Description

Technical Field

[0001] The utility model relates to the technical field of solid waste fine material recovery, in particular to a solid waste fine material recovery screening device. Background Art

[0002] Solid waste fines generally refer to the construction waste dismantled from the original building during the construction process and the waste generated during the construction process. Because these wastes also contain coal gangue, fly ash, coal slag, blast furnace slag, steel slag and other solid wastes that have the components and properties required for building materials, these construction wastes can be recycled. During recycling, the fine materials generally need to be screened.

[0003] For the traditional method of screening fine materials, the fine materials are generally poured into the screen and filtered through the screen. However, when a large amount of fine materials is added to the screen at one time, the fine materials are easy to accumulate on the screen and cannot flow. In severe cases, the screen may be blocked, which not only increases the tediousness of manual removal, but also affects the filtration rate. Therefore, those skilled in the art provide a solid waste fine material recovery and screening device to solve the problems raised in the above background technology. Utility Model Content
