Embodiment 1

[0034] The processing method of the present invention is as follows, construction waste is transported in the factory by dump truck, is poured into the construction waste storage yard, and super-large block is broken with machinery, and is sterilized through medicine chlorine dioxide (also can select similar harmless disinfectant for use) Disinfectant) is loaded into the hopper with a loader after being sterilized, and sent to the sorting platform. Using manual or intelligent sorting machines, waste wood boards, cartons and waste paper, waste paint barrels and plastic sheets, waste gypsum boards and other substances are sorted out ( The sorted materials are regenerated separately), and the sorted construction waste is sent to the jaw crusher by the apron feeder for primary crushing and separation, and the primary crushed construction waste is separated by a magnetic separator to separate iron (sent to the ironworks in production), the construction waste fragments after magnetic...

Abstract

The present invention relates to a method for comprehensive treatment of building garbage. The method comprises: a, disinfecting building garbage to be treated with an agent; b, loading the building garbage obtained in the step a into a material hopper, transporting to a sorting platform, and sorting out debris; c, feeding the sorted building garbage into a jaw crusher through a plate type material feeder, and carrying out primary crushing; d, carrying out magnetic separation on the building garbage obtained in the step c with a magnetic separation machine, feeding into the material hopper ofan impact crusher, and carrying out final crushing with the impact crusher; and e, carrying out screening and peeling on the building garbage obtained in the step d by using a screening machine so asto obtain the sand and stone aggregate in concrete, feeding into a cleaning separation machine, carrying out cleaning separation, feeding into a coarse aggregate bin, and separating to obtain fine powder, wherein the fine aggregate separated by the cleaning separation is used as the raw material for dry powder mortar or pre-mixed mortar or concrete three-hole brick. According to the present invention, with the method, the building garbage resources can be subjected to comprehensive utilization, such that the building garbage can achieve ordered management, resource utilization and harmless treatment, and the purposes of land saving and secondary pollution reducing can be achieved.

Description

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. Background technique [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 of old...
