Description

除尘系统和扫路车
技术领域
本发明涉及湿式除尘, 具体地, 涉及一种除尘系统和扫路车。 背景技术
扫路车具有湿式除尘和扫路功能, 具有清扫速度快、 环境污染小、 清洁 效率高等优点。 其中, 扫路车包括除尘系统, 该除尘系统包括分别设置在车 体上的扫盘、 吸嘴、 弹性伸缩管、 吸管、 垃圾箱和用于提供抽吸气流的抽吸 装置(例如吸风机)等。 扫盘通过安装在扫盘上的扫刷清扫路面的灰尘和垃 圾。 为了避免作业扬尘, 造成空气污染, 扫路车一般都在扫盘上部、 吸嘴内 部设有喷水装置, 该喷水装置所需的加压清洁水由车体自带的水箱和洒水系 统提供。 作业时, 设置在扫盘上部的喷水装置喷出的雾化清洁水首先对路面 上的泥土、 粉尘、 垃圾物等进行喷水预湿。 然后, 扫刷将这些被湿润的垃圾 物扫至吸嘴正前方, 在抽吸装置提供的抽吸作用下, 携载湿润的垃圾物的气 流 (以下简称含尘气流) 经吸嘴、 弹性伸缩管、 吸管被吸入垃圾箱。 在该过 程中, 设置在吸嘴内部的喷水装置喷出的雾化清洁水对流经吸嘴的湿润的垃 圾物再次进行喷水处理,从而经过前后两次喷水湿化使扫路车的作业扬尘得 到了有效的控制。
为了使抽吸流体的流动更加通畅, 减少含尘气流对吸风机的磨损, 扫路 车一般都采用吸风机后置的布局方式。 也就是将垃圾物喷水湿化后, 经由吸 嘴和吸管等, 在吸风机抽吸的作用下吸入垃圾箱。含尘气流只有经过在垃圾 箱中进行垃圾物沉降处理后,其中的气体才能进入吸风机并通过排风出口排 放到大气中。 在上述含尘气流的流动通道中, 由于吸嘴内部设有喷水装置, 并且含尘气流的负压和速度都非常高,因而过流表面(含尘气流流过的表面) 不容易产生粘堵现象。 由于扫路车在行驶过程中的车体颠簸和吸嘴跳动的共 同作用, 弹性伸缩管持续抖动, 其过流表面也不会产生粘堵现象。 但吸管容 易产生粘堵, 主要原因有以下二个方面:
一方面: 为了能使垃圾物在垃圾箱中合理分布, 吸管整体上向后倾斜了 一定角度。 充分湿化的垃圾物的混合物料在高速负压气流的作用下, 与水分 子、 气流交织在一起。 经过吸嘴、 特别是经过弹性伸缩管的波紋状表面后, 由于受到过流表面内磨擦力的影响, 使紧贴在吸管内壁及内壁周围的含尘气 流的负压和速度急剧下降。此时,一部份体积或密度较大的垃圾物混合物(如 粘性泥团)掉落并紧紧地粘附在倾斜吸管的内壁上, 随着使用时间延长会越 积越多并彼此交叉, 最终使吸管的过流面积逐渐减小甚至完全堵死。
另一方面: 倾斜安装在车体上的吸管随车体同步向前运动。 此时, 倾斜 吸管内高速运动的体积或密度较大的垃圾物混合物(如粘性泥团)或将与吸 管内壁发生碰撞。 发生碰撞的垃圾物混合物 (如粘性泥团)撞击并紧紧地粘 附在吸管内壁上, 导致越积越多并硬化成层。 这样既会造成吸管内壁粗糙又 会导致输送阻力增加, 势必在输送到一定程度之后发生堵塞现象。
吸管内壁发生粘堵或堵塞现象后, 不易觉察, 影响路面清洁效果。 而且 由于硬化得很密实, 所以很难清理出来, 给使用维护带来了很大的不便。 发明内容

以下结合附图对本发明的具体实施方式进行详细说明。 应当理解的是, 此处所描述的具体实施方式仅用于说明和解释本发明, 并不用于限制本发 明。
在本发明中, 在未作相反说明的情况下, 使用的方位词如"上、下、左、 右"通常是指参考附图所示的上、 下、 左、 右; "内、 外"是指相对于各部 件本身的轮廓的内、 夕卜。
本发明的除尘系统包括依次连通的抽吸装置、 垃圾箱 10、 吸管 20和吸 嘴 30, 其中, 所述吸管 20上设置有过水孔 23, 所述除尘系统还包括通过所 述过水孔 23为所述吸管 20供水的供水装置。
