Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment, in particular to a civil engineering construction waste treatment device. Background Art

[0002] In the actual construction process, a lot of construction waste will be generated when the building is under construction. At the same time, most of the current construction projects involve demolishing old houses and building new ones, so a lot of construction waste will be generated during the demolition process, such as shaken-off cement blocks and demolished walls. Due to their large size and the fact that they are mainly composed of cement, bricks or other chemical substances, they cannot be treated together with normal domestic waste and need to be treated separately.

[0003] In the current process of engineering waste treatment, most of them are directly crushed and then transported for treatment. However, the current treatment equipment has low efficiency in crushing, which is prone to incomplete crushing, affecting the treatment effect. In addition, there are metal materials in the waste that are not separated, resulting in a waste of resources if they are treated together later.

[0004] For this purpose, a construction waste processing device with metal separation and enhanced crushing is proposed. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In order to overcome the shortcomings of the existing technology, a civil engineering construction waste treatment device is proposed to solve the problems that the current treatment equipment has low efficiency in crushing, is prone to incomplete crushing, affecting the treatment effect, and the presence of metal materials in the waste is not separated, resulting in a waste of resources in subsequent treatment.
