Description

一体式耐磨淤泥渣土处理装置
技术领域
　　本发明涉及一种用于处理城市建设过程中产生的淤泥渣土的处理装置，尤其是在城市建设中挖出的泥土，如地铁施工、房屋建筑挖地基等产生的渣土的一体式耐磨淤泥渣土处理装置。
技术背景
　　地铁建设和高层楼房建筑是一个城市飞速发展的标志。在地铁建设和高层楼房建筑中，必然会产生大量的被挖掘出来的泥土。现在处理这类泥土的方法只有一种方式，就是在城市的周边地带，适合堆土的地方建立若干泥土受纳场。把城市建设过程中产生的泥土直接通过泥土车送到这些受纳场填埋，这种处理方法其实质上就是把需要建设的地方挖掘出来的泥土转运到了暂时不需要进行城市建设的地方。可是，在城市周边适合于用来作为受纳场地方，也越来越少，不得已，只能将现有受纳场超负荷运行，形成人为的山体，这种人为的山体土质相对疏松，一旦受到地理环境变化和天气因素的影响，如地震或长时间下雨，很容易引起人为山体滑坡，造成不可估量的人为损失。如今年夏天，南方某市的这种受纳场的人为山体滑坡，就几乎将山体周边的几个工业区全部毁埋，造成了巨大的人员伤亡和财产损失。
　　中国专利文献CN202087272U公开了一种回转式滚筒搅拌机,包括输送装置,其一端设有污泥入口,另一端设有污泥出口,输送装置具有输送通道,输送通道内设有至少一个无轴螺旋叶片,无轴螺旋叶片自污泥入口延伸至污泥出口,无轴螺旋叶片靠近污泥入口的一端连接有动力源;搅拌滚筒,其具有搅拌腔,搅拌滚筒的一端设有入料口,另一端设有出料口,入料口与污泥出口相连,搅拌滚筒的外环壁上套设有大传动齿轮,搅拌腔的内侧壁上沿圆周方向固定连接有多片扬料板;传动装置,其与大传动齿轮相连。该回转式滚筒搅拌机可以充分搅拌污泥与固化剂的混合物,使污泥的固化更加彻底均匀,其可连续不间断的进料搅拌污泥,并使搅拌固化后的污泥排出,实现污泥处理的流水生产化。这种回转式滚筒搅拌机处理量小，只适合于工地清除淤泥，而不适合于在城市建设中挖出的泥土，如地铁施工、房屋建筑挖地基等产生的渣土的处理。
　　因此，如何快速的工业化处理由城市建设所产生的泥土，使其变废为宝是摆在人们面前的一个亟待解决的问题。
发明内容
　　为了解决现有技术的不足，本发明向社会提供一种可以将城市建设过程中产生的泥土，进行快速化工业处理，使其变为建筑用料和工业泥土的一体式耐磨淤泥渣土处理装置。
　　本发明的技术方案是：提供一种一体式耐磨淤泥渣土处理装置，为滚筒形，主要适合于用来处理城市建设中挖掘出来的泥砂土，至少包括磨料部分和泥砂分离部分；在所述磨料部分的滚筒内壁上的磨料件将进入磨料部分内的被处理泥砂初步破碎，并送入到泥砂分离部分，在泥砂分离部分的外侧设有高压稀释水喷嘴，将进入到所述物料分离部分的泥砂稀释成稀泥砂，所述泥砂分离部分允许粒径小于大料预定粒径的稀泥砂混合物通过；而粒径大于等于大料预定粒径的大料混合物则被从排料口排出；所述磨料件是由片状材料制成规则几何形状的磨料件。
　　作为对本发明的改进，所述规则几何形状可以是多边形，如三角形、五边形至八边形等。
　　作为对本发明的改进，所述磨料件是用高碳铁合金制造，由重量百分比的钛13％～16％、碳4-6％、硅2-3％、铅1-3％、碳化钨5-8%、硼2－5%、铬2－5%，余量为铁组成。
　　作为对本发明的改进，所述滚筒式泥砂分离装置的直径在1米-5米之间选择，长度在5－20米之间选择。
　　作为对本发明的改进，所述大料预定粒径在20毫米-50毫米之间选择。
　　作为对本发明的改进，还包括输料段，以延长待处理泥土进入磨料部分的时间；在所述输料段的滚筒内壁上设有第一曲形导料板，若干相互平行的轴向设置的第一曲形导料板构成若干第一曲形导料槽，待处理泥砂沿第一曲形导料槽被送入磨料部分。
　　作为对本发明的改进，在所述磨料部分的滚筒内壁上设有第二曲形导料板，若干相互平行的轴向设置的第二曲形导料板构成若干第二曲形导料槽，在所述第二曲形导料槽内设有若干磨料件和用于随滚筒旋转而提升待处理泥砂的径向设置的周向档板，待处理泥砂在磨料部分内一方面被进行磨料件不断击碎，同时还在周向档板作用下，不断被在滚筒提升后再下落，达到进一步击碎；被击碎的泥砂沿第二曲形导料槽前行，进入泥砂分离部分。
　　本发明由于采用了滚筒式泥砂分离装置将被处理泥砂处理成稀泥砂和大料混合物，这样，从工地用泥土车拉来的废泥土可直接倒入分离装置内，被迅速处理成稀泥砂和大料混合物，不会造成堆积；另外，被处理出来的泥土，根据泥土成份的不同可以制成陶制品或瓷制品，真正做到了所有废物被全部利用，实现了变废为宝，是一项绿绝的可持续发展的项目。采用本发明的系统可实现冲洗泥浆中98%以上的有用料回收利用,废水净化后可以实现90%以上再利用。

