Description

一种高压水射流板带材喷砂除鳞清理装置、清理线及系统 技术领域
本发明涉及喷砂清理设备技术领域，具体涉及一种推拉式高压水射流板带材喷砂除鳞清理装置、水射流清理线及系统。
背景技术
现有去除宽板带材表面鳞皮的方法主要有：1、化学方法(即酸洗)；2、机械清理(主要为弯曲剥壳和摩擦清除)；3、抛丸喷砂法。上述化学方法会产生大量工业废水废气，对环境造成严重污染，并且生产效率较低。采用机械清理方法表面质量却不高，难以达到应用要求。采用抛丸喷砂处理则会产生粉尘污染，对工人身体造成危害，且功耗大。
随着金属带材高压水射流喷砂清理生产线在各地钢厂的应用，利用高压水射流喷砂除鳞技术去除板带材表面鳞皮的方法正在逐步取代以上化学、机械和抛丸工艺或方法，特别是通过金属带材高压水射流喷砂清理生产线生产的中、窄规格的板带材在表面质量、硬度等方面已接近甚至超过酸洗等工艺生产的中、窄规格板带材。另外，利用高压水射流喷砂除鳞技术生产的金属带材高压水射流喷砂清理生产线，不仅没有废酸废水废渣排放，绿色环保，而且生产效率高，运行成本低。
但是，由于高压水射流喷砂除鳞技术应用仍局限于宽度小于等于800mm、低表面质量要求的普碳钢中、窄板带材，对于在国内占据更大市场及技术附加值更高的高表面质量要求的宽厚规格的板带材，目前大部分仍旧利用化学、机械和抛丸等高污染的工艺或方法进行冷轧前的除鳞工作，对人和环境都危害极大。现有的高压水射流喷砂除鳞技术和设备采用开卷/收卷连续式输送，清理时，板带材一面受喷砂清理，另一面则由金属板支撑，以防板带材受高压水射流喷砂冲击产生的连续振动影响清理效果。该方式适用于清理薄板带材、窄板带材，对于高表面清理质量要求的中厚钢带(材)和宽钢带(材)，存在平稳输送困难、表面存在划伤、表面质量不均等问题，并且对整条生产线的设计和安装要求相当高，不利于工业应用和后期维护。
此外，现有板带材输送机构主要针对的是板带材热轧线和冷轧线设计，板带材的输送时主要是靠夹送辊的夹送和卷曲机的拉拽或输送辊轮的输送完成，始终只受到与板带材输送方向相同的拉力或推力。而利用高压水射流喷砂无酸清理板材金属表面时，为了防止除鳞喷头直接喷射到输送及侧边限位辊轮上，清理箱内除鳞喷头喷射方向与板带材输送方向垂直，板带材不仅始终受到与板带材输送方向相同的拉力或推力，而且当板带材输送到除鳞喷头喷射位置清理时，在对应的喷砂清理位置将受到来自除鳞喷头的沿板带材输送方向垂直的推力，使板带材偏离原有的输送方向，不利于高压水射流喷砂无酸清理工艺对板带材表面进行覆盖 式喷砂处理，因此，现有的板带材输送机构并不能用于高压水射流喷砂无酸清理的清理线上。

与现有技术相比，本发明的优点在于：
本发明的高压水射流喷砂清理装置，通过在板带材的上下侧对称设置喷砂的喷头，使板带材在清理的过程中上下方向的受力平衡，避免了单向喷砂冲击力造成板带材表面的下沉或上翘，而喷头沿输送方向梯度倾斜设置，前一喷头喷出的磨料不会遗留在后一喷头的喷射清理区域内，即相邻喷头的互不干扰，依次清理，从而使清理过程稳定可控。同时，通过清理箱内水平输送辊轮和夹送机构，从而使板带材的输送更加平稳简便，同时在输送过程保持与清理箱内水平输送辊轮滚动摩擦，避免了对板带材的表面的划伤破坏，通过水射流清理线实现了板带材的清理-冲洗-烘干-检测的流水化作业，提高了板带材的清理效率；通过正反方向的清理设置，提高了板带材的表面质量。
