A waste building material recycling machine

Abstract

The invention relates to the field of construction waste recycling, in particular to a waste building material recycling machine. There is a concrete discharge port on one side, and the shell is provided with a crushing mechanism, a screening mechanism and a dust removal mechanism; during operation, the reinforced concrete blocks to be treated are added through the feeding port, and the reinforced concrete blocks are crushed by the crushing mechanism and fall off. into the screening mechanism, then the concrete fragments are discharged from the concrete outlet, and the rebar fragments are discharged from the steel outlet. At the same time, the dust removal mechanism absorbs the dust in the shell to reduce dust pollution. This method has a simple structure, and achieves the effect of separating steel bars and concrete powder, which is beneficial to subsequent processing and saves manpower; at the same time, the air blown from the air outlet accelerates the fine concrete particles on the conveyor belt from the strip grooves. On the trough, and discharged from the concrete outlet under the action of gravity.

Description

technical field [0001] The invention relates to the field of construction waste recycling, in particular to a waste construction material recycling machine. Background technique [0002] General waste building materials refer to the solid waste generated during the construction, reconstruction, expansion or demolition of the building by the construction party, which is divided into construction waste and demolition waste. make new uses. [0003] When demolishing building walls, a large amount of reinforced concrete block waste will be produced. The finely divided aggregate produced by the crushing of abandoned building concrete can be used to produce concrete, mortar or blocks, wall panels, floor tiles and other products of corresponding strength grades. ; Reinforced steel can be smelted and made into various metal products after recycling; Generally, the steel bar after reinforced concrete block waste is separated manually. This method is time-consuming and labor-intensive...

Problems solved by technology

[0003] When demolishing building walls, a large amount of reinforced concrete block waste will be produced. The fine aggregate produced after the waste building concrete is crushed and produced can be used to produce concrete, mortar or blocks, wall panels, floor tiles and other products of corresponding strength levels. ; Steel bars can be smelted into various metal products after recycling; generally use artificially separated reinforced concrete block waste broken steel bars, this method is time-consuming and labor-intensive, the production efficiency is low, and the health and safety of workers in the production process There are hidden dangers
