Problems solved by technology
[0005] However, the relative deficiency is that the techniques adopted in these patents all use the method of gravity screening to separate the brick-concrete from the construction waste, and the degree of separation of the brick-concrete is limited. The method of multiple crushing and multiple separations has high production costs, low production efficiency, and low economic benefits

Embodiment Construction
[0027] Attached below figure 1 The technical scheme and specific implementation steps of the invention are described in detail with the embodiments. The described construction waste brick-concrete separation and comprehensive disposal process includes the following steps.
[0028] (1) Pour the construction waste L into the storage yard, and first pass through the impact crusher 1 to crush the raw materials of the large construction waste L to a diameter less than 600mm;
[0029] (2) Send the crushed mixed construction waste L into the feeder 2, and the feeder 2 transports the construction waste L to the first screening machine 3, and the first screening machine 3 initially divides the mixed construction waste L into diameters of 0- 1cm of slag C, mixed garbage B of 1-15cm in diameter, pure concrete block A of 15-60cm in diameter, and the slag C is transported to the first raw material warehouse 17 to be used as raw material for machine-made bricks. The sorted garbage L is divide...

A construction waste brick-concrete separation comprehensive treatment process, comprising the following steps: S1 preliminary separation step, used to crush construction waste and perform preliminary separation of muck, mixed waste and pure concrete blocks; S2 mixed waste treatment step, used to treat The mixed waste is further separated to obtain the final product; S3 pure concrete block processing step is used to further separate the pure concrete block to obtain the final product. The present invention aims to provide a continuous production, high production efficiency, low production cost, and simple operation of construction waste brick-concrete separation and comprehensive treatment process, which can completely separate masonry and concrete in construction waste, which is beneficial to masonry and concrete. The high value-added utilization of pure crushed and screened materials improves economic benefits and realizes the resource recycling of construction waste.
Description
technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste brick-concrete separation and comprehensive treatment process. Background technique [0002] Construction waste refers to the solid waste generated during the construction, expansion, decoration or demolition of buildings, such as: bricks, sandstone, concrete, muck, silt and other wastes. According to different sources of construction waste, it can be divided into construction construction waste, demolition construction waste and decoration construction waste. With the continuous development of my country's construction industry, especially the rapid development of the real estate industry, the annual output of construction waste in my country accounts for 30%-40% of the total urban waste. [0003] At present, the disposal methods of construction waste in my country are mainly open-air stacking or simple landfill, which is relatively bac...
