Description

防溢流机构 技术领域 本实用新型涉及粪便的取运便装置领域, 特别地, 涉及一种用于取运便装置上的 防溢流机构。 背景技术 针对贮便的取运, 现行普遍使用的取运便装置为真空吸粪车。 真空吸粪车在取便 时, 真空取便系统需要连通载运槽体与真空取便系统的气体通道支持将载运槽体中的 气体抽出形成真空后,贮便体中的贮便受大气压力作用, 由贮便体转移到载运槽体中, 实现贮便的真空抽取, 如果载运槽体被粪便污水满贮前不能及时终止取便操作, 则载 运槽体中的粪便污水有可能经连通载运槽体与真空取便系统的气体通道进入到真空取 便系统中, 损坏真空取便系统。 真空吸粪车在用于非吸粪的其它吸污作业情况, 也同 样存在类似问题。 真空吸粪车对此采取的解决办法为在连通载运槽体与真空取便系统的气体通道的 与载运槽体相接的通道前端设置溢流阀。 溢流阀属于一个带有浮子单向阀的装置,其作用是当被吸粪便污水快满罐时,由于 浮子的作用将单向阀顶向装置的吸气口,在浮子及真空吸力的共同作用下,关闭吸气 口. 有效防止载运槽体内的粪便污水吸入真空泵管路及真空泵。 该结构的弱点在于, 在崎岖道路及所取粪便污水满槽情况下行驶中的槽内所存粪 便污水是容易产生波动的, 而波动的粪汁对溢流阀中的浮子单向阀的作用无法恒定, 而且行驶过程并无真空吸力对浮子单向阀的作用, 故此情况, 粪便污水有可能进入溢 流阀内部, 或者说溢流阀的单向阻断失效, 这部分粪便污水虽说不能直接流入真空取 便系统, 但留存于溢流阀内的哪怕是少量粪便污水物质, 也会在下一次吸粪时被吸入 气流带进真空取便系统。 此外, 连通载运槽体与真空取便系统的气体通道于载运槽体上的装置位置也容易 促成上述粪便污水有可能进入溢流阀内部, 或者说导致溢流阀的单向阻断失效情况发 生。 原因在于, 连通载运槽体与真空取便系统的气体通道均设于载运槽体顶部的近前 端, 当吸粪车行驶于下坡状态, 即使载运槽体所取粪便污水并未满槽, 但由于处于下 坡状态, 槽内粪便污水会涌向载运槽体的前部, 使载运槽体前部处在满槽状态, 再加 行驶过程中的颠簸弓 I发粪水激荡, 粪便污水也很有可能进入溢流阀内部。 还有一值得注意的现象是, 吸粪时,进入载运槽体中的粪便污水是有溅射现象的, 因溅射而飞起的粪滴有可能被抽气时的高速气流裹挟带入溢流阀, 进而进到真空取便 系统, 此时由于粪便污水并未满槽, 溢流阀中的浮子单向阀无法发挥阻断作用。 此外, 中国在先专利申请, 申请号: 00113266.0, 公开日: 2001年 10月 10日, 其中公开了正压取便和以正压取便为基础的双压取便系统装置。 基本原理在于将压力 空气充注到封闭贮便体内, 通过压力空气作用将贮便送入载运槽体, 实现取便, 装备 有这类取便系统的取便车可称之为压力空气取便车。 针对压力空气取便车同样存在满 槽、 颠簸行驶、 下坡以及溅射飞起粪滴各种情况下对压力空气取便系统保护的问题。 实用新型内容 本实用新型的目的在于提供一种取代传统溢流阀, 并改变其装置位置, 使针对真 空吸粪车包括压力空气取便车, 无论其在满槽、 颠簸行驶、 下坡以及取便时溅射飞起 粪滴各种情况下对压力空气取便系统都能实现对其取便系统的保护的防溢流机构, 以 解决现有技术中的压力空气取便车在满槽、 颠簸行驶、 下坡以及溅射飞起的粪滴污染 取运便装置的技术问题。 