Pollution-free treatment apparatus for municipal construction engineering wastes

Abstract

The invention discloses a pollution-free treatment apparatus for municipal construction engineering wastes. The apparatus comprises a first supporting frame, a second supporting frame, a masonry crusher, a broken stone conveyer and a waste metal separation conveyer, a sandy soil separation sieve plate is arranged on the first supporting frame, a sandy soil feeding holder is arranged at the lower side of the sandy soil separation sieve plate, a sandy soil recovery tank is arranged at the lower side of the front end of the sandy soil feeding holder, the broken stone conveyer is arranged on the second supporting frame, the waste metal separation conveyer is arranged at the lower side of the broken stone crusher, a waste metal discharging holder and a waste metal recovery tank are arranged atthe rear side of the waste metal separation conveyer, the broken stone conveyer is arranged at the lower side of the waste metal separation conveyer, a broken stone discharging holder and a broken stone recovery tank are arranged at the right side of the broken stone conveyer, and a broken stone baffle plate is arranged at the front side of the left end of the broken stone conveyer. Construction wastes with various different properties are concentrated and recovered, so high cost brought by intensive breaking and sorting of the construction wastes is avoided, resources are saved, and the utilization rate of the construction wastes is improved.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a non-pollution treatment device for municipal construction waste. Background technique [0002] The main components of construction waste are concrete, bricks, sand, gravel, etc. With the progress of urban construction, construction of new projects, old city renovation and demolition, road reconstruction, etc., will inevitably produce a large amount of construction waste. At present, the amount of construction waste has accounted for 30%-40% of the total amount of urban waste. Most of the construction waste is transported by the construction unit to the suburbs or rural dumps designated by the relevant departments without any treatment. The disposal is open-air stacking. Or landfill, which will consume a large amount of land resources, and at the same time, problems such as dust, dust and sand flying in the process of clearing, transporting and stacking have...
