Description

一种使用混合式搅拌臂的搅拌器
技术领域
本发明涉及一种沥青搅拌站,尤其涉及一种使用混合式搅拌臂的搅拌器。
背景技术
沥青搅拌站,也可叫做沥青混凝土搅拌站,该设备可生产沥青混合料、改性沥青混合料、彩色沥青混合料,完全满足修筑高速公路、等级公路、市政道路、机场、港口等的需要。
搅拌器作为沥青搅拌站的核心部件,一直以来用户关注度很高,而对于传统的对置叶片的搅拌臂布置形式,由于搅拌臂及叶片数量多,总面积大,导致搅拌能耗过高,选用电机功率偏大,影响了搅拌站的整体性能;另外由于混合料对搅拌器的连续冲击,造成搅拌框架乃至整个楼体的振动加大,损害楼体寿命。
发明内容
针对上述现有技术存在的问题,本发明提供一种使用混合式搅拌臂的搅拌器,能够在保证搅拌均匀性的前提下降低搅拌能耗,并且大幅减小混合料对搅拌器乃至整个楼体的冲击,从而减轻主楼因搅拌器工作引起的振动。
为了实现上述目的,本发明采用的技术方案是:一种使用混合式搅拌臂的搅拌器,包括搅拌器壳体、放料门、搅拌装置和同步齿轮,所述搅拌器壳体内搅拌臂设置搅拌臂,搅拌装置连接拌器壳体外同步齿轮,搅拌器壳体底部设置放料门;所述搅拌装置包括第一搅拌轴和第二搅拌轴、轴承、单置叶片搅拌臂、对置叶片搅拌臂和对置返回叶片搅拌臂;所述第一、二搅拌轴通过轴承安装在搅拌器壳体上;第一、二搅拌轴混合间隔排列单置多组叶片搅拌臂、多组对置叶片搅拌臂,和一组对置返回叶片搅拌臂,相邻两搅拌轴上的对置叶片搅拌臂交错排列、相邻两搅拌轴上的对置返回叶片搅拌臂交错排列,在两根搅拌轴的搅拌叶片作用下混合料在搅拌器内形成围流运动。
本发明进一步的,所述拌器壳体内壁设置耐磨衬板。
本发明进一步的,所述轴承上安装轴端密封。
本发明进一步的,所述第一、二搅拌轴混合间隔排列单置三组叶片搅拌臂、三组对置叶片搅拌臂。
与现有技术相比,本使用新型的有益效果是:第一,单置叶片搅拌臂与对置叶片搅拌臂的混合排列,有助于在保证搅拌均匀性的前提下最大限度降低搅拌叶片总面积,从而降低搅拌能耗;第二,这种混合式搅拌臂可以使搅拌叶片对混合料的推力变为非连续性的,有效降低混合料对搅拌器轴向的冲击力,提升搅拌器乃至整个楼体的稳定性。
附图说明
图1为本发明的结构示意图;
图2为本发明搅拌臂俯视示意图;
图3为本发明搅拌臂主视示意图。
图中:1、搅拌器壳体,2、耐磨衬板,3、放料门,4、搅拌装置,5、同步齿轮,6、第一搅拌轴,7、轴承,8、单置叶片搅拌臂,9、对置叶片搅拌臂,10、对置返回叶片搅拌臂,11、轴端密封,12、第二搅拌轴。
具体实施方式
下面将结合附图对本发明作进一步说明。
如图1所示,本发明一种使用混合式搅拌臂的搅拌器,包括搅拌器壳体1、放料门3、搅拌装置4和同步齿轮5搅拌器壳体1内搅拌装置4设置搅拌装置4,搅拌装置4连接拌器壳体1外同步齿轮5,搅拌器壳体1底部设置放料门3;搅拌装置4包括第一搅拌轴6和第二搅拌轴12、轴承7、单置叶片搅拌臂8、对置叶片搅拌臂9和对置返回叶片搅拌臂10;第一、二搅拌轴6、12通过轴承7安装在搅拌器壳体1上;第一、二搅拌轴6、12混合间隔排列单置多组叶片搅拌臂8、多组对置叶片搅拌臂9,和一组对置返回叶片搅拌臂10,相邻两搅拌轴上的对置叶片搅拌臂9交错排列、相邻两搅拌轴上的对置返回叶片搅拌臂10交错排列,在两根搅拌轴的搅拌叶片作用下混合料在搅拌器内形成围流运动。
使工作时,同步齿轮5驱动两个搅拌轴同时转动,由于单置叶片搅拌臂8与对置叶片搅拌臂9的混合排列,相邻两搅拌轴上的对置叶片搅拌臂9交错排列,有助于在保证搅拌均匀性的前提下最大限度降低搅拌叶片总面积,从而降低搅拌能耗;设置有一组对置返回叶片搅拌臂10,在搅拌时反向旋转,这种混合式搅拌臂可以使搅拌叶片对混合料的推力变为非连续性的,有效降低混合料对搅拌器轴向的冲击力,提升搅拌器乃至整体的稳定性。
在上述结构基础上,本发明在拌器壳体1内壁设置耐磨衬板2。为工件的磨损提供了重要的耐磨保护措施,提高了设备、工件的使用寿命。在轴承7上安装轴端密封11,防止润滑油等介质外漏。
本发明搅拌臂的数量可根据实际需要进行调整,本发明优选第一、二搅拌轴6、12混合间隔排列单置三组叶片搅拌臂8、三组对置叶片搅拌臂9。
当然,上述实施例仅是本发明的优选方案,具体并不局限于此,在此基础上可根据实际需要作出具有针对性的调整,从而得到不同的实施方式。由于可能实现的方式较多,这里就不再一一举例说明。
