An integrated sorting and recycling device for construction waste

Abstract

The invention discloses an integrated sorting and recycling device for construction waste, which comprises a box body and legs arranged at the four corners of the lower end of the box body, and the lower end of the legs is provided with a support block for increasing the supporting area. A hopper for feeding is provided above the box, and the lower port of the hopper communicates with the feed port of the box through a feeding pipe, and a sorting mechanism for sorting waste is provided inside the box , the present invention improves the disadvantages of existing devices, and optimizes the iron removal method: the ferrous impurities are adsorbed on the surface of the conveyor belt by using the strong magnetic properties of the magnetic ring, and as the conveyor belt rotates, under the action of gravity, the iron impurities Impurities are separated from other impurities near the discharge pipe. As the conveyor belt continues to rotate, the magnetic force received by the iron impurities becomes smaller and smaller, and finally falls off from the conveyor belt, thereby completing the separation of iron impurities, thus solving the problem. There are disadvantages of poor sorting effect in the device.

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