本发明根据所需清理的板带材的长度，在板带材输送方向的两侧合理设置上下料侧边限位辊轮、清理箱内固定侧导位辊轮位置和可调侧导位辊轮，使板带材在喷砂清理过程中即使受到由所述除鳞喷头产生的与其输送方向垂直的垂直力也不发生扭转，保持原有输送方向平稳输送。在上料输送辊道和下料输送辊道分别设置所述上料检测装置和所述下料检测装置，可对板带材快速定位，提高生产效率。在清理箱内水平输送辊轮或水平输送辊轮上部设置压力辊轮，增加了板带材的驱动摩擦力，保证了不同规格的板带材均能平稳进入并通过清理箱完成喷砂清理。
本发明将高压水射流喷砂清理工艺与板带材输送系统结合，实现了不同规格的板带材利用高压水射流喷砂无酸清理工艺对其表面清理时的连续平稳输送，并实现了自动化、高效清理。同时，本发明结构简单紧凑，成本低廉，输送方便，操作简单，生产效率高，表面清理效果好，清理后表面磨料易于冲洗收集，无污染。

具体实施方式
以下结合附图对本发明的实施例进行详细说明，但是本发明可以由权利要求限定和覆盖的多种不同方式实施。
如图1～图5所示，本发明首先公开了一种高压水射流板带材喷砂除鳞清理装置，包括清理箱7、冲洗箱18、磨料罐27、磨料收集箱24、除鳞喷头6和夹送机构51，冲洗箱18设置于清理箱7的输出端，清理箱7的输入端和冲洗箱18的输出端均设置有推拉板带材5的夹送机构51(在本实施例中，夹送机构51采用上下对称设置的滚动输送轮57压紧然后通过滚动推送来实现，该种滚动输送轮57的输送方式相对其他输送方式可以保证在高压水射流产生较大侧向推力和冲击力的情况下，上下设置的滚动输送轮57仍然能够保证在板带材5输送全过程中对其夹紧，进一步减少板带材5的横向侧移或者振动等影响板带材5表面清洗质量的因素或使用开卷卷取机构，推动板带材5移动)，同时实现对板带材5的先推后拉的过程，保证板带材5运动过程的连续性。除鳞喷头6与磨料罐27连接，而磨料罐27设置于清理箱7的上方，从而便于向除鳞喷头6输送高质量浓度的磨料流，且除鳞喷头6相对经过清理箱7的板带材5对称设置(也可以独立布置)，磨料收集箱24设置于清理箱7的底部。
在本实施例中，任一除鳞喷头6均安装在一可调节除鳞喷头6的安装高度和安装角度的喷头安装调节机构54上，喷头安装调节机构54安装在清理箱7内(其中喷头安装调节机构54为螺杆和螺母等简易的机械式调节，也可以为电机驱动的自动化调节升降或者偏摆的机构)，通过喷头安装调节机构54即可实现调节除鳞喷头6的倾斜角度α和靶距L 2，参见图3，相对经过清理箱7的板带材5对称设置的两个除鳞喷头6形成一喷头组53，喷头组53的除鳞喷头6朝向经过清理箱7的板带材5的宽度方向以相同的倾斜角度倾斜设置，即板带材5上、下的除鳞喷头6相对于板带材5上下表面的对称面呈对称分布，上方的除鳞喷头6与上表面形成倾斜角α、靶距L 2和下方的除鳞喷头6与下表面形成的倾斜角和靶距一致，上、下方的除鳞喷头6对板带材5形成的冲击合力平行于板带材5宽度方向，实现板带材5上、下表面的横向对冲喷砂清理(也可以与所述清理箱内板带材5的运动方向呈一定角度的斜向对冲喷砂清理)，从而喷头组53的冲击力对板带材5表面的下沉或上翘均不构成影响。
