Description

Technical Field

[0001] The utility model relates to the technical field of recycled aggregates, in particular to a recycled aggregate washing device. Background Art

[0002] Aggregate is a loose granular material that acts as a skeleton or filler in concrete. Aggregate is the main raw material in concrete and plays a skeleton and supporting role in buildings. Aggregate prepared from waste concrete is called recycled aggregate. Recycled aggregate particles are angular, rough, and contain hardened cement mortar. In addition, the concrete block accumulates a lot of microcracks inside due to damage during the crushing process, resulting in large porosity, high water absorption, small packing density, large void ratio, and high crushing index of the recycled aggregate itself. There are a lot of impurities on the surface of the recycled aggregate, so the recycled aggregate needs to be washed.

[0003] The Chinese patent publication number is CN219985605U, and the authorization announcement date is November 10, 2023. In the field of aggregate washing technology, the use of a disturbance rod to rotate the recycled aggregate in the water body is improved, so that the friction generated when it rotates with the water body can complete the cleaning, and the water flow cannot effectively make the impurities with strong adhesion on the surface of the recycled aggregate fall off; a recycled aggregate washing device, including a cleaning device, the cleaning device includes a cleaning box, a first electric push rod, a friction plate, a second electric push rod and a screen. The utility model is provided with a friction plate installed inside the cleaning box, and the friction plate can move in the horizontal direction and the vertical direction under the action of the first electric push rod and the second electric push rod, and the recycled aggregate is put into the cleaning box through the feed pipe and placed on the screen, so that the friction plate can make the recycled aggregate rub on the screen, and the recycled aggregates can also effectively rub against each other, so as to effectively clean the surface of the recycled aggregate.

[0004] The existing water washing device pours the recycled aggregate into the water washing tank, stirs the recycled aggregate in the water washing tank through a disturbance rod, and makes the recycled aggregate rotate in the water body. The friction generated by the rotation of the recycled aggregate and the water body is used to achieve cleaning. The washed recycled aggregate is accumulated together with impurities at the bottom of the water washing tank, which is inconvenient to separate, increases the difficulty of unloading the recycled aggregate, reduces the recycled aggregate washing efficiency, and cannot meet the use requirements.
