Description

A device for on-site screening and collection of engineering waste residues

Technical Field

The utility model relates to the technical field of engineering waste residue treatment, in particular to an on-site screening and collecting device for engineering waste residue.

Background Art

The long-term storage of solid waste such as construction waste not only occupies a large amount of land, but also causes serious pollution and harm to the water system and the atmosphere. In order to prevent the construction waste from exceeding the metal content of the land, the construction waste needs to be recycled and processed for energy reuse after it is produced. Before smelting the waste, an on-site screening and collection device for construction waste is needed to screen the construction waste.

However, it is difficult to classify engineering waste slag according to its particle size due to the existing screening and collection devices. In order to facilitate the subsequent smelting of the waste slag, the larger waste slag needs to be broken up after screening. The waste slag may be blocked in the screening holes during the screening process, resulting in the screening holes being unable to screen the waste slag normally. In this regard, we propose an on-site screening and collection device for engineering waste slag to solve the above problems.