在本实施例中，还包括多组用于输送板带材5的清理箱内水平输送辊轮11，清理箱内水平输送辊轮11形成输送板带材5的输送线，输送线的两侧设置对有相对位置可调的侧向导辊60，清理箱内水平输送辊轮11和侧向导辊60的转动辊表面设置有橡胶层，用以防止传送过程中对板带材5的刮伤。通过相对位置可调的侧向导辊60，从而可以适应不同宽度的板带材5，夹送机构51布置在清理箱7前后给板带材5提供平稳连续的输送动力，清理箱内水平输送辊轮11支撑板带材5平稳输送。在高压水射流喷砂冲击力作用下板带材5会产生向一侧偏移趋势，设置侧向导辊60以防止这种偏移趋势的扩大。夹送机构51、侧向导辊60和清理箱内水平输送辊轮11共同配合，实现板带材5的平稳输送。
在本实施例中，喷头组53沿经过清理箱7的板带材5的长度方向均匀梯度设置，喷头组 53的除鳞喷头6均朝向板带材5的同一宽度方向，且除鳞喷头6在板带材5上喷射扩散形成一喷射影响区域59，喷射影响区域59内包括有对板带材5起直接喷射清理作用的喷射清理区域58，其中，喷射清理区域58为除鳞喷头6喷出的磨料直接作用、起清理作用的区域，与除鳞喷头6的喷射方向直接相对，而喷射影响区域59则为除鳞喷头6喷出的高压磨料射流与板带材5碰撞后向外扩散形成，在本实施例中，先进入板带材5上方的除鳞喷头6所形成的喷射影响区域59与后进入板带材5上方的除鳞喷头6所形成的喷射清理区域58相接或者部分重叠。如图5所示，这样可严格保证前一除鳞喷头6(即先进入板带材5上方的除鳞喷头6)喷出的磨料不会遗留在后一除鳞喷头6(即后进入板带材5上方的除鳞喷头6)的喷射区域内进而影响后一除鳞喷头6对板带材5的表面清理质量(当除鳞喷头6开始喷射时，该除鳞喷头6在板带材5的喷射清理区域58内存在的磨料越多，磨料射流会作用于遗留在该区域的磨料上，由于遗留在该区域的磨料的阻隔等影响，其喷射处理的效果越差)，即相邻除鳞喷头6的喷射互不干扰，顺次清理，从而使清理过程达到均匀稳定可控。在具体设置时，考虑到工艺和安装精度等因素，两个相邻的除鳞喷头6分别形成的喷射清理区域58与喷射影响区域59在板带材5的宽度方向上部分重叠，从而能够保证两个区域的相接处能够被清理，避免两相接处存在未被清理的盲区。同时，喷头组53的喷射宽度大于板带材5的宽度，即控制清理箱7内除鳞喷头6的喷砂清理区域略宽于板带材5的宽度B，且喷砂清理可覆盖板带材5的某个侧表面从而可以对板带材5的边缘同样完成清理作业，实现单一清理箱7就可完成宽度为B的板带材5的上、下、侧表面喷砂清理工作。
在本实施例中，多个相邻的喷头组53形成一除鳞单元52，其中，清理箱内水平输送辊轮11辊边间距设计依据是板带材5在喷砂清理时能从前一个清理箱内水平输送辊轮11顺利输送到后一个清理箱内水平输送辊轮11，且除鳞单元52喷砂不会直接冲击到清理箱内水平输送辊轮11和侧向导辊60，避免高压磨料射流对清理箱内水平输送辊轮11和侧向导辊60的冲刷破坏，清理箱内水平输送辊轮11和侧向导辊60沿输送线间隔设置，且清理箱内水平输送辊轮11和侧向导辊60靠近设置，除鳞单元52设置于清理箱内水平输送辊轮11和侧向导辊60之间。
在一个优选实施例中，侧向导辊60包括清理箱内固定侧导位辊轮13和可调侧导位辊轮14，如图6和8，该实施例在下面进行详述。
然后，本发明实施例公开了一种水射流清理线，包括一个或者两个以上(可以采取两个、三个、四个等多个数量、多种形式的排列组合方式)依次连接的高压水射流板带材喷砂除鳞清理装置，水射流清理线的输出端依次设置有板带材5可通过的干燥装置55和检测装置56。板带材5表面残余的磨料在清理箱7内的冲洗箱18中冲洗干净，每个清理箱7内的磨料独立 循环和供给。干燥装置55位于最后一个夹送机构51的后端，位于检测装置56之前。干燥装置55用于去除清理残余水渍，便于进行板带材5在线检测和板带材5下一步工序。检测装置56对清理干燥后的板带材5表面进行实时检测，并通过控制系统或操作人员及时调整压力、靶距、喷射角度α等参数，从而保证生产出高表面质量的宽厚规格板带材5。
