Description

一种高效稳固电解槽 技术领域
本发明属于冶金板带表面处理技术领域，具体涉及一种高效稳固电解槽。
背景技术
冷轧不锈钢退火时，由于退火炉燃烧烟气中含有一定量的氧化性气体，比如O 2和H 2O，会使带钢表面生成含有铁、铬、镍、锰、硅等元素的数层薄而致密的氧化皮，在带钢接近基体侧还会有一层贫铬层，这些因素均会导致带钢耐腐蚀性能下降，表面粗糙度变大。为满足带钢的表面质量要求，有必要经过物理及化学表面处理工艺将氧化皮和贫铬层去除。对于铬、铁氧化物利用电化学作用，使氧化皮溶解是常用的方式。因电解系统中常用介质会含有Cr6+、硝酸、硫酸等强氧化、腐蚀性介质，所以电解槽一般选用低碳钢衬胶衬砖槽体、纯金属槽体、塑料槽体等型式，但从投资及操作维护方面分析，现有电解槽会有如下缺点：
(1)低碳钢衬胶衬砖槽体，为避免电解液穿过胶层和砖层腐蚀钢槽基体，对衬胶衬砖质量要求高。但由于生产过程中电解参数变化或停机维护时都会造成电解槽温度变化较大，而胶泥层、砖层、胶层与钢基体之间因膨胀系数不一致，不可避免会发生各层热胀冷缩位移不同，随着时间推移，容易造成槽体泄漏。钢衬胶衬砖槽体因为很难确定漏点位置而不好维护。
(2)纯金属槽体为耐电解液的强氧化性和腐蚀性，需要用到高硅铸铁等材质。高硅铸铁虽然具有卓越的耐腐蚀性，但由于硬度高，力学性能差，不但会造成投资费用高而且制造加工及后期维护困难。
(3)塑料槽体，常用PPH槽体，具有耐腐蚀性好、性价比高、制造及维护等优点，但是电解液中的Cr 6+，NO 3 -等强氧化性离子会对槽体的焊缝造 成氧化性腐蚀，造成槽体寿命缩短。
发明内容
本发明的目的是针对现有塑料槽体存在的上述缺陷，提供一种高效稳固电解槽，实现了避免槽体主焊缝被氧化的目的。
为此，本发明提供了一种高效稳固电解槽，包括主槽体，以及设置在主槽体两端的回流槽体；所述主槽体包括槽底板、槽侧板和槽盖，所述槽底板与槽侧板之间焊接有用于保护槽底板与槽侧板间主焊缝的斜板，所述主槽体内部沿其长度方向间隔设置有多组电极板组，所述电极板组包括上下相对布置的两个电极板，所述主槽体内设有用于对电极板组进行定位固定的电极定位架，所述回流槽体内设置有使带钢沉浸于主槽体内电解液中的沉浸辊。
进一步的，各所述电极板组的头部和尾部均设置有阻挡带钢与电极板接触的电极保护板。
进一步的，所述电极保护板为锯齿形结构，包括顶板、底板、前侧板和后侧板，所述顶板和底板为整块锯齿板材，所述顶板和底板的锯齿端通过后侧板焊接，所述顶板和底板上与锯齿端相对的一侧通过前侧板焊接，所述底板比顶板向外延伸3～10mm，且所述电极保护板的底板一侧靠近带钢布置。
进一步的，所述顶板、底板、前侧板和后侧板均采用耐电解液腐蚀的塑料材质。
进一步的，所述电极定位架包括定位框架、定位销和支撑块，所述定位框架置于所述主槽体侧壁外沿上方，所述支撑块分上下两层叠加置于定位框架和主槽体侧壁外沿之间，上、下电极板的边沿分别固定于上、下层支撑块中，所述定位框架、支撑块和主槽体侧壁外沿通过定位销固定，且相邻的电极定位架之间通过塑料板材隔开。
进一步的，所述定位框架和定位销为金属材质，所述支撑块为塑料材 质。
进一步的，所述槽侧板上均布有U型钢结构。
进一步的，相邻两个所述电极板组之间设置有用于支撑带钢的支撑辊。
进一步的，所述主槽体上还设置有用于揭开和封闭槽盖的揭盖机。
进一步的，所述回流槽体的带钢进出侧设有挤干辊。
与现有技术相比，本发明的有益效果：
(1)本发明提供的这种高效稳固电解槽通过设置斜板对主焊缝进行保护，使主焊缝与电解液不用直接接触，有效解决了现有塑料材质槽体的主焊缝易被氧化腐蚀的问题，提高了电解槽的使用寿命。
(2)本发明提供的这种高效稳固电解槽在电极板组的头部和尾部设置电极保护板，而在电极板中部不设置保护板，相对于传统的网格保护板型式，不但大幅度提高了电极板有效面积，缩短了电解槽长度，减少了电极板数量和能源介质耗量，而且在带钢板形缺陷通过电极板时，不会直接对保护板焊缝进行磨损导致保护板脱落，损伤电极和带钢，甚至造成电解液外溢事故。
(3)本发明提供的这种高效稳固电解槽采用了外壁U型钢结构保护，在减少主槽体板材用量的同时，加强了主槽体的强度，同时通过电极定位架对电极板组进行定位固定，在减少电极板热胀冷缩对槽体受力，造成损害的同时，也使上下电极板形成一体，整体电极板组变形小，提高了电解槽的稳固性。
以下将结合附图对本发明做进一步详细说明。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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它实施例，都属于本发明保护的范围。
在本发明的描述中，需要理解的是，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征；在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
