A device for treating construction waste in civil engineering

Abstract

The invention discloses a civil engineering construction waste treatment device, which belongs to the technical field of construction waste treatment. The bottom of the feed hopper of the waste treatment device is provided with a cold treatment chamber, the cold treatment chamber is provided with a slant plate assembly for extending the transportation journey of construction waste, and the cold treatment chamber is also equipped with a refrigerant spraying mechanism, and the refrigerant spraying mechanism passes the conveying pipe and the refrigerant The storage mechanism is connected, and a control valve is provided on the delivery pipeline; the refrigerant spraying mechanism is located above the swash plate assembly and can move back and forth along the length of the swash plate assembly. The material is transported to the screw pusher mechanism of the secondary crushing mechanism, the bottom of the cold treatment chamber is also equipped with crushing teeth, and the discharge port of the secondary crushing mechanism is also equipped with a first material output device. The waste processing device of the present invention realizes an embrittled and easily crushed state at a low temperature through cooling, improves crushing efficiency, reduces energy consumption, and prolongs service life of equipment.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a civil engineering construction waste treatment device. Background technique [0002] With the rapid development of our country's economy and the acceleration of urbanization, more and more construction wastes are produced in the process of urban construction. These construction waste materials not only occupy a large amount of land, but also cause serious pollution to the urban environment and cause serious damage to people's living environment. Serious threats, but construction waste is not completely garbage, it can be crushed, screened, processed and converted into new resources that can be reused to realize the recycling of construction waste; [0003] Since construction waste is generally a massive solid material with a certain hardness, such as concrete blocks, bricks, etc., the higher hardness brings certain difficulties to waste crushing. The crushi...

Problems solved by technology

[0003] Since construction waste is generally a massive solid material with a certain hardness, such as concrete blocks, bricks, etc., the higher hardness brings certain difficulties to waste crushing. The crushing mechanism of the construction waste treatment device in the prior art has low crushing efficiency. Crushing consumes a lot of energy, and the crushing mechanism works for a long time due to the high energy consumption of the equipment, which leads to the breakdown of the crushing mechanism, reduces the service life, and increases the cost of waste disposal