使用时,抽吸装置产生的负压使得含尘气流从吸嘴 30经过吸管 20流到 垃圾箱 10中。 与此同时, 供水装置通过过水孔 23为吸管 20供水, 水继而 随所述含尘气流沿吸管 20流到垃圾箱 10中, 在流动过程中, 一部分水会接 触并湿润吸管 20的内壁, 一部分水会使含尘气流中的湿润的垃圾物更加湿 润, 从而使体积或密度较大的垃圾物混合物稀释以使其粘性降低。 因此, 一 方面可以通过湿润吸管 20的内壁而使得吸管 20的内壁的摩擦系数降低, 另 一方面可以降低含尘气流中携载的湿润的垃圾物的粘性,从而降低与吸管 20 的内壁气流中携载的湿润的垃圾物的摩擦力。 其中, 供水装置可以采用各种适当的形式, 只要能够通过过水孔 23为 吸管 20供水即可。 此外, 水可以是纯净的清水。 在本发明的一种实施方式 中, 所述供水装置包括与所述过水孔 23连通的储水容器。 可以在该储水容 器中储存纯净的清水, 从而通过过水孔 23提供到吸管 20中。
优选地, 在本发明的一种优选实施方式中。 可以利用收集在垃圾箱 10 中的湿润的垃圾物所含的污水。 具体地, 如图 1和图 2所示, 所述供水给装 置包括过滤装置 50,所述垃圾箱 10的内部通过所述过滤装置 50分为垃圾区 10a和过滤水区 10b, 所述过滤水区 10b与所述过水孔 23连通。 通过这种布 置, 气流中携载的湿润的垃圾物在垃圾箱 10中沉降, 湿润的垃圾物中的污 水可以通过过滤装置 50分离到过滤水区 10b中,垃圾物则分离到垃圾区 10a 中。 污水经过过滤装置 50的过滤后可以形成过滤水, 过滤水可以代替清水 通过过水孔 23提供到吸管 20内, 以用于湿润吸管 20的内壁并稀释体积或 密度较大的垃圾物混合物。 另外, 过滤水可以随含尘气流流回垃圾箱 10并 再经过滤装置 50过滤而回到过滤水区 10b, 从而能够实现循环利用。
过滤装置 50可以采用各种适当的结构,只要能够将垃圾箱 10内的湿润 的垃圾物分离为垃圾物和过滤水并使该垃圾物和过滤水分别保持在垃圾区 10a和过滤水区 10b中即可。
在本发明的一种实施方式中, 所述过滤装置 50包括连接到所述垃圾箱 10侧壁的隔板 51和连接到所述隔板 51的过滤板 52,所述隔板 51具有开口 51a, 所述过滤板 52从所述开口 51a的至少一侧边缘向上延伸, 所述隔板 51 和所述过滤板 52将所述垃圾箱 10的内部分隔为所述垃圾区 10a和过滤水区 10b。
通过设置隔板 51,可以承接从吸管 20吸入垃圾箱 10的含尘气流中的湿 润的垃圾物。该湿润的垃圾物中的污水将通过从开口 51a的至少一侧边缘向 上延伸的过滤板 52经开口 51a流动到过滤水区 10b, 从而在过滤水区 10b 积累过滤水,过滤水的流动可以参照图 2中的箭头所示。与直接在垃圾箱 10 内布置水平的过滤板相比, 本实施方式的优选结构可以避免垃圾物堆积在过 滤板上并堵塞过滤板。 在本实施方式中, 即使出现垃圾物堆积, 也只会堆积 在隔板 51上, 而不会完全堵塞从开口 51a向上延伸的过滤板 52, 从而保持 过滤装置的过滤功能。
