一种铸件的清砂处理系统 技术领域
本发明涉及一种铸件的清砂处理系统。
 背景技术
目前，铸件产品都是由铸造或者锻造的毛坯加工而成，在铸造过程中往往用砂型铸造，所以铸件产品毛坯上往往残留有砂粒需要清理。人工清砂劳动强度大，劳动条件差，效率低，粉尘污染严重，清砂效果差，还会破坏铸件产品的品质。因此，也推出了一些清砂设备对铸件进行清砂，但是，由于现有的设备在清砂过程中未采用封闭式对铸件产品进行清砂，清砂过程中飞扬的砂尘经常对外界环境造成污染，使得操作人员吸入，从而影响操作人员的健康，并且，铸件在清砂完成之后并未进行封闭处理，空气中飞扬的砂粒很容易粘附在铸件表面，影响铸件清砂效果。

所述的清砂室11采用不锈钢板制成，在不锈钢板的内侧依次设有海绵硅胶板和钢丝网。
本发明的工作原理：
1、工件被固定装置固定在工件车上，工件车从工件车平台14滑入清砂室11内的旋转平台15上，然后关闭密封门13；
2、启动增压泵220，将储水罐28中的水送至高压水枪，将高压水枪架设在水枪挡板上，对工件进行清砂，同时，启动无极调速电机113，带动旋转平台15旋转；
3、清砂时可开启照明灯19，从玻璃观察窗110观察清砂室11内部的清砂情况，当清砂室11内水雾过大时，可开启排风机18快速去除水雾；
4、清砂产生的清砂水从底部的排水孔流入集砂箱12中，大颗粒砂粒被套在清砂水排水管16上的钢丝网阻挡在集砂箱12内，从而实现对砂粒的回收利用，而清砂水则从清砂水排水管16排出，并经过排水软管29流入第一沉淀池21中；
5、清砂水可通过底部连通处从第一沉淀池21流入第二沉淀池22中，并在两个沉淀池中沉淀，第二沉淀池22通过顶部的溢流口211时内部的清砂水流入蓄水池23；
6、蓄水池23内的水通过潜水泵212送入粗过滤器24进行第一次过滤，然后依次经过第一精密过滤器25、第二精密过滤器26和超滤膜过滤器27过滤后，进入储水罐28储存，蓄水池23内可设液位控制开关，设定为高液位启动潜水泵212，低液位停泵，能够适时的将蓄水池23内的水经过潜水泵212加压后进行过滤，初始状态下，第一过滤阀门225、第二过滤阀门226、第三过滤阀门227、第一反洗阀门230、第二反洗阀门231、直连阀门233均处于关闭状态，当进行常规过滤工作时，第一过滤阀门225、第二过滤阀门226、第三过滤阀门227打开，当进行快速过滤工作时，第一过滤阀门225、直连阀门233、第三过滤阀门227打开；
7、储水罐28中的水在需要时通过清水排水管218排出，并经过增压泵220增压后通过回水管道221送至高压水枪进行清砂，从而实现水的循环利用；
8、储水罐28内设液位控制器，设定为低水位打开补水电磁阀224，向储水罐28中补水，高水位关闭补水电磁阀224，停止补水，当补水电磁阀224故障无法使用时，可通过手动补水阀门223进行补水，从而保证储水罐28内的水位。
水循环系统需要定期进行反洗，从而延长使用寿命，具体操作方法如下：
1、打开第二过滤阀门226、直连阀门233、第三过滤阀门227、第一反洗阀门230和第二反洗阀门231；
2、手动打开手动补水阀门223，持续向储水罐28中补水，使得储水罐28中的水向前流动，依次经过超滤膜过滤器27、第二精密过滤器26、第一精密过滤器25、粗过滤器24进行反洗，超滤膜过滤器27反洗产生的废水可直接流入第二精密过滤器26用于对第二精密过滤器26进行反洗，也可通过直连管道233流入粗过滤器24用于对粗过滤器24进行反洗，第二精密过滤器26反洗产生的废水通过第三过滤水管215直接流入第一精密过滤器25用于对第一精密过滤器25进行反洗，第一精密过滤器25反洗产生的废水可直接通过第一反洗水管228直接流入第一沉淀池21，也可通过第二过滤水管214流入粗过滤器24用于对粗过滤器24进行反洗，粗过滤器24反洗产生的废水通过第二反洗水管229直接流入第一沉淀池21
3、反洗完成后，关闭手动补水阀门223即可。
最后，需要注意的是，以上列举的仅是本发明的具体实施方式。显然，本发明不限于以上实施方式，还可以有很多变形。本领域的普通技术人员能从本发明公开的内容中直接导出或联想到的所有变形，均应认为是本发明的保护范围。
