Problems solved by technology

[0004] The above-mentioned "urban construction waste" treatment technical scheme is a centralized treatment method, so that effective resources cannot be effectively used according to its characteristics
To a certain extent, it has caused waste of resources and pollution of the environment.
For example: bricks and concrete are mixed together and processed together, and can only be used as roadbed and cushion, with limited economic benefits and low raw material utilization
And the sundries in the materials, such as wood blocks, plastics and other light substances will also be mixed in the finished materials in a large range, causing secondary pollution to the ground soil

Abstract

The invention relates to a construction waste treatment system. The construction waste treatment system comprises a feeder, a brick and concrete separator, a first jaw crusher, a first impact crusher, a second impact crusher, a first vibrating screen, a second vibrating screen and a light substance removing device, wherein the feeder, the brick and concrete separator, the first jaw crusher, the first impact crusher, the first vibrating screen and the light substance removing device are successively connected; the brick and concrete separator, the second impact crusher and the second vibrating screen are successively connected, and the second impact crusher is arranged below the brick and concrete separator. The construction waste treatment system provided by the invention can separate construction waste into bricks, concrete and other impurities, and through follow-up treatment, a brick material and a concrete material which are relatively high in purity can be obtained.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste treatment system. Background technique [0002] "Urban construction waste" is mainly composed of the following four components: 1. Brick and concrete mixture, 2. A large amount of muck, 3. A small amount of light impurities such as sawdust and clothing, 4. A small amount of sundries such as steel wrapped in concrete . [0003] The current "urban construction waste" treatment technology plan: mainly adopts centralized crushing and grading treatment methods, and performs overall treatment of bricks, concrete and light objects. All construction waste is mixed together and sent to the feed bin by a forklift. The material is fed smoothly and evenly through the "vibrating feeder" and directly sent to the "jaw crusher". The material crushed by the "jaw crusher" is transported to the "impact crusher" by the "belt conveyor", and iron removal is...
