Description

一种物料无热干化系统、压滤机控制方法及压滤机 技术领域
本申请涉及压滤设备领域，尤其涉及一种物料无热干化系统、压滤机控制方法及压滤机。
背景技术
压滤机是实现固液分离的设备，广泛使用于化工、石油、媒矿、制药、食品、市政等行业。现有的压滤机一般都是在机架的前/后端设置止推板，后/前端设置压紧板，在止推板与压紧板之间设置一组滤板，滤板通过其左右两侧手柄与机架主梁上的导轨连接，在压滤机工作过程中，油缸组推动压紧板使滤板组之间靠紧，压滤完成后在拉板小车拉动作用下滤板之间分离，如此往复运动实现固液的分离。现有的压滤机在工作过程中油缸压力不能智能调节，造成这种加压方法使滤板组件的边框受力在每个工作周期都会经历大小循环的变化过程，容易造成边框疲劳破坏，也限制了滤室的最大工作压力不能太高。
基于以上问题，有必要研发出新的压滤机，以稳定压滤机滤板组件内部工作压力。
发明内容
为了实现压滤机滤板组件内部衡压、降低滤板组件疲劳破坏的几率，本申请提供了一种物料无热干化系统、压滤机控制方法及压滤机。
第一方面,本申请提供的一种物料无热干化系统，包括：压榨装置，包括导向装置和沿导向装置滑移的滤板组件；进料装置，包括与滤板组件连接的进料管和进水管；驱动装置，包括驱动压榨装置运动的驱动机构；衡压装置，包括电磁阀门、与所述进料管连接的进料压力传感器和与所述进水管连接的压榨压力传感器；其中，当所述滤板组件滑移至预设位置时驱动机构停止工作，对应电磁阀门进行得失电动作，所述衡压装置切换进入衡压模式。
结合第一方面，进一步的方案，所述驱动机构包括滑动组件和与所述滑动组件连接的支撑座,所述支撑座连接有第一液压缸、第二液压缸和第三液压缸；其中，所述第一液压缸的轴线和所述第三液压缸的轴线分别与滑动组件的移动方向平行，所述第一液压缸和所述第三液压缸用于驱动所述支撑座沿所述滑动组件移动方向移动；所述第二液压缸设置于所述滑动组件上用于驱动所述支撑座沿与所述滑动组件移动方向相垂直的方向移动。
通过采用上述技术方案，压滤机压紧时，初期不需要过大的压力，所以第一液压缸为快速推进液压缸，用油量小,不需要提供过大的推力，但能够实现快速推进，第一液压缸可以带动第三液压缸沿着滑动组件移动方向快速前后移动，缩短了第三液压缸的行程，减少压滤机压紧前液压油的使用。本方案可以设置多个第三液压缸配合，能够为压滤机提供足够的工作压力。第二液压缸带动第三液压缸在与所述滑动组件移动方向相垂直的方向升降，可以调节第三液压缸的工作位置以适应不同的工作需求。
结合第一方面，进一步的方案，该系统还包括衡压装置和与进料管、进水管，所述衡压装置包括：与所述进料管连接的进料压力传感器、与所述进水管连接的压榨压力传感器和为所述第三液压缸提供液压的液压站，所述第三液压缸连接比例压力阀。此外，所述衡压装置还包括与所述进料压力传感器、压榨压力传感器和所述比例压力阀均连接的控制器，所述控制器用于在脱水工作时通过控制比例压力阀调节所述第三液压缸的压力。

通过采用上述技术方案，两个传感器的压力信号经控制器比较后，把压力大的一个值作为滤室工作压力P 入，并由控制器依据P 入输出一个压力信号P 出，该输出信号控制比例压力阀的溢流压力。当油泵向第三液压缸供油时，确保了第三液压缸工作压强＝滤室工作压强*系数+预紧压强，如第三液压缸的压强大于KP 入+P 0，则比例压力阀溢流，使第三液压缸的压强始终等于KP 入+P 0。如第三液压缸压强低于KP 入+P 0，则启动液压油泵，向第三液压缸补压，直到第三液压缸压强等于KP 入+P 0。既能有效避免滤板自动打开造成漏料，又不至于使滤板边框在滤室无压力时承受过大的压强。

实施例一：
请参阅图1至图4所示，本申请物料无热干化系统1实施例一的结构示意图。物料无热干化系统1包括压榨装置、进料装置、开模装置、衡压装置7、回水装置4。压榨装置包括导轨151和沿导轨151滑移的滤板组件，
进料装置包括与滤板198组件连接的进料管51和进水管61。开模装置包括驱动压榨装置运动的驱动机构72，衡压装置7包括电磁阀门、与所述进料管51连接的进料压力传感器711和与所述进水管61连接的压榨压力传感器712。回水装置4包括用于对压榨装置流出的残液进行导流的接水盘组件41。当所述滤板198组件滑移至预设位置时驱动机构72停止工作，对应电磁阀门进行得失电动作，所述衡压装置7切换进入衡压模式。
