Construction waste recycled aggregate treatment process and its device

Abstract

The invention provides a technology and a device for treating building garbage recycled aggregates. The technology is characterized by comprising the following steps: spraying water and precipitating dust; carrying out large-block crushing; loading into a bin; carrying out jaw crushing; conveying crushed aggregates; removing iron; carrying out hammer type crushing; and sieving. The device comprises a first iron remover and a second iron remover, and the structure and the connecting relationship of the first iron remover and the second iron remover are identical. The device comprises a permanent magnet, a first magnetic conductor and a second magnetic conductor are identical in structure and are both provided with arc-shaped grooves, the arc-shaped grooves of the two magnetic conductors are opposite, are simultaneously arranged on a support frame and are fixedly connected, arc-shaped magnetic conducting sheets are arranged in the arc-shaped grooves, a first non-magnetic-conducting body and a second non-magnetic-conducting body are identical in structure and are both provided with arc-shaped concave surfaces, the two non-magnetic-conducting bodies are arranged between the two magnetic conductors and are fixedly connected, the two arc-shaped magnetic conducting sheets and the two arc-shaped concave surfaces are alternately arranged along the periphery so as to form a cylindrical cavity, the permanent magnet is arranged in the cylindrical cavity and is connected in a sliding manner, and a rotary knob is arranged at the end part of the permanent magnet and is fixedly connected.

Description

technical field [0001] The invention relates to building materials, in particular to a production process for comprehensively utilizing construction waste to produce small-sized hollow blocks of light aggregate concrete, and is a construction waste recycled aggregate treatment process and a device thereof. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, a large amount of construction waste has been generated in the reconstruction of old cities and infrastructure construction, and most of the construction waste has been transported to the suburbs or villages for open-air stacking or landfill without any treatment. Construction waste Random stacking can easily cause safety hazards. It causes serious pollution to water resources and seriously affects air quality. It not only occupies a large amount of land and reduces soil quality, but also causes serious environmental pollution, directly endangering the lives...

Problems solved by technology

[0002] With the rapid development of my country's economy, the process of urbanization is accelerating, the reconstruction of old cities, infrastructure construction, etc. have produced a large amount of construction waste, and most of the construction waste is transported to the suburbs or villages for open-air stacking or landfill without any treatment. Random stacking can easily cause safety hazards, which cause serious pollution to water resources and seriously affect air quality. It not only takes up a lot of land and reduces soil quality, but also causes serious environmental pollution, directly endangering the lives of surrounding residents.
