A concrete pulverizer

Abstract

The invention discloses a concrete pulverizer, and relates to the field of building waste treating equipment. The concrete pulverizer comprises a pulverizing device and a conveying device for conveying building waste to the pulverizing device, the pulverizing device comprises a vertically-arranged shell, a feeding hopper arranged at the top of the shell, a pulverizing cavity arranged below the feeding hopper and communicating with the feeding hopper and a pulverizing unit located in the smashing cavity, the pulverizing unit comprises a pulverizing roller vertically arranged in the pulverizingcavity and a pulverizing motor used for driving the pulverizing roller to rotate, a material leaking hole is formed in the side wall of the pulverizing cavity, a fine material cavity is formed betweenthe side wall of the pulverizing cavity and the side wall of the shell, a coarse material cavity is formed between the side wall of the pulverizing cavity and the side face of the pulverizing roller,and a fine material discharging device and a coarse material discharging device communicating with the fine material cavity and the coarse material correspondingly are arranged below the shell. By means of the concrete pulverizer, pulverizing of the building waste can be achieved, classification of pulverized products can be achieved, and the pulverized products can be applied to different places.

Description

technical field [0001] The invention relates to the field of construction waste treatment equipment, in particular to a concrete pulverizer. Background technique [0002] With the progress of society, various buildings are constantly being built, but at the same time many old houses are being demolished, during which a lot of construction waste will be produced. 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, and pipe networks by construction units or individuals. The main components of construction waste are bricks, sand and gravel, and lower house soil. At present, the amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. With the reconstruction of old cities, the demolition of villages in the city, and the reconstruction of roads, there will be more and more construction wa...

Problems solved by technology

With the reconstruction of old cities, the demolition of villages in the city, and the reconstruction of roads, there will be more and more construction waste. However, most of the construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is piled in the open air or landfilled. A large amount of construction expenses such as land acquisition fees, garbage removal and transportation fees, etc.
