Description
本发明属于环境领域，特别涉及一种小区厨余垃圾收集及预处理系统。
厨余垃圾是家庭、宾馆、饭店等饮食单位抛弃的剩余饭菜的统称。目前世界各国绝大部分城市垃圾中约40％为厨余垃圾，主要包括主食(米、饭、馒头、面条等)、蔬菜、水果及果皮、肉骨、蛋壳、鱼虾、茶叶及咖啡残渣、豆制品、动植物油、残羹剩饭及下脚料等。厨余垃圾因其有机质和水分含量大、易腐败、热值低等特点，难于直接填埋和焚烧处理，而好氧堆肥技术既可实现厨余垃圾的无害化和减量化，又可生产有机肥作为农用，是处理厨余垃圾的有效方式。由于我国城市垃圾的收集以混合收集为主、分选效果差，垃圾中所含玻璃、塑料、碎石块等杂质不会在堆肥过程中被分解，导致所得肥料质量差，病原微生物未得到彻底消除，肥料中重金属含量也高，产业化前途一片黯淡。因此，为真正实现厨余垃圾资源化，厨余垃圾从源头分类至关重要，智能厨余垃圾收集装置需要应运而生。
目前，在小区内，垃圾分类才刚刚开始施行，厨余垃圾由于具有多种易被微生物利用的物质，因此易散发较大的味道，特别是在夏天小区内集中放置，严重影响了生活环境，因此亟需对小区内短暂收集的厨余垃圾进行预处理。
技术问题：为了解决现有技术的缺陷，本发明提供了一种小区厨余垃圾收集及预处理系统。
技术解决方案：本发明提供的一种小区厨余垃圾收集及预处理系统，包括自上而下依次设置的收集装置、粉碎装置、离心装置，还包括与离心装置连接的废液预处理装置和固体干燥装置，所述废液预处理装置与废液罐连接，所述干燥装置与固体收集装置连接；所述固体收集装置用于收集固体厨余垃圾；所述粉碎装置用于将厨余垃圾粉碎成预定大小；所述离心装置用于将厨余垃圾的固液分离；所述废液预处理装置上设有处理剂投加装置，用于对废液进行预处理； 所述干燥装置用于将固体垃圾干燥，并将干燥的固体垃圾送至收集装置。
作为改进，所述收集装置内的收集口为感应式收集口，当人体接近收集口时，自动开启。
作为改进，所述粉碎装置的转速为20-60转/分，粉碎装置内设有称重装置，根据重量自动调节转速。
作为改进，所述离心装置包括外筒和内筒，内筒底部为固体出口，内筒侧壁为多孔结构，外筒底部设有废液出口。
作为改进，所述处理剂包括去味剂和/或混合菌。
作为改进，所述干燥装置为烘箱，其外部设有吸味剂。
作为改进，所述固体收集装置为自动打包机。
有益效果：本发明提供的小区厨余垃圾收集及预处理系统可在小区内实现自动预处理，处理后的垃圾可再运输到处理厂进行深加工，不仅避免了短期存放散发异味，影响人们的生活环境，而且方便了处理厂进一步处理。