其中, 开口 51a可以形成为各种形状, 并且可以形成在隔板 51的任何 适当的位置上。 过滤板 52可以从开口 51a的至少一侧边缘向上延伸, 从而 污水可以从开口 51a的至少一侧边缘经过滤后流入开口 51a, 以收集在过滤 水区 10b中。 具体地, 多个过滤板 52可以围绕开口 51a的各侧边缘向上延 伸并相交, 从而从侧方和上方包围开口 51a, 则污水可以从开口 51a的侧方 和上方经过滤板 52流入开口 51a。 可选择地, 多个过滤板 52可以围绕开口 51a的各侧便于向上延伸到垃圾箱 10的顶部,从而污水可以从开口 51a的侧 方经过滤板 52流入开口 51a。
在本发明的一种优选实施方式中, 如图 1和图 2所示, 所述开口 51a设 置在所述隔板 51和所述垃圾箱 10的侧壁之间, 所述过滤板 52从所述开口 51a的与所述垃圾箱 10的所述侧壁相对的一侧边缘向上延伸,并且所述过滤 板 52的上边缘和侧边缘分别通过挡板 53连接到所述垃圾箱 10的侧壁, 所 述隔板 51和所述过滤板 52将所述垃圾箱 10的内部分隔为所述垃圾区 10a 和过滤水区 10b。通过这种布置,可以通过挡板 53避免垃圾物直接落在过滤 板 52上, 以防止堵塞过滤板 52, 同时可以简化结构并充分利用空间, 以方 便堆积垃圾物和收集过滤水。
在本发明的优选实施方式中, 如图 1所示, 所述隔板 51在所述垃圾箱 10内倾斜设置, 并沿倾斜方向具有多个所述开口 51a。 由于抽吸装置产生的 负压, 湿润的垃圾物会在特定的位置 (例如在远离下文说明的吸风口 12的 位置, 即图 1中垃圾箱 10右侧) 开始沉降。 通过本实施方式的布置能够在 沉降达到不同水位的时候能够通过不同的开口 51a处的过滤板 52进行过滤。 优选地, 如图 1所示, 所述过滤水区 10b和所述过水孔 23之间可以通 过软管 41连通,从而能够在吸管 20等部件发生轻微振动或位移时,软管 41 可以通过相应的柔性位移来调节连接位置,以确保过滤水区 10b和过水孔 41 的连接不受影响。
优选地, 所述软管 41与所述过水孔 23的连接处具有蓄水部, 从而可以 对不同形状的过水孔或者对多个过水孔提供均匀流量的过滤水。 例如, 过水 孔 23可以形成为圆形、 矩形等, 或者沿吸管 20的外壁形成弧形, 通过蓄水 部可以沿过水孔 23的周缘提供均匀流量的过滤水。
更优选地, 如图 1和图 2所示, 所述软管 43的与所述过水孔 23连接的 端部设置有密封环 42,所述吸管 20的外壁上设置有环形槽 25 (该环形槽 25 可以由从吸管 20的外壁向外凸起的一对环形槽壁限定), 沿所述吸管 20的 周向设置有多个过水孔 23,该多个过水孔 23位于所述环形槽 25中,所述密 封环 42和所述环形槽 25接合以形成所述蓄水部。通过这种布置, 过滤水通 过软管 41 提供到蓄水部并能够从蓄水部均匀地通过各过水孔 23 流入吸管 20, 从而沿周向均匀地湿润吸管 20的内壁。 更优选地, 密封环 42和环形槽 25可以通过密封垫 43密封, 以确保蓄水部能够密封地容纳过滤水。
另外, 过滤板 52可以用于过滤例如最小尺寸为 lmm的杂质, 这取决于 过滤板 52上的过滤孔的尺寸。 此外, 所述供水装置还可以包括过滤器 40, 该过滤器 40连接于所述过滤水区 10b和所述过水孔 23之间, 所述软管 41 的两端分别连接于所述过滤器 40和所述过水孔 23,从而能够为吸管 20提供 更加清洁的过滤水。 过滤器 40可以用于过滤纤维状杂质, 通过这种布置, 可以确保提供到吸管 20的过水孔 23的过滤水中不含纤维杂质, 以避免可能 因含有纤维杂质而过水孔 23或吸管 20。更优选地,可以使过滤器 40的入水 口距离过滤水区 10b底部预定的距离, 以避开经过滤装置 50过滤的水在过 滤水区 10b中自动形成的沉淀。 例如, 可以使过滤器 40的入水口距离过滤 水区 10b底部 5-20cm。 换言之, 通过软管 41供给到过水孔 23的过滤水首 先经过过滤装置 50的粗滤,然后在过滤水区 10b中经自动沉降进一步过滤, 最后经过过滤器 40的精滤方能通过软管 41供给到过水孔 23,从而通过三重 过滤确保提供到吸管 20内的过滤水足够纯净。