请参阅图1所示，一种压滤机物料无热干化系统1，包括驱动机构72，驱动机构72包括滑动组件15和与所述滑动组件15连接的支撑座11,支撑座11连接有第一液压缸12、第二液压缸16和第三液压缸13。第一液压缸12的缸体固定在基座14上，第一液压缸12的活塞杆131与滑动组件15连接，本实施例的第一液压缸12为快速推进液压缸，不需要提供过大的推力，但能够实现快速推进。滑动组件15包括导轨151和滑块，导轨151沿第一液压缸12的活塞杆131的伸缩方向延伸。本实施例中，导轨151设置于压滤机的侧板17的上表面。可选地，在左侧板和右侧板上均设有导轨151，为液压缸支撑座11的前后移动提供稳定的导向。导轨151还可作为压滤机的滤板组件的导轨151使用。滑块可滑动的设置于导轨151上。第一液压缸12的活塞杆131连接滑块，第一液压缸12带动滑块沿导轨151滑动。
第二液压缸16设置于滑块的上表面，第二液压缸16的活塞杆131能够沿与第一液压缸12伸缩方向垂直的方向伸缩。液压缸支撑座11连接第二液压缸16，第二液压缸16能够带动支撑座11进行升降。液压缸支撑座11与基座14相互平行设置。第一液压缸12通过滑块能够带动液压缸支撑座11前后移动，第二液 压缸16能够带动液压缸支撑座11进行升降。
第三液压缸13设置于液压缸支撑座11上。本实施例中，第三液压缸13的缸体穿过支撑座11安装在支撑座11中。第三液压缸13的活塞杆131的伸缩方向与第一液压缸12的活塞杆131伸缩方向相同，第三液压缸13连接压滤机的压紧板10，在物料无热干化系统1远离基座14的一端设有止推板110，滤板组件设置于压紧板10和止推板110之间。
第一液压缸12的轴线和第三液压缸13的轴线分别与滑动组件15的移动方向平行，第一液压缸12和所述第三液压缸13用于驱动所述支撑座11沿所述滑动组件15移动方向移动；第二液压缸16用于驱动所述支撑座11沿与滑动组件15移动方向相垂直的方向移动。
基座14包括隔板141和隔板141之间形成的通孔142，第三液压缸13的缸体上固定有顶杆133，顶杆133设置于第三液压缸13的远离压紧板10的一侧。顶杆133能够插入基座14的通孔142内。本实施例的驱动结构，在压滤机压紧过程中，初期不需要过大的压力，第一液压缸12的活塞杆131伸出，推动滑动组件15、液压缸支撑座11、第三液压缸13、顶杆133和压紧板10快速前进，达到预设位置后停止，顶杆133移出基座14的通孔142。第二液压缸16的活塞杆131伸出，推动支撑座11、第三液压缸13、顶杆133和压紧板10上升预设高度，顶杆133的轴线与对应的基座14的水平隔板141基本平齐。第三液压缸13的活塞杆131伸出，以较大的推力推动压紧板10前进，实现滤板组件的压紧。第三液压缸13推动压紧板10前进时，顶杆133抵住基座14的隔板141，为第三液压缸13提供支撑力。压滤机的滤板组件需要分离时，第三液压缸13的活塞杆131收回，带动压紧板10后退。第二液压缸16的活塞杆131收回，带动液压缸支撑座11、第三液压缸13、顶杆133和压紧板10下降，顶杆133下降至轴线对应基座14的通孔142的轴线位置。第一液压缸12的活塞杆131收回，带动滑块、支撑座11、第三液压缸13、顶杆133和压紧板10后退，顶杆133插入基座14的通孔142中，完成复位。
第三液压缸13和顶杆133的数量均为多个。每个第三液压缸13的缸体上设置一个顶杆133。多个第三液压缸13以矩形阵列的形式设置在液压缸支撑座11上。多个第三液压缸13配合共同为压紧板10提供推力，以增大压滤机的工作压力。通过增加第三液压缸13的数量增大压滤机的工作压力，而不是通过增大单个第三液压缸13的工作压力以提高压滤机的工作压力，可以降低第三液压缸13对密封件的损伤，提高压力机的寿命。根据本申请一个可选的技术方案，顶杆133为空心结构，以减轻顶杆133的重量。
