[0002] In the resource recycling process of construction waste, the heavy materials in the waste need to be classified and screened by screening equipment, and the light materials need to be sorted, such as the wood-stone sorting device for air separation of construction waste disclosed in Chinese patent CN215235933U, which includes a rack, a material distribution mechanism and a wood-stone sorting mechanism installed on the rack. The wood-stone sorting mechanism includes a conveying mechanism and a negative pressure suction mechanism. The material distribution mechanism includes an inlet channel, a material distribution channel, and a fan. The conveying mechanism includes a conveying belt with several air holes evenly distributed on it. The negative pressure suction mechanism includes a suction port and a pipeline, and the suction port is sealed under the conveying belt. The existing technology separates the light material from the wood-stone mixture by setting a common fan for the material distribution mechanism and the wood-stone sorting mechanism, using the principle of negative pressure formed by the fan suction port and the blowing port, and separating the wood block by the fan blowing port. The light material is separated by the fan suction port. The separation of light material and wood-stone mixture is achieved by using the material distribution mechanism, and the separation of wood and stone is achieved by using the wood-stone sorting mechanism, which uses the principle that the adsorption force is greater than the inertial force.
