Large garbage treatment process and system

Abstract

The invention provides a large garbage treatment process and system. The process comprises the following steps: step 1, crushing large garbage; step 2, separating light materials from heavy materials;and step 3, sequentially separating iron metals, nonferrous metals and nonmetals from the heavy materials. The system is provided with a four-axis crusher, a winnowing machine, a magnetic separator,an eddy current separator and an electrostatic separator which are sequentially butted. According to the treatment process and system, the large garbage can be firstly crushed, the size of the large garbage is controlled to be a proper size, then the light materials and the heavy materials are separated, and then the iron metals, the nonferrous metals and the nonmetals are separated, so that separation of corresponding components can be effectively completed, and resource reutilization is realized.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a large-size garbage treatment process and system. Background technique [0002] With the rapid development of my country's economy, the rapid advancement of urbanization, and the improvement of people's living standards, the large-scale garbage generated in the process of housing decoration, relocation, and residents' waste furniture renewal is also increasing day by day. Oversized garbage refers to the weight over 5kg or the volume greater than 0.2m 3 Or waste with a length of more than 1m in one direction. This kind of garbage has a strong integrity and may be reused or disposed of after being broken. Due to the large size of bulky garbage, it is difficult for ordinary garbage trucks and transfer vehicles to operate, and subsequent processing after operation is also very troublesome. As the earth's resources continue to decrease, the resource utilization of bulky ...

AI Technical Summary

Problems solved by technology

[0004] 1. There are potential safety hazards: heat will be generated during the crushing process of materials. When the heat is concentrated to a certain value, the crushed materials (combustibles) can be ignited. If they cannot be disposed of in time, the entire production line will be ignited, causing a fire;

[0005] 2. High labor cost: the automation of the equipment is low, every link is manually operated, and there is no integrated control;

[0006] 3. Low degree of resource utilization: after crushing, the size of the material is large, and the next step of separation cannot be performed, or the separation is not obvious