具体实施方式
　　请参见图1和图2，图1和图2揭示的是一种一体滚筒式泥砂分离装置1，安装时，将所述滚筒式泥砂分离装置1斜着安装，其入料口132高于排料口122，以利等处理泥砂在重力的作用下下行，在滚筒外壁圆周上设圆形齿轮14，在所述齿轮14的两侧设有圆形导轨15，电机16带动驱动齿轮161通过齿轮14带动滚筒式泥砂分离装置1转动，在所述齿轮14的两侧的滚筒上设有圆形导轨15，所述圆形导轨15与分布在所述滚筒两侧的导轮17配合，起到支撑与导动的作用；所述滚筒式泥砂分离装置1至少包括磨料部分11和泥砂分离部分12；在所述磨料部分11的滚筒内壁上的磨料件111将进入磨料部分11内的被处理泥砂初步破碎，并送入到泥砂分离部分12，在泥砂分离部分12的外侧设有高压稀释水喷嘴121，将进入到所述物料分离部分12的泥砂稀释成稀泥砂，所述泥砂分离部分允许粒径小于大料预定粒径的稀泥砂混合物通过圆孔123；而粒径大于等于大料预定粒径的大料混合物则被从排料口122排出；本实施例中，所述大料预定粒径在20毫米-50毫米之间选择，具体实施起来，可以是泥砂分离部分的滚筒上设置若干直径为20毫米-50毫米中的圆孔123，被初步破碎后的泥砂，当其直径小于或等于20毫米-50毫米时，可以从圆孔123中下漏；而直径大于20毫米-50毫米的大料，包括金属类、竹木类、塑料类，以及大颗粒石料和泥料等，都从排料口122排出，从排料口122排出的大料，再经后述的大料处理工序进行处理。
当滚筒式泥砂分离装置的直径在3米以上时，10-20吨的泥土车可以直接将待处理泥土倒入滚筒式泥砂分离装置内，这种情况下，最好在滚筒式泥砂分离装置的最前段设置一个输料段13，以延长待处理泥土进入磨料部分11的时间，并在此输料段13加入适当水分将待处理泥土进行初步稀释；在所述输料段13的滚筒内壁上设有第一曲形导料板1311，若干相互平行的轴向设置的第一曲形导料板1311构成若干第一曲形导料槽131，待处理泥砂沿第一曲形导料槽131被送入磨料部分11。
　　在所述磨料部分11的滚筒内壁上设有第二曲形导料板112，若干相互平行的轴向设置的第二曲形导料板112构成若干第二曲形导料槽113，在所述第二曲形导料槽113内设有若干磨料件111和用于随滚筒旋转而提升待处理泥砂的径向设置的周向档板114，待处理泥砂在磨料部分11内一方面被进行磨料件111不断击碎，同时还在周向档板114作用下，不断被在滚筒提升后再下落，达到进一步击碎；被击碎的泥砂沿第二曲形导料槽113前行，进入泥砂分离部分12。
　　优选的，所述磨料件111是由片状材料制成规则几何形状的磨料件。
　　所述规则几何形状可以是多边形，如三角形、五边形至八边形等。
　　为了提高磨料件111的耐磨性，所述磨料件111可用下述高碳铁合金制造，其由重量百分比的钛13％～16％、碳4-6％、硅2-3％、铅1-3％、碳化钨5-8%、铜0.1-0.3%、硼2－5%、铬2－5%，余量为铁。
　　实施例1
　　所述磨料件111可用下述高碳铁合金制造，其由重量百分比的钛13％、碳4％、硅2％、铅1％、碳化钨5％、铜0.1%、硼2％和铬2％，余量为铁。
　　实施例2
　　所述磨料件111可用下述高碳铁合金制造，其由重量百分比的钛14％、碳5％、硅3％、铅2％、碳化钨6%、铜0.2%、硼4%、铬4%，余量为铁。
　　实施例3
　　所述磨料件111可用下述高碳铁合金制造，其由重量百分比的钛16％、碳6％、硅3％、铅3％、碳化钨8%、铜0.3%、硼5%、铬5%，余量为铁。
　　 上述合金的不同之处在，一般人认为铜对于铁合金来说是一处有害元素，不能使用，而本发明将铜元素与碳化钨一起加入到铁钛合金里时，大大地提高了铁钛合的耐磨性能。
　　本发明的磨料件与市面上购买的铁钛合的耐磨性对比测试方法及结果：
　　测试方法，使用器件，ML－10型磨料磨损试验机，200#刚玉砂纸，万分之一精度天平。试样转速为180转/分钟，法向载荷力为750N，时间为4小时。
　　试验结果：

　样品 磨损量（mg） 对照样品 6.2 实施例1 3.6 实施例2 3.7 实施例3 3.5 从上表可以看出，本发明的磨料件与市面上购买的铁钛合相比，具有耐磨性能好的优点。
　　优选的，所述滚筒式泥砂分离装置的直径在1米-5米之间选择，长度在5米－20米之间选择。
