Facing the status quo of garbage siege, it is urgent to speed up the disposal of domestic garbage. In the past, the main methods of domestic waste treatment in my country were landfill and incineration. Landfill treatment is to bury garbage directly into the ground, which will leave a large amount of harmful substances and pollute groundwater resources; while incineration treatment is prone to produce dioxins, which are highly toxic substances that are harmful to the ecological environment and human health. Great harm. Sorting domestic waste is a revolution to the above-mentioned traditional treatment methods. It is a scientific and sustainable treatment method that can greatly reduce the amount of waste, improve the ecological environment, and turn waste into treasure. Conducive to garbage recycling. Automatic garbage sorting machine technology and equipment play an important role in the process of garbage sorting and recycling.

Common household garbage is usually crushed by a household garbage shredder, and then sorted. The sorting technology mainly includes screening, gravity sorting, buoyancy sorting, magnetic sorting, electric sorting, etc.

1.3D screening method

Screening is to vibrate mixed garbage with different particle sizes through a sieve to pass garbage particles with a diameter smaller than the sieve hole through the sieve surface, and large garbage with a diameter larger than the sieve hole will remain on the sieve, so as to achieve a life of different diameters. How to sort garbage.

2. Gravity sorting

Gravity sorting is based on the different densities of different components in domestic waste. Through the combined action of gravity, media power and mechanical force, domestic waste is layered and separated to obtain products of different densities. According to the different sorting media, the gravity sorting of domestic waste can be divided into wind sorting, jig sorting, shaking table sorting and heavy medium sorting.

3. Buoyancy sorting

Buoyancy separation is mainly carried out by treatment with liquids and surface treatment agents. Due to the different surface properties of the components of domestic garbage and different adsorption capacity, some garbage can float on the surface of the liquid, and some are at the bottom of the liquid, so as to achieve the purpose of sorting.

4. Magnetic sorting

Magnetic separation is a method to achieve separation according to the different magnetic properties of each component of domestic waste. After the domestic waste is fed into the magnetic separator, the magnetic particles in the domestic waste are magnetized by the attraction of the magnetic field, and are adsorbed on the cylinder of the magnetic separator. Non-magnetic particles are discharged together with other wastes.

5. Power sorting

Electric power sorting is a method of sorting using the different electrical properties of the components in the household waste in the electric field. Most domestic waste is semiconductors.