如图1和图2所示，本实施例提供了一种高效稳固电解槽，包括主槽体3，以及设置在主槽体3两端的回流槽体1；所述主槽体3包括槽底板14、槽侧板4和槽盖6，槽底板14和槽侧板4焊接形成主焊缝，而为了避免电解液对此主焊缝造成氧化性腐蚀，影响槽体寿命，在所述槽底板14与槽侧板4之间连续焊接有用于保护此主焊缝的斜板13，具体的，斜板13可以为一道或多道，通过斜板13的设置可以使主焊缝与电解液不用直接接触，避 免了主焊缝被氧化、裂纹后发生电解液泄漏事故，同时斜板13与槽底板14和槽侧板4之间焊缝若被腐蚀，可比较方便的进行区段更换或整体更换，不影响主槽体3强度，大幅度提高了槽体的寿命；所述槽盖6对主槽体3进行密封，避免主槽体3中腐蚀性及强氧化性酸雾外溢，而为了方便槽盖6的开关，优化的，所述主槽体3上还设置有用于揭开和封闭槽盖6的揭盖机7。所述主槽体3内部沿其长度方向间隔设置有多组电极板组，所述电极板组包括上下相对布置的两个电极板9，所述主槽体3内设有用于对电极板组进行定位固定的电极定位架8，通过电极定位架8使得电极板组的位置相对固定，减少电极板9热胀冷缩对槽体受力造成损害；所述回流槽体1内设置有使带钢沉浸于主槽体3内电解液中的沉浸辊2，通过沉浸辊2作用使得带钢在张力作用下能从上、下两个电极板9中间穿过。优化的，相邻两个所述电极板组之间设置有用于支撑带钢的支撑辊11，避免带钢在重力作用下下沉而与电极板9接触，划伤带钢表面；所述回流槽体1内远离主槽体3一侧设有挤干辊12。本实施例中主槽体3和回流槽体1均为耐电解液腐蚀的塑料槽体，可采用PPH、PVDF、HDPE等材质，这样本实施例的这种高效稳固电解槽在基于塑料材质槽体优点的同时，采取措施避免了槽体主焊缝被氧化，提高槽体使用寿命。
带钢通过电极板组时，由于带钢本身边浪、镰刀弯或带钢失张，容易与上、下电极板9接触，划伤带钢表面，所以电极板9一般都设置网格型塑料保护板，但常规的网格型塑料保护板一方面挡住了电极板9的有效区间，另外随着带钢的剐蹭，焊缝位置很容易脱落，从而堵住槽体的回流口导致槽体液体溢出事故。基于此，本实施例中只在各所述电极板9的头部和尾部均设置有阻挡带钢与电极板9接触的电极保护板10，电极板9中部不设置电极保护板10，利用带钢本身的刚性，当带钢出现失张或镰刀弯等缺陷时，在电极板9长度及宽度方向上，带钢首先接触的是电极保护板10，同时本实施例中的这种电极保护板10安装形式大幅度提高了电极板9有效 面积，减少电极板9数量和能源介质耗量的同时，对带钢和电极板9进行了有效保护。具体的，如图3所示，所述电极保护板10为锯齿形结构，包括顶板15、底板16、前侧板17和后侧板18，所述顶板15和底板16为整块锯齿板材，无拼焊结构，所述顶板15和底板16的锯齿端通过后侧板18焊接，所述顶板15和底板16上与锯齿端相对的一侧通过前侧板17焊接，所述底板比顶板向外延伸3～10mm，而在电极板上安装此电极保护板时，使该电极保护板的底板一侧靠近带钢布置，这样在带钢运行方向上，不会直接造成焊缝被带钢划伤，塑料板脱落现象。所述顶板15、底板16、前侧板17和后侧板18均采用耐电解液腐蚀的塑料材质，如PPH、PVDF、HDPE、UHMWPE等材质。
细化电极定位架8的结构，如图4所示，所述电极定位架8包括定位框架19、定位销21和支撑块20，所述定位框架19置于所述主槽体3侧壁外沿上方，所述支撑块20分上下两层叠加置于定位框架19和主槽体3侧壁外沿之间，上下对称布置的电极板9的边沿分别固定于上、下层支撑块20中，所述定位框架19、支撑块20和主槽体3侧壁外沿通过定位销21固定，这样上、下电极板9通过电极定位架8使之形成一体，避免了因支撑块移动导致电极板9错位现象，保证了电极板9安装的稳固性；进一步的，相邻的电极定位架8之间通过塑料板材隔开。具体的，所述定位框架19和定位销21为金属材质，所述支撑块20为塑料材质。
另外，所述槽侧板4上均布有U型钢结构5，该U型钢结构5在对槽侧板4进行结构加强的同时，能随主槽体3一起伸缩，能有效支撑电极板9的荷载同时，还可避免槽体变形与主焊缝撕裂，进一步保证了电解槽的稳固性。
综上所述，本发明提供的这种高效稳固电解槽采用多项保护稳固措施，利用斜板对槽体主焊缝与电解液进行了隔离，避免了电解液对主焊缝侵蚀、氧化而造成泄漏；采用了实用、稳固、占地面积小的电极保护板形式，不 但相对于传统的网格保护板型式大幅度提高了电极板有效面积，缩短了电解槽长度，减小了能源介质耗量，而且在带钢板形缺陷通过电极板时不会直接对保护板焊缝进行磨损导致保护板脱落，损伤电极和带钢，甚至造成电解液外溢事故；槽侧板采用外壁U型钢结构保护，在减少主槽体板材用量的同时，加强了主槽体的强度；对电极板组也设置了电极定位架，在减少电极板热胀冷缩对槽体受力，造成损害的同时，也使上下电极板及支撑板形成一体，整体电极板组变形小。
以上例举仅仅是对本发明的举例说明，并不构成对本发明的保护范围的限制，凡是与本发明相同或相似的设计均属于本发明的保护范围之内。