所述抽吸装置可以是各种适当类型的能够产生抽吸效果的装置, 例如, 抽吸装置可以是能够产生负压的装置。 优选地, 所述抽吸装置包括吸风机, 所述垃圾箱 10上设置有吸风口 12, 所述吸风机与所述吸风口 12连接。
另外, 如图 1所示, 所述垃圾箱 10设置有可打开的排放口 11, 从而能 够通过打开排放口 11排放污水和沉淀, 并且可以通过排放口 11进入垃圾箱 10进行维护。
根据本发明的另一个方面, 本发明提供一种扫路车, 该扫路车包括车架 80、 扫盘和本发明的除尘系统, 所述扫盘和所述除尘系统分别设置在所述车 架 80上。
此外, 可以在所述吸嘴 30 内设置有第一喷水装置, 并使所述扫盘设置 有第二喷水装置, 以抑制除尘作业产生的扬尘。
其中,第一喷水装置和第二喷水装置可以是各种适于喷出的雾化清洁水 以对泥土、 粉尘、 垃圾物等进行喷水预湿的装置。 例如, 第一喷水装置和第 二喷射装置可以具有相同的结构, 并可以通过相同的供水装置提供清洁水。 关于通过第一喷水装置和第二喷水装置来抑制扬尘是本领域技术人员公知 的技术手段, 在此不做详细说明。
在本发明的一种实施方式中, 如图 1所示, 所述垃圾箱 10和所述吸嘴 30可以分别安装在所述车架上, 所述吸管 20可以包括分别位于所述垃圾箱 10内部和外部的上段 21和下段 22, 所述上段 21可以固定在所述垃圾箱 10 上, 所述下段 22可以固定在所述车架 80上, 所述上段 21和所述下段 22可 以通过密封圈 24密封连接并能够相对枢转, 所述下段 22与所述吸嘴 30连 接, 所述过水孔 23可以设置在所述下段 22上。 通过这种布置, 上段 21可 以随垃圾箱 10—起在一定角度范围内翻转, 而下段 22可以不受影响地相对 于车架 80定位。
此外, 所述扫路车还可以包括升降机构, 所述除尘系统还可以包括弹性 伸缩管 70, 所述下段 22通过所述弹性伸缩管 70与所述吸嘴 30连接, 所述 吸嘴 30通过该升降机构安装到所述车架 80。 通过这种布置, 当本发明的扫 路车处于行驶状态且不进行清扫作业时, 吸嘴 30可以通过升降机构提升到 距离地面一定高度 (例如距离地面 220 mm以上), 以保证车辆无障碍行驶。 此时, 弹性伸缩管 10处于压缩状态。 当本发明的扫路车进行清扫作业时, 吸嘴 30可以通过升降机构下降到工作位置。 此时, 吸嘴 30可以通过行走轮 31支承在路面上并随车辆一起行走, 弹性伸缩管 70处于伸展状态。
以上结合附图详细描述了本发明的优选实施方式, 但是, 本发明并不限 于上述实施方式中的具体细节, 在本发明的技术构思范围内, 可以对本发明 的技术方案进行多种简单变型, 这些简单变型均属于本发明的保护范围。
另外需要说明的是, 在上述具体实施方式中所描述的各个具体技术特 征, 在不矛盾的情况下, 可以通过任何合适的方式进行组合。 为了避免不必 要的重复, 本发明对各种可能的组合方式不再另行说明。
此外, 本发明的各种不同的实施方式之间也可以进行任意组合, 只要其 不违背本发明的思想, 其同样应当视为本发明所公开的内容。