请参阅图2所示，滤板组件包括大小、形状一致的料模19和水模18，所述料模19和水模18一比一交替设置，进料管51与料模19连接，进水管61与水模18连接。物料无热干化系统1包括与支撑座11平行设置的止推板110，滤板组件位于止推板110和支撑座11之间，水模18的外端面设有隔膜胶皮。
请参阅图3所示，料模19设有进料口193，料膜还设有出料机构，出料机构包括设置在料膜隔板141内的浆料通道195、浆料通道195分别在料膜隔板141的两面上形成的出料口194、设置在出料口194的翻盖191，翻盖191为弹性材质，翻盖191覆盖出料口194。在料模19和水模18之间形成滤室192，浆料通过进料口193进入浆料通道195，并通过出料口194冲开翻盖191进入到滤室192，在滤室192内浆料被初步压滤过滤部分水分，然后水模18注水，通过水模18的逐步膨胀对滤室192进一步压滤过滤水分，最终泥浆料形成料饼。
请参阅图4所示，料模19包括滤板198、滤板边框；滤板边框包括设置在滤板198边缘并且厚度大于滤板198的外框197、设置在外框197体内围面上以及滤板198表面上的内框196，内框196的厚度由外至内逐渐减小。内框196至少一部分为合成树脂类浇注体，料模的其余部分为刚性金属体。
实施例二：
请参阅图5所示，本申请物料无热干化系统1实施例二的结构示意图。与实施例一不同的是，本实施例只设有一组液压缸，也就是第三液压缸13。本实施例的物料无热干化系统1包括基座14、两个间隔开并且固定在基座14左右两侧的侧板17、多个第三液压缸13以及压紧板10。第三液压缸13包括油缸外筒、 安装在油缸外筒上的活塞杆131，基座14上对应每个油缸外筒均设有多个固定结构132，固定结构132和油缸外筒的后端面固定连接。两个机架2的侧板17之间安装有支撑座11，支撑座11具有多个套接在油缸外筒前端上的前安装孔，活塞杆131穿过前安装孔并固定连接所述压紧板10。基座14上设有后固定板，支撑座11和后固定板之间设有多个固定连接两者的连接结构。
本实施例所有的油缸均为主油缸，从而提高压紧板10的挤压性能，并且通过支撑座11、机架侧板17、后固定板以及基座14共同分摊油缸的负载重量，减轻了油缸座的负担，此外，支撑座11、基座14形成了对油缸的两处安装位置，使得油缸的安装牢固性更为可靠。
实施例三：
请参阅图6所示，公开了一种衡压装置7结构，包括厢式压滤机、与其配套连接的主缸722也即第三液压缸13、滤板组件、进料管51和进水管61、为主缸722提供液压的液压站73，进料管51设置进料压力传感器711，压榨液管道设置压榨压力传感器712，液压站73的出口连接比例压力阀730，厢式压滤机的外部设有一控制器71，进料压力传感器711、压榨压力传感器712和比例压力阀730均与控制器71相连接。根据厢式压滤机的工作特性，进料和压榨不会同时进行，但进料压力和压榨压力都会作用在滤室192上，因此本实施例分别在进料管51和压榨液管道上分别安装压力传感器，测量进料管51和压榨液管道的压力，可以得出滤室192工作压力的大小，两个传感器的压力信号经控制器71比较后，把压力大的一个值作为滤室192工作压力P 入，并按下式控制比例压力阀730的输出压力P 出，P 出＝KP 入+P 0，式中k为滤板198面积与主缸722截面积之比值,也可以取滤室192与主缸722截面积之比，P 0为预紧压强，P 入为滤室192工作压强，P 出为主缸722工作压强，确保了主缸722工作压强＝滤室192工作压强*系数+预紧压强，工作时，当油泵向主缸722供油时，确保了主缸722工作压强＝滤室192工作压强*系数+预紧压强，如主缸722的压强大于KP 入+P 0，则比例压力阀730溢流，使主缸722的压强始终等于KP 入+P 0。如主缸722压强低于KP 入+P 0，则启动液压油泵，向主缸722补压，直到主缸722压强等于KP 入+P 0。既能有效避免滤板198自动打开造成漏料，又不至于使滤板边框在滤室192无压力时承受过大的压力。滤板198包括大小形状一致的料模19和水模18，料模19和水模18一比一交替设置，厢式压滤机的两侧在竖直方向上设有一对止推板110和压紧板10，止推板110与厢式压滤机的机体固定连接，压紧板10与主缸722固定连接，料模19和水模18位于止推板110和压紧板10之间。将滤室192设置为层叠三明治状，可以最大程度上利用工作空间，压滤更多的物料，工作效率更高，而止推板110为滤室192的限位板，防止滤室192往后移动，与主缸722固定连接的压紧板10为滤室192的制动板，负责对滤室192进行挤压。水模18的外端面设有隔膜胶皮。隔膜胶皮将滤饼和水模18隔离，防止滤渣进入到水模18中，堵塞水模18，造成水模18无法正常使用，更能使水模18方便清洗。
