Abstract

The invention discloses a screening device for preparing recycled aggregate concrete from construction waste, and belongs to the technical field of concrete. The screening device for preparing the recycled aggregate concrete from the construction waste comprises a rack and a material stacking box, wherein the rack and the material stacking box are oppositely arranged; the rack is sequentially connected with a feeding box, a vibrating screen, a first collecting box and a second collecting box in the vertical direction; a surrounding plate is arranged on the outer edge of the vibrating screen ina surrounding mode; a first material conveying barrel arranged above the vibrating screen is arranged at a discharging port in the bottom of the feeding box; a material progressive assembly is arranged in the first material conveying barrel, and the first material conveying barrel is parallel to the vibrating screen; the top of the vibrating screen is fixedly connected with a V-shaped intercepting plate; a material conveying hole is formed in the bottom of the first material conveying barrel between the discharging port of the feeding box and the V-shaped intercepting plate; an open groove isformed in the joint of the V-shaped intercepting plate and the surrounding plate; and a material conveying channel is connected between the open groove and the second collecting box. According to thescreening device, the screening and recycling functions of the construction waste are realized.

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 ...
