Description

Technical Field

[0001] The invention belongs to the field of garbage screening, and more specifically, particularly relates to a stale garbage screening and processing device. Background Art

[0002] Due to long-term accumulation and landfill, stale garbage contains a large number of different components, such as humus, combustibles, inorganic substances and ferromagnetic substances. These components are very different in nature, form and use. If they are directly mixed, it will not only reduce the treatment efficiency, but also increase the treatment cost, and may even cause secondary pollution to the environment. Through screening treatment, the different components in stale garbage can be effectively separated, which provides convenience for subsequent resource utilization and harmless disposal.

[0003] The prior art still has the following problems:

[0004] First, the existing screening mechanism is easily blocked by the screening objects due to the size of the screening holes. Once blockage occurs, the garbage cannot pass through the screening holes smoothly for effective separation, which directly leads to a significant reduction in the quality of garbage screening. For example, the fine materials that should be separated may be retained in areas where they should not be retained due to blockage, affecting the subsequent separate treatment of garbage of different particle sizes. In addition, in terms of efficiency, the screening speed will be significantly slowed down after blockage, and it may even be necessary to frequently shut down to clean up the blockage, which seriously slows down the entire garbage screening process.

[0005] Second, the existing screening machines are unable to handle blockages, resulting in a failure to promptly clear the blockages. This will cause the effective screening area of ​​the screening holes to continue to decrease, further exacerbating the reduction in screening efficiency. The material separation work that was originally able to proceed normally will become increasingly slow, seriously affecting the progress of the entire production process.