为实现上述目的, 本实用新型的一个方面, 提供了一种防溢流机构, 包括载运槽 体, 载运槽体顶部外部设置曲径气道装置, 载运槽体内部经曲径气道装置实施与取便 系统的气体联系; 曲径气道的结构取为: 竖置中空管状体, 管状体内部由管道下端管 口构成的气道口以上部位设置有两片或两片以上与竖直方向交角呈非直角状的交替互 设气道挡板, 且所设气道挡板的悬置端与所面对的管道内壁以及与相邻气道挡板为非 接触, 经气道挡板将管状体内部空间分隔成曲折气道; 管状体上端端口设封口体, 于 封口体上设置与真空吸粪车的真空取便系统或压力空气取便车的压力空气取便系统连 通的管道。 进一步地, 曲径气道设于载运槽体顶部外部的中部或近中部。 进一步地, 曲径气道位于载运槽体内部的气道口的下方设置防溢流机构, 防溢流 机构取为,在曲径气道位于载运槽体内部的气道口下方设置由笼栅和笼底构成的栅笼, 栅笼内安置由中空结构浮体构成的浮塞, 自由状态的浮塞受自身重力作用落于笼底, 曲径气道气道口呈开放状态; 当载运槽体因所取粪便污水充满时, 浮塞受粪便污水浮 力和笼栅约束作用将曲径气道装置位于载运槽体内部的气道口堵塞。 为实现上述目的, 本实用新型的另外一个方面, 提供一种防溢流机构, 且安装载 运槽体上, 防溢流机构包括安装在载运槽体上, 且和载运槽体贯通的管状体及安装在 管状体内的至少两个挡板; 每一挡板通过第一端倾斜地安装在管状体的内壁面, 且每 一挡板的与第一端相对的一端为悬置端, 每相邻的两个挡板的悬置端之间相互间隔交
进一步地, 管状体包括位于载运槽体内的气道口; 载运槽体内与气道口相对的位 置设置有至少两个笼栅, 笼栅的底端设有笼底, 且笼底和笼栅共同构成一个栅笼; 防 溢流机构还包括一个置于栅笼内的浮塞, 浮塞可浮起地堵塞气道口。 进一步地, 每一笼栅的侧面设有滑槽, 浮塞的端缘安装在对应的滑槽内, 且可沿 着滑槽滑动。 进一步地, 浮塞的边缘设有卡口, 卡口卡合在对应的笼栅上, 且浮塞可沿着笼栅 滑动。 进一步地, 管状体的与气道口相对的一端还设有封口体, 封口体上安装有一个与 管状体的内部贯通的外联管道。 进一步地, 载运槽体的顶部固定设有一个板体, 管状体固定在板体上, 且管状体 穿过板体后与载运槽体贯通。 进一步地, 管状体的轴心线与载运槽体的竖直方向的中心线相互靠近或重合。 本实用新型具有以下有益效果: 本实用新型的防溢流机构的管状体设于载运槽体 顶部外部的中部或近中部, 该管状体内交叉设有多个挡板, 使正常载运条件下, 无论 槽车载运过程的上坡或下坡中出现的溅射飞起粪滴与载运过程激荡的粪便污水难以进 入该管状体内; 且安装在载运槽体的内部可以堵塞该管状体的气道口的浮塞, 在载运 槽体的内部充满粪便时, 利用浮力的作用而堵塞该管状体的气道口, 可有效阻止载运 槽体中的载运粪便污水进入取便系统, 确保取便系统的安全运行。 除了上面所描述的目的、 特征和优点之外, 本实用新型还有其它的目的、 特征和 优点。 下面将参照图, 对本实用新型作进一步详细的说明。 附图说明 构成本申请的一部分的附图用来提供对本实用新型的进一步理解, 本实用新型的 示意性实施例及其说明用于解释本实用新型, 并不构成对本实用新型的不当限定。 在 附图中: 图 1是本实用新型防溢流机构的优选实施例的结构示意图。 具体实施方式 以下结合附图对本实用新型的实施例进行详细说明, 但是本实用新型可以由权利 要求限定和覆盖的多种不同方式实施。 请参照图 1, 本实用新型防溢流机构的优选实施例安装于取运便装置 (图未示) 的载运槽体 10的顶部, 且和载运槽体 10的内部相贯通。 