Construction waste sorting equipment

Abstract

The invention provides construction waste sorting equipment which comprises a rack, a first belt conveyor, a material distributing box and a settling box are arranged on the rack, a first scattering roller and a second scattering roller are rotationally connected into the material distributing box, a first blanking channel is formed between the discharging end of the first belt conveyor and the first scattering roller, and a second blanking channel is formed between the discharging end of the second belt conveyor and the second scattering roller. A second blanking channel is formed between the first scattering roller and the second scattering roller, and a first air supply pipe and a second air supply pipe are arranged in the material distribution box. According to the construction waste sorting device, construction waste can be effectively separated into heavy materials, medium-heavy materials and light materials according to needs, agglomerated materials are effectively prevented from directly flowing out of the first discharging channel, crushing or scattering treatment does not need to be conducted in advance, the sorting efficiency is relatively high, and meanwhile the impurity rate is relatively low.

Description

technical field [0001] The invention relates to a garbage disposal device, in particular to a construction garbage sorting device. Background technique [0002] Construction waste refers to the waste generated during the construction, repair and demolition of buildings, including sand and gravel, bricks, concrete blocks, waste wood, glass, asbestos, paper scraps, waste plastics, films and metals mixed with each other. Sorting construction waste for reuse can not only reduce pollution, but also turn waste into treasure and save costs. [0003] At present, the construction waste sorting equipment on the market can usually only screen out two kinds of materials: heavy and light. However, construction waste usually contains many medium and heavy materials between heavy and light. Such as wood blocks, hard plastics, etc., these medium and heavy objects are easily mixed into heavy or light materials, resulting in a relatively high impurity content of the sorted materials.

AI Technical Summary

Problems solved by technology

This kind of construction waste screening equipment can separate construction waste into heavy, medium-heavy and light materials according to needs. The material in the lump cannot be fully dispersed, so it needs to be crushed or dispersed before being sent to the equipment, which increases the process and affects the separation efficiency. After the outer surface of the layer separation cylinder absorbs a layer of substances, it is difficult to continue to adsorb other materials, so that some medium-heavy materials may be discharged from the heavy material outlet under the action of gravity, and if the speed of the double-layer air separation cylinder is increased to absorb more materials, Then there may be part of the adsorbed material that is thrown to the light material conveyor or the medium material outlet under the action of centrifugal force, so the impurity content of the sorted material is still relatively high
