Description

一种超高压前混合磨料射流智能连续供料系统 技术领域
本发明涉及一种超高压前混合磨料射流智能连续供料系统，尤其适用于超高压前混合磨料射流连续作业。
背景技术
20世纪80年代，在纯水射流的基础之发展出磨料射流，与纯水射流相比较，磨料水射流的切割能力大大提高，因此其广泛应用于工业切割、岩石掘进、表面清洗和钻探开采。根据加料的方式不同，磨料水射流可以分为前混合磨料水射流和后混合磨料水射流。由于后混合磨料水射流不能使磨料与高速流动的水进行充分的混合，明显降低了水介质对磨料的传输效率，因此在相同能耗的情况下，后混合磨料水射流的切削能力远远低于前混合磨料水射流的切削深度。所以对于前混合磨料水射流的研究就成为磨料水射流研究的重点，但是长期以来前混合磨料水射流应用中一个关键性的问题就是磨料很难实现连续供应的问题。
在现有的技术中，前混合磨料水射流大多数采用双罐切换式实现磨料的连续供应，这种供应方式也很难完全的避免停机切换，并且在添加磨料的过程中仍需放压，高压接头经常拆卸容易使可靠性降低带来安全隐患，且增加了设备的磨损，使工作效率在一定程度上有所降低。
发明内容
为了克服现有的上述不足，本发明提供一种超高压前混合磨料射流智能连续供料系统，该系统能够实现超高压前混合磨料射流连续供料且无需降压。
本发明解决其技术问题采用的技术方案是：包括高压水箱、安全阀、分 水阀，高压水箱经安全阀与分水阀连通，所述分水阀的三个出口分别连接第一水路、第二水路和第三水路；第一水路经减压阀与电磁换向阀入水口相连通，第二水路经截止阀Ⅱ接入混料阀，第三水路经截止阀Ⅰ与安装在超高压混料罐上部的双流道接头连接；在超高压混料罐的垂直上方还依次串联有超高压储料罐和供料斗；在超高压混料罐的底部安装有下部流道阀，下部流道阀和混料阀分别与截止阀Ⅲ的进出口相连通；在超高压混料罐外部对称位置还固定有声发射源和声发射检测传感器，声发射检测传感器与信号处理单元连接，同时还依次连接控制器及电磁换向阀，电磁换向阀出水口与固定在超高压储料罐侧部的水马达相连通，水马达输出轴上的齿轮与换向齿条的中部齿带啮合，换向齿条的上部齿带与齿轮截止阀Ⅱ啮合，换向齿条的下部齿带与齿轮截止阀Ⅰ啮合；供料斗与超高压储料罐通过齿轮截止阀Ⅱ相连接，超高压储料罐通过齿轮截止阀Ⅰ与双流道接头相连接。
相比现有技术，本发明的一种超高压前混合磨料射流智能连续供料系统，采用超高压混料罐、超高压储料罐、供料斗垂直串联方式，通过换向齿条智能地间隙性切换超高压混料罐与超高压储料罐之间齿轮截止阀、超高压储料罐与供料斗之间齿轮截止阀，实现了超高压前混合磨料射流连续供料且无需降压。系统输出压力稳定，执行元件采用水介质动力元件无需其它辅助动力源，结构紧凑，安全可靠。

工作原理及过程：
高压水箱1中的高压水经分水阀3分流进三条水路：第一水路4经减压阀31与电磁换向阀21入水口相连通，第二水路5经截止阀Ⅱ8接入混料阀9，第三水路6经截止阀Ⅰ7与安装在超高压混料罐11上部的双流道接头1O的直角左侧流道1O-1连接。下部流道阀12安装在超高压混料罐11的底部，截止阀Ⅲ13的进出口分别与下部流道阀12和混料阀9相连通，第三水路6中的高压水经截止阀Ⅰ7和双流道接头1O的直角左侧流道1O-1注入到超高压混料罐11中，形成的超高压水携带沉积在超高压磨料罐底部的磨料Ⅰ26经磨料入口12-2进入下部流通阀12的L型流道12-5，再流经截止阀Ⅲ13进入混料阀9，在混料阀9中与第二水路5中的高压水混合成超高压前混合磨料浆体14。
根据声发射检测传感器25信号判断声发射源24和声发射检测传感器25之间的介质为高压水1或磨料Ⅰ26，确定超高压磨料罐11中沉积的磨料Ⅰ26高度。超高压混料罐11内沉积的磨料Ⅰ26高度低于声发射源24的高度 时信号处理单元23向控制器22发出指令经电磁换向阀21利用水马达2O驱动换向齿条19依次关闭超高压储料罐17与供料斗18之间的齿轮截止阀Ⅱ16和开启超高压混料罐11与超高压储料罐17之间的齿轮截止阀Ⅰ15，超高压储料罐17内的磨料Ⅱ27自动沉降至超高压混料罐11，磨料Ⅱ27沉降后通过换向齿条19依次关闭超高压混料罐11与超高压储料罐17之间的齿轮截止阀Ⅰ15和打开超高压储料罐17与供料斗18之间的齿轮截止阀Ⅱ16向高压储料罐11注入磨料Ⅱ27，重复上述过程即可不断向超高压混料罐11沉降磨料Ⅱ27。当检测到沉积磨料Ⅰ26的高度高于声发射源24时，通过控制器22发出指令经电磁换向阀21利用水马达2O驱动换向齿条19依次关闭超高压混料罐11与超高压储料罐17之间的齿轮截止阀Ⅰ15和打开超高压储料罐17与供料斗18之间的齿轮截止阀Ⅱ16。
本发明实施例通过上述的过程实现前混合磨料的智能连续供给，系统安全可靠，工作效率高。
以上所述，仅是本发明的较佳实施例，并非对本发明做任何形式上的限制，凡是依据本发明的技术实质，对以上实施例所做出任何简单修改和同等变化，均落入本发明的保护范围之内。
