Garbage sorting technology is a crucial theoretical foundation for garbage classification. Sorting technology contains reasonable and effective advanced technical thinking. After a large number of experimental results and operational use, it can better explore garbage treatment equipment that is more suitable for China's market. So continuously improving and perfecting the technical level of garbage sorting and treatment equipment is more beneficial to the advancement of garbage sorting technology in China and to change the harmony between our living environment and society. This is a long-term livelihood plan that benefits the country and the people, and it is more necessary to receive support and promotion from all sectors of society. Below, we will briefly introduce the sorting technology of garbage sorting equipment.

 

1. Wind selection

 

The basic principle of a wind powered air separator in a household waste treatment project is that the airflow carries lighter materials upwards or horizontally towards farther places, while heavier materials sink and settle due to the inability of the rising airflow to move them, or are thrown closer in the horizontal direction due to inertia. The entire process of wind power selection is mainly based on the settling law of various solid particles in the air, and is mainly used to screen recyclable components such as waste paper and plastic.

 

2. Magnetic Separation

 

Magnetic separation technology can be applied to the classification and management of mineral resources in garbage. After entering the sorting area of the magnetic separator, materials will be subjected to the effects of magnetic and mechanical forces (gravity, centrifugal force, water flow force, etc.). Materials with different magnetic properties will experience different magnetic effects and operate in different ways. Due to the different ways in which mineral particles operate, magnetic and non-magnetic materials, or materials with strong and weak magnetism, can be obtained.

 

3. Bounce sorting

 

Bouncing sorting machine is a machine equipment specially designed for sorting inorganic particles in garbage after rough crushing, with separation function. This device utilizes the characteristics of crushed waste materials, and the conveyor belt is designed to bounce and separate inorganic particles or other hard particles at the same time as transporting the materials. The separated particles operate in reverse with the transported materials, thereby achieving the purpose of sorting in domestic waste treatment engineering. Bounce sorting mainly involves selecting components such as batteries, porcelain, and bricks.

 

4. Density sorting

 

Density sorting is mainly based on the density of materials, sorting and classifying garbage with different density values.

 

5. Automatic sorting

 

Combined with mechanical equipment, intelligent control, microorganism and other methods, the automatic waste sorting technology can classify the mixed domestic waste into super large waste, ferrous metal, non-ferrous metal, plastic products and foam plastic materials, soft strips, perishable organic compounds, non perishable organic compounds, brick glass, sand, waste batteries, landfill and other materials. The recycling rate of waste can reach more than 85%, and the waste water, dust, bacteria and viruses in the treatment process can be reasonably and effectively treated and effectively controlled.

 

Garbage sorting technology is the front-end technology of household waste treatment engineering. Compared with the reuse of resources and the subsequent treatment of garbage, it is an indispensable process.
