Description

A construction site garbage crushing sorting recovery device

technical field

The invention relates to the technical field of recycling equipment, in particular to a garbage crushing, sorting and recycling device for construction sites.

Background technique

Construction waste refers to the dregs, spoils, waste materials, residual mud and other wastes generated during the construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. by construction, construction units or individual teams.

At present, the amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Calculated based on the standard of 500-600 tons/10,000 square meters, by 2020, my country will add about 30 billion square meters of construction area , the newly generated construction waste will be a shocking figure. However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of construction expenses such as land acquisition fees and garbage removal fees. Problems such as dust, dust and sand flying have caused serious environmental pollution. The Ministry of Construction's "Urban Construction Waste Management Regulations" came into effect on June 1 last year, requiring any unit and individual not to dump, throw or pile up construction waste at will. Residents should collect construction waste and domestic waste generated in the process of decorating houses separately, and stack them in designated places. Construction waste transfer stations should be set up for the convenience of residents. Heavy fines are also imposed on units and individuals that do not dispose of construction waste in accordance with regulations, so as to strengthen the management of urban construction waste and ensure urban appearance and environmental sanitation. At present, the main treatment method of construction waste in my country is to bury it underground. The harm is that, first of all, it takes up a lot of land. Taking Beijing as an example, according to relevant data, before the construction of the Olympic Games, the demolition of the original buildings and the construction of new construction sites, Beijing has to set up 20 to 30 construction waste disposal sites every year, causing considerable pressure on the land. The second is to cause serious environmental pollution. The construction glue, paint and paint in construction waste are not only high molecular polymer materials that are difficult to biodegrade, but also contain harmful heavy metal elements. These wastes are buried in the ground, which will cause groundwater pollution, directly endanger the lives of surrounding residents, and damage the soil structure and cause surface subsidence. The current landfill method is: bury 8 meters of garbage and add 2 meters of soil layer, but it is basically difficult to re-grow vegetation on the soil layer. The surface of the landfill area will have subsidence and subsidence, and it will take a long time to reach a stable state.

Construction waste is often mixed together during construction, and landfilling waste will cause harm to the environment, and construction waste such as foam, reinforced cardboard cement, etc. can be recycled, but there is no effective separation of waste on the market Recycling equipment.
