Civil engineering construction waste treatment device

Abstract

The invention discloses a civil engineering construction waste treatment device and belongs to the technical field of construction waste treatment. A cold treatment chamber is formed in the bottom ofa feeding hopper of the civil engineering construction waste treatment device; a sloping plate component for lengthening the transportation stroke of construction waste is arranged in the cold treatment chamber; a refrigerant spraying mechanism is further arranged in the cold treatment chamber and communicates with a refrigerant storing mechanism through a conveying pipeline; a control valve is arranged on the conveying pipeline; the refrigerant spraying mechanism is positioned above the sloping plate component and can do reciprocating motion in the length direction of the sloping plate component; a spiral pushing mechanism capable of conveying the material falling off the sloping plate component to a secondary crushing mechanism is arranged at the bottom of the sloping plate component; crushing teeth are further arranged at the bottom of the cold treatment chamber; and a first material output device is further arranged below a discharging hole of the secondary crushing mechanism. Thecivil engineering construction waste treatment device realizes the brittle easy-to-crush state at the low temperature through cooling, so that the crushing efficiency is improved, energy consumption is reduced and the service life of the civil engineering construction waste treatment device is prolonged.

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...

AI Technical Summary

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
