附图说明
通过以下参照附图对本发明实施例的描述，本发明的上述以及其它目的、特征和优点将更为清楚，在附图中：
附图1为本发明提供的动车组卫生间灰水再利用装置的结构示意图。
具体实施方式
以下基于实施例对本发明进行描述，但是本发明并不仅仅限于这些实施例。
如图1所示，图1为本发明提供的动车组卫生间灰水再利用装置的结构示意图。
本实施例提供了一种动车组卫生间灰水再利用装置，包括对灰水进行收集和过滤的灰水收集装置1，将过滤后的灰水导出的水泵安装单元2，与水泵安装单元2连通并储存过滤后的灰水的中水箱安装单元3，中水箱安装单元3的出水端连通至便器水增压器4。动车组内产生的灰水，导通至灰水收集装置1并在其内进行灰水过滤，去除灰水内材质，过滤后的灰水经水泵安装单元2泵出，储存至中水箱安装单元3内，中水箱安装单元3连通便器水增压器4，实现灰水的再利用。通过灰水收集装置1对动车组内灰水的收集和过滤，并由水泵安装单元2和中水箱安装单元3进行灰水的泵出和储存，实现了对灰水的循环再利用。
在本案一具体实施例中，灰水收集装置1包括上层净水区12和下层灰水区11，还包括连通上层净水区12和下层灰水区11，对灰水进行过滤的过滤装置13；水泵安装单元2连通上层净水区12。灰水来自于洗池5和地漏，灰水收集的过程中，会形成颗粒物杂质淤积，为了避免杂质堵塞，将灰水收集装置1设置为上层净水区12和下层灰水区11，二者之间由过滤装置13连通，灰水首先进行下层灰水区11，其内混入的杂质受重力分层，并静置后，顶部的灰水继续由过滤装置13过滤后进入上层净水区12。水泵安装单元2连通上层净水区12，上层净水区12的净水通道14由上层净水区12的底部将上层净水区12内过滤的灰水抽出，由于下层灰水区11内灰水的自动分层和过滤装置过滤，去除过滤后灰水内的杂质。
灰水收集装置1内采用上下分层的灰水区和净水区，利用灰水的重力进行灰水的初步过滤，可以理解，灰水收集装置1的高度应低于洗池5或水漏流 通管路的高度，易于灰水的收集。
在本案一具体实施例中，灰水收集装置1的顶部设置有连通下层灰水区11，对下层灰水区11进行排气和溢流的灰水溢流排气通道15。灰水经灰水管路流入到灰水收集装置1，同时灰水需要经过滤装置13由下层灰水区11进入上层净水区12，由灰水溢流排气通道15连通灰水收集装置1的顶部，保证灰水收集装置1与外部灰水管路之间压差，避免其内气压增大影响灰水流入，同时，当灰水收集装置1内注满后，多余灰水可直接由灰水溢流排气通道15排出到动车组外部。
在本案一具体实施例中，灰水收集装置1的侧壁顶部设置有与灰水溢流排气通道15连通，对下层灰水区的液位进行监测的灰水液位传感器16；和对上层净水区12的最高液位进行监测的净水液位传感器17。灰水液位传感器16位于灰水收集装置1顶部，并与灰水溢流排气通道15连通，当灰水收集装置1内注满后，可通过灰水溢流排气通道15将灰水排出，或者直接将灰水排入至污物箱，保证动车组内部灰水的正常排出。
上层净水区12设置净水液位传感器17，对其内过滤后的灰水进行监测，一方面可保证上层净水区12保证足够的过滤后灰水，满足后续的灰水供水，同时起到及时监测上层净水区12水量，实现对灰水流向的及时控制。
在本案一具体实施例中，过滤装置13为三级过滤器。过滤装置13对洗池和地漏的灰水直接过滤，灰水静置、分层的方式难以去除灰水内杂质，将三级过滤器设置位于上层净水区和下层灰水区之间，保证灰水过滤效果，避免后续管路堵塞。三级过滤器包括初级过滤层、二级过滤层和碳纤维过滤层，进一步保证过滤效果。
在本案一具体实施例中，还包括与下层灰水区11连通的污物箱6，污物箱6的前端管路上设置有当灰水液位传感器16触发时控制开启的管夹阀7。动车组内设置污物箱6，由洗池5或地漏流出的灰水同时连通灰水收集装置1和污物箱6，当灰水收集装置1正常工作时，灰水直接流入，由管夹阀7断开灰水管路与污物箱7的连通。当灰水收集装置1内注满后，灰水液位传感器16触发，此时一部分灰水由灰水排气溢流通道15可直接排出，当水泵安装单元2和中水箱安装单元3均不需要补充过滤后的灰水时，后续的灰水可直接排入到污物箱6，满足灰水的收集要求。
