Crushing type concrete recycling device

Abstract

The invention discloses a crushing type concrete recycling device, and belongs to the field of concrete recycling. The crushing type concrete recycling device comprises a box body; limiting plates arerespectively and fixedly arranged at the top end and the bottom end of an inner cavity of the box body; the middle of the front surface on one side of the box body is provided with round holes; the middles of the back surfaces of the two sides of the box body are respectively provided with sliding grooves; rolling shafts are respectively and movably connected with the interiors of the two slidinggrooves and the interiors of the round holes in a sleeving mode; threaded holes are respectively formed in the middle of the back surfaces of inner cavities of the two sliding grooves; one ends of the two rolling shafts both penetrate through and extend to the outside of the box body and are respectively and fixedly connected with spur gears in a sleeving mode; external teeth of the two spur gears are engaged with each other; and two ends of one of the rolling shafts are respectively and movably connected with movable blocks positioned in the two sliding grooves in a sleeving mode. The crushing type concrete recycling device is simple in structure and convenient to use, can drop due to the movement of one crushing tool rest, and prevents a waste concrete grinding and recycling recovery device from being blocked.

Description

technical field [0001] The invention relates to the technical field of concrete recovery, in particular to a broken concrete recovery device. Background technique [0002] Concrete, abbreviated as "concrete", refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. Generally speaking, the term concrete refers to cement as cementing material, sand and stone as aggregate, mixed with water (with or without admixtures and admixtures) in a certain proportion, and obtained by stirring, molding and curing. Cement concrete, also known as ordinary concrete. [0003] The service life of concrete is generally 50-60 years. During the renovation of rural housing, the demolition of waste concrete from old buildings cannot be ignored. Waste concrete blocks are not only high-quality concrete aggregates, but there are many advantages in using waste concrete blocks as aggregates. For example, after the building is di...

Problems solved by technology

On a general construction site, only the car washing site has a certain volume of slurry pool. The above equipment is cleaned anywhere. The concrete mixing station uses a lot of water to wash the mixer and the transport vehicle every day. The slurry water of these washing equipment contains cement slurry and aggregate. The impurities and admixtures brought in by aggregates, such as sand and gravel in cement slurry, can be recycled, but now the sand and gravel slurry are not separated from water and discarded at will, resulting in waste of materials. It is beneficial to the treatment of waste water. The water for cleaning cement slurry or concrete has strong alkalinity, and the pH value is relatively high, which can reach about 12. Random discharge will pollute the environment.

[0005] Waste concrete makes high-quality concrete aggregate, which has good reusability. Waste concrete will be cleaned up when it is being demolished. Because the size of waste concrete is different during demolition, it is not convenient for carts to be transported. Therefore, it needs to be crushed before proceeding. transportation, but when crushing waste concrete, since the waste concrete is covered with steel bars, it is easy to get stuck between the two crushing blade holders when the concrete is crushed by the crushing blade holder, causing the two crushing blade holders to get stuck, which affects the For the subsequent treatment of waste concrete, a crushed concrete recovery device is introduced for this purpose
