Surface modification strengthening method for waste concrete recycled aggregate

SHI PANPAN / LIU TIANFANG

The invention discloses a surface modification strengthening method for waste concrete recycled aggregate. The method mainly includes the following steps: S1, preparation; S2, feeding; S3, friction cleaning; S4, air jet cleaning; S5, water spray cleaning; and S6, discharging. A surface modification strengthening device for the waste concrete recycled aggregate comprises a box body, limiting grooves are symmetrically formed in the inner wall of the box body, an L-shaped plate is elastically connected in each limiting groove through a spring, the side wall of each L-shaped plate is slidably connected with the inner wall of the box body in a sealing manner, a feeding port is formed in the upper end face of the box body, and the projection of the feeding port is located between the two L-shaped plates. By means of the surface modification strengthening method and device for the waste concrete recycled aggregate, the aggregate can be continuously and quickly kneaded to separate impurities adhering to the surface of the aggregate from the aggregate, and then the aggregate can be jetted with air and sprayed with water respectively to further separate the aggregate from the impurities, sothat the cleanliness of the aggregate is ensured, and the use effect of the aggregate is improved.

本发明公开了一种废弃混凝土再生骨料表面改性强化方法，主要包括以下步骤：S1、准备；S2、投料；S3、摩擦清理；S4、喷气清理；S5、喷水清理；S6、出料；一种废弃混凝土再生骨料表面改性强化设备，包括箱体，所述箱体内壁对称开设有限位槽,每个所述限位槽内均通过弹簧弹性连接有L形板，且每块L形板侧壁均与箱体内壁密封滑动连接，所述箱体上端面开设有进料口，且进料口的投影位于两块L形板之间。本发明可以连续快速的对骨料进行搓揉处理，使得骨料表面粘附的杂质与骨料分离，之后能够分别对骨料进行喷气和喷水，进一步的将骨料与杂质进行分离，从而保证骨料的清洁性，提高骨料的使用效果。
