Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment, in particular to a steel bar concrete separation mechanism in construction waste. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, residual mud and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals. Some of the construction waste contains a large amount of metal products, such as concrete waste mixed with steel bars. When the steel bars need to be separated, a separation mechanism is needed;

[0003] The traditional separation method is that workers beat the concrete into blocks, exposing the steel bars inside, and then take away the steel bars. However, in this way, only larger steel bars can be picked up. Then, the small steel bars hidden inside the broken concrete blocks cannot be found and taken out. Then, when the waste concrete blocks are used or processed again, the hardness of the small steel bars hidden in them can easily cause damage to the processing machines. At the same time, when used for paving the ground, the small steel bars can easily cause punctures to the soles of the workers' feet. For this reason, we propose a steel bar concrete separation mechanism in construction waste to solve the above problems. Utility Model Content
