Classified recycling treatment system and process for construction waste

Abstract

The invention discloses a construction waste classified recovery processing system and process in the technical field of construction waste classified recovery processing. The construction waste classified recovery processing system comprises a conveying mechanism and a magnetic separation mechanism, the magnetic separation mechanism is arranged on the outer side of the top of the conveying mechanism, and the conveying mechanism comprises four first rectangular supporting legs; conveying rollers are rotationally connected between the two first rectangular supporting legs on the same side, anda conveying belt is in transmission connection between the two conveying rollers. When the construction waste is continuously conveyed through the conveying belt, a scraping plate turns over the construction waste back and forth, magnetic materials adsorbed to the bottom of the strong magnet are cleaned in time while turning over is conducted, and therefore the efficiency and effect of separatingthe magnetic materials in the construction waste are improved, and the magnetic materials at the bottom of the strong magnet are cleaned in time; and the phenomenon of falling due to excessive adsorption is prevented.

Description

technical field [0001] The invention relates to the field of classification, recovery and treatment of construction waste, in particular to a system and process for the classification and recovery of construction waste. Background technique [0002] Construction waste refers to the general designation of muck, waste concrete, waste masonry and other waste generated in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries. Classified by source, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick fragments, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying con...

Problems solved by technology

[0006] The object of the present invention is to provide a sorting and recycling system and process for construction waste, so as to solve the problem that the non-magnetic waste is transported by the conveyor belt from the end of the conveyor belt when the magnetic material is separated and recovered by the garbage magnetic separation device proposed in the above-mentioned background technology. Dropping will wash down the magnetic material floating on the surface of the magnet, resulting in incomplete separation of the magnetic material, and when the garbage accumulates, the magnet cannot completely absorb the magnetic material, causing most of the magnetic material to fall with the garbage, and the separation effect is poor The problem
