Recycling method of building concrete

Abstract

The invention provides a recycling method of building concrete. The recycling method comprises the following steps that brick concrete to be crushed is guided into a transfer device mounted on a mounting frame body through a feeding assembly mounted on the mounting frame body, and the transfer device runs and drives the brick concrete into an impact device mounted on the mounting frame body; the impact device runs and conducts primary impact crushing treatment and secondary impact crushing treatment on the brick concrete, the impact device runs and conducts continuous impact crushing on the brick concrete, the brick concrete is transferred to the position below a grinding device through the transfer device after being crushed through the impact device, and the brick concrete is ground through the grinding device; and then the transfer device runs and transfers the brick concrete ground by the grinding device into a discharging assembly, and finally the brick concrete is guided out. According to the method, the brick concrete can be automatically crushed and ground into small particles and then guided out, the recycling rate of the building brick concrete is increased, the economic cost is reduced, the energy consumption is reduced, and broad environment-friendly application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of building brick-concrete crushing, in particular to a recycling method for building concrete. Background technique [0002] With the rapid development of my country's economy, large-scale projects such as urban renovation, bridge renovation, and road expansion emerge in an endless stream, but what follows is an increasing amount of construction waste. The amount of construction waste in my country has accounted for 30% of the total amount of urban waste- 40%. However, the vast majority of 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, which consumes a lot of construction funds such as land acquisition fees, garbage removal and transportation fees, and at the same time, during the removal and stacking process Problems such as dust, dust and sand flying have caused serious environmental pollution.

However, the vast majority of 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, which consumes a lot of construction funds such as land acquisition fees, garbage removal and transportation fees, and at the same time, during the removal and stacking process Problems such as dust, dust and sand flying have caused serious environmental pollution. Construction waste has become a public hazard, not only occupying a large amount of arable land, but also not decomposing; it is known that most of the construction waste is masonry, Useful substances such as concrete, and can be reused after crushing
