Description

Technical Field

[0001] This utility model relates to the field of waste concrete recycling technology, specifically a waste concrete aggregate screening and recycling device. Background Technology

[0002] Waste concrete recycling is the process of processing and reusing concrete blocks from construction waste. Among them, waste concrete aggregate screening and recycling involves processing waste concrete through crushing, screening and other processes to separate recycled aggregates of different particle sizes, so as to realize resource utilization. This technology can reduce the pressure of construction waste landfill, reduce the environmental impact of natural aggregate mining, and provide sustainable alternative materials for engineering construction.

[0003] Chinese patent discloses a waste concrete aggregate recycling device (authorization announcement number CN221832438U). This patented technology connects a second fixed block to a first fixed block via a telescopic rod, supported by a strong spring tension. This allows for some movement between the first and second crushing rollers, preventing larger pieces of concrete aggregate from getting stuck. This solves the problem of needing to stop the machine to remove the aggregate when it gets stuck between the crushing rollers, thus improving the production efficiency of the waste concrete aggregate recycling device. However, the aforementioned method of crushing waste concrete aggregate by rolling with crushing rollers results in low crushing efficiency and low completeness of crushing, which is detrimental to the completeness of cleaning the concrete residue from the waste concrete aggregate and the subsequent recycling and reuse of the waste concrete aggregate. Furthermore, the screen is stationary during the screening process, which is detrimental to the screening effect and recycling efficiency of the waste concrete aggregate. Therefore, those skilled in the art have provided a waste concrete aggregate screening and recycling device to solve the problems mentioned in the background art. Utility Model Content
