Embodiment 1

[0050] Such as figure 1 As shown in FIG. 1 , it shows a schematic structural view of the construction mixed waste sorting comprehensive treatment system of the present invention. The system includes an upper bin 1 for construction mixed waste, and the upper bin 1 is connected to a feeding screening machine 3 through an upper belt conveyor 2 . In this embodiment, the feeding screening machine 3 is connected with a belt conveyor 4 for materials below 5mm and a belt conveyor 5 for materials with a thickness of 5-10mm. The main body of the feeding screening machine 3 is connected to the drum screening machine 7 through the chain conveyor 6, and the middle part of the chain conveyor 6 is also connected with a first iron remover (not shown), the first iron remover is a straddle-type magnetic separator and a permanent The magnetic drum magnetic separator cooperates with the composite device for magnetic separation. In this embodiment, the drum screening machine 7 is connected with ...

Embodiment 2

[0052] see figure 2 , shows a schematic diagram of the construction mixed waste sorting comprehensive treatment method and process flow of the present invention. In this embodiment, the process flow includes the following:

[0053] 1) Sieve the mixed construction waste through a feeding screening machine, and screen out fine materials with a particle size below 5mm and a size of 5-10mm, as well as large mixed materials with a particle size above 10mm;

[0054] 2) Convey the sieve and remove the magnetic metal components through the iron remover;

[0055] 3) Dispersing and separating the materials from which magnetic metal components have been removed by a drum screening machine to obtain aggregates with sizes below 10mm, 10-20mm and 20-31.5mm;

[0056] 4) manually sorting the remaining materials in step 3) to remove unavailable materials;

[0057] 5) Then through one-time crushing and screening, aggregates of different specifications below 10mm, 10-20mm and 20-31.5mm are o...

Abstract

The invention relates to a new construction and decoration mixed waste (hereinafter referred to as mixed construction waste) sorting comprehensive treatment system. By adoption of the system, the mixed construction waste with complicated components can be accurately sorted, various sorts of sorted materials can be comprehensively treated, and thus various sorts of recovered materials capable of meeting the national standard and being used for production are obtained. The system comprises a mixed construction waste feeding bin, a feeding screening machine, a first de-ironing separator, a drum screening machine, a first crushing machine, a first vibration screening machine, a second crushing machine and a second vibration screening machine which are sequentially connected. The mixed construction waste sorting comprehensive treatment system is high in degree of automation, the manual intervention degree is low, and various sorts of the mixed construction waste can be efficiently treated.The invention further relates to a mixed construction waste sorting comprehensive treatment method.

Description

technical field [0001] The invention relates to the technical field of waste treatment, in particular to a sorting and comprehensive treatment system and treatment method for mixed construction waste. Background technique [0002] Construction mixed waste refers to the collective name of muck, waste concrete, waste masonry and other waste generated in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries. According to the classification of generation sources, construction mixed waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc. block, waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction mixed waste is increasing. The amount of construction mixed waste in China has accou...
