Construction waste regeneration treatment system and treatment method thereof

Abstract

The invention provides a construction waste regeneration treatment system and a treatment method thereof. The construction waste regeneration treatment system comprises a metal detection unit, a sorting unit, a crushing unit, a washing and filtering unit, a conveying unit and a precipitation unit. The construction waste regeneration treatment method comprises the following steps of metal detection, sorting, coarse crushing, water separation and filtering, precipitation and purification, conveying, fine crushing, and secondary water separation and filtering. According to the construction wasteregeneration treatment method, concrete is subjected to washing and filtering after coarse crushing and fine crushing, after concrete waste particles are put into water, loose parts and weathered parts in concrete waste are converted into smaller particles in water, then the concrete waste is filtered through a filter screen, infirm parts in the concrete waste can thus be effectively removed, andthe situation that the strength of the concrete waste serving as concrete aggregate is affected, and consequently the strength and the using safety of the concrete are affected is avoided.

Description

technical field [0001] The invention belongs to the technical field of construction waste treatment, and in particular relates to a construction waste regeneration treatment system and a treatment method thereof. Background technique [0002] Construction waste refers to the construction waste produced by man-made or natural reasons in the project, including waste residue, spoil, silt and waste materials, etc. If it is not processed and utilized in time, it will definitely bring adverse effects to society, the environment and resources , in which waste building concrete can produce coarse and fine aggregates, which can be used to produce concrete with corresponding strength grades. However, waste building concrete will be weathered to a certain extent during long-term use, resulting in a decrease in strength. If it is not removed, it will be Affect the quality and strength of recycled concrete. Therefore, the present invention proposes a construction waste regeneration treat...
