Method for removing impurities from aggregate prepared from waste concrete

Abstract

The invention belongs to the field of construction waste utilization, and particularly relates to a method for removing impurities from an aggregate made of waste concrete, in particular to a device for removing the impurities from the recycled aggregate of waste concrete in the process of removing the impurities from the recycled aggregate of waste concrete. The device comprises a shell, a feeding port is arranged on the shell, and a second working space and a first working space with openings facing the feeding port side are formed in the shell; the first working space is closer to the feeding port than the second working space, a metal impurity treatment mechanism is arranged in the first working space, and a light impurity treatment mechanism is arranged in the second working space; the first transmission grooves are formed at the side, adjacent to a concrete hopper, in the shell, the first transmission grooves are closer to the feeding port, and the openings of the first transmission grooves face the feeding port side; the waste concrete is vibrated and dispersed on a vibrating plate, metal impurities in the waste concrete are adsorbed and removed through an electromagnet, and the adsorbed metal impurities are scraped into a metal collecting groove through the side wall of the metal collecting groove and through the rotation of the electromagnet, so that the iron and light impurities in the waste concrete can be effectively removed by machining the waste concrete through the technology and the device.

Description

Technical field [0001] The invention belongs to the field of construction waste, in particular, involving a method of abandoning concrete production of aggregate. Background technique [0002] With the development of China's urbanization process, construction waste emissions have grown year by year, and the proportion of renewable components is constantly improving most of the construction waste has not been treated. It is transported to the suburbs or around the surroundings, which is simple landfill or open-air, which is not only Wasing land and resources, also polluting the environment on the other hand, with the increasing population, the construction industry is growing, producing and utilizing construction waste recycled aggregates for saving resources, protecting the environment and implementation The sustainable development of the construction industry is of great significance, but in the abandoned concrete, it is low, and the broken light impurities is mixed in the concr...

AI Technical Summary

Problems solved by technology

[0002] With the development of my country's urbanization process, the discharge of construction waste is increasing year by year, and the proportion of renewable components is also increasing. Most of the construction waste is transported to the suburbs or around the city for simple landfill or open storage without any treatment. It wastes land and resources, and pollutes the environment. On the other hand, with the increasing population, the demand for sand and gravel aggregates in the construction industry continues to grow. The sustainable development of the construction industry is of great significance, but the efficiency of the waste concrete removal process is low, and the broken light impurities are mixed in the concrete, which is difficult to be found and removed, thus affecting the quality of the aggregate
