本发明主要由预混合器1、聚合反应器2、布料装置3、切割装置4、 粉碎机5、输送机6和包装机7组成，通过将原料投入预混合器1中进行混合，然后在送料泵8及布料装置3的作用下，将预混合器1中的液体物料均匀的喷洒在聚合反应器2中的皮带输送组件15上，在皮带输送组件15的作用下首先进入聚合反应器2的高温区11中进行缩聚反应，然后在聚合反应器2的低温区12中冷却固化，经过冷却固化后的产品在切割装置4的作用下从皮带输送组件15上刮落，脱落后的产品在输送机6的作用下输送至粉碎机5中进行粉碎，然后通过输送机6将粉碎后的聚合磷酸盐送至料斗34中进行暂存，并使用包装机7实现对产品的包装；能够实现对产品的自动化生产，其具有自动化程度高的优点。
其中，预混合器1为SD型静态混合器；能够使得投入的物料能够混合得更加的均匀。
在实际的使用中，预混合器还可以为SMX型、SMV型、或SK型静态混合器。
进一步优化，在本实施例中，布料装置3为摆动布料器，这样能够使其平喷洒在皮带输送组件15上时厚度更加均匀，使得反应后形成的产品质量更加统一。
其中，加热组件13包括设置在高温区11内以天然气作燃料的若干U型辐射加热管16，U型辐射加热管16上间隔布置有多个传热翅片17；在实际的使用中，以天然气作为燃料，使用连续控制的方式确保U型辐射加热管16表面温度均匀，同时，降低烟气的排放。
进一步优化，U型辐射加热管16设置在高温区11内外壳9的左右两侧壁上，同一侧相邻U型辐射加热管16间距为1-2m；这样设置能够提高热量传递效率。
进一步优化，加热组件13还包括设置在高温区11两侧的循环轴流 风机18；这样，在实际的使用中，通过设置的循环轴流风机18能够使得高温区11内的热空气温度分布更加均匀，使得物料受热效果更佳，保证其进行正常的反应。
其中冷却组件14包括冷凝器19、转轮除湿机20和引风机21，引风机21设置在外壳9顶部，冷凝器19与转轮除湿机20连接，转轮除湿机20与引风机21连接；在低温区12内其中一侧面设置有第一循环轴流风机18。
这样，物料在低温区12采用空气进行冷却固化，外部空气经冷凝器19后进入转轮除湿机20，除湿后再进入到聚合反应器2的低温冷却段，空气经转轮除湿后湿度控制在12％以下。同时，在低温区12的一个侧面装有轴流循环风机，确保冷风均匀分布。
其中，粉碎机5为锤式JF型粉碎机5。
其中，输送机6为刮板式输送机6。
实施例二
本实施例是在实施例一的基础上进一步优化，在本实施例中，皮带输送组件15有多个，每一个皮带输送组件15均包括传送带22、第一传动轮23和第二传动轮24，传送带22缠绕在第一传动轮23和第二传动轮24上；多个皮带输送组件15从上至下依次设置；后一个皮带输送组件15的进料端超出前一个皮带输送组件15的进料端20-30cm；布料装置3与一驱动装置25连接，驱动装置25用于驱动布料装置3向上、向下、向左及向右移动；每一个皮带输送组件15均对应一个切割装置4。
其中，驱动装置25包括横向驱动组件26和安装在横向驱动组件26上的竖向驱动组件27，布料装置3设置在竖向驱动组件上；
横向驱动组件26用于驱动竖向驱动组件27及布料装置3左右移动；竖向驱动组件27用于驱动布料装置3上下移动。
其中，对横向驱动组件26具体结构做进一步说明：
横向驱动组件26包括支架28、安装在支架28上的丝杠29、滑动配设在丝杠29上的滑块30，滑块30上设置有导向孔，支架28上设置有导向杆31，导向孔与导向杆31相互配合，支架28上安装有电机32，电机32与丝杠29连接。
其中，竖向驱动组件27包括气缸33和与气缸33连接的气泵，气缸33的活动端与布料装置3连接，气缸33的固定端固定安装在滑块30上。
这样，在实际的使用中即可通过横向驱动组件26和竖向驱动组件27来调节布料装置3的位置，进而实现对不同的皮带输送组件15进行布料的目的，这样能够有效的提高聚合磷酸盐的合成效率。
其中，皮带输送组件15中皮带由聚四氟乙烯(PTFE)、聚醚醚酮(PEEK)、聚酰亚胺(PI)、玻璃纤维中的一种或多种复合而成。
进一步优化，采用玻璃纤维复合时，玻璃纤维的加入量为10％～40％。
