Description

高效管道絮凝混合器及加药搅拌装置 技术领域
本发明涉及一种固液分离设备，特别涉及一种固液分离设备前端的管道絮凝混合器。
背景技术
在固液分离设备的前端，为了保证泥水的充分分离，都会在脱水机的前端增加一个絮凝混合槽或通过一些管道混合器。
絮凝混合槽在槽底污泥和絮凝剂相遇后，在搅拌器的搅拌下，让污泥与絮凝剂混合并逐渐形成絮团。但是这种絮凝混合槽具有如下缺点：
1.由于絮凝混合槽的槽体本身的结构，难免在搅拌器搅拌的时候，会导致盲区死角的搅拌的力度不够或不均匀，导致絮凝效果不理想不稳定。
2.搅拌器的搅拌速度不会太快，导致污泥和药剂混合的不够均匀，而且聚集的能量不够，导致许多药剂没有被最有效的利用。增加了药剂的使用量，以及絮凝的效果也不够理想。
3.因为搅拌桨叶偏大偏长，容易导致叶片的变形折断，导致运行起来不稳定。
管道混合器会让污泥和絮凝剂尽可能地在管道上完成絮凝。现有常见的管道混合器输送污泥的钢管是一个圆管结构，从圆管侧壁开设通孔，垂直插入搅拌器进行搅拌，由于搅拌器的搅拌轴与圆管的中心轴相互垂直，搅拌器的搅拌叶就很难与圆弧形的管壁贴合，盲区死角不可避免，该盲区死角的搅拌的力度不够或不均匀，导致絮凝效果不理想不稳定。
发明内容
本发明要解决的技术问题之一，在于提供一种高效管道絮凝混合器，通过单独设置圆管状的搅拌管，使搅拌叶恰好容纳在搅拌管内，不会出现盲区死角，使搅拌更加充分。
本发明的高效管道絮凝混合器是这样实现的：一种高效管道絮凝混合器，包括进料管、搅拌管、出料管和搅拌器，所述进料管、搅拌管、出料管并行设置且依次连通；所述搅拌管为圆管且两端为盲端，所述搅拌器包括驱动电机、搅拌叶和中心轴，所述中心轴一端连接所述驱动电机，另一端连接搅拌叶；所述搅拌叶的轴向长度满足搅拌叶能恰好容纳在搅拌管内。
进一步的，所述进料管、出料管的侧壁开设有一缺口，所述搅拌管的侧壁开设有两缺口，所述搅拌管的两缺口分别与所述进料管、出料管的缺口直接对接以连通。
进一步的，所述缺口均为轴向长条形，且缺口的长度等于搅拌管的长度。
进一步的，所述进料管与进料口相反的一端为盲端，所述出料管与出料口相反的一端为盲端，且所述进料管的盲端，所述出料管的盲端与所述搅拌管的一盲端平齐。
进一步的，所述驱动电机直接连接在搅拌管的一盲端外。
进一步的，所述搅拌管的一端还设有一加药室，所述驱动电机连接在加药室的外端，所述搅拌器的中心轴为中空轴，中心轴的上段位于该加药室内，下段则位于所述搅拌管内并连接搅拌叶，所述加药室的侧壁上设有一连通加药室的加药孔，所述中心轴的上段设有轴心药剂入口，下段设有药剂喷射口。
进一步的，所述药剂喷射口为轴向长条状。
进一步的，所述加药室的上端设有用于穿设所述中心轴的轴孔，且轴孔处设有机械密封装置。
进一步的，所述进料管的侧壁上直接开设有一加药孔。
本发明要解决的技术问题之二，在于提供一种加药搅拌装置，药剂经加药室可引入中空的中心轴内，再由中心轴中喷出至搅拌室，这种加药方式可使搅拌更加充分。
本发明的加药搅拌装置是这样实现的：一种加药搅拌装置，包括驱动电机、搅拌叶、中心轴以及加药室；所述驱动电机与加药室固定连接，所述中心轴一端连接所述驱动电机，另一端穿过所述加药室后连接搅拌叶；所述中心轴为中空轴，加药室的侧壁上设有连通加药室的加药孔，所述中心轴处于 加药室内的那段设有轴心药剂入口，连接搅拌叶的那段则设有药剂喷射口。
本发明具有如下优点：
1、通过单独设置圆管状的搅拌管，并限制搅拌叶的搅拌范围和搅拌管的内部空间，这样，搅拌叶的搅拌范围与搅拌管内表面基本吻合，使搅拌在一个相对封闭而且狭小的腔体内进行，从而不会出现盲区死角，让搅拌的更加稳定均匀；
2、搅拌管与进料管、出料管并行布置且直接通过缺口对接连通，物料与絮凝剂经过高速搅拌混合后，又经过出料管的侧壁的阻挡和缓冲絮凝效果也会更加稳定；
3、因为搅拌管设置为两端盲管，驱动电机可以直接安装在搅拌管的一端上，所以不需要更长的中心轴，有利于在告诉旋转的时候，增加稳定性，同时降低对密封性的要求。减少对搅拌叶片的损害；
