建筑物废弃混凝土高品质再生骨料回收设备Building Waste Concrete High Quality Recycled Aggregate Recovery Equipment

技术领域technical field

本实用新型属于涉及建筑材料领域,特别涉及建筑物废弃混凝土循环利用领域,具体是一种建筑物废弃混凝土高品质再生骨料回收设备。The utility model belongs to the field of building materials, in particular to the field of recycled building waste concrete, in particular to high-quality regenerated aggregate recovery equipment for building waste concrete.

背景技术Background technique

近年来我国建筑业迅速崛起,作为普遍使用的建材混凝土大量生产的同时,旧有建筑物的拆除也产生了大量的废弃混凝土。一方面,新混凝土的生产大量消耗砂石等自然资源;另一方面,废弃混凝土的堆积造成了环境污染,影响社会秩序。废弃混凝土的高效回收利用既可以解决废弃混凝土引发的环境污染,又可以作为新混凝土的原料投入生产,减少天然砂石资源的开采,对发展循环经济意义重大。目前国内普遍采用机械挤压、研磨的方法对废弃混凝土进行破碎,生产的再生骨料由于自身损伤以及附着的水泥砂浆较多,与天然骨料的性能差距较大,应用范围受到很大限制。因此实现废弃混凝土中骨料与砂浆的有效分离且不对骨料造成损伤成为废弃混凝土高效回收利用的关键技术问题。In recent years, my country's construction industry has risen rapidly. As a widely used building material, concrete has been mass-produced, and at the same time, the demolition of old buildings has also produced a large amount of waste concrete. On the one hand, the production of new concrete consumes a large amount of natural resources such as sand and gravel; on the other hand, the accumulation of waste concrete causes environmental pollution and affects social order. The efficient recycling of waste concrete can not only solve the environmental pollution caused by waste concrete, but also can be put into production as a raw material for new concrete, reducing the exploitation of natural sand and gravel resources, which is of great significance to the development of circular economy. At present, the methods of mechanical extrusion and grinding are generally used in China to crush waste concrete. Due to the damage of itself and the attached cement mortar, the recycled aggregate has a large performance gap with natural aggregate, and its application range is greatly limited. Therefore, realizing the effective separation of aggregate and mortar in waste concrete without causing damage to aggregate has become a key technical issue for efficient recycling of waste concrete.
