Description

瓷化骨料素坯防掉粉覆膜剂、覆膜系统及覆膜方法 技术领域
本发明属于瓷化骨料制备技术领域，具体涉及一种瓷化骨料素坯防掉粉覆膜剂、覆膜系统及覆膜方法，尤其适用于对各类危废协同制备的瓷化骨料进行覆膜保护。
背景技术
这里的陈述仅提供与本发明相关的背景技术，而不必然地构成现有技术。
瓷化骨料素坯成型完成后，需要将其置于回转窑中干燥、烧结，制备瓷化骨料。素坯在回转窑滚动干燥过程中，在素坯高温烧结出现部分液相(800℃左右)前，随着水份的流失，瓷化骨料素坯会和回转窑内壁相互摩擦而引起磨削掉粉。由于瓷化骨料的原料细度都在100目以下，骨料素坯摩擦掉粉容易引起窑内粉尘浓度过高，其中大部分粉尘随烧结烟气一起进入烟气处理工序，给后续的烟气处置带来一定困难；剩余少量粉尘会从窑头、窑尾及窑体连接部位外溢到环境中，导致环境粉尘超标。尤其对于各类危废协同制备的瓷化骨料，其磨削粉尘会导致车间环境不达标，无法通过环保验收。
发明内容
针对现有技术存在的不足，本发明的目的是提供一种瓷化骨料素坯防掉粉覆膜剂、覆膜系统及覆膜方法。通过在瓷化骨料素坯表面裹 覆一层高强度耐磨膜层，在素坯烧结前为素坯提供足够的耐磨度，大幅降低掉粉，并在骨料烧成中通过与骨料基体反应，有效提高骨料产品的强度等参数，以解决瓷化骨料生产过程中，素坯成型后干燥过程中，因瓷化颗粒素坯强度不足，容易导致磨削掉粉的问题。
为了实现上述目的，本发明是通过如下的技术方案来实现：
第一方面，本发明提供了一种瓷化骨料素坯防掉粉覆膜剂，其组分包括水玻璃、高粘剂凹土、高液限黏土和水。
第二方面，本发明提供一种瓷化骨料素坯防掉粉覆膜系统，包括：骨料整形机、浆料池和喷雾装置，其中，
所述喷雾装置包括输浆装置和至少一个喷头，喷头安装于输浆装置的输出端，输浆装置的输入端通过浆料泵与浆料池连通；
所述喷头设置于骨料整形机的整形腔的尾部。
第三方面，本发明提供一种瓷化骨料素坯防掉粉覆膜方法，包括如下步骤：
将水玻璃、高粘剂凹土、高液限黏土和水按设定比例混合后，高速离散搅拌，制成稳定浆液；
将制备得到的稳定的浆液均匀附着于瓷化骨料素坯的表面，形成覆膜。
第四方面，本发明提供一种附着有保护膜的瓷化骨料素坯，由所述覆膜方法制备而成。
第五方面，本发明提供一种瓷化骨料的制备方法，将覆膜后的瓷化骨料素坯置于回转窑中烧结，制备得到瓷化骨料。
第六方面，本发明提供一种瓷化骨料，由所述瓷化骨料制备方法制备而成。
上述本发明的一种或多种实施方式取得的有益效果如下：
1)通过在瓷化骨料素坯表面裹覆一层较高强度的保护膜，可以较好地提高骨料素坯在干燥过程中的表面耐磨度，从而最大限度地降低骨料生产中的粉尘产生量。
2)本发明的覆膜剂的组分是易于与骨料素坯材料形成结合体的无机非金属材料，其中硅铝含量较高，可有效提高骨料烧成过程中表面的耐温性，避免粘连和结圈等烧成等问题的产生。
此外，覆膜剂中添加的水玻璃等组分，易于与骨料基体形成稳定的结合，进而有利于提高瓷化骨料产品的强度。

