Embodiment 1

[0084] Embodiment 1. The process layout of the in-line factory type construction waste resource treatment system

[0085] Such as figure 1 As shown, a factory-style construction waste resource treatment system in this embodiment includes a pretreatment unit 1 , a homogenizing air-drying unit 2 and a recycled material processing and production unit 3 arranged in sequence.

[0086] The pretreatment unit 1 includes a construction waste transport vehicle dumping and turnover site 11 , a construction waste pretreatment production line 12 and a muck storage bin 13 arranged in sequence.

[0087] Such as figure 2 As shown, the construction waste pretreatment production line 12 is a construction waste joint extrusion harmless treatment system, and the construction waste joint extrusion harmless treatment system includes a primary coarse crushing equipment 121, a steel structure conveyor 122, a The first-level debris sorting conveyor 123 and the first-level magnetic separation equipm...

Embodiment 2

[0110] Embodiment 2, process layout of L-shaped factory-style construction waste recycling system

[0111] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the two vertical sides of the homogenization air-drying unit 52 of the present embodiment are respectively provided with a pretreatment unit 51 and a recycled material processing production unit 53, and the pretreatment unit 51 and the homogenization The position of the air-drying unit 52 forms a first L-shaped layout, and the positions of the pretreatment unit 51 and the recycled material processing and production unit 53 form a second L-shaped layout. The two L-shaped layouts are suitable for the implementation of construction waste recycling in square plots. When the factory-style construction waste resource processing system constitutes two L-shaped layouts, the construction waste pretreatment production line 512 and the muck storage bin 513 are adjacent to the first homogeniz...

Embodiment 3

[0112] Embodiment 3, the process flow of the factory-style construction waste resource treatment system

[0113] The process flow of the factory type construction waste recycling system of the present invention, the steps are as follows:

[0114] Such as figure 2 As shown, step 1, feeding: construction waste transport vehicles or loaders, both of which are transport equipment 1220, and the transport equipment pours construction waste into the first hopper 1210, and enters the feeder through the hopper. The feeder 129, the feeder 129 sends the construction waste into the primary extrusion crushing equipment 121;

[0115] Step 2, first-level coarse crushing of construction waste: the first-level extrusion and crushing equipment 121 squeezes, splits, and crushes the construction waste to crush the construction waste to a particle size below 200mm;

[0116] Step 3, first-level separation of impurities: construction waste is discharged from the lower outlet of the first-level ex...

Abstract

The invention discloses a factory type construction waste resourceful treatment system and a technological process of the factory type construction waste resourceful treat system and belongs to the technical field of construction waste treatment. The factory type construction waste resourceful treatment system comprises a pretreatment unit, a homogenized drying unit and a recycled material processing production unit which are arranged in sequence. The layout of the technical scheme includes that no matter how the specification and the size of the components and the moisture content of the construction waste change, the normal production of three recycled materials of the construction waste resourceful treatment can not be influenced; and no matter how the three recycled materials of the construction waste resourceful treatment are adjusted, combined and changed, the normal production of the construction waste pretreatment can not be influenced. The processing and production of the recycled materials refer to breaking and grinding of the construction waste residue after harmless treatment, stripping of mishmash, homogenization and drying, the moisture content of the construction residue can be basically controlled below 6%, and therefore smooth production can be achieved.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of resources, in particular to a factory-style construction waste resource treatment system and a process flow thereof. Background technique [0002] According to the research report of the Political Research Center of the Ministry of Housing and Urban-Rural Development, by 2030, my country will demolish 20 billion square meters of old buildings and generate 20 billion tons of construction waste. Most of the old houses demolished in my country at this stage and in the next 20 years are brick-concrete structures built before the 1990s. Usually brick-concrete structure construction waste, clay sintered bricks account for about 60%, concrete accounts for about 15%, mortar and wall covering about 15%, and other waste ceramics, waste glass, wood blocks, soil and steel bars total about 10%. That is, the brick-concrete structure construction waste clay fired bricks account for the vast...
