Crushing and sorting device for building

Abstract

The invention discloses a crushing and sorting device for a building, which comprises a water separation flow channel; a crusher and a first grating are sequentially installed on the water separation flow channel in the water flow direction; an outlet end of the water separation flow channel is communicated with a water storage tank with the open top face; a rotating disc magnetic separation unit is rotatably installed in the water storage tank; a first channel and a second grating are arranged in the water storage tank; the inlet ends of the first channel and the second grating are both lower than the rotating disc magnetic separation unit and communicated with the outlet end of the rotating disc magnetic separation unit; the outlet end of the first channel is communicated with the inlet end of a metal packaging unit; and the outlet end of the second grating is communicated with the inlet end of a building material packaging unit. The crushing and sorting device for the building provided by the invention is provided with two sorting structures, plastic, wood, reinforcing steel bars, concrete and bricks can be sorted in sequence, the labor intensity is reduced, the efficiency is improved, building materials can be moisturized through water sorting, dust floating is reduced, finally, the building materials can be conveniently packaged through the packaging unit, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a crushing and sorting device for construction. Background technique [0002] With the acceleration of urban modernization in our country, the demolition of old buildings is also increasing. The structure of demolished objects has also developed from brick and wood structure to mixed structure, frame structure, plate structure, etc., from house demolition to demolition of buildings or structures such as chimneys, water towers, bridges, and docks. Thereby demolition construction of building has formed a kind of industry trend in recent years. [0003] my country is the largest construction market in the world. The current construction volume exceeds half of the world's total. The amount of waste generated and discharged in urban construction is also growing rapidly. Among them, construction waste accounts for about 30%-40% of the total waste. According to the existing data,...

Problems solved by technology

In addition, random stacking of construction waste is likely to cause safety hazards, seriously pollute water resources, and occupy a large amount of land. Therefore, it is imminent to recycle construction waste

[0004] Common construction wastes are concrete, bricks, steel bars, wood boards and plastic products, etc., all of which can be recycled. However, the existing technology only transports construction wastes after they are crushed. The dust is large, the sorting is slow, and the efficiency is low.