在本实施例中，水射流清理线包括相互连接的正向喷射清理线和反向喷射清理线，正向喷射清理线和反向喷射清理线内均包括一个或者两个以上依次连接的高压水射流板带材喷砂除鳞清理装置(具体数量视板带材5的尺寸、板带材5表面清理难度、板带材5表面清理质量要求而定)，正向喷射清理线内的除鳞喷头6朝向板带材5的同一宽度方向，反向喷射清理线内的除鳞喷头6朝向板带材5的同一宽度方向，且正向喷射清理线和反向喷射清理线内的除鳞喷头6的喷头朝向相对垂直于板带材5宽度方向的竖直平面对称设置。即前后两个高压水射流板带材喷砂除鳞清理装置内除鳞喷头6数量相同，但是喷砂清理方向相反，从而使板带材5的上下表面经过两次喷砂清理方向相反的清理，使得清理后的板带材5表面质量更加均匀，满足板带材5对表面清理质量的高要求。并且，当板带材5厚度较大时，板带材5的两个侧面可在前后两个高压水射流板带材喷砂除鳞清理装置内依次被喷砂清理干净。
在本实施例中，可选的，本水射流清理线还可以这样设置：喷头组53沿水射流清理线的输送方向梯度均匀布置，当单一清理箱7完成宽度为B的板带材5喷砂清理工作时，通过串联布置N个高压水射流板带材喷砂除鳞清理装置，可清理宽度为N*B的板带材5，进而实现不同宽度规格的板带材5喷砂清理。
如图6～9，本发明还公开了一种高压水射流喷砂清理板带材的清理系统，包括板带材输送系统、高压水供给系统、高压水射流喷砂除鳞清理装置、冲洗箱、磨料供给回收分选系统、污水循环处理系统和智能电气控制系统。
如图6和图8所示，板带材输送系统包括上料输送辊道1、下料输送辊道2、侧边定位推钢机3、上下料侧边限位辊轮4、上料检测装置9、下料检测装置10、清理箱内水平输送辊轮11、清理箱内水平输送辊轮密封装置12、清理箱内固定侧导位辊轮13、可调侧导位辊轮14、侧导位调节机构15。
如图7和图9，高压水供给系统包括净水箱20、高压泵21、变频控制器22、压力输送管路23。
如图6，冲洗箱包括高压冲洗装置19。
如图7和图9，高压水射流喷砂除鳞清理装置包括清理箱7、磨料收集箱24、除鳞喷头6、除鳞喷头安装架25、冲丸装置26。
如图7和图9，磨料供给回收分选系统包括磨料罐27、供砂管28、供砂控制阀29、重量 传感器30、磨料筛分装置31、水力输送器32、水力旋流器33、溢流收集箱34、渣浆泵35、抽砂供水泵36。
如图7和图9，污水循环处理系统包括污水过滤器37、输水管道38、沉淀池39、污水泵40、反冲泵41。
智能电气控制系统通过PLC程序控制整个清理系统的水泵、阀、电机正常启停及检测装置，自动诊断和报警。
冲洗箱18安装在清理箱7的出口端，板带材输送系统安装在清理箱7进口和冲洗箱18的出口两端。
清理箱内固定侧导位辊轮13和可调侧导位辊轮14分别位于板带材5输送方向的两侧；清理箱内固定侧导位辊轮13固定布置在板带材5沿输送方向的同一侧且在除鳞喷头6喷射方向一侧，对板带材5实现宽度方向单边定位；可调侧导位辊轮14布置在板带材5的另一侧，且可通过侧导位调节机构15自动调节并平行移动位置，以适应不同规格宽度的板带材5，对板带材5实现宽度方向限位，实现清理过程平稳输送。可调侧导位辊轮14沿板带材5输送方向位于全部的清理箱内固定侧导位辊轮13的进出两侧。
