具体实施方式
以下基于实施例对本申请进行描述，但是本申请并不仅仅限于这些实施例。
本申请公开了一种过滤结构，提高了液体过滤过程中的安全性；本申请还提供了一种过滤装置。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1-图4所示，图1为本申请提供的过滤装置的主视图；图2为本申请提供的过滤装置中过滤组件的布置位置示意图；图3为过滤结构的第一布置结构剖视图；图4为滤网的结构示意图。
本实施例提供一种过滤结构1，包括上盖11和底座12，二者之间围成腔室13；腔室13内具有铺装布置的过滤组件，过滤组件的过滤方向由上盖11向底座12方向布置，过滤组件靠近上盖11的一侧具有平面结构的导流端面。腔室13由上盖11结构和底座12结构盖装配合围成，其内设置过滤组件，过滤组件具有平面铺装结构，其上可铺装布置滤膜，在腔室13内形成沿上盖11经过滤组件向底座12方向的过滤方向，将液体经过滤组件过滤，过滤组件具有平面结构的导流端面，液体经上盖11流入，在过滤组件的导流端面经其平面结构流至过滤组件的表面，从而获得较大的过滤面积，由过滤组件的表面进行整面过滤，随滤渣在滤膜上积累，仍能获得较好的过滤效果，降低过滤面积减少造成的过滤失效情况。
可以理解的，过滤组件的导流端面设置为平面结构，该平面结构可以设置为平面表面，也可以设置为具有小角度的斜面表面、曲面表面、凹面表面、凸面表面、锥面表面等结构，用于将液体经过滤组件的导流端面，沿其周向进行 液体的铺开，从而实现在过滤组件的整个表面进行液体过滤。
在本案一具体实施例中，过滤组件包括滤网(15、16)，滤网(15、16)厚度方向的一侧对滤膜14进行支撑。液体由上盖11通入，顺序经过滤膜14和滤网(15、16)后进入底座12。
腔室13为盘状腔室，上盖11的中部设置进液口，底座的中部设置出液口；
进液口内设置伸入至腔室13内的进液接头17，进液接头17沿周向布置多个朝向腔室13的径向布置的分液孔171。
腔室13采用盘状腔室，进液口设于上盖11的中部，为避免进液直接冲击滤膜14，在进液口设置进液接头17，进液接头17外部用于连接进液管路，进液接头17的内部设置多个分液孔171，进液接头17伸入上盖11的内部，进液接头17采用圆柱结构，其内开设进液通道，分液孔171分布于进液接头17的周向，从而使得进液沿腔室13的径向喷出，避免进液直接冲击滤膜14，提高进液分布均匀性。
本实施例中，滤网(15、16)包括上层滤网15和下层滤网16，上层滤网15包括并行铺设的多条支撑条，相邻的支撑条之间围成过液间隙；下层滤网16为分布有多个排液孔的板状滤网。
过滤组件由平板状的滤网(15、16)和铺设在滤网(15、16)上的滤膜14组成。滤膜14是过滤装置的核心部件，其选用的主要参数包括滤膜材料、滤膜外径、滤膜孔径等。本实施例中，滤膜14为由醋酸纤维或混合纤维材料制成。适应不同规格的过滤组件，滤膜外径可采用47mm、50mm、100mm、150mm等不同规格，还可以按照不同的过滤需求定制不同外径规格。滤膜孔径和过滤的目的有关，本实施例可采用5um、1um、0.45um、0.22um等多种孔径规格。上述参数与过滤速度、滤膜强度高度相关，滤膜外径越大、过滤孔径越大，过滤速度越快。滤膜参数的选择需要根据实际的应用场景而定。
平板状的滤网(15、16)起到支撑滤膜的作用，本实施例中，滤网(15、16)上分布有孔隙，过滤后的液体会从平板的孔隙中流走，同样，孔隙分布和面积大小也会影响到过滤速度。考虑滤膜受到液体压力朝向滤网方向进行挤压，将滤网设置包括上层滤网15和下层滤网16双层结构，上层滤网15采用支撑条并行布置的方式，相邻的支撑条之间围成过液间隙，下层滤网16用于对过滤后的液体的排出。
优选地，支撑条包括由腔室13的中部向外并行铺设，呈同心圆结构布置的多条环形支撑条。适应腔室13的盘状结构，将滤网(15、16)设置为盘状滤网，对应地滤膜14采用盘状滤膜，将支撑条设置为同心圆布置的多条环形支撑条，提高对滤膜的支撑稳定性，保证过滤过程中的支撑强度，并在相邻的环形支撑条之间形成环形过液间隙，其与下层滤网配合，保证了滤膜的过滤能力。
如图5-图6所示，图5为本申请提供的过滤结构的第二布置结构剖视图；图6为图5中过滤结构的底座结构示意图。
