Method for comprehensively treating construction waste

Abstract

The invention relates to a method for comprehensively treating construction waste, which comprises the following steps of: 1. disinfecting the construction waste to be treated by adopting a chlorine dioxide disinfectant; 2. loading the construction waste obtained from the step 1 to a hopper and conveying to a sorting platform to sort out impurities; 3. feeding the sorted construction waste to an edge-type crusher through a plate feeder to crush initially; 4. feeding the initially crushed construction waste to a hopper of an impact crusher after magnetic separation by a magnetic separator and crushing the construction waste finally by the impact crusher; 5. screening and peeling out sandstone materials from concrete and feeding the sandstone materials after being washed by a washer to a coarse aggregate bin, wherein the aggregate separated from the washed fine powder washed is used as raw materials of dry mortar or ready mixed mortar or three-hole brick of concrete. The invention ensures that the construction waste resources are utilized comprehensively, and the ordering management, the resource management and the harmless treatment of the construction waste are achieved, thereby achieving the purposes of saving land and reducing secondary pollution.

Description

1. Technical field [0001] The invention relates to a processing method for construction waste, in particular to a processing method for reusing construction waste after comprehensive processing. 2. Background technology [0002] With the rapid development of urban construction, the process of reconstruction and demolition brings a large amount of construction waste, which can be divided into: old building demolition waste, construction site waste, decoration waste and building material production waste. It is composed of slag, sand and gravel, waste mortar, concrete fragments, waste wood and waste decoration materials, etc. Some of the construction waste can be reused as renewable resources, such as: scrap metal can be reprocessed into steel products of various specifications, Waste wood can be used to make various man-made panels, etc., but there is currently no good way to utilize the waste materials such as broken bricks and concrete blocks brought about by the demolition...

AI Technical Summary

Problems solved by technology

[0004] Purpose of the invention: The present invention provides a method for comprehensive treatment of construction waste, the purpose of which is to solve the problem of poor treatment and recovery of construction waste such as muck, broken brick tiles, sand and stones, waste mortar, and concrete fragments. Utilization method, untreated construction waste is used as backfill, which causes increasingly serious pollution to the ecological environment, and also wastes a lot of non-renewable resources and other problems.
