Waste building material recycling machine

Abstract

The invention relates to the field of building waste recycling, in particular to a waste building material recycling machine. The machine comprises a shell, a feeding port is formed at the top of the shell, a reinforcing steel bar discharging port is formed at the bottom of the shell, a concrete discharging port is formed at one side of the shell, and a crushing mechanism, a screening mechanism and a dust removal mechanism are arranged in the shell; and in the working process, reinforced concrete blocks to be treated are added through the feeding port, the reinforced concrete blocks fall into the screening mechanism after being crushed by the crushing mechanism, then concrete fragments are discharged from the concrete discharging port, the reinforcing steel bar fragments are discharged from the reinforcing steel bar discharging port, meanwhile, the dust removal mechanism sucks and removes dust in the shell, and dust pollution is reduced. According to the machine, the structure is simple, the effect of separating the reinforcing steel bars from the concrete powder is achieved, follow-up machining treatment is facilitated, and manpower is saved; and meanwhile, the air blown out of an air outlet accelerates fine concrete particles on a conveying belt to fall into a material guiding groove from a strip-shaped groove, and the fine concrete particles are discharged from the concrete discharging port under the action of gravity.

Description

technical field [0001] The invention relates to the field of construction waste recycling, in particular to a recycling machine for waste building materials. Background technique [0002] General waste building materials refer to the solid waste generated during the construction, reconstruction, expansion or demolition of buildings by the construction party. They are divided into construction construction waste and demolition construction waste. for new uses. [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 labo...

[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
