本发明可清 滤器的工作过程如下:
过滤单元阀体 21上的隔膜阀口 28和排污隔膜阀口 31 ®1过液压源分配器及液压管路分 别将其阀口处隔膜片(排污口隔膜片 23、 入口隔膜片 26)膜腔内充压或泄压来实¾ (寸应阀口的 关闭和开启, 液压源分配器的泄压管路与排污管线 5相连。 当被过滤介质在管线自身压力下, 由过滤器入口 1流入, 经粗滤网 7粗滤后, 进入入口管线 3, 经分路管线上的入口截阀 10和过 滤单元阀体 21上的单元介质入口 25、 隔膜阀口 28进入阀体 21。 在经过隔膜阀口 28时, 入口 隔膜片 26在介质的压力作用下克服膜腔内弹簧力反弹打开隔膜阀口 28, 被过滤介质进入阀体, 当通过旋 道 24时形成旋 入过滤单元壳体 16与单柱式反冲洗喷管 13上的盘片柱 14之 间, 此赚压源分配器通过狐管路将排污口隔膜片 23膜腔内充压, 排污口隔膜片 23在压力 的作用下将排污隔膜阀口 31堵住。旋流的介质将其中大颗粒杂质靠其旋流离心力甩向过滤单元 壳体 16内壁上, 形成第一道旋流分离; 被过滤介质在通过设有弹簧助力的压紧套 17压紧的盘 片柱 14时, 其中大于盘片沟槽的杂质被阻挡¾ ^片柱 14的表面, 形成二次表面拦截过滤; 小 于盘片沟槽的杂质和 ¾1滤的介质一起进入盘片沟槽, 并在沟槽内相互碰撞凝聚, 再次被拦截, 形成深层过滤。嫩滤的介质在通 种形式过滤后进入盘片柱 14内, 并在压力作用下将单柱 式反冲洗喷管 13上流通孔 18处的止回片 19推开, 进入单柱式反冲洗喷管 13内, 再经单元介 质出口 22流入出口管线 9, 再进入供输管线中, 完成过滤过程。 当过滤器工作一定时间后, 各 过滤单元盘片柱 14经表面和深层过滤后形成杂质滤饼 ffiS , 入口管线 3和出口管线 9之间 出现压力差。 此时, 电控装置发出指令, 通过液压源分配器和液压管路, 使各过滤单 ¾¾—分 别进行反清洗排污。
过滤单元反清洗时, 在电控體和压力源分配器的指挥下, 通液压管路将过滤单元入口 隔膜片 26膜腔内力口压, 入口隔膜片 26移动将隔膜阀口 28关闭, 同时排污口隔膜片 23膜腔泄 压, 过滤单元内介质的压力克■莫腔内弹簧力推开隔膜片, 使排污隔膜阀口 31打开。 此时, 出 口管线 9中的被其它过滤单元过滤后的介质或其它压力源的介质反向经被反清洗过滤单元的单 元介质出口 22流入其单柱式反冲洗喷管腔内, 由于介质压力的作用, 止回片 19将流通孔 18堵 住, 介质只會 切向喷孔 20喷向盘片柱 14。 由于介质是切向喷出, 所以形成喷射旋流, 同时由 于排污隔膜阀口 31的开启,使过滤单元壳体 16和盘片柱 14之间压力小于反冲洗喷管腔内的压 力。故此, 压紧套 17在过滤单元壳体 16和盘片柱 14之间压力与反冲洗喷管腔内压力的压差力 作用下克服弹簧力被向上推移, 松开被压紧的盘片柱 14, 松散的盘片在喷射旋流的作用下套在 单柱式反冲洗喷管 13上高速旋转, 盘片沟槽内夹带的杂质滤饼以 M片柱 14表面的杂质一起 冲洗掉, 并与过滤单元壳体 16内壁上的杂质同时顺排污口排出。 一个过滤单元反清洗结束后, 电控装置发出指令, 通过液压源分配器和液压管路, 使其自动恢复过滤状态, 同时又使各过滤 单通一分别进行反清洗排污, 每个过滤单元反清洗全部结束后, 过滤器整纖入正常过滤状 态。
过滤单元反清洗时, 在电控 ¾S和压力源分配器的指挥下, 液压管路将过滤单元入口 隔膜片 26膜腔内加压, 入口隔膜片 26移动将隔膜阀口 28关闭, 同时排污口隔膜片 23膜腔泄 压, 过滤单元内介质的压力克■莫腔内弹簧力推开隔膜片, 使排污隔膜阀口 31打开。 此时, 由 于本发明带有备用过滤单元, 反清洗时电控装置发出指令, 电磁阀 6动作, 液压源分配器 使其自动投入工作, 替代了反清洗状态的过滤单元的工作, 致使供输介质的压力和流量保持不 变, 过滤器整机反清洗结束后, 备用过滤单元停止工作; 在检修时, 将备用过滤单元投入运行 后, 关闭要检修的过滤单元的进、 出口截阀对其进行检修, 供输介质的压力和流量保持不变, 过滤系统正常连续工作。
本发明结构简单, 设计合理, 检修和反清洗时无压力和流量损失, 是一种理想的 可清 猶滤器。
本发明过滤器中的过滤单元结构, 除了可以用于盘片式(或叠片式)管道自动清洗过滤器 外; 还可以通过阀门换向控制, 使只有一个过滤单元的过滤器或多个过滤单元过滤器实现手动 或半自动反清洗。
