Problems solved by technology

[0005] ① The degree of classified collection of construction waste is not high, and most of them can only be collected in a mixed manner
[0006] ②The recycling rate of construction waste is low
[0007] ③ my country's construction waste treatment and resource utilization technology is backward, and urban construction waste is mostly treated by direct landfill, which not only occupies land but also pollutes the environment
[0008] ④ The investment in urban construction waste treatment is low, the policies, regulations and measures are not perfect, and the environmental protection awareness of construction workers is not strong

Embodiment Construction

[0025] Below by embodiment, technical process of the present invention is described in detail:

[0026] The utility model discloses a multi-functional and environment-friendly construction waste disposal process. The construction waste is firstly divided into concrete block waste and brick crumb waste.

[0027] The steps to deal with concrete waste are:

[0028] 1) Desilting: first remove 90% of the soil in the concrete waste through the desilting equipment;

[0029] 2) Coarse crushing: the concrete waste is crushed into aggregates with a particle size of 60-210mm by a jaw crusher;

[0030] 3) Magnetic separation: remove metal substances in aggregates;

[0031] 4) Fine crushing: the aggregate is crushed into waste concrete recycled aggregate with a particle size of 10-60mm by a hammer crusher;

[0032] Wherein, both the jaw crusher in step 2) and the hammer crusher in step 4) work with the cooperation of the dust collector.

[0033] The steps to deal with brick waste are: ...

Abstract

The invention provides a multifunctional environment-friendly construction waste disposal technology and relates to the field of construction waste disposal. Construction waste is divided into concrete block waste and brick dust block waste, then the concrete waste is sequentially subjected to silt removal, coarse breaking, magnetic separation and fine breaking to obtain waste concrete recycled aggregate, and the brick dust block waste is sequentially subjected to silt removal, coarse breaking, magnetic separation, secondary breaking, fine breaking, air classification and separation of light substances and screening to obtain waste brick recycled aggregate. The disposal technology is simple, cost is low, controllability is good, construction waste classified disposal is achieved, the technology is environmentally friendly and harmless, and occupational diseases caused by severe environments are avoided.

Description

technical field [0001] The invention relates to the field of construction waste disposal, in particular to a multifunctional environment-friendly construction waste disposal process. Background technique [0002] At present, the local government generally adopts the PPP model for the disposal of domestic construction waste, and seeks market capital to jointly implement the harmless, reduced, resource-based and industrialized disposal of construction waste by allocating land. [0003] The general disposal process is a simple production line, from crushing to screening to product production. Such a production line process cannot be classified for disposal and start-up operation at the same time, so that the high-strength concrete waste can be directly used for permeable bricks after crushing, which is not only a waste of resources, but also a waste of resources. It will also reduce economic benefits and delay the period of return on investment. For social capital and enterpri...
