Abstract

The invention discloses a screening device for preparing recycled aggregate concrete from construction waste, and belongs to the technical field of concrete. A screening device for preparing recycled aggregate concrete from construction waste, including a frame and a stacking box, the frame is set opposite to the stacking box, and the frame is connected with a feeding box, a vibrating screen, and a first collection box in sequence along the vertical direction and the second collection box, the outer edge of the vibrating screen is provided with a coaming plate, the bottom outlet of the feeding box is installed with the first feeding tube placed above the vibrating screen, and the first feeding tube is installed with The material is advanced, and the first feeding cylinder is set in parallel with the vibrating screen, and the top of the vibrating screen is fixed with a V-shaped intercepting plate, and the first conveying material between the outlet of the feeding box and the V-shaped intercepting plate The bottom of the cylinder is provided with a feeding hole, the junction of the V-shaped intercepting plate and the hoarding is provided with a slot, and a feeding channel is connected between the slot and the second collection box; the invention realizes the screening and recycling function of construction waste.

Description

technical field [0001] The invention relates to the technical field of concrete treatment, in particular to a screening device for preparing recycled aggregate concrete from construction waste. Background technique [0002] Recycled concrete aggregate is processed from construction waste. Regenerated concrete aggregate can effectively reduce land occupation and environmental pollution caused by construction waste. When processing construction waste for construction aggregate, it is necessary to remove the steel bars and iron wires in the concrete, and then crush the construction waste through a pulverizer, and then screen the construction aggregate to make the construction aggregate a specific size , the existing building aggregates are generally screened in a sieving manner, and the problems existing in the screening of existing building aggregates are as follows: [0003] The clogging of the sieve plate results in low aggregate screening efficiency, which results in poor ...
