Description
技术领域
本发明涉及分离陶瓷过滤板技术领域，尤其涉及一种陶瓷过滤机用陶瓷过滤板及其成型制作工艺。
背景技术
陶瓷真空过滤机是用于对矿浆中的固体和液体进行分离的设备，现有陶瓷真空过滤机的过滤部件一般是由12块扇形陶瓷板构成。其关键点利用过滤介质的内外压差，通过过滤介质间的微孔对矿浆中的水进行收集，微细颗粒则吸附在过滤介质的外表面形成滤饼而实现固液分离。陶瓷真空过滤机所具有的高效节能优势主要依赖于陶瓷过滤板的“透水不透气”特性，因此陶瓷过滤板是陶瓷过滤设备的核心。
陶瓷过滤板经过多年的发展，作为陶瓷真空过滤机核心组件的陶瓷过滤板生产制作也出现了两种分水量的制作方式。按照目前成型的方式可以分为粘结式陶瓷过滤板和机压一体成型陶瓷过滤板。这两种成型方式的陶瓷过滤板各自有着各自的优点，但是存在各自的缺点。
1、首先为粘结式陶瓷过滤板，这种成型方式的滤板一般采用的使用机压成型工艺。即通过干压拌料的方式，采用压机进行单片板的压制成型，再使用结合剂将两片对合粘结获得过滤板。这样就形成内部水路，外部骨架的成型工艺。再进行后期的加工制作。在实际的生产工艺流程为：配料-膜压单片-粘结-烧成-平面加工-装配附件。
采用粘接式陶瓷过滤板成型方式，在实际的使用环节中会存在如下缺点：
1-1、表层孔径不均匀：因为采用的压制工艺制作，存在压力的原因，制品表层会存在压力梯度关系，出现局部密度过实，因为采用的干压拌料工艺，会存在混料不均匀的原因。因此在实际产品制作环节制品表层的孔径就存在不均匀的现象。表层孔径不均匀，就不利于产品的过滤脱水作业。以150目刚玉砂制备的陶板为例，滤板表层的孔径分布一般在40～60um。
1-2、显气孔率偏低：因为采用的压制成型方式，一般需要使用300～600吨的压力压制成型，因此为了保证生坯的结构强度，坯体的显气孔率一般只能做到30%。
1-3、工序繁琐：采用这种成型工艺的陶板，需要大型成型设备，如拌料机、烘干机、大型压机，单种型号的边框模具。并且烧制完成后还需要对产品进行粘接作业。
1-4、结构强度差：因为采用的单片成型工艺。因此在后期的加工制作环节中，需要使用环氧树脂胶进行粘接作业。在粘接环节中，对胶体的使用量会存在诸多的不确定因素。对胶体的粘结剂用量和粘结压紧力不均匀，会造成基体开裂，内部多余粘结剂会在凸起支撑肋侧面产生毛糙凸出，占据水路增加排水阻力；其次，膜压单片为一面包有凸起支撑肋的不对称薄片结构，在干燥和烧成过程中极易引起变形，成品率不高，一般只有85％左右；另外，在粘结产品使用过程中，还容易发生粘结不强而开裂，抗抽吸应变力疲劳强度低，从而造成使用寿命变短。而且在实际的使用环节中还因为胶体的耐酸性问题，出现结构性的质量隐患，继而使用的后期出现爆板的风险。在实际的生产环节中设备的反清洗压力一般控制在0.1MPa以内。
针对于上述粘接式陶瓷过滤板存在的质量问题，后续进行了工艺的改善，推出了机压一体成型陶瓷过滤板。
2、机压一体成型陶瓷过滤板成型方式为采用预埋水道杆进行整体压制成型。虽然该成型方式获得了一体成型方式，提高了坯板的整体耐压强度（耐压强度在1.5～2.0MPa），但是在实际使用环节仍旧存在诸多的不足之处。
采用机压一体成型陶瓷过滤板成型方式，在实际的使用环节中会存在如下缺点：
2-1、板面孔径均匀差：因为采用的预埋不锈钢钢棍，所说义在压制环节造成有钢棍的位置压制密实度高，没有水道的位置密实度低，造成上述两个区域的通量不一，继而在后期的使用环节出现挂浆不一的现象。在实际的核查环节中板面孔径分布为35～55um。
2-2、陶板安装底座位置结构强度差：该工艺的制备环节，因为需要水嘴的汇集，水嘴的不锈钢钢棍直径偏粗，造成在压制环节中水嘴杆两侧的坯体强度最差，而该处是陶板安装底座的区域，该区域的结构强度下降，极易造成在实际使用环节中出现底座断裂的质量隐患。经核查底座附件陶板的抗折强度约为0.25MPa左右，低于板面的结构的强度（0.3MPa以上）。
2-3、上下层结构差异：因为采用的整体成型工艺，坯体的厚度是原先粘接板单片厚度的2倍。从而造成该工艺制备的陶瓷板胚体厚度将达到35～38mm。过厚的坯体势必在压制成型环节形成压力梯度，会造成底部的结构比较疏松，而顶部的结构又比较致密。因此两者的显气孔率差值在4～8%，顶层的显气孔率约在28～30%%左右，而底部的显气孔率约在33%～36%。两者的显气孔率差值势必造成在实际使用环节中两侧的挂料厚度也会出现差异。两侧挂料厚度的差值在2～5mm。
