Description

Technical Field

[0001] The invention relates to the technical field of waste concrete recycling, and in particular to waste concrete recycling and crushing equipment for construction engineering. Background Art

[0002] Waste concrete refers to discarded concrete blocks. For example, after the disintegration 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 disintegration of a building, high-quality crushed and screened concrete blocks and silt can be used as recycled concrete, coarse and fine aggregates, and a large amount of micropowder can be directly used as raw materials for cement. Concrete prepared with recycled cement and recycled aggregates can enter the next cycle. During the entire cycle, zero waste is discharged. Concrete, cement and other wastes in construction waste can be used to replace gravel after reasonable crushing, screening and crushing to produce lawn bricks, square bricks, blind hole bricks, permeable bricks, partition bricks, modular bricks, insulation bricks, block bricks and dozens of other environmentally friendly bricks.

[0003] Based on the existing technology, a complete set of concrete crushing and recycling production line is mainly composed of main equipment such as reciprocating feeder, concrete crusher, bucket wheel sand washing machine, belt conveyor, etc. However, the concrete recycling equipment in the existing technology does not process the dust generated when the waste concrete is crushed during use, causing the dust to float in the external environment, which is environmentally friendly. At the same time, additional equipment is required to wash the waste concrete, which has low practicality. Summary of the invention