具体实施方式
应该指出，以下详细说明都是例示性的，旨在对本发明提供进一步的说明。除非另有指明，本发明使用的所有技术和科学术语具有与本发明所属技术领域的普通技术人员通常理解的相同含义。
第一方面，本发明提供了一种瓷化骨料素坯防掉粉覆膜剂，其组分包括水玻璃、高粘剂凹土、高液限黏土和水。
本发明以水玻璃、高粘剂凹土、高液限黏土为基础材料，制成悬浮性能稳定、易于雾化的溶液，经过特殊设计的与骨料生产线契合的雾化装置，在骨料素坯表面裹覆一层高强度裹覆膜。该裹覆膜喷涂到骨料表面后，会与骨料表层发生结合反应，形成稳定的结合过渡层及表面裹覆膜层，该裹覆膜层和过渡层会随着骨料水份的流失，硬度提高，最终形成耐磨度远高于普通骨料素坯的表面层。
水玻璃是由碳酸钠跟石英通过高温熔解成熔块，然后用高温高压水形成一种半透明的溶液，水玻璃在该裹覆膜喷涂浆料中，主要起到电解质稀释的作用，能够改善喷涂浆料的流动性能，而且不影响喷涂浆料的强度。
高粘剂凹土是利用稀有天然非金属矿-凹凸棒石粘土(Attapulgite Clay)经过浸泡、研磨、脱水、表面活化、粉碎包裹、调配等工艺经科学配方和特殊加工工艺制成的一种高粘度产品，高粘剂凹土是一种天然的水合镁铝硅酸盐，具有独特的三维空间链式结构，及特殊的针、棒纤维状晶体形态。在该裹覆膜喷涂浆料中，主要应用其具有的高粘结性,优异的悬浮性和胶体触变性,耐温,耐火,耐腐蚀,在工作介质中具有惰性和稳定性等特性。
高液限黏土是粘土的一种，高液限粘土从地质成因上属于坡残积物，岩性为含砾石粘土，砾石含量多在20％-30％，为火山碎屑岩的风化产物，多呈红棕色。该黏土具有非常特殊的物理力学性质，如含水量平均值56％、干密度13.6kN/m、湿密度l5.2kN/m、液限77、塑限39、无侧限抗压强度34kPa、最优含水量38％、最大干密度13.9kN/m，土的液限值越高，硬度越大，稳定性越好，从而可以为裹覆喷涂膜提供干燥后的表面硬度。高液限土通常含有大量的蒙脱石、伊利石、高岭石等黏土成分，均为瓷化材料必须的黏土成分，而且可以提供比瓷化骨料基体高的硅铝含量，从而可以形成比骨料基体高的耐温度和烧成后强度。
在一些实施例中，覆膜剂，由以下重量份的组分组成：水玻璃 2.5-3.5份、高粘剂凹土10-12份、高液限黏土8-10份和水75-80份。
第二方面，本发明提供一种瓷化骨料素坯防掉粉覆膜系统，包括：骨料整形机、浆料池和喷雾装置，其中，
所述喷雾装置包括输浆装置和至少一个喷头，喷头安装于输浆装置的输出端，输浆装置的输入端通过浆料泵与浆料池连通；
所述喷头设置于骨料整形机的整形腔的尾部。
在一些实施例中，所述喷雾装置为摇摆喷雾装置，包括驱动机构、刚性输浆管道和若干喷头，刚性输浆管道的一端与所述驱动机构连接，沿其轴向设置所述若干喷头，刚性输浆管道通过管路与浆料池连接。

刚性输浆管道的端部套设于驱动套管内部，其外壁设置有与所述拨片配合的凸出件；
拨片在承重大于设定值时可发生形变，与凸出件脱离。
实际工作中，驱动装置通过皮带等传动件带动带轮转动，进而带动驱动套管转动，当驱动套管上的拨片转至与刚性输浆管道上的凸出件接触后，会通过凸出件带动刚性输浆管道旋转，由于刚性输浆管道的下端设置喷头组件，重量较大，当刚性输浆管道旋转时，对拨片施加的压力变大，大到一定程度时，拨片形变(拨片可以由耐高温且耐 磨的弹性材料制备；也可以通过铰接的方式设置于驱动套筒的内壁上，且拨片的侧面通过复位弹簧与驱动套筒内壁连接)，与凸出件脱离，刚性输浆管道在重力作用下回旋，进而发生摇摆。
可以通过调节驱动套管的旋转频率调节喷头的摇摆频率。
摇摆喷雾装置的喷浆区域面积更大，更有利于浆料均匀分布在骨料素坯的表面。
更进一步的，还包括支架，所示支架上设置有至少两个弧形支撑区域，弧形支撑区域与刚性输浆管道配合设置。
支架本体延伸出骨料整形机，利用弧形支撑区域对刚性输浆管道进行支撑，以保证喷料过程的稳定性。
在一些实施例中，还包括回收罩，回收罩设置于喷头的上方，且通过管路与回收池连接。
进一步的，所述回收池与浆料池连通。
第三方面，本发明提供一种瓷化骨料素坯防掉粉覆膜方法，包括如下步骤：
将水玻璃、高粘剂凹土、高液限黏土和水按设定比例混合后，高速离散搅拌，制成稳定浆液；
将制备得到的稳定的浆液均匀附着于瓷化骨料素坯的表面，形成覆膜。
在一些实施例中，所述浆液通过喷淋的方式附着于瓷化骨料素坯的表面。
进一步的，浆液喷淋过程中，瓷化骨料素坯不断翻滚。
进一步的，瓷化骨料素坯上覆膜后，还包括将其进行干燥的步骤。