本实施例的工作原理如下：在压力脱水时，所述控制器71根据进料压力传感器711信息控制比例压力阀730，使得自始至终，第三液压缸13的液压满足以下关系：P 出＝KP 入+P 0，其中，P出为控制器71输出压力，也即第三液压缸13的工作压力，此时P 入取进料压力，P 0为预紧压力，K为比例系数。在挤压脱水时，当压力脱水达到设定条件后，从进水管61中输入压榨液，所述控制器71根据压榨压力传感器712信息控制比例压力阀730，使得自始至终，第三液压缸13的液压满足以下关系：P 出＝KP 入+P 0，其中，此时P 入取压榨压力。
本实施例的工作过程如下：
第一液压缸12工作，推动支撑座11向止推板110方向移动。第二液压缸16工作，推动支撑座11沿与所述滑动组件15移动方向相垂直的方向移动。第三液压缸13工作，推动支撑座11向止推板110方向移动。
合模：在料模19表面设置滤布后，止推板110、料模19、水模18、支撑座11紧密贴合实现合模。
压力脱水：物料从进料管51进入料模19，到达料模19和水模18形成的滤室192，此时进料管51压 力升高，进料压力传感器711将信息传送到控制器71，控制器71通过控制比例压力阀730，使第三液压缸13的压力随着提高，自始至终，第三液压缸13的液压满足以下关系：P 出＝KP 入+P 0，P 入取进料压力；
物料压滤后的水分从料模19和水模18的下部排出。
挤压脱水：压力脱水达到设定条件后，停止进料，从压榨液管道中输入压榨液到水模18，当压榨液管道中的压力升高时，压榨压力传感器712将信息传送到控制器71，控制器71通过控制比例压力阀730，使第三液压缸13的压力随着提高，自始至终，第三液压缸13的液压满足以下关系：P 出＝KP 入+P 0，P 入取压榨压力。压榨液推动水模18表面的隔膜胶皮，挤压滤饼，使滤饼中的残液继续排出。
开模及卸料：关闭压榨液管道，第三液压缸13返回，拉动支撑座11，打开料模19和水模18，将干燥的滤饼卸出，完成压滤过程。
实施例四：
请参阅图7和图8所示，本申请的一种压滤机结构示意图。压滤机包括底座3和底座3上固定的机架2，物料无热干化系统1固定在底座3和支架上。在机架2上还固定安装有进料主管5和与进料主管5连通的进料管51，进料管51与料模19的进料口193连通。
实施例五：
请参阅图9和图10所示，公开了压滤机的另一实施例。与实施例四不同的是，压滤机还包括回水装置4，回水装置4包括接水支架43和固定于接水支架43上的轨道44和驱动组件42，接水支架43底部安装有支脚45，接水盘组件41滑动连接于轨道44上通过伸缩组件与驱动组件42连接。接水盘组件41包括依次嵌套设置的多组接水盘，伸缩组件连接于所述多组接水盘中的至少两组接水盘之间，伸缩组件的伸缩运动带动接水盘组件41沿伸缩组件的伸缩方向调节接水盘之间的相对位置。伸缩组件包括多个伸缩单元，每个伸缩单元连接于所述至少两组接水盘之间。接水盘组件41中相邻接水盘的连接处设置有密封条。
伸缩组件为剪叉式伸缩组件，一端抵接于接水盘组件41的固定端，即接水盘组件41的最外层接水盘。伸缩组件的另一端抵接于接水盘组件41的活动端，即接水盘组件41的最内层接水盘。随着伸缩组件的伸缩运动，接水盘组件41的最内层接水盘朝着远离接水盘组件41的固定端的方向移动，从而使得接水盘组件41延展开。当伸缩组件处于伸展的过程中，每个伸缩单元逐渐被拉长，伸缩单元固定于两个接水盘上的固定点的距离被拉大，与此同步的，伸缩单元菱形外轮廓的另外两个随动点之间的距离被拉近，从而实现单个伸缩单元的伸展。同理，当伸缩组件处于收缩的过程中，每个伸缩单元逐渐被拉短，伸缩单元固定于两个接水盘上的固定点的距离被拉小，与此同步的，伸缩单元菱形外轮廓的另外两个随动点之间的距离被拉远，从而实现单个伸缩单元的收缩。
