Description

Technical Field

[0001] The utility model relates to the technical field of construction waste recycling and processing devices, in particular to a raw material processing device for producing autoclaved aerated concrete blocks using construction waste. Background Art

[0002] With the acceleration of urbanization, the emission of construction waste (such as discarded concrete blocks, bricks, mortar, etc.) has increased dramatically, bringing tremendous pressure to the environment. Traditional treatment methods such as landfill and incineration not only occupy a large amount of land resources, but may also cause secondary pollution. At present, in order to achieve the effect of environmentally friendly treatment of construction waste, construction waste is usually subjected to secondary processing operations to make corresponding autoclaved aerated concrete blocks. Concrete blocks can be used as a new round of building materials to achieve the effect of environmentally friendly production and pollution reduction.

[0003] When using construction waste to produce autoclaved aerated concrete blocks, the raw materials need to be processed. Common processing operations include crushing, etc. When performing crushing operations, they are usually performed on corresponding crushing equipment. There are many types of crushing equipment on the market, but most crushing equipment lacks components that can remove dust, which will cause dust to fly everywhere, polluting the environment and causing harm to the human body. Although some crushing equipment is equipped with a spray component for dust removal, the water after spraying will soak the raw materials, affecting the performance of the raw materials and further affecting the subsequent block preparation effect. In view of this, we propose a raw material processing device for producing autoclaved aerated concrete blocks using construction waste. Utility Model Content
