Municipal waste separation system

Abstract

The invention relates to a municipal waste separation system. The municipal waste separation system is characterized by comprising a feeding machine, a secondary rotary screen, a first buffer bin, a second buffer bin, a first spiral conveyer, a second spiral conveyer, a gravity separator, a first sorting belt, a second sorting belt, a first magnetic separation device, a second magnetic separationdevice, a third magnetic separation device, a first vortex separation device, a second vortex separation device, an inert material storage hall, a resource description framework (RDF) storage hall, alarge-inclination-angle belt machine, a vibrating screen and a crushing machine. The separation system has high sorting efficiency, and can effectively separate combustible substances, insert components, ferrous metal / non-ferrous metal, and harmful substances in the pre-crushed and dried municipal waste to facilitate subsequent comprehensive utilization. The separation process is totally closed,remote operation and control is performed by using a computer, waste is not required to be directly contacted, the working environment of workers is improved, mechanization and automation are realized, and efficiency is improved.

Description

technical field [0001] The invention relates to a municipal garbage sorting system, in particular to a municipal garbage sorting system which has been pre-crushed and dried. Background technique [0002] The treatment and utilization of municipal waste "harmless, reduced, and resourceful" is a worldwide issue. At present, the centralized treatment methods of urban and rural municipal waste in my country mainly include landfill, composting, and incineration. The landfill method occupies a large area and has a low degree of waste reduction. It requires anti-seepage treatment, and a biogas recovery and leachate treatment plant must be built, which is likely to pollute groundwater and surrounding air. The composting method is suitable for treating waste containing a lot of perishable organic matter, and can realize the comprehensive utilization of some resources, but the quality of composting is not easy to control, and the harmful components often exceed the standard. Waste i...

Problems solved by technology

If the existing sorting machinery is difficult to sort these wet and sticky garbage, if it is unavoidable, we can only choose simple screening and manual sorting operations

There are many shortcomings in this garbage disposal method: the working environment of the sorting workers is harsh, and the dust and odor cause great harm to the physical and mental health of the operators; Low efficiency, difficult to guarantee sorting quality
