一种秤斗称量防干扰的搅拌设备 技术领域
本发明涉及建筑材料搅拌设备，特别涉及一种秤斗称量防干扰的搅拌设备。

随着国家基建的大力发展，对建筑材料的要求越来越多且质量要求越来越高，因此对建筑材料的搅拌设备的称量准确性的要求也越来越高。搅拌设备的搅拌主机在搅拌过程中会产生大量气体，气体在搅拌主机内堆积会对被称量的物体产生向上的托力导致称量不准确；目前采用在搅拌主机上安装两个卸料阀来解决称量不准确的问题，在称量时将与搅拌主机连通的卸料阀关闭进行称量，称量完成后重新打开卸料阀；但是关闭卸料阀会使得搅拌主机内的气体压力增大，影响物料的搅拌，甚至对搅拌设备造成损害。

具体实施方式

在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，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发明的限制。此外，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
参照图1至图5，本发明实施例的一种秤斗称量防干扰的搅拌设备，包括：搅拌主机100；称斗200，设于搅拌主机100上方，用于向搅拌主机100内供料；称斗200上设有称重传感器210用于对进入 搅拌主机100内的物料进行称重；称斗200下方设有卸料阀230；卸料阀230优选为蝶阀或者能插入其内的插板。连接件300，设于搅拌主机100与称斗200之间，称斗200内的物料经过连接件300进入搅拌主机100内；风向调节装置400，设于搅拌主机100与连接件300之间，能将进入连接件300内的气体从水平方向排出，以减少进入连接件300内的气体对称斗200计量产生的干扰。具体的，当搅拌主机100搅拌时，也是一个物料挤压排气的过程。另外若干个秤斗的物料，根据搅拌时序，并不是同时卸料，则在其他秤斗卸料时也会产生排气。常见的搅拌设备如图1所示，气体在排放的过程中部分气体会通过件连接件300排出，由于气体的流体性能，会给卸料阀230一个压力，这时如果其他秤斗在称量，就会存在一个额外的力，称量的物料会比实际增加，造成称量不准。如图2所示的搅拌设备是目前为解决图1所示的搅拌设备称量不准问题做的结构改进，通过在搅拌主机100上增加一个卸料阀230来实现。实现过程为，当秤斗在称量过程中，将最下面的一个卸料阀230关闭，阻止气流流向秤斗方向。此种方法虽然解决了秤斗计量干扰的问题，但也产生了一个新问题，就是搅拌主机100内气体无法排出，随着装载的物料数量而使主机内部压力增大，可能会对主机内部造成损害。根据图2的搅拌设备，将卸料阀230改成了风向调节装置400；相比目前的搅拌设备，风向调节装置400能在不影响进料的情况下，将搅拌主机100内产生的空气源源不断的排出，使得搅拌主机100内既不会因为压力过大对设备造成损害；同时，因为风向调节装置400是将气体从水平方向排出，因此不 会对称量产生影响，提高了称量的准确性。
在本发明的一些实施例中，风向调节装置400包括喇叭口壳体410和旋转叶轮420，喇叭口壳体410设于搅拌主机100与连接件300之间，且喇叭口朝向搅拌主机100；旋转叶轮420设于喇叭口壳体410内，旋转叶轮420旋转时能将进入连接件300内的气体从水平方向排出。具体的，根据旋转叶轮420的叶片形状，可以改变从搅拌主机100进入喇叭口壳体410的气体流向，使其从垂直方向变为水平方向排出。同时，旋转叶轮420的叶片与水平面的夹角较大，称斗200内的物料能够依靠自身重力轻易地从旋转叶轮420的叶片上滑落入搅拌主机100内，不会对物料进入搅拌主机100造成干扰。
在本发明的一些实施例中，喇叭口壳体410包括直口管411、扩口管412和竖杆413，竖杆413设于直口管411和扩口管412之间，用于将两者进行连接；旋转叶轮420设于多个竖杆413围成的圆周内，多根竖杆413间隔设置。具体的，如图4、图5所示，直口管411的下部设有朝外延伸出去的法兰接头，扩口管412的顶部同样设有向外延伸的法兰接头，多个竖杆413设于直口管411与扩口管412的两个法兰接头之间，多个竖杆413围设成一圆周，旋转叶轮420设于竖杆413围成的圆周内；两两竖杆413之间具有间隙，气体可以从间隙中水平逸出。同时，喇叭口壳体410下部为扩口管412可以更好的将气体导流到旋转叶轮420外沿；根据力学力臂原理，相同力的情况下，叶轮外沿比内沿所产生的力矩大，从而旋转叶轮420旋转的速度也会相应增大。旋转叶轮420旋转速度增大发生在称斗200在称量的过程 中，由于称斗200的物料在称量的过程中需要将卸料阀230关闭，因此没有物料从旋转叶轮420中穿过，旋转叶轮420能够较为轻易的被气流驱动加速旋转，同时旋转加速能够加快搅拌主机100内的气体逸出，保证了搅拌主机100内的气体能够源源不断的逸出，不会对搅拌主机100造成损害。旋转叶轮420为无动力结构，无须增加额外动力和卸料阀230，电控点少，使用更可靠。
在本发明的一些实施例中，直口管411设有朝搅拌主机100方向延伸的活动轴240，活动轴240与旋转叶轮420的旋转中心重合，旋转叶轮420安装于活动轴240上。具体的，如图3所示，活动轴240顶部通过支架连接于直口管411的内壁上，并竖直向下延伸；活动轴240、喇叭口壳体410的中心轴线、旋转叶轮420的旋转中心轴线三者重合，旋转叶轮420中心通过螺栓固定于活动轴240上。
可以理解的是，活动轴240顶部也可以是固定于称斗200下方的出料口220的内壁上，设置于卸料阀230下方，可实现同样的功能。此外，旋转叶轮420与活动轴240也可以通过其他方式连接，例如通过插销将旋转叶轮420固定于活动轴240。
在本发明的一些实施例中，风向调节装置400还包括布袋430，布袋430围设于喇叭口壳体410外周并将竖杆413包覆其内，布袋430两端分别与直口管411和扩口管412连接。具体的，布袋430为透气布袋430，能够供空气穿过但能阻止灰尘穿过，用于将水平排出的气体过滤排放，保证加工场地的洁净。布袋430优选为可拆卸连接于喇叭口壳体410上，便于单独对其进行更换。
在本发明的一些实施例中，搅拌主机100上连接有多个称斗200，不同称斗200中的装的物料不一致，搅拌主机100用于将各种预搅拌的物料搅拌混合。一个称斗200中的物料经过称量之后进入搅拌主机100内，存在某个称斗200中的物料单独投料进入搅拌主机100的情况，或者多个称斗200同时投料进入搅拌主机100的情况。
在本发明的一些实施例中，连接件300通过柔性材料制成，优选为柔软的布袋430。布袋430可以供气流穿过，同时能够对灰尘进行阻挡，能够保持搅拌场地的洁净，同时能减少气体进入称斗200内。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
