[0002] Due to the insufficient capacity of supporting garbage treatment facilities in the process of accelerated urbanization in my country, my country has begun to widely use landfill to solve the problem of dealing with urban domestic garbage since the 1970s. As a result, there are currently many informal garbage landfills in my country, which have caused serious pollution to the groundwater, surface water and soil environment in the dumping area, becoming one of the factors restricting the development of cities in my country. Therefore, there is an urgent need to excavate these landfill garbage, screen them, and utilize them as resources.

[0003] Stale garbage, also known as mineral garbage, refers to urban domestic garbage that has been piled up in landfills or for many years. In recent years, the problem of stale garbage storage has become increasingly prominent. The composition of stale garbage is complex. Traditional garbage screening equipment is difficult to systematically classify stale garbage and systematically separate construction waste, plastic domestic garbage, and textile domestic garbage. In addition, the screening of the oversize material is not thorough, resulting in an increase in the subsequent oversize material processing cost. Therefore, this technical solution is specially proposed for improvement. Utility Model Content

[0017] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] See also Figures 1 to 4 The embodiment of the utility model discloses a stale garbage screening production line, including a chain plate feeder 1 arranged at the raw material pile. The arrangement of the chain plate feeder 1 ensures the uniform supply of raw materials. The output end of the chain plate feeder 1 is directly connected to the No. 1 conveyor 2. The No. 1 conveyor 2 uniformly conveys the raw materials to the integrated screening machine 3. The integrated screening machine 3 can perform preliminary separation according to the diameter of the materials, and guide large-diameter materials (such as construction waste fragments) and small-diameter materials (such as plastic fragments, textile fragments, etc.) to different conveying paths respectively, which is convenient for the next step of sorting.

[0019] The output end of the integrated screening machine 3 is equipped with two conveyors. The No. 2 conveyor 4 is responsible for conveying large-diameter materials, which is convenient for subsequent classification processing and resource utilization. The No. 3 conveyor 5 is located at the bottom of the integrated screening machine 3, which is specifically used to collect and convey small-diameter materials, ensuring the continuity and efficiency of the screening process. The output end of the No. 3 conveyor 5 is connected to the No. 4 conveyor 6. As a transfer conveying device, the No. 4 conveyor 6 further conveys the small-diameter materials to the first drum screen 7. The first drum screen 7 uses the rolling screening principle to further divide the materials into large-diameter and small-diameter parts. The No. 5 conveyor 15 is arranged at the tail of the first drum screen 7, and the No. 6 conveyor 8 is arranged below the first drum screen 7. The materials on the No. 5 conveyor 15 are mostly heavier impurities or larger pieces of residue, while the No. 6 conveyor 8 is mainly transported to materials with smaller diameters such as humus soil. The humus soil and other materials with smaller diameters are separated by the first drum screen 7, which greatly improves the subsequent screening effect, facilitates the screening and collection of humus soil, and improves the use effect.

[0020] The output material of No. 6 conveyor 8 is sent to the second drum screen 11 through No. 7 conveyor 9 and No. 8 conveyor 10. This screening equipment is specially used for screening humus soil. The screened humus soil is collected by No. 10 conveyor 12 and No. 11 conveyor 13 arranged on the second drum screen 11, providing resources for subsequent soil improvement or agricultural utilization. No. 9 conveyor 14 is arranged at the tail position of the second drum screen 11 to transport the screened material with a slightly larger diameter to No. 5 conveyor 15. The materials of the first drum screen 7 and the second drum screen 11 are transported by No. 5 conveyor 15 to improve the screening effect. In order to improve the screening efficiency and product quality, the conveyor of No. 5 conveyor 15 An iron removal device 16 is installed on the path to remove metal impurities in the material. In addition, an air separator 17 is also set at the output end of the No. 5 conveyor 15. Using the principle of aerodynamics, the material is further divided into two groups of different diameters according to the weight and shape differences of the material, and output by the No. 12 conveyor 18 and the No. 13 conveyor 19 respectively, in preparation for subsequent fine processing or resource utilization. It not only realizes the efficient and systematic classification of stale garbage, but also effectively improves the efficiency and quality of resource utilization through multi-stage screening and fine processing. It is easy to operate and provides a practical technical solution to solve the problem of stale garbage treatment in the process of urbanization in my country.