该防溢流机构包括管状体 2、 两片以上挡板 3、 气道口 6, 封口体 4、 及外联管道 5。 载运槽体 10的顶部固定设有一个板体 1。 该板体 1直接固定在载运槽体 10在顶 部的外表面或者固定在载运槽体 10的顶部处的塔筒上,还或者固定在塔筒的塔筒盖板 上。 管状体 2装置于载运槽体 10上的板体 1的外表顶面, 且该管状体 2穿过该板体 1 后与载运槽体 10贯通。 管状体 2的一端进口为气道口 6, 且属于管状体 2的气道口 6 位于板体 1的里表, 即是; 该气道口 6位于载运槽体 10内。 优选地, 管状体 2的轴心 线和载运槽体 10的竖直方向的中心线重合,或靠近载运槽体 10的竖直方向的中心线; 即是: 管状体 2设于载运槽体 10的顶部外部的中部或近中部。 两片以上的挡板 3交替互设于管状体 2, 且这些挡板 3均位于管状体 2的位于板 体 1上方的内部空间。 每一挡板 3的第一端倾斜地安装在管状体 2的内壁面, 且每一 挡板 3的和该第一端相对的一端为悬置端。 每一挡板 3的悬置端与所面对的管状体 2 内壁以及与相邻挡板均互不接触,且每相邻的两个挡板 3的悬置端之间相互间隔交叠。 这样, 经挡板 3将管状体 2的内部空间分隔成曲折气道。 因此, 由于该管状体 2内部 的曲径气道的结构设计, 使取便过程可能出现的溅射飞起粪滴与载运过程激荡的粪便 污水难以进入该管状体 2内, 或进入该管状体 2内后, 由于受挡板 3阻挡, 而回落至 载运槽体 10内;更因为挡板 3的有倾斜角度结构,使其不易在该管状体 2中形成潴积, 而是会自动流回至载运槽体 10的内部。 封口体 4设置在管状体 2的与气道口 6相对的一端。 封口体 4上设有安装孔 (未 标号)。该外联管道 5安装在封口体 4的安装孔上, 且和管状体 2的内部相连通。外联 管道 5与真空吸粪车的真空取便系统, 或空气压力取便槽车的压力空气取便系统相连 通。 更加优选地, 本实用新型的防溢流机构还包括至少两根栅笼 7和浮塞 8。 该至少 两根笼栅 7设置在板体 1内壁底面, 且位于载运槽体 10内、并与气道口 6相对应的位 置。 笼栅 7的下端部设置有笼底 9, 笼栅 7和笼底 9一起构成栅笼。 浮塞 8的边缘上 设有滑动卡合在对应笼栅 7上的卡口 (图未示), 且浮塞 8可沿着笼栅 7上下滑动。这 样, 中空结构的浮塞 8置于栅笼内, 受重力和浮力作用以及笼栅 7的约束在栅笼内可 作上下移动。 自由状态的浮塞 8受自身重力作用落于栅笼笼底 9; 当取便充满载运槽 体 10时,浮塞 8受粪便污水浮力作用和笼栅 7约束浮起并将管状体 2的气道口 6堵塞, 以防止载运槽体 10中的载运粪便污水溢流至管状体 2后经过外联管道 5流入真空吸粪 车的真空取便系统, 或空气压力取便槽车的压力空气取便系统, 而污染真空吸粪车的 真空取便系统, 或空气压力取便槽车的压力空气取便系统, 以确保取便系统的安全运 行。 优选地, 在其它实施方式中, 每一笼栅 7的侧面设有滑槽, 浮塞 8的端缘安装在 这些滑槽内, 且可沿着这些滑槽的上下滑动, 以对浮塞 8的移动起导向作用。 以上所述仅为本实用新型的优选实施例而已, 并不用于限制本实用新型, 对于本 领域的技术人员来说, 本实用新型可以有各种更改和变化。 凡在本实用新型的精神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本实用新型的保护范围 之内。
