Description

A sorting and recycling device for construction waste

technical field

The invention belongs to the technical field of waste treatment, and in particular relates to a construction waste sorting recovery treatment device.

Background technique

With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. China is in a period of rapid economic development, and hundreds of millions of tons of construction waste are inevitably produced every year. However, due to Construction waste classification requires additional costs. In order to save costs, the construction unit usually transports construction waste to the suburbs or villages without any treatment, and stacks it in the open air or landfills, which not only takes up a lot of land, but also takes up a lot of time in the process of clearing and stacking. Scattering, dust, flying dust and other problems have caused serious environmental pollution. In addition, the site selection of most urban construction waste dumps is largely random, leaving many potential safety hazards. The vicinity of construction sites often becomes Due to the convenience of construction and the lack of proper protective measures in the temporary storage places of construction waste, under the influence of external factors, construction waste piles collapse, block roads and even rush to other buildings. In the suburbs, Ponds, ponds and ditches are mostly the first choice for dumping construction waste, which not only reduces the ability to regulate and store water bodies, but also reduces surface drainage and flood discharge capabilities.

In order to make reasonable use of construction waste and save construction costs, one of the existing methods is to transport construction waste to relevant waste treatment enterprises for unified treatment, crush the larger construction waste into powder, and produce recycled bricks, blocks, and wall panels , floor tiles and other building materials, or crushed and ground into powder materials to be used as substitutes for fly ash, slag powder, stone powder and other materials and concrete admixtures. This method has a high rate of construction waste classification and recycling, but it is generated during transportation. The dust and sand will cause serious air pollution, and not only the transportation cost is high, but also the cost of waste treatment related equipment is high. It is only suitable for enterprises specializing in renewable construction processing, and the scope of popularization is limited. The construction waste is broken into smaller volumes of construction waste, and the steel bars in the construction waste are separated from the concrete. After the steel bars are selected, the construction waste is crushed again with a crusher, and then the crushed construction waste replaces fly ash and slag. Powder, stone powder and other materials are mixed with concrete. This method can maximize the recycling of steel and maximize the use of construction waste. It is generally carried out directly on the construction site without transporting construction waste, but manual crushing of large-volume construction waste Time-consuming and labor-intensive, low efficiency, the crushing mechanism set up for more reasonable use of construction waste has limited crushing functions, it is difficult to crush large-volume construction waste, low efficiency, and lacks the classification function related to large-scale equipment specialized in renewable construction processing enterprises.
