Integrated sorting and recycling device for construction wastes

Abstract

The invention discloses an integrated sorting and recycling device for construction wastes, which comprises a box body and supporting legs arranged at four corners of the lower end of the box body, wherein the lower end of each supporting leg is provided with a supporting block for increasing the supporting area, a feeding hopper for feeding is arranged above the box body, a lower port of the feeding hopper is communicated with a feeding port of the box body through a discharging pipe, and the box body is internally provided with a sorting mechanism for sorting the wastes. According to the invention, an improvement is made in view of disadvantages of the existing device, and the iron removal mode is optimized; iron impurities are attracted to the surface of a transmission belt by using thestrong magnetic property of a magnetic ring, the iron impurities are separated from other impurities close to a blanking pipe under the action of gravity along with the rotation of the transmission belt, the magnetic force received by the magnetic impurities is smaller and smaller, and finally the magnetic impurities drop from the transmission belt, so that the separation of the iron impurities is completed, and thus the drawback of poor sorting effect of the existing device is overcome.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment equipment, in particular to an integrated sorting and recycling device for construction waste. Background technique [0002] With the vigorous development of the national economy, the national infrastructure is also constantly being updated and constructed, especially the construction of railways and expressways, as well as the transformation of urban buildings. The development of the city has led to the continuous construction of various housing projects, and the old buildings have been demolished one after another. During the demolition of houses, a large amount of solid waste——construction waste will be generated. At present, the amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Calculated on the basis of 500-600 tons / 10,000 square meters, by 2020, my country will add about 30 billion square meters of new construction...

AI Technical Summary

Problems solved by technology

However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of construction expenses such as land acquisition fees, garbage removal and transportation fees, and at the same time, during the process of clearing, transporting and stacking Problems such as the scattering of dust and flying dust and sand have caused serious environmental pollution.

[0003] The existing construction waste recycling is mainly to crush the waste and then process it, which leads to the destruction of some recyclable materials, the utilization rate is not high, and there will be some iron nails and iron wires in the materials and the like will cause damage to the crushing device. In response to this problem, the existing patent notification number CN207970973U discloses a sorting and recycling device, which uses magnetic force to move the impurities in the waste to one side Attract the metal waste from the mixed waste, but this device will make the metal block move to the side of the conveyor belt, which will bring out some non-metallic impurities, resulting in insufficient sorting
