Description

Technical Field

[0001] The utility model relates to the technical field of solid waste treatment, in particular to a vibration type multi-stage solid waste pretreatment screening device. Background Art

[0002] Solid waste treatment, full name solid waste disposal, usually refers to the process of converting solid waste into materials suitable for transportation, storage, utilization or disposal by physical, chemical, biological, physicochemical and biochemical methods. The goal of solid waste treatment is to make it harmless, reduce its volume and recycle it into resources. Among them, construction waste accounts for the majority of solid waste, and construction waste is often used in building fill. Among them, the existing construction waste is often not distinguished by size and type when transported before treatment, and is uniformly recycled and transported.

[0003] When processing construction waste, it is generally necessary to separate and select large pieces of construction waste from small pieces of construction waste, and then crush the large pieces containing useful resources, and then manually sort the crushed and originally screened small pieces. Large useful resources are easy to select, but relatively small useful resources are more time-consuming and labor-intensive to sort manually. In addition, the iron products in the garbage are not easy to handle, resulting in a waste of resources. In addition, the sorting efficiency is very low, and the site required for sorting is relatively large, which cannot meet the use requirements. Utility Model Content
