Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment, specifically to a civil engineering construction waste treatment device. Background Technology

[0002] Construction waste management refers to the scientific and rational disposal of waste generated during construction activities such as new construction, renovation, expansion, and repair, including demolition and decoration of buildings. This includes waste materials such as concrete blocks, brick fragments, waste wood, waste metal, waste plastics, and waste glass. These operations encompass multiple aspects, including collection and transportation—gathering scattered waste materials and transporting them to designated treatment sites; sorting—separating different types of waste manually or mechanically for targeted processing; pre-treatment such as crushing and screening—crushing larger waste materials into smaller particles and screening them for recycling; reprocessing—using waste concrete to produce recycled aggregates for new building materials, and remelting waste metal to create new metal products; and safe landfilling and incineration for unusable waste, aiming to reduce negative environmental impacts and achieve the goals of reducing, neutralizing, and recycling construction waste.

[0003] However, existing civil engineering construction waste treatment facilities still have the following areas for improvement:

[0004] 1. Some existing civil engineering construction waste treatment devices do not have good dust removal devices. When crushing construction waste, a large amount of dust and fine particulate matter are generated around the device and spread to the surrounding area, which may affect the health of the workers.