除鳞喷头6朝着板带材5的宽度方向喷射(即沿着垂直于板带材5的输送方向喷射)，使得板带材5在除鳞喷头6的清理位置对应受到沿着板带材5的宽度方向的力F，如图6，而这个力F将使得板带材5偏离原有的输送方向。为了使得板带材5继续保持原有的输送方向，清理箱7内任意连续3个清理箱内固定侧导位辊轮轴线13之间的距离L1或L2和可调侧导位辊轮14与其最近的第2个清理箱内固定侧导位辊轮13的轴线之间的距离L3或L4均小于需要输送的板带材5的长度L。
板带材5进入除鳞喷头6和离开除鳞喷头6时由可调侧导位辊轮14和清理箱内固定侧导位辊轮13进行宽度限位，板带材5离开可调侧导位辊轮14后且在清理箱7内中途清理时，由清理箱内固定侧导位辊轮13进行宽度定位。
板带材5清理时和进出除鳞喷头6始终有至少两个清理箱内固定侧导位辊轮13或可调侧导位辊轮14和清理箱内固定侧导位辊轮13对其进行宽度限位。
清理箱内固定侧导位辊轮13布置在两个未安装除鳞喷头6的清理箱内水平输送辊轮11之间，以防止除鳞喷头6喷射打击到清理箱内固定侧导位辊轮13，同时可确保任意板带材5在清理箱内通过和被清理时宽度定位侧的边线位置不发生改变。
上料输送辊道1和下料输送辊道2均由两个及以上的水平输送辊轮16组成；清理箱内水平输送辊轮11与板带材5接触的位置均外包橡胶等塑料耐磨材料；水平输送辊轮16和清理箱内水平输送辊轮11均水平间隔布置在板带材5下侧，并变频驱动电机或独立电机通过链轮 和链条连接同步驱动，实现支撑并输送板带材5。
上下料侧边限位辊轮4位于板带材5输送方向的两侧，可一侧的侧边限位辊轮固定一边侧边限位辊轮可调或两侧的侧边限位辊轮可调，用于板带材5在上料输送辊道1和下料输送辊道2上的宽度限位。
侧边定位推钢机3布置于上料输送辊道1一侧，并与上料输送辊道1平行布置，用于将板带材5推送至上料输送辊道1上的指定位置。
上料检测装置9和下料检测装置10，分别布置于上料输送辊道1和下料输送辊道2处,通过检测板带材5的宽度和厚度确定上下料侧边限位辊轮4、可调侧导位辊轮14以及压力辊轮8的所需移动的距离或位置。
压力辊轮8设置于水平输送辊轮16或清理箱内水平输送辊轮11上方，增加板带材5在输送过程中的驱动摩擦力。
冲洗箱18内采用与上料输送辊道1或下料输送辊道2相同结构的辊道输送和上下料侧边限位辊轮4限位，或者采用清理箱内水平输送辊轮11、清理箱内水平输送辊轮密封装置12进行输送密封和清理箱内固定侧导位辊轮13、可调侧导位辊轮14以及侧导位调节机构15进行限位。
高压泵21由净水箱20供水，通过变频控制器22调节控制高压泵21输出压力水的压力，高压泵21通过压力输送管路23与除鳞喷头6连接。
高压冲洗装置19与高压泵21之间通过压力输送管路连接，利用高压水冲洗掉板带材5上的全部附着物。
清理箱7内安装除鳞喷头安装架25，除鳞喷头6安装在除鳞喷头安装架25上，清理箱7下方安装磨料收集箱24用来收集完成清理的磨料并通过水力输送器32将收集的磨料送回至磨料罐27。清理箱7内壁上除鳞喷头6可以喷射到的位置均安装耐磨板。冲丸装置26包括冲丸喷嘴42，并安装在清理箱7内尾部的板带材输送线上部2排冲丸喷嘴和下部1排冲丸喷嘴42，便于将板带材5表面清理后残留在其表面的磨料全部冲洗落入清理箱7下方的磨料收集箱24中。所述除鳞喷头6采用中国专利可拆换组合式高压水喷砂喷头(专利号：201320176948.3)中所述。
