Description

Technical Field

[0001] The utility model relates to the technical field of concrete recycling, in particular to a waste concrete recycling and separation device. Background Art

[0002] Waste concrete refers to discarded concrete blocks. For example, after the dismantling of a building, high-quality crushed and screened concrete blocks and silt can be used as recycled concrete. Waste concrete blocks are not only high-quality concrete aggregates, but also have many advantages in using waste concrete blocks as aggregates. For example, after the dismantling of a building, high-quality crushed and screened concrete blocks and silt can be used as recycled coarse and fine aggregates for concrete. A large amount of micro powder can be directly used as raw materials for cement. Concrete prepared with recycled cement and recycled aggregates can enter the next cycle. In the entire cycle, waste is discharged at zero rate.

[0003] Concrete, cement and other wastes in construction waste can be used to replace gravel to produce dozens of environmentally friendly bricks such as lawn bricks, square bricks, blind hole bricks, permeable bricks, partition bricks, modular bricks, insulation bricks, block bricks, etc. after reasonable crushing, screening and grinding.

[0004] However, when screening after crushing, the existing equipment mostly directly cleans out the large pieces of concrete that are screened out and accumulated in the screening component, but cannot simultaneously process them so that they can pass through the screening smoothly; for example, the prior art of a waste concrete separation device for concrete processing (Chinese patent, authorization announcement number CN218282688U) records that "when the screening bars are away from each other, the waste concrete that does not pass through the gaps between the mutually staggered screening bars can be screened out from the discharge port along the screening bars, thereby separating the waste concrete blocks." This also means that the waste concrete that does not pass through the screening is directly screened out and cannot be processed synchronously so that it can pass through the screening smoothly. Therefore, a waste concrete recovery and separation device is specially proposed. Utility Model Content