在本申请一具体实施例中，上盖11和底座12之间压装有环形密封圈，液体由进液接头17上的多个分液孔171进入到腔室13，经过滤组件进入到底座12的出液口18流出，设置环形密封圈于上盖11和底座12的外周，避免过滤液体由二者之间流出。
环形密封圈包括压装于过滤组件上端面的内层密封圈51，和压装于内层密封圈外圈的外层密封圈52；
内层密封圈51对过滤组件的周向边缘进行隔液密封，外层密封圈52对上盖11和底座12之间进行隔液密封。
正常工作过程中，液体穿过过滤组件的上端流入下端，完成液体过滤。内层密封圈51压装在过滤组件的上端面边缘，避免液体由过滤组件的边缘泄露，设置内层密封圈51，保证滤液经过滤组件流出。过滤组件超过过滤负荷，液体经内层密封圈51泄露后，应避免液体流入设备内部，设置外层密封圈52直接压紧于上盖11和底座12之间，避免液体进入设备内部，造成内部设备浸入损坏。
极端情况下，在内层密封圈51发生泄露，且过滤组件堵塞后，仍有液体输入造成外层密封圈52泄露，为了避免设备失效，设置保护结构。
本实施例中，底座12上设置有溢流通道53，溢流通道53的入口位于内层密封圈51和外层密封圈52之间，溢流通道53连通底座12的出液口18；溢流通道53包括环绕底座12周向的环形部531和多个分流槽532。
具体地，溢流通道53包括环绕底座12周向的环形部531，以及由环形部531连通至底座12上表面的多个分流槽532，经内层密封圈51泄露的液体进入环形部531，并由多个分流槽532进入腔室13的下部，形成直接连通腔室13的上部至下部的溢流通道，从而保证滤液安全。
内层密封圈51压装在过滤组件的上端面，优选的将滤膜14进行压紧固定，该结构中，上盖11上布置内层密封圈51的上安装槽，其在底座上固定，液体只能通过该滤膜14流出，以此对进行过滤。外层密封圈51直径大于滤膜14外径，只对上盖11和底座12进行密封。该结构中，底座12的上表面设置外层密封圈52的下安装槽，外层密封圈52落于下安装槽内。
通过内层密封圈51和外层密封圈52的压缩量来控制内外圈密封强度，优选地，内层密封圈51密封效果小于外层密封圈52的密封效果。
同时，在内层密封圈51和外层密封圈52之间的平面结构上设计溢流通道53，当内层密封失效的时候，液体可以从溢流通道53流走，这样就可以保护滤膜14不至于被冲破，同时由于外层密封圈52的保护，不会造成仪器溢流。
如图7-图8所示，图7为本申请提供的过滤结构中泄压阀结构示意图；图8为图7中泄压阀的剖面结构示意图。
本实施例中，上盖11上还布置有泄压阀8，泄压阀8内具有沿第一方向布置，并连通腔室13的泄压通道80；
泄压阀8内设有上下滑移布置，与泄压通道80封堵配合的封堵装置。
泄压阀8由上盖11上伸出，泄压通道80的第一方向即为泄压阀8插装于上盖11厚度方向的装入方向。考虑泄压阀8会增加上盖的整体高度，泄压阀8装入上盖的方向设为第一方向，该第一方向为泄压阀8装入端的轴向，为降低高度，可将泄压阀8伸出上盖的一端变向为与第一方向垂直或呈一定角度的第二方向，使得泄压阀8构成由主体结构和装入端组成的两部分。基于泄压阀8的主体结构和装入端的两部分结构，泄压通道布置于泄压阀8的装入端，封堵装置布置于泄压阀8的主体结构内。本实施例一优选结构中，第一方向为泄压阀8的轴向，即将泄压通道80和封堵装置沿泄压阀8的轴向布置。
本实施例中，封堵装置包括布置在泄压阀内的滑移通道，滑动布置于滑移通道内的弹簧座84；
弹簧座84的第一端与泄压通道80封堵配合，弹簧座84的第二端布置推动其压紧于泄压通道80上的弹性复位装置87；
泄压阀8的外圈还布置有拖动弹簧座84滑移的滑移拨杆86。
过滤装置工作时，液体通过泵注入到过滤器的腔室13中，当腔室13体内未注满液体时，会产生压缩气体，即使泵停止运作，腔室13内仍然有压力气 体，常规结构中，一般采用带密封圈的螺丝进行泄压，螺丝锁紧时将腔室密封，螺丝松开时将腔室泄压，泄压过程繁琐费时间，提高了人工成本。
通过设置泄压阀8，用来平衡过滤装置压力腔体内部和外部的大气压力，主要包括阀体81、外密封圈82、内密封圈83、弹簧座84、弹簧87、弹簧调节螺丝85、滑移拨杆86。
阀体81下端伸出安装头，安装头与阀体81连接位置设置下密封槽820，外密封圈82套入安装头并落在下密封槽820内。阀体1内设置滑移通道，弹簧座84滑动布置在滑移通道内，阀体81与弹簧座84封堵配合的上端，设置上密封槽830，泄压通道80伸入上密封槽，使得上密封槽830呈环装结构，内密封圈83套入上密封槽830内。