清理箱7内，除鳞喷头6朝向板带材5的同一宽度方向且沿板带材5的输送方向呈梯度设置，除鳞喷头6设置于板带材5上下两侧面且相对于板带材5对称布置，既能确保除鳞喷头6能够将板带材5的宽度方向依次覆盖清理(形成板带材被清理区域17)，又能使除鳞喷头6的清理效果不受到影响，还可以保证清理箱内水平输送辊轮11不被除鳞喷头6喷射破坏。除鳞喷头布置方式采用中国专利一种高压水射流板带材清理装置及水射流清理线(专利号： 201820842714.0)中所述。
磨料罐27安装在清理箱7的上方且中部位置，其输出端与除鳞喷头6之间通过供砂管28连接为清理箱7内的除鳞喷头6供砂。重量传感器30安装在磨料罐27下方，磨料筛分装置31安装在磨料罐27上方，供砂控制阀29安装在磨料罐27的下砂口下方，磨料罐27与除鳞喷头6之间通过供砂管28连接；水力输送器32安装在磨料收集箱24的下方并通过管路与磨料罐27连接，抽砂供水泵36通过管路连接水力输送器32。水力旋流器33安装在清理箱7的上方且前部位置，其进水口通过渣浆泵35与设置在清理箱7侧方溢流口位置的溢流收集箱34相连，其下方出口与清理箱7连接以便磨料收集箱24收集分选回收的磨料，其上方出口与沉淀池39连接用于排出含废弃的氧化皮及细碎磨料的污水。溢流收集箱34位于清理箱7的侧方且前部位置，收集从清理箱7的溢流口溢流出的含磨料和氧化皮的污水。渣浆泵35进水口与溢流收集箱34连接。所述磨料罐结构采用中国专利高压水射流喷砂磨料供砂罐(专利号：201320177049.5)。
污水过滤器37进水口通过输水管道38与污水泵40连接，其出水口与净水箱20连接。反冲泵41的进水口通过管道与净水箱20连接，其出水口与污水过滤器37连接。
清理箱包括第一清理箱49和第二清理箱50，第一清理箱49位于第二清理箱50前端，第一清理箱49和第二清理箱50结构相同，即第一清理箱49和第二清理箱50串联将板带材5上下两面覆盖式全部清理两遍，或者第一清理箱49和第二清理箱50结构的区别只是除鳞喷头6在板带材5宽度方向上布置位置依次错开，即第一清理箱49和第二清理箱50能依次在宽度方向分别单独清理一定宽度以将板带材5上下两面覆盖式全部清理。
根据板带材5的宽度规格不同，可自动调节上下料侧边限位辊轮4和侧导位调节机构15上的可调侧导位辊轮14限位时，可同步启停相应的宽度区域的除鳞喷头6，方便快捷、节能，同时清理箱7、清理箱内水平输送辊轮11、清理箱内固定侧导位辊轮13和可调侧导位辊轮14受到最大保护，适应性强。
高压水射流板带材喷砂除鳞清理的清理系统的增加部件包括：磨料罐27与除鳞喷头6连接的供砂管28上安装有定型硬管44，防止供砂管28变形破坏后影响供砂效果。磨料罐27内冲砂嘴45的输水管路上可增加一个带有阀门47(设置于冲砂泵46的一旁)的防堵管路，防止输水管路发生虹吸现象导致冲砂嘴45进砂堵塞。在板带材5下方安装的除鳞喷头6上可增加一块挡板48，以便在垂直方向可盖住除鳞喷头6出口，防止从板带材5或清理箱7内顶部的磨料垂直掉落进入喷嘴内堵塞除鳞喷头6。在高压泵21和除鳞喷头6之间增加高压过滤装置43，以提高进入除鳞喷头6的水质，减少除鳞喷头6堵塞。