回水装置4还包括：驱动组件42，设置于所述底座3上，驱动组件42连接于所述接水盘组件41和/或所述伸缩组件，用于驱动接水盘组件41扩展和收缩。驱动组件42包括：电机，设置于所述底座3上；链轮，耦接于所述电机；轴承，所述链轮通过所述轴承耦接于所述电机；链条，设置于所述链轮，且所述链条连接于所述接水盘组件41和/或所述伸缩组件。
现有的压滤机接水翻板大多包括两组呈对称设置的翻板机构，在使用的过程中，当压滤机对待处理污泥进行压滤除水处理的过程中，接水翻板处于闭合的状态；而当压滤机除水处理完成后，通过旋转驱动组件42带动呈对称设置的翻板机构向下转动打开。这种设置状态的压滤机接水翻板存在诸多弊端，接水翻板打开时需要较高的作业空间，对压滤机回水装置4的安装布置带来了不利因素，容易导致安装不平或安装位置偏差而造成振动或噪音。旋转驱动组件42大多选用液压驱动源，在合模的过程中需要不断进行补压，一旦液压下降到低于一定阈值，接水翻板会随着液压下降而自动打开。不仅如此，由于接水翻板在翻板过程中需要较大的转动力，其旋转驱动组件42需要选用大功率的驱动装置，这无疑会对现场布置带来一定的负面影响。
本实施例通过嵌套设置的多组接水盘和伸缩组件实现回水装置4整体的伸缩，在压滤机的滤板198组 合模前，通过驱动机构72带动回水装置4伸展，向止推板110的方向滑动，到达预定位置后，进行压滤机的整体合模。直至压滤机完成合模压榨作业后，在压滤机开模之前，通过驱动机构72带动回水装置4收缩，向油缸座的方向滑动，直至到达回水装置4的预定收纳位置，然后进行压滤机的开模。
实施例六：
请参阅图11所示，公开了压滤机的又一实施例。与实施例五不同之处在于，还包括压榨主管6和与压榨主管6连通的进水管61，进水管61一端与压榨主管6连通另一端与水模18连通。相邻两个料模19之间安装有水模18，料模19上安装有滤布，滤布延伸到料模19两侧，隔膜的两侧壁设有隔膜，隔膜通过水压的作用下向外鼓起并挤压料模19上的待过滤介质。机架2同一侧边上安装有进料主管5和压榨主管6，进料主管5输送待过滤介质进入料模19内，压榨主管6用于输送水。每个料模19通过对应的进料管51与进料主管5连通，每个水模18通过对应的进水管61与压榨主管6连通。
实施例七:
与实施例六不同的是,本压滤机进料主管5与压榨主管6固定于机架2同一侧的侧板17上，进料主管5与压榨主管6上下布置，减少压滤机整体体积，从而减少压滤机占用面积。本结构进料主管5与压榨主管6直接固定于底座3上，减少了固定支架的同时也减少制作成本。无需现场制作，可直接随车发货。

进料：液压系统是否衡压完成，如未进入衡压完成状态系统无法执行进料操作；检测回料阀门是否关到位；检测接水板是否合到位；检测料罐液位是否满足进料条件。进料泵电机启动。
衡压控制：压力脱水，物料从进料管51进入料模19，到达料模19和水模18形成的滤室192，此时进料管51压力升高，进料压力传感器711将信息传送到控制器71，控制器71通过控制比例压力阀730，使第三液压缸13的压力随着提高，自始至终，第三液压缸13的液压满足以下关系：
P 出＝KP 入+P 0，P 入取进料压力，K为比例系数；
物料压滤后的水分从料模19和水模18的下部排出；
挤压脱水，压力脱水达到设定条件后，停止进料，从压榨液管道中输入压榨液到水模18，当压榨液管道中的压力升高时，压榨压力传感器712将信息传送到控制器71，控制器71通过控制比例压力阀730，使第三液压缸13的压力随着提高，自始至终，第三液压缸13的液压满足以下关系：P 出＝KP 入+P 0，P 入取压榨压力，K为比例系数；压榨液推动水模18表面的隔膜胶皮，挤压滤饼，使滤饼中的残液继续排出；
回水：高压回水阀门按工艺要求缓缓打开直至开到最大位置；当压榨压力降至系统允许值以下，隔膜泵启动；按系统设置时间进行回水计时，计时达到回水动作结束。高压回水阀门与隔膜泵按回水工艺状态进行启动。