同时，由于灰水收集装置1的下层灰水区11持续收集灰水，其内容易形成固体杂质淤积，通过灰水收集装置1和污物箱6直接连通，可通过控制管夹阀7的开启，将下层灰水区11内淤积的杂质收集到污物箱6内，避免对外部环境污染。灰水收集装置1内的杂质，可利用车供气源提供压力或通过真空吸附的方式送入污物箱内。
在本案一具体实施例中，水泵安装单元2包括与上层净水区12连通的净水管路，顺序设置于净水管路上的二级过滤器22和水泵21。水泵安装单元2用于对上层净水区12内过滤灰水的抽取，其上设置连通灰水收集装置1的净水管路，过滤后的灰水进入水泵21前，由二级过滤器22进行二次过滤，后经水泵21泵出后送入到中水箱安装单元3。
具体地，中水箱安装单元3包括与水泵21的出水管路连通的中水箱，中水箱的底部和顶部分别设置有对其低液位进行监测的低液位传感器32，和对其高液位进行监测的高液位传感器31，中水箱的顶部还设置有溢流口。中水箱安装单元3由其上中水箱连通水泵的出水管路，通过中水箱储存二次过滤后的灰水，保证足够的灰水量，满足便器的使用要求。中水箱内设置高液位传感器31和低液位传感器32，低液位传感器32和高液位传感器31对中水箱内灰水量进行监测，高液位传感器31触发时，说明中水箱内有足够水量，此时无需控制水泵安装单元2进行供水，当低液位传感器32触发时，说明中水箱内水量较少，需要水泵安装单元工作，将灰水收集装置内的灰水进行抽出存储。
在本案一具体实施例中，中水箱还连通有车供水源管路8。当灰水收集装置1内没有足够的灰水进行供应，同时中水箱内储存的水量不足时，将无法对便器水增压器4进行供水，通过将中水箱直接连通车供水源管路8，控制车供水源管路8的通断，提供便器水增压器4足够的工作水量。本实施例提供的灰水再利用装置充分利用车上空间，采用独立于车供水源管路的集便系统，即使该系统不可用，可以直接依靠车上原供水系统供水，兼容性好。
在本案一具体实施例中，还包括与灰水收集装置1、水泵安装单元2和中水箱安装单元3电联接，控制灰水流通的控制单元9。为了充分利用动车组内空间，水泵安装单元2和中水箱安装单元3可共用同一灰水收集装置水盘，二者分别位于水盘两侧。
在集便系统基础上增加包含过滤装置的灰水收集装置1、包含控制器的控 制单元9、包含水泵安装单元和中水箱安装单元的灰水收集装置水盘，利用车上空间及现有资源收集洗手盆旅客用水，通过收集、过滤后用于便器冲洗，实现灰水的再利用，由控制单元接收灰水收集装置和中水箱上的液位传感器信号，在灰水能够利用的情况下，第一时间切换选择灰水，节约车供水源管路内清水的使用。
洗手盆的灰水经过滤装置过滤后流入中水箱，此时车供水源管路上的截止阀处于截止状态；中水箱内安装有高液位传感器和低液位传感器，当水量达到设定液位时激活，将灰水箱内的水导入便器水增压器内用于冲洗。
中水箱还设置有溢流管路，当中水箱内注满时，多余的水通过溢流管路排到车下，如果中水箱内水量不足，中水箱与便器水增压器之间的管路处于关闭状态，车供水源管路内的清水将直接注入便器水增压器内，确保足够的冲洗用水。
通过灰水收集装置对灰水进行循环利用，不仅可以保护环境、节省能源，而且可以减少动车组污物箱和净水箱容积的设置，有利于动车组的整车的轻量化设计。
当然，本实施例提供的灰水再利用装置具有故障显示功能，系统故障时，控制单元会在灰水收集装置控制盘上显示故障代码，帮助维修人员排除故障。
以上所述仅为本发明的优选实施例，并不用于限制本发明，对于本领域技术人员而言，本发明可以有各种改动和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
