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
[0030] Attached below figure 1 The technical scheme of the invention and the specific implementation steps are described in detail with the embodiment. The described comprehensive disposal process for the separation of brick and concrete from a kind of construction waste includes the following steps: S1 preliminary separation, S2 mixed waste treatment and S3 pure concrete block treatment .
[0031] Described S1 primary separation step specifically comprises the following steps:
[0032] S1-1, Pour the construction waste L into the yard, and first pass through the impact crusher 1 to crush the raw materials of the large construction waste L to a diameter of less than 600 mm;
[0033] S1-2, send the crushed construction waste L into the feeder 2, and the feeder 2 conveys it to the first screening machine 3; the first screening machine 3 initially divides the crushed construction waste L into diameters 0- 1 cm muck C, mixed waste B with a diameter of 1-15 cm, and pure concrete ...

The invention relates to a brick concrete separation comprehensive disposal process for construction waste. The process comprises the following steps that S1, a preliminary separation step for crushing the construction waste and carrying out preliminary separation on muck, mixed waste and pure concrete blocks is carried out; S2, a mixed waste disposal step for further separating the mixed waste and obtaining a final product is carried out; and S3, a pure concrete block disposal step for further separating the pure concrete blocks and obtaining the final product is carried out. The invention aims to provide the brick concrete separation comprehensive disposal process for the construction waste, the process has the advantages of continuous production, high production efficiency, low production cost and simple operation, bricks and concrete can be fully separated in the construction waste, high added value utilization of pure crushing and screening materials of the bricks and the concreteis facilitated, the economic benefits are improved, and resource recycling of the construction waste is realized.
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...