弹簧座84在阀体81内，并布置于同轴布置滑移通道内，弹簧座84与内密封圈83相抵接。
弹簧座84背离泄压通道80的一侧设置弹簧安装槽，弹性复位装置87优选采用压缩弹簧87，压缩弹簧87设置在弹簧座84的弹簧安装槽内，阀体81的顶部设置开口，通过弹簧调节螺丝85装入阀体81的顶部开口，并通过螺纹安装配合。弹簧调节螺丝85和弹簧座84对压缩弹簧87的两端进行压紧、抵接，滑移拨杆86与弹簧做84通过螺纹副配合。
泄压阀8与上盖11通过螺纹副配合，并通过外密封圈82实现密封；阀体81内设置有一轴向的泄压通道80，使得腔室13与弹簧座84相连通；当手动提起滑移拨杆86时，弹簧座84克服压缩弹簧的弹簧力向上运动，使弹簧座84与内密封圈83分离开，此时腔室13与大气相连通，起到泄压作用；当手松开滑移拨杆86时，则弹簧座84在弹簧力作用下向下运动，并压紧内密封圈83使腔室13与大气断开，起到密封作用，同时压缩弹簧87的弹簧力可根据系统需要进行调节，当腔室87内压力过高时，推动弹簧座84向上运动，起到安全阀作用。
基于上述实施例中提供的过滤结构，本申请还提供了一种过滤装置，包括动力源，送液管路，布置于送液管路上的过滤结构1，该过滤结构为如上任一项所述的过滤结构；
还包括过滤装置箱体，其具有箱体盖板2和箱体主体3，箱体主体3的顶部用于安装过滤结构1，箱体主体3的内部用于布置动力源。
由于该过滤装置采用了上述实施例的过滤结构，所以该过滤装置由过滤结构带来的有益效果请参考上述实施例。
过滤结构采用盘状结构的滤膜14进行轴向过滤，由上盖11和底座12围成的液体腔室13可以获得较小的轴向占用空间。设置过滤装置具有过滤装置箱体，在箱体主体3顶部布置安装过滤结构1的多个安装孔，本实施例优选采用2个并行的过滤结构1，通过螺钉可拆卸固装于箱体主体3顶部，从而可实现对多个过滤结构的安装。
通过设置2个过滤结构1，可在箱体主体3内布置形成两套过滤系统，可以同时使用，也可以独立使用，满足不同过滤通量要求。
箱体主体3的内部用于安装布置动力源，通过箱体盖板2对箱体主体3进行盖装，实现对过滤装置便携携带和防护。
本实施例中，动力源包括蠕动泵4，蠕动泵4包括进液端和出液端，蠕动泵的出液端连通至过滤结构1的进液口。动力源还包括供电组件等，也可以选用真空泵、蠕动泵、隔膜泵等。蠕动泵4设于过滤结构1的前端，因此能够提供给过滤结构1较大的液流正向压力，结合过滤结构采用平铺结构的滤膜14和滤网(15、16)支撑结构，可有效提高液体过滤速率，保证过滤效果。
如图9所示，图9为本申请提供的过滤装置的系统布置图。
蠕动泵4的前端还设置对液体中杂质进行去除的粗滤器5，粗滤器5与蠕动泵4的进液端连通。考虑到液体会面临很浑浊的工况，在蠕动泵4前端需要对液体进行粗滤。选择大孔径的滤膜对大的杂质进行粗滤过滤，防止破坏过滤系统。
本实施例中，送液管路6上还设置对泵液压力和/或流量进行监测的压力流量监控装置7；
还包括控制装置，其在泵液压力大于第一压力，并小于第二压力时，调节蠕动泵工作于高速区间；并在泵液压力大于第二压力，调节蠕动泵工作于低速区间；以及在泵液压力小于第一压力，提示系统状态异常。
过滤装置进行液体过滤时，送液管路6顺序连通液源、粗滤器5、动力源以及过滤结构1等进行液体过滤，液体由动力源驱动通过滤膜进行过滤，本实施例优选动力源采用蠕动泵。
压力流量监控装置7置于管路系统中，对系统压力或流量进行实时监控并 反馈，蠕动泵4工作过程中，随着滤膜上滤渣的堆积，送液管路6内液体压力流量均发生变化，通过对管路压力数据进行实时测量，设置第一压力为P1，第二压力为P2，管路压力为P，当P1<P<P2时，滤膜具有较高的过滤效率，此时控制蠕动泵高速工作，高速过滤；P>P2时，管路内的压力变大，说明滤膜的过滤能力降低，此时控制蠕动泵减速工作，低速过滤，防止滤膜破损；P<P1时，系统状态异常，停机并报警。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本申请。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本申请的精神或范围的情况下，在其它实施例中实现。因此，本申请将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
