AI Technical Summary

Technical Problem

In the existing regenerated aggregate treatment technology, the pellet shaping and grinding processes are usually carried out simultaneously, resulting in waste of water resources and environmental burden, and are not efficient and quality.

Method used

A system integrating particle shaping and air abrasion functions was designed. By setting up a multi-layer work box, using vibration shaping and air abrasion mechanism on the annular track, large-area circulating vibration particle shaping and air flow abrasion are realized.

Benefits of technology

The system greatly improves the efficiency and quality of shaping and abrasive recycled aggregate particles, saves water resources and energy, reduces environmental burden, and achieves highly integrated space and energy consumption optimization.

Abstract

The present invention discloses a large-area vibration particle shaping and air grinding and washing system and method for recycled aggregate, comprising a first-layer working box, a second-layer working box, and a third-layer working box stacked from top to bottom and having substantially the same structure; the first-layer working box comprises a main box body, which is a cylindrical box body, and an annular channel is provided at the center of the inner part thereof, and a mobile shaping layer, a fixed grinding and washing layer, and a storage and output layer are provided on the outer periphery of the annular channel from top to bottom; a fan-shaped partition plate is provided at the center of the annular channel, and the fan-shaped partition plate divides its internal space into three-quarters fan-shaped space and one-quarter fan-shaped space. The present invention can be used by stacking the first, second, and third-layer working boxes, and the mobile shaping layer inside the box body of the recycled aggregate put into the top layer cooperates with the fixed grinding and washing layer to realize large-area cyclic vibration particle shaping and air flow grinding and washing, so as to realize the high integration of the entire shaping, screening, grinding, washing, and storage, and greatly save the space and energy consumption originally required.
