纯硅收集模块：接收投料模块的触发信号，处理后对硅渣处理容器中沉淀的纯硅进行收集；
杂质收集模块：接收投料模块的触发信号，处理后对硅渣处理容器中悬浮的杂质进行收集；
现场监控模块：对硅渣处理容器进行检测，并将检测信号作为反馈信号发送给搅拌控制器。处理器根据外界输入的控制参数输出控制信号到现场控制器，外界输入的控制参数如：使500kg硅渣在2000L悬浊液中进行浮选，现场控制器根据处理器发送的信号向悬浊液控制器发出注入2000L悬浊液的控制信号、向投料模块发送投入500kg硅渣的控制信号、向搅拌控制器发出开始工作的控制信号，悬浊液控制器根据现场控制器的控制信号控制悬浊液注入模块向硅渣处理容器中注入配置好的铁粉悬浊液2000L，流量检测模块检测悬浊液的注入过程作为反馈信号发送给悬浊液控制器，便于悬浊液控制器对悬浊液注入模块进行调整，投料模块根据现场控制器的控制信号向硅渣处理容器中投入粉碎好的硅渣500kg，同时投料完成后向纯硅收集模块和杂质收集模块发送触发信号，搅拌控制器根据现场控制器的控制信号和现场监控模块的反馈信号驱动搅拌模块对硅渣处理容器进行搅拌，搅拌控制器根据现场监控模块发送的信号在两种搅拌模式中进行选择，当现场监控模块检测到硅渣处理容器内混合物的质量上升时，采用投料搅拌模式，否则采用分离搅拌模式，纯硅收集模块和杂质收集模块接收到投料模块发送的触发信号后开始从硅渣处理容器中收集纯硅和硅渣，纯硅收集模块和杂质收集模块采用延时控制，在接收到投料模块发送的触发信号后，延时器开始工作，延时 器工作完成后触发纯硅收集模块和杂质收集模块开始工作。操作人员根据以往操作的经验得出在硅渣投入硅渣处理容器后多长时间后纯硅沉淀完成，如在投料后30min纯硅就沉淀95％以上，剩下的5％沉淀极为缓慢，则将30min作为延时器的延时时间输入到纯硅收集模块和杂质收集模块的延时器中，当纯硅收集模块和杂质收集模块接收到投料模块发送的触发信号后，延时器开始工作；现场监控模块检测硅渣处理容器、纯硅收集模块和杂质收集模块的工作状态，并发送给处理器，处理器根据现场监控模块发送的现场工作状态以及外界输入的控制参数判断系统是否正常运行。所述现场监控模块还与处理器连接，现场监控模块包括称量装置和液位传感器，对硅渣处理容器进行监控，监控硅渣处理容器质量和其中混合物体积的变化，与处理器发送的信号进行对比，判断系统是否正常运行。
