Problems solved by technology

The combination of traditional jaw crusher and impact crushing stone crushing line is suitable for crushing stone or plain concrete, but the treatment of brick-concrete construction waste often cannot meet the needs
The problems of using the combination of jaw crusher and impact crusher to deal with brick-concrete construction waste are: first, the jaw crusher is a "crocodile mouth" type of one piece and one piece intermittent extrusion crushing, and the fine steel bars and concrete cannot be completely separated, and the prestressed floor concrete after crushing Intermittently wrapped steel bars, magnetic separation equipment is difficult to absorb and magnetically select small steel bars wrapped in concrete, and the thin steel bars wrapped in concrete that are manually sorted need to be manually hammered to peel off the concrete, which is very troublesome and inefficient
Second, the impact crusher is an impact crusher with high-speed rotor impact and inner liner impact, so it is taboo to contain small and long steel bars in the material, because the small and long steel bars will wrap around the rotor or the thick steel bars will jam the rotor. At the same time, the high-speed rotating rotor Repeated impacts break concrete and bricks, and also break wood and fabrics into debris, making it difficult to sort and separate light combustibles
[0011] According to the patent technology search, there is no patent literature related to the harmless treatment of construction waste joint extrusion

Embodiment 1

[0066] Embodiment 1. Construction waste joint extrusion harmless treatment system is used to process house construction waste

[0067] Such as figure 1 As shown, a construction waste joint extrusion harmless treatment system of the present invention includes a first-level extrusion crushing equipment 1, a steel structure conveyor 2, a first-level debris sorting conveyor 3 and a first-level magnetic separation equipment 4 , the output end of the primary extrusion crushing equipment 1 corresponds to the input end of the steel structure conveyor 2, the output end of the steel structure conveyor 2 corresponds to the input end of the primary debris sorting conveyor 3, and the primary magnetic separation equipment 4 Set on the upper part of the first-level sundry sorting conveyor 3, it also includes the second-level extrusion crushing equipment 5, the roller separation conveyor 6, the second-level sundries sorting conveyor 7 and the second-level magnetic separation equipment 8, and ...

Embodiment 2

[0087] Embodiment 2, construction waste joint extrusion harmless treatment method

[0088] Such as figure 1 with figure 2 As shown, a kind of construction waste joint extrusion harmless treatment method of the present invention, the steps are as follows:

[0089] The first step, feeding: construction waste transport vehicles or loaders, both of which are transportation equipment 20, and the transportation equipment 20 pours construction waste into the first hopper 10, and enters the feeding material through the hopper Machine 9, feeder 9 sends the construction waste into the primary extrusion crushing equipment 1;

[0090] The second step, first-level coarse crushing of construction waste: first-level extrusion and crushing equipment 1 squeezes, splits, and crushes construction waste, crushing construction waste to less than 200mm;

[0091] The third step, first-level separation of impurities: construction waste is discharged from the lower outlet of the first-level extrus...

Embodiment 3

[0097] Construction waste joint extrusion harmless treatment system is used to deal with decoration construction waste

[0098] Such as figure 1 As shown, the difference between this embodiment and Embodiment 1 is that the secondary extrusion crushing equipment 5 is a rough-faced roller crusher.

[0099] When the roller separation conveyor 6 handles decoration and construction waste, the gap between the rollers is adjusted to 10-15 mm, which is used to separate construction slag from light combustibles.

[0100] When the system handles decoration and construction waste, a feeding device is provided between the primary debris sorting conveyor 3 and the secondary extrusion crushing equipment 5, and the feeding device is a rod-type feeding device, and the rod The bar gap is 50 mm.

[0101] In the harmless treatment method of combined extrusion of decoration and construction waste, the decoration and construction waste is crushed by primary extrusion and crushing equipment 1, an...

Abstract

A construction waste co-extrusion harmless treatment system and a method thereof in the technical field of construction waste treatment. The system comprises a primary extrusion crushing appliance (1). An output end of the primary extrusion crushing appliance (1) corresponds to an input end of a steel structure conveyor (2), an output end of the steel structure conveyor (2) corresponds to an input end of a primary impurity sorting conveyor (3), a primary magnetic separator (4) is arranged at the upper part of the primary impurity sorting conveyor (3), an input end and an output end of a secondary extrusion crushing appliance (5) respectively correspond to an output end of the primary impurity sorting conveyor (3) and an input end of a roller separating conveyor (6), an output end of the roller separating conveyor (6) corresponds to an input end of a secondary impurity sorting conveyor (7), and a secondary magnetic separator (8) is arranged at the upper part of the secondary impurity sorting conveyor (7). Extrusion crushing and tooth roller crushing two-stage co-extrusion crushing can be performed, so that construction waste concrete brittle materials can be crushed to separate fine reinforcement from concrete, but also excessive crushing of light and combustible soft materials can be avoided.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of resources, in particular to a construction waste combined extrusion harmless treatment system and method thereof. Background technique [0002] The harmless treatment of construction waste in my country is not simply crushing stones. The harmless treatment of building and construction waste in my country involves three major problems of peeling off metal, combustibles, and soil, and the harmless treatment of decoration and construction waste is even more complicated. Practice has shown that in my country's construction waste resource treatment, we must first solve the harmless treatment. For the harmless treatment of construction waste in my country, it is necessary to develop suitable harmless treatment equipment and processes according to the composition characteristics of construction waste in my country and the needs of resource treatment of construction waste residues. ...