综上所述，目前现有技术存在的这两种生产工艺在实际使用环节中仍然存在诸多的不足之处。

所述4）中使用生产用料浆时，对所述生产用料浆进行搅拌，搅拌时间12min,使生产用料浆符合流动性标准，生产用料浆的流动性标准为每100ml的生产用料浆通过直径10mm的漏斗的时间在10～11s。
实施例3：
1、脱模版工装辅助准备
选好脱模版工装、边框、压框以及相匹配的泡沫内膜。
2、料浆的制备工作
白刚玉砂120目实现料浆的制备工作；对黏土进行改性，获得改性黏土实现料浆的准备工作。其中将黏土进行机械球磨，将球磨后的混合粉末样品放入马弗炉高温煅烧，煅烧温度615℃，煅烧3h，煅烧后的粉末在水中分散，制备成固含量为14%浆液；然后加入添加剂，所述添加剂为氟化锂与氟化钠的混合物，所述氟化锂与氟化钠的之间的质量比为2:1，所述添加剂用量为所述粉末质量的2%；搅拌1h，搅拌混合后，浆液经离心提纯，使用氧化铝进行胶凝性激活后，氧化铝用量为所述粉末质量的1%,激活30min，陈化4d，后经喷雾干燥，得到改性黏土。
料浆的配比工作如下表1：
按水与所述骨料的质量比0.25：0.74，将水称好，放入搅拌桶中。进行水温的测量工作，水温控制在20℃。如果水温达不到，低于上述数值可以进行加热操作，高于上述数值需要进行加冰块进行降温。启动搅拌的设备，将称好重量的纤维素干粉加入搅拌桶中，进行充分的搅拌处理，搅拌的时间控制在15分钟，确保上述的添加物能够充分的溶解。
上述搅拌结束后，将称好重量的其他原材料，改性黏土、钾长石、白云石、烧滑石、硼玻璃粉依次按照上述的顺序依次倒入搅拌桶中，进行充分的搅拌作业。搅拌时间控制在35分钟。然后通过pH调节剂进行调节，通过pH调节剂可以保证料浆的稳定流动性，保证料浆的悬浮稳定性，又保证料浆不会过早的固化。料浆的pH值控制在6。然后在进行陈腐作业，时间控制在12h以上，在进行生产使用作业。
3、陶板成型
3-1、将之前准备好脱模版工装准备好，并将所需要型号的边框模具放置脱模工装上面。并在相应的边框内侧打上脱模剂。便于制品的脱模工作。
3-2、上述工作准备完成后，可以将料浆进行初步的搅拌工作，时间控制在10分钟。料浆的流动性可以保证在100ml的料浆通过直径10mm的漏斗的时间控制在10～11秒。此时的料浆符合生产使用。
3-3、使用水舀将符合要求的料浆倒入已经安置好的边框模具内。每一种型号的边框模具均可以按照水舀的数量来进行定量管理。便于标准化的推广，需要边框模具内用到料浆的用量严格按照已经定好的重量进行添加。
3-4、放上相应型号已经制备好的泡沫内膜，并使用相应的型号的压框进行泡沫内膜固定。当边框模具内的料浆上表层的水分消失后，将压框取下。然后继续使用水舀将搅拌好的料浆注入上表层空缺的边框模具中去。在使用刮板将上表层的料浆刮平即可，完成上述的操作步骤。
3-5、此时启动模板工装底部脱水板的真空装置，此时边框模具内料浆内部的水分会快速向下运动，坯体内部的水分减少后，坯体进行了相应收缩。坯体和四周的边框模具开始发生分离。此时就可以将边框模具进行分离作业。
3-6、完成脱膜制备的坯体可以转运到烘房进行烘干作业，烘干条件80℃条件下烘干5天，即可以完成坯体的烘干作业。
3-7、数据核查
将烘干结束后的坯体送入到梭式窑内进行烧制作业。将烧制结束后的试块送检，进行数据检测，通过检测的结果与现有技术制备的陶瓷板检测结果对比，发现采用本发明工艺制备的陶瓷板的各项数据均达到显著效果，而且存在部分性能数据远超现有技术制备的陶板性能数据。
本发明陶瓷板检测结果如下表2：
通过表2可知，本发明制备的陶瓷板表层孔径均匀度得到了明显提升，底座强度进一步的加强，与现有技术对比，本发明制备出的陶瓷板性能得到了显著的提升，制作工艺得到了进一步的简化，明显提升了工作效率，有利于陶瓷板制备规模化的推广。
以上显示和描述了本发明的基本原理、主要特征及本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
