Description

一种高效纸塑分离筛选机 技术领域
本发明涉及资源再利用领域，特别涉及一种高效纸塑分离筛选机。
背景技术
目前，国内在垃圾处理和资源再利用方面还比较落后，尤其是在纸塑包装类行业，资源的回收再利用率比较低。现在的纸塑分离工艺主要通过碎浆机碎浆，纸塑复合材料在碎浆机的搅拌作用下，使纸纤维和塑料得到润张和脱离，然后把部分脱离的纸纤维排掉，再把带有大量纸纤维的塑料排到圆筒筛、滤水池、杂质分离机等进行脱水清洗，最后打包卖给塑料回收厂家。这种回收工艺存在的问题是：产能很低，塑料容易缠绕、分离不彻底、清洗不干净，需要二次加化学药品清洗，纸纤维回收率低，人工劳动强度大，耗能较高。
发明内容
本发明为了弥补现有技术的缺陷，提高纸塑复合材料的回收再利用，通过研究纸塑复合材料的特性、总结各类复合材料的分离筛选经验，提供了一种针对纸塑复合材料的高效纸塑分离筛选机。
本发明是通过如下技术方案实现的：
一种高效纸塑分离筛选机，包括两侧托辊、位于托辊之间的滚筒本体、电机以及传动机构，所述滚筒本体由转筒及外罩组成，其特征在于：所述转筒的一端为进料口，另一端为出料口，所述转筒内部均匀分布有若干梅花阻料板，转筒的内壁上均匀安装有若干刮料板，所述转筒的内安装有筛网，转筒的底部设有集浆池，所述电机连接减速机，减速机通过齿轮组带动转筒运动。
所述进料口的上方与高压喷水管连接，一方面高压喷水管可以对物料进行喷淋清洗，另一方面未脱离的纸纤维在转筒内进行充分的摔打剥离，得到充分的清洗。
所述出料口与转筒之间通过锥度螺旋管连接，能够均匀的将洗干净后的塑料输送出设备。
所述刮料板为V型刮料板，能够将物料全部刮起，均匀下落，便于清洗。
所述齿轮组包括套置在转筒外部的被动齿轮、与被动齿轮啮合的小齿轮，所述小齿轮通过对轮与减速机连接，电机通过减速机、对轮、小齿轮带动被动齿轮转动，从而使得转筒转动。
所述减速机为硬齿面减速机。
本发明的有益效果是：本发明的高效纸塑分离筛选机，结构设计合理，能使纸塑混合物料得到彻底的清洗和分离，提高了分离效率、同时提高了塑料的纯净度和纤维的回收率，无需再进行二次清洗，降低了劳动强度和耗能。
