Problems solved by technology

However, with the gradual shortage of land resources, landfill will bring many unfavorable social problems. At the same time, because the stone, cement, and steel materials can be recycled, hard particles can be used as high-quality raw materials for road paving and other projects. After separation Steel materials can be used as high-quality raw materials for steelmaking, so the treatment of construction waste has great social and economic benefits
At present, there are also machinery for construction waste treatment, mainly to crush construction waste, and then carry out manual sorting or magnetic separation after deep crushing, but the mixture obtained after crushing still cannot be effectively used, and it still needs further research according to different uses. for further screening and processing
At present, there are relatively few studies on the construction waste treatment of production line integration, and the production efficiency of this type of research is not very high, and the effect is not very good

Embodiment 1

[0050] Further explanation with the attached drawings: such as Figure 1 to Figure 3 The construction waste crushing and screening device shown includes a primary crushing screening component, a fine crushing screening component and a grinding screening component.

[0051] Such as figure 1 As shown, the primary crushing screening components include the main garbage inlet 11, the inlet vertical pipe 12, the ash retaining sac 13, the outer wall of the primary crushing cavity, the primary crushing cavity inlet (the lower part of the inlet vertical pipe), the primary crushing shaft 14, and the primary The breaking blade 15, the initial breaking motor 16, the initial breaking cavity outlet (the lower right of the initial breaking shaft), the first vibrating screen 17, the first vibration generator 18 and the original soil collection box 19; the outer wall of the initial breaking cavity is as a whole In a horizontal cylindrical structure, the initial breaking cavity inlet is set at the...

Embodiment 2

[0066] A method for crushing and screening construction waste, using the construction waste crushing and screening device of Example 1, specifically including the following steps:

[0067] (1) Drain the construction waste into the outer wall of the primary crushing cavity through the main entrance of the waste, start the primary crushing motor, and use the primary crushing blades to perform primary crushing of the materials entering the primary crushing cavity. The soil during the crushing process passes through the primary crushing cavity. A vibrating screen falls into the original soil collection box, mainly the original soil less than 25mm, because the primary crushing can peel off most of the original soil, and the original soil basically has no negative effect on the environment, so the original soil can be directly After being dumped to wasteland for fertilizer, it can be used as ordinary land. Therefore, after the original soil collection box is full, the soil material is d...

Abstract

The invention belongs to the field of equipment related to building and particularly relates to a building waste crushing and screening device and a specific crushing and screening method. The devicecomprises a primary crushing and screening component, a fine crushing and screening component and a milling and screening component. By specifically arranging all the components and specifically limiting steps of the method, inorganic nonmetal hard particles of different particle sizes can be obtained finally; besides, steel materials can be recycled as comprehensive as possible by carrying out specific magnetic selection at different stages and different particle sizes; furthermore, secondary pollution to the environment can be avoided finally; and thus, building waste can be disposed comprehensively, and manpower cost can be greatly reduced.

Description

Technical field [0001] The invention relates to the field of equipment related to building construction, and also to the field of solid waste recycling and treatment, and in particular to a device and method for crushing and screening construction waste. Background technique [0002] Construction waste mainly contains stone, cement, steel (iron), soil and some plastics, foams and other organic materials, and the above-mentioned various materials are generally consolidated together, which requires a lot of manpower and material resources to deal with. At present, it is mainly divided by manual Landfill treatment after selection. However, with the gradual shortage of land resources, landfilling will bring about many unfavorable social problems. At the same time, since the stone, cement, and steel materials can be recycled, hard particles can be used as high-quality raw materials for road paving and other projects. Steel materials can be used as high-quality raw materials for steel...
