The traditional treatment of stale garbage adopts open treatment, which causes serious secondary pollution to the surrounding environment due to dust and odor diffusion during the process. Therefore, in order to solve the above problems, it is necessary to provide a system for treating stale garbage, which can solve the pollution caused by improper disposal of stale garbage to the surrounding environment and achieve the recycling and reuse of earth resources. Including a feeding machine, which is used to transport stale garbage; Vibration screen is used to screen aged garbage; The drum screening machine is used to further screen aged garbage; The enclosed air separator screens and classifies aged garbage.

The equipment for handling stale garbage includes a feeding machine, a vibrating screen, a drum screening machine, and a closed air separator. The stale garbage is transported to the vibrating screen through a conveyor belt connected to the feeding machine. Under the vibration of the vibrating screen, bricks and tiles are sorted out through the vibrating screen. After collection, they are directly buried. It should be noted that there is also a manual sorting platform on the conveyor belt between the feeding machine and the vibrating screen machine. Large items are sorted out manually on the conveyor belt through the manual sorting platform, and bagged garbage mixed in the garbage is torn open. The aged garbage sorted out by the vibrating screen is sent into the drum screening machine through the conveyor belt. The drum screening machine divides the aged garbage into sieved and undersized materials according to the size of the sieve plate aperture. The undersized materials can be used as nutrient soil for landscaping, and the undersized materials are sent into the comprehensive air sorting machine through the conveyor belt. The closed air sorting machine includes a box body. The upper right side of the box body is equipped with a feeding port, which is connected to a conveyor belt. The lower sides of both ends of the box body are equipped with a drum for holding the first collection box and the second collection box. The lower end of the feeding port is equipped with a first level conveyor belt, and the lower end of the drum is equipped with a second level conveyor belt. The connection between the first level conveyor belt and the second level conveyor belt is located below the first level conveyor belt. There is a third collection box. The box of the stale garbage treatment equipment is located below the feed inlet and has a first air inlet and a second air inlet. There is also a third air inlet under the first conveyor belt. The first air inlet, the second air inlet, and the third air inlet are all equipped with a first fan, a second fan, and a third fan. The other end of the box is equipped with a induced draft fan.
