Description

Technical Field

[0001] The utility model relates to the technical field of concrete recycling, and more specifically to a concrete recycling device for a construction site. Background Art

[0002] During construction, concrete waste is prone to falling and piling up at the bottom of the construction object. After being collected and crushed, it still has good recycling performance.

[0003] After searching, the existing patent number is CN212790099U, which is a concrete sand and gravel sewage recovery device. The device can screen out the sand and gravel with larger particles in the concrete through the feed box, and then screen out the sand and gravel with smaller particles through the filter plate. The remaining sewage is precipitated in the recovery box, and then the precipitate is effectively discharged from the recovery box through the sewage discharge mechanism, thereby effectively improving the recovery efficiency of concrete sand and gravel sewage; by fixing the filter plate with the support spring and continuously vibrating the filter plate through the vibration mechanism, the sand and gravel on the filter plate are effectively discharged, and the filter plate is prevented from being blocked, thereby effectively ensuring the sewage treatment effect; by rotating the leveling feet, the recovery box can be effectively leveled to ensure its horizontality when used on the construction site, which is suitable for sites with complex feet to ensure the normal operation of the recovery box.

[0004] The collected compacted concrete waste is easily accompanied by dust during the process of being put into the crusher and crushed. Although some crushers are equipped with exhaust cleaning components on the surface, the installation position of the dust hood and the pipeline arrangement of the dust pipe are not good, which affects the subsequent purification performance. Therefore, we proposed a construction site concrete recycling device to solve the above problems. Utility Model Content
