。基于发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于发明保护的范围。
如图1至2所示，本发明实施例提供的一种物料增压装置包括管体1，管体1采用耐磨材料制作，管体1内部中空，管体1内壁设有下旋的螺旋体2。管体1外壁从上至下依次设有上部法兰3、中部法兰4和下部法兰5。上部法兰3上固定有第一旋转件6，管体上端口通过第一旋转件6与物料仓7旋转连接。中部法兰4上固定有驱动装置，通过驱动装 置驱动管体1旋转。下部法兰5上固定有第二旋转件8，管体1下端口通过第二旋转件8与辊压机喂料口9旋转连接。第一旋转件6与第二旋转件8之间设有第一固定支架10，第一旋转件6与第二旋转件8均固定在第一固定支架10上，第一固定支架10固定在辊压机喂料口9的外壳上。
如图1所示，本发明实施例的第一旋转件6为径向轴承，第二旋转件8为轴向轴承，径向轴承的外圈和内圈上打有多个安装孔，轴向轴承的上圈和下圈上也打有安装孔，通过安装孔便于与其它部件的固定。径向轴承的内圈与上部法兰3通过螺栓连接，轴向轴承的下圈与下部法兰5通过连接，径向轴承的外圈和轴向轴承的上圈分别与第一固定支架10通过螺栓连接。径向轴承的结构等同于深沟球轴承，主要承受管体旋转时的径向力。轴向轴承结构等同于推力轴承，主要作用为承受管体1运转时挤压物料产生的向上的反作用力。
第一固定支架10主要用来固定径向轴承和轴向轴承，两轴承固定后相当于间接定位了管体1，使之在固定的位置进行旋转，同时第一固定支架10也是整个增压装置的骨架，整个物料增压装置通过第一固定支架10与下部的辊压机喂料口9的外壳刚性固定，同时也与上部的物料仓7通过软连接结构11连接。本发明实施例中的软连接结构11两端可分别焊接在物料仓7外壁和径向轴承外圈上，或软连接结构11两端分别采用法兰与物料仓7外壁和径向轴承外圈固定连接。其中，软连接结构可以为膨胀节、橡胶管、塑料管、硅胶布或帆布中的一种。通过软连接结构11的设置可起到吸收膨胀和减少振动的作用。
如图1和图2所示，本发明实施例的螺旋体2为单独焊接在内壁的多个螺旋条，螺旋且顶部伸出一定的长度，即螺旋体2的上端高于管体1上端口。通过在管体1内壁焊接螺旋条，可便于物料仓下料，物料在螺旋的作用下产生向下的压力，保障下部物料一定的料压。通过将螺旋体2上端接入物料仓7，且螺旋体2伸入物料仓7内一定的距离，对物料起到助流作用，管体下部接辊压机喂料口9，由于辊压机运行时从物料仓7到管体1再到辊压机辊面之间物料是充满状态，管体1旋转时螺旋体2会自动给底部的物料一个向下的压力，从而代替物料重力施加料压。管体在螺旋体2中部留有一定的空间，从而保障较大块的物料也能顺利的通过。
本发明实施例的驱动装置包括第一链轮12、第二链轮13、限距联轴器14和减速电机15，第一链轮12套在管体1外壁上，并与中部法兰2通过螺栓固定连接。第一链轮12通过链条16连接有第二链轮13，第二链轮13与限距联轴器14连接，限距联轴器14与减速电机15相连，主要起到保护设备的作用。减速电机15安装在第二固定支架17上，第二固 定支架17固定在辊压机喂料口9的外壳上。管体1内的螺旋体2旋转时，对充满其内部的物料产生向下的压力，从而保证了辊压机运转时对其喂料装置里面料压的要求。同时，在辊压机下料不畅或者其他原因导致料压过大时，传动系统受力大于限距联轴器14设定好的力矩，限距联轴器14脱开，保护传动设备及轴承等重要部件。
工作时，驱动装置驱动第一链轮12转动，从而带动管体1内壁的螺旋体2旋转，由于螺旋体2的顶部伸入了物料仓内，在螺旋体2本身螺旋的作用下，物料仓内的物料被强制引流入螺旋体并向下压出，在辊压机喂料口9内充满物料后，螺旋体2的旋转就会对物料产生压力，从而达到产生料压的效果。料压产生后，螺旋体2会受到垂直向上的反作用力，这个力被轴向轴承承受并通过螺栓传递到辊压机喂料口上。
当发生故障时，如辊压机堵料等，管体1内壁螺旋体2旋转产生的反作用力快速增大，导致驱动装置中的第二链轮13受力增大，当驱动装置的受力达到限距联轴器14的设定力矩后，减速电机15与第二链轮13脱开，管体1停止旋转，不再产生更大的压力，当其底部的物料排出一部分后，第二链轮13的受力减小，限距联轴器14重新起作用，减速电机15再次驱动第二链轮13旋转，带动管体1再次开始工作旋转。
本发明提供的物料增压装置，采用旋转增压的方式，将设置在辊压机上方的物料仓内的物料引流到辊压机并施加一定的压力，保障辊压机的料压且料压可以方便地调整。具有结构简单、制作安装方便、反应灵敏等特点，可大幅度降低物料仓与辊压机之间的高度，从而节省车间高度，可以将原高度缩减约3米左右，即辊压机车间及相关提升设备等都可相应的降低约3米，在基础建设、设备高度、设备功率、安装成本等各方面都能节省成本，是十分理想的物料增压装置。
以上所述的具体实施方式，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施方式而已，并不用于限定本发明的保护范围，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
