Example Embodiment

[0023] Implementation

[0024] In the following, the present invention will be further described in conjunction with specific embodiments. It should be understood that the following examples are only used to illustrate the present invention and not to limit the scope of the present invention.

[0025] The two-stage separation method for construction waste disposal of the present invention includes the following steps:

[0026] (1) Screening: Recycled materials are classified by a screening device to obtain coarse and fine aggregates. Recycled aggregates refer to construction waste after coarse and medium cracking.

[0027] In a preferred embodiment of the present invention, a drum-type cylindrical screen is used as the screening device, with 1 to 3 layers of screen cylinders, which are mainly used to separate and regenerate coarse and fine aggregates and separate some light combustibles into coarse aggregates. It is possible to separate light combustibles in the next step. Such as f...

Abstract

The invention discloses a two-stage separation method for disposing building garbage. Regenerated material obtained by carrying out coarse crushing and medium crushing on the building garbage is subjected to two-stage separation by virtue of a screening device and a winnowing device so as to obtain regenerated crude and fine aggregate and light combustible material. A drum cylinder screen is taken as the screening device, and a negative pressure winnowing device is adopted. The two-stage separation method for disposing the building garbage disclosed by the invention has high screening efficiency, a sieve is difficult to block up by wet material, moisture content of the material can be reduced, dust pollution is reduced, manual sorting is substituted, and mechanical separation is realized, thus the two-stage separation method for disposing the building garbage, disclosed by the invention, is applicable to popularization and application.

Description

technical field [0001] The invention relates to comprehensive utilization of construction waste resources, in particular to a two-stage separation method for construction waste disposal. Background technique [0002] Construction waste, especially demolished old construction waste, contains a small amount of light combustible materials such as wood, plastic, and fabric. In the process of harmless disposal of construction waste, light combustibles are not completely removed, and they are still mixed in recycled aggregates, which has different degrees of harm to the resource utilization of recycled aggregates, mainly reflected in the fact that the products made of recycled aggregates can be processed Poor performance, unstable quality, and poor durability. At present, most of the existing construction waste recycling enterprises at home and abroad, the method of removing light combustible materials such as wood blocks, plastics, fabrics, etc., is manual sorting, which is usua...
