Construction waste classifying and crushing device

Abstract

The invention provides a construction waste classifying and crushing device. The device comprises a housing, a floating matter collecting chamber, a floating barrel, a filtering net rail, a big blockfiltering chamber, a small block filtering chamber, a big block stirring rotating barrel, an inner net-shaped barrel and spiral blades, wherein a waste inlet is fixedly connected to the top part of the housing; a floating groove housing is fixedly connected to the upper part of the housing to form a floating groove; the floating matter collecting chamber is arranged at the upper part of the filtering net rail, and the big block filtering chamber is arranged at the lower part of the filtering net rail; the small block collecting chamber is arranged at the lower parts of meshes, and the left part of the small block collecting chamber is fixedly connected to a silt immersing pipeline; a water draining pipe is fixedly connected to the left end of the silt immersing pipeline; and the big blockstirring rotating barrel is rotatably connected to the right side of a fixing bearing. According to the device, the inner part of the device is designed by layers; after construction wastes are poured, water is poured to float and classify bits of wood or other impurities of which the density is less than that of water, and then fine sandstones and big bricks or metals are separated through the meshes; and the big bricks are crushed through the crushing barrel, and then the metal is filtered through the inner net-shaped barrel, and thus classifying and crushing are achieved.

Description

Technical field [0001] The invention relates to a garbage disposal device, in particular to a construction garbage classification and crushing device. Background technique [0002] Construction waste refers to the muck, waste concrete, waste masonry and other wastes produced by people in the production activities of the construction industry such as demolition, construction, decoration and repair. According to the source of generation, construction waste can be divided into engineering waste, decoration waste, demolition waste, engineering mud, etc.; according to the composition of the classification, construction waste can be divided into slag, concrete blocks, crushed stones, bricks and tiles, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. [0003] The amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. According to the standard of 500-600 tons / 10,000 square meters, by 2020, my countr...