板带材5在高压水射流板带材喷砂除鳞清理的清理系统中的清理过程为：板带材5首先 被吊放在上料输送辊道1上，由侧边定位推钢机3推送，同时上料检测装置9检测其宽度或厚度，经检测反馈信号后将板带材5推送至指定位置，接着上下料侧边限位辊轮4对板带材5完成侧边限位，然后启动上料输送辊道1和清理箱内水平输送辊轮11对板带材5输送；当板带材5到达第一清理箱49入口位置时，通过侧导位调节机构15自动调节位于第一清理箱49入口处可调侧导位辊轮14，对即将进入的板带材5进行宽度方向限位，然后板带材5进入第一清理箱49内同时进行上下两侧面喷砂清理；当板带材5到达第一清理箱49出口位置时，通过侧导位调节机构15自动调节位于第一清理箱49出口的可调侧导位辊轮14，对即将离开的板带材5进行宽度方向限位；板带材5在第二清理箱50内的输送、限位和清理过程类似，当板带材5在第一清理箱49和第二清理箱50清理后即完成板带材表面的喷砂清理。之后，板带材进入冲洗箱18利用高压水冲洗掉其表面的全部附着物。最后经下料检测装置10检测，启动下料输送辊道2送出清理后的板带材5，至此，板带材5完成了在高压水射流板带材喷砂除鳞清理的清理系统中的全部清理过程，板带材5被清理完毕。
为了延长部分板带材5的仓储时间，也可在冲洗箱18之后增加吹扫装置和烘干装置，对板带材表面进行干燥处理。
在本实施例中，可选的，本高压水射流板带材喷砂除鳞清理的清理系统还可以这样设置，每个清理箱7清理宽度为B，则通过除鳞喷头梯度错开布置可串联N个清理箱7，则可以清理宽度规格为B*N的板带材5。
如图10～12，在一个优选实施例中，清理箱内水平输送辊轮密封装置12采用密封盘和弯折通道的密封结构。清理箱内水平输送辊轮11包括辊轮129。
支撑轴121的两端通过螺母122螺纹连接固定于支撑部件123上，支撑轴121上从左到右依次安装有轴环124、密封盘125、第一密封件126、密封环127、轴承128、辊轮129、轴承128、密封环127、第二密封件1210、定位轴套1211、密封盘125、轴环124。辊轮129通过安装在其两端的轴承128径向定位在支撑轴121上，辊轮129通过轴承128实现滚动。密封盘125通过轴环124和支撑轴121的轴肩或定位轴套1211进行轴向定位。轴承128的内圈通过支撑轴121的轴肩或定位轴套1211进行轴向定位，轴承128的外圈通过辊轮129进行轴向定位，且轴承128与辊轮129相互轴向定位。
为防止轴承128因磨料射流打击磨损而毁坏，设置了密封盘125以防止钢丸/砂的对轴承128和密封件的直接打击。密封盘125安装在支撑轴121上并紧邻辊轮129的两个端面。在密封盘125上沿周向设有第一凹槽，在辊轮129的两个端面上沿周向设有第二凹槽，第一凹槽与第二凹槽交错相扣形成弯折通道。该弯折通道大致呈S形，其边界包括密封盘125上的密封盘斜面与辊轮129上的辊轮斜面。密封盘斜面包括构成第一凹槽侧壁的第二斜面1213和 第四斜面1215。辊轮斜面包括构成第二凹槽侧壁的第一斜面1212和第三斜面1214，以及靠近辊轮中心孔的第五斜面1216。第三斜面1214和第五斜面1216在径向上位于第二斜面1213和第四斜面1215之间，第二斜面1213在径向上位于第一斜面1212和第三斜面1214之间。此外，密封盘125周向外壁构成的斜面在径向上位于第一斜面1212和第三斜面1214之间。
