技术领域
本发明涉及对管道输送的流体介质进行过滤的装置,具体是一种过滤单元在器体外侧的 反清洗过滤器, 能够在各种使用环境下对流体介质中的杂质进行过滤并且可反清洗。
背景技术
现有的反清洗过滤器有滤芯在器体内的, 例如: 中国专利申请(申请号 200620091540.6 和申请号 200910012515.2); 也有滤芯在过滤单元内而过滤单元在器体外侧的,例如: 中国专 利申请 (申请号 200880002878.1 和申请号 200810144808.1 )。 类同专利申请 (申请号 200620091540.6和申请号 200910012515.2) 的几种形式的反清洗过滤器, 其器体中的滤芯一 般为盘片式、 金属缠绕式、 编织网式等可以反清洗的滤芯。 滤芯将介质 (例如水) 中的大于 其过滤精度即大于其滤芯上的孔径(缝隙) 的杂质截留在滤芯上, 完成其过滤功能; 当杂质 截留到一定程度时, 手动或者自动驱动排污装置, 使过滤器中通过某个滤芯的介质流(例如 水) 改变流向, 将截留在滤芯上的杂质反清洗掉, 并排出器体外侧, 完成其反清洗功能。 过 滤器工作一段时期, 无法通过其反清洗功能清洗掉的粘性、 油性杂质在滤芯上增多需要人工 清洗和滤芯或者滤芯上的部件损坏需要检修、 更换, 就必须要将过滤器器体开盖对滤芯进行 人工清洗或者检修。 器体整体开盖的工作量不但大, 而且又非常麻烦, 一般都需要专业的检 修队伍和起重设备, 费用较高。 再有在需要连续供输介质的工艺系统中, 必须设有备用过滤 器, 以备检修时投入使用, 成本高。 类同专利申请 (申请号 200880002878.1 和申请号 200810144808.1 ), 滤芯在过滤单元内而过滤单元在器体外侧的几种形式的反清洗过滤器, 由 于它是采用电磁换向阀、 分配器、 指挥器等各种电气、 液压控制元件控制一换向阀的膜腔液 压力, 让膜片产生位移变化, 使排污口与介质入口的关闭与开启实现转换, 从而使通过某个 过滤单元中滤芯的介质流(例如水) 改变流向, 将截留在滤芯上的杂质反清洗掉, 并排出器 体外侧, 完成其反清洗功能。 为此, 控制元件多, 控制过程繁琐, 所以故障点多、 故障率高, 尤其在含有粘性、 油性微颗粒杂质较大的介质和含有钙镁离子较大的高温水的工作环境中, 各种精密的液压控制元件极其容易被粘性、油性杂质及高温水析出的钙镁离子堵塞,检修率、 故障率更高; 另夕卜, 液压力控制的膜片多为软性胶体材质, 它在高温高压的工况环境中易损 率很高, 致使该种形式的反清洗过滤器在高温高压的工况环境中无法正常使用。

本发明过滤单元在器体外侧的反清洗过滤器的工作过程如下:
( 1 )过滤工作过程: 如图 1、 图 2、 图 7、 图 2-1、 图 7-1所示, 要过滤的介质在管线 自身压力作用下,经进口 4进入滤前介质腔 Q,再通过 N个腔体出口 7与 N个出接口 6对应 相通的管路进入 N个过滤单元的滤前腔 Q1, 经滤芯 20过滤后进入滤后腔 HI; 介质在通过 滤芯 20 时, 如图 10所示, 滤芯 20 为盘片式滤芯, 其过滤方式与中国专利 (专利号: 200880002878.1 ) 中内容相同。 如图 11、 图 12所示, 滤芯 20为金属缠绕式或者为编织网式 等形式滤芯, 介质中大于金属缠绕式滤芯缝隙或者大于编织网式滤芯孔径的杂质, 被阻挡在 滤芯的表面, 如图 1、 图 7、 图 2-1、 图 7-1所示, 被 N个过滤单元中的滤芯过滤后进入滤后 腔 HI的介质通过 N个进接口 8与 N个腔体进口 9对应相通的管路进入滤后介质腔 H,再通 过出口 5进入供输管线中, 完成过滤过程。
