Abstract Aiming at the problems of high cost, large floor space and failure to meet the emission standards of the existing wet waste treatment device nearby, a new type of mechanical compressive wet waste treatment device is developed. Firstly, the functions and technical characteristics of the mechanical compressive wet waste treatment device were introduced. Then, the modular design of the mechanical compressive wet waste treatment device was carried out, which mainly included the lifting device, the conveyor belt sorting device, the crushing and dewatering device, the sewage treatment device and the briquetting device. Finally, the technical parameters of the mechanical compressive wet waste treatment device were designed and calculated, and its automatic control scheme was designed. The designed mechanical compressive wet waste treatment device integrated the traditional waste crusher and the press dehydrator to realize the efficient dehydration of the wet waste; through the treatment of the briquetting device, the compression of the waste residue was realized, which could effectively relieve the problems of tight capacity and secondary pollution in the waste transportation; by the treatment of the sewage treatment device, the recycling and reuse of sewage was realized. The mechanical compressive wet waste treatment device has the advantages of low cost, small volume, simple treatment process and less labor resource consumption. It is suitable for small and medium-sized waste collection stations that have implemented waste classification and collection, and has broad market prospects in the wet waste treatment industry.

机械压缩式湿垃圾处理装置设计
针对现有湿垃圾就近处理装置存在成本高、占地面积大以及垃圾处理后仍达不到排放标准等问题,研制了一款新型机械压缩式湿垃圾处理装置。首先,介绍了机械压缩式湿垃圾处理装置的功能和技术特点。然后,对机械压缩式湿垃圾处理装置进行模块化设计,主要包括提升装置、传送带分拣装置、破碎脱水装置、污水处理装置以及压块装置等。最后,对机械压缩式湿垃圾处理装置的技术参数进行设计计算,并对其自动控制方案进行设计。所设计的机械压缩式湿垃圾处理装置将传统的垃圾破碎机与压榨脱水机进行一体化设计,实现了湿垃圾的高效脱水;通过压块装置的处理,实现了垃圾碎渣的压缩,可有效缓解垃圾运输中的运力紧张、二次污染等问题;经污水处理装置的处理,实现了污水的循环再利用。机械压缩式湿垃圾处理装置具有成本低、体积小、处理流程简洁和耗费人力资源少等优势,适用于已实施垃圾分类收集的中小型垃圾收集站,在湿垃圾处理行业中具备广阔的市场前景。