当高压水射流板带材喷砂除鳞清理设备进行正常运行作业时，安装在主清理单元中的水平限位托辊会受到来自各个方向的反弹的磨料的打击。密封盘125和辊轮129之间设置的第一斜面、第二斜面、第三斜面、第四斜面和第五斜面共5个斜面，在密封盘125和辊轮129之间构成了多个反弹减速面。当部分磨料进入密封盘125和辊轮129之间缝隙时，由于多个反弹面的存在，磨料经过各个斜面多次反弹变向速度减小，减小了打击力，增长了运行路径，从而减小了磨料进入密封盘125和辊轮129之间的缝隙的量，减轻了磨料对密封件或轴承的直接损坏。
密封盘125的斜面与轴线I 1I 2在OI 2方向的夹角为α，辊轮129的斜面与轴线I 3I 4在O 1I 3之间的夹角为β，α和β两个角度均为锐角。密封盘125周向外壁构成的斜面与OI 2夹角为锐角。当辊轮129旋转时，由于离心力的存在已进入密封盘125与辊轮129之间缝隙的磨料，容易被甩出，也减少了对密封件或轴承有损坏的磨料的量，有效防止了水平限位辊轮被卡死现象的发生。
如图13，在一个优选实施例中，清理箱内固定侧导位辊轮13和可调侧导位辊轮14采用具有弯折通道的密封结构的限位辊轮。限位辊轮包括第二辊轮606。
第二支撑轴603通过下端的第1螺母601螺纹连接固定于支撑件602上，第二支撑轴603上从下到上依次安装有第二密封环604、第二轴承605、第二辊轮606、第二轴承605、第2螺母608。第二辊轮606通过安装在其两端的第二轴承605径向定位于第二支撑轴603上。辊轮盖607紧密盖在第二辊轮606的上端面上，对第二辊轮606上端完全密封，保护辊轮上端的第二轴承605不受到磨料打击磨损。第二支撑轴603上的两个第二轴承605和第二辊轮606通过支撑轴的轴肩和第2螺母608互相定位，且第二辊轮606通过两个第二轴承605轴向定位并实现滚动。
为防止下端的第二轴承605因磨料的打击磨损而毁坏，第二支撑轴603沿周向设置有第一凸棱和其上方的第二凸棱，第一凸棱和第二凸棱之间形成第一凹槽，在第二辊轮606下端靠近中心孔的内侧设有第二凹槽，第一凹槽与第二凹槽交错相扣形成弯折通道。弯折通道大致呈S形，该弯折通道的边界包括第二支撑轴603上的支撑轴斜面与第二辊轮606上的辊轮斜面，支撑轴斜面与OI 1夹角为锐角，辊轮斜面与OI 2夹角为锐角。支撑轴斜面包括构成第一凹槽侧壁的第1斜面6012和第3斜面6013，以及构成第二凸棱上侧面的第5斜面609。辊轮 斜面包括构成第二凹槽侧壁的第2斜面6011和第4斜面6010，以及第二辊轮606最下端外侧的第6斜面6017。第2斜面6011在轴向上位于第1斜面6012和第3斜面6013之间，第5斜面609和第3斜面6013在轴向上位于第2斜面6011和第4斜面6010之间。第二辊轮606下端面构成的第6斜面6017与OI 2夹角为锐角，第6斜面6017在轴向上位于第1斜面6012和第3斜面6013之间。
在第二辊轮606和第二支撑轴603之间设置了第1斜面6012、第2斜面6011、第3斜面6013、第4斜面6010、第5斜面609和第6斜面6017共6个斜面，构成了多个反弹面。当高压水射流板带材喷砂除鳞清理设备进行正常运行作业时，安装在主清理单元中的斜向限位辊轮会受到来自各个方向的反弹的磨料的打击。当部分磨料进入第二辊轮606和第二支撑轴603之间缝隙时，由于多个反弹面的存在，钢丸经过多次反弹变向减速，减小了其打击力，增长了其运行路径，从而减小了磨料残留在第二辊轮606和第二支撑轴603之间的缝隙中的量，减轻了磨料对第二密封环604或第二轴承605的损坏。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