(2) 反清洗工作过程: 如图 1、 图 2、 图 7、 图 2-1、 图 7-1所示, 过滤器工作一段时 间, 当被滤芯 20截留的杂质增多阻塞介质流通时,进口 4和出口 5之间出现压力差,此时通 过手动或者电动智能控制打开排污阀 15,驱动驱动装置 16带动连动件 17、排污装置 10动作, 使吸污口 11逐一分别对准器体内的 N个腔体出口 7; 当吸污口 11对准某个腔体出口 7时, 堵住切断了滤前介质腔 Q中要过滤的介质通过这个腔体出口 Ί进入其对应的过滤单元的通 道; 同时, 其对应的过滤单元通过腔体出口 7、 吸污口 11、 排污装置 10、 排污口 101、 集污 装置 12与排污管路 13相通; 此时, 由于排污阀 15打开, 排污管路 13与外界大气相通, 排 污管路 13为放空状态, 过滤单元的滤前腔 Q1成为低压腔, 这样, 通过其它过滤单元过滤后 进入滤后介质腔 H的一部分带压介质通过该过该滤单元对应相通的腔体进口 9反向进入该过 滤单元中, 当由滤后腔 HI经滤芯 20进入滤前腔 Q1时; 如图 10所示, 滤芯 20为盘片式滤 芯, 其反清洗方式与中国专利 (专利号: 200880002878.1 ) 中的方式相同。 如图 11、 图 12 所示,滤芯 20为金属缠绕式滤芯或者为编织网式滤芯,截留在滤芯上的大部分杂质,被介质 流反清洗脱离滤芯的表面, 随反清洗的介质流通过过滤单元 2的单元进口 18、 腔体出口 7、 吸污口 11进入排污装置 10内, 如图 1、 图 2、 图 7、 7-1所示, 再通过排污装置 10—端的排 污口 101进入集污装置 12内,反清洗的介质流进入集污装置 12后再通过排污管路 13排出过 滤器器体 1的外面, 完成该过滤单元滤芯的反清洗过程, 以此类推,驱动驱动装置 16带动连 动件 17、排污装置 10动作, 使吸污口 11逐一分别对准器体内的 N个腔体出口 7, 逐一完成 N个过滤单元滤芯的反清洗。
吸污口增设附件的功能及工作原理: 如图 3、 图 3-1所示, 当过滤器反清洗时, 排污装 置 10带动吸污口 11贴在 N个腔体出口 Ί所在的器体 1内壁的一个环面上作间歇式移动;移 动时, 由于吸污口 11处的弹性胶环 111的弹性作用, 减少甚至避免了排污装置 10带动吸污 口 11在直径较大的器体 1内旋转时, 因为同心度问题而产生的卡滞现象; 当吸污口 11对准 一个腔体出口 7停止移动时, 由于吸污口 11处的弹性胶环 111的弹性作用,使器体 1的滤前 介质腔 Q与在进行反清洗的过滤单元之间的切断效果更好, 反清洗效果更佳; 如图 4、 图 6、 图 4-1、 图 6-1所示, 当过滤器反清洗时, 排污装置 10带动吸污口 11处的管嘴 112在 N个 腔体出口 Ί所在的器体 1内壁的一个环面上间歇式移动,当管嘴 112即吸污口 11对准一个腔 体出口 7停止时, 由于排污管路 13、排污装置 10处于排空状态, 吸污口 11和腔体出口 7内 的介质压力远低于滤前介质腔 Q的压力, 所以在管嘴 112的凸台上有一定的介质压力, 此压 力使管嘴 112在吸污口 11处伸出紧贴在某个腔体出口 7处, 使滤前介质腔 Q与在进行反清 洗的过滤单元之间的切断效果更好; 如图 5、 图 5-1所示, 弹簧 25顶在管嘴 112的凸台上, 管嘴 112在弹簧 25的作用下紧贴在某个腔体出口 7处; 或者, 管嘴 112紧贴在 N个腔体出 口 7所在的器体 1内壁的一个环面上,使排污装置 10的旋转更加稳定;使器体 1的滤前介质 腔 Q与在进行反清洗的过滤单元之间的切断效果更好; 如图 4、 图 5、 图 6、 图 4-1、 图 5-1、 图 6-1所示, 排污装置 10带动吸污口 11处的管嘴 112在 N个腔体出口 7所在的器体 1内壁 的一个环面上进行间歇式移动时由于管嘴 112在吸污口 11上有一定的伸縮距离,减少甚至避 免了排污装置 10在大直径的器体 1内旋转时,排污装置 10上的吸污口 11与器体 1内壁之间 的卡滞现象。
