Building solid waste crushing and sorting equipment based on light substance treatment

Abstract

The invention discloses building solid waste crushing and sorting equipment based on light substance treatment, which comprises a feeding machine, a jaw crusher, a material conveying box and a winnowing box, and is characterized in that a powder material separating box which is matched with a material conveying belt and is provided with a plurality of ultrasonic vibration pieces is additionally arranged in the material conveying box, and a magnetic separation mechanism is arranged at the upper part of the material conveying belt; the broken aggregate conveyed on the conveying belt is vibrated and dispersed, the accumulation state is continuously changed, the magnetic separation effect of the magnetic separation pieces on iron materials is improved, fine disintegrating slag is screened out through the screen holes in the process, the situation that in the subsequent winnowing process, the winnowing effect of light materials is affected due to excessive fine disintegrating slag in the aggregate is avoided, and in the second-stage sorting process, the secondary sorting efficiency is improved. And the ultrasonic blanking plates expanding towards the two sides are additionally arranged, so that the diffusion vibration surface of the crushed aggregate subjected to secondary crushing is expanded, light objects in the building aggregate can be blown out of the winnowing opening as much as possible under the action of wind power, and the multi-stage sorting effect is improved.