4、加药方式可以有两种选择，一种是通过进料管直接加入絮凝剂，也可以通过设置加药室，将絮凝剂引入中空的中心轴，再从中心轴喷射加药，使搅拌更容易均匀。
附图说明
下面参照附图结合实施例对本发明作进一步的说明。
图1为本发明管道絮凝混合器一较佳实施例的结构示意图。
图2为本发明管道絮凝混合器另一较佳实施例的结构示意图。
图2A为图2的沿A-A处的剖视结构示意图。
图3为本发明管道絮凝混合器中进料管、搅拌管、出料管的整体结构示意图。
图4为图3的分解结构示意图。
图5为本发明加药搅拌装置的结构示意图。
具体实施方式
如图1至图4所示，本发明的高效管道絮凝混合器，包括进料管1、搅拌管2、出料管3和搅拌器4，所述进料管1、搅拌管2、出料管3并行设置 且依次连通；
所述搅拌管2为圆管，且两端为盲端，可使搅拌在一个相对封闭而且狭小的腔体内进行，以使搅拌没有盲区。所述进料管1与进料口相反的一端为盲端，所述出料管2与出料口相反的一端为盲端。且所述进料管1的盲端，所述出料管3的盲端与所述搅拌管2的一盲端平齐，比如可以通过同一块封板5进行密封。
如图3和图4所示，所述进料管1、出料管3的侧壁开设有一缺口11和31，所述搅拌管2的侧壁开设有两缺口21，所述搅拌管2的两缺口21分别与所述进料管缺口11、出料管的缺口31直接对接以连通。通过缺口直接对接可流程短、流速快，搅拌管2出来的液体可直接冲击到出料管3的侧壁，相当于再次搅拌，从而进一步提高搅拌效果。
所述进料管1的缺口11、搅拌管2的缺口21和出料管3的缺口31均为轴向长条形，且该些缺口的长度等于搅拌管2的长度，这样可使缺口较大，进一步提高流速、缩短流程，从而进一步提高搅拌效率。
所述搅拌器4包括驱动电机41、搅拌叶42和中心轴43，所述中心轴43一端连接所述驱动电机41，另一端连接搅拌叶42；搅拌叶42的轴向长度略小于搅拌管2的长度，所述搅拌叶42的轴向长度满足搅拌叶42能恰好容纳在搅拌管2内。这样搅拌叶42在转动的时候，与搅拌管2的前后两个盲端的内表面吻合，不会出现搅拌盲区死角。所述驱动电机41为正反双向调速电机，且转速由一变频器(未图示)来控制，如此可根据具体情况进行调速搅拌方向和搅拌速度。
至于加药方式，本发明可以有两种方式进行加药：
第一种，如图1、图3和图4所示，为进料管加药方式，所述进料管上设有用于引入絮凝剂的加药孔6。这样，所述驱动电机可以直接设置在搅拌管的一盲端。
第二种，如图2和图2A所示，所述搅拌管2的一端还设有一加药室7，所述驱动电机41连接在加药室7的外端，所述搅拌器2的中心轴43为中空轴，中心轴43的上段位于该加药室内7，下段则位于所述搅拌管2内并连 接搅拌叶42，加药室7的侧壁上设有连通加药室7的加药孔6，所述中心轴43的上段设有轴心药剂入口431，下段设有药剂喷射口432。当药剂从加药孔6进入加药室7后，通过轴心药剂入口431进入中心轴43，然后从药剂喷射口432处喷射而出，所述药剂喷射口432为轴向长条状，其长度可以接近搅拌器2的长度，使絮凝剂的喷射更加均匀。
所述加药室7的上端设有用于穿设所述中心轴43的轴孔23，且轴孔处设有机械密封装置72，以防止絮凝剂从轴孔流出。
如图5所示，本发明的加药搅拌装置，包括驱动电机101、搅拌叶102、中心轴103以及加药室104；所述驱动电机101与加药室104固定连接，所述中心轴103一端连接所述驱动电机101，另一端穿过所述加药室104后连接搅拌叶102；所述中心轴103为中空轴，加药室104的侧壁上设有连通加药室104的加药孔105，所述中心轴103处于加药室104内的那段设有轴心药剂入口106，连接搅拌叶102的那段则设有药剂喷射口107。
使用时，将搅拌叶102伸入搅拌室内，从加药孔105引入药剂至加药室104内，再经轴心药剂入口106进入中空的中心轴103，最后由药剂喷射口107喷射至搅拌室，一边喷射一边搅拌，使搅拌更加均匀和充分。