对过滤单元 2中的滤芯 20的检修过程:过滤器工作一段时间,被滤芯 20截留的无法通 过其反清洗功能清洗掉的粘性、 油性杂质增多阻塞介质流通; 或者, 滤芯或滤芯上的部件损 坏, 需要对滤芯进行人工清洗或者检修。 如图 1、 图 7-1所示, 过滤器停机, 将器体 1内的 供输介质排放,拆卸单元进口 18与出接口 6之间及单元出口 19与进接口 8之间的连接部件; 如图 7所示, 过滤器无需停机, 关闭要检修滤芯 20的过滤单元 2的单元进口 18与出接口 6 之间及单元出口 19与进接口 8之间的切断阀 22, 拆卸切断阀 22与单元进口 18之间和切 断阀 22与单元出口 19之间的连接部件; 如图 1、 图 7、 图 7-1、 图 13、 图 14所示, 本发明 中的连接部件选用卡箍, 松开螺栓 3003, 拆下卡箍 3001、密封圈 3002, 拿下过滤单元 2, 在 单元座 21上卸下滤芯 20, 对滤芯 20进行清洗和检修, 检修结束后将滤芯 20重新安装在单 元座 21上, 再将过滤单元 2重新安装在器体 1上; 如图 1、 图 7、 图 7-1所示, 对器体 1上 的 N个过滤单元 2中的滤芯 20逐一检修并重新安装在器体 1上, 完成过滤器的过滤单元中 滤芯 20的检修。 如图 7所示, 当本发明装置过滤输送的介质压力较高时 (例如 2.5 MPa), 检修后的过滤单元 2重新安装在器体 1后, 连接该过滤单元 2与其它过滤单元 2之间的恒压 管路 26, 打开恒压管路 26上的管路阀 27, 让其它过滤单元 2中的带压介质进入新安装 在器体 1上的过滤单元 2中, 使该过滤单元 2中的压力与器体 1中的压力平衡, 就可以轻松 的旋转切断阀 22上的手轮开启切断阀 22,完成该过滤单元中滤芯 20的检修。按上述方法 将器体 1上的 N个过滤单元 2中的滤芯 20逐一检修并重新安装在器体 1上, 完成整个过滤 器滤芯 20的检修。如图 7所示,在需要连续供输介质并且介质供输流量有一定要求的供输系 统中,在检修滤芯 20时将器体外侧多增加的一个备用过滤单元投入使用。如图 1、图 7所示, 在检修滤芯 20的过程中所产生的气体通过器体 1上端的排气阀 28排出器体外。 如图 7-1所 示, 在检修滤芯 20的过程中所产生的气体通过过滤单元 2上端的排气阀 28排出器体外。 如 图 7、 图 8所示, 本发明中切断阀 22采用创新的角式截止阀, 旋转手轮, 阀杆 2202旋转带 动阀瓣 2205向阀座 2203移动关闭切断阀 22,器体 1内介质的压力作用在阀瓣 2205的左侧, 使阀瓣 2205与阀座 2203之间密封效果更好。
本发明过滤单元中滤芯可以选用能够进行反清洗的各种形式的单体结构滤芯或组合式 结构滤芯; 本发明中, 过滤单元 2在器体 1外侧, 可以做单排、 双排或多排设计, 以满足本 发明在各种过滤介质流量下体积最小化的设计要求, 当过滤单元为双排以上时, 出接口 6、 腔体出口 7、 进接口 8、 腔体进口 9相对应地进行双排、 多排设计; 排污装置 10上的吸污口 11也相对应地进行双吸污口 11、 多吸污口 11配套设计。 本领域技术人员还可以根据本发明 构思作出各种变化的实施方式。
由于本发明结构简单、 运行可靠、 维修方便、 适用范围更广, 完成了本发明的目的。
