Technological method and system for treating construction waste

Abstract

The invention provides a technological method and system for treating construction waste. The technological method comprises the steps that demolition waste is crushed into mixed materials; concrete block materials are treated by a first screening device, and first oversize materials, with the particle size larger than the screening limit of a first screening device, in the concrete block materials enter a first winnowing device for subsequent treatment; decoration waste is conveyed to a second screening device, waste, with the particle size larger than the second screening limit of the secondscreening device, in the decoration waste is obstacles, and second undersize materials with the particle size smaller than the second screening limit enter a third screening device; third oversize materials, with the particle size larger than the third screening limit of the third screening device, in the second undersize materials enter a second winnowing device, and third undersize materials with the particle size smaller than the third screening limit enters a fourth screening device; and oversize materials, with the particle size larger than the fourth screening limit, in the third undersize materials enter the first winnowing device, and undersize materials with the particle size larger than the fourth screening limit are discharged to an intermediate storage bin. The treatment efficiency of the construction waste can be improved.

Description

technical field [0001] The invention relates to the technical field of waste disposal, in particular to a process method and system for processing construction waste. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] Construction waste generally includes house demolition waste and decoration waste. Due to the particularity of the country, house demolition waste is generally dominated by blocks containing miscellaneous walls, that is, most of the house demolition waste is hanging block concrete containing steel bars. The decoration waste is generally the remaining garbage after individual decoration. Compared with the house demolition waste, the aggregate content in the decoration waste is less, while other usable substances (such as non-ferrous metals, plastics, wood blocks, etc.) more. Due to the large volume of some decoration waste, some individua...

AI Technical Summary

Problems solved by technology

If the above-mentioned general treatment method is adopted, the equipment will wear more seriously, but the treatment efficiency is often low

Moreover, most of the existing wool materials after construction waste treatment cannot be reused, and the problem of construction waste treatment has not been fundamentally solved.
